ferrocat 0.9.0

Rust-first gettext and ICU toolkit for PO parsing, catalog updates, and MessageFormat parsing.
Documentation

ferrocat

crates.io docs.rs

Public umbrella crate for the ferrocat workspace.

Add it with:

cargo add ferrocat

It re-exports the stable Rust API from ferrocat-po and ferrocat-icu.

At the catalog layer, ferrocat supports three explicit modes:

  • classic Gettext catalog mode: Gettext PO + gettext-compatible plurals
  • ICU-native Gettext PO mode: Gettext PO + ICU MessageFormat
  • ICU-native NDJSON catalog mode: NDJSON catalog storage + ICU MessageFormat

NDJSON + gettext-compatible plurals is intentionally unsupported.

Use it when you want one dependency for:

  • Gettext PO parsing and serialization
  • catalog normalization, updating, runtime compilation, and requested-locale artifact generation
  • ICU MessageFormat parsing and inspection
