lua_pushboolean Print() issues 5.2.2

[Michael Stephens <engrstephens@...>]

Hi all,

I'm new to embedding LUA and am loving it. I had a small issue I'm trying to resolve. It seems if I call pushboolean from C and then catch that value on the other side and print it it breaks. It is probably something I'm doing stupidly. Any help would be awesome!

Output:

a

5

b

test

c

Script:

a, b , c = test()

print("a")

print(a)

print("b")

print(b)

print("c")

print(c) --fails on this call

C Code:

extern "C" {

#include "lua.h"

#include "lualib.h"

#include "lauxlib.h"

#include "lobject.h"

}

#define lua_register(L,n,f) (lua_pushcfunction(L, (f)), lua_setglobal(L, (n)))

static int print(lua_State* L);

static int test(lua_State* L);

static const struct luaL_Reg mylib [] = {

  {"print", print},

  {"test", test},

  {NULL, NULL} /* end of array */

};

static int test(lua_State* L)

{

lua_pushinteger(L,5);

lua_pushfstring(L,"test");

lua_pushboolean(L,1);

return 3;

}

static int print(lua_State* L)

{

int nargs = lua_gettop(L);

for (int i=1; i <= nargs; ++i) {

printf( lua_tostring(L, i));

    }

    printf("\r\n");

return 0;

}

int main()

{

    lua_State *l = luaL_newstate();

luaL_openlibs(l);

lua_getglobal(l, "_G");

luaL_setfuncs(l, mylib, 0);

lua_pop(l, 1);

if(luaL_loadfile(l,"D:\\Michael\\Desktop\\lua\\Debug\\test.lua")==0)

{

lua_pcall(l,0,0,0);

}

else

{

printf("Failed to run script: %s\n", lua_tostring(l, -1));

}

    lua_close(l);

    return 0;

}
