runCommand method

FutureOr<int> runCommand(List<UndoableCommand> commands)

Runs a list of contiguous UndoableCommand and return an exit code If one command throws an Exception they will all be undone by calling the undo Function in UndoableCommand

Implementation

FutureOr<int> runCommand(List<UndoableCommand> commands) async {
  debugPrintToConsole(message: "Executing ${commands.length} commands");

  int i = 0;
  try {
    while (i < commands.length) {

      debugPrintToConsole(
        message: "Executing $i: ${c.runtimeType}",
      );
      await c.execute();
    }
    return 0;
  } catch (e, trace) {
    if (!isVerboseMode) {
      printToConsole(
        message: "An error has occurred. Run with -${CliCommandOptionsEnum.verbose.abbreviation} to see more details",
        color: CliColor.red,
      );
    }

    if (e is FileSystemException) {
      onFileSystemException(e);
    } else {
