Hello everyone !
I'm new at Lua. So far I've compiled Lua 4.1a as
Shared Lib (dll) on W2k and initalized. To interface
Lua with the GUI Lua-IO has to be redirected. The
code below works so far. An Alert Box pops up
with the Test Message but is immediatly followed by
another one: "unable to recover; exiting" obviously
comming from luaD_breakrun(). What's wrong here ?
Well, I didn't dig very deep into the docs up to
now so please excuse if I've missed something
obvious.
regards
Peter

lua_state lua;
int luaErrorHandler(lua_State state){
char* msg = lua_tostring(state,1);
/* pop up an Alert Box */
return 0;
}
void luaInitialize(void){
lua = lua_newthread(NULL,0); /* test omitted */
/* open lua libs */
lua_baselibopen (lua);
lua_iolibopen(lua);
lua_strlibopen(lua);
lua_mathlibopen(lua);
lua_dblibopen"(lua);
/* redirect io handler */
lua_register(lua,"_ALERT",luaErrorHandler);
lua_register(lua,"_OUTPUT",luaOutputHandler);
lua_register(lua,"_INPUT",luaInputHandler);
/* test */
lua_error("TEST ERROR");
}
