rvben/rumdl v0.0.167

on GitHub

Added

• Configuration validation with fuzzy-match suggestions

  • Comprehensive unknown key detection for .rumdl.toml and pyproject.toml
  • Intelligent "did you mean?" suggestions using Levenshtein distance algorithm
  • File path context in validation warnings for easy debugging
  • Catches typos in global options, rule names, and rule options
  • Example: line-lenght → suggests line-length, reflw → suggests reflow
  • Zero-dependency implementation with configurable similarity threshold
  • Helps users catch configuration mistakes before they cause confusion

• MD053: Support for community comment-style references

  • Recognizes and ignores reference-style link syntax used as comments
  • Supports widely-used patterns: [//]: # (comment), [comment]: #, [note]: #, [todo]: #, [fixme]: #, [hack]: #
  • Any reference with just # as URL is treated as a comment
  • While not in CommonMark/GFM specs, used across 23+ markdown implementations
  • Complements HTML comments with a less HTML-like syntax option
  • Improves compatibility with existing markdown practices

• MD013: line-length = 0 to disable all line length checks

  • Setting line-length = 0 now completely disables MD013 rule
  • Provides explicit way to turn off line length validation entirely
  • More intuitive than previous workarounds
  • Useful when line length management is handled by other tools or not desired

• MD051: mdbook template support

  • Added detection and slug generation for mdbook templates
  • Recognizes {{#template path/to/file.md}} syntax
  • Properly generates GitHub-compatible slugs for template-included headings
  • Improves compatibility with mdbook documentation projects

• LSP: Manual "Reflow paragraph" code action for MD013 warnings

  • New code action available for MD013 line length warnings when auto-reflow is disabled
  • Allows users to manually reflow specific paragraphs without enabling global reflow in config
  • Appears as "Reflow paragraph" in Quick Fix menu (not marked as preferred, so won't trigger on save)
  • Intelligently detects paragraph boundaries and reflows entire paragraph, not just the flagged line
  • Respects line length limit from warning message or defaults to 80 characters
  • Provides a way to try paragraph reflow before committing to enabling it globally
  • Gives users fine-grained control over which paragraphs to reflow

Fixed

• LSP: Preserve trailing newline in reflow action

  • Manual reflow code action now correctly preserves trailing newlines
  • Prevents unwanted file modifications from reflow operations
  • Maintains document structure integrity

• LSP: Improve logging and resolve auto-fix issues

  • Enhanced LSP server logging for better debugging
  • Resolved various auto-fix edge cases and reliability issues

• MD051: Correct GitHub slug generation for angle brackets

  • Fixed incorrect slug generation for headings containing angle brackets
  • Now properly handles special characters in anchor generation
  • Improves accuracy of link validation for complex headings

Changed

• MD033: Remove unhelpful message suffix

  • Simplified warning messages for inline HTML detection
  • Removed redundant information to reduce noise
  • Cleaner, more focused error messages

• Code cleanup: Remove dead code

  • Removed unused LinkImageStyle enum from MD054
  • General refactoring to improve maintainability
  • Fixed clippy warnings

Documentation

• MD033: Document mdbook use case for semantic HTML
  • Added documentation about using semantic HTML in mdbook projects
  • Clarifies when and why inline HTML might be intentionally used
  • Helps users understand legitimate use cases for HTML in markdown
