Localization

PRECC renders its status line and short feedback strings in 28 languages. Translations are compiled into the binary, so language selection costs no extra I/O at hook time.

Setting the language

Set the PRECC_LANG environment variable to a supported language code. This wins over every other source.

$ PRECC_LANG=zh precc savings
$ export PRECC_LANG=ja

Persisting via consent.toml

Add [ui] preferred_language = "ja" (or any supported code) to ~/.config/precc/consent.toml to keep the choice across shells without exporting an env var.

# ~/.config/precc/consent.toml
[ui]
preferred_language = "ja"

Resolution order

PRECC checks PRECC_LANG first, then [ui] preferred_language in consent.toml, then falls back to English. The first non-empty signal wins and is cached for the lifetime of the process.

1. PRECC_LANG          (environment variable)
2. consent.toml        ([ui] preferred_language)
3. "en"                (default)

Coverage

28 language columns ship in the translation table. Cells we cannot hand-verify are left empty and fall back to English at lookup time, rather than displaying fabricated script. If you can improve a translation, please send it upstream.

Why it stays fast

Translations are stored as compile-time const arrays inside the precc-core binary, not in SQLite. The hook performs a single in-memory array lookup, so translation costs nothing measurable against the < 5 ms p99 hook budget.
