Create domain-specific .pot template files: + - `priv/gettext/auth.pot` + - `priv/gettext/equipment.pot` + - `priv/gettext/admin.pot` + - `priv/gettext/emails.pot` + - Keep existing `default.pot` and `errors.pot` + +2.

Create `lib/towerops_web/gettext_helpers.ex` + +4. Update `lib/towerops_web.ex` to import helpers in `html_helpers/0` + +5. Create Mix task to auto-populate English translations (msgstr = msgid) + +### Phase 2: Module-by-Module Migration + +**Order of migration (smallest to largest):** + +1. **Emails** (`lib/towerops/accounts/user_notifier.ex`) + - Self-contained, minimal dependencies + - Domain: `emails` + +2. **Auth Flows** + - `lib/towerops_web/controllers/user_*_html.ex` + - `lib/towerops_web/live/user_settings_live/` + - Domain: `auth` + +3. **Core Components** (`lib/towerops_web/components/`) + - `core_components.ex` - Generic labels + - `layouts.ex` - Navigation, user menu + - Domain: `default` + +4. **Equipment Features** + - `lib/towerops_web/live/device_live/` + - `lib/towerops_web/live/equipment_live/` + - `lib/towerops_web/live/alert_live/` + - Domain: `equipment` + +5. **Admin Features** + - `lib/towerops_web/live/admin/` + - Domain: `admin` + +6. **Error Messages** + - Review all `put_flash(:error, ...)` calls + - Ecto validation messages + - Domain: `errors` + +**Per-module process:** + +1. Update module to use gettext calls +2. Run `mix gettext.extract --merge` +3. Run `mix populate_english` to fill English translations +4. Compile and verify no errors +5. Manual QA - check pages render correctly +6. Run `mix test` to verify no regressions +7. Commit changes for that module + +### Phase 3: Verification + +1. Run `mix gettext.extract --check-up-to-date` (fails if untranslated strings) +2. Add to CI pipeline to catch missing translations +3. Visual QA pass on all major pages +4. Test all flash messages, error states, email previews + +## Gettext Commands Reference + +```bash +# Extract new strings from code +mix gettext.extract + +# Merge extracted strings into existing .po files (preserves translations) +mix gettext.merge priv/gettext + +# Extract and merge in one step +mix gettext.extract --merge + +# Check for unused translations (fail if out of date) +mix gettext.extract --check-up-to-date +``` + +## Testing Strategy + +1. **Unit Tests:** Continue to work unchanged (test behavior, not strings) +2. **Integration Tests:** May need updates if asserting on specific text +3. **CI Check:** Add `mix gettext.extract --check-up-to-date` to CI pipeline +4. **Manual QA:** Visual inspection of key pages after migration +5. **Email Preview:** Use Swoosh mailbox (`/dev/mailbox`) to verify email translations + +## Future Enhancements + +### Adding New Languages + +When ready to add a new language (e.g., Spanish): + +1. Create `priv/gettext/es/LC_MESSAGES/*.po` files +2. Copy structure from English .po files +3. Replace msgstr values with Spanish translations +4. Recompile application +5. Set user locale via session/cookie + +### Locale Selection + +Add user preference for language: + +1. Add `locale` field to users table (default: "en") +2. Set `Gettext.put_locale/1` in authentication pipeline +3. Add language selector in user settings +4. Persist choice in session/database + +### Dynamic Content + +For database-stored content that needs translation: + +1. Consider using a translation table pattern +2. Or use JSONB columns with locale keys +3.
