mf2-build

The MessageFormat 2 build pipeline: from a directory of message resources, per language, to what an application ships — the manifest, one binary catalog per locale, and a generated Rust module with the application's tr! macro. It checks every message and reports what a translation is missing or gets wrong.

The build script of the crate that includes the generated module — the application, or a translation crate several share — runs it, and reads the features of that crate's mf2 dependency through links:

fn main() {
    mf2_build::run();
}

The mf2 command (mf2-cli) creates such a crate (mf2 init) and runs the same checks from the command line.

API documentation: https://docs.rs/mf2-build.

The Rust MF2 book is the user guide.

Versions: every Rust MF2 crate is released together, and 1.x keeps the promise the book's versioning chapter states; the minimum Rust version is 1.88.
