languages (langs)

Lists built-in language catalog entries used by generate and locale-source validation hints.

i18nprune languages
i18nprune langs --filter ja
i18nprune languages --json

languages --json returns catalog rows in the standard envelope with code, english, native, and direction. Useful jq patterns:

# Find RTL languages quickly
i18nprune languages --json | jq '.data[] | select(.direction == "rtl") | {code, english, native}'

# Count matches for a filter
i18nprune languages --filter ar --json | jq '.data | length'

Catalog source is generated into packages/core/src/shared/languages/catalog/languages.json via pnpm generate:languages.
