W36 – Retranslate specific pieces, down to a single key

You can now retranslate specific pieces of your content, down to a single key.

The Lingo.dev CLI command lingo push retranslates only the source text you edited. But some changes happen in your localization engine, not your files: you switch the model, add glossary terms, or edit your rules. Your source stays identical, so lingo push finds nothing to redo. Now you can retranslate the exact pieces you want, from a single key to a whole language.

Run lingo push messages/en.json --key auth.login and Lingo.dev retranslates only the keys you list. A key is its path in the file, so you can pick one value, a whole subtree, or several keys at once. Everything else stays the same. If you are not sure which keys to list, your AI coding assistant can read the file and write the command for you.

If a change affects more than a few strings, retranslate whole files. Run lingo push src/en/**/*.json --force and Lingo.dev retranslates every string in the files you list. And if one language needs redoing, run lingo purge --locale fr to delete the French files, then lingo push --backfill-missing to translate them again. Your other languages stay the same.

The retranslation guide covers every option.

You can do the same in a pull request. Comment /lingo translate docs/en/**/*.md --force and the GitHub App retranslates the matching files in the PR. Add --locales fr to redo just one language.
