	Error err = parser.parse(p_script, p_path, false);
	if (err == OK) {
		err = analyzer.analyze();
	}
#ifdef DEBUG_ENABLED
	if (r_warnings) {
		for (const GDScriptWarning &E : parser.get_warnings()) {
			const GDScriptWarning &warn = E;
			ScriptLanguage::Warning w;
			w.start_line = warn.start_line;
			w.end_line = warn.end_line;
			w.leftmost_column = warn.leftmost_column;
			w.rightmost_column = warn.rightmost_column;
			w.code = (int)warn.code;
			w.string_code = GDScriptWarning::get_name_from_code(warn.code);
			w.message = warn.get_message();
			r_warnings->push_back(w);
		}
	}
#endif
	if (err) {
		if (r_errors) {
