parse method

Future<void> parse(List<String> arguments)

Parse the arguments list populating properties on the SmartArg class.

If Parser.exitOnFailure is set to true, this function will call exit(1) if there is a command line parsing error. It will do so only after telling the user what the error was and displaying the result of usage().

Implementation

Future<void> parse(List<String> arguments) async {
  _resetParser();

  try {
    final ParsedResult result = _parse(arguments);
    if (isNotNull(result.command)) {
      await _launchCommand(result.command!, result.commandArguments ?? []);
    } else if (result.success) {
      _validate();
    }
  } on ArgumentError catch (e) {
    if (isTrue(_app?.exitOnFailure)) {
      print(e.toString());
      print('');
      print(usage());
      exit(1);
    }

    rethrow;
  }
}
