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.
