Release notes

Added

• Config: Implement Ruff-style config inheritance model

  • User config (~/.config/rumdl/) now serves as base, project config extends it
  • Project-level enable/disable are additive to user config by default
  • Clear precedence: CLI flags > project config > user config > defaults

• MD001: Recognize frontmatter title as implicit H1

  • Documents with title: in YAML frontmatter no longer require an H1 heading
  • Aligns with common static site generator behavior (Jekyll, Hugo, etc.)

Fixed

• MD057/MD051: Skip wikilinks in cross-file validation (fixes #235)

  • Wikilinks ([[page]]) were incorrectly triggering “relative link does not exist” warnings
  • Wikilinks use a different linking system (Obsidian, etc.) and should not be validated as file paths

• MD057: Fix LSP diagnostic position for cross-file links (fixes #234)

  • LSP was pointing to link text [...] instead of URL (...)
  • Now correctly highlights the URL portion in editor diagnostics

• MD012: Remove all trailing blank lines at EOF

  • Previously only removed one trailing blank line per fix pass
  • Now removes all consecutive trailing blank lines in a single fix

• Config: Add missing aliases for MD062/MD064/MD065 rules (fixes #232)

  • Added kebab-case aliases for newer rules
  • Fixed MD069 typo in alias registration

• CLI: Fail fast when --config conflicts with --no-config/--isolated

  • These flags are contradictory and now produce a clear error instead of silently ignoring one

• Cross-file validation: Fix duplicate warnings for same link

  • MD051 and MD057 both contribute links to the workspace index with different column positions
  • Deduplication now ignores column differences, preventing duplicate warnings
