New EXPERIMENTAL search command. The search command allows you to search a Biome project using GritQL syntax.

GritQL is a powerful language that lets you do structural searches on your codebase. This means that trivia such as whitespace or even the type of strings quotes used will be ignored in your search query. It also has many features for querying the structure of your code, making it much more elegant for searching code than regular expressions.

While we believe this command may already be useful to users in some situations (especially when integrated in the IDE extensions!), we also had an ulterior motive for adding this command: We intend to utilize GritQL for our plugin efforts, and by allowing our users to try it out in a first iteration, we hope to gain insight in the type of queries you want to do, as well as the bugs we need to focus on.

For now, the search command is explicitly marked as EXPERIMENTAL, since many bugs remain. Keep this in mind when you try it out, and please let us know your issues!

Note: GritQL escapes code snippets using backticks, but most shells interpret backticks as command invocations. To avoid this, it's best to put single quotes around your Grit queries.
```
biome search '`console.log($message)`' # find all `console.log` invocations
```

The --verbose flag now reports the list of files that were evaluated, and the list of files that were fixed. The evaluated files are the those files that can be handled by Biome, files that are ignored, don't have an extension or have an extension that Biome can't evaluate are excluded by this list. The fixed files are those files that were handled by Biome and changed. Files that stays the same after the process are excluded from this list.

Allow passing nursery to the --only and --skip filters.

The --only option allows you to run a given rule or rule group. The --skip option allows you to skip the execution of a given group or a given rule.

Previously, it was not possible to pass nursery. This restriction is now removed, as it may make sense to skip the nursery rules that a project has enabled.

The CLI now returns an error code when calling a command in stdin mode, and the contents of the files aren't fixed. For example, the following example will result in an error code of 1 because the lint command triggers some lint rules:

Configuration

Add support for loading configuration from .editorconfig files (#1724).

Configuration supplied in .editorconfig will be overridden by the configuration in biome.json. Support is disabled by default and can be enabled by adding the following to your formatter configuration in biome.json:
```
{
  "formatter": {
    "useEditorconfig": true
  }
}
```
Contributed by @dyc3

overrides from an extended configuration is now merged with the overrides of the extension.

Given the following shared configuration biome.shared.json:

{
  "overrides": [
    {
      "include": ["**/*.json"],
      // ...
    }
  ]
}

and the following configuration:

  "extends": ["./biome.shared.json"],
  "overrides": [
    {
      "include": ["**/*.ts"],
      // ...

useFilenamingConvention now supports unicase letters.

unicase letters have a single case: they are neither uppercase nor lowercase. Biome now accepts filenames in unicase. For example, the filename 안녕하세요 is now accepted.

We still reject a name that mixes unicase characters with lowercase or uppercase characters. For example, the filename A안녕하세요 is rejected.

This change also fixes #3353. Filenames consisting only of numbers are now accepted.

Contributed by @Conaclos
useFilenamingConvention now supports Next.js/Nuxt/Astro dynamic routes (#3465).

Next.js, SolidStart, Nuxt, and Astro support dynamic routes such as [...slug].js and [[...slug]].js.

Biome now recognizes this syntax. slug must contain only alphanumeric characters.

Contributed by @Conaclos
useExportType no longer reports empty export (#3535).

An empty export {} allows you to force TypeScript to consider a file with no imports and exports as an EcmaScript module. While export type {} is valid, it is more common to use export {}. Users may find it confusing that the linter asks them to convert it to export type {}. Also, a bundler should be able to remove export {} as well as export type {}. So it is not so useful to report export {}.

noRedeclare no longer report redeclartions for lexically scoped function declarations #3664.

In JavaScript strict mode, function declarations are lexically scoped: they cannot be accessed outside the block where they are declared.

In non-strict mode, function declarations are hoisted to the top of the enclosing function or global scope.

Previously Biome always hoisted function declarations. It now takes into account whether the code is in strict or non strict mode.

The JSON parser now allows comments in files with the .json extension under the .vscode and .zed directories.

Biome recognizes are well known JSON files that allows comments and/or trailing commas. Previously, Biome did not recognize JSON files under the .vscode and the .zed directories as JSON files that allow comments. You had to configure Biome to recognize them:
```
{
  "overrides": [

      "include": ["**/.vscode/*.json", "**/.zed/*.json"],
      "json": { "parser": { "allowComments": true } }

Enhancements

Enhance tailwind sorting lint rule #1274 with variant support.

Every preconfigured variant is assigned a weight that concurs on establishing the output sorting order. Since nesting variants on the same utility class is possible, the resulting weight is the Bitwise XOR of all the variants weight for that class. Dynamic variants (e.g. has-[.custom-class], group-[:checked]) are also supported and they take the weight of their base variant name the custom value attached (e.g. has-[.custom-class] takes has weight). Arbitrary variants (e.g. [&nth-child(2)]) don't have a weight assigned and they are placed after every known variant. Classes with the same amount of arbitrary variants follow lexicographical order. The class that has the highest number of nested arbitrary variants is placed last. Screen variants (e.g. sm:, max-md:, min-lg:) are not supported yet.

CLI

New features

New clean command. Use this new command to clean after the biome-logs directory, and remove all the log files.
```
biome clean
```
Add two new options --only and --skip to the command biome lint (#58).

The --only option allows you to run a given rule or rule group, For example, the following command runs only the style/useNamingConvention and style/noInferrableTypes rules. If the rule is disabled in the configuration, then its severity level is set to error for a recommended rule or warn otherwise.
```
biome lint --only=style/useNamingConvention --only=style/noInferrableTypes
```
Passing a group does not change the severity level of the rules in the group. All the disabled rules in the group will remain disabled. To ensure that the group is run, the recommended field of the group is enabled. The nursery group cannot be passed, as no rules are enabled by default in the nursery group.

The --skip option allows you to skip the execution of a given group or a given rule. For example, the following command skips the style group and the suspicious/noExplicitAny rule.
```
biome lint --skip=style --skip=suspicious/noExplicitAny
```
You can also use --only and --skip together. --skip overrides --only. The following command executes only the rules from the style group, but the style/useNamingConvention rule.
```
biome lint --only=style --skip=style/useNamingConvention
```
These options are compatible with other options such as --write (previously --apply), and --reporter.

Add new command biome clean. Use this command to purge all the logs emitted by the Biome daemon. This command is really useful, because the Biome daemon tends log many files and contents during its lifecycle. This means that if your editor is open for hours (or even days), the biome-logs folder could become quite heavy. Contributed by @ematipico
Add support for formatting and linting CSS files from the CLI. These operations are opt-in for the time being.

If you don't have a configuration file, you can enable these features with --css-formatter-enabled and --css-linter-enabled:
```
biome check --css-formatter-enabled=true --css-linter-enabled=true ./
```
Contributed by @ematipico
Add new CLI options to control the CSS formatting. Check the CLI reference page for more details. Contributed by @ematipico
Add new options --write, --fix (alias of --write) and --unsafe to the command biome lint and biome check. Add a new option --fix (alias of --write) to the command biome format and biome migrate.
```
biome <lint|check> --<write|fix> [--unsafe]
biome format --<write|fix>
biome migrate --<write|fix>
```
The biome <lint|check> --<write|fix> has the same behavior as biome <lint|check> --apply. The biome <lint|check> --<write|fix> --unsafe has the same behavior as biome <lint|check> --apply-unsafe. The biome format --fix has the same behavior as biome format --write. The biome migrate --fix has the same behavior as biome migrate --write.

This change allows these commands to write modifications in the same options. With this change, the --apply and --apply-unsafe options are deprecated.

Biome now executes commands (lint, format, check and ci) on the working directory by default. #2266 Contributed by @unvalley
```
- biome check .
+ biome check    # You can run the command without the path
```
biome migrate eslint now tries to convert ESLint ignore patterns into Biome ignore patterns.

ESLint uses gitignore patterns. Biome now tries to convert these patterns into Biome ignore patterns.

For example, the gitignore pattern /src is a relative path to the file in which it appears. Biome now recognizes this and translates this pattern to ./src.

Contributed by @Conaclos
biome migrate eslint now supports the eslintIgnore field in package.json.

ESLint allows the use of package.json as an ESLint configuration file. ESLint supports two fields: eslintConfig and eslintIgnore. Biome only supported the former. It now supports both.

Contributed by @Conaclos
biome migrate eslint now propagates NodeJS errors to the user.

This will help users to identify why Biome is unable to load some ESLint configurations.

Add a new --reporter called summary. This reporter will print diagnostics in a different way, based on the tools (formatter, linter, etc.) that are executed. Import sorting and formatter shows the name of the files that require formatting. Instead, the linter will group the number of rules triggered and the number of errors/warnings:

Formatter ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
The following files needs to be formatted:
main.ts
index.ts

Organize Imports ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
The following files needs to have their imports sorted:

Configuration

New features

Add an rule option fix to override the code fix kind of a rule (#2882).

A rule can provide a safe or an unsafe code action. You can now tune the kind of code actions thanks to the fix option. This rule option takes a value among:
- none: the rule no longer emits code actions.
- safe: the rule emits safe code action.
- unsafe: the rule emits unsafe code action.
The following configuration disables the code actions of noUnusedVariables, makes the emitted code actions of style/useConst and style/useTemplate unsafe and safe respectively.
```
{
  "linter": {
    "rules": {
      "correctness": {
        "noUnusedVariables": {
          "level": "error",
          "fix": "none"
        },
        "style": {
          "useConst": {
            "level": "warn",

Bug fixes

noUndeclaredVariables and noUnusedImports now correctly handle import namespaces (#2796).

Previously, Biome bound unqualified type to import namespaces. Import namespaces can only be used as qualified names in a type (ambient) context.

// Unused import
import * as Ns1 from "";
// This doesn't reference the import namespace `Ns1`
type T1 = Ns1; // Undeclared variable `Ns1`

// Unused import
import type * as Ns2 from "";
// This doesn't reference the import namespace `Ns2`
type T2 = Ns2; // Undeclared variable `Ns2`

import type * as Ns3 from "";
// This references the import namespace because it is a qualified name.
type T3 = Ns3.Inner;
// This also references the import namespace.
export type { Ns3 }

Contributed by @Conaclos

noUndeclaredVariables now correctly handle ambient computed member names (#2975).

A constant can be imported as a type and used in a computed member name of a member signature. Previously, Biome was unable to bind the value imported as a type to the computed member name.
```
import type { NAME } from "./constants.js";
type X = { [NAME]: number };
```
Contributed by @Conaclos
noUndeclaredVariables now ignores this in JSX components (#2636).
