Action Summary

rumdl is a high-performance Markdown linter and formatter built with Rust, designed to ensure consistency and best practices in Markdown files. It automates the detection and correction of common Markdown issues with 57 lint rules, supports multiple Markdown flavors, and provides a fast, configurable, and dependency-free tool suitable for both local development and CI/CD workflows. Its speed and user-friendly CLI make it an efficient alternative to other Markdown linting tools.

Release notes

Added

• CLI: Add --fixable and --unfixable flags to control which rules are allowed to auto-fix. --fixable acts as an allowlist (only listed rules can fix), --unfixable acts as a blocklist (takes precedence). Both accept comma-separated rule names or aliases (#472)

Fixed

• CLI: Resolve rule name aliases in fixable/unfixable config lists so that aliases like commands-show-output correctly match canonical names like MD014
• Rules: Detect links and images inside MkDocs admonitions, content tabs, and markdown HTML blocks
• Docs: Fix incorrect MD014 documentation that claimed the rule cannot be auto-fixed — it removes $ prompts from commands without output, matching markdownlint-cli behavior (#473)

Changed

• Docs: Add feature comparison matrix and cold start benchmarks for all 8 comparison tools
