Re: #define with lua

[Ivan Kolev <ikolev@...>]

I use a macro to export C constants to Lua like this:

#define lua_setConst(name) { lua_pushnumber( name ); lua_setglobal(
#name ); }

Then for each C library I have a Lua initialization function which
registers all need C functions and constants with Lua like this:

int LibInitLua() {
	// ... export C functions

	// export C constants
	lua_setConst( RED_DOOR );
	return 1;
};

static int libInit = LibInitLua();

Then I can use RED_DOOR in Lua just as in C.

Regards,
Ivan
