ferrocat-po

Performance-first Gettext PO parsing, serialization, merge helpers, and high-level catalog workflows for ferrocat.

Add it with:

cargo add ferrocat-po

This crate covers both the low-level Gettext PO surface and the higher-level catalog layer.

At the catalog layer, it 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 this crate when you want that surface directly:

• parse_po / parse_po_borrowed for raw Gettext PO parsing
• stringify_po for Gettext PO serialization
• merge_catalog for lightweight gettext-style merges
• parse_catalog, update_catalog, and NormalizedParsedCatalog::compile for higher-level catalog workflows across Gettext PO and NDJSON storage
• compile_catalog_artifact for requested-locale runtime artifacts with fallback resolution and missing reports
• compile_catalog_artifact_selected for selected compiled-ID subsets of those runtime artifacts

parse_po_borrowed keeps many fields as references into the input buffer, so it currently accepts LF-only content. If your source can contain CRLF or bare CR line endings, normalize it before calling parse_po_borrowed or use the owned parse_po parser.

If you want the umbrella dependency instead, use ferrocat.
