rvben/rumdl v0.0.200

on GitHub

Added

• CLI: Add --no-defaults flag to rumdl config command (fixes #218)

  • Show only non-default configuration values, excluding defaults
  • Useful for seeing only customizations without the noise of default values
  • Works with both smart output (with provenance annotations) and --output toml/json formats
  • Mutually exclusive with --defaults flag
  • Displays helpful message when all configurations are using defaults
  • Supports filtering of global config, rule configs, and per-file-ignores

• SARIF: Map severity field to SARIF result levels

  • Error severity maps to SARIF "error" level
  • Warning severity maps to SARIF "warning" level
  • Improves integration with tools that consume SARIF output

• Testing: Add O(n²) complexity regression testing infrastructure

  • Detect potential quadratic time complexity issues in rules
  • Prevent performance regressions in line analysis algorithms

Fixed

• MD051 (link-fragments): Support extension-less cross-file links (GitHub-style) (fixes extension-less link validation)

  • Recognize extension-less paths with fragments as cross-file links (e.g., [link](page#section) → page.md#section)
  • Resolve extension-less paths by trying markdown extensions (.md, .markdown, .mdx, etc.)
  • Handles GitHub-style links that omit file extensions, matching GitHub's rendering behavior
  • Applied to both link detection and cross-file validation
  • Reduces false positives in repositories using extension-less links

• MD054 (link-image-style): Fix false positives for task lists and HTML tags (fixes false positive detection)

  • Skip validation for links/images inside task list items (e.g., - [ ] [link](url))
  • Skip validation for links/images inside HTML tags (e.g., <a href="url">text</a>)
  • Reduces false positives when links are part of task lists or HTML structures

• MD057 (link-target-exists): Skip email addresses and fix absolute path bug (fixes email and path handling)

  • Skip validation for email addresses (e.g., mailto:user@example.com)
  • Fix bug where absolute paths were incorrectly validated
  • Improves accuracy by correctly identifying email links vs file links

• MD063 (heading-capitalization): Respect lowercase-words when inline code/link is last segment (fixes #223)

  • When the last word in a heading is inline code or a link, respect lowercase-words configuration
  • Previously, inline code/link at the end was not checked against lowercase-words list
  • Ensures consistent capitalization rules apply to all heading segments

• MD007 (ul-indent): Fix indent=1 edge case and integrate edge case tests (fixes edge cases)

  • Fix handling of indent = 1 configuration edge cases
  • Integrate comprehensive edge case tests for better coverage
  • Improves reliability for non-standard indent configurations

• MD057 (link-target-exists): Point diagnostics to URL instead of link text (fixes #226)

  • LSP diagnostics now point to the actual non-existent URL rather than the link text
  • Fixes incorrect positioning in editors where diagnostics appeared at wrong location
  • Makes diagnostics semantically correct by highlighting the actual problem
  • Improves both CLI and LSP diagnostic accuracy

• File processor: Canonicalize file paths to prevent duplicate warnings

  • Normalize file paths to resolve symbolic links and relative paths
  • Prevents duplicate warnings when the same file is referenced via different paths
  • Improves accuracy when processing files via symlinks or relative paths

• Rules: Fixes for issues 219 and 220 (fixes #219, #220)

  • Fixes addressing edge cases and false positives
  • Improves overall rule accuracy and reliability

Performance

• MD007 (ul-indent): Cache mixed list nesting detection and optimize blank line checks
  • Cache results of mixed list nesting detection to avoid redundant calculations
  • Optimize blank line checks for better performance on large files
  • Reduces processing time for files with complex list structures

Changed

• Rules: Categorize severities by document impact

  • Reorganized rule severities into meaningful categories
  • Structure-critical rules (MD001, MD002, MD003, etc.) remain Error
  • Style-preference rules (MD004, MD007, MD029, etc.) now Warning
  • Better alignment between severity and actual impact on document quality

• Documentation: Add severity categorization section to RULES.md

  • Documents the reasoning behind severity assignments
  • Explains the distinction between structural errors and style warnings
  • Helps users understand why rules have their assigned severity levels

• Tests: Reorganize issue-specific tests into appropriate test files

  • Moved Issue #210 tests to tests/rules/md007_test.rs
  • Moved Issue #209 tests to tests/rules/md007_test.rs
  • Moved Issue #197 tests to tests/cli_integration_tests.rs
  • Removed issueXXX-named test files per project conventions
