Detailed Description

Lua state manager.

Each Lua object manages one lua_State. If debugEnable at the constructor is true, full debug hook will be enabled. This may be heavy. If debugEnable is false, debug hook mask is only instruction count. instLimit is a feature for preventing infinite loop. LuaDebugger set it as hook count, and if COUNT event would happened, hook function raises an lua error.

Constructor & Destructor Documentation

yappy::lua::Lua::Lua	(	bool	debugEnable,
		size_t	maxHeapSize,
		size_t	initHeapSize = 1024 * 1024,
		int	instLimit = 10 * 10000
	)

Create new lua_State and open standard libs.

Parameters

[in]	debugEnable	Enable debug feature.
[in]	maxHeapSize	Max memory usage. (only virtual address range will be reserved at first)
[in]	initHeapSize	Initial commit size. (physical memory mapped)
[in]	instLimit	Lua bytecode instruction count limit. (no limit if 0)

yappy::lua::Lua::~Lua

(

)

Destruct lua_State.

Member Function Documentation

template<class ParamFunc = doNothing, class RetFunc = doNothing>

void yappy::lua::Lua::callGlobal ( const char *  funcName, bool  autoBreak, ParamFunc  pushArgFunc = doNothing(), int  narg = 0, RetFunc  getRetFunc = doNothing(), int  nret = 0  )

inline

Calls global function.

pushParamFunc and getRetFunc must be able to be called by:

pushParamFunc(lua_State *);
getRetFunc(lua_State *);

(lambda expr is recommended)

[](lua_State *L) {
    lua_pushXXX(L, ...);
}

Parameters

[in]	funcName	Function name.
[in]	autoBreak	Break by debugger at the first LINE event if true.
[in]	pushArgFunc	Will be called just before lua_pcall().
[in]	narg	Arguments count.
[in]	getRetFunc	Will be called just after lua_pcall().
[in]	nret	Return values count.

lua_State * yappy::lua::Lua::getLuaState

(

)

const

Returns lua_State which this object has.

Returns

lua_State

Definition at line 139 of file script.cpp.

void yappy::lua::Lua::loadFile	(	const wchar_t *	fileName,
		bool	autoBreak,
		bool	prot = true
	)

Load script file and eval it.

Parameters

[in]	fileName	Script file name.
[in]	autoBreak	Debug break at the first line.
[in]	prot	Use pcall() if true. (false is include from Lua only)
