How to create nested Lua tables using the C API

Question

I want to create a table like

myTable = {
    [0] = { [\"a\"] = 4, [\"b\"] = 2 },
    [1] = { [\"a\"] = 13, [\"b\"] = 37 }
}

using the C AP

Answer 1

For simple code like the one you gave, my lua2c works fine and generates the code below.

/* This C code was generated by lua2c from the Lua code below.

myTable = {
    [0] = { ["a"] = 4, ["b"] = 2 },
    [1] = { ["a"] = 13, ["b"] = 37 }
}
*/
static int MAIN(lua_State *L)
{
 lua_newtable(L);
 lua_pushnumber(L,0);
 lua_newtable(L);
 lua_pushliteral(L,"a");
 lua_pushnumber(L,4);
 lua_pushliteral(L,"b");
 lua_pushnumber(L,2);
 lua_settable(L,-5);
 lua_settable(L,-3);
 lua_pushnumber(L,1);
 lua_newtable(L);
 lua_pushliteral(L,"a");
 lua_pushnumber(L,13);
 lua_pushliteral(L,"b");
 lua_pushnumber(L,37);
 lua_settable(L,-5);
 lua_settable(L,-3);
 lua_settable(L,-5);
 lua_settable(L,-3);
 lua_setglobal(L,"myTable");
 return 0;
}
