xlog function

void xlog(dynamic msg)

给外部调用快速定位log所在位置

Implementation

void xlog(dynamic msg) {
  if (!kDebugMode) {
    debugPrint('$msg');
    return;
  }
  final now = DateTime.now().toString();
  final time = now.substring(5, now.length > 23 ? 23 : now.length);
  String loc = '';
  final root = Directory.current.path.replaceAll('\\', '/');
  try {
    final lines = StackTrace.current.toString().split('\n');
    if (lines.length > 1) {
      // 先尝试将 package 路径归一化为 file 绝对路径；如果是 file 路径则保持不变
      final line = lines[1].replaceFirst(
        RegExp(r'\(package:[^/]+/'),
        '(file:///$root/lib/',
      );
      final m = RegExp(r'\(file:///(.+?)\)').firstMatch(line);
      if (m != null) loc = ' ${m.group(1)}';
    }
  } catch (_) {}
  debugPrint('\x1B[90m[$time]\x1B[0m\x1B[94m$loc\x1B[0m $msg');
}
