#### Lua support
To profile Lua code using tracy, include the `tracy/TracyLua.hpp` header file in your Lua wrapper and execute `tracy::LuaRegister( lua_State* )` function to add instrumentation support. In your Lua code, add `tracy.ZoneBegin()` and `tracy.ZoneEnd()` calls to mark execution zones. Double check if you have included all return paths!
To profile Lua code using tracy, include the `tracy/TracyLua.hpp` header file in your Lua wrapper and execute `tracy::LuaRegister( lua_State* )` function to add instrumentation support. In your Lua code, add `tracy.ZoneBegin()` and `tracy.ZoneEnd()` calls to mark execution zones. Double check if you have included all return paths! Use `tracy.Message( text )` to send messages.
Even if tracy is disabled, you still have to pay the no-op function call cost. To prevent that you may want to use the `tracy::LuaRemove( char* script )` function, which will replace instrumentation calls with whitespace. This function does nothing if profiler is enabled.
