rvben/rumdl v0.0.209

on GitHub

Added

• MD070: Nested code fence collision detection (new rule)
  • Detects when inner code fences would prematurely close outer fences
  • Example: outer ``` containing inner ``` causes collision
  • Suggests using longer fences (````) for outer blocks
  • Configurable languages option to limit checking to specific info strings (default: ["", "markdown", "md"])
  • Auto-fix increases fence length to prevent collisions

Fixed

• MD040: Fix false positives on list-indented code blocks (fixes #257)

  • Refactored to use pulldown-cmark for CommonMark-compliant code block detection
  • List-indented closing fences no longer incorrectly flagged as missing language
  • Eliminates manual fence state tracking that failed for consecutive code blocks

• CLI: Support respect-gitignore in config files (fixes #258)

  • Added respect-gitignore option to [global] section in .rumdl.toml and pyproject.toml
  • CLI flag --respect-gitignore=false syntax now works (previously only --no-respect-gitignore)

• Release: Fix pre-built aarch64-linux binaries for 16K page systems (fixes #256)

  • Pre-built binaries for aarch64-unknown-linux-gnu and aarch64-unknown-linux-musl now work on Asahi Linux and Raspberry Pi 5
  • Set JEMALLOC_SYS_WITH_LG_PAGE=16 to configure jemalloc for 64K page compatibility
  • Previously crashed with "Unsupported system page size" on systems with 16K or 64K pages

• List detection: Filter out YAML/TOML lists in frontmatter

  • Frontmatter arrays like tags: [foo, bar] no longer incorrectly detected as markdown lists
  • Fixes false positives in MD004, MD005, MD007, MD030, and other list-related rules

• List detection: Handle nested list items and tab indentation

  • Nested items where content begins on the next line are now correctly parsed
  • Tab-indented nested lists now properly detected and validated

• MD030: Eliminate false positives on hard-wrapped citations and continuations (fixes #253)

  • Replaced manual regex-based list detection with pulldown-cmark parser for context-aware list item detection
  • Hard-wrapped citation continuations like (Doe 2003, p.\n 1234) no longer trigger false positives
  • Resolves LSP formatting infinite loop (adding trailing space → MD009 → removing space → MD030)
  • Added 16 comprehensive edge case tests covering citations, blockquoted lists, URLs, ISBNs, and mathematical expressions

• Heading detection: Prevent list items from being detected as setext headings (fixes #254)

  • Per CommonMark spec 4.3, setext heading content cannot be a list item, ATX heading, blockquote, thematic break, code fence, or HTML block
  • Incomplete list items (e.g., - Orange followed by -) no longer incorrectly detected as level 2 headings
  • Eliminates false positives in all heading-related rules (MD041, MD022, MD023, MD024, MD025, MD026, MD003, MD043)
  • Added comprehensive validation for all CommonMark setext heading exclusions

• Output formatters: Correct severity field in JSON, JSON Lines, and Azure Pipelines formats

  • Fixed bug where severity was always output as "error" regardless of actual severity level
  • JSON/JSON Lines/Azure formatters now correctly output "error", "warning", or "info" based on actual severity
