Adds two scripts to help maintainers fill in missing .po translations
using Claude AI, and applies them to backfill all 184 missing Spanish strings.
New scripts:
- scripts/translations/build_translation_index.py — reads every .po file
and outputs a cross-language JSON index {msgid: {lang: translation}}
used to provide reference context to the AI
- scripts/translations/backfill_po.py — for a target language, finds all
untranslated entries, batches them, and calls claude -p with cross-language
context to generate draft translations marked #, fuzzy for human review
Design highlights:
- Cross-language translations are passed per-string so the AI can disambiguate
ambiguous English (e.g. "Scale", "Table") from how other translators handled it
- --min-context N skips strings with fewer than N reference translations
- Each generated entry is tagged with a translator comment listing the model
and which languages provided context (e.g. [refs: fr, ru])
- translation_index.json added to .gitignore (regenerated locally)
Spanish translations:
- Backfilled all 184 previously untranslated strings in es/LC_MESSAGES/messages.po
- All entries marked #, fuzzy pending human review
Docs: added "Backfilling missing translations with AI" section to
docs/developer_docs/contributing/howtos.md
npm shortcuts added to superset-frontend/package.json:
- translations:build-index
- translations:backfill
