js-api/v0.7.1

2670095

JavaScript APIs v0.7.1

CLI

New features

GritQL queries that match functions or methods will now match async functions or methods as well.

If this is not what you want, you can capture the async keyword (or its absence) in a metavariable and assert its emptiness:
```
$async function foo() {} where $async <: .
```

CLI v1.9.2

CLI

New features

Added support for custom GritQL definitions, including:
- Pattern and predicate definitions: https://docs.grit.io/guides/patterns
- Function definitions: https://docs.grit.io/language/functions#function-definitions
Contributed by @arendjr

Bug fixes

Fix #3917, where the fixed files were incorrectly computed. Contributed by @ematipico
Fixed an issue that caused GritQL contains queries to report false positives when the matched
node appeared inside a sibling node. Contributed by @arendjr

Editors

Bug fixes

Fix #3923. Now the .editorconfig is correctly parsed by the LSP, and the options are correctly applied to files when formatting is triggered.
Plus, the Biome LSP now watches for any change to the .editorconfig, and updates the formatting settings.
Reduced the number of log files generated by the LSP server. Now the maximum number of logs saved on disk is seven. Contributed by @ematipico
Fix the code actions capabilities available in the LSP Biome server. Before, the LSP was using the default capabilities, which resulted in pulling code actions even when they were disabled by the editor.

This means that the code actions are pulled by the client only when the editor enables quickfix.biome, source.organizeImports.biome and source.fixAll.biome.

Now, if you enable organizeImports.enabled: true in the biome.json, and then you configure your editor with the following code action source.organizeImports.biome: false, the editor won't sort the imports.

New features

Add --graphql-linter-enabled option, to control whether the linter should be enabled or not for GraphQL files. Contributed by @ematipico
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
```

Add new options to the lsp-proxy and start commands:
- --log-path: a directory where to store the daemon logs. The commands also accepts the environment variable BIOME_LOG_PATH.
- --log-prefix-name: a prefix that's added to the file name of the logs. It defaults to server.log. The commands also accepts the environment variable BIOME_LOG_PREFIX_NAME.
@contributed by @ematipico

Enhancements

When a --reporter is provided, and it's different from the default one, the value provided by via --max-diagnostics is ignored and the limit is lifted. Contributed by @ematipico
biome init now generates a new config file with more options set.
This change intends to improve discoverability of the options and to set the more commonly used options to their default values.
Contributed by @Conaclos

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.

Contributed by @Conaclos
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:
```
echo "let x = 1" | biome lint --stdin-file-path=stdin.js

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
  }
}
```

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"],
      // ...
    }
  ]
}

Previously, the overrides from biome.shared.json was overwritten.
It is now merged and results in the following configuration:

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

New features

Add --graphql-linter-enabled option, to control whether the linter should be enabled or not for GraphQL files. Contributed by @ematipico
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
```

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.

Contributed by @Conaclos
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:

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 report 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 {}.

Contributed by @Conaclos
noUnusedVariables now checks TypeScript declaration files.

This allows to report a type that is unused because it isn't exported.
Global declarations files (declarations files without exports and imports) are still ignored.

useNamingConvention now accepts applying custom convention on abstract classes. Contributed by @Conaclos
useNamingConvention no longer suggests an empty fix when a name doesn't match strict Pascal case (#3561).

Previously the following code led useNamingConvention to suggest an empty fix.
The rule no longer provides a fix for this case.
```
type AAb = any
```
Contributed by @Conaclos
useNamingConvention no longer provides fixes for global TypeScript declaration files.

Global TypeScript declaration files have no epxorts and no imports.
All the declared types are available in all files of the project.
Thus, it is not safe to propose renaming only in the declaration file.

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.
