Development

Adding a New Language

The app uses a lightweight dictionary-based i18n system (Audiomatic/Strings.cs). English and French are included out of the box. To add a new language:

1. Add translations in Strings.cs — append your language code to each entry in the Translations dictionary:

   ["Library"] = new() { ["en"] = "Library", ["fr"] = "Bibliothèque", ["de"] = "Bibliothek" },

2. Add the language option in MainWindow.xaml.cs — find the // Language section block inside ShowSettingsFlyout() and add a line:

   AddLanguageOption("de", Strings.T("German"));

3. Add the language name translations in Strings.cs so it displays correctly in every language:

   ["German"] = new() { ["en"] = "German", ["fr"] = "Allemand", ["de"] = "Deutsch" },

The fallback chain is: requested language → English → raw key. Missing translations for a given key will gracefully fall back to English.
