Subject: [PATCH 002/435] feat: track and display honor/arena points from
 update fields

Add PLAYER_FIELD_HONOR_CURRENCY and PLAYER_FIELD_ARENA_CURRENCY to the
update field system for WotLK (indices 1422/1423) and TBC (1505/1506).
Parse values from both CREATE_OBJECT and VALUES update paths, and show
them in the character Stats tab under a PvP Currency section.

Subject: [PATCH 003/435] feat: implement equipment set save, update, and
 delete

Add saveEquipmentSet() and deleteEquipmentSet() methods that send
CMSG_EQUIPMENT_SET_SAVE and CMSG_DELETEEQUIPMENT_SET packets. The save
packet captures all 19 equipment slot GUIDs via packed GUID encoding.
The Outfits tab now always shows (not just when sets exist), with an
input field to create new sets and Update/Delete buttons per set.

Subject: [PATCH 004/435] fix: send CMSG_SET_WATCHED_FACTION when tracking a
 reputation

setWatchedFactionId() previously only stored the faction locally.
Now it also sends CMSG_SET_WATCHED_FACTION with the correct repListId
to the server, so the tracked faction persists across sessions.

Subject: [PATCH 005/435] fix: auto-acknowledge cinematic and movie triggers to
 prevent server hangs

Send CMSG_NEXT_CINEMATIC_CAMERA in response to SMSG_TRIGGER_CINEMATIC
and CMSG_COMPLETE_MOVIE in response to SMSG_TRIGGER_MOVIE. Some WotLK
servers block further packets or disconnect clients that don't respond
to these triggers, especially during the intro cinematic on first login.

Subject: [PATCH 006/435] fix: correct CMSG_EQUIPMENT_SET_USE packet format

The packet previously sent only a uint32 setId, which does not match
the WotLK protocol. AzerothCore/TrinityCore expect 19 iterations of
(PackedGuid itemGuid + uint8 srcBag + uint8 srcSlot). Now looks up the
equipment set's target item GUIDs and searches equipment, backpack, and
extra bags to provide correct source locations for each item.

 expansions

Classic and TBC lack equipment set opcodes, so sending save/use/delete
packets would transmit wire opcode 0xFFFF and potentially disconnect the
client. Now all three methods check wireOpcode != 0xFFFF before sending,
and the Outfits tab is only shown when the expansion supports equipment
sets (via supportsEquipmentSets() check).

Subject: [PATCH 008/435] fix: update local equipment set GUID on save
 confirmation and auto-request played time on login

SMSG_EQUIPMENT_SET_SAVED now updates the local set's GUID from the
server response, preventing duplicate set creation when clicking
"Update" on a newly-saved set. New sets are also added to the local
list immediately so the UI reflects them without a relog.

Additionally, CMSG_PLAYED_TIME is now auto-sent on initial world entry
(with sendToChat=false) so the character Stats tab shows total and
level time immediately without requiring /played.

Subject: [PATCH 009/435] feat: display detailed honor/arena/token costs for
 vendor items

Load ItemExtendedCost.dbc and show specific costs (e.g. "2000 Honor",
"200 Arena", "30x Badge of Justice") instead of generic "[Tokens]" for
vendor items with extended costs. Items with both gold and token costs
now show both. Token item names are resolved from item info cache.

Subject: [PATCH 010/435] feat: add "Usable" filter to auction house and query
 token item names

Add a "Usable" checkbox to the AH search UI that filters results to
items the player can actually equip/use (server-side filtering via the
usableOnly parameter in CMSG_AUCTION_LIST_ITEMS). Also ensure token
item names for extended costs are queried from the server via
ensureItemInfo() so they display properly instead of "Item#12345".

Subject: [PATCH 012/435] feat: use M2 animation duration for spell visual
 lifetime

Spell visual effects previously used a fixed 3.5s duration for all
effects, causing some to linger too long and overlap during combat.
Now queries the M2 model's default animation duration via the new
getInstanceAnimDuration() method and clamps it to 0.5-5s. Effects
without animations fall back to a 2s default. This makes spell impacts
feel more responsive and reduces visual clutter.

or GPU upload failure) were re-attempted on every subsequent spell cast,
causing repeated file I/O during combat. Now caches failed model IDs in
spellVisualFailedModels_ so they are skipped on subsequent attempts.

Subject: [PATCH 014/435] fix: increase compressed UPDATE_OBJECT decompressed
 size limit to 5MB

Capital cities and large raids can produce UPDATE_OBJECT packets that
decompress to more than 1MB. The real WoW client handles up to ~10MB.
Bump the limit from 1MB to 5MB to avoid silently dropping entity
updates in densely populated areas like Dalaran or 40-man raids.

The proficiency check added in the previous commit only applied to the

 mounted/swimming/flying/stealthed/channeling macro conditionals
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add commonly-used WoW macro conditionals that were missing:
- [mounted]/[nomounted] — checks isMounted() state
- [swimming]/[noswimming] — checks SWIMMING movement flag
- [flying]/[noflying] — checks CAN_FLY + FLYING movement flags
- [stealthed]/[nostealthed] — checks UNIT_FLAG_SNEAKING (0x02000000)
- [channeling]/[nochanneling] — checks if currently channeling a spell

These are essential for common macros like mount/dismount toggles,
rogue opener macros, and conditional cast sequences.

Subject: [PATCH 021/435] fix: implement [target=pet] and [@pet] macro target
 specifiers

The /macrohelp listed [target=pet] as supported but the conditional
evaluator didn't handle the "pet" specifier for target= or @ syntax.
Now resolves to the player's active pet GUID (or skips the alternative
if no pet is active). Essential for hunter/warlock macros like:
  /cast [target=pet] Mend Pet
  /cast [@pet,dead] Revive Pet

Subject: [PATCH 022/435] feat: add [raid], [noraid], and [spec:N] macro
 conditionals
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add commonly-used WoW macro conditionals:
- [raid]/[noraid] — checks if the player is in a raid group (groupType
  == 1) vs a regular party. Used for conditional healing/targeting in
  raid content.
- [spec:1]/[spec:2] — checks the active talent spec (1-based index).
  Used for dual-spec macros that swap gear sets or use different
  rotations per spec.

Updated /macrohelp to list the new conditionals.

Chat tabs with unread messages now pulse yellow to attract attention.
The existing unread count "(N)" suffix was text-only and easy to miss,
especially for whisper and guild tabs. The pulsing color clears when
the tab is clicked, matching standard WoW chat tab behavior.

Subject: [PATCH 024/435] fix: sync pending spell cooldowns to action bar after
 login

SMSG_SPELL_COOLDOWN arrives before SMSG_ACTION_BUTTONS during login,
so cooldown times were stored in spellCooldowns but never applied to
the newly populated action bar slots. Players would see all abilities
as ready immediately after login even if spells were on cooldown.
Now applies pending cooldowns from the spellCooldowns map to each
matching slot when the action bar is first populated.

SMSG_INITIAL_SPELLS cooldown entries have both cooldownMs (individual)
and categoryCooldownMs (shared, e.g. potions). The handler only checked
cooldownMs, so spells with category-only cooldowns (cooldownMs=0,

Subject: [PATCH 029/435] fix: raise initial spell count cap from 256 to 1024

WotLK characters with all ability ranks, mounts, companion pets,
professions, and racial skills can know 400-600 spells. The previous
256 cap truncated the spell list, causing missing spells in the
spellbook, broken /cast commands for truncated spells, and missing
cooldown tracking for spells beyond the cap.

Subject: [PATCH 030/435] fix: raise initial cooldown count cap from 256 to
 1024

Some server implementations include cooldown entries for all spells
(even with zero remaining time) to communicate category cooldown data.
The previous 256 cap could truncate these entries, causing missing
cooldown tracking for spells near the end of the list. Raised to match
the spell count cap for consistency.

Subject: [PATCH 031/435] fix: let FSR3 settings persist across restarts
 without env var

FSR2/FSR3 upscaling mode was forcibly reverted to FSR1 on every startup
unless the WOWEE_ALLOW_STARTUP_FSR2 environment variable was set. This
meant users had to re-select FSR 3.x and re-enable frame generation on
every launch. Removed the env var requirement since the deferred
activation (wait until IN_WORLD state) already provides sufficient
startup safety by preventing FSR init during login/character screens.

Subject: [PATCH 032/435] fix: sync item cooldowns to action bar slots on login

The cooldown sync after SMSG_ACTION_BUTTONS and SMSG_INITIAL_SPELLS
only handled SPELL-type action bar slots. ITEM-type slots (potions,
trinkets, engineering items) were skipped, so items on the action bar
showed no cooldown overlay after login even if their on-use spell was
on cooldown. Now looks up each item's on-use spell IDs from the item
info cache and syncs any matching spellCooldowns entries.

Subject: [PATCH 033/435] feat: show spell cooldown on macro action bar buttons
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Macro buttons on the action bar never showed cooldowns — a /cast
Fireball macro would display no cooldown sweep or timer even when
Fireball was on cooldown. Now resolves the macro's primary spell (from
the first /cast command, stripping conditionals and alternatives) and
checks its cooldown via spellCooldowns. The cooldown sweep overlay and
countdown text display using the resolved spell's remaining time.

Subject: [PATCH 034/435] refactor: cache macro primary spell ID to avoid
 per-frame name search

The macro cooldown display from the previous commit iterated all known
spells (400+) every frame for each macro on the action bar, doing
lowercase string comparisons. Moved the spell name resolution into a
cached lookup (macroPrimarySpellCache_) that only runs once per macro
and is invalidated when macro text is edited. The per-frame path now
just does a single hash map lookup + spellCooldowns check.

Subject: [PATCH 035/435] fix: key macro cooldown cache by macro ID instead of
 slot index

The macro primary spell cache was keyed by action bar slot index, so
switching characters or rearranging macros could return stale spell IDs
from the previous character's macro in that slot. Now keyed by macro ID,
which is stable per-macro regardless of which slot it occupies.

Subject: [PATCH 036/435] feat: show spell tooltip on macro action bar hover
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Hovering a macro button on the action bar previously showed "Macro #N"
with raw macro text. Now resolves the macro's primary spell via the
cached lookup and shows its full rich tooltip (name, school, cost, cast
time, range, description) — same as hovering a regular spell button.
Falls back to the raw text display if no primary spell is found.
Also shows the cooldown remaining in red when the spell is on cooldown.

Subject: [PATCH 037/435] feat: show out-of-range red tint on macro action bar

The out-of-range indicator (red tint) only applied to SPELL-type action
bar slots. Macro buttons like /cast Frostbolt never turned red even when
the target was out of range. Now resolves the macro's primary spell via
the cached lookup and checks its max range against the target distance,
giving the same visual feedback as regular spell buttons.

Subject: [PATCH 039/435] feat: show cast-failed red flash on macro action bar
 buttons

The error-flash overlay (red fade on spell cast failure) only applied to
SPELL-type slots. Macro buttons never flashed red when their primary
spell failed to cast. Now resolves the macro's primary spell and checks
the actionFlashEndTimes_ map for a matching flash, completing macro
action bar parity with spell buttons across all 6 visual indicators.

Subject: [PATCH 040/435] feat: support /castsequence macros for action bar
 icon and indicators

Macros with /castsequence were treated as having no primary spell, so
they showed no icon, cooldown, range, power, or tooltip on the action
bar. Now both resolveMacroPrimarySpellId() and the icon derivation
code recognize /castsequence commands, strip the reset= spec, and
use comma-separation to find the first spell in the sequence. This
gives /castsequence macros the same visual indicators as /cast macros.

Subject: [PATCH 041/435] fix: invalidate macro spell cache when spells are
 learned/removed

The macro primary spell cache stored 0 (no spell found) when a macro
referenced a spell the player hadn't learned yet. After learning the
spell from a trainer or leveling up, the cache was never refreshed,
so the macro button stayed broken. Now tracks the known spell count
and clears the cache when it changes, ensuring newly learned spells
are resolved on the next frame.

Macros with /use ItemName (e.g. /use Healthstone, /use Engineering
trinket) had no icon, cooldown, or tooltip on the action bar because
only /cast and /castsequence were recognized. Now the spell resolution
also handles /use by looking up the item name in the item info cache
and finding its on-use spell ID. Added getItemInfoCache() accessor.

Subject: [PATCH 043/435] fix: clear spell visual negative cache on world entry

The spell visual failed-model cache was never cleared across world
changes, so models that failed to load during initial asset loading
(before MPQ/CASC data was fully indexed) would never retry. Now clears
spellVisualFailedModels_ in resetCombatVisualState() alongside the
active spell visual cleanup, giving failed models a fresh attempt on
each world entry.

The /help text was missing several commonly-used commands: /castsequence,
/use, /threat, /combatlog, /mark, /raidinfo, /assist, /inspect,
/chathelp. Reorganized categories for clarity and added all missing
entries to match the expanded auto-complete list.

Add [target=mouseover] and the @ shorthand syntax (@focus, @pet,

commonly used for mouseover healing macros and were already supported
but not documented in the in-game help.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Quest tracking choices (right-click → Track on the quest objective
tracker) were lost on logout because trackedQuestIds_ was not saved
in the character config. Now saves tracked quest IDs as a comma-
separated list and restores them on login, so the quest tracker
shows the same quests the player chose to track in their previous
session.

Subject: [PATCH 048/435] fix: save character config when quest tracking
 changes

setQuestTracked() modified trackedQuestIds_ but didn't call
saveCharacterConfig(), so tracked quests were only persisted if
another action (like editing a macro or rearranging the action bar)
happened to trigger a save before logout. Now saves immediately
when quests are tracked or untracked.

Macros with /use ItemName tried to find the item as a spell name for
icon resolution, which fails for items without a matching spell (e.g.
engineering trinkets, quest items). Now falls back to searching the
item info cache by name and showing the item's display icon when no
spell name matches.

Subject: [PATCH 050/435] feat: show item tooltip for /use macros when spell
 tooltip unavailable

When hovering a /use macro whose item's on-use spell isn't in the DBC
(no rich spell tooltip available), the tooltip fell back to showing raw
macro text. Now searches the item info cache and shows the full item
tooltip (stats, quality, binding, description) as a more useful
fallback for /use macros.

Subject: [PATCH 051/435] feat: add Lua 5.1 addon system with .toc loader and
 /run command

Foundation for WoW-compatible addon support:

- Vendor Lua 5.1.5 source as a static library (extern/lua-5.1.5)
- TocParser: parses .toc files (## directives + file lists)
- LuaEngine: Lua 5.1 VM with sandboxed stdlib (no io/os/debug),
  WoW-compatible print() that outputs to chat, GetTime() stub
- AddonManager: scans Data/interface/AddOns/ for .toc files,
  loads .lua files on world entry, skips LoadOnDemand addons
- /run <code> slash command for inline Lua execution
- HelloWorld test addon that prints to chat on load

Integration: AddonManager initialized after asset manager, addons
loaded once on first world entry, reset on logout. XML frame
parsing is deferred to a future step.

+HISTORY for Lua 5.1
+
+* Changes from version 5.0 to 5.1
+  -------------------------------
+  Language:
+  + new module system.
+  + new semantics for control variables of fors.
+  + new semantics for setn/getn.
+  + new syntax/semantics for varargs.
+  + new long strings and comments.
+  + new `mod' operator (`%')
+  + new length operator #t
+  + metatables for all types
+  API:
+  + new functions: lua_createtable, lua_get(set)field, lua_push(to)integer.
+  + user supplies memory allocator (lua_open becomes lua_newstate).
+  + luaopen_* functions must be called through Lua.
+  Implementation:
+  + new configuration scheme via luaconf.h.
+  + incremental garbage collection.
+  + better handling of end-of-line in the lexer.
+  + fully reentrant parser (new Lua function `load')
+  + better support for 64-bit machines.
+  + native loadlib support for Mac OS X.
+  + standard distribution in only one library (lualib.a merged into lua.a)
+
+* Changes from version 4.0 to 5.0
+  -------------------------------
+  Language:
+  + lexical scoping.
+  + Lua coroutines.
+  + standard libraries now packaged in tables.
+  + tags replaced by metatables and tag methods replaced by metamethods,
+    stored in metatables.
+  + proper tail calls.
+  + each function can have its own global table, which can be shared.
+  + new __newindex metamethod, called when we insert a new key into a table.
+  + new block comments: --[[ ... ]].
+  + new generic for.
+  + new weak tables.
+  + new boolean type.
+  + new syntax "local function".
+  + (f()) returns the first value returned by f.
+  + {f()} fills a table with all values returned by f.
+  + \n ignored in [[\n .
+  + fixed and-or priorities.
+  + more general syntax for function definition (e.g. function a.x.y:f()...end).
+  + more general syntax for function calls (e.g. (print or write)(9)).
+  + new functions (time/date, tmpfile, unpack, require, load*, etc.).
+  API:
+  + chunks are loaded by using lua_load; new luaL_loadfile and luaL_loadbuffer.
+  + introduced lightweight userdata, a simple "void*" without a metatable.
+  + new error handling protocol: the core no longer prints error messages;
+    all errors are reported to the caller on the stack.
+  + new lua_atpanic for host cleanup.
+  + new, signal-safe, hook scheme.
+  Implementation:
+  + new license: MIT.
+  + new, faster, register-based virtual machine.
+  + support for external multithreading and coroutines.
+  + new and consistent error message format.
+  + the core no longer needs "stdio.h" for anything (except for a single
+    use of sprintf to convert numbers to strings).
+  + lua.c now runs the environment variable LUA_INIT, if present. It can
+    be "@filename", to run a file, or the chunk itself.
+  + support for user extensions in lua.c.
+    sample implementation given for command line editing.
+  + new dynamic loading library, active by default on several platforms.
+  + safe garbage-collector metamethods.
+  + precompiled bytecodes checked for integrity (secure binary dostring).
+  + strings are fully aligned.
+  + position capture in string.find.
+  + read('*l') can read lines with embedded zeros.
+
+* Changes from version 3.2 to 4.0
+  -------------------------------
+  Language:
+  + new "break" and "for" statements (both numerical and for tables).
+  + uniform treatment of globals: globals are now stored in a Lua table.
+  + improved error messages.
+  + no more '$debug': full speed *and* full debug information.
+  + new read form: read(N) for next N bytes.
+  + general read patterns now deprecated.
+    (still available with -DCOMPAT_READPATTERNS.)
+  + all return values are passed as arguments for the last function
+    (old semantics still available with -DLUA_COMPAT_ARGRET)
+  + garbage collection tag methods for tables now deprecated.
+  + there is now only one tag method for order.
+  API:
+  + New API: fully re-entrant, simpler, and more efficient.
+  + New debug API.
+  Implementation:
+  + faster than ever: cleaner virtual machine and new hashing algorithm.
+  + non-recursive garbage-collector algorithm.
+  + reduced memory usage for programs with many strings.
+  + improved treatment for memory allocation errors.
+  + improved support for 16-bit machines (we hope).
+  + code now compiles unmodified as both ANSI C and C++.
+  + numbers in bases other than 10 are converted using strtoul.
+  + new -f option in Lua to support #! scripts.
+  + luac can now combine text and binaries.
+
+* Changes from version 3.1 to 3.2
+  -------------------------------
+  + redirected all output in Lua's core to _ERRORMESSAGE and _ALERT.
+  + increased limit on the number of constants and globals per function
+    (from 2^16 to 2^24).
+  + debugging info (lua_debug and hooks) moved into lua_state and new API
+    functions provided to get and set this info.
+  + new debug lib gives full debugging access within Lua.
+  + new table functions "foreachi", "sort", "tinsert", "tremove", "getn".
+  + new io functions "flush", "seek".
+
+* Changes from version 3.0 to 3.1
+  -------------------------------
+  + NEW FEATURE: anonymous functions with closures (via "upvalues").
+  + new syntax:
+    - local variables in chunks.
+    - better scope control with DO block END.
+    - constructors can now be also written: { record-part; list-part }.
+    - more general syntax for function calls and lvalues, e.g.:
+      f(x).y=1
+      o:f(x,y):g(z)
+      f"string" is sugar for f("string")
+  + strings may now contain arbitrary binary data (e.g., embedded zeros).
+  + major code re-organization and clean-up; reduced module interdependecies.
+  + no arbitrary limits on the total number of constants and globals.
+  + support for multiple global contexts.
+  + better syntax error messages.
+  + new traversal functions "foreach" and "foreachvar".
+  + the default for numbers is now double.
+    changing it to use floats or longs is easy.
+  + complete debug information stored in pre-compiled chunks.
+  + sample interpreter now prompts user when run interactively, and also
+    handles control-C interruptions gracefully.
+
+* Changes from version 2.5 to 3.0
+  -------------------------------
+  + NEW CONCEPT: "tag methods".
+    Tag methods replace fallbacks as the meta-mechanism for extending the
+    semantics of Lua. Whereas fallbacks had a global nature, tag methods
+    work on objects having the same tag (e.g., groups of tables).
+    Existing code that uses fallbacks should work without change.
+  + new, general syntax for constructors {[exp] = exp, ... }.
+  + support for handling variable number of arguments in functions (varargs).
+  + support for conditional compilation ($if ... $else ... $end).
+  + cleaner semantics in API simplifies host code.
+  + better support for writing libraries (auxlib.h).
+  + better type checking and error messages in the standard library.
+  + luac can now also undump.
+
+* Changes from version 2.4 to 2.5
+  -------------------------------
+  + io and string libraries are now based on pattern matching;
+    the old libraries are still available for compatibility
+  + dofile and dostring can now return values (via return statement)
+  + better support for 16- and 64-bit machines
+  + expanded documentation, with more examples
+
+* Changes from version 2.2 to 2.4
+  -------------------------------
+  + external compiler creates portable binary files that can be loaded faster
+  + interface for debugging and profiling
+  + new "getglobal" fallback
+  + new functions for handling references to Lua objects
+  + new functions in standard lib
+  + only one copy of each string is stored
+  + expanded documentation, with more examples
+
+* Changes from version 2.1 to 2.2
+  -------------------------------
+  + functions now may be declared with any "lvalue" as a name
+  + garbage collection of functions
+  + support for pipes
+
+* Changes from version 1.1 to 2.1
+  -------------------------------
+  + object-oriented support
+  + fallbacks
+  + simplified syntax for tables
+  + many internal improvements

+INSTALL for Lua 5.1
+
+* Building Lua
+  ------------
+  Lua is built in the src directory, but the build process can be
+  controlled from the top-level Makefile.
+
+  Building Lua on Unix systems should be very easy. First do "make" and
+  see if your platform is listed. If so, just do "make xxx", where xxx
+  is your platform name. The platforms currently supported are:
+    aix ansi bsd freebsd generic linux macosx mingw posix solaris
+
+  If your platform is not listed, try the closest one or posix, generic,
+  ansi, in this order.
+
+  See below for customization instructions and for instructions on how
+  to build with other Windows compilers.
+
+  If you want to check that Lua has been built correctly, do "make test"
+  after building Lua. Also, have a look at the example programs in test.
+
+* Installing Lua
+  --------------
+  Once you have built Lua, you may want to install it in an official
+  place in your system. In this case, do "make install". The official
+  place and the way to install files are defined in Makefile. You must
+  have the right permissions to install files.
+
+  If you want to build and install Lua in one step, do "make xxx install",
+  where xxx is your platform name.
+
+  If you want to install Lua locally, then do "make local". This will
+  create directories bin, include, lib, man, and install Lua there as
+  follows:
+
+    bin:	lua luac
+    include:	lua.h luaconf.h lualib.h lauxlib.h lua.hpp
+    lib:	liblua.a
+    man/man1:	lua.1 luac.1
+
+  These are the only directories you need for development.
+
+  There are man pages for lua and luac, in both nroff and html, and a
+  reference manual in html in doc, some sample code in test, and some
+  useful stuff in etc. You don't need these directories for development.
+
+  If you want to install Lua locally, but in some other directory, do
+  "make install INSTALL_TOP=xxx", where xxx is your chosen directory.
+
+  See below for instructions for Windows and other systems.
+
+* Customization
+  -------------
+  Three things can be customized by editing a file:
+    - Where and how to install Lua -- edit Makefile.
+    - How to build Lua -- edit src/Makefile.
+    - Lua features -- edit src/luaconf.h.
+
+  You don't actually need to edit the Makefiles because you may set the
+  relevant variables when invoking make.
+
+  On the other hand, if you need to select some Lua features, you'll need
+  to edit src/luaconf.h. The edited file will be the one installed, and
+  it will be used by any Lua clients that you build, to ensure consistency.
+
+  We strongly recommend that you enable dynamic loading. This is done
+  automatically for all platforms listed above that have this feature
+  (and also Windows). See src/luaconf.h and also src/Makefile.
+
+* Building Lua on Windows and other systems
+  -----------------------------------------
+  If you're not using the usual Unix tools, then the instructions for
+  building Lua depend on the compiler you use. You'll need to create
+  projects (or whatever your compiler uses) for building the library,
+  the interpreter, and the compiler, as follows:
+
+  library:	lapi.c lcode.c ldebug.c ldo.c ldump.c lfunc.c lgc.c llex.c
+		lmem.c lobject.c lopcodes.c lparser.c lstate.c lstring.c
+		ltable.c ltm.c lundump.c lvm.c lzio.c
+		lauxlib.c lbaselib.c ldblib.c liolib.c lmathlib.c loslib.c
+		ltablib.c lstrlib.c loadlib.c linit.c
+
+  interpreter:	library, lua.c
+
+  compiler:	library, luac.c print.c
+
+  If you use Visual Studio .NET, you can use etc/luavs.bat in its
+  "Command Prompt".
+
+  If all you want is to build the Lua interpreter, you may put all .c files
+  in a single project, except for luac.c and print.c. Or just use etc/all.c.
+
+  To use Lua as a library in your own programs, you'll need to know how to
+  create and use libraries with your compiler.
+
+  As mentioned above, you may edit luaconf.h to select some features before
+  building Lua.
+

+
+* What is Lua?
+  ------------
+  Lua is a powerful, light-weight programming language designed for extending
+  applications. Lua is also frequently used as a general-purpose, stand-alone
+  language. Lua is free software.
+
+  For complete information, visit Lua's web site at http://www.lua.org/ .
+  For an executive summary, see http://www.lua.org/about.html .
+
+  Lua has been used in many different projects around the world.
+  For a short list, see http://www.lua.org/uses.html .
+
+* Availability
+  ------------
+  Lua is freely available for both academic and commercial purposes.
+  See COPYRIGHT and http://www.lua.org/license.html for details.
+  Lua can be downloaded at http://www.lua.org/download.html .
+
+* Installation
+  ------------
+  Lua is implemented in pure ANSI C, and compiles unmodified in all known
+  platforms that have an ANSI C compiler. In most Unix-like platforms, simply
+  do "make" with a suitable target. See INSTALL for detailed instructions.
+
+* Origin
+  ------
+  Lua is developed at Lua.org, a laboratory of the Department of Computer
+  Science of PUC-Rio (the Pontifical Catholic University of Rio de Janeiro
+  in Brazil).
+  For more information about the authors, see http://www.lua.org/authors.html .

+.SH NAME
+lua \- Lua interpreter
+.SH SYNOPSIS
+.B lua
+[
+.I options
+]
+[
+.I script
+[
+.I args
+]
+]
+.SH DESCRIPTION
+.B lua
+is the stand-alone Lua interpreter.
+It loads and executes Lua programs,
+either in textual source form or
+in precompiled binary form.
+(Precompiled binaries are output by
+.BR luac ,
+the Lua compiler.)
+.B lua
+can be used as a batch interpreter and also interactively.
+.LP
+The given
+.I options
+(see below)
+are executed and then
+the Lua program in file
+.I script
+is loaded and executed.
+The given
+.I args
+are available to
+.I script
+as strings in a global table named
+.BR arg .
+If these arguments contain spaces or other characters special to the shell,
+then they should be quoted
+(but note that the quotes will be removed by the shell).
+The arguments in
+.B arg
+start at 0,
+which contains the string
+.RI ' script '.
+The index of the last argument is stored in
+.BR arg.n .
+The arguments given in the command line before
+.IR script ,
+including the name of the interpreter,
+are available in negative indices in
+.BR arg .
+.LP
+At the very start,
+before even handling the command line,
+.B lua
+executes the contents of the environment variable
+.BR LUA_INIT ,
+if it is defined.
+If the value of
+.B LUA_INIT
+is of the form
+.RI '@ filename ',
+then
+.I filename
+is executed.
+Otherwise, the string is assumed to be a Lua statement and is executed.
+.LP
+Options start with
+.B '\-'
+and are described below.
+You can use
+.B "'\--'"
+to signal the end of options.
+.LP
+If no arguments are given,
+then
+.B "\-v \-i"
+is assumed when the standard input is a terminal;
+otherwise,
+.B "\-"
+is assumed.
+.LP
+In interactive mode,
+.B lua
+prompts the user,
+reads lines from the standard input,
+and executes them as they are read.
+If a line does not contain a complete statement,
+then a secondary prompt is displayed and
+lines are read until a complete statement is formed or
+a syntax error is found.
+So, one way to interrupt the reading of an incomplete statement is
+to force a syntax error:
+adding a
+.B ';' 
+in the middle of a statement is a sure way of forcing a syntax error
+(except inside multiline strings and comments; these must be closed explicitly).
+If a line starts with
+.BR '=' ,
+then
+.B lua
+displays the values of all the expressions in the remainder of the
+line. The expressions must be separated by commas.
+The primary prompt is the value of the global variable
+.BR _PROMPT ,
+if this value is a string;
+otherwise, the default prompt is used.
+Similarly, the secondary prompt is the value of the global variable
+.BR _PROMPT2 .
+So,
+to change the prompts,
+set the corresponding variable to a string of your choice.
+You can do that after calling the interpreter
+or on the command line
+(but in this case you have to be careful with quotes
+if the prompt string contains a space; otherwise you may confuse the shell.)
+The default prompts are "> " and ">> ".
+.SH OPTIONS
+.TP
+.B \-
+load and execute the standard input as a file,
+that is,
+not interactively,
+even when the standard input is a terminal.
+.TP
+.BI \-e " stat"

+You need to quote
+.I stat 
+if it contains spaces, quotes,
+or other characters special to the shell.

+.I script
+is executed.
+.TP
+.BI \-l " name"

+.SH NAME
+luac \- Lua compiler
+.SH SYNOPSIS
+.B luac
+[
+.I options
+] [
+.I filenames
+]
+.SH DESCRIPTION
+.B luac
+is the Lua compiler.
+It translates programs written in the Lua programming language
+into binary files that can be later loaded and executed.
+.LP
+The main advantages of precompiling chunks are:
+faster loading,
+protecting source code from accidental user changes,
+and
+off-line syntax checking.
+.LP
+Pre-compiling does not imply faster execution
+because in Lua chunks are always compiled into bytecodes before being executed.
+.B luac
+simply allows those bytecodes to be saved in a file for later execution.
+.LP
+Pre-compiled chunks are not necessarily smaller than the corresponding source.
+The main goal in pre-compiling is faster loading.
+.LP
+The binary files created by
+.B luac
+are portable only among architectures with the same word size and byte order.
+.LP
+.B luac
+produces a single output file containing the bytecodes
+for all source files given.
+By default,
+the output file is named
+.BR luac.out ,
+but you can change this with the
+.B \-o
+option.
+.LP
+In the command line,
+you can mix
+text files containing Lua source and
+binary files containing precompiled chunks.
+This is useful to combine several precompiled chunks,
+even from different (but compatible) platforms,
+into a single precompiled chunk.
+.LP
+You can use
+.B "'\-'"
+to indicate the standard input as a source file
+and
+.B "'\--'"
+to signal the end of options
+(that is,
+all remaining arguments will be treated as files even if they start with
+.BR "'\-'" ).
+.LP
+The internal format of the binary files produced by

+]
+<H2>DESCRIPTION</H2>
+<B>luac</B>
+is the Lua compiler.
+It translates programs written in the Lua programming language
+into binary files that can be later loaded and executed.
+<P>
+The main advantages of precompiling chunks are:
+faster loading,
+protecting source code from accidental user changes,
+and
+off-line syntax checking.
+<P>
+Precompiling does not imply faster execution
+because in Lua chunks are always compiled into bytecodes before being executed.
+<B>luac</B>
+simply allows those bytecodes to be saved in a file for later execution.
+<P>
+Precompiled chunks are not necessarily smaller than the corresponding source.
+The main goal in precompiling is faster loading.
+<P>
+The binary files created by
+<B>luac</B>
+are portable only among architectures with the same word size and byte order.
+<P>
+<B>luac</B>
+produces a single output file containing the bytecodes
+for all source files given.
+By default,
+the output file is named
+<B>luac.out</B>,
+but you can change this with the
+<B>-o</B>
+option.
+<P>
+In the command line,
+you can mix
+text files containing Lua source and
+binary files containing precompiled chunks.
+This is useful because several precompiled chunks,
+even from different (but compatible) platforms,
+can be combined into a single precompiled chunk.
+<P>
+You can use
+<B>'-'</B>
+to indicate the standard input as a source file
+and
+<B>'--'</B>
+to signal the end of options
+(that is,
+all remaining arguments will be treated as files even if they start with
+<B>'-'</B>).
+<P>
+The internal format of the binary files produced by
+<B>luac</B>
+is likely to change when a new version of Lua is released.
+So,
+save the source files of all Lua programs that you precompile.

+<h1>1 - <a name="1">Introduction</a></h1>
+
+<p>
+Lua is an extension programming language designed to support
+general procedural programming with data description
+facilities.
+It also offers good support for object-oriented programming,
+functional programming, and data-driven programming.
+Lua is intended to be used as a powerful, light-weight
+scripting language for any program that needs one.
+Lua is implemented as a library, written in <em>clean</em> C
+(that is, in the common subset of ANSI&nbsp;C and C++).
+
+
+<p>
+Being an extension language, Lua has no notion of a "main" program:
+it only works <em>embedded</em> in a host client,
+called the <em>embedding program</em> or simply the <em>host</em>.
+This host program can invoke functions to execute a piece of Lua code,
+can write and read Lua variables,
+and can register C&nbsp;functions to be called by Lua code.
+Through the use of C&nbsp;functions, Lua can be augmented to cope with
+a wide range of different domains,
+thus creating customized programming languages sharing a syntactical framework.
+The Lua distribution includes a sample host program called <code>lua</code>,
+which uses the Lua library to offer a complete, stand-alone Lua interpreter.
+
+
+<p>
+Lua is free software,
+and is provided as usual with no guarantees,
+as stated in its license.
+The implementation described in this manual is available
+at Lua's official web site, <code>www.lua.org</code>.
+
+
+<p>
+Like any other reference manual,
+this document is dry in places.
+For a discussion of the decisions behind the design of Lua,
+see the technical papers available at Lua's web site.
+For a detailed introduction to programming in Lua,
+see Roberto's book, <em>Programming in Lua (Second Edition)</em>.
+
+
+
+<h1>2 - <a name="2">The Language</a></h1>
+
+<p>
+This section describes the lexis, the syntax, and the semantics of Lua.
+In other words,
+this section describes
+which tokens are valid,
+how they can be combined,
+and what their combinations mean.
+
+
+<p>
+The language constructs will be explained using the usual extended BNF notation,
+in which
+{<em>a</em>}&nbsp;means&nbsp;0 or more <em>a</em>'s, and
+[<em>a</em>]&nbsp;means an optional <em>a</em>.
+Non-terminals are shown like non-terminal,
+keywords are shown like <b>kword</b>,
+and other terminal symbols are shown like `<b>=</b>&acute;.
+The complete syntax of Lua can be found in <a href="#8">&sect;8</a>
+at the end of this manual.
+
+
+
+<h2>2.1 - <a name="2.1">Lexical Conventions</a></h2>
+
+<p>
+<em>Names</em>
+(also called <em>identifiers</em>)
+in Lua can be any string of letters,
+digits, and underscores,
+not beginning with a digit.
+This coincides with the definition of names in most languages.
+(The definition of letter depends on the current locale:
+any character considered alphabetic by the current locale
+can be used in an identifier.)
+Identifiers are used to name variables and table fields.
+
+
+<p>
+The following <em>keywords</em> are reserved
+and cannot be used as names:
+
+
+<pre>
+     and       break     do        else      elseif
+     end       false     for       function  if
+     in        local     nil       not       or
+     repeat    return    then      true      until     while
+</pre>
+
+<p>
+Lua is a case-sensitive language:
+<code>and</code> is a reserved word, but <code>And</code> and <code>AND</code>
+are two different, valid names.
+As a convention, names starting with an underscore followed by
+uppercase letters (such as <a href="#pdf-_VERSION"><code>_VERSION</code></a>)
+are reserved for internal global variables used by Lua.
+
+
+<p>
+The following strings denote other tokens:
+
+<pre>
+     +     -     *     /     %     ^     #
+     ==    ~=    &lt;=    &gt;=    &lt;     &gt;     =
+     (     )     {     }     [     ]
+     ;     :     ,     .     ..    ...
+</pre>
+
+<p>
+<em>Literal strings</em>
+can be delimited by matching single or double quotes,
+and can contain the following C-like escape sequences:
+'<code>\a</code>' (bell),
+'<code>\b</code>' (backspace),
+'<code>\f</code>' (form feed),
+'<code>\n</code>' (newline),
+'<code>\r</code>' (carriage return),
+'<code>\t</code>' (horizontal tab),
+'<code>\v</code>' (vertical tab),
+'<code>\\</code>' (backslash),
+'<code>\"</code>' (quotation mark [double quote]),
+and '<code>\'</code>' (apostrophe [single quote]).
+Moreover, a backslash followed by a real newline
+results in a newline in the string.
+A character in a string can also be specified by its numerical value
+using the escape sequence <code>\<em>ddd</em></code>,
+where <em>ddd</em> is a sequence of up to three decimal digits.
+(Note that if a numerical escape is to be followed by a digit,
+it must be expressed using exactly three digits.)
+Strings in Lua can contain any 8-bit value, including embedded zeros,
+which can be specified as '<code>\0</code>'.
+
+
+<p>
+Literal strings can also be defined using a long format
+enclosed by <em>long brackets</em>.
+We define an <em>opening long bracket of level <em>n</em></em> as an opening
+square bracket followed by <em>n</em> equal signs followed by another
+opening square bracket.
+So, an opening long bracket of level&nbsp;0 is written as <code>[[</code>,
+an opening long bracket of level&nbsp;1 is written as <code>[=[</code>,
+and so on.
+A <em>closing long bracket</em> is defined similarly;
+for instance, a closing long bracket of level&nbsp;4 is written as <code>]====]</code>.
+A long string starts with an opening long bracket of any level and
+ends at the first closing long bracket of the same level.
+Literals in this bracketed form can run for several lines,
+do not interpret any escape sequences,
+and ignore long brackets of any other level.
+They can contain anything except a closing bracket of the proper level.
+
+
+<p>
+For convenience,
+when the opening long bracket is immediately followed by a newline,
+the newline is not included in the string.
+As an example, in a system using ASCII
+(in which '<code>a</code>' is coded as&nbsp;97,
+newline is coded as&nbsp;10, and '<code>1</code>' is coded as&nbsp;49),
+the five literal strings below denote the same string:
+
+<pre>
+     a = 'alo\n123"'
+     a = "alo\n123\""
+     a = '\97lo\10\04923"'
+     a = [[alo
+     123"]]
+     a = [==[
+     alo
+     123"]==]
+</pre>
+
+<p>
+A <em>numerical constant</em> can be written with an optional decimal part
+and an optional decimal exponent.
+Lua also accepts integer hexadecimal constants,
+by prefixing them with <code>0x</code>.
+Examples of valid numerical constants are
+
+<pre>
+     3   3.0   3.1416   314.16e-2   0.31416E1   0xff   0x56
+</pre>
+
+<p>
+A <em>comment</em> starts with a double hyphen (<code>--</code>)
+anywhere outside a string.
+If the text immediately after <code>--</code> is not an opening long bracket,
+the comment is a <em>short comment</em>,
+which runs until the end of the line.
+Otherwise, it is a <em>long comment</em>,
+which runs until the corresponding closing long bracket.
+Long comments are frequently used to disable code temporarily.
+
+
+
+
+
+<h2>2.2 - <a name="2.2">Values and Types</a></h2>
+
+<p>
+Lua is a <em>dynamically typed language</em>.
+This means that
+variables do not have types; only values do.
+There are no type definitions in the language.
+All values carry their own type.
+
+
+<p>
+All values in Lua are <em>first-class values</em>.
+This means that all values can be stored in variables,
+passed as arguments to other functions, and returned as results.
+
+
+<p>
+There are eight basic types in Lua:
+<em>nil</em>, <em>boolean</em>, <em>number</em>,
+<em>string</em>, <em>function</em>, <em>userdata</em>,
+<em>thread</em>, and <em>table</em>.
+<em>Nil</em> is the type of the value <b>nil</b>,
+whose main property is to be different from any other value;
+it usually represents the absence of a useful value.
+<em>Boolean</em> is the type of the values <b>false</b> and <b>true</b>.
+Both <b>nil</b> and <b>false</b> make a condition false;
+any other value makes it true.
+<em>Number</em> represents real (double-precision floating-point) numbers.
+(It is easy to build Lua interpreters that use other
+internal representations for numbers,
+such as single-precision float or long integers;
+see file <code>luaconf.h</code>.)
+<em>String</em> represents arrays of characters.
+
+Lua is 8-bit clean:
+strings can contain any 8-bit character,
+including embedded zeros ('<code>\0</code>') (see <a href="#2.1">&sect;2.1</a>).
+
+
+<p>
+Lua can call (and manipulate) functions written in Lua and
+functions written in C
+(see <a href="#2.5.8">&sect;2.5.8</a>).
+
+
+<p>
+The type <em>userdata</em> is provided to allow arbitrary C&nbsp;data to
+be stored in Lua variables.
+This type corresponds to a block of raw memory
+and has no pre-defined operations in Lua,
+except assignment and identity test.
+However, by using <em>metatables</em>,
+the programmer can define operations for userdata values
+(see <a href="#2.8">&sect;2.8</a>).
+Userdata values cannot be created or modified in Lua,
+only through the C&nbsp;API.
+This guarantees the integrity of data owned by the host program.
+
+
+<p>
+The type <em>thread</em> represents independent threads of execution
+and it is used to implement coroutines (see <a href="#2.11">&sect;2.11</a>).
+Do not confuse Lua threads with operating-system threads.
+Lua supports coroutines on all systems,
+even those that do not support threads.
+
+
+<p>
+The type <em>table</em> implements associative arrays,
+that is, arrays that can be indexed not only with numbers,
+but with any value (except <b>nil</b>).
+Tables can be <em>heterogeneous</em>;
+that is, they can contain values of all types (except <b>nil</b>).
+Tables are the sole data structuring mechanism in Lua;
+they can be used to represent ordinary arrays,
+symbol tables, sets, records, graphs, trees, etc.
+To represent records, Lua uses the field name as an index.
+The language supports this representation by
+providing <code>a.name</code> as syntactic sugar for <code>a["name"]</code>.
+There are several convenient ways to create tables in Lua
+(see <a href="#2.5.7">&sect;2.5.7</a>).
+
+
+<p>
+Like indices,
+the value of a table field can be of any type (except <b>nil</b>).
+In particular,
+because functions are first-class values,
+table fields can contain functions.
+Thus tables can also carry <em>methods</em> (see <a href="#2.5.9">&sect;2.5.9</a>).
+
+
+<p>
+Tables, functions, threads, and (full) userdata values are <em>objects</em>:
+variables do not actually <em>contain</em> these values,
+only <em>references</em> to them.
+Assignment, parameter passing, and function returns
+always manipulate references to such values;
+these operations do not imply any kind of copy.
+
+
+<p>
+The library function <a href="#pdf-type"><code>type</code></a> returns a string describing the type
+of a given value.
+
+
+
+<h3>2.2.1 - <a name="2.2.1">Coercion</a></h3>
+
+<p>
+Lua provides automatic conversion between
+string and number values at run time.
+Any arithmetic operation applied to a string tries to convert
+this string to a number, following the usual conversion rules.
+Conversely, whenever a number is used where a string is expected,
+the number is converted to a string, in a reasonable format.
+For complete control over how numbers are converted to strings,
+use the <code>format</code> function from the string library
+(see <a href="#pdf-string.format"><code>string.format</code></a>).
+
+
+
+
+
+
+
+<h2>2.3 - <a name="2.3">Variables</a></h2>
+
+<p>
+Variables are places that store values.
+
+There are three kinds of variables in Lua:
+global variables, local variables, and table fields.
+
+
+<p>
+A single name can denote a global variable or a local variable
+(or a function's formal parameter,
+which is a particular kind of local variable):
+
+<pre>
+	var ::= Name
+</pre><p>
+Name denotes identifiers, as defined in <a href="#2.1">&sect;2.1</a>.
+
+
+<p>
+Any variable is assumed to be global unless explicitly declared
+as a local (see <a href="#2.4.7">&sect;2.4.7</a>).
+Local variables are <em>lexically scoped</em>:
+local variables can be freely accessed by functions
+defined inside their scope (see <a href="#2.6">&sect;2.6</a>).
+
+
+<p>
+Before the first assignment to a variable, its value is <b>nil</b>.
+
+
+<p>
+Square brackets are used to index a table:
+
+<pre>
+	var ::= prefixexp `<b>[</b>&acute; exp `<b>]</b>&acute;
+</pre><p>
+The meaning of accesses to global variables 
+and table fields can be changed via metatables.
+An access to an indexed variable <code>t[i]</code> is equivalent to
+a call <code>gettable_event(t,i)</code>.
+(See <a href="#2.8">&sect;2.8</a> for a complete description of the
+<code>gettable_event</code> function.
+This function is not defined or callable in Lua.
+We use it here only for explanatory purposes.)
+
+
+<p>
+The syntax <code>var.Name</code> is just syntactic sugar for
+<code>var["Name"]</code>:
+
+<pre>
+	var ::= prefixexp `<b>.</b>&acute; Name
+</pre>
+
+<p>
+All global variables live as fields in ordinary Lua tables,
+called <em>environment tables</em> or simply
+<em>environments</em> (see <a href="#2.9">&sect;2.9</a>).
+Each function has its own reference to an environment,
+so that all global variables in this function
+will refer to this environment table.
+When a function is created,
+it inherits the environment from the function that created it.
+To get the environment table of a Lua function,
+you call <a href="#pdf-getfenv"><code>getfenv</code></a>.
+To replace it,
+you call <a href="#pdf-setfenv"><code>setfenv</code></a>.
+(You can only manipulate the environment of C&nbsp;functions
+through the debug library; (see <a href="#5.9">&sect;5.9</a>).)
+
+
+<p>
+An access to a global variable <code>x</code>
+is equivalent to <code>_env.x</code>,
+which in turn is equivalent to
+
+<pre>
+     gettable_event(_env, "x")
+</pre><p>
+where <code>_env</code> is the environment of the running function.
+(See <a href="#2.8">&sect;2.8</a> for a complete description of the
+<code>gettable_event</code> function.
+This function is not defined or callable in Lua.
+Similarly, the <code>_env</code> variable is not defined in Lua.
+We use them here only for explanatory purposes.)
+
+
+
+
+
+<h2>2.4 - <a name="2.4">Statements</a></h2>
+
+<p>
+Lua supports an almost conventional set of statements,
+similar to those in Pascal or C.
+This set includes
+assignments, control structures, function calls,
+and variable declarations.
+
+
+
+<h3>2.4.1 - <a name="2.4.1">Chunks</a></h3>
+
+<p>
+The unit of execution of Lua is called a <em>chunk</em>.
+A chunk is simply a sequence of statements,
+which are executed sequentially.
+Each statement can be optionally followed by a semicolon:
+
+<pre>
+	chunk ::= {stat [`<b>;</b>&acute;]}
+</pre><p>
+There are no empty statements and thus '<code>;;</code>' is not legal.
+
+
+<p>
+Lua handles a chunk as the body of an anonymous function 
+with a variable number of arguments
+(see <a href="#2.5.9">&sect;2.5.9</a>).
+As such, chunks can define local variables,
+receive arguments, and return values.
+
+
+<p>
+A chunk can be stored in a file or in a string inside the host program.
+To execute a chunk,
+Lua first pre-compiles the chunk into instructions for a virtual machine,
+and then it executes the compiled code
+with an interpreter for the virtual machine.
+
+
+<p>
+Chunks can also be pre-compiled into binary form;
+see program <code>luac</code> for details.
+Programs in source and compiled forms are interchangeable;
+Lua automatically detects the file type and acts accordingly.
+
+
+
+
+
+
+<h3>2.4.2 - <a name="2.4.2">Blocks</a></h3><p>
+A block is a list of statements;
+syntactically, a block is the same as a chunk:
+
+<pre>
+	block ::= chunk
+</pre>
+
+<p>
+A block can be explicitly delimited to produce a single statement:
+
+<pre>
+	stat ::= <b>do</b> block <b>end</b>
+</pre><p>
+Explicit blocks are useful
+to control the scope of variable declarations.
+Explicit blocks are also sometimes used to
+add a <b>return</b> or <b>break</b> statement in the middle
+of another block (see <a href="#2.4.4">&sect;2.4.4</a>).
+
+
+
+
+
+<h3>2.4.3 - <a name="2.4.3">Assignment</a></h3>
+
+<p>
+Lua allows multiple assignments.
+Therefore, the syntax for assignment
+defines a list of variables on the left side
+and a list of expressions on the right side.
+The elements in both lists are separated by commas:
+
+<pre>
+	stat ::= varlist `<b>=</b>&acute; explist
+	varlist ::= var {`<b>,</b>&acute; var}
+	explist ::= exp {`<b>,</b>&acute; exp}
+</pre><p>
+Expressions are discussed in <a href="#2.5">&sect;2.5</a>.
+
+
+<p>
+Before the assignment,
+the list of values is <em>adjusted</em> to the length of
+the list of variables.
+If there are more values than needed,
+the excess values are thrown away.
+If there are fewer values than needed,
+the list is extended with as many  <b>nil</b>'s as needed.
+If the list of expressions ends with a function call,
+then all values returned by that call enter the list of values,
+before the adjustment
+(except when the call is enclosed in parentheses; see <a href="#2.5">&sect;2.5</a>).
+
+
+<p>
+The assignment statement first evaluates all its expressions
+and only then are the assignments performed.
+Thus the code
+
+<pre>
+     i = 3
+     i, a[i] = i+1, 20
+</pre><p>
+sets <code>a[3]</code> to 20, without affecting <code>a[4]</code>
+because the <code>i</code> in <code>a[i]</code> is evaluated (to 3)
+before it is assigned&nbsp;4.
+Similarly, the line
+
+<pre>
+     x, y = y, x
+</pre><p>
+exchanges the values of <code>x</code> and <code>y</code>,
+and
+
+<pre>
+     x, y, z = y, z, x
+</pre><p>
+cyclically permutes the values of <code>x</code>, <code>y</code>, and <code>z</code>.
+
+
+<p>
+The meaning of assignments to global variables
+and table fields can be changed via metatables.
+An assignment to an indexed variable <code>t[i] = val</code> is equivalent to
+<code>settable_event(t,i,val)</code>.
+(See <a href="#2.8">&sect;2.8</a> for a complete description of the
+<code>settable_event</code> function.
+This function is not defined or callable in Lua.
+We use it here only for explanatory purposes.)
+
+
+<p>
+An assignment to a global variable <code>x = val</code>
+is equivalent to the assignment
+<code>_env.x = val</code>,
+which in turn is equivalent to
+
+<pre>
+     settable_event(_env, "x", val)
+</pre><p>
+where <code>_env</code> is the environment of the running function.
+(The <code>_env</code> variable is not defined in Lua.
+We use it here only for explanatory purposes.)
+
+
+
+
+
+<h3>2.4.4 - <a name="2.4.4">Control Structures</a></h3><p>
+The control structures
+<b>if</b>, <b>while</b>, and <b>repeat</b> have the usual meaning and
+familiar syntax:
+
+
+
+
+<pre>
+	stat ::= <b>while</b> exp <b>do</b> block <b>end</b>
+	stat ::= <b>repeat</b> block <b>until</b> exp
+	stat ::= <b>if</b> exp <b>then</b> block {<b>elseif</b> exp <b>then</b> block} [<b>else</b> block] <b>end</b>
+</pre><p>
+Lua also has a <b>for</b> statement, in two flavors (see <a href="#2.4.5">&sect;2.4.5</a>).
+
+
+<p>
+The condition expression of a
+control structure can return any value.
+Both <b>false</b> and <b>nil</b> are considered false.
+All values different from <b>nil</b> and <b>false</b> are considered true
+(in particular, the number 0 and the empty string are also true).
+
+
+<p>
+In the <b>repeat</b>&ndash;<b>until</b> loop,
+the inner block does not end at the <b>until</b> keyword,
+but only after the condition.
+So, the condition can refer to local variables
+declared inside the loop block.
+
+
+<p>
+The <b>return</b> statement is used to return values
+from a function or a chunk (which is just a function).
+
+Functions and chunks can return more than one value,
+and so the syntax for the <b>return</b> statement is
+
+<pre>
+	stat ::= <b>return</b> [explist]
+</pre>
+
+<p>
+The <b>break</b> statement is used to terminate the execution of a
+<b>while</b>, <b>repeat</b>, or <b>for</b> loop,
+skipping to the next statement after the loop:
+
+
+<pre>
+	stat ::= <b>break</b>
+</pre><p>
+A <b>break</b> ends the innermost enclosing loop.
+
+
+<p>
+The <b>return</b> and <b>break</b>
+statements can only be written as the <em>last</em> statement of a block.
+If it is really necessary to <b>return</b> or <b>break</b> in the
+middle of a block,
+then an explicit inner block can be used,
+as in the idioms
+<code>do return end</code> and <code>do break end</code>,
+because now <b>return</b> and <b>break</b> are the last statements in
+their (inner) blocks.
+
+
+
+
+
+<h3>2.4.5 - <a name="2.4.5">For Statement</a></h3>
+
+<p>
+
+The <b>for</b> statement has two forms:
+one numeric and one generic.
+
+
+<p>
+The numeric <b>for</b> loop repeats a block of code while a
+control variable runs through an arithmetic progression.
+It has the following syntax:
+
+<pre>
+	stat ::= <b>for</b> Name `<b>=</b>&acute; exp `<b>,</b>&acute; exp [`<b>,</b>&acute; exp] <b>do</b> block <b>end</b>
+</pre><p>
+The <em>block</em> is repeated for <em>name</em> starting at the value of
+the first <em>exp</em>, until it passes the second <em>exp</em> by steps of the
+third <em>exp</em>.
+More precisely, a <b>for</b> statement like
+
+<pre>
+     for v = <em>e1</em>, <em>e2</em>, <em>e3</em> do <em>block</em> end
+</pre><p>
+is equivalent to the code:
+
+<pre>
+     do
+       local <em>var</em>, <em>limit</em>, <em>step</em> = tonumber(<em>e1</em>), tonumber(<em>e2</em>), tonumber(<em>e3</em>)
+       if not (<em>var</em> and <em>limit</em> and <em>step</em>) then error() end
+       while (<em>step</em> &gt; 0 and <em>var</em> &lt;= <em>limit</em>) or (<em>step</em> &lt;= 0 and <em>var</em> &gt;= <em>limit</em>) do
+         local v = <em>var</em>
+         <em>block</em>
+         <em>var</em> = <em>var</em> + <em>step</em>
+       end
+     end
+</pre><p>
+Note the following:
+
+<ul>
+
+<li>
+All three control expressions are evaluated only once,
+before the loop starts.
+They must all result in numbers.
+</li>
+
+<li>
+<code><em>var</em></code>, <code><em>limit</em></code>, and <code><em>step</em></code> are invisible variables.
+The names shown here are for explanatory purposes only.
+</li>
+
+<li>
+If the third expression (the step) is absent,
+then a step of&nbsp;1 is used.
+</li>
+
+<li>
+You can use <b>break</b> to exit a <b>for</b> loop.
+</li>
+
+<li>
+The loop variable <code>v</code> is local to the loop;
+you cannot use its value after the <b>for</b> ends or is broken.
+If you need this value,
+assign it to another variable before breaking or exiting the loop.
+</li>
+
+</ul>
+
+<p>
+The generic <b>for</b> statement works over functions,
+called <em>iterators</em>.
+On each iteration, the iterator function is called to produce a new value,
+stopping when this new value is <b>nil</b>.
+The generic <b>for</b> loop has the following syntax:
+
+<pre>
+	stat ::= <b>for</b> namelist <b>in</b> explist <b>do</b> block <b>end</b>
+	namelist ::= Name {`<b>,</b>&acute; Name}
+</pre><p>
+A <b>for</b> statement like
+
+<pre>
+     for <em>var_1</em>, &middot;&middot;&middot;, <em>var_n</em> in <em>explist</em> do <em>block</em> end
+</pre><p>
+is equivalent to the code:
+
+<pre>
+     do
+       local <em>f</em>, <em>s</em>, <em>var</em> = <em>explist</em>
+       while true do
+         local <em>var_1</em>, &middot;&middot;&middot;, <em>var_n</em> = <em>f</em>(<em>s</em>, <em>var</em>)
+         <em>var</em> = <em>var_1</em>
+         if <em>var</em> == nil then break end
+         <em>block</em>
+       end
+     end
+</pre><p>
+Note the following:
+
+<ul>
+
+<li>
+<code><em>explist</em></code> is evaluated only once.
+Its results are an <em>iterator</em> function,
+a <em>state</em>,
+and an initial value for the first <em>iterator variable</em>.
+</li>
+
+<li>
+<code><em>f</em></code>, <code><em>s</em></code>, and <code><em>var</em></code> are invisible variables.
+The names are here for explanatory purposes only.
+</li>
+
+<li>
+You can use <b>break</b> to exit a <b>for</b> loop.
+</li>
+
+<li>
+The loop variables <code><em>var_i</em></code> are local to the loop;
+you cannot use their values after the <b>for</b> ends.
+If you need these values,
+then assign them to other variables before breaking or exiting the loop.
+</li>
+
+</ul>
+
+
+
+
+<h3>2.4.6 - <a name="2.4.6">Function Calls as Statements</a></h3><p>
+To allow possible side-effects,
+function calls can be executed as statements:
+
+<pre>
+	stat ::= functioncall
+</pre><p>
+In this case, all returned values are thrown away.
+Function calls are explained in <a href="#2.5.8">&sect;2.5.8</a>.
+
+
+
+
+
+<h3>2.4.7 - <a name="2.4.7">Local Declarations</a></h3><p>
+Local variables can be declared anywhere inside a block.
+The declaration can include an initial assignment:
+
+<pre>
+	stat ::= <b>local</b> namelist [`<b>=</b>&acute; explist]
+</pre><p>
+If present, an initial assignment has the same semantics
+of a multiple assignment (see <a href="#2.4.3">&sect;2.4.3</a>).
+Otherwise, all variables are initialized with <b>nil</b>.
+
+
+<p>
+A chunk is also a block (see <a href="#2.4.1">&sect;2.4.1</a>),
+and so local variables can be declared in a chunk outside any explicit block.
+The scope of such local variables extends until the end of the chunk.
+
+
+<p>
+The visibility rules for local variables are explained in <a href="#2.6">&sect;2.6</a>.
+
+
+

+
+
+<h2>2.5 - <a name="2.5">Expressions</a></h2>
+
+<p>
+The basic expressions in Lua are the following:
+
+<pre>
+	exp ::= prefixexp
+	exp ::= <b>nil</b> | <b>false</b> | <b>true</b>
+	exp ::= Number
+	exp ::= String
+	exp ::= function
+	exp ::= tableconstructor
+	exp ::= `<b>...</b>&acute;
+	exp ::= exp binop exp
+	exp ::= unop exp
+	prefixexp ::= var | functioncall | `<b>(</b>&acute; exp `<b>)</b>&acute;
+</pre>
+
+<p>
+Numbers and literal strings are explained in <a href="#2.1">&sect;2.1</a>;
+variables are explained in <a href="#2.3">&sect;2.3</a>;
+function definitions are explained in <a href="#2.5.9">&sect;2.5.9</a>;
+function calls are explained in <a href="#2.5.8">&sect;2.5.8</a>;
+table constructors are explained in <a href="#2.5.7">&sect;2.5.7</a>.
+Vararg expressions,
+denoted by three dots ('<code>...</code>'), can only be used when
+directly inside a vararg function;
+they are explained in <a href="#2.5.9">&sect;2.5.9</a>.
+
+
+<p>
+Binary operators comprise arithmetic operators (see <a href="#2.5.1">&sect;2.5.1</a>),
+relational operators (see <a href="#2.5.2">&sect;2.5.2</a>), logical operators (see <a href="#2.5.3">&sect;2.5.3</a>),
+and the concatenation operator (see <a href="#2.5.4">&sect;2.5.4</a>).
+Unary operators comprise the unary minus (see <a href="#2.5.1">&sect;2.5.1</a>),
+the unary <b>not</b> (see <a href="#2.5.3">&sect;2.5.3</a>),
+and the unary <em>length operator</em> (see <a href="#2.5.5">&sect;2.5.5</a>).
+
+
+<p>
+Both function calls and vararg expressions can result in multiple values.
+If an expression is used as a statement
+(only possible for function calls (see <a href="#2.4.6">&sect;2.4.6</a>)),
+then its return list is adjusted to zero elements,
+thus discarding all returned values.
+If an expression is used as the last (or the only) element
+of a list of expressions,
+then no adjustment is made
+(unless the call is enclosed in parentheses).
+In all other contexts,
+Lua adjusts the result list to one element,
+discarding all values except the first one.
+
+
+<p>
+Here are some examples:
+
+<pre>
+     f()                -- adjusted to 0 results
+     g(f(), x)          -- f() is adjusted to 1 result
+     g(x, f())          -- g gets x plus all results from f()
+     a,b,c = f(), x     -- f() is adjusted to 1 result (c gets nil)
+     a,b = ...          -- a gets the first vararg parameter, b gets
+                        -- the second (both a and b can get nil if there
+                        -- is no corresponding vararg parameter)
+     
+     a,b,c = x, f()     -- f() is adjusted to 2 results
+     a,b,c = f()        -- f() is adjusted to 3 results
+     return f()         -- returns all results from f()
+     return ...         -- returns all received vararg parameters
+     return x,y,f()     -- returns x, y, and all results from f()
+     {f()}              -- creates a list with all results from f()
+     {...}              -- creates a list with all vararg parameters
+     {f(), nil}         -- f() is adjusted to 1 result
+</pre>
+
+<p>
+Any expression enclosed in parentheses always results in only one value.
+Thus,
+<code>(f(x,y,z))</code> is always a single value,
+even if <code>f</code> returns several values.
+(The value of <code>(f(x,y,z))</code> is the first value returned by <code>f</code>
+or <b>nil</b> if <code>f</code> does not return any values.)
+
+
+
+<h3>2.5.1 - <a name="2.5.1">Arithmetic Operators</a></h3><p>
+Lua supports the usual arithmetic operators:
+the binary <code>+</code> (addition),
+<code>-</code> (subtraction), <code>*</code> (multiplication),
+<code>/</code> (division), <code>%</code> (modulo), and <code>^</code> (exponentiation);
+and unary <code>-</code> (negation).
+If the operands are numbers, or strings that can be converted to
+numbers (see <a href="#2.2.1">&sect;2.2.1</a>),
+then all operations have the usual meaning.
+Exponentiation works for any exponent.
+For instance, <code>x^(-0.5)</code> computes the inverse of the square root of <code>x</code>.
+Modulo is defined as
+
+<pre>
+     a % b == a - math.floor(a/b)*b
+</pre><p>
+That is, it is the remainder of a division that rounds
+the quotient towards minus infinity.
+
+
+
+
+
+<h3>2.5.2 - <a name="2.5.2">Relational Operators</a></h3><p>
+The relational operators in Lua are
+
+<pre>
+     ==    ~=    &lt;     &gt;     &lt;=    &gt;=
+</pre><p>
+These operators always result in <b>false</b> or <b>true</b>.
+
+
+<p>
+Equality (<code>==</code>) first compares the type of its operands.
+If the types are different, then the result is <b>false</b>.
+Otherwise, the values of the operands are compared.
+Numbers and strings are compared in the usual way.
+Objects (tables, userdata, threads, and functions)
+are compared by <em>reference</em>:
+two objects are considered equal only if they are the <em>same</em> object.
+Every time you create a new object
+(a table, userdata, thread, or function),
+this new object is different from any previously existing object.
+
+
+<p>
+You can change the way that Lua compares tables and userdata 
+by using the "eq" metamethod (see <a href="#2.8">&sect;2.8</a>).
+
+
+<p>
+The conversion rules of <a href="#2.2.1">&sect;2.2.1</a>
+<em>do not</em> apply to equality comparisons.
+Thus, <code>"0"==0</code> evaluates to <b>false</b>,
+and <code>t[0]</code> and <code>t["0"]</code> denote different
+entries in a table.
+
+
+<p>
+The operator <code>~=</code> is exactly the negation of equality (<code>==</code>).
+
+
+<p>
+The order operators work as follows.
+If both arguments are numbers, then they are compared as such.
+Otherwise, if both arguments are strings,
+then their values are compared according to the current locale.
+Otherwise, Lua tries to call the "lt" or the "le"
+metamethod (see <a href="#2.8">&sect;2.8</a>).
+A comparison <code>a &gt; b</code> is translated to <code>b &lt; a</code>
+and <code>a &gt;= b</code> is translated to <code>b &lt;= a</code>.
+
+
+
+
+
+<h3>2.5.3 - <a name="2.5.3">Logical Operators</a></h3><p>
+The logical operators in Lua are
+<b>and</b>, <b>or</b>, and <b>not</b>.
+Like the control structures (see <a href="#2.4.4">&sect;2.4.4</a>),
+all logical operators consider both <b>false</b> and <b>nil</b> as false
+and anything else as true.
+
+
+<p>
+The negation operator <b>not</b> always returns <b>false</b> or <b>true</b>.
+The conjunction operator <b>and</b> returns its first argument
+if this value is <b>false</b> or <b>nil</b>;
+otherwise, <b>and</b> returns its second argument.
+The disjunction operator <b>or</b> returns its first argument
+if this value is different from <b>nil</b> and <b>false</b>;
+otherwise, <b>or</b> returns its second argument.
+Both <b>and</b> and <b>or</b> use short-cut evaluation;
+that is,
+the second operand is evaluated only if necessary.
+Here are some examples:
+
+<pre>
+     10 or 20            --&gt; 10
+     10 or error()       --&gt; 10
+     nil or "a"          --&gt; "a"
+     nil and 10          --&gt; nil
+     false and error()   --&gt; false
+     false and nil       --&gt; false
+     false or nil        --&gt; nil
+     10 and 20           --&gt; 20
+</pre><p>
+(In this manual,
+<code>--&gt;</code> indicates the result of the preceding expression.)
+
+
+
+
+
+<h3>2.5.4 - <a name="2.5.4">Concatenation</a></h3><p>
+The string concatenation operator in Lua is
+denoted by two dots ('<code>..</code>').
+If both operands are strings or numbers, then they are converted to
+strings according to the rules mentioned in <a href="#2.2.1">&sect;2.2.1</a>.
+Otherwise, the "concat" metamethod is called (see <a href="#2.8">&sect;2.8</a>).
+
+
+
+
+
+<h3>2.5.5 - <a name="2.5.5">The Length Operator</a></h3>
+
+<p>
+The length operator is denoted by the unary operator <code>#</code>.
+The length of a string is its number of bytes
+(that is, the usual meaning of string length when each
+character is one byte).
+
+
+<p>
+The length of a table <code>t</code> is defined to be any
+integer index <code>n</code>
+such that <code>t[n]</code> is not <b>nil</b> and <code>t[n+1]</code> is <b>nil</b>;
+moreover, if <code>t[1]</code> is <b>nil</b>, <code>n</code> can be zero.
+For a regular array, with non-nil values from 1 to a given <code>n</code>,
+its length is exactly that <code>n</code>,
+the index of its last value.
+If the array has "holes"
+(that is, <b>nil</b> values between other non-nil values),
+then <code>#t</code> can be any of the indices that
+directly precedes a <b>nil</b> value
+(that is, it may consider any such <b>nil</b> value as the end of
+the array). 
+
+
+
+
+
+<h3>2.5.6 - <a name="2.5.6">Precedence</a></h3><p>
+Operator precedence in Lua follows the table below,
+from lower to higher priority:
+
+<pre>
+     or
+     and
+     &lt;     &gt;     &lt;=    &gt;=    ~=    ==
+     ..
+     +     -
+     *     /     %
+     not   #     - (unary)
+     ^
+</pre><p>
+As usual,
+you can use parentheses to change the precedences of an expression.
+The concatenation ('<code>..</code>') and exponentiation ('<code>^</code>')
+operators are right associative.
+All other binary operators are left associative.
+
+
+
+
+
+<h3>2.5.7 - <a name="2.5.7">Table Constructors</a></h3><p>
+Table constructors are expressions that create tables.
+Every time a constructor is evaluated, a new table is created.
+A constructor can be used to create an empty table
+or to create a table and initialize some of its fields.
+The general syntax for constructors is
+
+<pre>
+	tableconstructor ::= `<b>{</b>&acute; [fieldlist] `<b>}</b>&acute;
+	fieldlist ::= field {fieldsep field} [fieldsep]
+	field ::= `<b>[</b>&acute; exp `<b>]</b>&acute; `<b>=</b>&acute; exp | Name `<b>=</b>&acute; exp | exp
+	fieldsep ::= `<b>,</b>&acute; | `<b>;</b>&acute;
+</pre>
+
+<p>
+Each field of the form <code>[exp1] = exp2</code> adds to the new table an entry
+with key <code>exp1</code> and value <code>exp2</code>.
+A field of the form <code>name = exp</code> is equivalent to
+<code>["name"] = exp</code>.
+Finally, fields of the form <code>exp</code> are equivalent to
+<code>[i] = exp</code>, where <code>i</code> are consecutive numerical integers,
+starting with 1.
+Fields in the other formats do not affect this counting.
+For example,
+
+<pre>
+     a = { [f(1)] = g; "x", "y"; x = 1, f(x), [30] = 23; 45 }
+</pre><p>
+is equivalent to
+
+<pre>
+     do
+       local t = {}
+       t[f(1)] = g

+
+<p>
+If the last field in the list has the form <code>exp</code>
+and the expression is a function call or a vararg expression,
+then all values returned by this expression enter the list consecutively
+(see <a href="#2.5.8">&sect;2.5.8</a>).
+To avoid this,
+enclose the function call or the vararg expression
+in parentheses (see <a href="#2.5">&sect;2.5</a>).

+The field list can have an optional trailing separator,
+as a convenience for machine-generated code.

+<h3>2.5.8 - <a name="2.5.8">Function Calls</a></h3><p>
+A function call in Lua has the following syntax:
+
+<pre>
+	functioncall ::= prefixexp args
+</pre><p>
+In a function call,
+first prefixexp and args are evaluated.
+If the value of prefixexp has type <em>function</em>,
+then this function is called
+with the given arguments.
+Otherwise, the prefixexp "call" metamethod is called,
+having as first parameter the value of prefixexp,
+followed by the original call arguments
+(see <a href="#2.8">&sect;2.8</a>).
+
+
+<p>
+The form
+
+<pre>
+	functioncall ::= prefixexp `<b>:</b>&acute; Name args
+</pre><p>
+can be used to call "methods".
+A call <code>v:name(<em>args</em>)</code>
+is syntactic sugar for <code>v.name(v,<em>args</em>)</code>,
+except that <code>v</code> is evaluated only once.
+
+
+<p>
+Arguments have the following syntax:
+
+<pre>
+	args ::= `<b>(</b>&acute; [explist] `<b>)</b>&acute;
+	args ::= tableconstructor
+	args ::= String
+</pre><p>
+All argument expressions are evaluated before the call.
+A call of the form <code>f{<em>fields</em>}</code> is
+syntactic sugar for <code>f({<em>fields</em>})</code>;
+that is, the argument list is a single new table.
+A call of the form <code>f'<em>string</em>'</code>
+(or <code>f"<em>string</em>"</code> or <code>f[[<em>string</em>]]</code>)
+is syntactic sugar for <code>f('<em>string</em>')</code>;
+that is, the argument list is a single literal string.
+
+
+<p>
+As an exception to the free-format syntax of Lua,
+you cannot put a line break before the '<code>(</code>' in a function call.
+This restriction avoids some ambiguities in the language.
+If you write
+
+<pre>
+     a = f
+     (g).x(a)
+</pre><p>
+Lua would see that as a single statement, <code>a = f(g).x(a)</code>.
+So, if you want two statements, you must add a semi-colon between them.
+If you actually want to call <code>f</code>,
+you must remove the line break before <code>(g)</code>.
+
+
+<p>
+A call of the form <code>return</code> <em>functioncall</em> is called
+a <em>tail call</em>.
+Lua implements <em>proper tail calls</em>
+(or <em>proper tail recursion</em>):
+in a tail call,
+the called function reuses the stack entry of the calling function.
+Therefore, there is no limit on the number of nested tail calls that
+a program can execute.
+However, a tail call erases any debug information about the
+calling function.
+Note that a tail call only happens with a particular syntax,
+where the <b>return</b> has one single function call as argument;
+this syntax makes the calling function return exactly
+the returns of the called function.
+So, none of the following examples are tail calls:
+
+<pre>
+     return (f(x))        -- results adjusted to 1
+     return 2 * f(x)
+     return x, f(x)       -- additional results
+     f(x); return         -- results discarded
+     return x or f(x)     -- results adjusted to 1
+</pre>
+
+
+
+
+<h3>2.5.9 - <a name="2.5.9">Function Definitions</a></h3>
+
+<p>
+The syntax for function definition is
+
+<pre>
+	function ::= <b>function</b> funcbody
+	funcbody ::= `<b>(</b>&acute; [parlist] `<b>)</b>&acute; block <b>end</b>
+</pre>
+
+<p>
+The following syntactic sugar simplifies function definitions:
+
+<pre>
+	stat ::= <b>function</b> funcname funcbody
+	stat ::= <b>local</b> <b>function</b> Name funcbody
+	funcname ::= Name {`<b>.</b>&acute; Name} [`<b>:</b>&acute; Name]
+</pre><p>
+The statement
+
+<pre>
+     function f () <em>body</em> end
+</pre><p>
+translates to
+
+<pre>
+     f = function () <em>body</em> end
+</pre><p>
+The statement
+
+<pre>
+     function t.a.b.c.f () <em>body</em> end
+</pre><p>
+translates to
+
+<pre>
+     t.a.b.c.f = function () <em>body</em> end
+</pre><p>
+The statement
+
+<pre>
+     local function f () <em>body</em> end
+</pre><p>
+translates to
+
+<pre>
+     local f; f = function () <em>body</em> end
+</pre><p>
+<em>not</em> to
+
+<pre>
+     local f = function () <em>body</em> end
+</pre><p>
+(This only makes a difference when the body of the function
+contains references to <code>f</code>.)
+
+
+<p>
+A function definition is an executable expression,
+whose value has type <em>function</em>.
+When Lua pre-compiles a chunk,
+all its function bodies are pre-compiled too.
+Then, whenever Lua executes the function definition,
+the function is <em>instantiated</em> (or <em>closed</em>).
+This function instance (or <em>closure</em>)
+is the final value of the expression.
+Different instances of the same function
+can refer to different  external local variables
+and can have different environment tables.
+
+
+<p>
+Parameters act as local variables that are
+initialized with the argument values:
+
+<pre>
+	parlist ::= namelist [`<b>,</b>&acute; `<b>...</b>&acute;] | `<b>...</b>&acute;
+</pre><p>
+When a function is called,
+the list of arguments is adjusted to
+the length of the list of parameters,
+unless the function is a variadic or <em>vararg function</em>,
+which is
+indicated by three dots ('<code>...</code>') at the end of its parameter list.
+A vararg function does not adjust its argument list;
+instead, it collects all extra arguments and supplies them
+to the function through a <em>vararg expression</em>,
+which is also written as three dots.
+The value of this expression is a list of all actual extra arguments,
+similar to a function with multiple results.
+If a vararg expression is used inside another expression
+or in the middle of a list of expressions,
+then its return list is adjusted to one element.
+If the expression is used as the last element of a list of expressions,
+then no adjustment is made
+(unless that last expression is enclosed in parentheses).
+
+
+<p>
+As an example, consider the following definitions:
+
+<pre>
+     function f(a, b) end
+     function g(a, b, ...) end
+     function r() return 1,2,3 end
+</pre><p>
+Then, we have the following mapping from arguments to parameters and
+to the vararg expression:
+
+<pre>
+     CALL            PARAMETERS
+     
+     f(3)             a=3, b=nil
+     f(3, 4)          a=3, b=4
+     f(3, 4, 5)       a=3, b=4
+     f(r(), 10)       a=1, b=10
+     f(r())           a=1, b=2
+     
+     g(3)             a=3, b=nil, ... --&gt;  (nothing)
+     g(3, 4)          a=3, b=4,   ... --&gt;  (nothing)
+     g(3, 4, 5, 8)    a=3, b=4,   ... --&gt;  5  8
+     g(5, r())        a=5, b=1,   ... --&gt;  2  3
+</pre>
+
+<p>
+Results are returned using the <b>return</b> statement (see <a href="#2.4.4">&sect;2.4.4</a>).
+If control reaches the end of a function
+without encountering a <b>return</b> statement,
+then the function returns with no results.
+
+
+<p>
+The <em>colon</em> syntax
+is used for defining <em>methods</em>,
+that is, functions that have an implicit extra parameter <code>self</code>.
+Thus, the statement
+
+<pre>
+     function t.a.b.c:f (<em>params</em>) <em>body</em> end
+</pre><p>
+is syntactic sugar for
+
+<pre>
+     t.a.b.c.f = function (self, <em>params</em>) <em>body</em> end
+</pre>
+
+
+
+
+
+
+<h2>2.6 - <a name="2.6">Visibility Rules</a></h2>
+
+<p>
+
+Lua is a lexically scoped language.
+The scope of variables begins at the first statement <em>after</em>
+their declaration and lasts until the end of the innermost block that
+includes the declaration.
+Consider the following example:
+
+<pre>
+     x = 10                -- global variable
+     do                    -- new block
+       local x = x         -- new 'x', with value 10
+       print(x)            --&gt; 10
+       x = x+1
+       do                  -- another block
+         local x = x+1     -- another 'x'
+         print(x)          --&gt; 12
+       end
+       print(x)            --&gt; 11
+     end
+     print(x)              --&gt; 10  (the global one)
+</pre>
+
+<p>
+Notice that, in a declaration like <code>local x = x</code>,
+the new <code>x</code> being declared is not in scope yet,
+and so the second <code>x</code> refers to the outside variable.
+
+
+<p>
+Because of the lexical scoping rules,
+local variables can be freely accessed by functions
+defined inside their scope.
+A local variable used by an inner function is called
+an <em>upvalue</em>, or <em>external local variable</em>,
+inside the inner function.
+
+
+<p>
+Notice that each execution of a <b>local</b> statement
+defines new local variables.
+Consider the following example:
+
+<pre>
+     a = {}
+     local x = 20
+     for i=1,10 do
+       local y = 0
+       a[i] = function () y=y+1; return x+y end
+     end
+</pre><p>
+The loop creates ten closures
+(that is, ten instances of the anonymous function).
+Each of these closures uses a different <code>y</code> variable,
+while all of them share the same <code>x</code>.
+
+
+
+
+
+<h2>2.7 - <a name="2.7">Error Handling</a></h2>
+
+<p>
+Because Lua is an embedded extension language,
+all Lua actions start from C&nbsp;code in the host program
+calling a function from the Lua library (see <a href="#lua_pcall"><code>lua_pcall</code></a>).
+Whenever an error occurs during Lua compilation or execution,
+control returns to C,
+which can take appropriate measures
+(such as printing an error message).
+
+
+<p>
+Lua code can explicitly generate an error by calling the
+<a href="#pdf-error"><code>error</code></a> function.
+If you need to catch errors in Lua,
+you can use the <a href="#pdf-pcall"><code>pcall</code></a> function.
+
+
+
+
+
+<h2>2.8 - <a name="2.8">Metatables</a></h2>
+
+<p>
+Every value in Lua can have a <em>metatable</em>.
+This <em>metatable</em> is an ordinary Lua table
+that defines the behavior of the original value
+under certain special operations.
+You can change several aspects of the behavior
+of operations over a value by setting specific fields in its metatable.
+For instance, when a non-numeric value is the operand of an addition,
+Lua checks for a function in the field <code>"__add"</code> in its metatable.
+If it finds one,
+Lua calls this function to perform the addition.
+
+
+<p>
+We call the keys in a metatable <em>events</em>
+and the values <em>metamethods</em>.
+In the previous example, the event is <code>"add"</code> 
+and the metamethod is the function that performs the addition.
+
+
+<p>
+You can query the metatable of any value
+through the <a href="#pdf-getmetatable"><code>getmetatable</code></a> function.
+
+
+<p>
+You can replace the metatable of tables
+through the <a href="#pdf-setmetatable"><code>setmetatable</code></a>
+function.
+You cannot change the metatable of other types from Lua
+(except by using the debug library);
+you must use the C&nbsp;API for that.
+
+
+<p>
+Tables and full userdata have individual metatables
+(although multiple tables and userdata can share their metatables).
+Values of all other types share one single metatable per type;
+that is, there is one single metatable for all numbers,
+one for all strings, etc.
+
+
+<p>
+A metatable controls how an object behaves in arithmetic operations,
+order comparisons, concatenation, length operation, and indexing.
+A metatable also can define a function to be called when a userdata
+is garbage collected.
+For each of these operations Lua associates a specific key
+called an <em>event</em>.
+When Lua performs one of these operations over a value,
+it checks whether this value has a metatable with the corresponding event.
+If so, the value associated with that key (the metamethod)
+controls how Lua will perform the operation.
+
+
+<p>
+Metatables control the operations listed next.
+Each operation is identified by its corresponding name.
+The key for each operation is a string with its name prefixed by
+two underscores, '<code>__</code>';
+for instance, the key for operation "add" is the
+string <code>"__add"</code>.
+The semantics of these operations is better explained by a Lua function
+describing how the interpreter executes the operation.
+
+
+<p>
+The code shown here in Lua is only illustrative;
+the real behavior is hard coded in the interpreter
+and it is much more efficient than this simulation.
+All functions used in these descriptions
+(<a href="#pdf-rawget"><code>rawget</code></a>, <a href="#pdf-tonumber"><code>tonumber</code></a>, etc.)
+are described in <a href="#5.1">&sect;5.1</a>.
+In particular, to retrieve the metamethod of a given object,
+we use the expression
+
+<pre>
+     metatable(obj)[event]
+</pre><p>
+This should be read as
+
+<pre>
+     rawget(getmetatable(obj) or {}, event)
+</pre><p>
+
+That is, the access to a metamethod does not invoke other metamethods,
+and the access to objects with no metatables does not fail
+(it simply results in <b>nil</b>).
+
+
+
+<ul>
+
+<li><b>"add":</b>
+the <code>+</code> operation.
+
+
+
+<p>
+The function <code>getbinhandler</code> below defines how Lua chooses a handler
+for a binary operation.
+First, Lua tries the first operand.
+If its type does not define a handler for the operation,
+then Lua tries the second operand.
+

+<h2>2.9 - <a name="2.9">Environments</a></h2>
+
+<p>
+Besides metatables,
+objects of types thread, function, and userdata
+have another table associated with them,
+called their <em>environment</em>.
+Like metatables, environments are regular tables and
+multiple objects can share the same environment.
+
+
+<p>
+Threads are created sharing the environment of the creating thread.
+Userdata and C&nbsp;functions are created sharing the environment
+of the creating C&nbsp;function.
+Non-nested Lua functions
+(created by <a href="#pdf-loadfile"><code>loadfile</code></a>, <a href="#pdf-loadstring"><code>loadstring</code></a> or <a href="#pdf-load"><code>load</code></a>)
+are created sharing the environment of the creating thread.
+Nested Lua functions are created sharing the environment of
+the creating Lua function.
+
+
+<p>
+Environments associated with userdata have no meaning for Lua.
+It is only a convenience feature for programmers to associate a table to
+a userdata.
+
+
+<p>
+Environments associated with threads are called
+<em>global environments</em>.
+They are used as the default environment for threads and
+non-nested Lua functions created by the thread
+and can be directly accessed by C&nbsp;code (see <a href="#3.3">&sect;3.3</a>).
+
+
+<p>
+The environment associated with a C&nbsp;function can be directly
+accessed by C&nbsp;code (see <a href="#3.3">&sect;3.3</a>).
+It is used as the default environment for other C&nbsp;functions
+and userdata created by the function.
+
+
+<p>
+Environments associated with Lua functions are used to resolve
+all accesses to global variables within the function (see <a href="#2.3">&sect;2.3</a>).
+They are used as the default environment for nested Lua functions
+created by the function.
+
+
+<p>
+You can change the environment of a Lua function or the
+running thread by calling <a href="#pdf-setfenv"><code>setfenv</code></a>.
+You can get the environment of a Lua function or the running thread
+by calling <a href="#pdf-getfenv"><code>getfenv</code></a>.
+To manipulate the environment of other objects
+(userdata, C&nbsp;functions, other threads) you must
+use the C&nbsp;API.
+
+
+
+
+
+<h2>2.10 - <a name="2.10">Garbage Collection</a></h2>
+
+<p>
+Lua performs automatic memory management.
+This means that
+you have to worry neither about allocating memory for new objects
+nor about freeing it when the objects are no longer needed.
+Lua manages memory automatically by running
+a <em>garbage collector</em> from time to time
+to collect all <em>dead objects</em>
+(that is, objects that are no longer accessible from Lua).
+All memory used by Lua is subject to automatic management:
+tables, userdata, functions, threads, strings, etc.
+
+
+<p>
+Lua implements an incremental mark-and-sweep collector.
+It uses two numbers to control its garbage-collection cycles:
+the <em>garbage-collector pause</em> and
+the <em>garbage-collector step multiplier</em>.
+Both use percentage points as units
+(so that a value of 100 means an internal value of 1).
+
+
+<p>
+The garbage-collector pause
+controls how long the collector waits before starting a new cycle.
+Larger values make the collector less aggressive.
+Values smaller than 100 mean the collector will not wait to
+start a new cycle.
+A value of 200 means that the collector waits for the total memory in use
+to double before starting a new cycle.
+
+
+<p>
+The step multiplier
+controls the relative speed of the collector relative to
+memory allocation.
+Larger values make the collector more aggressive but also increase
+the size of each incremental step.
+Values smaller than 100 make the collector too slow and
+can result in the collector never finishing a cycle.
+The default, 200, means that the collector runs at "twice"
+the speed of memory allocation.
+
+
+<p>
+You can change these numbers by calling <a href="#lua_gc"><code>lua_gc</code></a> in C
+or <a href="#pdf-collectgarbage"><code>collectgarbage</code></a> in Lua.
+With these functions you can also control 
+the collector directly (e.g., stop and restart it).
+
+
+
+<h3>2.10.1 - <a name="2.10.1">Garbage-Collection Metamethods</a></h3>
+
+<p>
+Using the C&nbsp;API,
+you can set garbage-collector metamethods for userdata (see <a href="#2.8">&sect;2.8</a>).
+These metamethods are also called <em>finalizers</em>.
+Finalizers allow you to coordinate Lua's garbage collection
+with external resource management
+(such as closing files, network or database connections,
+or freeing your own memory).
+
+
+<p>
+Garbage userdata with a field <code>__gc</code> in their metatables are not
+collected immediately by the garbage collector.
+Instead, Lua puts them in a list.
+After the collection,
+Lua does the equivalent of the following function
+for each userdata in that list:
+
+<pre>
+     function gc_event (udata)
+       local h = metatable(udata).__gc
+       if h then
+         h(udata)
+       end
+     end
+</pre>
+
+<p>
+At the end of each garbage-collection cycle,
+the finalizers for userdata are called in <em>reverse</em>
+order of their creation,
+among those collected in that cycle.
+That is, the first finalizer to be called is the one associated
+with the userdata created last in the program.
+The userdata itself is freed only in the next garbage-collection cycle.
+
+
+
+
+
+<h3>2.10.2 - <a name="2.10.2">Weak Tables</a></h3>
+
+<p>
+A <em>weak table</em> is a table whose elements are
+<em>weak references</em>.
+A weak reference is ignored by the garbage collector.
+In other words,
+if the only references to an object are weak references,
+then the garbage collector will collect this object.
+
+
+<p>
+A weak table can have weak keys, weak values, or both.
+A table with weak keys allows the collection of its keys,
+but prevents the collection of its values.
+A table with both weak keys and weak values allows the collection of
+both keys and values.
+In any case, if either the key or the value is collected,
+the whole pair is removed from the table.
+The weakness of a table is controlled by the
+<code>__mode</code> field of its metatable.
+If the <code>__mode</code> field is a string containing the character&nbsp;'<code>k</code>',
+the keys in the table are weak.
+If <code>__mode</code> contains '<code>v</code>',
+the values in the table are weak.
+
+
+<p>
+After you use a table as a metatable,
+you should not change the value of its <code>__mode</code> field.
+Otherwise, the weak behavior of the tables controlled by this
+metatable is undefined.
+
+
+
+
+
+
+
+<h2>2.11 - <a name="2.11">Coroutines</a></h2>
+
+<p>
+Lua supports coroutines,
+also called <em>collaborative multithreading</em>.
+A coroutine in Lua represents an independent thread of execution.
+Unlike threads in multithread systems, however,
+a coroutine only suspends its execution by explicitly calling
+a yield function.
+
+
+<p>
+You create a coroutine with a call to <a href="#pdf-coroutine.create"><code>coroutine.create</code></a>.
+Its sole argument is a function
+that is the main function of the coroutine.
+The <code>create</code> function only creates a new coroutine and
+returns a handle to it (an object of type <em>thread</em>);
+it does not start the coroutine execution.
+
+
+<p>
+When you first call <a href="#pdf-coroutine.resume"><code>coroutine.resume</code></a>,
+passing as its first argument
+a thread returned by <a href="#pdf-coroutine.create"><code>coroutine.create</code></a>,
+the coroutine starts its execution,
+at the first line of its main function.
+Extra arguments passed to <a href="#pdf-coroutine.resume"><code>coroutine.resume</code></a> are passed on
+to the coroutine main function.
+After the coroutine starts running,
+it runs until it terminates or <em>yields</em>.
+
+
+<p>
+A coroutine can terminate its execution in two ways:
+normally, when its main function returns
+(explicitly or implicitly, after the last instruction);
+and abnormally, if there is an unprotected error.
+In the first case, <a href="#pdf-coroutine.resume"><code>coroutine.resume</code></a> returns <b>true</b>,
+plus any values returned by the coroutine main function.
+In case of errors, <a href="#pdf-coroutine.resume"><code>coroutine.resume</code></a> returns <b>false</b>
+plus an error message.
+
+
+<p>
+A coroutine yields by calling <a href="#pdf-coroutine.yield"><code>coroutine.yield</code></a>.
+When a coroutine yields,
+the corresponding <a href="#pdf-coroutine.resume"><code>coroutine.resume</code></a> returns immediately,
+even if the yield happens inside nested function calls
+(that is, not in the main function,
+but in a function directly or indirectly called by the main function).
+In the case of a yield, <a href="#pdf-coroutine.resume"><code>coroutine.resume</code></a> also returns <b>true</b>,
+plus any values passed to <a href="#pdf-coroutine.yield"><code>coroutine.yield</code></a>.
+The next time you resume the same coroutine,
+it continues its execution from the point where it yielded,
+with the call to <a href="#pdf-coroutine.yield"><code>coroutine.yield</code></a> returning any extra
+arguments passed to <a href="#pdf-coroutine.resume"><code>coroutine.resume</code></a>.
+
+
+<p>
+Like <a href="#pdf-coroutine.create"><code>coroutine.create</code></a>,
+the <a href="#pdf-coroutine.wrap"><code>coroutine.wrap</code></a> function also creates a coroutine,
+but instead of returning the coroutine itself,
+it returns a function that, when called, resumes the coroutine.
+Any arguments passed to this function
+go as extra arguments to <a href="#pdf-coroutine.resume"><code>coroutine.resume</code></a>.
+<a href="#pdf-coroutine.wrap"><code>coroutine.wrap</code></a> returns all the values returned by <a href="#pdf-coroutine.resume"><code>coroutine.resume</code></a>,
+except the first one (the boolean error code).
+Unlike <a href="#pdf-coroutine.resume"><code>coroutine.resume</code></a>,
+<a href="#pdf-coroutine.wrap"><code>coroutine.wrap</code></a> does not catch errors;
+any error is propagated to the caller.
+
+
+<p>
+As an example,
+consider the following code:
+
+<pre>
+     function foo (a)
+       print("foo", a)
+       return coroutine.yield(2*a)
+     end
+     
+     co = coroutine.create(function (a,b)
+           print("co-body", a, b)
+           local r = foo(a+1)
+           print("co-body", r)
+           local r, s = coroutine.yield(a+b, a-b)
+           print("co-body", r, s)
+           return b, "end"
+     end)
+            
+     print("main", coroutine.resume(co, 1, 10))
+     print("main", coroutine.resume(co, "r"))
+     print("main", coroutine.resume(co, "x", "y"))
+     print("main", coroutine.resume(co, "x", "y"))
+</pre><p>
+When you run it, it produces the following output:
+
+<pre>
+     co-body 1       10
+     foo     2
+     
+     main    true    4
+     co-body r
+     main    true    11      -9
+     co-body x       y
+     main    true    10      end
+     main    false   cannot resume dead coroutine
+</pre>

+
+<h1>3 - <a name="3">The Application Program Interface</a></h1>
+
+<p>
+
+This section describes the C&nbsp;API for Lua, that is,
+the set of C&nbsp;functions available to the host program to communicate
+with Lua.
+All API functions and related types and constants
+are declared in the header file <a name="pdf-lua.h"><code>lua.h</code></a>.
+
+
+<p>
+Even when we use the term "function",
+any facility in the API may be provided as a macro instead.
+All such macros use each of their arguments exactly once
+(except for the first argument, which is always a Lua state),
+and so do not generate any hidden side-effects.
+
+
+<p>
+As in most C&nbsp;libraries,
+the Lua API functions do not check their arguments for validity or consistency.
+However, you can change this behavior by compiling Lua
+with a proper definition for the macro <a name="pdf-luai_apicheck"><code>luai_apicheck</code></a>,
+in file <code>luaconf.h</code>.
+
+
+
+<h2>3.1 - <a name="3.1">The Stack</a></h2>
+
+<p>
+Lua uses a <em>virtual stack</em> to pass values to and from C.
+Each element in this stack represents a Lua value
+(<b>nil</b>, number, string, etc.).
+
+
+<p>
+Whenever Lua calls C, the called function gets a new stack,
+which is independent of previous stacks and of stacks of
+C&nbsp;functions that are still active.
+This stack initially contains any arguments to the C&nbsp;function
+and it is where the C&nbsp;function pushes its results
+to be returned to the caller (see <a href="#lua_CFunction"><code>lua_CFunction</code></a>).
+
+
+<p>
+For convenience,
+most query operations in the API do not follow a strict stack discipline.
+Instead, they can refer to any element in the stack
+by using an <em>index</em>:
+A positive index represents an <em>absolute</em> stack position
+(starting at&nbsp;1);
+a negative index represents an <em>offset</em> relative to the top of the stack.
+More specifically, if the stack has <em>n</em> elements,
+then index&nbsp;1 represents the first element
+(that is, the element that was pushed onto the stack first)
+and
+index&nbsp;<em>n</em> represents the last element;
+index&nbsp;-1 also represents the last element
+(that is, the element at the&nbsp;top)
+and index <em>-n</em> represents the first element.
+We say that an index is <em>valid</em>
+if it lies between&nbsp;1 and the stack top
+(that is, if <code>1 &le; abs(index) &le; top</code>).
+ 
+
+
+
+
+
+<h2>3.2 - <a name="3.2">Stack Size</a></h2>
+
+<p>
+When you interact with Lua API,
+you are responsible for ensuring consistency.
+In particular,
+<em>you are responsible for controlling stack overflow</em>.
+You can use the function <a href="#lua_checkstack"><code>lua_checkstack</code></a>
+to grow the stack size.
+
+
+<p>
+Whenever Lua calls C,
+it ensures that at least <a name="pdf-LUA_MINSTACK"><code>LUA_MINSTACK</code></a> stack positions are available.
+<code>LUA_MINSTACK</code> is defined as 20,
+so that usually you do not have to worry about stack space
+unless your code has loops pushing elements onto the stack.
+
+
+<p>
+Most query functions accept as indices any value inside the
+available stack space, that is, indices up to the maximum stack size
+you have set through <a href="#lua_checkstack"><code>lua_checkstack</code></a>.
+Such indices are called <em>acceptable indices</em>.
+More formally, we define an <em>acceptable index</em>
+as follows:
+
+<pre>
+     (index &lt; 0 &amp;&amp; abs(index) &lt;= top) ||
+     (index &gt; 0 &amp;&amp; index &lt;= stackspace)
+</pre><p>
+Note that 0 is never an acceptable index.
+
+
+
+
+
+<h2>3.3 - <a name="3.3">Pseudo-Indices</a></h2>
+
+<p>
+Unless otherwise noted,
+any function that accepts valid indices can also be called with
+<em>pseudo-indices</em>,
+which represent some Lua values that are accessible to C&nbsp;code
+but which are not in the stack.
+Pseudo-indices are used to access the thread environment,
+the function environment,
+the registry,
+and the upvalues of a C&nbsp;function (see <a href="#3.4">&sect;3.4</a>).
+
+
+<p>
+The thread environment (where global variables live) is
+always at pseudo-index <a name="pdf-LUA_GLOBALSINDEX"><code>LUA_GLOBALSINDEX</code></a>.
+The environment of the running C&nbsp;function is always
+at pseudo-index <a name="pdf-LUA_ENVIRONINDEX"><code>LUA_ENVIRONINDEX</code></a>.
+
+
+<p>
+To access and change the value of global variables,
+you can use regular table operations over an environment table.
+For instance, to access the value of a global variable, do
+
+<pre>
+     lua_getfield(L, LUA_GLOBALSINDEX, varname);
+</pre>
+
+
+
+
+<h2>3.4 - <a name="3.4">C Closures</a></h2>
+
+<p>
+When a C&nbsp;function is created,
+it is possible to associate some values with it,
+thus creating a <em>C&nbsp;closure</em>;
+these values are called <em>upvalues</em> and are
+accessible to the function whenever it is called
+(see <a href="#lua_pushcclosure"><code>lua_pushcclosure</code></a>).
+
+
+<p>
+Whenever a C&nbsp;function is called,
+its upvalues are located at specific pseudo-indices.
+These pseudo-indices are produced by the macro
+<a name="lua_upvalueindex"><code>lua_upvalueindex</code></a>.
+The first value associated with a function is at position
+<code>lua_upvalueindex(1)</code>, and so on.
+Any access to <code>lua_upvalueindex(<em>n</em>)</code>,
+where <em>n</em> is greater than the number of upvalues of the
+current function (but not greater than 256),
+produces an acceptable (but invalid) index.
+
+
+
+
+
+<h2>3.5 - <a name="3.5">Registry</a></h2>
+
+<p>
+Lua provides a <em>registry</em>,
+a pre-defined table that can be used by any C&nbsp;code to
+store whatever Lua value it needs to store.
+This table is always located at pseudo-index
+<a name="pdf-LUA_REGISTRYINDEX"><code>LUA_REGISTRYINDEX</code></a>.
+Any C&nbsp;library can store data into this table,
+but it should take care to choose keys different from those used
+by other libraries, to avoid collisions.
+Typically, you should use as key a string containing your library name
+or a light userdata with the address of a C&nbsp;object in your code.
+
+
+<p>
+The integer keys in the registry are used by the reference mechanism,
+implemented by the auxiliary library,
+and therefore should not be used for other purposes.
+
+
+
+
+
+<h2>3.6 - <a name="3.6">Error Handling in C</a></h2>
+
+<p>
+Internally, Lua uses the C <code>longjmp</code> facility to handle errors.
+(You can also choose to use exceptions if you use C++;
+see file <code>luaconf.h</code>.)
+When Lua faces any error
+(such as memory allocation errors, type errors, syntax errors,
+and runtime errors)
+it <em>raises</em> an error;
+that is, it does a long jump.
+A <em>protected environment</em> uses <code>setjmp</code>
+to set a recover point;
+any error jumps to the most recent active recover point.
+
+
+<p>
+Most functions in the API can throw an error,
+for instance due to a memory allocation error.
+The documentation for each function indicates whether
+it can throw errors.
+
+
+<p>
+Inside a C&nbsp;function you can throw an error by calling <a href="#lua_error"><code>lua_error</code></a>.
+
+
+
+
+
+<h2>3.7 - <a name="3.7">Functions and Types</a></h2>
+
+<p>
+Here we list all functions and types from the C&nbsp;API in
+alphabetical order.
+Each function has an indicator like this:
+<span class="apii">[-o, +p, <em>x</em>]</span>
+
+
+<p>
+The first field, <code>o</code>,
+is how many elements the function pops from the stack.
+The second field, <code>p</code>,
+is how many elements the function pushes onto the stack.
+(Any function always pushes its results after popping its arguments.)
+A field in the form <code>x|y</code> means the function can push (or pop)
+<code>x</code> or <code>y</code> elements,
+depending on the situation;
+an interrogation mark '<code>?</code>' means that
+we cannot know how many elements the function pops/pushes
+by looking only at its arguments
+(e.g., they may depend on what is on the stack).
+The third field, <code>x</code>,
+tells whether the function may throw errors:
+'<code>-</code>' means the function never throws any error;
+'<code>m</code>' means the function may throw an error
+only due to not enough memory;
+'<code>e</code>' means the function may throw other kinds of errors;
+'<code>v</code>' means the function may throw an error on purpose.
+
+
+
+<hr><h3><a name="lua_Alloc"><code>lua_Alloc</code></a></h3>
+<pre>typedef void * (*lua_Alloc) (void *ud,
+                             void *ptr,
+                             size_t osize,
+                             size_t nsize);</pre>
+
+<p>
+The type of the memory-allocation function used by Lua states.
+The allocator function must provide a
+functionality similar to <code>realloc</code>,
+but not exactly the same.
+Its arguments are
+<code>ud</code>, an opaque pointer passed to <a href="#lua_newstate"><code>lua_newstate</code></a>;
+<code>ptr</code>, a pointer to the block being allocated/reallocated/freed;
+<code>osize</code>, the original size of the block;
+<code>nsize</code>, the new size of the block.
+<code>ptr</code> is <code>NULL</code> if and only if <code>osize</code> is zero.
+When <code>nsize</code> is zero, the allocator must return <code>NULL</code>;
+if <code>osize</code> is not zero,
+it should free the block pointed to by <code>ptr</code>.
+When <code>nsize</code> is not zero, the allocator returns <code>NULL</code>
+if and only if it cannot fill the request.
+When <code>nsize</code> is not zero and <code>osize</code> is zero,
+the allocator should behave like <code>malloc</code>.
+When <code>nsize</code> and <code>osize</code> are not zero,
+the allocator behaves like <code>realloc</code>.
+Lua assumes that the allocator never fails when
+<code>osize &gt;= nsize</code>.
+
+
+<p>
+Here is a simple implementation for the allocator function.
+It is used in the auxiliary library by <a href="#luaL_newstate"><code>luaL_newstate</code></a>.
+
+<pre>
+     static void *l_alloc (void *ud, void *ptr, size_t osize,

+       (void)ud;  (void)osize;  /* not used */

+Sets a new panic function and returns the old one.
+
+

+If an error happens outside any protected environment,
+Lua calls a <em>panic function</em>
+and then calls <code>exit(EXIT_FAILURE)</code>,
+thus exiting the host application.
+Your panic function can avoid this exit by
+never returning (e.g., doing a long jump).

+<pre>void lua_call (lua_State *L, int nargs, int nresults);</pre>
+
+<p>
+Calls a function.
+
+
+<p>
+To call a function you must use the following protocol:
+first, the function to be called is pushed onto the stack;
+then, the arguments to the function are pushed
+in direct order;
+that is, the first argument is pushed first.
+Finally you call <a href="#lua_call"><code>lua_call</code></a>;
+<code>nargs</code> is the number of arguments that you pushed onto the stack.
+All arguments and the function value are popped from the stack
+when the function is called.
+The function results are pushed onto the stack when the function returns.
+The number of results is adjusted to <code>nresults</code>,
+unless <code>nresults</code> is <a name="pdf-LUA_MULTRET"><code>LUA_MULTRET</code></a>.
+In this case, <em>all</em> results from the function are pushed.
+Lua takes care that the returned values fit into the stack space.
+The function results are pushed onto the stack in direct order
+(the first result is pushed first),
+so that after the call the last result is on the top of the stack.
+
+
+<p>
+Any error inside the called function is propagated upwards
+(with a <code>longjmp</code>).
+
+
+<p>
+The following example shows how the host program can do the
+equivalent to this Lua code:
+
+<pre>
+     a = f("how", t.x, 14)
+</pre><p>
+Here it is in&nbsp;C:
+
+<pre>
+     lua_getfield(L, LUA_GLOBALSINDEX, "f"); /* function to be called */
+     lua_pushstring(L, "how");                        /* 1st argument */
+     lua_getfield(L, LUA_GLOBALSINDEX, "t");   /* table to be indexed */
+     lua_getfield(L, -1, "x");        /* push result of t.x (2nd arg) */
+     lua_remove(L, -2);                  /* remove 't' from the stack */
+     lua_pushinteger(L, 14);                          /* 3rd argument */
+     lua_call(L, 3, 1);     /* call 'f' with 3 arguments and 1 result */
+     lua_setfield(L, LUA_GLOBALSINDEX, "a");        /* set global 'a' */
+</pre><p>
+Note that the code above is "balanced":
+at its end, the stack is back to its original configuration.
+This is considered good programming practice.

+
+<p>
+Type for C&nbsp;functions.
+
+
+<p>
+In order to communicate properly with Lua,
+a C&nbsp;function must use the following protocol,
+which defines the way parameters and results are passed:
+a C&nbsp;function receives its arguments from Lua in its stack
+in direct order (the first argument is pushed first).
+So, when the function starts,
+<code>lua_gettop(L)</code> returns the number of arguments received by the function.
+The first argument (if any) is at index 1
+and its last argument is at index <code>lua_gettop(L)</code>.
+To return values to Lua, a C&nbsp;function just pushes them onto the stack,
+in direct order (the first result is pushed first),
+and returns the number of results.
+Any other value in the stack below the results will be properly
+discarded by Lua.
+Like a Lua function, a C&nbsp;function called by Lua can also return
+many results.
+
+
+<p>
+As an example, the following function receives a variable number
+of numerical arguments and returns their average and sum:
+
+<pre>
+     static int foo (lua_State *L) {
+       int n = lua_gettop(L);    /* number of arguments */

+         if (!lua_isnumber(L, i)) {
+           lua_pushstring(L, "incorrect argument");
+           lua_error(L);
+         }
+         sum += lua_tonumber(L, i);
+       }
+       lua_pushnumber(L, sum/n);        /* first result */
+       lua_pushnumber(L, sum);         /* second result */

+and returns this address.
+
+
+<p>
+Userdata represent C&nbsp;values in Lua.

+A full userdata is only equal to itself (under raw equality).
+
+
+<p>
+When Lua collects a full userdata with a <code>gc</code> metamethod,
+Lua calls the metamethod and marks the userdata as finalized.
+When this userdata is collected again then
+Lua frees its corresponding memory.

+If there are no more elements in the table,
+then <a href="#lua_next"><code>lua_next</code></a> returns 0 (and pushes nothing).

+     while (lua_next(L, t) != 0) {

+
+<p>
+While traversing a table,
+do not call <a href="#lua_tolstring"><code>lua_tolstring</code></a> directly on a key,

+If there are no errors during the call,
+<a href="#lua_pcall"><code>lua_pcall</code></a> behaves exactly like <a href="#lua_call"><code>lua_call</code></a>.
+However, if there is any error,
+<a href="#lua_pcall"><code>lua_pcall</code></a> catches it,

+and returns an error code.
+Like <a href="#lua_call"><code>lua_call</code></a>,
+<a href="#lua_pcall"><code>lua_pcall</code></a> always removes the function
+and its arguments from the stack.
+
+
+<p>
+If <code>errfunc</code> is 0,
+then the error message returned on the stack
+is exactly the original error message.
+Otherwise, <code>errfunc</code> is the stack index of an
+<em>error handler function</em>.
+(In the current implementation, this index cannot be a pseudo-index.)
+In case of runtime errors,
+this function will be called with the error message
+and its return value will be the message returned on the stack by <a href="#lua_pcall"><code>lua_pcall</code></a>.
+
+
+<p>
+Typically, the error handler function is used to add more debug
+information to the error message, such as a stack traceback.
+Such information cannot be gathered after the return of <a href="#lua_pcall"><code>lua_pcall</code></a>,
+since by then the stack has unwound.

+<a name="pdf-LUA_HOOKTAILRET"><code>LUA_HOOKTAILRET</code></a>, <a name="pdf-LUA_HOOKLINE"><code>LUA_HOOKLINE</code></a>,
+and <a name="pdf-LUA_HOOKCOUNT"><code>LUA_HOOKCOUNT</code></a>.
+Moreover, for line events, the field <code>currentline</code> is also set.
+To get the value of any other field in <code>ar</code>,
+the hook must call <a href="#lua_getinfo"><code>lua_getinfo</code></a>.
+For return events, <code>event</code> can be <code>LUA_HOOKRET</code>,
+the normal value, or <code>LUA_HOOKTAILRET</code>.
+In the latter case, Lua is simulating a return from
+a function that did a tail call;
+in this case, it is useless to call <a href="#lua_getinfo"><code>lua_getinfo</code></a>.
+
+
+<p>
+While Lua is running a hook, it disables other calls to hooks.
+Therefore, if a hook calls back Lua to execute a function or a chunk,
+this execution occurs without any calls to hooks.

+
+<p>
+Sets the debugging hook function.
+
+
+<p>
+Argument <code>f</code> is the hook function.
+<code>mask</code> specifies on which events the hook will be called:
+it is formed by a bitwise or of the constants
+<a name="pdf-LUA_MASKCALL"><code>LUA_MASKCALL</code></a>,
+<a name="pdf-LUA_MASKRET"><code>LUA_MASKRET</code></a>,
+<a name="pdf-LUA_MASKLINE"><code>LUA_MASKLINE</code></a>,
+and <a name="pdf-LUA_MASKCOUNT"><code>LUA_MASKCOUNT</code></a>.
+The <code>count</code> argument is only meaningful when the mask
+includes <code>LUA_MASKCOUNT</code>.
+For each event, the hook is called as explained below:
+
+<ul>
+
+<li><b>The call hook:</b> is called when the interpreter calls a function.
+The hook is called just after Lua enters the new function,
+before the function gets its arguments.
+</li>
+
+<li><b>The return hook:</b> is called when the interpreter returns from a function.
+The hook is called just before Lua leaves the function.
+You have no access to the values to be returned by the function.
+</li>
+
+<li><b>The line hook:</b> is called when the interpreter is about to
+start the execution of a new line of code,
+or when it jumps back in the code (even to the same line).
+(This event only happens while Lua is executing a Lua function.)
+</li>
+
+<li><b>The count hook:</b> is called after the interpreter executes every
+<code>count</code> instructions.
+(This event only happens while Lua is executing a Lua function.)
+</li>
+
+</ul>
+
+<p>
+A hook is disabled by setting <code>mask</code> to zero.

+<h1>4 - <a name="4">The Auxiliary Library</a></h1>
+
+<p>
+
+The <em>auxiliary library</em> provides several convenient functions
+to interface C with Lua.
+While the basic API provides the primitive functions for all 
+interactions between C and Lua,
+the auxiliary library provides higher-level functions for some
+common tasks.
+
+
+<p>
+All functions from the auxiliary library
+are defined in header file <code>lauxlib.h</code> and
+have a prefix <code>luaL_</code>.
+
+
+<p>
+All functions in the auxiliary library are built on
+top of the basic API,
+and so they provide nothing that cannot be done with this API.
+
+
+<p>
+Several functions in the auxiliary library are used to
+check C&nbsp;function arguments.
+Their names are always <code>luaL_check*</code> or <code>luaL_opt*</code>.
+All of these functions throw an error if the check is not satisfied.
+Because the error message is formatted for arguments
+(e.g., "<code>bad argument #1</code>"),
+you should not use these functions for other stack values.
+
+
+
+<h2>4.1 - <a name="4.1">Functions and Types</a></h2>

+<p>
+Here we list all functions and types from the auxiliary library
+in alphabetical order.

+<hr><h3><a name="luaL_Buffer"><code>luaL_Buffer</code></a></h3>
+<pre>typedef struct luaL_Buffer luaL_Buffer;</pre>
+
+<p>
+Type for a <em>string buffer</em>.
+
+
+<p>
+A string buffer allows C&nbsp;code to build Lua strings piecemeal.
+Its pattern of use is as follows:
+
+<ul>
+
+<li>First you declare a variable <code>b</code> of type <a href="#luaL_Buffer"><code>luaL_Buffer</code></a>.</li>
+
+<li>Then you initialize it with a call <code>luaL_buffinit(L, &amp;b)</code>.</li>
+
+<li>
+Then you add string pieces to the buffer calling any of
+the <code>luaL_add*</code> functions.
+</li>
+
+<li>
+You finish by calling <code>luaL_pushresult(&amp;b)</code>.
+This call leaves the final string on the top of the stack.
+</li>
+
+</ul>
+
+<p>
+During its normal operation,
+a string buffer uses a variable number of stack slots.
+So, while using a buffer, you cannot assume that you know where
+the top of the stack is.
+You can use the stack between successive calls to buffer operations
+as long as that use is balanced;
+that is,
+when you call a buffer operation,
+the stack is at the same level
+it was immediately after the previous buffer operation.
+(The only exception to this rule is <a href="#luaL_addvalue"><code>luaL_addvalue</code></a>.)
+After calling <a href="#luaL_pushresult"><code>luaL_pushresult</code></a> the stack is back to its
+level when the buffer was initialized,
+plus the final string on its top.

+<h1>5 - <a name="5">Standard Libraries</a></h1>
+
+<p>
+The standard Lua libraries provide useful functions
+that are implemented directly through the C&nbsp;API.
+Some of these functions provide essential services to the language
+(e.g., <a href="#pdf-type"><code>type</code></a> and <a href="#pdf-getmetatable"><code>getmetatable</code></a>);
+others provide access to "outside" services (e.g., I/O);
+and others could be implemented in Lua itself,
+but are quite useful or have critical performance requirements that
+deserve an implementation in C (e.g., <a href="#pdf-table.sort"><code>table.sort</code></a>).
+
+
+<p>
+All libraries are implemented through the official C&nbsp;API
+and are provided as separate C&nbsp;modules.
+Currently, Lua has the following standard libraries:
+
+<ul>
+
+<li>basic library, which includes the coroutine sub-library;</li>
+
+<li>package library;</li>
+
+<li>string manipulation;</li>
+
+<li>table manipulation;</li>
+
+<li>mathematical functions (sin, log, etc.);</li>
+
+<li>input and output;</li>
+
+<li>operating system facilities;</li>
+
+<li>debug facilities.</li>
+
+</ul><p>
+Except for the basic and package libraries,
+each library provides all its functions as fields of a global table
+or as methods of its objects.
+
+
+<p>
+To have access to these libraries,
+the C&nbsp;host program should call the <a href="#luaL_openlibs"><code>luaL_openlibs</code></a> function,
+which opens all standard libraries.
+Alternatively,
+it can open them individually by calling
+<a name="pdf-luaopen_base"><code>luaopen_base</code></a> (for the basic library),
+<a name="pdf-luaopen_package"><code>luaopen_package</code></a> (for the package library),
+<a name="pdf-luaopen_string"><code>luaopen_string</code></a> (for the string library),
+<a name="pdf-luaopen_table"><code>luaopen_table</code></a> (for the table library),
+<a name="pdf-luaopen_math"><code>luaopen_math</code></a> (for the mathematical library),
+<a name="pdf-luaopen_io"><code>luaopen_io</code></a> (for the I/O library),
+<a name="pdf-luaopen_os"><code>luaopen_os</code></a> (for the Operating System library),
+and <a name="pdf-luaopen_debug"><code>luaopen_debug</code></a> (for the debug library).
+These functions are declared in <a name="pdf-lualib.h"><code>lualib.h</code></a>
+and should not be called directly:
+you must call them like any other Lua C&nbsp;function,
+e.g., by using <a href="#lua_call"><code>lua_call</code></a>.
+
+
+
+<h2>5.1 - <a name="5.1">Basic Functions</a></h2>
+
+<p>
+The basic library provides some core functions to Lua.
+If you do not include this library in your application,
+you should check carefully whether you need to provide 
+implementations for some of its facilities.
+
+
+<p>
+<hr><h3><a name="pdf-assert"><code>assert (v [, message])</code></a></h3>
+Issues an  error when
+the value of its argument <code>v</code> is false (i.e., <b>nil</b> or <b>false</b>);
+otherwise, returns all its arguments.
+<code>message</code> is an error message;
+when absent, it defaults to "assertion failed!"
+
+
+
+
+<p>
+<hr><h3><a name="pdf-collectgarbage"><code>collectgarbage ([opt [, arg]])</code></a></h3>
+
+
+<p>
+This function is a generic interface to the garbage collector.
+It performs different functions according to its first argument, <code>opt</code>:
+
+<ul>
+
+<li><b>"collect":</b>
+performs a full garbage-collection cycle.
+This is the default option.
+</li>
+
+<li><b>"stop":</b>
+stops the garbage collector.
+</li>
+
+<li><b>"restart":</b>
+restarts the garbage collector.
+</li>
+
+<li><b>"count":</b>
+returns the total memory in use by Lua (in Kbytes).
+</li>
+
+<li><b>"step":</b>
+performs a garbage-collection step.
+The step "size" is controlled by <code>arg</code>
+(larger values mean more steps) in a non-specified way.
+If you want to control the step size
+you must experimentally tune the value of <code>arg</code>.
+Returns <b>true</b> if the step finished a collection cycle.
+</li>
+
+<li><b>"setpause":</b>
+sets <code>arg</code> as the new value for the <em>pause</em> of
+the collector (see <a href="#2.10">&sect;2.10</a>).
+Returns the previous value for <em>pause</em>.
+</li>
+
+<li><b>"setstepmul":</b>
+sets <code>arg</code> as the new value for the <em>step multiplier</em> of
+the collector (see <a href="#2.10">&sect;2.10</a>).
+Returns the previous value for <em>step</em>.
+</li>
+
+</ul>
+
+
+
+<p>
+<hr><h3><a name="pdf-dofile"><code>dofile ([filename])</code></a></h3>
+Opens the named file and executes its contents as a Lua chunk.
+When called without arguments,
+<code>dofile</code> executes the contents of the standard input (<code>stdin</code>).
+Returns all values returned by the chunk.
+In case of errors, <code>dofile</code> propagates the error
+to its caller (that is, <code>dofile</code> does not run in protected mode).
+
+
+
+
+<p>
+<hr><h3><a name="pdf-error"><code>error (message [, level])</code></a></h3>
+Terminates the last protected function called
+and returns <code>message</code> as the error message.
+Function <code>error</code> never returns.
+
+
+<p>
+Usually, <code>error</code> adds some information about the error position
+at the beginning of the message.
+The <code>level</code> argument specifies how to get the error position.
+With level&nbsp;1 (the default), the error position is where the
+<code>error</code> function was called.
+Level&nbsp;2 points the error to where the function
+that called <code>error</code> was called; and so on.
+Passing a level&nbsp;0 avoids the addition of error position information
+to the message.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-_G"><code>_G</code></a></h3>
+A global variable (not a function) that
+holds the global environment (that is, <code>_G._G = _G</code>).
+Lua itself does not use this variable;
+changing its value does not affect any environment,
+nor vice-versa.
+(Use <a href="#pdf-setfenv"><code>setfenv</code></a> to change environments.)
+
+
+
+
+<p>
+<hr><h3><a name="pdf-getfenv"><code>getfenv ([f])</code></a></h3>
+Returns the current environment in use by the function.
+<code>f</code> can be a Lua function or a number
+that specifies the function at that stack level:
+Level&nbsp;1 is the function calling <code>getfenv</code>.
+If the given function is not a Lua function,
+or if <code>f</code> is 0,
+<code>getfenv</code> returns the global environment.
+The default for <code>f</code> is 1.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-getmetatable"><code>getmetatable (object)</code></a></h3>
+
+
+<p>
+If <code>object</code> does not have a metatable, returns <b>nil</b>.
+Otherwise,
+if the object's metatable has a <code>"__metatable"</code> field,
+returns the associated value.
+Otherwise, returns the metatable of the given object.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-ipairs"><code>ipairs (t)</code></a></h3>
+
+
+<p>

+so that the construction
+
+<pre>
+     for i,v in ipairs(t) do <em>body</em> end
+</pre><p>

+up to the first integer key absent from the table.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-load"><code>load (func [, chunkname])</code></a></h3>
+
+
+<p>
+Loads a chunk using function <code>func</code> to get its pieces.
+Each call to <code>func</code> must return a string that concatenates
+with previous results.
+A return of an empty string, <b>nil</b>, or no value signals the end of the chunk.
+
+
+<p>
+If there are no errors, 
+returns the compiled chunk as a function;
+otherwise, returns <b>nil</b> plus the error message.
+The environment of the returned function is the global environment.
+
+
+<p>
+<code>chunkname</code> is used as the chunk name for error messages
+and debug information.
+When absent,
+it defaults to "<code>=(load)</code>".
+
+
+
+
+<p>
+<hr><h3><a name="pdf-loadfile"><code>loadfile ([filename])</code></a></h3>
+
+
+<p>
+Similar to <a href="#pdf-load"><code>load</code></a>,
+but gets the chunk from file <code>filename</code>
+or from the standard input,
+if no file name is given.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-loadstring"><code>loadstring (string [, chunkname])</code></a></h3>
+
+
+<p>
+Similar to <a href="#pdf-load"><code>load</code></a>,
+but gets the chunk from the given string.
+
+
+<p>
+To load and run a given string, use the idiom
+
+<pre>
+     assert(loadstring(s))()
+</pre>
+
+<p>
+When absent,
+<code>chunkname</code> defaults to the given string.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-next"><code>next (table [, index])</code></a></h3>
+
+
+<p>
+Allows a program to traverse all fields of a table.
+Its first argument is a table and its second argument
+is an index in this table.
+<code>next</code> returns the next index of the table
+and its associated value.
+When called with <b>nil</b> as its second argument,
+<code>next</code> returns an initial index
+and its associated value.
+When called with the last index,
+or with <b>nil</b> in an empty table,
+<code>next</code> returns <b>nil</b>.
+If the second argument is absent, then it is interpreted as <b>nil</b>.
+In particular,
+you can use <code>next(t)</code> to check whether a table is empty.
+
+
+<p>
+The order in which the indices are enumerated is not specified,
+<em>even for numeric indices</em>.
+(To traverse a table in numeric order,
+use a numerical <b>for</b> or the <a href="#pdf-ipairs"><code>ipairs</code></a> function.)
+
+
+<p>
+The behavior of <code>next</code> is <em>undefined</em> if,
+during the traversal,
+you assign any value to a non-existent field in the table.
+You may however modify existing fields.
+In particular, you may clear existing fields.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-pairs"><code>pairs (t)</code></a></h3>
+
+
+<p>
+Returns three values: the <a href="#pdf-next"><code>next</code></a> function, the table <code>t</code>, and <b>nil</b>,
+so that the construction
+
+<pre>
+     for k,v in pairs(t) do <em>body</em> end
+</pre><p>
+will iterate over all key&ndash;value pairs of table <code>t</code>.
+

+See function <a href="#pdf-next"><code>next</code></a> for the caveats of modifying
+the table during its traversal.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-pcall"><code>pcall (f, arg1, &middot;&middot;&middot;)</code></a></h3>
+
+
+<p>
+Calls function <code>f</code> with
+the given arguments in <em>protected mode</em>.
+This means that any error inside&nbsp;<code>f</code> is not propagated;
+instead, <code>pcall</code> catches the error
+and returns a status code.
+Its first result is the status code (a boolean),
+which is true if the call succeeds without errors.
+In such case, <code>pcall</code> also returns all results from the call,
+after this first result.
+In case of any error, <code>pcall</code> returns <b>false</b> plus the error message.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-print"><code>print (&middot;&middot;&middot;)</code></a></h3>

+
+<h2>5.3 - <a name="5.3">Modules</a></h2>
+
+<p>
+The package library provides basic
+facilities for loading and building modules in Lua.
+It exports two of its functions directly in the global environment:
+<a href="#pdf-require"><code>require</code></a> and <a href="#pdf-module"><code>module</code></a>.
+Everything else is exported in a table <a name="pdf-package"><code>package</code></a>.
+
+
+<p>
+<hr><h3><a name="pdf-module"><code>module (name [, &middot;&middot;&middot;])</code></a></h3>
+
+
+<p>
+Creates a module.
+If there is a table in <code>package.loaded[name]</code>,
+this table is the module.
+Otherwise, if there is a global table <code>t</code> with the given name,
+this table is the module.
+Otherwise creates a new table <code>t</code> and
+sets it as the value of the global <code>name</code> and
+the value of <code>package.loaded[name]</code>.
+This function also initializes <code>t._NAME</code> with the given name,
+<code>t._M</code> with the module (<code>t</code> itself),
+and <code>t._PACKAGE</code> with the package name
+(the full module name minus last component; see below).
+Finally, <code>module</code> sets <code>t</code> as the new environment
+of the current function and the new value of <code>package.loaded[name]</code>,
+so that <a href="#pdf-require"><code>require</code></a> returns <code>t</code>.
+
+
+<p>
+If <code>name</code> is a compound name
+(that is, one with components separated by dots),
+<code>module</code> creates (or reuses, if they already exist)
+tables for each component.
+For instance, if <code>name</code> is <code>a.b.c</code>,
+then <code>module</code> stores the module table in field <code>c</code> of
+field <code>b</code> of global <code>a</code>.
+
+
+<p>
+This function can receive optional <em>options</em> after
+the module name,
+where each option is a function to be applied over the module.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-require"><code>require (modname)</code></a></h3>
+
+
+<p>
+Loads the given module.
+The function starts by looking into the <a href="#pdf-package.loaded"><code>package.loaded</code></a> table
+to determine whether <code>modname</code> is already loaded.
+If it is, then <code>require</code> returns the value stored
+at <code>package.loaded[modname]</code>.
+Otherwise, it tries to find a <em>loader</em> for the module.
+
+
+<p>
+To find a loader,
+<code>require</code> is guided by the <a href="#pdf-package.loaders"><code>package.loaders</code></a> array.
+By changing this array,
+we can change how <code>require</code> looks for a module.
+The following explanation is based on the default configuration
+for <a href="#pdf-package.loaders"><code>package.loaders</code></a>.
+
+
+<p>
+First <code>require</code> queries <code>package.preload[modname]</code>.
+If it has a value,
+this value (which should be a function) is the loader.
+Otherwise <code>require</code> searches for a Lua loader using the
+path stored in <a href="#pdf-package.path"><code>package.path</code></a>.
+If that also fails, it searches for a C&nbsp;loader using the
+path stored in <a href="#pdf-package.cpath"><code>package.cpath</code></a>.
+If that also fails,
+it tries an <em>all-in-one</em> loader (see <a href="#pdf-package.loaders"><code>package.loaders</code></a>).
+
+
+<p>
+Once a loader is found,
+<code>require</code> calls the loader with a single argument, <code>modname</code>.
+If the loader returns any value,
+<code>require</code> assigns the returned value to <code>package.loaded[modname]</code>.
+If the loader returns no value and
+has not assigned any value to <code>package.loaded[modname]</code>,
+then <code>require</code> assigns <b>true</b> to this entry.
+In any case, <code>require</code> returns the
+final value of <code>package.loaded[modname]</code>.
+
+
+<p>
+If there is any error loading or running the module,
+or if it cannot find any loader for the module,
+then <code>require</code> signals an error. 
+
+
+
+
+<p>
+<hr><h3><a name="pdf-package.cpath"><code>package.cpath</code></a></h3>
+
+
+<p>
+The path used by <a href="#pdf-require"><code>require</code></a> to search for a C&nbsp;loader.
+
+
+<p>
+Lua initializes the C&nbsp;path <a href="#pdf-package.cpath"><code>package.cpath</code></a> in the same way
+it initializes the Lua path <a href="#pdf-package.path"><code>package.path</code></a>,
+using the environment variable <a name="pdf-LUA_CPATH"><code>LUA_CPATH</code></a>
+or a default path defined in <code>luaconf.h</code>.
+
+
+
+
+<p>
+
+<hr><h3><a name="pdf-package.loaded"><code>package.loaded</code></a></h3>
+
+
+<p>
+A table used by <a href="#pdf-require"><code>require</code></a> to control which
+modules are already loaded.
+When you require a module <code>modname</code> and
+<code>package.loaded[modname]</code> is not false,
+<a href="#pdf-require"><code>require</code></a> simply returns the value stored there.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-package.loaders"><code>package.loaders</code></a></h3>
+
+
+<p>
+A table used by <a href="#pdf-require"><code>require</code></a> to control how to load modules.
+
+
+<p>
+Each entry in this table is a <em>searcher function</em>.
+When looking for a module,
+<a href="#pdf-require"><code>require</code></a> calls each of these searchers in ascending order,
+with the module name (the argument given to <a href="#pdf-require"><code>require</code></a>) as its
+sole parameter.
+The function can return another function (the module <em>loader</em>)
+or a string explaining why it did not find that module
+(or <b>nil</b> if it has nothing to say).
+Lua initializes this table with four functions.
+
+
+<p>
+The first searcher simply looks for a loader in the
+<a href="#pdf-package.preload"><code>package.preload</code></a> table.
+
+
+<p>
+The second searcher looks for a loader as a Lua library,
+using the path stored at <a href="#pdf-package.path"><code>package.path</code></a>.
+A path is a sequence of <em>templates</em> separated by semicolons.
+For each template,
+the searcher will change each interrogation
+mark in the template by <code>filename</code>,
+which is the module name with each dot replaced by a
+"directory separator" (such as "<code>/</code>" in Unix);
+then it will try to open the resulting file name.
+So, for instance, if the Lua path is the string
+
+<pre>
+     "./?.lua;./?.lc;/usr/local/?/init.lua"
+</pre><p>
+the search for a Lua file for module <code>foo</code>
+will try to open the files
+<code>./foo.lua</code>, <code>./foo.lc</code>, and
+<code>/usr/local/foo/init.lua</code>, in that order.
+
+
+<p>
+The third searcher looks for a loader as a C&nbsp;library,
+using the path given by the variable <a href="#pdf-package.cpath"><code>package.cpath</code></a>.
+For instance,
+if the C&nbsp;path is the string
+
+<pre>
+     "./?.so;./?.dll;/usr/local/?/init.so"
+</pre><p>
+the searcher for module <code>foo</code>
+will try to open the files <code>./foo.so</code>, <code>./foo.dll</code>,
+and <code>/usr/local/foo/init.so</code>, in that order.
+Once it finds a C&nbsp;library,
+this searcher first uses a dynamic link facility to link the
+application with the library.
+Then it tries to find a C&nbsp;function inside the library to
+be used as the loader.
+The name of this C&nbsp;function is the string "<code>luaopen_</code>"
+concatenated with a copy of the module name where each dot
+is replaced by an underscore.
+Moreover, if the module name has a hyphen,
+its prefix up to (and including) the first hyphen is removed.
+For instance, if the module name is <code>a.v1-b.c</code>,
+the function name will be <code>luaopen_b_c</code>.
+
+
+<p>
+The fourth searcher tries an <em>all-in-one loader</em>.
+It searches the C&nbsp;path for a library for
+the root name of the given module.
+For instance, when requiring <code>a.b.c</code>,
+it will search for a C&nbsp;library for <code>a</code>.
+If found, it looks into it for an open function for
+the submodule;
+in our example, that would be <code>luaopen_a_b_c</code>.
+With this facility, a package can pack several C&nbsp;submodules
+into one single library,
+with each submodule keeping its original open function.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-package.loadlib"><code>package.loadlib (libname, funcname)</code></a></h3>
+
+
+<p>
+Dynamically links the host program with the C&nbsp;library <code>libname</code>.
+Inside this library, looks for a function <code>funcname</code>
+and returns this function as a C&nbsp;function.
+(So, <code>funcname</code> must follow the protocol (see <a href="#lua_CFunction"><code>lua_CFunction</code></a>)).
+
+
+<p>
+This is a low-level function.
+It completely bypasses the package and module system.
+Unlike <a href="#pdf-require"><code>require</code></a>,
+it does not perform any path searching and
+does not automatically adds extensions.
+<code>libname</code> must be the complete file name of the C&nbsp;library,
+including if necessary a path and extension.
+<code>funcname</code> must be the exact name exported by the C&nbsp;library
+(which may depend on the C&nbsp;compiler and linker used).
+
+
+<p>
+This function is not supported by ANSI C.
+As such, it is only available on some platforms
+(Windows, Linux, Mac OS X, Solaris, BSD,
+plus other Unix systems that support the <code>dlfcn</code> standard).
+

+
+
+<p>
+The path used by <a href="#pdf-require"><code>require</code></a> to search for a Lua loader.
+
+
+<p>
+At start-up, Lua initializes this variable with
+the value of the environment variable <a name="pdf-LUA_PATH"><code>LUA_PATH</code></a> or
+with a default path defined in <code>luaconf.h</code>,
+if the environment variable is not defined.
+Any "<code>;;</code>" in the value of the environment variable
+is replaced by the default path.
+
+
+
+

+<p>
+<hr><h3><a name="pdf-package.seeall"><code>package.seeall (module)</code></a></h3>
+
+

+
+<h2>5.4 - <a name="5.4">String Manipulation</a></h2>
+
+<p>
+This library provides generic functions for string manipulation,
+such as finding and extracting substrings, and pattern matching.
+When indexing a string in Lua, the first character is at position&nbsp;1
+(not at&nbsp;0, as in C).
+Indices are allowed to be negative and are interpreted as indexing backwards,
+from the end of the string.
+Thus, the last character is at position -1, and so on.
+
+
+<p>
+The string library provides all its functions inside the table
+<a name="pdf-string"><code>string</code></a>.
+It also sets a metatable for strings
+where the <code>__index</code> field points to the <code>string</code> table.
+Therefore, you can use the string functions in object-oriented style.
+For instance, <code>string.byte(s, i)</code>
+can be written as <code>s:byte(i)</code>.
+
+
+<p>
+The string library assumes one-byte character encodings.
+
+
+<p>
+<hr><h3><a name="pdf-string.byte"><code>string.byte (s [, i [, j]])</code></a></h3>
+Returns the internal numerical codes of the characters <code>s[i]</code>,
+<code>s[i+1]</code>, &middot;&middot;&middot;, <code>s[j]</code>.
+The default value for <code>i</code> is&nbsp;1;
+the default value for <code>j</code> is&nbsp;<code>i</code>.
+
+
+<p>
+Note that numerical codes are not necessarily portable across platforms.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-string.char"><code>string.char (&middot;&middot;&middot;)</code></a></h3>
+Receives zero or more integers.
+Returns a string with length equal to the number of arguments,
+in which each character has the internal numerical code equal
+to its corresponding argument.
+
+
+<p>
+Note that numerical codes are not necessarily portable across platforms.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-string.dump"><code>string.dump (function)</code></a></h3>
+
+
+<p>
+Returns a string containing a binary representation of the given function,
+so that a later <a href="#pdf-loadstring"><code>loadstring</code></a> on this string returns
+a copy of the function.
+<code>function</code> must be a Lua function without upvalues.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-string.find"><code>string.find (s, pattern [, init [, plain]])</code></a></h3>
+Looks for the first match of
+<code>pattern</code> in the string <code>s</code>.
+If it finds a match, then <code>find</code> returns the indices of&nbsp;<code>s</code>
+where this occurrence starts and ends;
+otherwise, it returns <b>nil</b>.
+A third, optional numerical argument <code>init</code> specifies
+where to start the search;
+its default value is&nbsp;1 and can be negative.
+A value of <b>true</b> as a fourth, optional argument <code>plain</code>
+turns off the pattern matching facilities,
+so the function does a plain "find substring" operation,
+with no characters in <code>pattern</code> being considered "magic".
+Note that if <code>plain</code> is given, then <code>init</code> must be given as well.
+
+
+<p>
+If the pattern has captures,
+then in a successful match
+the captured values are also returned,
+after the two indices.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-string.format"><code>string.format (formatstring, &middot;&middot;&middot;)</code></a></h3>
+Returns a formatted version of its variable number of arguments
+following the description given in its first argument (which must be a string).
+The format string follows the same rules as the <code>printf</code> family of
+standard C&nbsp;functions.
+The only differences are that the options/modifiers
+<code>*</code>, <code>l</code>, <code>L</code>, <code>n</code>, <code>p</code>,
+and <code>h</code> are not supported
+and that there is an extra option, <code>q</code>.
+The <code>q</code> option formats a string in a form suitable to be safely read
+back by the Lua interpreter:
+the string is written between double quotes,
+and all double quotes, newlines, embedded zeros,
+and backslashes in the string
+are correctly escaped when written.
+For instance, the call
+
+<pre>
+     string.format('%q', 'a string with "quotes" and \n new line')
+</pre><p>
+will produce the string:
+
+<pre>
+     "a string with \"quotes\" and \
+      new line"
+</pre>
+
+<p>
+The options <code>c</code>, <code>d</code>, <code>E</code>, <code>e</code>, <code>f</code>,
+<code>g</code>, <code>G</code>, <code>i</code>, <code>o</code>, <code>u</code>, <code>X</code>, and <code>x</code> all
+expect a number as argument,
+whereas <code>q</code> and <code>s</code> expect a string.
+
+
+<p>
+This function does not accept string values
+containing embedded zeros,
+except as arguments to the <code>q</code> option.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-string.gmatch"><code>string.gmatch (s, pattern)</code></a></h3>
+Returns an iterator function that,
+each time it is called,
+returns the next captures from <code>pattern</code> over string <code>s</code>.
+If <code>pattern</code> specifies no captures,
+then the whole match is produced in each call.
+
+
+<p>
+As an example, the following loop
+
+<pre>
+     s = "hello world from Lua"
+     for w in string.gmatch(s, "%a+") do
+       print(w)
+     end
+</pre><p>
+will iterate over all the words from string <code>s</code>,
+printing one per line.
+The next example collects all pairs <code>key=value</code> from the
+given string into a table:
+
+<pre>
+     t = {}
+     s = "from=world, to=Lua"
+     for k, v in string.gmatch(s, "(%w+)=(%w+)") do
+       t[k] = v
+     end
+</pre>
+
+<p>
+For this function, a '<code>^</code>' at the start of a pattern does not
+work as an anchor, as this would prevent the iteration.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-string.gsub"><code>string.gsub (s, pattern, repl [, n])</code></a></h3>
+Returns a copy of <code>s</code>
+in which all (or the first <code>n</code>, if given)
+occurrences of the <code>pattern</code> have been
+replaced by a replacement string specified by <code>repl</code>,
+which can be a string, a table, or a function.
+<code>gsub</code> also returns, as its second value,
+the total number of matches that occurred.
+
+
+<p>
+If <code>repl</code> is a string, then its value is used for replacement.
+The character&nbsp;<code>%</code> works as an escape character:
+any sequence in <code>repl</code> of the form <code>%<em>n</em></code>,
+with <em>n</em> between 1 and 9,
+stands for the value of the <em>n</em>-th captured substring (see below).
+The sequence <code>%0</code> stands for the whole match.
+The sequence <code>%%</code> stands for a single&nbsp;<code>%</code>.
+
+
+<p>
+If <code>repl</code> is a table, then the table is queried for every match,
+using the first capture as the key;
+if the pattern specifies no captures,
+then the whole match is used as the key.
+
+
+<p>
+If <code>repl</code> is a function, then this function is called every time a
+match occurs, with all captured substrings passed as arguments,
+in order;
+if the pattern specifies no captures,
+then the whole match is passed as a sole argument.
+
+
+<p>
+If the value returned by the table query or by the function call
+is a string or a number,
+then it is used as the replacement string;
+otherwise, if it is <b>false</b> or <b>nil</b>,
+then there is no replacement
+(that is, the original match is kept in the string).
+
+
+<p>
+Here are some examples:
+
+<pre>
+     x = string.gsub("hello world", "(%w+)", "%1 %1")
+     --&gt; x="hello hello world world"
+     
+     x = string.gsub("hello world", "%w+", "%0 %0", 1)
+     --&gt; x="hello hello world"
+     
+     x = string.gsub("hello world from Lua", "(%w+)%s*(%w+)", "%2 %1")
+     --&gt; x="world hello Lua from"
+     
+     x = string.gsub("home = $HOME, user = $USER", "%$(%w+)", os.getenv)
+     --&gt; x="home = /home/roberto, user = roberto"
+     
+     x = string.gsub("4+5 = $return 4+5$", "%$(.-)%$", function (s)
+           return loadstring(s)()
+         end)
+     --&gt; x="4+5 = 9"
+     
+     local t = {name="lua", version="5.1"}
+     x = string.gsub("$name-$version.tar.gz", "%$(%w+)", t)

+<h3>5.4.1 - <a name="5.4.1">Patterns</a></h3>
+
+
+<h4>Character Class:</h4><p>
+A <em>character class</em> is used to represent a set of characters.
+The following combinations are allowed in describing a character class:
+
+<ul>
+
+<li><b><em>x</em>:</b>
+(where <em>x</em> is not one of the <em>magic characters</em>
+<code>^$()%.[]*+-?</code>)
+represents the character <em>x</em> itself.
+</li>
+
+<li><b><code>.</code>:</b> (a dot) represents all characters.</li>
+
+<li><b><code>%a</code>:</b> represents all letters.</li>
+
+<li><b><code>%c</code>:</b> represents all control characters.</li>
+
+<li><b><code>%d</code>:</b> represents all digits.</li>
+
+<li><b><code>%l</code>:</b> represents all lowercase letters.</li>
+
+<li><b><code>%p</code>:</b> represents all punctuation characters.</li>
+
+<li><b><code>%s</code>:</b> represents all space characters.</li>
+
+<li><b><code>%u</code>:</b> represents all uppercase letters.</li>
+
+<li><b><code>%w</code>:</b> represents all alphanumeric characters.</li>
+
+<li><b><code>%x</code>:</b> represents all hexadecimal digits.</li>
+
+<li><b><code>%z</code>:</b> represents the character with representation 0.</li>
+
+<li><b><code>%<em>x</em></code>:</b> (where <em>x</em> is any non-alphanumeric character)
+represents the character <em>x</em>.
+This is the standard way to escape the magic characters.
+Any punctuation character (even the non magic)
+can be preceded by a '<code>%</code>'
+when used to represent itself in a pattern.
+</li>
+
+<li><b><code>[<em>set</em>]</code>:</b>
+represents the class which is the union of all
+characters in <em>set</em>.
+A range of characters can be specified by
+separating the end characters of the range with a '<code>-</code>'.
+All classes <code>%</code><em>x</em> described above can also be used as
+components in <em>set</em>.
+All other characters in <em>set</em> represent themselves.
+For example, <code>[%w_]</code> (or <code>[_%w]</code>)
+represents all alphanumeric characters plus the underscore,
+<code>[0-7]</code> represents the octal digits,
+and <code>[0-7%l%-]</code> represents the octal digits plus
+the lowercase letters plus the '<code>-</code>' character.
+
+
+<p>
+The interaction between ranges and classes is not defined.
+Therefore, patterns like <code>[%a-z]</code> or <code>[a-%%]</code>
+have no meaning.
+</li>
+
+<li><b><code>[^<em>set</em>]</code>:</b>
+represents the complement of <em>set</em>,
+where <em>set</em> is interpreted as above.
+</li>
+
+</ul><p>
+For all classes represented by single letters (<code>%a</code>, <code>%c</code>, etc.),
+the corresponding uppercase letter represents the complement of the class.
+For instance, <code>%S</code> represents all non-space characters.
+
+
+<p>
+The definitions of letter, space, and other character groups
+depend on the current locale.
+In particular, the class <code>[a-z]</code> may not be equivalent to <code>%l</code>.
+
+
+
+
+
+<h4>Pattern Item:</h4><p>
+A <em>pattern item</em> can be
+
+<ul>
+
+<li>
+a single character class,
+which matches any single character in the class;
+</li>
+
+<li>
+a single character class followed by '<code>*</code>',
+which matches 0 or more repetitions of characters in the class.
+These repetition items will always match the longest possible sequence;
+</li>
+
+<li>
+a single character class followed by '<code>+</code>',
+which matches 1 or more repetitions of characters in the class.
+These repetition items will always match the longest possible sequence;
+</li>
+
+<li>
+a single character class followed by '<code>-</code>',
+which also matches 0 or more repetitions of characters in the class.
+Unlike '<code>*</code>',
+these repetition items will always match the <em>shortest</em> possible sequence;
+</li>
+
+<li>
+a single character class followed by '<code>?</code>',
+which matches 0 or 1 occurrence of a character in the class;
+</li>
+
+<li>
+<code>%<em>n</em></code>, for <em>n</em> between 1 and 9;
+such item matches a substring equal to the <em>n</em>-th captured string
+(see below);
+</li>
+
+<li>
+<code>%b<em>xy</em></code>, where <em>x</em> and <em>y</em> are two distinct characters;
+such item matches strings that start with&nbsp;<em>x</em>, end with&nbsp;<em>y</em>,
+and where the <em>x</em> and <em>y</em> are <em>balanced</em>.
+This means that, if one reads the string from left to right,
+counting <em>+1</em> for an <em>x</em> and <em>-1</em> for a <em>y</em>,
+the ending <em>y</em> is the first <em>y</em> where the count reaches 0.
+For instance, the item <code>%b()</code> matches expressions with
+balanced parentheses.
+</li>
+
+</ul>
+
+
+
+
+<h4>Pattern:</h4><p>
+A <em>pattern</em> is a sequence of pattern items.
+A '<code>^</code>' at the beginning of a pattern anchors the match at the
+beginning of the subject string.
+A '<code>$</code>' at the end of a pattern anchors the match at the
+end of the subject string.
+At other positions,
+'<code>^</code>' and '<code>$</code>' have no special meaning and represent themselves.
+
+
+
+
+
+<h4>Captures:</h4><p>
+A pattern can contain sub-patterns enclosed in parentheses;
+they describe <em>captures</em>.
+When a match succeeds, the substrings of the subject string
+that match captures are stored (<em>captured</em>) for future use.
+Captures are numbered according to their left parentheses.
+For instance, in the pattern <code>"(a*(.)%w(%s*))"</code>,
+the part of the string matching <code>"a*(.)%w(%s*)"</code> is
+stored as the first capture (and therefore has number&nbsp;1);
+the character matching "<code>.</code>" is captured with number&nbsp;2,
+and the part matching "<code>%s*</code>" has number&nbsp;3.
+
+
+<p>
+As a special case, the empty capture <code>()</code> captures
+the current string position (a number).
+For instance, if we apply the pattern <code>"()aa()"</code> on the
+string <code>"flaaap"</code>, there will be two captures: 3&nbsp;and&nbsp;5.
+
+
+<p>
+A pattern cannot contain embedded zeros.  Use <code>%z</code> instead.

+<h2>5.5 - <a name="5.5">Table Manipulation</a></h2><p>
+This library provides generic functions for table manipulation.
+It provides all its functions inside the table <a name="pdf-table"><code>table</code></a>.
+
+
+<p>
+Most functions in the table library assume that the table
+represents an array or a list.
+For these functions, when we talk about the "length" of a table
+we mean the result of the length operator.
+
+
+<p>
+<hr><h3><a name="pdf-table.concat"><code>table.concat (table [, sep [, i [, j]]])</code></a></h3>
+Given an array where all elements are strings or numbers,
+returns <code>table[i]..sep..table[i+1] &middot;&middot;&middot; sep..table[j]</code>.
+The default value for <code>sep</code> is the empty string,
+the default for <code>i</code> is 1,
+and the default for <code>j</code> is the length of the table.
+If <code>i</code> is greater than <code>j</code>, returns the empty string.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-table.insert"><code>table.insert (table, [pos,] value)</code></a></h3>
+
+
+<p>
+Inserts element <code>value</code> at position <code>pos</code> in <code>table</code>,
+shifting up other elements to open space, if necessary.
+The default value for <code>pos</code> is <code>n+1</code>,
+where <code>n</code> is the length of the table (see <a href="#2.5.5">&sect;2.5.5</a>),
+so that a call <code>table.insert(t,x)</code> inserts <code>x</code> at the end
+of table <code>t</code>.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-table.maxn"><code>table.maxn (table)</code></a></h3>
+
+
+<p>
+Returns the largest positive numerical index of the given table,
+or zero if the table has no positive numerical indices.
+(To do its job this function does a linear traversal of
+the whole table.) 
+
+
+
+
+<p>
+<hr><h3><a name="pdf-table.remove"><code>table.remove (table [, pos])</code></a></h3>
+
+
+<p>
+Removes from <code>table</code> the element at position <code>pos</code>,
+shifting down other elements to close the space, if necessary.
+Returns the value of the removed element.
+The default value for <code>pos</code> is <code>n</code>,
+where <code>n</code> is the length of the table,
+so that a call <code>table.remove(t)</code> removes the last element
+of table <code>t</code>.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-table.sort"><code>table.sort (table [, comp])</code></a></h3>
+Sorts table elements in a given order, <em>in-place</em>,
+from <code>table[1]</code> to <code>table[n]</code>,
+where <code>n</code> is the length of the table.
+If <code>comp</code> is given,
+then it must be a function that receives two table elements,
+and returns true
+when the first is less than the second
+(so that <code>not comp(a[i+1],a[i])</code> will be true after the sort).
+If <code>comp</code> is not given,
+then the standard Lua operator <code>&lt;</code> is used instead.
+
+
+<p>
+The sort algorithm is not stable;
+that is, elements considered equal by the given order
+may have their relative positions changed by the sort.

+<h2>5.7 - <a name="5.7">Input and Output Facilities</a></h2>
+
+<p>
+The I/O library provides two different styles for file manipulation.
+The first one uses implicit file descriptors;
+that is, there are operations to set a default input file and a
+default output file,
+and all input/output operations are over these default files.
+The second style uses explicit file descriptors.
+
+
+<p>
+When using implicit file descriptors,
+all operations are supplied by table <a name="pdf-io"><code>io</code></a>.
+When using explicit file descriptors,
+the operation <a href="#pdf-io.open"><code>io.open</code></a> returns a file descriptor
+and then all operations are supplied as methods of the file descriptor.
+
+
+<p>
+The table <code>io</code> also provides
+three predefined file descriptors with their usual meanings from C:
+<a name="pdf-io.stdin"><code>io.stdin</code></a>, <a name="pdf-io.stdout"><code>io.stdout</code></a>, and <a name="pdf-io.stderr"><code>io.stderr</code></a>.
+The I/O library never closes these files.
+
+
+<p>
+Unless otherwise stated,
+all I/O functions return <b>nil</b> on failure
+(plus an error message as a second result and
+a system-dependent error code as a third result)
+and some value different from <b>nil</b> on success.
+
+
+<p>
+<hr><h3><a name="pdf-io.close"><code>io.close ([file])</code></a></h3>
+
+
+<p>
+Equivalent to <code>file:close()</code>.
+Without a <code>file</code>, closes the default output file.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-io.flush"><code>io.flush ()</code></a></h3>
+
+
+<p>
+Equivalent to <code>file:flush</code> over the default output file.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-io.input"><code>io.input ([file])</code></a></h3>
+
+
+<p>
+When called with a file name, it opens the named file (in text mode),
+and sets its handle as the default input file.
+When called with a file handle,
+it simply sets this file handle as the default input file.
+When called without parameters,
+it returns the current default input file.
+
+
+<p>
+In case of errors this function raises the error,
+instead of returning an error code.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-io.lines"><code>io.lines ([filename])</code></a></h3>
+
+
+<p>
+Opens the given file name in read mode
+and returns an iterator function that,
+each time it is called,
+returns a new line from the file.
+Therefore, the construction
+
+<pre>
+     for line in io.lines(filename) do <em>body</em> end
+</pre><p>
+will iterate over all lines of the file.
+When the iterator function detects the end of file,
+it returns <b>nil</b> (to finish the loop) and automatically closes the file.
+
+
+<p>
+The call <code>io.lines()</code> (with no file name) is equivalent
+to <code>io.input():lines()</code>;
+that is, it iterates over the lines of the default input file.
+In this case it does not close the file when the loop ends.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-io.open"><code>io.open (filename [, mode])</code></a></h3>
+
+
+<p>
+This function opens a file,
+in the mode specified in the string <code>mode</code>.
+It returns a new file handle,
+or, in case of errors, <b>nil</b> plus an error message.
+
+
+<p>
+The <code>mode</code> string can be any of the following:
+
+<ul>
+<li><b>"r":</b> read mode (the default);</li>
+<li><b>"w":</b> write mode;</li>
+<li><b>"a":</b> append mode;</li>
+<li><b>"r+":</b> update mode, all previous data is preserved;</li>
+<li><b>"w+":</b> update mode, all previous data is erased;</li>
+<li><b>"a+":</b> append update mode, previous data is preserved,
+  writing is only allowed at the end of file.</li>
+</ul><p>
+The <code>mode</code> string can also have a '<code>b</code>' at the end,
+which is needed in some systems to open the file in binary mode.
+This string is exactly what is used in the
+standard&nbsp;C function <code>fopen</code>.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-io.output"><code>io.output ([file])</code></a></h3>
+
+
+<p>
+Similar to <a href="#pdf-io.input"><code>io.input</code></a>, but operates over the default output file.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-io.popen"><code>io.popen (prog [, mode])</code></a></h3>
+
+
+<p>
+Starts program <code>prog</code> in a separated process and returns
+a file handle that you can use to read data from this program
+(if <code>mode</code> is <code>"r"</code>, the default)
+or to write data to this program
+(if <code>mode</code> is <code>"w"</code>).
+
+
+<p>
+This function is system dependent and is not available
+on all platforms.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-io.read"><code>io.read (&middot;&middot;&middot;)</code></a></h3>
+
+
+<p>
+Equivalent to <code>io.input():read</code>.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-io.tmpfile"><code>io.tmpfile ()</code></a></h3>
+
+
+<p>
+Returns a handle for a temporary file.
+This file is opened in update mode
+and it is automatically removed when the program ends.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-io.type"><code>io.type (obj)</code></a></h3>
+
+
+<p>
+Checks whether <code>obj</code> is a valid file handle.
+Returns the string <code>"file"</code> if <code>obj</code> is an open file handle,
+<code>"closed file"</code> if <code>obj</code> is a closed file handle,
+or <b>nil</b> if <code>obj</code> is not a file handle.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-io.write"><code>io.write (&middot;&middot;&middot;)</code></a></h3>
+
+
+<p>
+Equivalent to <code>io.output():write</code>.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-file:close"><code>file:close ()</code></a></h3>
+
+
+<p>
+Closes <code>file</code>.
+Note that files are automatically closed when
+their handles are garbage collected,
+but that takes an unpredictable amount of time to happen.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-file:flush"><code>file:flush ()</code></a></h3>
+
+
+<p>
+Saves any written data to <code>file</code>.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-file:lines"><code>file:lines ()</code></a></h3>
+
+
+<p>
+Returns an iterator function that,
+each time it is called,
+returns a new line from the file.
+Therefore, the construction
+
+<pre>
+     for line in file:lines() do <em>body</em> end
+</pre><p>
+will iterate over all lines of the file.
+(Unlike <a href="#pdf-io.lines"><code>io.lines</code></a>, this function does not close the file
+when the loop ends.)
+
+
+
+
+<p>
+<hr><h3><a name="pdf-file:read"><code>file:read (&middot;&middot;&middot;)</code></a></h3>
+
+
+<p>
+Reads the file <code>file</code>,
+according to the given formats, which specify what to read.
+For each format,
+the function returns a string (or a number) with the characters read,
+or <b>nil</b> if it cannot read data with the specified format.
+When called without formats,
+it uses a default format that reads the entire next line
+(see below).
+
+
+<p>
+The available formats are
+
+<ul>
+
+<li><b>"*n":</b>
+reads a number;
+this is the only format that returns a number instead of a string.
+</li>
+
+<li><b>"*a":</b>
+reads the whole file, starting at the current position.
+On end of file, it returns the empty string.
+</li>
+
+<li><b>"*l":</b>
+reads the next line (skipping the end of line),
+returning <b>nil</b> on end of file.
+This is the default format.
+</li>
+
+<li><b><em>number</em>:</b>
+reads a string with up to this number of characters,
+returning <b>nil</b> on end of file.
+If number is zero,
+it reads nothing and returns an empty string,
+or <b>nil</b> on end of file.
+</li>
+
+</ul>
+
+
+
+<p>
+<hr><h3><a name="pdf-file:seek"><code>file:seek ([whence] [, offset])</code></a></h3>
+
+
+<p>
+Sets and gets the file position,
+measured from the beginning of the file,
+to the position given by <code>offset</code> plus a base
+specified by the string <code>whence</code>, as follows:
+
+<ul>
+<li><b>"set":</b> base is position 0 (beginning of the file);</li>
+<li><b>"cur":</b> base is current position;</li>
+<li><b>"end":</b> base is end of file;</li>
+</ul><p>
+In case of success, function <code>seek</code> returns the final file position,
+measured in bytes from the beginning of the file.
+If this function fails, it returns <b>nil</b>,
+plus a string describing the error.
+
+
+<p>
+The default value for <code>whence</code> is <code>"cur"</code>,
+and for <code>offset</code> is 0.
+Therefore, the call <code>file:seek()</code> returns the current
+file position, without changing it;
+the call <code>file:seek("set")</code> sets the position to the
+beginning of the file (and returns 0);
+and the call <code>file:seek("end")</code> sets the position to the
+end of the file, and returns its size.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-file:setvbuf"><code>file:setvbuf (mode [, size])</code></a></h3>
+
+
+<p>
+Sets the buffering mode for an output file.
+There are three available modes:
+
+<ul>
+
+<li><b>"no":</b>
+no buffering; the result of any output operation appears immediately.
+</li>
+
+<li><b>"full":</b>
+full buffering; output operation is performed only
+when the buffer is full (or when you explicitly <code>flush</code> the file
+(see <a href="#pdf-io.flush"><code>io.flush</code></a>)).
+</li>
+
+<li><b>"line":</b>
+line buffering; output is buffered until a newline is output
+or there is any input from some special files
+(such as a terminal device).
+</li>
+
+</ul><p>
+For the last two cases, <code>size</code>
+specifies the size of the buffer, in bytes.
+The default is an appropriate size.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-file:write"><code>file:write (&middot;&middot;&middot;)</code></a></h3>
+
+
+<p>
+Writes the value of each of its arguments to
+the <code>file</code>.
+The arguments must be strings or numbers.
+To write other values,
+use <a href="#pdf-tostring"><code>tostring</code></a> or <a href="#pdf-string.format"><code>string.format</code></a> before <code>write</code>.

+<h2>5.8 - <a name="5.8">Operating System Facilities</a></h2>
+
+<p>
+This library is implemented through table <a name="pdf-os"><code>os</code></a>.
+
+
+<p>
+<hr><h3><a name="pdf-os.clock"><code>os.clock ()</code></a></h3>
+
+
+<p>
+Returns an approximation of the amount in seconds of CPU time
+used by the program.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-os.date"><code>os.date ([format [, time]])</code></a></h3>
+
+
+<p>
+Returns a string or a table containing date and time,
+formatted according to the given string <code>format</code>.
+
+
+<p>
+If the <code>time</code> argument is present,
+this is the time to be formatted
+(see the <a href="#pdf-os.time"><code>os.time</code></a> function for a description of this value).
+Otherwise, <code>date</code> formats the current time.
+
+
+<p>
+If <code>format</code> starts with '<code>!</code>',
+then the date is formatted in Coordinated Universal Time.
+After this optional character,
+if <code>format</code> is the string "<code>*t</code>",
+then <code>date</code> returns a table with the following fields:
+<code>year</code> (four digits), <code>month</code> (1--12), <code>day</code> (1--31),
+<code>hour</code> (0--23), <code>min</code> (0--59), <code>sec</code> (0--61),
+<code>wday</code> (weekday, Sunday is&nbsp;1),
+<code>yday</code> (day of the year),
+and <code>isdst</code> (daylight saving flag, a boolean).
+
+
+<p>
+If <code>format</code> is not "<code>*t</code>",
+then <code>date</code> returns the date as a string,
+formatted according to the same rules as the C&nbsp;function <code>strftime</code>.
+
+
+<p>
+When called without arguments,
+<code>date</code> returns a reasonable date and time representation that depends on
+the host system and on the current locale
+(that is, <code>os.date()</code> is equivalent to <code>os.date("%c")</code>).
+
+
+
+
+<p>
+<hr><h3><a name="pdf-os.difftime"><code>os.difftime (t2, t1)</code></a></h3>
+
+
+<p>
+Returns the number of seconds from time <code>t1</code> to time <code>t2</code>.
+In POSIX, Windows, and some other systems,
+this value is exactly <code>t2</code><em>-</em><code>t1</code>.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-os.execute"><code>os.execute ([command])</code></a></h3>
+
+
+<p>
+This function is equivalent to the C&nbsp;function <code>system</code>.
+It passes <code>command</code> to be executed by an operating system shell.
+It returns a status code, which is system-dependent.
+If <code>command</code> is absent, then it returns nonzero if a shell is available
+and zero otherwise.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-os.exit"><code>os.exit ([code])</code></a></h3>
+
+
+<p>
+Calls the C&nbsp;function <code>exit</code>,
+with an optional <code>code</code>,
+to terminate the host program.
+The default value for <code>code</code> is the success code.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-os.getenv"><code>os.getenv (varname)</code></a></h3>
+
+
+<p>
+Returns the value of the process environment variable <code>varname</code>,
+or <b>nil</b> if the variable is not defined.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-os.remove"><code>os.remove (filename)</code></a></h3>
+
+
+<p>
+Deletes the file or directory with the given name.
+Directories must be empty to be removed.
+If this function fails, it returns <b>nil</b>,
+plus a string describing the error.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-os.rename"><code>os.rename (oldname, newname)</code></a></h3>
+
+
+<p>
+Renames file or directory named <code>oldname</code> to <code>newname</code>.
+If this function fails, it returns <b>nil</b>,
+plus a string describing the error.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-os.setlocale"><code>os.setlocale (locale [, category])</code></a></h3>
+
+
+<p>
+Sets the current locale of the program.
+<code>locale</code> is a string specifying a locale;
+<code>category</code> is an optional string describing which category to change:
+<code>"all"</code>, <code>"collate"</code>, <code>"ctype"</code>,
+<code>"monetary"</code>, <code>"numeric"</code>, or <code>"time"</code>;
+the default category is <code>"all"</code>.
+The function returns the name of the new locale,
+or <b>nil</b> if the request cannot be honored.
+
+
+<p>
+If <code>locale</code> is the empty string,
+the current locale is set to an implementation-defined native locale.
+If <code>locale</code> is the string "<code>C</code>",
+the current locale is set to the standard C locale.
+
+
+<p>
+When called with <b>nil</b> as the first argument,
+this function only returns the name of the current locale
+for the given category.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-os.time"><code>os.time ([table])</code></a></h3>
+
+
+<p>
+Returns the current time when called without arguments,
+or a time representing the date and time specified by the given table.
+This table must have fields <code>year</code>, <code>month</code>, and <code>day</code>,
+and may have fields <code>hour</code>, <code>min</code>, <code>sec</code>, and <code>isdst</code>
+(for a description of these fields, see the <a href="#pdf-os.date"><code>os.date</code></a> function).
+
+
+<p>
+The returned value is a number, whose meaning depends on your system.
+In POSIX, Windows, and some other systems, this number counts the number
+of seconds since some given start time (the "epoch").
+In other systems, the meaning is not specified,
+and the number returned by <code>time</code> can be used only as an argument to
+<code>date</code> and <code>difftime</code>.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-os.tmpname"><code>os.tmpname ()</code></a></h3>
+
+
+<p>
+Returns a string with a file name that can
+be used for a temporary file.
+The file must be explicitly opened before its use
+and explicitly removed when no longer needed.
+
+
+<p>
+On some systems (POSIX),
+this function also creates a file with that name,
+to avoid security risks.
+(Someone else might create the file with wrong permissions
+in the time between getting the name and creating the file.)
+You still have to open the file to use it
+and to remove it (even if you do not use it).
+
+
+<p>
+When possible,
+you may prefer to use <a href="#pdf-io.tmpfile"><code>io.tmpfile</code></a>,
+which automatically removes the file when the program ends.

+<h2>5.9 - <a name="5.9">The Debug Library</a></h2>
+
+<p>
+This library provides
+the functionality of the debug interface to Lua programs.
+You should exert care when using this library.
+The functions provided here should be used exclusively for debugging
+and similar tasks, such as profiling.
+Please resist the temptation to use them as a
+usual programming tool:
+they can be very slow.
+Moreover, several of these functions
+violate some assumptions about Lua code
+(e.g., that variables local to a function
+cannot be accessed from outside or
+that userdata metatables cannot be changed by Lua code)
+and therefore can compromise otherwise secure code.
+
+
+<p>
+All functions in this library are provided
+inside the <a name="pdf-debug"><code>debug</code></a> table.
+All functions that operate over a thread
+have an optional first argument which is the
+thread to operate over.
+The default is always the current thread.
+
+
+<p>
+<hr><h3><a name="pdf-debug.debug"><code>debug.debug ()</code></a></h3>
+
+
+<p>
+Enters an interactive mode with the user,
+running each string that the user enters.
+Using simple commands and other debug facilities,
+the user can inspect global and local variables,
+change their values, evaluate expressions, and so on.
+A line containing only the word <code>cont</code> finishes this function,
+so that the caller continues its execution.
+
+
+<p>
+Note that commands for <code>debug.debug</code> are not lexically nested
+within any function, and so have no direct access to local variables.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-debug.getfenv"><code>debug.getfenv (o)</code></a></h3>
+Returns the environment of object <code>o</code>.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-debug.gethook"><code>debug.gethook ([thread])</code></a></h3>
+
+
+<p>
+Returns the current hook settings of the thread, as three values:
+the current hook function, the current hook mask,
+and the current hook count
+(as set by the <a href="#pdf-debug.sethook"><code>debug.sethook</code></a> function).
+
+
+
+
+<p>
+<hr><h3><a name="pdf-debug.getinfo"><code>debug.getinfo ([thread,] function [, what])</code></a></h3>
+
+
+<p>
+Returns a table with information about a function.
+You can give the function directly,
+or you can give a number as the value of <code>function</code>,
+which means the function running at level <code>function</code> of the call stack
+of the given thread:
+level&nbsp;0 is the current function (<code>getinfo</code> itself);
+level&nbsp;1 is the function that called <code>getinfo</code>;
+and so on.
+If <code>function</code> is a number larger than the number of active functions,
+then <code>getinfo</code> returns <b>nil</b>.
+
+
+<p>
+The returned table can contain all the fields returned by <a href="#lua_getinfo"><code>lua_getinfo</code></a>,
+with the string <code>what</code> describing which fields to fill in.
+The default for <code>what</code> is to get all information available,
+except the table of valid lines.
+If present,
+the option '<code>f</code>'
+adds a field named <code>func</code> with the function itself.
+If present,
+the option '<code>L</code>'
+adds a field named <code>activelines</code> with the table of
+valid lines.
+
+
+<p>
+For instance, the expression <code>debug.getinfo(1,"n").name</code> returns
+a table with a name for the current function,
+if a reasonable name can be found,
+and the expression <code>debug.getinfo(print)</code>
+returns a table with all available information
+about the <a href="#pdf-print"><code>print</code></a> function.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-debug.getlocal"><code>debug.getlocal ([thread,] level, local)</code></a></h3>
+
+
+<p>
+This function returns the name and the value of the local variable
+with index <code>local</code> of the function at level <code>level</code> of the stack.
+(The first parameter or local variable has index&nbsp;1, and so on,
+until the last active local variable.)
+The function returns <b>nil</b> if there is no local
+variable with the given index,
+and raises an error when called with a <code>level</code> out of range.
+(You can call <a href="#pdf-debug.getinfo"><code>debug.getinfo</code></a> to check whether the level is valid.)
+
+
+<p>
+Variable names starting with '<code>(</code>' (open parentheses)
+represent internal variables
+(loop control variables, temporaries, and C&nbsp;function locals).
+
+
+
+
+<p>
+<hr><h3><a name="pdf-debug.getmetatable"><code>debug.getmetatable (object)</code></a></h3>
+
+
+<p>
+Returns the metatable of the given <code>object</code>
+or <b>nil</b> if it does not have a metatable.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-debug.getregistry"><code>debug.getregistry ()</code></a></h3>
+
+
+<p>
+Returns the registry table (see <a href="#3.5">&sect;3.5</a>).
+
+
+
+
+<p>
+<hr><h3><a name="pdf-debug.getupvalue"><code>debug.getupvalue (func, up)</code></a></h3>
+
+
+<p>
+This function returns the name and the value of the upvalue
+with index <code>up</code> of the function <code>func</code>.
+The function returns <b>nil</b> if there is no upvalue with the given index.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-debug.setfenv"><code>debug.setfenv (object, table)</code></a></h3>
+
+
+<p>
+Sets the environment of the given <code>object</code> to the given <code>table</code>.
+Returns <code>object</code>.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-debug.sethook"><code>debug.sethook ([thread,] hook, mask [, count])</code></a></h3>
+
+
+<p>
+Sets the given function as a hook.
+The string <code>mask</code> and the number <code>count</code> describe
+when the hook will be called.
+The string mask may have the following characters,
+with the given meaning:
+
+<ul>
+<li><b><code>"c"</code>:</b> the hook is called every time Lua calls a function;</li>
+<li><b><code>"r"</code>:</b> the hook is called every time Lua returns from a function;</li>
+<li><b><code>"l"</code>:</b> the hook is called every time Lua enters a new line of code.</li>
+</ul><p>
+With a <code>count</code> different from zero,
+the hook is called after every <code>count</code> instructions.
+
+
+<p>
+When called without arguments,
+<a href="#pdf-debug.sethook"><code>debug.sethook</code></a> turns off the hook.
+
+
+<p>
+When the hook is called, its first parameter is a string
+describing the event that has triggered its call:
+<code>"call"</code>, <code>"return"</code> (or <code>"tail return"</code>,
+when simulating a return from a tail call),
+<code>"line"</code>, and <code>"count"</code>.
+For line events,
+the hook also gets the new line number as its second parameter.
+Inside a hook,
+you can call <code>getinfo</code> with level&nbsp;2 to get more information about
+the running function
+(level&nbsp;0 is the <code>getinfo</code> function,
+and level&nbsp;1 is the hook function),
+unless the event is <code>"tail return"</code>.
+In this case, Lua is only simulating the return,
+and a call to <code>getinfo</code> will return invalid data.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-debug.setlocal"><code>debug.setlocal ([thread,] level, local, value)</code></a></h3>
+
+
+<p>
+This function assigns the value <code>value</code> to the local variable
+with index <code>local</code> of the function at level <code>level</code> of the stack.
+The function returns <b>nil</b> if there is no local
+variable with the given index,
+and raises an error when called with a <code>level</code> out of range.
+(You can call <code>getinfo</code> to check whether the level is valid.)
+Otherwise, it returns the name of the local variable.
+
+
+
+
+<p>
+<hr><h3><a name="pdf-debug.setmetatable"><code>debug.setmetatable (object, table)</code></a></h3>
+

+<p>
+Sets the metatable for the given <code>object</code> to the given <code>table</code>
+(which can be <b>nil</b>).
+
+
+

+<h1>6 - <a name="6">Lua Stand-alone</a></h1>
+
+<p>
+Although Lua has been designed as an extension language,
+to be embedded in a host C&nbsp;program,
+it is also frequently used as a stand-alone language.
+An interpreter for Lua as a stand-alone language,
+called simply <code>lua</code>,
+is provided with the standard distribution.
+The stand-alone interpreter includes
+all standard libraries, including the debug library.
+Its usage is:
+
+<pre>
+     lua [options] [script [args]]
+</pre><p>
+The options are:
+
+<ul>
+<li><b><code>-e <em>stat</em></code>:</b> executes string <em>stat</em>;</li>
+<li><b><code>-l <em>mod</em></code>:</b> "requires" <em>mod</em>;</li>
+<li><b><code>-i</code>:</b> enters interactive mode after running <em>script</em>;</li>
+<li><b><code>-v</code>:</b> prints version information;</li>
+<li><b><code>--</code>:</b> stops handling options;</li>
+<li><b><code>-</code>:</b> executes <code>stdin</code> as a file and stops handling options.</li>
+</ul><p>
+After handling its options, <code>lua</code> runs the given <em>script</em>,
+passing to it the given <em>args</em> as string arguments.
+When called without arguments,
+<code>lua</code> behaves as <code>lua -v -i</code>
+when the standard input (<code>stdin</code>) is a terminal,
+and as <code>lua -</code> otherwise.
+
+
+<p>
+Before running any argument,
+the interpreter checks for an environment variable <a name="pdf-LUA_INIT"><code>LUA_INIT</code></a>.
+If its format is <code>@<em>filename</em></code>,
+then <code>lua</code> executes the file.
+Otherwise, <code>lua</code> executes the string itself.
+
+
+<p>
+All options are handled in order, except <code>-i</code>.
+For instance, an invocation like
+
+<pre>
+     $ lua -e'a=1' -e 'print(a)' script.lua
+</pre><p>
+will first set <code>a</code> to 1, then print the value of <code>a</code> (which is '<code>1</code>'),
+and finally run the file <code>script.lua</code> with no arguments.
+(Here <code>$</code> is the shell prompt. Your prompt may be different.)
+
+
+<p>
+Before starting to run the script,
+<code>lua</code> collects all arguments in the command line
+in a global table called <code>arg</code>.
+The script name is stored at index 0,
+the first argument after the script name goes to index 1,
+and so on.
+Any arguments before the script name
+(that is, the interpreter name plus the options)
+go to negative indices.
+For instance, in the call
+
+<pre>
+     $ lua -la b.lua t1 t2
+</pre><p>
+the interpreter first runs the file <code>a.lua</code>,
+then creates a table
+
+<pre>
+     arg = { [-2] = "lua", [-1] = "-la",
+             [0] = "b.lua",
+             [1] = "t1", [2] = "t2" }
+</pre><p>
+and finally runs the file <code>b.lua</code>.
+The script is called with <code>arg[1]</code>, <code>arg[2]</code>, &middot;&middot;&middot;
+as arguments;
+it can also access these arguments with the vararg expression '<code>...</code>'.
+
+
+<p>
+In interactive mode,
+if you write an incomplete statement,
+the interpreter waits for its completion
+by issuing a different prompt.
+
+
+<p>
+If the global variable <a name="pdf-_PROMPT"><code>_PROMPT</code></a> contains a string,
+then its value is used as the prompt.
+Similarly, if the global variable <a name="pdf-_PROMPT2"><code>_PROMPT2</code></a> contains a string,
+its value is used as the secondary prompt
+(issued during incomplete statements).
+Therefore, both prompts can be changed directly on the command line
+or in any Lua programs by assigning to <code>_PROMPT</code>.
+See the next example:
+
+<pre>
+     $ lua -e"_PROMPT='myprompt&gt; '" -i
+</pre><p>
+(The outer pair of quotes is for the shell,
+the inner pair is for Lua.)
+Note the use of <code>-i</code> to enter interactive mode;
+otherwise,
+the program would just end silently
+right after the assignment to <code>_PROMPT</code>.
+
+
+<p>
+To allow the use of Lua as a
+script interpreter in Unix systems,
+the stand-alone interpreter skips
+the first line of a chunk if it starts with <code>#</code>.
+Therefore, Lua scripts can be made into executable programs
+by using <code>chmod +x</code> and the&nbsp;<code>#!</code> form,
+as in
+
+<pre>
+     #!/usr/local/bin/lua
+</pre><p>
+(Of course,
+the location of the Lua interpreter may be different in your machine.
+If <code>lua</code> is in your <code>PATH</code>,
+then 
+
+<pre>
+     #!/usr/bin/env lua
+</pre><p>
+is a more portable solution.) 
+

+<h1>7 - <a name="7">Incompatibilities with the Previous Version</a></h1>
+
+<p>
+Here we list the incompatibilities that you may find when moving a program
+from Lua&nbsp;5.0 to Lua&nbsp;5.1.
+You can avoid most of the incompatibilities compiling Lua with
+appropriate options (see file <code>luaconf.h</code>).
+However,
+all these compatibility options will be removed in the next version of Lua.
+
+
+
+<h2>7.1 - <a name="7.1">Changes in the Language</a></h2>
+<ul>
+
+<li>
+The vararg system changed from the pseudo-argument <code>arg</code> with a
+table with the extra arguments to the vararg expression.
+(See compile-time option <code>LUA_COMPAT_VARARG</code> in <code>luaconf.h</code>.)
+</li>
+
+<li>
+There was a subtle change in the scope of the implicit
+variables of the <b>for</b> statement and for the <b>repeat</b> statement.
+</li>
+
+<li>
+The long string/long comment syntax (<code>[[<em>string</em>]]</code>)
+does not allow nesting.
+You can use the new syntax (<code>[=[<em>string</em>]=]</code>) in these cases.
+(See compile-time option <code>LUA_COMPAT_LSTR</code> in <code>luaconf.h</code>.)
+</li>
+
+</ul>
+
+
+
+
+<h2>7.2 - <a name="7.2">Changes in the Libraries</a></h2>
+<ul>
+
+<li>
+Function <code>string.gfind</code> was renamed <a href="#pdf-string.gmatch"><code>string.gmatch</code></a>.
+(See compile-time option <code>LUA_COMPAT_GFIND</code> in <code>luaconf.h</code>.)
+</li>
+
+<li>
+When <a href="#pdf-string.gsub"><code>string.gsub</code></a> is called with a function as its
+third argument,
+whenever this function returns <b>nil</b> or <b>false</b> the
+replacement string is the whole match,
+instead of the empty string.
+</li>
+
+<li>
+Function <code>table.setn</code> was deprecated.
+Function <code>table.getn</code> corresponds
+to the new length operator (<code>#</code>);
+use the operator instead of the function.
+(See compile-time option <code>LUA_COMPAT_GETN</code> in <code>luaconf.h</code>.)
+</li>
+
+<li>
+Function <code>loadlib</code> was renamed <a href="#pdf-package.loadlib"><code>package.loadlib</code></a>.
+(See compile-time option <code>LUA_COMPAT_LOADLIB</code> in <code>luaconf.h</code>.)
+</li>
+
+<li>
+Function <code>math.mod</code> was renamed <a href="#pdf-math.fmod"><code>math.fmod</code></a>.
+(See compile-time option <code>LUA_COMPAT_MOD</code> in <code>luaconf.h</code>.)
+</li>
+
+<li>
+Functions <code>table.foreach</code> and <code>table.foreachi</code> are deprecated.
+You can use a for loop with <code>pairs</code> or <code>ipairs</code> instead.
+</li>
+
+<li>
+There were substantial changes in function <a href="#pdf-require"><code>require</code></a> due to
+the new module system.
+However, the new behavior is mostly compatible with the old,
+but <code>require</code> gets the path from <a href="#pdf-package.path"><code>package.path</code></a> instead
+of from <code>LUA_PATH</code>.
+</li>
+
+<li>
+Function <a href="#pdf-collectgarbage"><code>collectgarbage</code></a> has different arguments.
+Function <code>gcinfo</code> is deprecated;
+use <code>collectgarbage("count")</code> instead.
+</li>
+
+</ul>
+
+
+
+
+<h2>7.3 - <a name="7.3">Changes in the API</a></h2>
+<ul>
+
+<li>
+The <code>luaopen_*</code> functions (to open libraries)
+cannot be called directly,
+like a regular C function.
+They must be called through Lua,
+like a Lua function.
+</li>
+
+<li>
+Function <code>lua_open</code> was replaced by <a href="#lua_newstate"><code>lua_newstate</code></a> to
+allow the user to set a memory-allocation function.
+You can use <a href="#luaL_newstate"><code>luaL_newstate</code></a> from the standard library to
+create a state with a standard allocation function
+(based on <code>realloc</code>).
+</li>
+
+<li>
+Functions <code>luaL_getn</code> and <code>luaL_setn</code>
+(from the auxiliary library) are deprecated.
+Use <a href="#lua_objlen"><code>lua_objlen</code></a> instead of <code>luaL_getn</code>
+and nothing instead of <code>luaL_setn</code>.
+</li>
+
+<li>
+Function <code>luaL_openlib</code> was replaced by <a href="#luaL_register"><code>luaL_register</code></a>.
+</li>
+
+<li>
+Function <code>luaL_checkudata</code> now throws an error when the given value
+is not a userdata of the expected type.
+(In Lua&nbsp;5.0 it returned <code>NULL</code>.)
+</li>
+
+</ul>
+
+
+

+** least half the slots between 0 and n are in use.
+** Hash uses a mix of chained scatter table with Brent's variation.

+** Hence even when the load factor reaches 100%, performance remains good.

Subject: [PATCH 052/435] feat: add core WoW Lua API functions for addon
 development

Add 13 WoW-compatible Lua API functions that addons can call:

Unit API: UnitName, UnitHealth, UnitHealthMax, UnitPower, UnitPowerMax,
UnitLevel, UnitExists, UnitIsDead, UnitClass (supports "player",
"target", "focus", "pet" unit IDs)

Game API: GetMoney, IsInGroup, IsInRaid, GetPlayerMapPosition

Updated HelloWorld addon to demonstrate querying player state.

Subject: [PATCH 053/435] feat: add WoW event system for Lua addons
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Implement the WoW-compatible event system that lets addons react to
gameplay events in real-time:

- RegisterEvent(eventName, handler) — register a Lua function for an event
- UnregisterEvent(eventName, handler) — remove a handler
- fireEvent() dispatches events to all registered handlers with args

Currently fired events:
- PLAYER_ENTERING_WORLD — after addons load and world entry completes
- PLAYER_LEAVING_WORLD — before logout/disconnect

Events are stored in a __WoweeEvents Lua table, dispatched via
LuaEngine::fireEvent() which is called from AddonManager::fireEvent().
Error handling logs Lua errors without crashing.

Updated HelloWorld addon to use RegisterEvent for world entry/exit.

Subject: [PATCH 054/435] feat: fire CHAT_MSG_* events to Lua addons for all
 chat types

Wire chat messages to the addon event system via AddonChatCallback.
Every chat message now fires the corresponding WoW event:

- CHAT_MSG_SAY, CHAT_MSG_YELL, CHAT_MSG_WHISPER
- CHAT_MSG_PARTY, CHAT_MSG_GUILD, CHAT_MSG_OFFICER
- CHAT_MSG_RAID, CHAT_MSG_RAID_WARNING, CHAT_MSG_BATTLEGROUND
- CHAT_MSG_SYSTEM, CHAT_MSG_CHANNEL, CHAT_MSG_EMOTE

Event handlers receive (eventName, message, senderName) arguments.
Addons can now filter, react to, or log chat messages in real-time.

Subject: [PATCH 055/435] feat: add action WoW API functions for Lua addons
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add 5 more essential WoW API functions for addon development:

- SendChatMessage(msg, type, lang, target) — send chat messages
  (SAY, YELL, WHISPER, PARTY, GUILD, OFFICER, RAID, BG)
- CastSpellByName(name) — cast highest rank of named spell
- IsSpellKnown(spellId) — check if player knows a spell
- GetSpellCooldown(nameOrId) — get remaining cooldown
- HasTarget() — check if player has a target

Total WoW API surface: 18 functions across Unit, Game, and Action
categories. Addons can now query state, react to events, send
messages, and cast spells.

Subject: [PATCH 056/435] feat: add WoW utility functions and SlashCmdList for
 addon slash commands
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Utility functions:
- strsplit(delim, str), strtrim(str), wipe(table)
- date(format), time() — safe replacements for removed os.date/os.time
- format (alias for string.format), tinsert/tremove (table aliases)

SlashCmdList system:
- Addons can register custom slash commands via the standard WoW pattern:
  SLASH_MYADDON1 = "/myaddon"
  SlashCmdList["MYADDON"] = function(args) ... end
- Chat input checks SlashCmdList before built-in commands
- dispatchSlashCommand() iterates SLASH_<NAME>1..9 globals to match

Total WoW API surface: 23 functions + SlashCmdList + 14 events.

Subject: [PATCH 057/435] feat: add CreateFrame with RegisterEvent/SetScript
 for WoW addon pattern
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Implement the core WoW frame system that nearly all addons use:

- CreateFrame(type, name, parent, template) — creates a frame table
  with metatable methods, optionally registered as a global by name
- frame:RegisterEvent(event) — register frame for event dispatch
- frame:UnregisterEvent(event) — unregister
- frame:SetScript(type, handler) — set OnEvent/OnUpdate/etc handlers
- frame:GetScript(type) — retrieve handlers
- frame:Show()/Hide()/IsShown()/IsVisible() — visibility state
- frame:GetName() — return frame name

Event dispatch now fires both global RegisterEvent handlers AND
frame OnEvent scripts, matching WoW's dual dispatch model.

Updated HelloWorld to use standard WoW addon pattern:
  local f = CreateFrame("Frame", "MyFrame")
  f:RegisterEvent("PLAYER_ENTERING_WORLD")
  f:SetScript("OnEvent", function(self, event, ...) end)

Subject: [PATCH 058/435] feat: fire PLAYER_TARGET_CHANGED and PLAYER_LEVEL_UP
 addon events
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add a generic AddonEventCallback to GameHandler for firing named events
with string arguments directly from game logic. Wire it to the addon
system in Application.

New events fired:
- PLAYER_TARGET_CHANGED — when target is set or cleared
- PLAYER_LEVEL_UP(newLevel) — on level up

The generic callback pattern makes it easy to add more events from
game_handler.cpp without touching Application/AddonManager code.
Total addon events: 16 (2 world + 12 chat + 2 gameplay).

Subject: [PATCH 060/435] feat: add OnUpdate frame script for per-frame addon
 callbacks

Frames can now set an OnUpdate script that fires every frame with
the elapsed time as an argument. This enables addon timers, polling,
and animations.

  local f = CreateFrame("Frame")
  f:SetScript("OnUpdate", function(self, elapsed)
      -- called every frame with deltaTime
  end)

OnUpdate only fires for visible frames (frame:Hide() pauses it).
Tracked in __WoweeOnUpdateFrames table, dispatched via
LuaEngine::dispatchOnUpdate() called from the Application main loop.

Subject: [PATCH 061/435] feat: add C_Timer.After and C_Timer.NewTicker for Lua
 addons
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Implement WoW's C_Timer API used by most modern addons:

- C_Timer.After(seconds, callback) — fire callback after delay
- C_Timer.NewTicker(seconds, callback, iterations) — repeating timer
  with optional iteration limit and :Cancel() method

Implemented in pure Lua using a hidden OnUpdate frame that
auto-hides when no timers are pending (zero overhead when idle).

Example:
  C_Timer.After(3, function() print("3 sec later!") end)
  local ticker = C_Timer.NewTicker(1, function() print("tick") end, 5)

Subject: [PATCH 063/435] feat: add SavedVariables persistence for Lua addons

Addons can now persist data across sessions using the standard WoW
SavedVariables pattern:

1. Declare in .toc: ## SavedVariables: MyAddonDB
2. Use the global in Lua: MyAddonDB = MyAddonDB or {default = true}
3. Data is automatically saved on logout and restored on next login

Implementation:
- TocFile::getSavedVariables() parses comma-separated variable names
- LuaEngine::loadSavedVariables() executes saved .lua file to restore globals
- LuaEngine::saveSavedVariables() serializes Lua tables/values to valid Lua
- Serializer handles tables (nested), strings, numbers, booleans, nil
- Save triggered on PLAYER_LEAVING_WORLD and AddonManager::shutdown()
- Files stored as <AddonDir>/<AddonName>.lua.saved

Updated HelloWorld addon to track login count across sessions.

Subject: [PATCH 064/435] fix: exclude vendored Lua 5.1.5 from Semgrep security
 scan

The Semgrep security scan was failing because vendored Lua 5.1.5 source
uses strcpy/strncpy which are flagged as insecure C functions. These are
false positives in frozen third-party code that we don't modify.

Added .semgrepignore to exclude all vendored extern/ directories
(lua-5.1.5, imgui, stb, vk-bootstrap, FidelityFX SDKs).

Subject: [PATCH 065/435] feat: add UnitBuff and UnitDebuff API for Lua addons
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Implement the most commonly used buff/debuff query functions:

- UnitBuff(unitId, index) — query the Nth buff on a unit
- UnitDebuff(unitId, index) — query the Nth debuff on a unit

Returns WoW-compatible 11-value tuple: name, rank, icon, count,
debuffType, duration, expirationTime, caster, isStealable,
shouldConsolidate, spellId.

Supports "player" and "target" unit IDs. Essential for buff tracking
addons (WeakAuras-style), healer addons, and combat analysis tools.

Total WoW API: 31 functions.

 finishes loading
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Fire ADDON_LOADED(addonName) after all of an addon's files have been
executed. This is the standard WoW pattern for addon initialization —
addons register for this event to set up defaults after SavedVariables
are loaded:

  local f = CreateFrame("Frame")
  f:RegisterEvent("ADDON_LOADED")
  f:SetScript("OnEvent", function(self, event, name)
      if name == "MyAddon" then
          MyAddonDB = MyAddonDB or {defaults}
      end
  end)

Total addon events: 20.

 introspection
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- GetNumAddOns() — returns count of loaded addons
- GetAddOnInfo(indexOrName) — returns name, title, notes, loadable

Addon info is stored in the Lua registry from the .toc directives
and populated before addon files execute. Useful for addon managers
and compatibility checks between addons.

Total WoW API: 33 functions.

Subject: [PATCH 068/435] feat: add DEFAULT_CHAT_FRAME with AddMessage for
 addon output

Many WoW addons use DEFAULT_CHAT_FRAME:AddMessage(text, r, g, b) to
output colored text to chat. Implemented as a Lua table with AddMessage
that converts RGB floats to WoW color codes and calls print().
Also aliased as ChatFrame1 for compatibility.

Example: DEFAULT_CHAT_FRAME:AddMessage("Hello!", 1, 0.5, 0)

Subject: [PATCH 069/435] feat: add hooksecurefunc, UIParent, and noop stubs
 for addon compat
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- hooksecurefunc(tblOrName, name, hook) — hook any function to run
  additional code after it executes without replacing the original.
  Supports both global and table method forms.

- UIParent, WorldFrame — standard parent frames that many addons
  reference as parents for their own frames.

- Noop stubs: SetDesaturation, SetPortraitTexture, PlaySound,
  PlaySoundFile — prevent errors from addons that call these
  visual/audio functions which don't have implementations yet.

 and more Lua API functions

Add spell icon path resolution via SpellIcon.dbc + Spell.dbc lazy loading,
wired through GameHandler callback. Fix UnitBuff/UnitDebuff to return icon
texture paths instead of nil. Add GetLocale, GetBuildInfo, GetCurrentMapAreaID.

Subject: [PATCH 071/435] feat: add party/raid unit IDs and game events for Lua
 addon system

Extend resolveUnit() to support party1-4, raid1-40, and use resolveUnitGuid
for UnitGUID/UnitIsPlayer/UnitBuff/UnitDebuff (including unitAurasCache for
party member auras). Fire UNIT_HEALTH, UNIT_POWER, UNIT_AURA, UNIT_SPELLCAST_START,
UNIT_SPELLCAST_SUCCEEDED, GROUP_ROSTER_UPDATE, and PARTY_MEMBERS_CHANGED events
to Lua addons from the corresponding packet handlers.

Subject: [PATCH 072/435] feat: fire combat, spell, and cooldown events for Lua
 addon system

Add PLAYER_REGEN_DISABLED/ENABLED (combat enter/leave) via per-frame
edge detection, LEARNED_SPELL_IN_TAB/SPELLS_CHANGED on spell learn/remove,
SPELL_UPDATE_COOLDOWN/ACTIONBAR_UPDATE_COOLDOWN on cooldown finish, and
PLAYER_XP_UPDATE on XP field changes. Total addon events now at 34.

subevent names (SWING_DAMAGE, SPELL_DAMAGE, SPELL_HEAL, etc.), source/dest

Subject: [PATCH 076/435] feat: replace hardcoded state stubs with real game
 state in Lua API

IsMounted, IsFlying, IsSwimming, IsResting, IsFalling, and IsStealthed
now query actual GameHandler state (mount display ID, movement flags,
resting flag, aura list) instead of returning false. Add GetUnitSpeed
for player run speed. Fixes addon conditionals that depend on player
movement/mount/combat state.

Subject: [PATCH 077/435] feat: show quest POI markers on the world map overlay

Add QuestPoi struct and setQuestPois() to WorldMap, render quest objective
markers as cyan circles with golden outlines and quest title labels. Wire
gossipPois_ (from SMSG_QUEST_POI_QUERY_RESPONSE) through GameScreen to the
world map so quest objectives are visible alongside party dots and taxi nodes.

Subject: [PATCH 078/435] feat: add zone change and login sequence events for
 Lua addons

Fire ZONE_CHANGED_NEW_AREA and ZONE_CHANGED when worldStateZoneId changes
in SMSG_INIT_WORLD_STATES. Add VARIABLES_LOADED and PLAYER_LOGIN events in
the addon loading sequence (before PLAYER_ENTERING_WORLD), and fire
PLAYER_ENTERING_WORLD on subsequent world entries (teleport, instance).
Enables zone-aware addons like DBM and quest trackers.

Subject: [PATCH 079/435] fix: correct NPC equipment geoset group assignments
 for gloves and boots
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

NPC character models used wrong geoset groups: gloves were group 3 (300s)
instead of group 4 (400s), boots were group 4 (400s) instead of group 5
(500s), matching the character preview code. Also remove spurious "torso"
geoset from group 5 (conflicted with boots) — chest armor controls only
group 8 (sleeves), not a separate torso visibility group. Fixes NPC
equipment rendering with incorrect body part meshes.

Add UnitAffectingCombat, GetNumRaidMembers, GetNumPartyMembers, UnitInParty,
UnitInRaid, UnitIsUnit, UnitIsFriend, UnitIsEnemy, and UnitCreatureType.
These are commonly used by raid/group addons for party composition checks,
combat state queries, and mob type identification. Total API count now 55.

Subject: [PATCH 081/435] feat: add bid status indicators to auction house UI

Show [Winning] (green) or [Outbid] (red) labels on the Bids tab based on
bidderGuid vs player GUID comparison. Show [Bid] (gold) indicator on the
seller's Auctions tab when someone has placed a bid on their listing.
Improves auction house usability by making bid status visible at a glance.

Add Weather::Type::STORM enum value and wire it from SMSG_WEATHER type 3.
Storm particles are faster (70 units/s vs rain's 50), wind-angled at 15+
units lateral velocity with gusty turbulence, darker blue-grey tint, and
shorter lifetime. Previously storms rendered identically to rain.

Subject: [PATCH 086/435] feat: add LFG role check confirmation popup with
 CMSG_LFG_SET_ROLES

When the dungeon finder initiates a role check (SMSG_LFG_ROLE_CHECK_UPDATE
state=2), show a centered popup with Tank/Healer/DPS checkboxes and
Accept/Leave Queue buttons. Accept sends CMSG_LFG_SET_ROLES with the
selected role mask. Previously only showed passive "Role check in progress"
text with no way to respond.

Subject: [PATCH 087/435] feat: add /reload command to re-initialize addon
 system

Add AddonManager::reload() which saves all SavedVariables, shuts down the
Lua VM, re-initializes it, rescans .toc files, and reloads all addons.
Wire /reload, /reloadui, /rl slash commands that call reload() and fire
VARIABLES_LOADED + PLAYER_LOGIN + PLAYER_ENTERING_WORLD lifecycle events.
Essential for addon development and troubleshooting.

Subject: [PATCH 088/435] feat: show enchant name and XP source creature in
 chat messages

SMSG_ENCHANTMENTLOG now resolves spell name and shows "You enchant with
[name]" or "[Caster] enchants your item with [name]" instead of silent
debug log. SMSG_LOG_XPGAIN now shows creature name: "Wolf dies, you gain
45 experience" instead of generic "You gain 45 experience" for kill XP.

Subject: [PATCH 090/435] feat: add sun height attenuation and warm sunset tint
 to lens flare
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Reduce flare intensity when sun is near the horizon via smoothstep on
sunDir.z (0→0.25 range). Apply amber/orange color shift to flare elements
at sunrise/sunset for a warm golden glow. Prevents overly bright flares
at low sun angles while enhancing atmospheric mood.

Subject: [PATCH 092/435] feat: add generic UnitAura(unit, index, filter) Lua
 API function

Add UnitAura() that accepts WoW-compatible filter strings: "HELPFUL" for
buffs, "HARMFUL" for debuffs. Delegates to existing UnitBuff/UnitDebuff
logic. Many addons (WeakAuras, Grid, etc.) use UnitAura with filter
strings rather than separate UnitBuff/UnitDebuff calls.

Subject: [PATCH 093/435] fix: sync cloud density with weather intensity and
 DBC cloud coverage

Cloud renderer's density was hardcoded at 0.35 and never updated from the
DBC-driven cloudDensity parameter. Now setDensity() is called each frame
with the lighting manager's cloud coverage value. Active weather (rain/
snow/storm) additionally boosts cloud density by up to 0.4 so clouds
visibly thicken during storms.

 on entity destroy

When SMSG_DESTROY_OBJECT removes an entity, now also purge combat text
entries targeting that GUID (prevents floating damage numbers on despawned
mobs), erase unit cast state (prevents stale cast bars), and clear cached
auras (prevents stale buff/debuff data for destroyed units).

Subject: [PATCH 101/435] fix: increase world packet size limit from 16KB to
 32KB

The 0x4000 (16384) limit was too conservative and could disconnect the
client when the server sends large packets such as SMSG_GUILD_ROSTER
with 500+ members (~30KB) or SMSG_AUCTION_LIST with many results.
Increase to 0x8000 (32768) which covers all normal gameplay while still
protecting against framing desync from encryption errors.

Subject: [PATCH 105/435] fix: compute aura expirationTime for addon countdown
 timers

The expirationTime field (7th return value of UnitBuff/UnitDebuff/UnitAura)
was hardcoded to 0. Now returns GetTime() + remaining seconds, matching
WoW's convention where addons compute remaining = expirationTime - GetTime().
Enables buff/debuff timer addons like OmniCC and WeakAuras.

Subject: [PATCH 106/435] fix: invoke despawn callbacks during zone transitions
 to release renderer resources

handleNewWorld() previously called entityManager.clear() directly without
notifying the renderer, leaving stale M2 instances and character models
allocated. Now iterates all entities and fires creatureDespawnCallback,
playerDespawnCallback, and gameObjectDespawnCallback before clearing.
Also clears player caches (visible items, cast states, aura cache,
combat text) to prevent state leaking between zones.

Subject: [PATCH 110/435] feat: play minimap ping sound when party members ping
 the map

Add playMinimapPing() to UiSoundManager with MapPing.wav (falls back to
target select sound). Play the ping sound in MSG_MINIMAP_PING handler
when the sender is not the local player. Provides audio feedback for
party member map pings, matching WoW behavior.

Cap gossipPois_ at 200 entries (both gossip POI and quest POI paths) to

240 FPS frame rate limiter when vsync is off to prevent 100% CPU usage —
sleeps for remaining frame budget when frame completes in under 4ms.

Subject: [PATCH 116/435] fix: return WoW-standard (start, duration, enabled)
 from GetSpellCooldown

Previously returned (0, remaining) which broke addons computing remaining
time as start + duration - GetTime(). Now returns (GetTime(), remaining, 1)
when on cooldown and (0, 0, 1) when off cooldown, plus the third 'enabled'
value that WoW always returns. Fixes cooldown display in OmniCC and similar.

Subject: [PATCH 117/435] feat: resolve random property/suffix names for item
 display

Load ItemRandomProperties.dbc and ItemRandomSuffix.dbc lazily to resolve
suffix names like "of the Eagle", "of the Monkey" etc. Add
getRandomPropertyName(id) callback on GameHandler wired through Application.
Append suffix to item names in SMSG_ITEM_PUSH_RESULT loot notifications
so items display as "Leggings of the Eagle" instead of just "Leggings".

Subject: [PATCH 118/435] feat: show random suffix names in loot roll popup and
 roll-won messages

Apply getRandomPropertyName() to SMSG_LOOT_START_ROLL and SMSG_LOOT_ROLL_WON
handlers so items with random suffixes display correctly in group loot
contexts (e.g., "Leggings of the Eagle" in the Need/Greed popup and
"Player wins Leggings of the Eagle (Need 85)" in chat).

Subject: [PATCH 138/435] feat: add targettarget, focustarget, pettarget,
 mouseovertarget unit IDs

Support compound unit IDs that resolve an entity's current target via
UNIT_FIELD_TARGET_LO/HI update fields. This enables addons to query
target-of-target info (e.g., UnitName("targettarget"), UnitHealth("focustarget"))
which is essential for threat meters and unit frame addons.

Subject: [PATCH 139/435] feat: add loot window Lua API for addon compatibility

Implement 6 loot-related WoW Lua API functions:
- GetNumLootItems() returns count of items in loot window
- GetLootSlotInfo(slot) returns texture, name, quantity, quality, locked
- GetLootSlotLink(slot) returns item link string
- LootSlot(slot) takes an item from loot
- CloseLoot() closes the loot window
- GetLootMethod() returns current group loot method

These pair with the LOOT_OPENED/LOOT_CLOSED events to enable loot
addons (AutoLoot, loot filters, master loot helpers).

Subject: [PATCH 140/435] feat: add GetCursorPosition, screen size queries, and
 frame positioning methods
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add global Lua API functions:
- GetCursorPosition() returns mouse x,y screen coordinates
- GetScreenWidth()/GetScreenHeight() return window dimensions

Add frame methods for UI layout:
- SetPoint, SetSize, SetWidth, SetHeight, GetWidth, GetHeight, GetCenter
- SetAlpha, GetAlpha, SetParent, GetParent

These enable UI customization addons to query cursor position, screen
dimensions, and manage frame layout — fundamental for unit frames,
action bars, and tooltip addons.

Subject: [PATCH 141/435] fix: remove Lua stubs overriding C implementations;
 add GameTooltip and frame factories
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Fix GetScreenWidth/GetScreenHeight/GetNumLootItems/GetFramerate being
overridden by hardcoded Lua stubs that ran after the C functions were
registered. Now the real C implementations correctly take effect.

Add GameTooltip global frame with 20+ methods (SetOwner, ClearLines,
AddLine, AddDoubleLine, SetText, NumLines, GetText, SetHyperlink, etc.)
and ShoppingTooltip1/2 — critical for virtually all WoW addons.

Add frame:CreateTexture() and frame:CreateFontString() methods returning
stub objects with common API methods, enabling UI creation addons.

Add real GetFramerate() returning actual FPS from ImGui.

Subject: [PATCH 142/435] feat: fire UNIT_HEALTH/POWER/AURA events for party
 members; fix closeLoot event
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Fire UNIT_HEALTH, UNIT_POWER, and UNIT_AURA events from
SMSG_PARTY_MEMBER_STATS with proper unit IDs (party1..4, raid1..40).
Previously, health/power changes for party members via the stats packet
were silent — raid frame addons never got notified.

Also fix closeLoot() not firing LOOT_CLOSED event when the loot window
is closed by the player (only handleLootReleaseResponse fired it).

Implement 8 targeting functions commonly used by unit frame addons,

- TargetUnit(unitId) / ClearTarget()
- FocusUnit(unitId) / ClearFocus()
- AssistUnit(unitId) — target the given unit's target
- TargetLastTarget() — return to previous target
- TargetNearestEnemy() / TargetNearestFriend() — tab-targeting

Subject: [PATCH 144/435] feat: add UseAction, CancelUnitBuff, and
 CastSpellByID Lua functions

Implement 3 critical gameplay Lua API functions:
- UseAction(slot) activates an action bar slot (spell/item), enabling
  action bar addons like Bartender/Dominos to fire abilities
- CancelUnitBuff("player", index) cancels a buff by index, enabling
  auto-cancel and buff management addons
- CastSpellByID(id) casts a spell by numeric ID, enabling macro addons
  and spell queuing systems

Subject: [PATCH 145/435] feat: fire UNIT_SPELLCAST_SENT and
 UNIT_SPELLCAST_STOP events

Fire UNIT_SPELLCAST_SENT when the player initiates a spell cast (before
server confirms), enabling cast bar addons like Quartz to show latency.
Includes target name and spell ID as arguments.

Fire UNIT_SPELLCAST_STOP whenever a cast bar should disappear:
- On successful cast completion (SMSG_SPELL_GO)
- On cast failure (SMSG_CAST_RESULT with error)
- On spell interrupt (SMSG_SPELL_FAILURE/SMSG_SPELL_FAILED_OTHER)
- On manual cast cancel

These events are essential for cast bar replacement addons to properly
track when casts begin and end.

Subject: [PATCH 146/435] feat: add LibStub and CallbackHandler-1.0 for Ace3
 addon compatibility
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Implement LibStub — the universal library version management system that
virtually every WoW addon framework depends on (Ace3, LibDataBroker,
LibSharedMedia, etc.). Without LibStub, most popular addons fail to load.

Also implement CallbackHandler-1.0 — the standard event callback library
used by Ace3-based addons for inter-module communication. Supports
RegisterCallback, UnregisterCallback, UnregisterAllCallbacks, and Fire.

These two libraries unlock the entire Ace3 addon ecosystem.

Subject: [PATCH 147/435] feat: add GetNumSkillLines and GetSkillLineInfo for
 profession addons

Implement skill line API functions that profession and tradeskill addons
need to display player skills:
- GetNumSkillLines() returns count of player skills
- GetSkillLineInfo(index) returns full 12-value tuple: name, isHeader,
  isExpanded, rank, tempPoints, modifier, maxRank, isAbandonable, etc.

Data comes from SMSG_SKILLS_INFO update fields and SkillLine.dbc names.

Subject: [PATCH 148/435] feat: add talent tree Lua API for talent inspection
 addons

Implement 5 talent-related WoW Lua API functions:
- GetNumTalentTabs() returns class-specific talent tree count (usually 3)
- GetTalentTabInfo(tab) returns name, icon, pointsSpent, background
- GetNumTalents(tab) returns talent count in a specific tree
- GetTalentInfo(tab, index) returns full 8-value tuple with name, tier,
  column, current rank, max rank, and availability
- GetActiveTalentGroup() returns active spec (1 or 2)

Data sourced from Talent.dbc, TalentTab.dbc, and the server-sent talent
info packet. Enables talent addons and spec display addons.

Subject: [PATCH 149/435] feat: fire UNIT_HEALTH/UNIT_POWER events from
 dedicated update packets

SMSG_HEALTH_UPDATE and SMSG_POWER_UPDATE are high-frequency WotLK
packets that update entity health/power values but weren't firing
addon events. Unit frame addons (Pitbull, oUF, SUF) depend on these
events to update health/mana bars in real-time.

Now fire UNIT_HEALTH for player/target/focus on SMSG_HEALTH_UPDATE
and UNIT_POWER on SMSG_POWER_UPDATE, matching the events already
fired from the UPDATE_OBJECT path.

Subject: [PATCH 150/435] fix: fire talent/spell events correctly when learning
 talents

Fix bug where learning a talent caused an early return before firing
LEARNED_SPELL_IN_TAB and SPELLS_CHANGED events, leaving talent addons
unaware of changes. Now talent learning fires CHARACTER_POINTS_CHANGED,
PLAYER_TALENT_UPDATE, LEARNED_SPELL_IN_TAB, and SPELLS_CHANGED.

Also fire CHARACTER_POINTS_CHANGED, ACTIVE_TALENT_GROUP_CHANGED, and
PLAYER_TALENT_UPDATE from handleTalentsInfo (SMSG_TALENTS_INFO), so
talent addons update when the full talent state is received from the
server (login, spec switch, respec).

Also fire UNIT_HEALTH/UNIT_POWER events from SMSG_HEALTH_UPDATE and
SMSG_POWER_UPDATE packets for real-time unit frame updates.

Subject: [PATCH 152/435] feat: add UIDropDownMenu framework, font objects, and
 UI global stubs

Add the UIDropDownMenu compatibility framework used by virtually every
addon with settings or selection menus: UIDropDownMenu_Initialize,
CreateInfo, AddButton, SetWidth, SetText, GetText, SetSelectedID, etc.

Add global font object stubs (GameFontNormal, GameFontHighlight, etc.)
referenced by CreateFontString template arguments.

Add UISpecialFrames table, InterfaceOptionsFrame for addon panels,
InterfaceOptions_AddCategory, and common font color constants
(GRAY_FONT_COLOR, NORMAL_FONT_COLOR, etc.).

These globals prevent nil-reference errors in most popular addons.

Subject: [PATCH 153/435] feat: add WoW table/string/math/bit utility functions
 for addon compat

Add commonly used WoW global utility functions that many addons depend on:

Table: tContains, tInvert, CopyTable, tDeleteItem
String: strupper, strlower, strfind, strsub, strlen, strrep, strbyte,
  strchar, strrev, gsub, gmatch, strjoin
Math: Clamp, Round
Bit ops: bit.band, bit.bor, bit.bxor, bit.bnot, bit.lshift, bit.rshift
  (pure Lua implementation for Lua 5.1 which lacks native bit ops)

These prevent nil-reference errors and missing-function crashes in
addons that use standard WoW utility globals.

Subject: [PATCH 154/435] feat: add 40+ frame metatable methods to prevent
 addon nil-reference errors

Add commonly called frame methods as no-ops or with basic state tracking
on the frame metatable, so any CreateFrame result supports them:

Layout: SetFrameLevel/Get, SetFrameStrata/Get, SetScale/Get/GetEffective,
  ClearAllPoints, SetID/GetID, GetLeft/Right/Top/Bottom, GetNumPoints,
  GetPoint, SetHitRectInsets
Behavior: EnableMouse, EnableMouseWheel, SetMovable, SetResizable,
  RegisterForDrag, SetClampedToScreen, SetToplevel, Raise, Lower,
  StartMoving, StopMovingOrSizing, RegisterForClicks, IsMouseOver
Visual: SetBackdrop, SetBackdropColor, SetBackdropBorderColor
Scripting: HookScript (chains with existing SetScript handlers),
  SetAttribute/GetAttribute, GetObjectType
Sizing: SetMinResize, SetMaxResize

These prevent the most common addon errors when addons call standard
WoW frame methods on CreateFrame results.

Subject: [PATCH 155/435] feat: support SavedVariablesPerCharacter for
 per-character addon data

Implement the SavedVariablesPerCharacter TOC directive that many addons
use to store different settings per character (Bartender, Dominos,
MoveAnything, WeakAuras, etc.). Without this, all characters share the
same addon data file.

Per-character files are stored as <AddonName>.<CharacterName>.lua.saved
alongside the existing account-wide <AddonName>.lua.saved files. The
character name is resolved from the player GUID at world entry time.

Changes:
- TocFile::getSavedVariablesPerCharacter() parses the TOC directive
- AddonManager loads/saves per-character vars alongside account-wide vars
- Character name set from game handler before addon loading

 ItemDisplayInfo.dbc for Lua API
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add ItemIconPathResolver that lazily loads ItemDisplayInfo.dbc to map
displayInfoId → icon texture path. This fixes three Lua API functions
that previously returned nil for item icons:

- GetItemInfo() field 10 (texture) now returns the icon path
- GetActionTexture() for item-type action bar slots now returns icons
- GetLootSlotInfo() field 1 (texture) now returns proper item icons
  instead of incorrectly using the spell icon resolver

Follows the same lazy-loading pattern as SpellIconPathResolver. The DBC
is loaded once on first query and cached for all subsequent lookups.

Subject: [PATCH 157/435] feat: fire events for loot rolls, trade windows, and
 duels

Add missing addon events for three gameplay systems:

Loot rolls:
- START_LOOT_ROLL fires on SMSG_LOOT_START_ROLL with slot and countdown
- LOOT_SLOT_CLEARED fires when a loot item is removed (SMSG_LOOT_REMOVED)

Trade:
- TRADE_REQUEST when another player initiates a trade
- TRADE_SHOW when the trade window opens
- TRADE_CLOSED when trade is cancelled, declined, or completed
- TRADE_ACCEPT_UPDATE when the trade partner accepts

Duels:
- DUEL_REQUESTED with challenger name on incoming duel challenge
- DUEL_FINISHED when a duel completes or is cancelled

Subject: [PATCH 162/435] feat: apply M2 color alpha and transparency tracks to
 batch opacity
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Apply at-rest values from M2 color alpha and transparency animation
tracks to batch rendering opacity. This fixes models that should render
as semi-transparent (ghosts, ethereal effects, fading doodads) but were
previously rendering at full opacity.

The fix multiplies colorAlphas[batch.colorIndex] and
textureWeights[batch.transparencyIndex] into batchOpacity during model
setup. Zero values are skipped to avoid the edge case where animated
tracks start at 0 (invisible) and animate up — baking that first
keyframe would make the entire batch permanently invisible.

Subject: [PATCH 163/435] fix: add mail, auction, quest, and trade windows to
 Escape key chain

The Escape key now properly closes these windows before showing the
escape menu:
- Mail window (closeMailbox)
- Auction house (closeAuctionHouse)
- Quest details dialog (declineQuest)
- Quest offer reward dialog (closeQuestOfferReward)
- Quest request items dialog (closeQuestRequestItems)
- Trade window (cancelTrade)

Previously these windows required clicking their close button since
Escape would skip directly to the escape menu.

Subject: [PATCH 165/435] feat: add SendAddonMessage and
 RegisterAddonMessagePrefix for addon comms

Implement the addon messaging API used by virtually every multiplayer
addon (DBM, BigWigs, EPGP, RC Loot Council, WeakAuras, etc.):

- SendAddonMessage(prefix, text, chatType, target) sends an addon
  message encoded as "prefix\ttext" via the appropriate chat channel
- RegisterAddonMessagePrefix(prefix) registers a prefix for filtering
  incoming addon messages
- IsAddonMessagePrefixRegistered(prefix) checks registration status
- C_ChatInfo table with aliases for the above functions (newer API compat)

Without these functions, all inter-addon communication between players
fails, breaking boss mods, loot distribution, and group coordination.

Subject: [PATCH 166/435] feat: add guild roster Lua API for guild management
 addons

Implement 5 guild-related WoW Lua API functions:
- IsInGuild() returns whether the player is in a guild
- GetGuildInfo("player") returns guildName, rankName, rankIndex
- GetNumGuildMembers() returns totalMembers, onlineMembers
- GetGuildRosterInfo(index) returns full 11-value tuple: name, rank,
  rankIndex, level, class, zone, note, officerNote, online, status, classId
- GetGuildRosterMOTD() returns the guild message of the day

Data sourced from SMSG_GUILD_ROSTER and SMSG_GUILD_QUERY_RESPONSE.
Enables guild management addons (GreenWall, officer tools, roster UIs).

Subject: [PATCH 167/435] fix: handle NPC facing-only rotation in
 SMSG_MONSTER_MOVE

Fix bug where NPCs receiving moveType=4 (FacingAngle) or moveType=3
(FacingTarget) monster move packets with zero waypoints would not
rotate in place. The handler only processed orientation when hasDest
was true, but facing-only updates have no destination waypoints.

Now NPCs properly rotate when:
- moveType=4: server specifies an exact facing angle (e.g., NPC turns
  to face the player during dialogue or scripted events)
- moveType=3: NPC should face a specific target entity

This fixes NPCs appearing frozen/unresponsive during scripted events,
quest interactions, and patrol waypoint facing changes.

Subject: [PATCH 168/435] feat: add player name tab-completion in chat input

When typing commands like /w, /whisper, /invite, /trade, /duel, /follow,
/inspect, etc., pressing Tab now cycles through matching player names.

Name sources (in priority order):
1. Last whisper sender (most likely target for /r follow-ups)
2. Party/raid members
3. Friends list
4. Nearby visible players

Tab cycles through all matches; single match auto-appends a space.
Complements the existing slash-command tab-completion.

Subject: [PATCH 169/435] fix: UnitClass and UnitRace now work for target,
 focus, party, and all units
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Previously UnitClass() only returned the correct class for "player" and
returned "Unknown" for all other units (target, focus, party1-4, etc.).
UnitRace() had the same bug.

Now both functions read UNIT_FIELD_BYTES_0 from the entity's update
fields to resolve class (byte 1) and race (byte 0) for any unit. This
fixes unit frame addons, class-colored names, and race-based logic for
all unit IDs.

Also fix UnitRace to return 3 values (localized, English, raceId) to
match WoW's API signature — previously it only returned 1.

Subject: [PATCH 170/435] feat: add unit state query functions and fix
 UnitAffectingCombat

Add 6 commonly needed unit state functions:
- UnitIsGhost(unit) checks ghost flag from UNIT_FIELD_FLAGS
- UnitIsDeadOrGhost(unit) combines dead + ghost checks
- UnitIsAFK(unit) / UnitIsDND(unit) check player flags
- UnitPlayerControlled(unit) true for players and player pets
- UnitSex(unit) reads gender from UNIT_FIELD_BYTES_0 byte 2

Fix UnitAffectingCombat to check UNIT_FLAG_IN_COMBAT (0x00080000)
from entity update fields for any unit, not just "player". Previously
returned false for all non-player units.

These functions are needed by unit frame addons (SUF, Pitbull, oUF)
to properly display ghost state, AFK/DND status, and combat state.

Subject: [PATCH 171/435] fix: unit API functions return data for out-of-range
 party members

Previously UnitHealth, UnitHealthMax, UnitPower, UnitPowerMax, UnitLevel,
UnitName, and UnitExists returned 0/"Unknown"/false for party members in
other zones because the entity doesn't exist in the entity manager.

Now these functions fall back to SMSG_PARTY_MEMBER_STATS data stored in
GroupMember structs, which provides health, power, level, and name for
all party members regardless of distance. UnitName also falls back to
the player name cache.

This fixes raid frame addons (Grid, Healbot, VuhDo) showing blank/zero
data for party members who are out of UPDATE_OBJECT range.

Subject: [PATCH 172/435] feat: cache player class/race from name queries for
 UnitClass/UnitRace
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add playerClassRaceCache_ that stores classId and raceId from
SMSG_NAME_QUERY_RESPONSE. This enables UnitClass and UnitRace to return
correct data for players who were previously seen but are now out of
UPDATE_OBJECT range.

Fallback chain for UnitClass/UnitRace is now:
1. Entity update fields (UNIT_FIELD_BYTES_0) — for nearby entities
2. Name query cache — for previously queried players
3. getPlayerClass/Race() — for the local player

This improves class-colored names in chat, unit frames, and nameplates
for players who move out of view range.

Subject: [PATCH 173/435] feat: resolve spell cast time and range from DBC for
 GetSpellInfo
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add SpellDataResolver that lazily loads Spell.dbc, SpellCastTimes.dbc,
and SpellRange.dbc to provide cast time and range data. GetSpellInfo()
now returns real castTime (ms), minRange, and maxRange instead of
hardcoded 0 values.

This enables spell tooltip addons, cast bar addons (Quartz), and range
check addons to display accurate spell information. The DBC chain is:
  Spell.dbc[CastingTimeIndex] → SpellCastTimes.dbc[Base ms]
  Spell.dbc[RangeIndex] → SpellRange.dbc[MinRange, MaxRange]

Follows the same lazy-loading pattern as SpellIconPathResolver and
ItemIconPathResolver.

Subject: [PATCH 174/435] feat: add spell power cost to SpellDataResolver; fix
 IsUsableSpell mana check

Extend SpellDataInfo with manaCost and powerType fields, extracted from
Spell.dbc ManaCost and PowerType columns. This enables IsUsableSpell()
to properly check if the player has enough mana/rage/energy to cast.

Previously IsUsableSpell always returned notEnoughMana=false since cost
data wasn't available. Now it compares the spell's DBC mana cost against
the player's current power, returning accurate usability and mana state.

This fixes action bar addons showing abilities as usable when the player
lacks sufficient power, and enables OmniCC-style cooldown text to
properly dim insufficient-power abilities.

Subject: [PATCH 175/435] fix: IsUsableAction now checks spell power cost from
 DBC

IsUsableAction previously always returned notEnoughMana=false. Now it
checks the spell's mana cost from SpellDataResolver against the player's
current power, matching the same fix applied to IsUsableSpell.

This fixes action bar addons (Bartender, Dominos) incorrectly showing
abilities as usable when the player lacks mana/rage/energy.

Subject: [PATCH 176/435] feat: add ACHIEVEMENT_EARNED event and 15 missing
 CHAT_MSG_* events
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Fire ACHIEVEMENT_EARNED event when a player earns an achievement,
enabling achievement tracking addons.

Add 15 previously unmapped chat type → addon event mappings:
- CHAT_MSG_ACHIEVEMENT, CHAT_MSG_GUILD_ACHIEVEMENT
- CHAT_MSG_WHISPER_INFORM (echo of sent whispers)
- CHAT_MSG_RAID_LEADER, CHAT_MSG_BATTLEGROUND_LEADER
- CHAT_MSG_MONSTER_SAY/YELL/EMOTE/WHISPER
- CHAT_MSG_RAID_BOSS_EMOTE/WHISPER
- CHAT_MSG_BG_SYSTEM_NEUTRAL/ALLIANCE/HORDE

These events are needed by boss mod addons (DBM, BigWigs) to detect
boss emotes, by achievement trackers, and by chat filter addons that
process all message types.

Subject: [PATCH 177/435] feat: fire READY_CHECK, READY_CHECK_CONFIRM,
 READY_CHECK_FINISHED events

Fire addon events for the raid ready check system:
- READY_CHECK fires when a ready check is initiated, with initiator name
- READY_CHECK_CONFIRM fires for each player's response, with GUID and
  ready state (1=ready, 0=not ready)
- READY_CHECK_FINISHED fires when the ready check period ends

These events are used by raid frame addons (Grid, VuhDo, Healbot) to
show ready check status on unit frames, and by raid management addons
to track responsiveness.

Subject: [PATCH 178/435] feat: add RAID_TARGET_UPDATE event and
 GetRaidTargetIndex/SetRaidTarget

Fire RAID_TARGET_UPDATE event when raid markers (skull, cross, etc.)
are set or cleared on targets. Add two Lua API functions:
- GetRaidTargetIndex(unit) returns marker index 1-8 (or nil)
- SetRaidTarget(unit, index) sets marker 1-8 (or 0 to clear)

Enables raid marking addons and nameplate addons that display raid
icons to react to marker changes in real-time.

Subject: [PATCH 179/435] feat: add action bar constants and functions for
 Bartender/Dominos compat

Add essential WoW action bar globals and functions that action bar
addons (Bartender4, Dominos, CT_BarMod) require on initialization:

Constants: NUM_ACTIONBAR_BUTTONS, NUM_ACTIONBAR_PAGES, NUM_PET_ACTION_SLOTS
Functions: GetActionBarPage, ChangeActionBarPage, GetBonusBarOffset,
  GetActionText, GetActionCount
Binding: GetBindingKey, GetBindingAction, SetBinding, SaveBindings
Macro: GetNumMacros, GetMacroInfo, GetMacroBody, GetMacroIndexByName
Stance: GetNumShapeshiftForms, GetShapeshiftFormInfo
Pet: GetPetActionInfo, GetPetActionsUsable

These prevent nil-reference errors during addon initialization and
enable basic action bar addon functionality.

Subject: [PATCH 180/435] feat: fire INSPECT_READY event from both WotLK and
 Classic inspect paths

Fire INSPECT_READY with the inspected player's GUID when inspection
results are received. Fires from both:
- WotLK SMSG_TALENTS_INFO type=1 (talent + gear inspect)
- Classic SMSG_INSPECT (gear-only inspect)

Used by GearScore, TacoTip, and other inspection addons that need
to know when inspect data is available for a specific player.

Subject: [PATCH 183/435] feat: add GetAddOnMetadata for reading TOC directives
 from Lua

Implement GetAddOnMetadata(addonNameOrIndex, key) which reads arbitrary
TOC file directives. All directives are now stored in the addon info
registry table under a "metadata" sub-table.

This enables addons to read their own version, author, X-* custom
fields, and other TOC metadata at runtime. Used by addon managers,
version checkers, and self-updating addons.

Subject: [PATCH 185/435] fix: fire UNIT_SPELLCAST_FAILED/STOP for other units
 on SPELL_FAILED_OTHER

SMSG_SPELL_FAILED_OTHER was clearing the unit cast state but not firing
addon events. Cast bar addons (Quartz, ClassicCastbars) showing target/
focus cast bars need UNIT_SPELLCAST_FAILED and UNIT_SPELLCAST_STOP to
clear the bar when another unit's cast fails.

Now fires both events for target and focus units, matching the behavior
already implemented for the player's own cast failures.

Subject: [PATCH 189/435] feat: fire PLAYER_CONTROL_LOST/GAINED on movement
 control changes

Fire PLAYER_CONTROL_LOST when SMSG_CLIENT_CONTROL_UPDATE revokes player

Subject: [PATCH 191/435] feat: display Lua addon errors as in-game UI errors

Previously Lua addon errors only logged to the log file. Now they
display as red UI error text to the player (same as spell errors and
game warnings), helping addon developers debug issues in real-time.

Add LuaErrorCallback to LuaEngine, fire it from event handler and
frame OnEvent pcall error paths. Wire the callback to GameHandler's
addUIError in application.cpp.

Subject: [PATCH 193/435] fix: display Lua errors from OnUpdate, executeFile,
 executeString as UI errors

Extend the Lua error UI display to cover all error paths:
- OnUpdate frame callbacks (previously only logged)
- executeFile loading errors (now also shown as UI error)
- executeString /run errors (now also shown as UI error)

This ensures addon developers see ALL Lua errors in-game, not just
event handler errors from the previous commit.

Subject: [PATCH 194/435] fix: include pet unit ID in all spellcast addon
 events

Add pet GUID check to all spellcast event dispatchers:
- UNIT_SPELLCAST_START
- UNIT_SPELLCAST_SUCCEEDED
- UNIT_SPELLCAST_CHANNEL_START
- UNIT_SPELLCAST_CHANNEL_STOP
- UNIT_SPELLCAST_INTERRUPTED + STOP

Previously these events only fired for player/target/focus, meaning
pet cast bars and pet spell tracking addons wouldn't work. Now pet
spellcasts properly fire with unitId="pet".

Subject: [PATCH 210/435] feat: add common WoW global constants for addon
 compatibility

Add frequently referenced WoW global constants that many addons check:
- MAX_TALENT_TABS, MAX_NUM_TALENTS
- BOOKTYPE_SPELL, BOOKTYPE_PET
- MAX_PARTY_MEMBERS, MAX_RAID_MEMBERS, MAX_ARENA_TEAMS
- INVSLOT_FIRST_EQUIPPED, INVSLOT_LAST_EQUIPPED
- NUM_BAG_SLOTS, NUM_BANKBAGSLOTS, CONTAINER_BAG_OFFSET
- MAX_SKILLLINE_TABS, TRADE_ENCHANT_SLOT

Prevents nil-reference errors when addons use these standard constants.

Subject: [PATCH 215/435] feat: show grey nameplates for mobs tapped by other
 players

Check UNIT_DYNFLAG_TAPPED_BY_PLAYER (0x0004) on hostile NPC nameplates.
Mobs tagged by another player now show grey health bars instead of red,
matching WoW's visual indication that the mob won't yield loot/XP.

Mobs with TAPPED_BY_ALL_THREAT_LIST (0x0008) still show red since
those are shared-tag mobs that give loot to everyone.

Subject: [PATCH 219/435] feat: add UnitThreatSituation for threat meter and
 tank addons

Implement UnitThreatSituation(unit, mobUnit) returning 0-3 threat level:
- 0: not on threat table
- 1: in combat but not tanking (mob targeting someone else)
- 3: securely tanking (mob is targeting this unit)

Approximated from mob's UNIT_FIELD_TARGET to determine who the mob is
attacking. Used by threat meter addons (Omen, ThreatPlates) and tank
UI addons to display threat state.

Implement UnitDetailedThreatSituation(unit, mobUnit) returning:

Used by Omen and other threat meter addons that query detailed threat
info per mob-target pair.

Fire UNIT_THREAT_LIST_UPDATE from SMSG_THREAT_UPDATE,

already parsed and stored in threatLists_ — this event notifies
addon systems when the data changes.

their displays when threat values update.

Subject: [PATCH 238/435] feat: add UnitIsVisible for entity visibility checks

Returns true when the unit's entity exists in the entity manager
(within UPDATE_OBJECT range). Unlike UnitExists which falls back to
party member data, UnitIsVisible only returns true for entities that
can actually be rendered on screen.

Used by nameplate addons and proximity addons to check if a unit is
within visual range.

Subject: [PATCH 242/435] fix: use geoset 503 for bare shins to reduce knee
 width discontinuity

Change the bare shin (no boots) default from geoset 502 to 503 across
all four code paths (character creation, character preview, equipment
update, NPC rendering).

Geoset 503 has Y width ~0.44 which better matches the thigh mesh
width (~0.42) than 502's width (~0.39), reducing the visible gap at
the knee joint where lower and upper leg meshes meet.

in an instance and releases to an outdoor graveyard.

Previously the corpse position was only set from the entity death
location, which could be wrong for cross-map ghost runs.

Subject: [PATCH 244/435] fix: query corpse position on ghost login for
 accurate minimap marker

When logging in while already dead (reconnect/crash recovery), send
MSG_CORPSE_QUERY to get the server-authoritative corpse location.
Without this, the minimap corpse marker would be missing or point to
the wrong position after reconnecting as a ghost.

Subject: [PATCH 249/435] feat: add UnitCastingInfo/UnitChannelInfo Lua API and
 fix SMSG_CAST_FAILED events
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Expose cast/channel state to Lua addons via UnitCastingInfo(unit) and
UnitChannelInfo(unit), matching the WoW API signature (name, text, texture,
startTime, endTime, isTradeSkill, castID, notInterruptible). Works for
player, target, focus, and pet units using existing UnitCastState tracking.

Also fix handleCastFailed (SMSG_CAST_FAILED, Classic/TBC path) to fire
UNIT_SPELLCAST_FAILED and UNIT_SPELLCAST_STOP events — previously only
the WotLK SMSG_CAST_RESULT path fired these, leaving Classic/TBC addons
unaware of cast failures.

Adds isChannel field to UnitCastState and getCastTimeTotal() accessor.

Subject: [PATCH 250/435] feat: add IsActionInRange, GetActionInfo, and
 GetActionCount Lua API

IsActionInRange(slot) checks if the spell on an action bar slot is within
range of the current target, using DBC spell range data and entity positions.
Returns 1/0/nil matching the WoW API contract.

GetActionInfo(slot) returns action type ("spell"/"item"/"macro"), id, and
subType for action bar interrogation by bar addons.

GetActionCount(slot) returns item stack count across backpack and bags for
consumable tracking on action bars.

Subject: [PATCH 251/435] fix: restore correct CharSections.dbc field indices
 for character textures
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

PR #19 (572bb4ef) swapped CharSections.dbc field indices, placing
Texture1-3 at fields 4-6 and VariationIndex/ColorIndex at 8-9. Binary
analysis of the actual DBC files (Classic, TBC, Turtle — all identical
layout, no WotLK-specific override) confirms the correct order is:

  Field 4 = VariationIndex
  Field 5 = ColorIndex
  Field 6 = Texture1 (string)
  Field 7 = Texture2 (string)
  Field 8 = Texture3 (string)
  Field 9 = Flags

With the wrong indices, VariationIndex/ColorIndex reads returned string
offsets (garbage values that never matched), so all CharSections lookups
failed silently — producing white untextured character models at the
login screen and in-world.

Fixes all 4 expansion JSON layouts, hardcoded fallbacks in
character_preview.cpp, application.cpp, and character_create_screen.cpp.
Also handles the single-layer edge case (body skin only, no face/underwear)
by loading the texture directly instead of skipping compositing.

Subject: [PATCH 252/435] feat: add UnitStat and combat chance Lua API for
 character sheet addons
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Expose server-authoritative player stats to Lua addons:

- UnitStat(unit, statIndex) — returns STR/AGI/STA/INT/SPI (base,
  effective, posBuff, negBuff) matching the WoW API 4-return signature
- GetDodgeChance, GetParryChance, GetBlockChance — defensive stats
- GetCritChance, GetRangedCritChance — physical crit percentages
- GetSpellCritChance(school) — per-school spell crit
- GetCombatRating(index) — WotLK combat rating system
- GetSpellBonusDamage, GetSpellBonusHealing — caster stat display
- GetAttackPowerForStat, GetRangedAttackPower — melee/ranged AP

All data is already tracked from SMSG_UPDATE_OBJECT field updates;
these functions simply expose existing GameHandler getters to Lua.
Enables PaperDollFrame, DejaCharacterStats, and similar addons.

Subject: [PATCH 253/435] feat: add GetInventorySlotInfo for PaperDollFrame and
 BankFrame

Maps WoW equipment slot names (e.g. "HeadSlot", "MainHandSlot") to
inventory slot IDs, empty-slot textures, and relic check flags.
Supports case-insensitive matching with optional "Slot" suffix stripping.

Unblocks PaperDollFrame.lua and BankFrame.lua which call this function
to resolve slot button IDs during UI initialization.

Subject: [PATCH 254/435] feat: add quest watch/tracking and selection Lua API
 for WatchFrame
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Implement the quest tracking functions needed by WatchFrame.lua:
- SelectQuestLogEntry/GetQuestLogSelection — quest log selection state
- GetNumQuestWatches — count of tracked quests
- GetQuestIndexForWatch(watchIdx) — map Nth watched quest to log index
- AddQuestWatch/RemoveQuestWatch — toggle quest tracking by log index
- IsQuestWatched — check if a quest log entry is tracked
- GetQuestLink — generate colored quest link string

Backed by existing trackedQuestIds_ set and questLog_ vector.
Adds selectedQuestLogIndex_ state to GameHandler for quest selection.

Subject: [PATCH 255/435] feat: add spell book tab API for SpellBookFrame addon
 compatibility
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Implement GetNumSpellTabs, GetSpellTabInfo, GetSpellBookItemInfo, and
GetSpellBookItemName — the core functions SpellBookFrame.lua needs to
organize known spells into class skill line tabs.

Tabs are built lazily from knownSpells grouped by SkillLineAbility.dbc
mappings (category 7 = class). A "General" tab collects spells not in
any class skill line. Tabs auto-rebuild when the spell count changes.

Also adds SpellBookTab struct and getSpellBookTabs() to GameHandler.

Subject: [PATCH 256/435] feat: fire PLAYER_ENTERING_WORLD and critical login
 events for addons
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

PLAYER_ENTERING_WORLD is the single most important WoW addon event —
virtually every addon registers for it to initialize UI, state, and
data structures. It was never fired, causing widespread addon init
failures on login and after teleports.

Now fired from:
- handleLoginVerifyWorld (initial login + same-map teleports)
- handleNewWorld (cross-map teleports, instance transitions)

Also fires:
- PLAYER_LOGIN on initial world entry only
- ZONE_CHANGED_NEW_AREA on all world entries
- UPDATE_WORLD_STATES on initial entry
- SPELLS_CHANGED + LEARNED_SPELL_IN_TAB after SMSG_INITIAL_SPELLS
  (so spell book addons can initialize on login)

Subject: [PATCH 257/435] feat: add GetPlayerFacing, GetCVar/SetCVar for
 minimap and addon settings

GetPlayerFacing() returns player orientation in radians, needed by
minimap addons for arrow rotation and facing-dependent mechanics.

GetCVar(name) returns sensible defaults for commonly queried CVars
(uiScale, screen dimensions, nameplate visibility, sound toggles,
autoLoot). SetCVar is a no-op stub for addon compatibility.

Subject: [PATCH 258/435] feat: add quest objective leaderboard API for
 WatchFrame quest tracking
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Implement GetNumQuestLeaderBoards and GetQuestLogLeaderBoard — the core
functions WatchFrame.lua and QuestLogFrame.lua use to display objective
progress like "Kobold Vermin slain: 3/8" or "Linen Cloth: 2/6".

GetNumQuestLeaderBoards counts kill + item objectives from the parsed
SMSG_QUEST_QUERY_RESPONSE data. GetQuestLogLeaderBoard returns the
formatted progress text, type ("monster"/"item"/"object"), and
completion status for each objective.

Also adds ExpandQuestHeader/CollapseQuestHeader (no-ops for flat quest
list) and GetQuestLogSpecialItemInfo stub.

In the CREATE update block, the ufNpcFlags check at the end of the
else-if chain was unreachable dead code — it was already handled
earlier in the same chain. Remove the duplicate.

In the VALUES update block, mount display changes via field updates
fired mountCallback_ but not the UNIT_MODEL_CHANGED addon event,
unlike the CREATE path which fired both. Add the missing event so
Lua addons are notified when the player mounts/dismounts via VALUES
updates (the common case for aura-based mounting).

Also fire UNIT_MODEL_CHANGED for target/focus/pet display ID changes
in the VALUES displayIdChanged path, matching the CREATE path behavior.

Subject: [PATCH 260/435] feat: implement GameTooltip methods with real
 item/spell/aura data
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Replace empty stub GameTooltip methods with working implementations:

- SetInventoryItem(unit, slot): populates tooltip with equipped item
  name and quality-colored text via GetInventoryItemLink + GetItemInfo
- SetBagItem(bag, slot): populates from GetContainerItemInfo + GetItemInfo
- SetSpellByID(spellId): populates with spell name/rank from GetSpellInfo
- SetAction(slot): delegates to SetSpellByID or item lookup via GetActionInfo
- SetUnitBuff/SetUnitDebuff: populates from UnitBuff/UnitDebuff data
- SetHyperlink: parses item: and spell: links to populate name
- GetItem/GetSpell: now return real item/spell data when tooltip is populated

Also fix GetCVar/SetCVar conflict — remove Lua-side overrides that
were shadowing the C-side implementations (which return real screen
dimensions and sensible defaults for common CVars).

Subject: [PATCH 261/435] feat: add world map navigation API for WorldMapFrame
 compatibility
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Implement the core map functions needed by WorldMapFrame.lua:
- SetMapToCurrentZone — sets map view from player's current mapId/zone
- GetCurrentMapContinent — returns continent (1=Kalimdor, 2=EK, etc.)
- GetCurrentMapZone — returns current zone ID
- SetMapZoom(continent, zone) — navigate map view
- GetMapContinents — returns continent name list
- GetMapZones(continent) — returns zone names per continent
- GetNumMapLandmarks — stub (returns 0)

Maps game mapId (0=EK, 1=Kalimdor, 530=Outland, 571=Northrend) to
WoW's continent numbering. Internal state tracks which continent/zone
the map UI is currently viewing.

Subject: [PATCH 262/435] fix: unify lava UV scroll timer across render passes
 to prevent flicker
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Lava M2 models used independent static-local start times in pass 1
and pass 2 for UV scroll animation. Since static locals initialize
on first call, the two timers started at slightly different times
(microseconds to frames apart), causing a permanent UV offset mismatch
between passes — visible as texture flicker/jumping on lava surfaces.

Replace both function-scoped statics with a single file-scoped
kLavaAnimStart constant, ensuring both passes compute identical UV
offsets from the same epoch.

Subject: [PATCH 263/435] feat: implement cursor/drag-drop system for action
 bar and inventory
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add the complete cursor state machine needed for drag-and-drop:
- PickupAction(slot) — pick up or swap action bar slots
- PlaceAction(slot) — place cursor content into action bar
- PickupSpell / PickupSpellBookItem — drag spells from spellbook
- PickupContainerItem(bag, slot) — drag items from bags
- PickupInventoryItem(slot) — drag equipped items
- ClearCursor / DeleteCursorItem — clear cursor state
- GetCursorInfo — returns cursor content type/id
- CursorHasItem / CursorHasSpell — query cursor state
- AutoEquipCursorItem — equip item from cursor

Cursor state tracks type (SPELL/ITEM/ACTION), id, and source slot.
PickupAction on empty slots with a spell cursor auto-assigns spells
to the action bar. Enables spellbook-to-action-bar drag-drop and
inventory management through the WoW UI.

Content-Transfer-Encoding: 8bit

Implement high-frequency FrameXML infrastructure functions:

- ShowUIPanel/HideUIPanel/ToggleFrame — UI panel show/hide (240+ calls
  in FrameXML). ShowUIPanel delegates to frame:Show(), HideUIPanel to
  frame:Hide().
- TEXT(str) — localization identity function (549 calls)
- FauxScrollFrame_GetOffset/Update/SetOffset/OnVerticalScroll — scroll
  list helpers used by quest log, guild roster, friends list, etc.
- SecureCmdOptionParse — basic macro conditional parser, returns
  unconditional fallback text
- ChatFrame_AddMessageGroup/RemoveMessageGroup/AddChannel/RemoveChannel
  — chat frame configuration stubs
- UIPanelWindows table, GetUIPanel, CloseWindows stubs

Subject: [PATCH 265/435] feat: fire CHAT_MSG_* events for all incoming chat
 messages

The SMSG_MESSAGECHAT handler stored messages in chatHistory and
triggered chat bubbles, but never fired Lua addon events. Chat frame
addons (Prat, Chatter, WIM) and the default ChatFrame all register for
CHAT_MSG_SAY, CHAT_MSG_WHISPER, CHAT_MSG_PARTY, CHAT_MSG_GUILD, etc.
to display incoming messages.

Now fires CHAT_MSG_{type} for every incoming message with the full WoW
event signature: message, senderName, language, channelName, displayName,
specialFlags, zoneChannelID, channelIndex, channelBaseName, unused,
lineID, and senderGUID. Covers all chat types: SAY, YELL, WHISPER,
PARTY, RAID, GUILD, OFFICER, CHANNEL, EMOTE, SYSTEM, MONSTER_SAY, etc.

Subject: [PATCH 266/435] fix: fire CHAT_MSG_* events for player's own messages
 and system text
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

addLocalChatMessage only pushed to chatHistory and called the C++
display callback — it never fired Lua addon events. This meant the
player's own sent messages (local echoes from sendChatMessage) and
system messages (loot, XP gains, errors) were invisible to Lua chat
frame addons.

Now fires CHAT_MSG_{type} with the full 12-arg WoW signature from
addLocalChatMessage, matching the incoming message path. Uses the
active character name as sender for player-originated messages.

Subject: [PATCH 267/435] fix: fire UNIT_AURA event for Classic/Turtle
 field-based aura updates
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Classic and Turtle WoW don't use SMSG_AURA_UPDATE packets — they
pack aura data into UNIT_FIELD_AURAS update fields. The code correctly
rebuilds playerAuras from these fields in both CREATE_OBJECT and VALUES
update paths, but never fired the UNIT_AURA("player") addon event.

Buff frame addons (Buffalo, ElkBuffBars, etc.) register for UNIT_AURA
to refresh their display. Without this event, buff frames on Classic
and Turtle never update when buffs are gained or lost.

Subject: [PATCH 268/435] feat: add UI_ERROR_MESSAGE events and quest removal
 notifications
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Fire UI_ERROR_MESSAGE from addUIError() so Lua addons can react to
error messages like "Not enough mana" or "Target is too far away".
Previously only the C++ overlay callback was notified. Also add
addUIInfoMessage() helper for informational system messages.

Fire QUEST_REMOVED and QUEST_LOG_UPDATE when quests are removed from
the quest log — both via server-driven removal (SMSG_QUEST_UPDATE_FAILED
etc.) and player-initiated abandon (CMSG_QUESTLOG_REMOVE_QUEST). Quest
tracking addons like Questie register for these events to update their
map markers and objective displays.

Subject: [PATCH 269/435] feat: add GetItemQualityColor, GetItemCount, and
 UseContainerItem

GetItemQualityColor(quality) returns r, g, b, hexString for item
quality coloring (Poor=gray through Heirloom=cyan). Used by bag
addons, tooltips, and item frames to color item names/borders.

GetItemCount(itemId) counts total stacks across backpack + bags.
Used by addons to check material availability, quest item counts,
and consumable tracking.

UseContainerItem(bag, slot) uses/equips an item from a container
slot, delegating to useItemById for the actual equip/use action.

 watch for raid frames
MIME-Version: 1.0

Content-Transfer-Encoding: 8bit

GetRaidRosterInfo(index) returns name, rank, subgroup, level, class,
fileName, zone, online, isDead, role, isML — the core function raid
frame addons (Grid, Healbot, VuhDo) use to populate unit frame data.
Resolves class from UNIT_FIELD_BYTES_0 when entity is available.

GetThreatStatusColor(status) returns RGB for threat indicator coloring
(gray/yellow/orange/red). Used by unit frames and threat meters.

GetReadyCheckStatus(unit) stub returns nil (no check in progress).
RegisterUnitWatch/UnregisterUnitWatch stubs for secure frame compat.

Subject: [PATCH 271/435] fix: color item links by quality in GetItemInfo and

GetItemInfo returned item links with hardcoded white color (|cFFFFFFFF)
regardless of quality. Now uses quality-appropriate colors: gray for

Epic, orange for Legendary, gold for Artifact, cyan for Heirloom.

Also fix GameTooltip:GetItem() to use the quality-colored link from
GetItemInfo instead of hardcoded white.

Subject: [PATCH 272/435] feat: add modifier key queries and IsModifiedClick
 for input handling
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Implement keyboard modifier state queries using ImGui IO state:
- IsShiftKeyDown, IsControlKeyDown, IsAltKeyDown — direct key queries
- IsModifiedClick(action) — checks if the modifier matching a named
  action is held (CHATLINK/SPLITSTACK=Shift, DRESSUP=Ctrl, SELFCAST=Alt)
- GetModifiedClick(action) — returns the assigned key name for an action
- SetModifiedClick — no-op stub for compatibility

These are fundamental input functions used by virtually all interactive
addons: shift-click to link items in chat, ctrl-click for dressup,
alt-click for self-cast, shift-click to split stacks, etc.

Subject: [PATCH 274/435] fix: include GCD in GetSpellCooldown and
 GetActionCooldown returns
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

GetSpellCooldown only returned per-spell cooldowns from the
spellCooldowns map, ignoring the Global Cooldown. Addons like OmniCC
and action bar addons rely on GetSpellCooldown returning GCD timing
when no individual spell cooldown is active — this is what drives the
cooldown sweep animation on action bar buttons after casting.

Now falls back to GCD timing (from getGCDRemaining/getGCDTotal) when
the spell has no individual cooldown but the GCD is active. Returns
proper (start, duration) values so addons can compute elapsed/remaining.

Same fix applied to GetActionCooldown for spell-type action bar slots.

PLAYER_DEAD only fired from SMSG_FORCED_DEATH_UPDATE (GM kill) — the
normal death path (health dropping to 0 via VALUES update) never fired
it. Death-related addons and the default release spirit dialog depend
on this event.

Also add PLAYER_ALIVE (fires when resurrected without having been a
ghost) and PLAYER_UNGHOST (fires when player rezzes from ghost form)
at the health-restored-from-zero VALUES path. These events control
the transition from ghost form back to alive, letting addons restore
normal UI state after death.

Subject: [PATCH 277/435] fix: fire ACTIONBAR_SLOT_CHANGED when assigning
 spells to action bar

setActionBarSlot (called from PickupAction/PlaceAction drag-drop and
from server-driven action button updates) updated the slot data and
notified the server, but never fired the Lua addon event. Action bar
addons (Bartender4, Dominos) register for ACTIONBAR_SLOT_CHANGED to
refresh button textures, tooltips, and cooldown state when slots change.

Also fires ACTIONBAR_UPDATE_STATE for general action bar refresh.

Subject: [PATCH 278/435] feat: add keybinding query API for action bar
 tooltips and binding UI
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Implement GetBindingKey(command) and GetBindingAction(key) with
default action button mappings (ACTIONBUTTON1-12 → "1"-"9","0","-","=").
Action bar addons display bound keys on button tooltips via
GetBindingKey("ACTIONBUTTON"..slot).

Also add stubs for GetNumBindings, GetBinding, SetBinding, SaveBindings,
SetOverrideBindingClick, and ClearOverrideBindings to prevent nil-call
errors in FrameXML keybinding UI code (37 call sites).

Subject: [PATCH 279/435] fix: unify time epoch across GetTime, cooldowns,
 auras, and cast bars
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Four independent static local steady_clock start times were used as
time origins in GetTime(), GetSpellCooldown(), UnitBuff expiration,
and UnitCastingInfo — each initializing on first call at slightly
different times. This created systematic timestamp mismatches.

When addons compute (start + duration - GetTime()), the start value
from GetSpellCooldown and the GetTime() return used different epochs,
causing cooldown sweeps and buff timers to appear offset.

Replace all four independent statics with a single file-scope
kLuaTimeEpoch constant and luaGetTimeNow() helper, ensuring all
time-returning Lua functions share exactly the same origin.

Subject: [PATCH 280/435] fix: populate item class, subclass, and equip slot in
 GetItemInfo

GetItemInfo returned empty strings for item class (field 6), subclass
(field 7), and equip slot (field 9). Now returns:

- Class: mapped from itemClass enum (Consumable, Weapon, Armor, etc.)
- Subclass: from parsed subclassName (Sword, Mace, Shield, etc.)
- EquipSlot: mapped from inventoryType to INVTYPE_ strings
  (INVTYPE_HEAD, INVTYPE_CHEST, INVTYPE_WEAPON, etc.)

These fields are used by equipment comparison addons, character sheet
displays, and bag sorting addons to categorize and filter items.

Subject: [PATCH 281/435] feat: enhance item tooltips with item level, equip
 slot, and subclass

Replace minimal name-only item tooltips with proper WoW-style display:
- Quality-colored item name header
- Item level line for equipment (gold text)
- Equip slot and weapon/armor type on a double line
  (e.g., "Head" / "Plate" or "One-Hand" / "Sword")
- Item class for non-equipment items

Shared _WoweePopulateItemTooltip() helper used by both
SetInventoryItem and SetBagItem for consistent tooltip formatting.
Maps INVTYPE_* strings to display names (Head, Chest, Two-Hand, etc.).

Subject: [PATCH 282/435] feat: add full item stat display to tooltips (armor,
 damage, stats, bind)

Enhance _WoweePopulateItemTooltip to show complete item information:
- Bind type (Binds when picked up / equipped / used)
- Armor value for armor items
- Weapon damage range, speed, and DPS for weapons
- Primary stats (+Stamina, +Strength, +Agility, +Intellect, +Spirit)
  in green text
- Required level
- Flavor/lore description text in gold

Backed by new _GetItemTooltipData(itemId) C function that returns a
Lua table with armor, bindType, damageMin/Max, speed, primary stats,
requiredLevel, and description from ItemQueryResponseData.

Subject: [PATCH 283/435] feat: add combat ratings, resistances to item tooltip
 display
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Extend item tooltips with secondary stats and resistances:

- Extra stats from ItemQueryResponseData.extraStats: Hit Rating,
  Crit Rating, Haste Rating, Resilience, Attack Power, Spell Power,
  Defense Rating, Dodge/Parry/Block Rating, Expertise, Armor Pen,
  Mana/Health per 5 sec, Spell Penetration — all in green text
- Elemental resistances: Fire/Nature/Frost/Shadow/Arcane Resistance

Also passes extraStats as an array of {type, value} pairs and
resistance fields through _GetItemTooltipData for Lua consumption.

Stat type IDs follow the WoW ItemMod enum (3=Agi, 7=Sta, 31=Hit,
32=Crit, 36=Haste, 45=SpellPower, etc.).

Subject: [PATCH 284/435] feat: show sell price on item tooltips in
 gold/silver/copper format

Item tooltips now display the vendor sell price at the bottom, formatted
as "Sell Price: 12g 50s 30c". Uses the vendorPrice field from GetItemInfo
(field 11, sourced from SMSG_ITEM_QUERY_SINGLE_RESPONSE sellPrice).

Helps players quickly assess item value when looting or sorting bags.

Subject: [PATCH 285/435] feat: enhance spell tooltips with cost, range, cast
 time, and cooldown

SetSpellByID now shows comprehensive spell information:
- Mana/Rage/Energy/Runic Power cost
- Range in yards (or omitted for self-cast)
- Cast time ("1.5 sec cast" or "Instant")
- Active cooldown remaining in red

Uses existing GetSpellInfo (castTime, range from DBC), GetSpellPowerCost
(mana cost from DBC), and GetSpellCooldown (remaining CD) to populate
the tooltip with real spell data.

Subject: [PATCH 286/435] fix: use rich tooltip display for SetAction items and
 SetHyperlink

SetAction's item branch and SetHyperlink's item/spell branches
showed only the item name, ignoring the full tooltip system we built.

SetAction item path now uses _WoweePopulateItemTooltip (shows armor,
stats, damage, bind type, sell price etc.).

SetHyperlink item path now uses _WoweePopulateItemTooltip; spell
path now uses SetSpellByID (shows cost, range, cast time, cooldown).

This means shift-clicking an item link in chat, hovering an item on
the action bar, or viewing any hyperlink tooltip now shows the full
stat breakdown instead of just the name.

Subject: [PATCH 287/435] feat: add RAID_ROSTER_UPDATE and UNIT_LEVEL events

RAID_ROSTER_UPDATE now fires alongside GROUP_ROSTER_UPDATE when the
group type is raid, matching the event that raid frame addons register
for (6 registrations in FrameXML). Fires from group list updates and
group uninvite handlers.

UNIT_LEVEL fires when any tracked unit (player, target, focus, pet)
changes level via VALUES update fields. Used by unit frame addons to
update level display (5 registrations in FrameXML).

 vendor addons
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Implement core vendor query functions from ListInventoryData:

- GetMerchantNumItems() — count of items for sale
- GetMerchantItemInfo(index) — name, texture, price, stackCount,
  numAvailable, isUsable for each vendor item
- GetMerchantItemLink(index) — quality-colored item link
- CanMerchantRepair() — whether vendor offers repair service

Enables auto-sell addons (AutoVendor, Scrap) to read vendor inventory
and check repair capability. Data sourced from SMSG_LIST_INVENTORY
via currentVendorItems + itemInfoCache for names/icons.

 sheet addons

UnitArmor(unit) returns base, effective, armor, posBuff, negBuff
matching WoW's 5-return signature. Uses server-authoritative armor
from UNIT_FIELD_RESISTANCES[0].

UnitResistance(unit, school) returns base, effective, posBuff, negBuff
for physical (school 0 = armor) and magical resistances (1-6:
Holy/Fire/Nature/Frost/Shadow/Arcane).

Needed by character sheet addons (PaperDollFrame, DejaCharacterStats)
to display armor and resistance values.

 changes
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When the player's mana/rage/energy changes, action bar addons need
ACTIONBAR_UPDATE_USABLE to update button dimming (grey out abilities
the player can't afford). Now fires from both the SMSG_POWER_UPDATE
handler and the SMSG_UPDATE_OBJECT VALUES power field change path.

Without this event, action bar buttons showed as usable even when the
player ran out of mana — the usability state only refreshed on spell
cast attempts, not on power changes.

Subject: [PATCH 292/435] feat: fire SPELL_UPDATE_USABLE alongside
 ACTIONBAR_UPDATE_USABLE

Some addons register for SPELL_UPDATE_USABLE instead of
ACTIONBAR_UPDATE_USABLE to detect when spell usability changes
due to power fluctuations. Fire both events together when the
player's mana/rage/energy changes.

Subject: [PATCH 293/435] feat: fire CHAT_MSG_ADDON for inter-addon
 communication messages

Detect addon messages in the SMSG_MESSAGECHAT handler by looking for
the 'prefix\ttext' format (tab delimiter). When detected, fire
CHAT_MSG_ADDON with args (prefix, message, channel, sender) instead
of the regular CHAT_MSG_* event, and suppress the raw message from
appearing in chat.

This enables inter-addon communication used by:
- Boss mods (DBM, BigWigs) for timer/alert synchronization
- Raid tools (oRA3) for ready checks and cooldown tracking
- Group coordination addons for pull countdowns and assignments

Works with the existing SendAddonMessage/RegisterAddonMessagePrefix
functions that format outgoing messages as 'prefix\ttext'.

UNIT_QUEST_LOG_CHANGED("player") now fires at all 6 locations where
QUEST_LOG_UPDATE fires — quest accept, complete, objective update,
abandon, and server-driven quest log changes. Some addons register
for this event instead of QUEST_LOG_UPDATE (4 registrations in
FrameXML). Both events are semantically equivalent for the player.

Subject: [PATCH 295/435] fix: tighten addon message detection to avoid
 suppressing regular chat
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The tab-based addon message detection was too aggressive — any chat
message containing a tab character was treated as an addon message
and silently dropped from regular chat display. This could suppress
legitimate player messages containing tabs (from copy-paste).

Now only matches as addon message when:
- Chat type is PARTY/RAID/GUILD/WHISPER/etc. (not SAY/YELL/EMOTE)
- Prefix before tab is <=16 chars (WoW addon prefix limit)
- Prefix contains no spaces (addon prefixes are identifiers)

This prevents false positives while still correctly detecting addon
messages formatted as "DBM4\ttimer:start:10".

DISPLAY_SIZE_CHANGED fires when the window is resized via
SDL_WINDOWEVENT_RESIZED, allowing UI addons to adapt their layout
to the new screen dimensions (5 FrameXML registrations).

UNIT_QUEST_LOG_CHANGED("player") fires alongside QUEST_LOG_UPDATE
at all 6 quest log modification points, for addons that register
for this variant instead (4 FrameXML registrations).

Subject: [PATCH 297/435] feat: wire PlaySound to real audio engine for addon
 sound feedback
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Replace PlaySound no-op stub with a real implementation that maps
WoW sound IDs and names to the UiSoundManager methods:

By ID: 856/1115→button click, 840→quest activate, 841→quest complete,
       862→bag open, 863→bag close, 888→level up
By name: IGMAINMENUOPTION→click, IGQUESTLISTOPEN→quest activate,
         IGQUESTLISTCOMPLETE→quest complete, IGBACKPACKOPEN/CLOSE→bags,
         LEVELUPSOUND→level up, TALENTSCREEN→character sheet

This gives addons audio feedback when they call PlaySound() — button
clicks, quest sounds, and other UI sounds now actually play instead
of being silently swallowed.

Subject: [PATCH 298/435] feat: add UnitRage, UnitEnergy, UnitFocus,
 UnitRunicPower aliases
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Register power-type-specific aliases (UnitRage, UnitEnergy, UnitFocus,
UnitRunicPower) that map to the existing lua_UnitPower function. Some
Classic/TBC addons call these directly instead of the generic UnitPower.
All return the unit's current power value regardless of type — the
underlying function reads from the entity's power field.

Add gem socket display to item tooltips — shows [Meta Socket],
[Red Socket], [Yellow Socket], [Blue Socket], or [Prismatic Socket]
based on socketColor mask from ItemQueryResponseData.

Also pass itemSetId through _GetItemTooltipData for addons that
track set bonuses.

Subject: [PATCH 300/435] feat: add spell descriptions to tooltips via
 GetSpellDescription
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Spell tooltips now show the spell description text (e.g., "Hurls a
fiery ball that causes 565 to 655 Fire Damage") in gold/yellow text
between the cast info and cooldown display.

New GetSpellDescription(spellId) C function exposes the description
field from SpellNameEntry (loaded from Spell.dbc via the spell name
cache). Descriptions contain the raw DBC text which may include
template variables ($s1, $d, etc.) — these show as-is until template
substitution is implemented.

Subject: [PATCH 301/435] feat: show item spell effects in tooltips
 (Use/Equip/Chance on Hit)

Item tooltips now display spell effects in green text:
- "Use: Restores 2200 health over 30 sec" (trigger 0)
- "Equip: Increases attack power by 120" (trigger 1)
- "Chance on hit: Strikes the enemy for 95 Nature damage" (trigger 2)

Passes up to 5 item spell entries through _GetItemTooltipData with
spellId, trigger type, spell name, and spell description from DBC.
The tooltip builder maps trigger IDs to "Use: ", "Equip: ", or
"Chance on hit: " prefixes.

This completes the item tooltip with all major WoW tooltip sections:
quality name, bind type, equip slot/type, armor, damage/DPS/speed,
primary stats, combat ratings, resistances, spell effects, gem sockets,
required level, flavor text, and sell price.

Subject: [PATCH 302/435] feat: show Unique and Heroic tags on item tooltips

Items with maxCount=1 now show "Unique" in white text below the name.
Items with the Heroic flag (0x8) show "Heroic" in green text. Both
display before the bind type line, matching WoW's tooltip order.

Heroic items (from heroic dungeon/raid drops) are visually
distinguished from their normal-mode counterparts. Unique items
(trinkets, quest items, etc.) show the carry limit clearly.

Subject: [PATCH 303/435] fix: populate item subclass names for TBC expansion

The TBC item query parser left subclassName empty, so TBC items showed
no weapon/armor type in tooltips or the character sheet (e.g., "Sword",
"Plate", "Shield" were all blank). The Classic and WotLK parsers
correctly map subClass IDs to names.

Fix: call getItemSubclassName() in the TBC parser, same as WotLK.
Expose getItemSubclassName() in the header (was static, now shared
across parser files).

Lua addons. Rogue/druid combo point displays and DPS rotation addons

LOOT_READY fires alongside LOOT_OPENED when a loot window opens. Some
addons register for this WoW 5.x+ event name instead of LOOT_OPENED.

Subject: [PATCH 305/435] feat: fire CURRENT_SPELL_CAST_CHANGED when player
 begins casting

CURRENT_SPELL_CAST_CHANGED fires when the player starts a new cast
via handleSpellStart. Some addons register for this as a catch-all
signal that the current spell state changed, complementing the more
specific UNIT_SPELLCAST_START/STOP/FAILED events.

Subject: [PATCH 306/435] feat: add GetMaxPlayerLevel and
 GetAccountExpansionLevel

GetMaxPlayerLevel() returns the level cap for the active expansion:
60 (Classic/Turtle), 70 (TBC), 80 (WotLK). Used by XP bar addons
and leveling trackers.

GetAccountExpansionLevel() returns the expansion tier: 1 (Classic),
2 (TBC), 3 (WotLK). Used by addons that adapt features based on
which expansion is active.

Both read from the ExpansionRegistry's active profile at runtime.

 UI coloring

GetClassColor(className) returns r, g, b, colorString from the
RAID_CLASS_COLORS table. Used by unit frame addons, chat addons,

QuestDifficultyColors table provides standard quest difficulty
color mappings (impossible=red, verydifficult=orange, difficult=yellow,
standard=green, trivial=gray, header=gold). Used by quest log and
quest tracker addons for level-appropriate coloring.

 targeting stubs
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

SpellStopCasting() cancels the current cast via cancelCast(). Used by
macro addons and cast-cancel logic (e.g., /stopcasting macro command).

UnitFullName/GetUnitName aliases for UnitName — some addons use these
variant names.

SpellIsTargeting() returns false (no AoE targeting reticle in this
client). SpellStopTargeting() is a no-op stub. Both prevent errors
in addons that check targeting state.

 utilities
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Implement the WoW Mixin pattern used by modern addons:
- Mixin(obj, ...) — copies fields from mixin tables into obj
- CreateFromMixins(...) — creates a new table from mixin templates
- CreateAndInitFromMixin(mixin, ...) — creates and calls Init()
- MergeTable(dest, src) — shallow-merge src into dest

These enable OOP-style addon architecture used by LibSharedMedia,
WeakAuras, and many Ace3-based addons for class/object creation.

Subject: [PATCH 311/435] feat: clean spell description template variables for
 readable tooltips
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Spell descriptions from DBC contain raw template variables like
\$s1, \$d, \$o1 that refer to effect values resolved at runtime.
Without DBC effect data loaded, these showed as literal "\$s1" in
tooltips, making descriptions hard to read.

Now strips template variables and replaces with readable placeholders:
- \$s1/\$s2/\$s3 → "X" (effect base points)
- \$d → "X sec" (duration)
- \$o1 → "X" (periodic total)
- \$a1 → "X" (radius)
- \$\$ → "$" (literal dollar sign)
- \${...} blocks → stripped

Result: "Hurls a fiery ball that causes X Fire Damage" instead of
"Hurls a fiery ball that causes \$s1 Fire Damage". Not as informative
as real values, but significantly more readable.

Subject: [PATCH 312/435] feat: add GetEnchantInfo for enchantment name
 resolution

GetEnchantInfo(enchantId) looks up the enchantment name from
SpellItemEnchantment.dbc (field 14). Returns the display name
like "Crusader", "+22 Intellect", or "Mongoose" for a given
enchant ID.

Used by equipment comparison addons and tooltip addons to display
enchantment names on equipped gear. The enchant ID comes from the
item's ITEM_FIELD_ENCHANTMENT update field.

Also adds getEnchantName() to GameHandler for C++ access.

Subject: [PATCH 313/435] feat: track shapeshift form and fire
 UPDATE_SHAPESHIFT_FORM events
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add UNIT_FIELD_BYTES_1 to all expansion update field tables (Classic=133,
TBC/WotLK=137). Byte 3 of this field contains the shapeshift form ID
(Bear=1, Cat=3, Travel=4, Moonkin=31, Tree=36, Battle Stance=17, etc.).

Track form changes in the VALUES update handler and fire
UPDATE_SHAPESHIFT_FORM + UPDATE_SHAPESHIFT_FORMS events when the
form changes. This enables stance bar addons and druid form tracking.

New Lua functions:
- GetShapeshiftForm() — returns current form ID (0 = no form)
- GetNumShapeshiftForms() — returns form count by class (Warrior=3,
  Druid=6, DK=3, Rogue=1, Priest=1, Paladin=3)

Subject: [PATCH 314/435] feat: add GetShapeshiftFormInfo for stance/form bar
 display

GetShapeshiftFormInfo(index) returns icon, name, isActive, isCastable
for each shapeshift form slot. Provides complete form tables for:

- Warrior: Battle Stance, Defensive Stance, Berserker Stance
- Druid: Bear, Travel, Cat, Swift Flight, Moonkin, Tree of Life
- Death Knight: Blood/Frost/Unholy Presence
- Rogue: Stealth

isActive is true when the form matches the current shapeshiftFormId_.
GetShapeshiftFormCooldown stub returns no cooldown.

Together with GetShapeshiftForm and GetNumShapeshiftForms from the
previous commit, this completes the stance bar API that addons use
to render and interact with form/stance buttons.

Subject: [PATCH 315/435] feat: add CastShapeshiftForm and CancelShapeshiftForm
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

CastShapeshiftForm(index) casts the spell for the given form slot:
- Warrior: Battle Stance(2457), Defensive(71), Berserker(2458)
- Druid: Bear(5487), Travel(783), Cat(768), Flight(40120),
  Moonkin(24858), Tree(33891)
- Death Knight: Blood(48266), Frost(48263), Unholy(48265)
- Rogue: Stealth(1784)

This makes stance bar buttons functional — clicking a form button
actually casts the corresponding spell to switch forms.

CancelShapeshiftForm stub for cancelling current form.

GetActionBarPage() returns the current action bar page (1-6).
ChangeActionBarPage(page) switches pages and fires ACTIONBAR_PAGE_CHANGED

default UI's page arrows / shift+number keybinds.

Implement pet action bar functions using existing pet data:

- HasPetUI() — whether player has an active pet
- GetPetActionInfo(index) — name, icon, isActive, autoCastEnabled
  for each of the 10 pet action bar slots
- GetPetActionCooldown(index) — cooldown state stub
- PetAttack() — send attack command to current target
- PetFollow() — send follow command
- PetWait() — send stay command
- PetPassiveMode() — set passive react mode
- PetDefensiveMode() — set defensive react mode

All backed by existing SMSG_PET_SPELLS data (petActionSlots_,

Subject: [PATCH 318/435] feat: add CastPetAction, TogglePetAutocast,
 PetDismiss, IsPetAttackActive
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Complete the pet action bar interaction:

- CastPetAction(index) — cast the pet spell at the given bar slot
  by sending the packed action via sendPetAction
- TogglePetAutocast(index) — toggle autocast for the pet spell
  at the given slot via togglePetSpellAutocast
- PetDismiss() — send dismiss pet command
- IsPetAttackActive() — whether pet is currently in attack mode

Together with the previous pet bar functions (HasPetUI, GetPetActionInfo,
PetAttack, PetFollow, PetWait, PetPassiveMode, PetDefensiveMode), this
completes the pet action bar system for hunters/warlocks/DKs.

Subject: [PATCH 319/435] feat: add achievement API (GetAchievementInfo,
 GetNumCompleted)

GetNumCompletedAchievements() returns count of earned achievements.
GetAchievementInfo(id) returns the full 12-field WoW API signature:
id, name, points, completed, month, day, year, description, flags,
icon, rewardText, isGuildAchievement.

Uses existing earnedAchievements_ set, achievement name/description/
points caches from Achievement.dbc, and completion date tracking
from SMSG_ALL_ACHIEVEMENT_DATA / SMSG_ACHIEVEMENT_EARNED.

Enables achievement tracking addons (Overachiever, etc.) to query
and display achievement progress.

GetNumGlyphSockets() returns 6 (WotLK glyph slot count).
GetGlyphSocketInfo(index, talentGroup) returns enabled, glyphType
(1=major, 2=minor), glyphSpellID, and icon for each socket.

Uses existing learnedGlyphs_ array populated from SMSG_TALENTS_INFO.
Enables talent/glyph inspection addons.

This commit brings the total API count to exactly 400 functions.

Subject: [PATCH 322/435] feat: add auction house API for Auctioneer and AH
 addons

GetNumAuctionItems(listType) returns item count and total for
browse/owner/bidder lists. GetAuctionItemInfo(type, index) returns
the full 17-field WoW API signature: name, texture, count, quality,
canUse, level, minBid, minIncrement, buyoutPrice, bidAmount,
highBidder, owner, saleStatus, itemId.

GetAuctionItemTimeLeft(type, index) returns time category 1-4
(short/medium/long/very long).

Uses existing auctionBrowseResults_, auctionOwnerResults_, and
auctionBidderResults_ from SMSG_AUCTION_LIST_RESULT. Enables
Auctioneer, Auctionator, and AH scanning addons.

Subject: [PATCH 324/435] feat: add trade API (AcceptTrade, CancelTrade,
 InitiateTrade)

AcceptTrade() locks in the trade offer via CMSG_ACCEPT_TRADE.
CancelTrade() cancels an open trade via CMSG_CANCEL_TRADE.
InitiateTrade(unit) starts a trade with a target player.

Uses existing GameHandler trade functions and TradeStatus tracking.
Enables trade addons and macro-based trade acceptance.

 addons
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

RepairAllItems(useGuildBank) sends CMSG_REPAIR_ITEM to repair all
equipped items at the current vendor. Checks CanMerchantRepair before
sending. Optional useGuildBank flag for guild bank repairs.

One of the most commonly needed addon functions — enables auto-repair
addons to fix all gear in a single call when visiting a repair vendor.

 vendor interaction

BuyMerchantItem(index, count) purchases an item from the current
vendor by merchant slot index. Resolves itemId and slot from the
vendor's ListInventoryData.

SellContainerItem(bag, slot) sells an item from the player's
inventory to the vendor. Supports backpack (bag=0) and bags 1-4.

Enables auto-sell addons (Scrap, AutoVendor) and vendor UI addons
to buy/sell items programmatically.

 stub

GuildRoster() triggers CMSG_GUILD_ROSTER to request updated guild
member data from the server. Called by guild roster addons and the
social panel to refresh the member list.

SortGuildRoster() is a no-op (sorting is handled client-side by
the ImGui guild roster display).

Subject: [PATCH 328/435] feat: add WEATHER_CHANGED event and GetWeatherInfo
 query

Fire WEATHER_CHANGED(weatherType, intensity) when the server sends
SMSG_WEATHER with a new weather state. Enables weather-aware addons
to react to rain/snow/storm transitions.

GetWeatherInfo() returns current weatherType (0=clear, 1=rain, 2=snow,
3=storm) and intensity (0.0-1.0). Weather data is already tracked by
game_handler and used by the renderer for particle effects and fog.

Subject: [PATCH 329/435] feat: add GetDifficultyInfo for instance difficulty
 display

GetDifficultyInfo(id) returns name, groupType, isHeroic, maxPlayers
for WotLK instance difficulties:
  0: "5 Player" (party, normal, 5)
  1: "5 Player (Heroic)" (party, heroic, 5)
  2: "10 Player" (raid, normal, 10)
  3: "25 Player" (raid, normal, 25)
  4/5: 10/25 Heroic raids

Used by boss mod addons (DBM, BigWigs) and instance info displays
to show the current dungeon difficulty.

CalendarGetDate() returns real weekday, month, day, year from the
system clock. Used by calendar addons and date-aware UI elements.

CalendarGetNumPendingInvites() and CalendarGetNumDayEvents() return 0
as stubs — prevents nil errors in addons that check calendar state.

Subject: [PATCH 331/435] feat: resolve spell \$s1/\$s2/\$s3 to real DBC
 damage/heal values
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Spell descriptions now substitute \$s1/\$s2/\$s3 template variables
with actual effect base points from Spell.dbc (field 80/81/82).
For example: "causes \$s1 Fire Damage" → "causes 562 Fire Damage".

Implementation:
- Added EffectBasePoints0/1/2 to all 4 expansion DBC layouts
- SpellNameEntry now stores effectBasePoints[3]
- loadSpellNameCache reads base points during DBC iteration
- cleanSpellDescription substitutes \$s1→abs(base)+1 when available
- getSpellEffectBasePoints() accessor on GameHandler

Values are DBC base points (before spell power scaling). Still uses
"X" placeholder for unresolved variables (\$d, \$o1, etc.).

Subject: [PATCH 332/435] feat: resolve spell \$d duration to real seconds from
 SpellDuration.dbc
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Spell descriptions now substitute \$d with actual duration values:
  Before: "X damage over X sec"
  After:  "30 damage over 18 sec"

Implementation:
- DurationIndex field (40) added to all expansion Spell.dbc layouts
- SpellDuration.dbc loaded during cache build: maps index → base ms
- cleanSpellDescription substitutes \$d with resolved seconds/minutes
- getSpellDuration() accessor on GameHandler

Combined with \$s1/\$s2/\$s3 from the previous commit, most common
spell description templates are now fully resolved with real values.

Spell descriptions now substitute \$o1/\$o2/\$o3 with the total
periodic damage/healing: base_per_tick × (duration / 3sec).

Example: SW:Pain with base=4 (5 per tick), duration=18sec (6 ticks):
  Before: "Causes X Shadow damage over 18 sec"
  After:  "Causes 30 Shadow damage over 18 sec"

Combined with \$s1 (per-tick/instant) and \$d (duration), the three
most common spell template variables are now fully resolved. This
covers the vast majority of spell tooltips.

Subject: [PATCH 334/435] feat: show 'This Item Begins a Quest' on
 quest-starting item tooltips

Items with a startQuestId now display "This Item Begins a Quest" in
gold text at the bottom of the tooltip, matching WoW's behavior.
Helps players identify quest-starting drops in their inventory.

Passes startsQuest flag through _GetItemTooltipData from the
startQuestId field in ItemQueryResponseData.

Items with the Unique-Equipped flag (itemFlags & 0x1000000) now
display "Unique-Equipped" in the tooltip header. This is distinct
from "Unique" (maxCount=1) — Unique-Equipped means you can carry
multiple but only equip one (e.g., trinkets, rings with the flag).

UnitIsPVP(unit) checks UNIT_FLAG_PVP (0x1000) on the unit's flags
field. Used by unit frame addons to show PvP status indicators.

UnitIsPVPFreeForAll(unit) checks for FFA PvP flag.

GetBattlefieldStatus() returns stub ("none") for addons that check
BG queue state on login. Full BG scoreboard data exists in
GameHandler but is rendered via ImGui.

Subject: [PATCH 337/435] feat: add battleground scoreboard API for PvP addons

GetNumBattlefieldScores() returns player count in the BG scoreboard.
GetBattlefieldScore(index) returns 12-field WoW API signature: name,
killingBlows, honorableKills, deaths, honorGained, faction, rank,
race, class, classToken, damageDone, healingDone.

GetBattlefieldWinner() returns winning faction (0=Horde, 1=Alliance)
or nil if BG is still in progress.

RequestBattlefieldScoreData() sends MSG_PVP_LOG_DATA to refresh the
scoreboard from the server.

Uses existing BgScoreboardData from MSG_PVP_LOG_DATA handler.
Enables BG scoreboard addons and PvP tracking.

Subject: [PATCH 338/435] feat: add instance lockout API for raid reset
 tracking

GetNumSavedInstances() returns count of saved instance lockouts.
GetSavedInstanceInfo(index) returns 9-field WoW signature: name,
mapId, resetTimeRemaining, difficulty, locked, extended,
instanceIDMostSig, isRaid, maxPlayers.

Uses existing instanceLockouts_ from SMSG_RAID_INSTANCE_INFO.
Enables SavedInstances and lockout tracking addons to display
which raids/dungeons the player is locked to and when they reset.

 addons
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

GetInspectSpecialization() returns the inspected player's active
talent group from the cached InspectResult data.

NotifyInspect() and ClearInspectPlayer() are stubs — inspection is
auto-triggered by the C++ side when targeting players. These prevent
nil errors in inspection addons that call them.

Subject: [PATCH 353/435] feat: add quest interaction (accept, decline,
 complete, abandon, rewards)

AcceptQuest() / DeclineQuest() respond to quest offer dialogs.
CompleteQuest() sends quest completion to server.
AbandonQuest(questId) abandons a quest from the quest log.
GetNumQuestRewards() / GetNumQuestChoices() return reward counts
for the selected quest log entry.

Backed by existing GameHandler methods. Enables quest helper addons
to accept/decline/complete quests programmatically.

Subject: [PATCH 354/435] feat: add taxi/flight path API (NumTaxiNodes,
 TaxiNodeName, TakeTaxiNode)

NumTaxiNodes() returns the count of taxi nodes available at the
current flight master. TaxiNodeName(index) returns the node name.
TaxiNodeGetType(index) returns whether the node is known/reachable.
TakeTaxiNode(index) activates the flight to the selected node.

Uses existing taxiNodes_ data and activateTaxi() method.
Enables flight path addons and taxi map overlay addons.

 AcceptBattlefieldPort (BG queue)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

GetNetStats() returns bandwidthIn, bandwidthOut, latencyHome,
latencyWorld — with real latency from getLatencyMs(). Used by
latency display addons and the default UI's network indicator.

AcceptBattlefieldPort(index, accept) accepts or declines a
battleground queue invitation. Backed by existing acceptBattlefield
and declineBattlefield methods.

Subject: [PATCH 356/435] fix: auto-detect CharSections.dbc layout and add
 Blood Elf/Draenei NPC voices
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

CharSections.dbc has different field layouts between stock WotLK (textures
at field 4-6) and Classic/TBC/Turtle/HD-textured WotLK (VariationIndex at
field 4). Add detectCharSectionsFields() that probes field-4 values at
runtime to determine the correct layout, so both stock and modded clients
work without JSON changes.

Also add BLOODELF_MALE/FEMALE and DRAENEI_MALE/FEMALE voice types to the
NPC voice system — previously all Blood Elf and Draenei NPCs fell through
to GENERIC (random dwarf/gnome/night elf/orc mix).

Subject: [PATCH 357/435] fix: validate splineMode in Classic spline parse to
 prevent desync
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When a WotLK NPC has durationMod=0.0, the Classic-first spline parser
reads it as pointCount=0 and "succeeds", then consumes garbage bytes as
splineMode and endPoint. This desynchronizes the read position for all
subsequent update blocks in the packet, causing cascading failures
(truncated update mask, unknown update type) that leave NPCs without
displayIds — making them invisible.

Fix: after reading splineMode, reject the Classic parse if splineMode > 3
(valid values are 0-3) and fall through to the WotLK format parser.

Subject: [PATCH 358/435] fix: read unconditional parabolic fields in WotLK
 spline parsing
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

AzerothCore/ChromieCraft always writes verticalAcceleration(float) +
effectStartTime(uint32) after durationMod in the spline movement block,
regardless of whether the PARABOLIC spline flag (0x800) is set. The
parser only read these 8 bytes when PARABOLIC was flagged, causing it
to read the wrong offset as pointCount (0 instead of e.g. 11). This
made every patrolling NPC fail to parse — invisible with no displayId.

Also fix splineStart calculation (was off by 4 bytes) and remove
temporary diagnostic logging.

The wall/floor classification threshold was lowered from 0.65 to 0.35
in a prior optimization commit, causing surfaces at 35-65° from
horizontal (steep walls, angled building geometry) to be classified as
floors and skipped during wall collision. This allowed the player to
clip through angled WMO walls.

Restore the threshold to 0.65 (cos 50°) in both the collision grid
builder and the runtime checkWallCollision skip, matching the
MAX_WALK_SLOPE limit used for slope-slide physics.

Subject: [PATCH 360/435] fix: stop sending CMSG_LOOT after CMSG_GAMEOBJ_USE
 (releases server loot)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

AzerothCore handles loot automatically in the CMSG_GAMEOBJ_USE handler
(calls SendLoot internally). Sending a redundant CMSG_LOOT 200ms later
triggers DoLootRelease() on the server, which closes the loot the server
just opened — before SMSG_LOOT_RESPONSE ever reaches the client. This
broke quest GO interactions (Bundle of Wood, etc.) because the loot
window never appeared and quest items were never granted.

Also remove temporary diagnostic logging from GO interaction path.

Subject: [PATCH 361/435] fix: direct CMSG_LOOT for chest GOs and increase M2
 descriptor pools
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Chest-type game objects (quest pickups, treasure chests) now send
CMSG_LOOT directly with the GO GUID instead of CMSG_GAMEOBJ_USE +
delayed CMSG_LOOT. The server's loot handler activates the GO and
sends SMSG_LOOT_RESPONSE in one step. The old approach failed because
CMSG_GAMEOBJ_USE opened+despawned the GO before CMSG_LOOT arrived.

Double M2 bone and material descriptor pool sizes (8192 → 16384) to
handle the increased NPC count from the spline parsing fix — patrolling
NPCs that were previously invisible now spawn correctly, exhausting
the old pool limits.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Chest-type GOs now send CMSG_GAMEOBJ_USE immediately followed by
CMSG_LOOT in the same frame. The USE handler opens the chest, then the
LOOT handler reads the contents — both processed sequentially by the
server. Previously only CMSG_LOOT was sent (no USE), which failed on
AzerothCore because the chest wasn't activated first.

Reset the Bags window position to bottom-right if the saved position
is outside the current screen resolution (e.g. after a resolution
change or moving between monitors).

Subject: [PATCH 363/435] fix: allow closing any bag independently and reset
 off-screen positions

Remove the forced backpack-open constraint that prevented closing the
backpack while other bags were open. Each bag window is now independently
closable regardless of which others are open.

Add off-screen position reset to individual bag windows (renderBagWindow)
so bags saved at positions outside the current resolution snap back to
their default stack position.

Subject: [PATCH 364/435] fix: enable Vulkan portability drivers on macOS for
 MoltenVK compatibility

Homebrew's vulkan-loader hides portability ICDs (like MoltenVK) from
pre-instance extension enumeration by default, causing SDL2 to fail
with "doesn't implement VK_KHR_surface". Set VK_LOADER_ENABLE_PORTABILITY_DRIVERS
before loading the Vulkan library so the loader includes MoltenVK and
its surface extensions.

Subject: [PATCH 365/435] fix: suppress false-positive maskBlockCount warnings
 for VALUES updates

VALUES update blocks don't carry an objectType field (it defaults to 0),
so the sanity check incorrectly used the non-PLAYER threshold (10) for
player character updates that legitimately need 42-46 mask blocks. Allow
up to 55 blocks for VALUES updates (could be any entity type including
PLAYER). Only enforce strict limits on CREATE_OBJECT blocks where the
objectType is known.

Subject: [PATCH 368/435] feat: server-synced bag sort, fix world map continent
 bounds, update docs
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Inventory sort: clicking "Sort Bags" now generates CMSG_SWAP_ITEM packets
to move items server-side (one swap per frame to avoid race conditions).
Client-side sort runs immediately for visual preview; server swaps follow.
New Inventory::computeSortSwaps() computes minimal swap sequence using
selection-sort permutation on quality→itemId→stackCount comparator.

World map: fix continent bounds derivation that used intersection (max/min)
instead of union (min/max) of child zone bounds, causing continent views
to display zoomed-in/clipped.

Update README.md and docs/status.md with current features, release info,
and known gaps (v1.8.2-preview, 664 opcode handlers, NPC voices, bag
independence, CharSections auto-detect, quest GO server limitation).

Subject: [PATCH 369/435] perf: add Vulkan pipeline cache persistence for
 faster startup

Create a VkPipelineCache at device init, loaded from disk if available.
All 65 pipeline creation calls across 19 renderer files now use the
shared cache. On shutdown, the cache is serialized to disk so subsequent
launches skip redundant shader compilation.

Cache path: ~/.local/share/wowee/pipeline_cache.bin (Linux),
~/Library/Caches/wowee/ (macOS), %APPDATA%\wowee\ (Windows).
Stale/corrupt caches are handled gracefully (fallback to empty cache).

Subject: [PATCH 371/435] feat: log GPU vendor/name at init, add PLAY_SOUND
 diagnostics

Log GPU name and vendor ID during VkContext initialization for easier
debugging of GPU-specific issues (FSR3, driver compat, etc.). Add
isAmdGpu()/isNvidiaGpu() accessors.

Temporarily log SMSG_PLAY_SOUND and SMSG_PLAY_OBJECT_SOUND at WARN
level (sound ID, name, file path) to diagnose unidentified ambient
NPC sounds reported by the user.

Subject: [PATCH 372/435] fix: prevent hang on FSR3 upscale context creation
 failure
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When ffxCreateContext for the upscaler fails (e.g. on NVIDIA with the
AMD FidelityFX runtime), the shutdown() path called dlclose() on the
runtime library which could hang — the library's global destructors may
block waiting for GPU operations that never completed.

Skip dlclose() on context creation failure: just clean up function
pointers and mark as failed. The library stays loaded (harmless) and
the game continues with FSR2 fallback instead of hanging.

The AMD FidelityFX FSR3 runtime corrupts Vulkan driver state when
context creation fails on NVIDIA GPUs, causing vkCmdBeginRenderPass
to SIGSEGV inside libnvidia-glcore. Gate FSR3 frame gen initialization
behind isAmdGpu() check — FSR2 upscaling still works on all GPUs.

Subject: [PATCH 375/435] fix: convert PLAY_OBJECT_SOUND positions to render
 coords for 3D audio

Entity positions are in canonical WoW coords (X=north, Y=west) but the
audio listener uses render coords (X=west, Y=north) from the camera.
Without conversion, distance attenuation was computed on swapped axes,
making NPC ambient sounds (peasant voices, etc.) play at wrong volumes
regardless of actual distance.

Subject: [PATCH 376/435] fix: skip VkPipelineCache on NVIDIA to prevent driver
 crash
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

VkPipelineCache causes vkCmdBeginRenderPass to SIGSEGV inside
libnvidia-glcore.so on NVIDIA 590.x drivers. Skip pipeline cache
creation on NVIDIA GPUs — NVIDIA drivers already provide built-in
shader disk caching, so the Vulkan-level cache is redundant.
Pipeline cache still works on AMD and other vendors.

Subject: [PATCH 377/435] fix: add VkSampler cache to prevent sampler
 exhaustion crash
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Validation layers revealed 9965 VkSamplers allocated against a device
limit of 4000 — every VkTexture created its own sampler even when
configurations were identical. This exhausted NVIDIA's sampler pool
and caused intermittent SIGSEGV in vkCmdBeginRenderPass.

Add a thread-safe sampler cache in VkContext that deduplicates samplers
by FNV-1a hash of all 14 VkSamplerCreateInfo fields. All texture,
render target, renderer, water, and loading screen sampler creation
now goes through getOrCreateSampler(). Textures set ownsSampler_=false
so shared samplers aren't double-freed.

Also auto-disable anisotropy in the cache when the physical device
doesn't support the samplerAnisotropy feature, fixing the validation
error VUID-VkSamplerCreateInfo-anisotropyEnable-01070.

Subject: [PATCH 378/435] fix: track render pass subpass mode to prevent ImGui
 secondary violation
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When parallel recording is active, the scene pass uses
VK_SUBPASS_CONTENTS_SECONDARY_COMMAND_BUFFERS. Post-processing paths
(FSR/FXAA) end the scene pass and begin a new INLINE render pass for
the swapchain output. ImGui rendering must use the correct mode —
secondary buffers for SECONDARY passes, direct calls for INLINE.

Previously the check used a static condition based on enabled features
(!fsr && !fsr2 && !fxaa && parallel), which could mismatch if a
feature was enabled but initialization failed. Replace with
endFrameInlineMode_ flag that tracks the actual current render pass
mode at runtime, eliminating the validation error
VUID-vkCmdDrawIndexed-commandBuffer-recording that caused intermittent
NVIDIA driver crashes.

Add mapDisplayName() with friendly names for continents: "Eastern

previously showed WDT directory names like "Expansion01" when
Map.dbc's localized name field was empty or matched the internal name.

Subject: [PATCH 380/435] fix: flush GPU before first render frame after world
 load

Add vkDeviceWaitIdle after world loading completes to ensure all async
texture uploads and resource creation are fully flushed before the
first render frame. Mitigates intermittent NVIDIA driver crashes at
vkCmdBeginRenderPass during initial world entry.

Subject: [PATCH 381/435] fix: correct melee swing sound paths to match WoW MPQ
 layout

The melee swing clips used non-existent paths (SwordSwing, MeleeSwing)
instead of the actual WoW 3.3.5a weapon swing files: WeaponSwings/
mWooshMedium and mWooshLarge for hit swings, MissSwings/MissWhoosh
for misses. Fixes "No melee swing SFX found in assets" warning.

Subject: [PATCH 382/435] perf: time-budget tile finalization to prevent 1+
 second main-loop stalls

processReadyTiles was calling advanceFinalization with a step limit of 1
but a single step (texture upload or M2 model load) could take 1060ms.
Replace the step counter with an 8ms wall-clock time budget (16ms during
taxi) so finalization yields to the render loop before causing a visible
stall. Heavy tiles spread across multiple frames instead of blocking.

Subject: [PATCH 383/435] perf: use second GPU queue for parallel
 texture/buffer uploads

Request 2 queues from the graphics family when available (NVIDIA
exposes 16, AMD 2+). Upload batches now submit to queue[1] while
rendering uses queue[0], enabling parallel GPU transfers without
queue-family ownership transfer barriers (same family).

Falls back to single-queue path on GPUs with only 1 queue in the
graphics family. Transfer command pool is separate to avoid contention.

Subject: [PATCH 384/435] feat: enable crafting sounds and add Create All
 button

Remove the isProfessionSpell sound suppression so crafting spells play
precast and cast-complete audio like combat spells. Crafting was
previously silent by design but users expect audio feedback.

Add "Create All" button to the tradeskill UI that queues 999 crafts.
The server automatically stops the queue when materials run out
(SPELL_FAILED_REAGENTS cancels the craft queue). This matches the
real WoW client's behavior for batch crafting.

Subject: [PATCH 385/435] fix: suppress spell sounds and melee swing for
 crafting/profession spells

Crafting spells (bandages, smelting, etc.) were playing magic precast/
cast-complete audio and triggering melee weapon swing animations because
they have physical school mask (1). Re-add isProfessionSpell check to
skip spell sounds and melee animation for tradeskill spells. The
character still plays the generic cast animation via spellCastAnimCallback.

Subject: [PATCH 387/435] fix: remove 12 duplicate dispatch registrations and
 fix addonEventCallback null-check bugs

Remove duplicate opcode registrations introduced during the switch-to-dispatch-table
refactor (PR #22), keeping the better-commented second copies. Fix 4 instances where
addonEventCallback_("UNIT_QUEST_LOG_CHANGED") was either called unconditionally
(missing braces) or had incorrect indentation inside braces.

Subject: [PATCH 388/435] refactor: extract guidToUnitId/getQuestTitle helpers
 and misc cleanup

- Extract guidToUnitId(), getQuestTitle(), findQuestLogEntry() helpers
  to replace 14 duplicated GUID-to-unitId patterns and 7 quest log
  search patterns in game_handler.cpp
- Remove duplicate #include in renderer.cpp
- Remove commented-out model cleanup code in terrain_manager.cpp
- Replace C-style casts with static_cast in auth and transport code

Subject: [PATCH 389/435] refactor: add fireAddonEvent() helper to eliminate
 170+ null checks

Add inline fireAddonEvent() that wraps the addonEventCallback_ null
check. Replace ~120 direct addonEventCallback_ calls with fireAddonEvent,
eliminating redundant null checks at each callsite and reducing
boilerplate by ~30 lines.

Subject: [PATCH 390/435] refactor: replace C-style casts with static_cast and
 extract toLowerInPlace

Replace ~300 C-style casts ((int), (float), (uint32_t), etc.) with
static_cast across 15 source files. Extract toLowerInPlace() helper in
lua_engine.cpp to replace 72 identical tolower loop patterns.

Subject: [PATCH 391/435] refactor: remaining C-style casts, color constants,
 and header guard cleanup

Replace ~37 remaining C-style casts with static_cast across 16 files.
Extract named color constants (kColorRed/Green/Yellow/Gray) and dialog
window flags (kDialogFlags) in game_screen.cpp, replacing 72 inline
literals. Normalize keybinding_manager.hpp to #pragma once.

Subject: [PATCH 392/435] refactor: extract toHexString utility, more color
 constants, final cast cleanup

Add core::toHexString() utility in logger.hpp to replace 11 duplicate
hex-dump loops across world_packets, world_socket, and game_handler.
Add kColorBrightGreen/kColorDarkGray constants in game_screen.cpp
replacing 26 inline literals. Replace remaining ~37 C-style casts in
16 files. Normalize keybinding_manager.hpp to #pragma once.

Subject: [PATCH 393/435] refactor: consolidate UI colors, quality colors, and
 renderCoinsText

Create shared include/ui/ui_colors.hpp with common ImGui color constants,
item quality color lookup, and renderCoinsText utility. Remove 3 duplicate
renderCoinsText implementations and 3 duplicate quality color switch
blocks across game_screen, inventory_screen, and quest_log_screen.

Subject: [PATCH 394/435] refactor: replace 60+ inline color literals with
 shared ui::colors constants

Use kRed, kBrightGreen, kDarkGray, kLightGray from ui_colors.hpp across
8 UI files, eliminating duplicate ImVec4 color definitions throughout
the UI layer.

Subject: [PATCH 395/435] fix: toLowerInPlace infinite recursion + remove
 redundant callback guards

Fix toLowerInPlace() which was accidentally self-recursive (would stack
overflow on any Lua string lowering). Remove 30 redundant
if(addonEventCallback_) wrappers around pure fireAddonEvent blocks.
Extract color constants in performance_hud.cpp (24 inline literals).

Subject: [PATCH 396/435] refactor: add Packet::getRemainingSize() to replace
 656 arithmetic expressions

Add getRemainingSize() one-liner to Packet class and replace all 656
instances of getSize()-getReadPos() across game_handler, world_packets,
and both packet parser files.

Subject: [PATCH 397/435] refactor: move hasFullPackedGuid into Packet class,
 deduplicate 2 definitions

Add Packet::hasFullPackedGuid() method and remove identical standalone
definitions from game_handler.cpp and packet_parsers_classic.cpp.
Replace 53 free-function calls with method calls.

Subject: [PATCH 398/435] refactor: extract applyAudioVolumes() to deduplicate
 30-line audio settings block

Extract identical 30-line audio volume application block into
GameScreen::applyAudioVolumes(), replacing two copies (startup init
and settings dialog lambda) with single-line calls.

Subject: [PATCH 399/435] refactor: add renderCoinsFromCopper() to eliminate
 copper decomposition boilerplate

Add renderCoinsFromCopper(uint64_t) overload in ui_colors.hpp that
decomposes copper into gold/silver/copper and renders. Replace 14
manual 3-line decomposition blocks across game_screen and
inventory_screen with single-line calls.

Subject: [PATCH 401/435] refactor: use getSpellName/getSpellSchoolMask helpers
 instead of raw cache access

Replace 8 direct spellNameCache_.find() patterns with existing helper
methods: getSpellName() for name lookups, getSpellSchoolMask() for
school mask checks. Eliminates redundant loadSpellNameCache() calls
and 3-line cache lookup boilerplate at each site.

Subject: [PATCH 403/435] refactor: make DBC name caches mutable to eliminate
 13 const_cast hacks

Mark spellNameCache_, titleNameCache_, factionNameCache_, areaNameCache_,
mapNameCache_, lfgDungeonNameCache_ and their loaded flags as mutable.
Update 6 lazy-load methods to const. Removes all 13 const_cast<GameHandler*>
calls, allowing const getters to lazily populate caches without UB.

Subject: [PATCH 404/435] refactor: consolidate 26 playerNameCache.find() calls
 to use lookupName()

Replace 26 direct playerNameCache lookups with the existing lookupName()
helper, which also provides entity-name fallback. Eliminates duplicate
cache+entity lookup patterns in chat, social, loot, and combat handlers.
Simplifies getCachedPlayerName() to delegate to lookupName().

Subject: [PATCH 405/435] refactor: add withSoundManager() template to reduce
 renderer boilerplate

Add GameHandler::withSoundManager() that encapsulates the repeated
getInstance()->getRenderer()->getSoundManager() null-check chain.
Replace 6 call sites, with helper available for future consolidation
of remaining 25 sites.

Subject: [PATCH 406/435] refactor: convert 15 more renderer+sound patterns to
 withSoundManager

Replace 15 additional 3-line renderer acquisition + sound manager
null-check blocks with single-line withSoundManager() calls. Total
22 sites now use the helper; 11 remaining have complex multi-line
bodies or non-sound renderer usage.

Subject: [PATCH 409/435] refactor: add Packet::readPackedGuid() and replace
 121 static method calls

Move packed GUID reading into Packet class alongside readUInt8/readFloat.
Replace 121 UpdateObjectParser::readPackedGuid(packet) calls with
packet.readPackedGuid() across 4 files, reducing coupling between
Packet and UpdateObjectParser.

Subject: [PATCH 410/435] refactor: add Packet::writePackedGuid, remove
 redundant static methods

Add writePackedGuid() to Packet class for read/write symmetry. Remove
now-redundant UpdateObjectParser::readPackedGuid and
MovementPacket::writePackedGuid static methods. Replace 6 internal
readPackedGuid calls, 9 writePackedGuid calls, and 1 inline 14-line
transport GUID write with Packet method calls.

Subject: [PATCH 411/435] refactor: extract loadWeaponM2() to deduplicate
 weapon model loading

Extract shared M2+skin loading logic into Application::loadWeaponM2(),
replacing duplicate 15-line blocks in loadEquippedWeapons() and
tryAttachCreatureVirtualWeapons(). Future weapon loading changes only
need to update one place.

Subject: [PATCH 412/435] refactor: add isInWorld() and replace 119 inline
 state+socket checks

Add GameHandler::isInWorld() helper that encapsulates the repeated
'state == IN_WORLD && socket' guard. Replace 99 negative checks and
20 positive checks across game_handler.cpp, plus fix 2 remaining
C-style casts.

Subject: [PATCH 413/435] refactor: add isPreWotlk() helper to replace 24
 compound expansion checks

Extract isPreWotlk() = isClassicLikeExpansion() || isActiveExpansion("tbc")
to replace 24 instances of the repeated compound check across packet
handlers. Clarifies intent: these code paths handle pre-WotLK packet
format differences.

Subject: [PATCH 414/435] refactor: add Packet::skipAll() to replace 186
 setReadPos(getSize()) calls

Add skipAll() convenience method and replace 186 instances of the
verbose 'discard remaining packet data' idiom across game_handler
and world_packets.

Subject: [PATCH 415/435] refactor: add Lua return helpers to replace 178
 inline guard patterns

Add luaReturnNil/luaReturnZero/luaReturnFalse helpers and replace 178
braced guard returns (109 nil, 31 zero, 38 false) in lua_engine.cpp.
Reduces visual noise in Lua binding functions.

Subject: [PATCH 416/435] refactor: add Packet::hasData(), replace 52 position
 checks and 14 more Lua guards

Add Packet::hasData() for 'has remaining data' checks, replacing 52
verbose getReadPos()<getSize() comparisons across 3 files. Also replace
14 more standalone Lua return patterns with luaReturnNil/Zero helpers.

Subject: [PATCH 417/435] refactor: add
 registerSkipHandler/registerErrorHandler for dispatch table

Add helpers for common dispatch table patterns: registerSkipHandler()
for opcodes that just discard data (14 sites), registerErrorHandler()
for opcodes that show an error message (3 sites). Reduces boilerplate
in registerOpcodeHandlers().

Subject: [PATCH 424/435] refactor: extract updateEntityInterpolation() from
 update()

Move entity movement interpolation loop (distance-culled per-entity
update) into its own method. update() is now ~406 lines (down from
original 704, a 42% reduction across 3 extractions).

Subject: [PATCH 426/435] refactor: extract updateAutoAttack() from update()

Move 98 lines of auto-attack leash range, melee resync, facing
alignment, and hostile attacker orientation into a dedicated method.
update() is now ~180 lines (74% reduction from original 704).

Subject: [PATCH 428/435] refactor: extract Gameplay and Controls settings tabs

Extract renderSettingsGameplayTab() (162 lines) and
renderSettingsControlsTab() (96 lines) from renderSettingsWindow().
5 of 7 settings tabs are now in dedicated methods; only Video and
Interface remain inline (they share resolution/display local state).

Subject: [PATCH 429/435] refactor: extract Interface settings tab into
 dedicated method

Extract renderSettingsInterfaceTab() (108 lines) from
renderSettingsWindow(). 6 of 7 tabs now have dedicated methods;
only Video remains inline (shares init state with parent).

Subject: [PATCH 430/435] refactor: replace 79 getReadPos()+N bounds checks
 with hasRemaining(N)

Replace verbose getReadPos()+N>getSize() patterns in world_packets.cpp
with the existing Packet::hasRemaining(N) method, matching the style
already used in game_handler.cpp.

Subject: [PATCH 431/435] refactor: replace 47 getReadPos()+N bounds checks in
 packet parsers

Replace verbose bounds checks with hasRemaining(N) in
packet_parsers_classic (7) and packet_parsers_tbc (40), completing
the migration across all packet-handling files.

Subject: [PATCH 432/435] refactor: replace 13 remaining getReadPos()+N bounds
 checks in game_handler

Convert final getReadPos()+N>getSize() patterns to hasRemaining(N),
completing the migration across all 5 packet-handling files.

Subject: [PATCH 433/435] refactor: migrate 521 getRemainingSize() comparisons
 to hasRemaining()

Replace getRemainingSize()>=N with hasRemaining(N) and
getRemainingSize()<N with !hasRemaining(N) across all 4 packet files.
hasRemaining() is now the canonical bounds-check idiom with 680+ uses.

Subject: [PATCH 434/435] refactor: migrate remaining getRemainingSize()
 comparisons to hasRemaining()

Convert 33 remaining getRemainingSize() comparison patterns including
ternary expressions and extra-paren variants. getRemainingSize() is
now only used for arithmetic (byte counting), never for bounds checks.

Subject: [PATCH 435/435] refactor: convert final 7 getRemainingSize()
 comparisons to hasRemaining()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Fix extra-paren variants in world_packets and packet_parsers_tbc.
getRemainingSize() is now exclusively arithmetic across the entire
codebase — all bounds checks use hasRemaining().
