Action Summary

Summary: rumdl is a high-performance Rust-based Markdown linter and formatter that offers 81 lint rules covering common Markdown issues, automatic formatting with --fix, zero dependencies, and multiple installation options (Rust, Python, standalone binaries). It is designed for speed, with benchmarks showing significant performance improvements over alternatives.

What’s Changed

Security

• config: keep an extends target’s path and contents out of messages about it (72bcb49)

  An extends value is expanded from the environment before it is resolved, so naming the resolved path in an error or warning printed environment variable values wherever that message went, which under CI is the build log. extends also points at an arbitrary path, so a target that is not valid TOML had its offending line quoted back. A file reached through extends is now named by the reference as written, and its own text is never repeated. A config you name yourself is unchanged, and rumdl config, the language server’s report to its editor, and RUST_LOG=debug still show resolved paths.
