rvben/rumdl v0.1.15

on GitHub

Added

• MD057: relative-to-docs option - New config option for validating absolute
  link paths relative to a documentation root directory

Performance

• 2.5x faster on real-world repositories - Comprehensive performance audit and
  optimization across the core pipeline, rule implementations, and infrastructure.
  Validated against ripgrep, ruff, and rust repositories (1,832 files, 276K lines)
  with zero regressions.

  Key optimizations:

  • Switch release profile from size optimization (opt-level = "z") to speed (opt-level = 3)
  • Zero-allocation line ending normalization for LF-only files (common case)
  • Replace chars().nth() O(n) calls with O(1) byte indexing for ASCII checks
  • Promote MD034 regex patterns to LazyLock statics (eliminated ~160K mutex cycles per 10K-line file)
  • Reduce LineInfo memory 79% by boxing rare struct variants (3.4MB → 720KB for 10K-line files)
  • Eliminate redundant Vec<char> allocation in horizontal rule detection
  • Cache debug environment variable lookups in list parser
  • Move ListBlock by value instead of cloning
  • Fix MD044 O(n×m) boundary checks and full-document regex scans
  • Fix MD052 repeated full-document HTML comment scans
  • Replace per-line HashMap cloning in InlineConfig with state-transition storage
  • Deduplicate content.lines().collect() across 48 call sites in 27 rules
  • Compute content lines once in LintContext, share via ctx.raw_lines()
  • Unify code block detection into a single pass shared with LineIndex
  • Eliminate redundant InlineConfig parsing (parse once in LintContext)
  • Deduplicate line offset and front matter computation during context construction
  • Add O(1) line access via pre-computed line starts in LineIndex
  • Lazy-initialize rule registry with LazyLock (eliminated 5+ redundant all_rules() calls)
  • Remove unused mmap code path from file reading

Changed

• explain command completeness - Now uses the full rule registry instead of
  a manually maintained list, ensuring all rules (including MD069-MD074) are included
