How to use golang to implement setLuaPath ?
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.
