## [0.1.21] - 2026-02-14 ### Added - **CLI**: New `full` output format with ruff-style source line display showing offending lines with caret underlines ([#425](rvben/rumdl#425)) - **GitHub Action**: Add generic `args` input for passing extra CLI flags like `--output-format json` ([#406](rvben/rumdl#406)) - **MD060**: `loose-last-column` now caps last column width at header text width — body cells shorter than header are padded, longer cells extend beyond ([#424](rvben/rumdl#424)) ### Changed - **CLI**: `--output-format` help text now documents all available formats with descriptions ([#425](rvben/rumdl#425)) ### Fixed - **CI**: SchemaStore sync workflow now formats schema with Prettier before committing ## [0.1.20] - 2026-02-13 ### Added - **Config**: Add `extends` key for config file inheritance — config files can declare a base config to inherit from, with child settings merging on top. Supports relative paths, absolute paths, `~/` expansion, recursive chains (up to 10 levels), and circular reference detection. Works in both `.rumdl.toml` and `pyproject.toml` ([#390](rvben/rumdl#390)) - **Code block tools**: Detect fenced code blocks inside MkDocs admonitions and tab containers ([#423](rvben/rumdl#423)) ### Fixed - **MD013**: Detect mkdocstrings autodoc blocks regardless of flavor setting ([#396](rvben/rumdl#396)) - **MD013**: Enforce strict line-length limit in semantic-line-breaks merge ([#414](rvben/rumdl#414)) - **MD060**: Detect misaligned content in center/right-aligned table columns ([#426](rvben/rumdl#426)) ### Changed - **Config**: `disable` now uses replace semantics (matching Ruff's `ignore`), giving `extend-disable` a distinct purpose as the additive variant that survives CLI overrides. Document the rule selection model with `extend-enable` / `extend-disable` in global settings ## [0.1.19] - 2026-02-13 ### Added - **Kramdown flavor**: Add kramdown/Jekyll markdown flavor support with block IAL (`{:.class}`, `{:#id}`), span IAL, and extension block (`{::comment}`, `{::nomarkdown}`, `{::options}`) detection. Enable with `flavor = "kramdown"` or `flavor = "jekyll"`. MD041 skips IALs and extension blocks as preamble; MD051 defaults to kramdown anchor style - **Config**: Add `extend-enable` and `extend-disable` global config keys for additive rule activation, following Ruff's extend-select pattern. Five rules are now opt-in by default: MD060, MD063, MD072, MD073, MD074. Use `extend-enable = ["MD060"]` to enable individual opt-in rules without overriding the full `enable` list ### Fixed - **MD013**: Prevent reflow from splitting autolinks (`<https://...>`) at the colon in URL schemes by treating them as atomic elements ([#416](rvben/rumdl#416), [#417](rvben/rumdl#417)) - **MD013**: Prevent reflow from splitting inside markdown link text, code spans, and HTML tag attributes by tracking element byte spans during word-wrap fallback ([#412](rvben/rumdl#412), [#413](rvben/rumdl#413)) - **MD013**: Thread `length-mode` (chars/visual/bytes) through all reflow length calculations so CJK and other wide characters are measured correctly ([#414](rvben/rumdl#414)) - **MD013**: Abbreviations like `e.g.` and `i.e.` inside parentheses no longer trigger false sentence boundary detection in `sentence-per-line` mode ([#422](rvben/rumdl#422)) - **MkDocs**: Track fenced code blocks inside admonitions to prevent false `in_code_block` overrides that caused reflow corruption ([#415](rvben/rumdl#415)) - **MD060**: Fix table formatter idempotency bug where ATX headings containing pipe characters were misidentified as table rows and reformatted - **Kramdown**: Fix self-closing extension blocks (`{::options ... /}`) incorrectly disabling linting for all subsequent lines - **Kramdown**: Fix extension fence leakage causing MD022 false positives ### Changed - **Kramdown**: Add three-layer architectural filtering for extension blocks (LineInfo sanitization, collection filtering, warning pipeline safety net) so rules automatically skip kramdown extension blocks without per-rule opt-in ## [0.1.18] - 2026-02-10 ### Added - **Config**: `enable = ["ALL"]` keyword to explicitly enable all rules (equivalent to omitting `enable`), with `disable` still applied on top - **MD013**: In non-strict mode, suppress line-length warnings when the excess comes entirely from inline link/image URLs — if replacing `[text](url)` with `[text]` would bring the line within the limit, the warning is not raised ([#393](rvben/rumdl#393)) - **MD057**: `compact-paths` config option to warn about unnecessary path traversal in wiki links (e.g., `../sibling` when `sibling` suffices) ([#391](rvben/rumdl#391)) ### Changed - **Config**: `enable = []` now means "no rules enabled" (was incorrectly treated as "use defaults"). Omitting `enable` still enables all rules. Use `enable = ["ALL"]` to explicitly enable all rules. ### Fixed - **MD013**: Skip mkdocstrings autodoc blocks (`::: module.Class` with indented YAML options) during paragraph reflow ([#396](rvben/rumdl#396)) - **MD013**: Implement trailing-word replacement for non-strict mode — reflow now correctly handles lines where the last word pushes past the limit - **MD044**: Skip proper name checking when link text is itself a URL (starts with `http://`, `https://`, or `www.`), matching markdownlint behavior ([#395](rvben/rumdl#395)) ## [0.1.17] - 2026-02-09 ### Fixed - **Config**: `enable = []` is now correctly treated as "use defaults" (all rules enabled) instead of acting as an empty allowlist that disabled all rules - **MD013**: Preserve MkDocs admonition markers (`!!!`, `???`, `???+`) during text reflow instead of stripping them from continuation lines - **MD033**: Escape regex special characters in `allowed-elements` config values — square brackets and other metacharacters were being interpreted as regex patterns - **MD036**: Only flag emphasis as heading-like when it forms a standalone paragraph (surrounded by blank lines), matching markdownlint behavior ### Changed - **MD045**: Made diagnostic-only — auto-fix removed because meaningful alt text requires human judgment. Automated placeholders derived from filenames (e.g., "User Profile image") are harmful for accessibility. The rule now reports missing alt text without offering to fix it. - **CI**: Pass version in pre-commit dispatch payload ## [0.1.16] - 2026-02-09 ### Added - **MD013**: `semantic-line-breaks` reflow mode (preview) — breaks lines at semantic boundaries using a cascading strategy: sentence boundaries first, then clause punctuation (`,` `;` `:` `—`), then English break-words (`and`, `or`, `but`, `which`, `that`, `because`, etc.), then word wrap as fallback ([#388](rvben/rumdl#388)) ### Fixed - **MD013**: Fix panic on multi-byte characters (smart quotes, em dashes) in semantic line break sentence boundary detection - **MD013**: Preserve element adjacency during reflow — text directly adjacent to shortcodes, code spans, or links (e.g., `v{{< shortcode >}}`) is no longer split across lines - **MD013**: Use actual line length instead of URL-stripped length for line-length checks — lines were incorrectly passing when long URLs inflated the real length - **MD013**: Preserve Quarto/Pandoc div markers (`::: {.class}`) during text reflow instead of reflowing them into surrounding paragraphs - **MD001**: Track fixed heading level in `check()` for idempotent fixes — repeated `--fix` runs no longer produce different output for multi-level heading violations - **MD032**: Idempotent fix for ordered non-1 list followed by unordered list - **MD032**: Use `fix()` method in proptest and allow convergence within 3 passes - **MD062**: Bail out when unmatched angle bracket masks closing paren, preventing false positive warnings on valid link syntax - **MD009**: Strip all trailing Unicode whitespace in a single pass instead of handling each whitespace character separately - **GitHub Action**: Support multiple space-separated file paths in `path` input - **docs**: Fix YAML typo, indentation, and `--no-exclude` descriptions (thanks @JonathanWillitts in [#385](rvben/rumdl#385)) - **config**: Handle markdownlint `default` key and boolean rule semantics in `.markdownlint.json` compatibility ([#389](rvben/rumdl#389)) ### Changed - **reflow**: Extract block boundary helpers to deduplicate paragraph detection logic - **MD001**: Extract `compute_heading_fix()` to unify check() and fix() code paths - **docs**: Add Helix editor formatter configuration and note about built-in support - **docs**: Add link and nav validation guide, fix MD051 cross-file documentation
