writePath static method

void writePath(String path, String pathValue)

Writes the PATH entry of path's profile to pathValue, preserving any other env entries and surrounding comments. Creates the file (and its parent directory) from a template when it does not yet exist.

Implementation

static void writePath(String path, String pathValue) {
  final file = File(path);
  final existing = file.existsSync() ? file.readAsStringSync() : '';

  if (existing.trim().isEmpty) {
    file.parent.createSync(recursive: true);
    file.writeAsStringSync(_template(pathValue));
    return;
  }

  final doc = loadYaml(existing);
  if (doc is Map && doc['env'] is Map) {
    final editor = YamlEditor(existing)..update(['env', 'PATH'], pathValue);
    file.writeAsStringSync(editor.toString());
  } else if (doc is Map) {
    final editor = YamlEditor(existing)..update(['env'], {'PATH': pathValue});
    file.writeAsStringSync(editor.toString());
  } else {
    // Root is not a mapping (unexpected); replace with a fresh template.
    file.writeAsStringSync(_template(pathValue));
  }
}
