โšก Executive Summary (TL;DR)

Biome @biomejs/[email protected]. Source highlight: Fixed a regression in Astro frontmatter parsing where comments inside quoted strings were incorrectly detected as actual comments. This caused the parser to prematurely terminate frontmatter parsing when encountering strings like `const test = "//";`.

โœจ New Features & Capabilities (4)

  • feat(lint): implement `noContinue`
  • chore: add graphite as bronze sponsor
  • refactor(formatter): introduce Token element
  • feat: support html.experimentalFullSupportEnabled for vue with jsx/tsx script

๐Ÿ”ง Bug Fixes & Patches (6)

  • Fixed a regression in Astro frontmatter parsing where comments inside quoted strings were incorrectly detected as actual comments. This caused the parser to prematurely terminate frontmatter parsing when encountering strings like `const test = "//";`.
  • Refactored formatter to use strict `Token` element for better performance. The new `Token` variant is optimized for static, ASCII-only text (keywords, operators, punctuation) with the following constraints:
  • ASCII only (no Unicode characters)
  • No newlines (`\n`, `\r`)
  • No tab characters (`\t`)
  • Fixed #7943. Rules' `options` are now properly merged with the inherited `options` from a shared configuration.

## 2.3.4 ### Patch Changes - [#7989](https://github.com/biomejs/biome/pull/7989) [`4855c4a`](https://github.com/biomejs/biome/commit/4855c4a5c28d8381dd724449d43a9a60a860edaa) Thanks [@alissonlauffer](https://github.com/alissonlauffer)! - Fixed a regression in Astro frontmatter parsing where comments inside quoted strings were incorrectly detected as actual comments. This caused the parser to prematurely terminate frontmatter parsing when encountering strings like `const test = "//";`. For example, the following Astro frontmatter now parses correctly: ```astro --- const test = "// not a real comment"; --- ``` - [#7968](https://github.com/biomejs/biome/pull/7968) [`0b28f5f`](https://github.com/biomejs/biome/commit/0b28f5f47aa968bd2511224679ae1cfbcf708fd7) Thanks [@denbezrukov](https://github.com/denbezrukov)! - Refactored formatter to use strict `Token` element for better performance. The new `Token` variant is optimized for static, ASCII-only text (keywords, operators, punctuation) with the following constraints: - ASCII only (no Unicode characters) - No newlines (`\n`, `\r`) - No tab characters (`\t`) This enables faster printing and fitting logic by using bulk string operations (`push_str`, `len()`) instead of character-by-character iteration with Unicode width calculations. - [#7941](https://github.com/biomejs/biome/pull/7941) [`19b8280`](https://github.com/biomejs/biome/commit/19b82805e013d5befc644f85f272df19ed1264ae) Thanks [@Conaclos](https://github.com/Conaclos)! - Fixed [#7943](https://github.com/biomejs/biome/issues/7943). Rules' `options` are now properly merged with the inherited `options` from a shared configuration. This means that you can now override a specific option from a rule without resetting the other options to their default. Given the following shared configuration: ```json { "linter": { "rules": { "style": { "useNamingConvention": { "level": "on", "options": { "strictCase": false, "conventions": [ { "selector": { "kind": "variable", "scope": "global" }, "formats": ["CONSTANT_CASE"] } ] } } } } } } ``` And the user configuration that extends this shared configuration: ```json { "extends": ["shared.json"], "linter": { "rules": { "style": { "useNamingConvention": { "level": "on", "options": { "strictCase": true } } } } } } ``` The obtained merged configuration is now as follows: ```json { "extends": ["shared.json"], "linter": { "rules": { "style": { "useNamingConvention": { "level": "on", "options": { "strictCase": true, "conventions": [ { "selector": { "kind": "variable", "scope": "global" }, "formats": ["CONSTANT_CASE"] } ] } } } } } } ``` - [#7969](https://github.com/biomejs/biome/pull/7969) [`425963d`](https://github.com/biomejs/biome/commit/425963d636620d852547322f3f029df2ca05318c) Thanks [@ematipico](https://github.com/ematipico)! - Added support for the Svelte syntax `{@debug}`. The Biome HTML parser is now able to parse and format the blocks: ```diff -{@debug foo,bar, something} +{@debug foo, bar, something} ``` - [#7986](https://github.com/biomejs/biome/pull/7986) [`3256f82`](https://github.com/biomejs/biome/commit/3256f824a15dedf6ac23485cdef2bbc92bfc7fd9) Thanks [@lisiur](https://github.com/lisiur)! - Fixed [#7981](https://github.com/biomejs/biome/issues/7981). Now Biome correctly detects and parses `lang='tsx'` and `lang='jsx'` languages when used inside in `.vue` files, when `.experimentalFullSupportEnabled` is enabled. - [#7921](https://github.com/biomejs/biome/pull/7921) [`547c2da`](https://github.com/biomejs/biome/commit/547c2da02590832d4941f017541142c17d1734a9) Thanks [@dyc3](https://github.com/dyc3)! - Fixed [#7854](https://github.com/biomejs/biome/issues/7854): The CSS parser, with `tailwindDirectives` enabled, will now parse `@source inline("underline");`. - [#7856](https://github.com/biomejs/biome/pull/7856) [`c9e20c3`](https://github.com/biomejs/biome/commit/c9e20c3780b328ff59b63fa8917938d97b090148) Thanks [@Netail](https://github.com/Netail)! - Added the nursery rule [`noContinue`](https://biomejs.dev/linter/rules/no-continue/). Disallowing the usage of the `continue` statement, structured control flow statements such as `if` should be used instead. **Invalid:** ```js let sum = 0, i; for (i = 0; i < 10; i++) { if (i >= 5) { continue; } sum += i; } ``` **Valid:** ```js let sum = 0, i; for (i = 0; i < 10; i++) { if (i < 5) { sum += i; } } ``` ## What's Changed * fix(parse/css): parse tailwind `@source inline(...)` by @dyc3 in https://github.com/biomejs/biome/pull/7921 * feat(html): implement `{@debug}` parsing by @ematipico in https://github.com/biomejs/biome/pull/7969 * fix(parse/tailwind): fix lexing variants that start with numbers by @dyc3 in https://github.com/biomejs/biome/pull/7966 * feat(lint): implement `noContinue` by @Netail in https://github.com/biomejs/biome/pull/7856 * fix(config): implement Merge for rules' options by @Conaclos in https://github.com/biomejs/biome/pull/7941 * chore: add graphite as bronze sponsor by @dyc3 in https://github.com/biomejs/biome/pull/7974 * chore: graphql tests options by @Netail in https://github.com/biomejs/biome/pull/7979 * refactor(formatter): introduce Token element by @denbezrukov in https://github.com/biomejs/biome/pull/7968 * fix(ROME_CHANGELOG.md): grammar and typo error by @WuMingDao in https://github.com/biomejs/biome/pull/7992 * chore(parser): increase size of SyntaxKindSet bitfield by @ryan-m-walker in https://github.com/biomejs/biome/pull/7994 * fix(RELEASES.md): grammar and typo error by @WuMingDao in https://github.com/biomejs/biome/pull/7993 * fix(html): fix comment detection in Astro frontmatter by @alissonlauffer in https://github.com/biomejs/biome/pull/7989 * feat: support html.experimentalFullSupportEnabled for vue with jsx/tsx script by @lisiur in https://github.com/biomejs/biome/pull/7986 * ci: release by @github-actions[bot] in https://github.com/biomejs/biome/pull/7965 ## New Contributors * @WuMingDao made their first contribution in https://github.com/biomejs/biome/pull/7992 * @lisiur made their first contribution in https://github.com/biomejs/biome/pull/7986 **Full Changelog**: https://github.com/biomejs/biome/compare/@biomejs/[email protected]...@biomejs/[email protected]
