runSafely function

Future<void> runSafely(List<String> args, bool doNotExit, FutureOr<void> action(Stopwatch, Options))

Run the given action in a safe try/catch block, allowing Dartle to handle any errors by logging the appropriate build failure.

If doNotExit is true, then this method will not call exit on build completion, re-throwing Exceptions. Otherwise, the process will exit with 0 on success, or the appropriate error code on error.

Implementation

Future<void> runSafely(List<String> args, bool doNotExit,
    FutureOr<void> Function(Stopwatch, Options) action) async {
  final stopWatch = Stopwatch()..start();
  var options = const Options();

  try {
    options = parseOptions(args);
    await action(stopWatch, options);
    if (!doNotExit) abort(0);
  } on DartleException catch (e) {
    // activate SEVERE logging in case logging was not enabled yet
    activateLogging(log.Level.SEVERE);
    logger.severe(e.message);
    if (logger.isLoggable(log.Level.FINE)) {
      _logStackTrace(e);
    }
    if (options.logBuildTime) {
      logger.severe(ColoredLogMessage(
          '✗ Build failed in ${elapsedTime(stopWatch)}', LogColor.red));
    }
    if (doNotExit) {
      rethrow;
    } else {
      abort(e.exitCode);
    }
  } on Exception catch (e, st) {
    // activate SEVERE logging in case logging was not enabled yet
    activateLogging(log.Level.SEVERE);
    logger.severe('Unexpected error', e, st);
    if (options.logBuildTime) {
      logger.severe(ColoredLogMessage(
          '✗ Build failed in ${elapsedTime(stopWatch)}', LogColor.red));
    }
    if (doNotExit) {
      rethrow;
    } else {
      abort(22);
    }
  }
