localize

name: localize description: Localize ryOS apps and components by extracting hardcoded strings, replacing with translation keys, and syncing across languages. Use when localizing an app, adding i18n support, translating UI text, or working with translation files.

Localize App or Component

Workflow Checklist

- [ ] 1. Extract hardcoded strings
- [ ] 2. Replace with t() calls in source files
- [ ] 3. Add English translations to en/translation.json
- [ ] 4. Sync translations across languages
- [ ] 5. Machine translate [TODO] keys
- [ ] 6. Validate coverage

Step 1: Extract Hardcoded Strings

bun run scripts/extract-strings.ts --pattern [PATTERN]

Step 2: Replace Strings with t() Calls

For each component:

1. Add import: import { useTranslation } from "react-i18next";
2. Add hook: const { t } = useTranslation();
3. Replace strings: t("apps.[appName].category.key")
4. Add t to dependency arrays for useMemo/useCallback

Key Structure

apps.[appName].menu.*        # Menu labels
apps.[appName].dialogs.*     # Dialog titles/descriptions
apps.[appName].status.*      # Status messages
apps.[appName].ariaLabels.*  # Accessibility labels
apps.[appName].help.*        # Help items (auto-translated)

Common Patterns

// Basic
t("apps.ipod.menu.file")

// With variables
t("apps.ipod.status.trackCount", { count: 5 })

// Conditional
isPlaying ? t("pause") : t("play")

// With symbol prefix
`✓ ${t("apps.ipod.menu.shuffle")}`

Step 3: Add English Translations

Add to src/lib/locales/en/translation.json:

{
  "apps": {
    "ipod": {
      "menu": { "file": "File", "addSong": "Add Song..." },
      "dialogs": { "clearLibraryTitle": "Clear Library" },
      "status": { "shuffleOn": "Shuffle ON" }
    }
  }
}

Step 4: Sync Across Languages

bun run scripts/sync-translations.ts --mark-untranslated

Adds missing keys to all language files, marked with [TODO].

Step 5: Machine Translate

bun run scripts/machine-translate.ts

Requires GOOGLE_GENERATIVE_AI_API_KEY env variable.

Step 6: Validate

bun run scripts/find-untranslated-strings.ts

Component Guidelines

Notes

• Emoji/symbols (♪, ✓) can stay hardcoded
• Help items use pattern: apps.[appName].help.[key].title/description
• Include t in dependency arrays when used in useMemo/useCallback
