loadLanguages static method

void loadLanguages(String innoPath)

Loads the supported languages for the given Inno Setup executable path.

Scans the installation directory containing innoPath for Default.isl (English) and every Languages/*.isl file, and replaces the previously cached set. This is the only way to populate all.

Implementation

static void loadLanguages(String innoPath) {
  final innoDir = File(innoPath).parent;
  final languagesDir = Directory(p.join(innoDir.path, "Languages"));
  final languages = <Language>[];

  // for English, the default language.
  if (File(p.join(innoDir.path, "Default.isl")).existsSync()) {
    languages.add(Language._("English", "Default.isl"));
  }
  // rest of the languages are in the Languages directory.
  if (languagesDir.existsSync()) {
    languagesDir
        .listSync()
        .where((file) => file is File && file.path.endsWith(".isl"))
        .forEach((file) {
      final fileName = p.basename(file.path);
      final fileStem = p.basenameWithoutExtension(fileName);
      languages.add(Language._(fileStem, "Languages\\${fileName}"));
    });
  }
  _cachedLangs = languages;
}
