CLI

Bug fixes

• Fix #3201 by correctly injecting the source code of the file when printing the diagnostics. Contributed by @ematipico
• Fix #3179 where comma separators are not correctly removed after running biome migrate and thus choke the parser. Contributed by @Sec-ant
• Fix #3232 by correctly using the colors set by the user. Contributed by @ematipico

Enhancement

• Reword the reporter message No fixes needed to No fixes applied.

  The former message is misleading when there're still errors or warnings in the files that should be taken care of manually. For example:

  Checked 2 files in <TIME>. No fixes needed.
  Found 2 errors.
  

  The new message suits better in these cases.

Configuration

Bug fixes

• Don't conceal previous overrides (#3176).

  Previously, each override inherited the unset configuration of the base configuration. This means that setting a configuration in an override can be concealed by a subsequent override that inherits of the value from the base configuration.

  For example, in the next example, noDebugger was disabled for the index.js file.

  {
    "linter": {
      "rules": {
        "suspicious": { "noDebugger": "off" }
      }
    },
    "overrides": [
      {
        "include": ["index.js"],
        "linter": {
          "rules": {
            "suspicious": { "noDebugger": "warn" }
          }
        }
      }, {
        "include": ["index.js"],
        "linter": {
          "rules": {
            "suspicious": { "noDoubleEquals": "off" }
          }
        }
      }
    ]
  }
  

  The rule is now correctly enabled for the index.js file.

• Add nursery/useValidAutocomplete. Contributed by @unvalley

Bug fixes

• Add nursery/noShorthandPropertyOverrides. #2958 Contributed by @neokidev

• Fix [#3084] false positive by correctly recognize parenthesized return statement. Contributed by @unvalley

• The useHookAtTopLevel rule now recognizes properties named as hooks like foo.useFoo(). Contributed by @ksnyder9801

• Fix #3092, prevent warning for Custom properties (--*). Contributed by @chansuke

• Fix a false positive in the useLiteralKeys rule. (#3160)

  This rule now ignores the following kind of computed member name:

  const a = {
    [`line1
    line2`]: true,
  };
  

  Contributed by @Sec-ant

• The noUnknownProperty rule now ignores the composes property often used in css modules. #3000 Contributed by @chansuke

• Fix false positives of the useExhaustiveDependencies rule.

  The component itself is considered stable when it is used recursively inside a hook closure defined inside of it:

  import { useMemo } from "react";
  
  function MyRecursiveComponent() {
    // MyRecursiveComponent is stable, we don't need to add it to the dependencies list.
    const children = useMemo(() => <MyRecursiveComponent />, []);
    return <div>{children}</div>;
  }
  

  Also, export default function and export default class are considered stable now because they can only appear at the top level of a module.
