Fill iOS localization gaps from .strings → Google Sheets and PR with placeholders (GitHub)
Fill iOS localization gaps from .strings → Google Sheets and PR with placeholders (GitHub) This n8n workflow automatically identifies missing translations in .strings files across iOS localizations (e.g., Base.lproj vs fr.lproj) and generates a report in Google Sheets. Optionally, it creates a GitHub PR to insert placeholder strings ("TODO_TRANSLATE") so builds don't fail. Supports DRY\_RUN mode. Who’s it for iOS teams who want fast feedback on missing translations. Localization managers who want a shared sheet to assign work to translators. How it works A GitHub Webhook triggers on push or pull request. The iOS repo is scanned for .strings files under Base.lproj or en.lproj and their target-language counterparts. It compares keys and identifies what’s missing. A new or existing Google Sheet tab (e.g., fr) is updated with missing entries. If enabled, it creates a GitHub PR with placeholder keys (e.g., "TODO_TRANSLATE"). How to set up Import the Workflow JSON into your n8n instance. Set Config Node values like: { "GITHUB_OWNER": "your-github-user-name", "GITHUB_REPO": "your-iOS-repo-name", "BASE_BRANCH": "develop", "SHEET_ID": "<YOUR_GOOGLE_SHEET_ID>", "ENABLE_PR": "true", "IOS_SOURCE_GLOB": "/Base.lproj/*.strings,/en.lproj/*.strings", "IOS_TARGET_GLOB": "*/.lproj/*.strings", "PLACEHOLDER_VALUE": "TODO_TRANSLATE", "BRANCH_TEMPLATE": "chore/l10n-gap-{{YYYYMMDD}}", } Create GitHub Webhook URL: https://your-n8n-instance/webhook/l10n-gap-ios Content-Type: application/json Trigger on: Push, Pull Request Connect credentials GitHub token with repo scope Google Sheets API (Optional) Slack OAuth + SMTP Requirements | Tool | Needed For | Notes | | ---------------- | -------------------- | ---------------------------------------- | | GitHub Repo | Webhook, API for PRs | repo token or App | | Google Sheets | Sheet output | Needs valid SHEET_ID or create-per-run | | Slack (optional) | Notifications | chat:write scope | | SMTP (optional) | Email fallback | Standard SMTP creds | How to customize Multiple Locales**: Add comma-separated values to TARGET_LANGS_CSV (e.g., fr,de,es). Globs**: Adjust IOS_SOURCE_GLOB and IOS_TARGET_GLOB to scan only certain modules or file patterns. Ignore Rules**: Add IGNORE_KEY_PREFIXES_CSV to skip certain internal/debug strings. Placeholder Value**: Change PLACEHOLDER_VALUE to something meaningful like "@@@". Slack/Email**: Set SLACK_CHANNEL and EMAIL_FALLBACK_TO_CSV appropriately. DRY\_RUN**: Set to true to skip GitHub PR creation but still update the sheet. Add‑ons Android support:** Add a second path for strings.xml (values → values-<lang>), same diff → Sheets → placeholder PR. Multiple languages at once:** Expand TARGET_LANGS_CSV and loop tabs + placeholder commits per locale. .stringsdict handling:** Validate plural/format entries and open a precise PR. Translator DMs:** Provide a LANG → Slack handle/email map to DM translators with their specific file/key counts. GitLab/Bitbucket variants:** Replace GitHub API calls with GitLab/Bitbucket equivalents to open Merge Requests. Use Case Examples Before a test build, ensure fr has all keys present—placeholders keep the app compiling. Weekly run creates a single sheet for translators and a PR with placeholders, avoiding last‑minute breakages. A new screen adds 12 strings; the bot flags and pre‑fills them across locales. Common troubleshooting | Issue | Possible Cause | Solution | | ------------------------ | --------------------------------------------- | ------------------------------------------------------ | | No source files found | Glob doesn't match Base.lproj or en.lproj | Adjust IOS_SOURCE_GLOB | | Target file missing | fr.lproj doesn’t exist yet | Will be created in placeholder PR | | Parsing skips entries | Non-standard string format in file | Ensure proper .strings format "key" = "value"; | | Sheet not updating | SHEET_ID missing or insufficient permission | Add valid ID or allow write access | | PR not created | ENABLE_PR=false or no missing keys | Enable PR and ensure at least one key is missing | | Slack/Email not received | Missing credentials or config | Configure Slack/SMTP properly and set recipient fields | Need Help?
