rpmcrab

A drop-in replacement for rpmlint (2.10.0, openSUSE flavour, checks: 43), rewritten in Rust.

rpmcrab runs identically to rpmlint: same command-line flags, same TOML configuration, same rpmlintrc filters, and the same frozen output and exit-code contract that external tooling (OBS build summaries, openQA, the openSUSE badness-999 gate) already consumes. It is not a bug-for-bug port: upstream false positives and never-firing checks are fixed, and every fix is recorded in a machine-enforced ledger. Behavioural divergence is deferred to a later major version.

• The compatibility contract — what is frozen and what may diverge — lives in docs/DESIGN.md.
• The roadmap lives in the milestones and the umbrella RFC issue; the spec lives in docs/DESIGN.md, never the reverse.

Pre-1.0. The crate layout and the report-rendering pipeline land first (M1); byte-identical output is proven against a synthetic check set before any real check exists. See the milestones for sequencing.

Requires a stable Rust toolchain (see rust-toolchain.toml), plus the RPM development headers (rpm-devel on openSUSE, librpm-dev on Debian/Ubuntu — pkg-config must find rpm.pc). The default build enables librpm's build feature for spec parsing, whose bindgen step also needs popt.h: add popt-devel (openSUSE) / libpopt-dev (Debian/Ubuntu); on Debian/Ubuntu librpm-dev already pulls popt in.

The local gate (fmt, clippy, tests, cargo-deny, layering) is:
