discoverCommandsInDir function

List<DiscoveredCommand> discoverCommandsInDir(Directory commandsDir)

Scans commandsDir for *.dart files (excluding _index.g.dart and anything else starting with _), extracts ArtisanCommand subclass names, returns one DiscoveredCommand per match.

Multiple matching classes in the same file are returned in declaration order. The result is sorted by file name to keep the generated index deterministic across runs.

Implementation

List<DiscoveredCommand> discoverCommandsInDir(Directory commandsDir) {
  if (!commandsDir.existsSync()) return const <DiscoveredCommand>[];

  final entries = commandsDir.listSync().whereType<File>().where((f) {
    final base = p.basename(f.path);
    if (!base.endsWith('.dart')) return false;
    if (base.startsWith('_')) return false; // _index.g.dart + any private file
    return true;
  }).toList()
    ..sort((a, b) => a.path.compareTo(b.path));

  final out = <DiscoveredCommand>[];
  for (final file in entries) {
    final source = file.readAsStringSync();
    for (final match in _classPattern.allMatches(source)) {
      final className = match.group(1)!;
      out.add(
        DiscoveredCommand(
          className: className,
          fileName: p.basename(file.path),
        ),
      );
    }
  }
  return out;
