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)
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.
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.
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.
