Patch Changes

• #6908 d77eaff Thanks @ematipico! - Fix #6485: Handle multiple semicolons correctly in blocks (🐛 CSS parser errors on multiple semicolons #6485)

  div {
    box-sizing: border-box;
    color: red;
  }

• #6908 d77eaff Thanks @ematipico! - Fixed #6762, Biome now knows that ~/.config/zed/settings.json and ~/.config/Code/User/settings.json allows comments by default.

• #6908 d77eaff Thanks @ematipico! - Refactor: remove one level of indirection for CSS declarations with semicolon
  Previously, accessing a declaration from a list required an extra step:

  item
  .as_any_css_declaration_with_semicolon()
  .as_css_declaration_with_semicolon()

  Now, it can be done directly with:

  item.as_css_declaration_with_semicolon()

• #6908 d77eaff Thanks @ematipico! - Fixed a bug where the Biome Language Server didn't correctly ignore specific files when vcs.useIgnoreFile is set to true.

• #6908 d77eaff Thanks @ematipico! - Improved the performance of noImportCycles by ~30%.

• #6908 d77eaff Thanks @ematipico! - Fixed #6829: Fixed a false positive reported by useImportExtensions when importing a .js file that had a matching .d.ts file in the same folder.

• #6908 d77eaff Thanks @ematipico! - Fixed an issue where biome was using the wrong string quotes when the classes string has quotes, resulting in invalid code after applying the fix.

• #6908 d77eaff Thanks @ematipico! - Improved #6172: Optimised the way function arguments are stored in Biome's type inference. This led to about 10% performance improvement in RedisCommander.d.ts and about 2% on @next/font type definitions.

• #6908 d77eaff Thanks @ematipico! - Fixed a bug where the Biome Language Server would apply an unsafe fix when using the code action quickfix.biome.

  Now Biome no longer applies an unsafe code fix when using the code action quickfix.biome.

• #6908 d77eaff Thanks @ematipico! - Fixed #6719: The noInvalidUseBeforeDeclaration rule covers additional use cases.

  Examples:

  type Bar = { [BAR]: true };
  const BAR = "bar";

  interface Bar {
    child: { grandChild: { [BAR]: typeof BAR; enumFoo: EnumFoo } };
  }
  const BAR = "bar";
  enum EnumFoo {
    BAR = "bar",
  }

• #6908 d77eaff Thanks @ematipico! - Biome now considers whether the linter is enabled when figuring out how the project should be scanned. Resolves #6815.

• #6908 d77eaff Thanks @ematipico! - Fixed #6165: Fixed false negative in noUnusedPrivateClassMembers rule when checking member usage in classes

• #6908 d77eaff Thanks @ematipico! - Fixed a bug where the root ignore file wasn't correctly loaded during the scanning phase, causing false positives and incorrect expectations among users.

  Now, when using vcs.useIgnoreFile, the the globs specified in the ignore file from the project root will have the same semantics as the files.includes setting of the root configuration.

  Refer to the relative web page to understand how they work.

• #6908 d77eaff Thanks @ematipico! - Fixed #6891: Improved type inference for array indices.

  Example:

  const numbers: number[];
  numbers[42]; // This now infers to `number | undefined`.

• #6908 d77eaff Thanks @ematipico! - Fixed #6796: Fixed a false positive that happened in noFloatingPromises when calling functions that were declared as part of for ... of syntax inside async functions.

  Instead, the variables declared inside for ... of loops are now correctly
  inferred if the expression being iterated evaluates to an Array (support for other iterables will follow later).

  Invalid example

  const txStatements: Array<(tx) => Promise<any>> = [];
  
  db.transaction((tx: any) => {
    for (const stmt of txStatements) {
      // We correctly flag this resolves to a `Promise`:
      stmt(tx);
    }
  });

  Valid example

  async function valid(db) {
    const txStatements: Array<(tx: any) => void> = [(tx) => tx.insert().run()];
  
    db.transaction((tx: any) => {
      for (const stmt of txStatements) {
        // We don't flag a false positive here anymore:
        stmt(tx);
      }
    });
  }

• #6908 d77eaff Thanks @ematipico! - Added the rule noVueReservedProps, resolves #6309.

  It prevents the use of reserved Vue prop names such as key and ref which can cause conflicts and unexpected behavior in Vue components.

  Invalid example

  import { defineComponent } from "vue";
  
  export default defineComponent({
    props: ["ref", "key", "foo"],
  });

  <script setup>
  defineProps({
    ref: String,
    key: String,
    foo: String,
  });
  </script>

  Valid examples

  import { defineComponent } from "vue";
  
  export default defineComponent({
    props: ["foo"],
  });

  <script setup>
  defineProps({ foo: String });
  </script>

• #6912 af7c6c0 Thanks @ematipico! - Fixed #6904. Now Biome correctly applies the argument --assist-enabled=false when running the command ci and the command check.

• #6908 d77eaff Thanks @ematipico! - Allow multiple identifiers in ::part() pseudo-element selector.

  ::part(first second) {
  }

• #6908 d77eaff Thanks @ematipico! - Fixed #6510: The scanner no longer shows diagnostics on inaccessible files unless --verbose is used.

• #6908 d77eaff Thanks @ematipico! - Fixed #6837: Fixed regression with multiple consecutive line suppression comments using instances (like // biome-ignore lint/correctness/useExhaustiveDependencies(depName): reason).

• #6908 d77eaff Thanks @ematipico! - Fixed an issue where textDocument/codeAction in the LSP could respond with outdated text edits after the workspace watcher observed outdated changes to the file.

• #6908 d77eaff Thanks @ematipico! - noFloatingPromises will no longer suggest to add await keyword inside synchronous callbacks nested inside async functions.

• #6908 d77eaff Thanks @ematipico! - Fixed #6777: Fixed type inference handling of this to avoid infinite recursion.

  Thanks to @sterliakov for the thorough investigation!

• #6908 d77eaff Thanks @ematipico! - Fixed #6775: useReadonlyClassProperties now also captures mutations inside function arguments.

  Example:

  class Counter {
    private counter: number;
    count() {
      console.log(this.counter++);
      const counterString = `${this.counter++}`;
    }
  }

• #6723 c434f01 Thanks @sterliakov! - useUniqueElementIds now has an excludedComponents option to support elements using id prop for reasons not related to DOM element id. Fixed #6722.

• #6908 d77eaff Thanks @ematipico! - Fixed a bug where Biome didn't throw any error when vcs.useIgnoreFile is set to true, and there wasn't any ignore file read. Now Biome correctly throws an error if no ignore files are found.

• #6911 6d68074 Thanks @arendjr! - Fixed #6838: Reduce resource consumption in the Biome Language Server by using non-recursive filesystem watchers instead of recursive ones.

  Watchers are responsible for notifying Biome of changes to files in the filesystem. We used to set up a single recursive watcher, but that meant that Biome would receive filesystem notifications for all files in your project, even for ignored folders such as build/ or dist/ folders.

  With this patch, we set up non-recursive watchers only for the folders that are relevant to a project.

  Related to this, we also solved an issue where incoming notifications were incorrectly filtered, causing ignored files to be processed and stored in our module graph anyway.
