Action Summary

rumdl is a high-performance Markdown linter and formatter built with Rust to ensure consistency, best practices, and improved developer experience when working with Markdown files. It automates tasks like detecting issues, applying formatting, and fixing violations, while offering configurable rules, support for multiple Markdown flavors, and compatibility with CI/CD workflows. Designed for speed, it provides fast linting and intelligent caching, making it ideal for large projects or editor integrations.

Release notes

Fixed

• MkDocs: Support multi-line code spans inside MkDocs containers (admonitions, content tabs, markdown HTML) — pulldown-cmark missed these because it treats 4-space-indented container content as indented code blocks. Replaced the per-line backtick scanner with a dedent-and-reparse approach that handles all CommonMark edge cases including nested containers (#487, reported by @stefanvanburen)
• MD034: Fix code span filter to use byte offsets instead of single-line column checks, preventing false positives for URLs and emails inside multi-line code spans
• MD052: Fix code span filter to use byte offsets, preventing false positives for reference links inside multi-line code spans
