ls method

@override List<String> ls([ String? path ])

List all files in current (or specified) directory. Maps to: ls

Returns list of names (directories end with /).

Implementation

@override
List<String> ls([String? path]) {
  final targetPath = path != null ? _state.resolvePath(path) : _state.cwd;
  final dir = Directory(targetPath);

  if (!dir.existsSync()) {
    throw DirectoryNotFoundException(targetPath);
  }

  final entries = dir.listSync();
  final result = <String>[];

  for (final entry in entries) {
    // Use path.split to get the name since uri.pathSegments.last
    // returns empty string for directories
    final segments = entry.path.split('/');
    final name = segments.last.isEmpty && segments.length > 1
        ? segments[segments.length - 2]
        : segments.last;
    if (entry is Directory) {
      result.add('$name/');
    } else {
      result.add(name);
    }
  }

  return result..sort();
