translify add-missing

Formerly translify sync — the old name still works but is deprecated.

Add keys used in code but missing from your JSON translation files.

Usage

translify add-missing
translify add-missing --dry-run
translify add-missing --empty

What it does

1. Extracts all translation keys from source code (namespace-aware — see namespace_functions for useTranslations/ getTranslations support)
2. Loads all translation files matching translations.files
3. For each language file, adds keys that are missing
4. By default, copies the value from the default language for non-default locales
5. Writes updated files to disk surgically — only the newly inserted keys show up in the diff. Existing indentation, key order, and spacing are left untouched (no more full-file reformats on large files)

Example output

✓ Added 12 keys across 3 files

▸ Results
  en       messages/en.json    +8 added
  fr       messages/fr.json    +12 added
  de       messages/de.json    up to date

Options

Option	Description
--empty	Add missing keys with empty values instead of copying
--dry-run	Preview what would change without writing
-c, --config	Path to config file

Safe to run repeatedly

add-missing only ever adds keys — it never removes them. You can run it any time without fear of losing existing translations. Use translify check-unused to review keys that may be safe to remove.
