How to use golang to implement setLuaPath ？

[chushuai]

int setLuaPath( lua_State* L, const char* path )
{
lua_getglobal( L, "package" );
lua_getfield( L, -1, "path" ); // get field "path" from table at top of stack (-1)
std::string cur_path = lua_tostring( L, -1 ); // grab path string from top of stack
cur_path.append( ";" ); // do your path magic here
cur_path.append( path );
lua_pop( L, 1 ); // get rid of the string on the stack we just pushed on line 5
lua_pushstring( L, cur_path.c_str() ); // push the new one
lua_setfield( L, -2, "path" ); // set the field "path" in table at -2 with value at top of stack
lua_pop( L, 1 ); // get rid of package table from top of stack
return 0; // all done!
}

You can pretty much 1-on-1 swap out the C functions with Go functions.

• L.GetGlobal(...)
• L.GetField(...)
• L.ToString(...)
• L.Pop(...)
• L.PushString(...)
• L.SetField(...)
• L.Pop(...)
