Release Notes

rvben/rumdl

v0.3.0

Compare Source

Changed

• 2.4–4.7× faster rumdl fmt than 0.2.79 on frozen documentation
  snapshots: Cargo (99 files) 4.7×, MkDocs Material (85 files) 2.6×, and
  Ruff (16 files) 2.4×. Reusing parsed Markdown and shared source analysis
  reduces repeated work. Speedups compare median elapsed times from 31 paired
  runs after five warmups on Apple M6: ordinary Rust 1.96.0 release builds,
  default threads, warm filesystem cache, and --no-config --no-cache --silent
  (--flavor=standard for Cargo/Ruff, --flavor=mkdocs for MkDocs Material).
  Output includes the correctness fixes listed below and can differ from 0.2.79.
• Code block tools are supported and remain opt-in. Missing tags, missing
  active-mode tools and invocations with no tools checked are ignored by default.
  An omitted unknown-tag policy inherits on-missing-language-definition,
  preserving existing strict configurations. Valid internal cached checks count
  as checked; applicable external tools rerun to reflect changes in their own
  configuration and environment.
• on-missing-language-definition = "warn" now reports uncovered languages;
  previous releases treated it as ignore.
• Executable lookup remains system-only by default. Per-binary preferences can
  opt into nearest-first project lookup bounded by repository/configuration
  boundaries, including hoisted workspace installations.
• MD037 still reports spaces inside emphasis delimiters but no longer provides
  automatic fixes, including editor fixes. Repair the reported emphasis manually;
  inserting escapes or removing whitespace can change literal Markdown meaning.

Added

• fmt --preflight and check --fix --preflight validate and plan the complete
  selected file batch before applying any writes, with atomic replacement per
  file after successful planning.
• Configurable coverage policies with block diagnostics and invocation-wide
  fail-fast behavior. Invalid tool definitions receive central configuration
  warnings, made fatal by --deny-config-warnings.
• Fail-fast tool policies report an incomplete invocation (exit 2), including
  when document finding failures are disabled with --fail-on never.
• Shared full-table language recognition and flavor-aware fence coverage.
  No-tools invocation errors preserve JSON's findings array and use SARIF
  invocation notifications rather than assigning errors to a document.
• --stdin-batch-targets FILE supplies a NUL-delimited file/directory inventory
  for cross-file existence checks without requiring placeholder documents.
• MD013: add reflow-break-code-spans to keep code spans whole while emphasis wraps (bd41ee8)
• fmt: add Bun code-block formatting and reduce redundant checks (2605ead)
• stdin: accept separate batch link target inventories (56c492b)

Fixed

• Headings inside blockquotes and list items are checked and fixed relative to
  their container. Heading spacing, indentation, capitalization, and reflow
  preserve list markers and avoid rewriting literal text or template code.
• Tables nested under multiple containers are recognized. Blank-line checks
  respect MkDocs admonition openers and Markdown-enabled HTML boundaries;
  HTML markers inside comments and indented code remain literal content.
• MD035: leave a first-line thematic break unchanged when fixing it would
  turn the following content into front matter.
• File discovery skips source-code files matched by broad include patterns,
  while explicitly supplied unsupported source files still receive an error.
• Windows path matching handles device-prefixed paths and directory separators
  consistently across discovery and per-file configuration.
• Reject invalid UTF-8 in external tool stdout instead of replacing invalid
  bytes and allowing that output to become formatted document content.
