Intellij Plugin v0.0.4

Analyzer

Enhancements

• Import sorting is safe to apply now, and it will be applied when running check --apply instead of check --apply-unsafe.

• Import sorting now handles Bun imports bun:<name>, absolute path imports /<path>, and Node's subpath imports #<name>. See our documentation for more details. Contributed by @Conaclos

CLI

Bug fixes

• Fix #319. The command biome lint now shows the correct options. Contributed by @ematipico
• Fix #312. Running biome --version now exits with status code 0 instead of 1. Contributed by @nhedger
• Fix a bug where the extends functionality doesn't carry over organizeImports.ignore. Contributed by @ematipico
• The CLI now returns the original content when using stdin and the original content doesn't change. Contributed by @ematipico

New features

• Add support for BIOME_BINARY environment variable to override the location of the binary. Contributed by @ematipico

• Add option --indent-width, and deprecated the option --indent-size. Contributed by @ematipico

• Add option --json-formatter-indent-width, and deprecated the option --json-formatter-indent-size. Contributed by @ematipico

• Add option --daemon-logs to biome rage. The option is required to view Biome daemon server logs. Contributed by @unvalley

• Add support for logging. By default, Biome doesn't log anything other than diagnostics. Logging can be enabled with the new option --log-level:

  biome format --log-level=info ./src

  There are four different levels of logging, from the most verbose to the least verbose: debug, info, warn and error. Here's how an INFO log will look like:

  2023-10-05T08:27:01.954727Z  INFO  Analyze file ./website/src/playground/components/Resizable.tsx
    at crates/biome_service/src/file_handlers/javascript.rs:298 on biome::worker_5
    in Pulling diagnostics with categories: RuleCategories(SYNTAX)
    in Processes formatting with path: "./website/src/playground/components/Resizable.tsx"
    in Process check with path: "./website/src/playground/components/Resizable.tsx"
  

  You can customize how the log will look like with a new option --log-kind. The supported kinds are: pretty, compact and json.

  pretty is the default logging. Here's how a compact log will look like:

Enhancements

• Deprecated the environment variable ROME_BINARY. Use BIOME_BINARY instead. Contributed by @ematipico
• Biome doesn't check anymore the presence of the .git folder when VCS support is enabled. Contributed by @ematipico
• biome rage doesn't print the logs of the daemon, use biome rage --daemon-logs to print them. Contributed by @unvalley

Configuration

New features

• Add option formatter.indentWidth, and deprecated the option formatter.indentSize. Contributed by @ematipico

• Add option javascript.formatter.indentWidth, and deprecated the option javascript.formatter.indentSize. Contributed by @ematipico

• Add option json.formatter.indentWidth, and deprecated the option json.formatter.indentSize. Contributed by @ematipico

• Add option include to multiple sections of the configuration

  • files.include;
  • formatter.include;
  • linter.include;
  • organizeImports.include;
    When include and ignore are both specified, ignore takes precedence over include

• Add option overrides, where users can modify the behaviour of the tools for certain files or paths.

  For example, it's possible to modify the formatter lineWidth, and even quoteStyle for certain files that are included in glob path generated/**:

  {
    "formatter": {
      "lineWidth": 100
    },
    "overrides": [
      {
        "include": ["generated/**"],
        "formatter": {
          "lineWidth": 160
        },
        "javascript": {
          "formatter": {
            "quoteStyle": "single"
          }
        }
      }
    ]
  }

  Or, you can disable certain rules for certain path, and disable the linter for other paths:

  {
    "linter": {
      "enabled": true,
      "rules": {
        "recommended": true
      }
    },
    "overrides": [
      {
        "include": ["lib/**"],
        "linter": {
          "rules": {
            "suspicious": {
              "noDebugger": "off"
            }
          }
        }
      },
      {
        "include": ["shims/**"],
        "linter": {
          "enabled": false
        }
      }
    ]

Bug fixes

• Fix #243 a false positive case where the incorrect scope was defined for the infer type. in rule noUndeclaredVariables. Contributed by @denbezrukov
• Fix #322, now noSelfAssign correctly handles literals inside call expressions.
• Changed how noSelfAssign behaves. The rule is not triggered anymore on function calls. Contributed by @ematipico

New features

• Add noEmptyCharacterClassInRegex rule. The rule reports empty character classes and empty negated character classes in regular expression literals. Contributed by @Conaclos

• Add noMisleadingInstantiator rule. The rule reports the misleading use of the new and constructor methods. Contributed by @unvalley

• Add noUselessElse rule.
  The rule reports else clauses that can be omitted because their if branches break.
  Contributed by @Conaclos

• Add noUnusedImports rule.
  The rule reports unused imports and suggests to remove them.
  Contributed by @Conaclos

  noUnusedVariables reports also unused imports, but don't suggest their removal.
  Once noUnusedImports stabilized,
  noUnusedVariables will not report unused imports.

• Add useShorthandAssign rule.
  The rule enforce use of shorthand operators that combine variable assignment and some simple mathematical operations. For example, x = x + 4 can be shortened to x += 4.
  Contributed by @victor-teles

• Add useAsConstAssertion rule.
  The rule enforce use of as const assertion to infer literal types.
  Contributed by @unvalley

Enhancements

• The following rules have now safe code fixes:

  • noNegationElse
  • noUselessLabel
  • noUselessTypeConstraint
  • noUnusedLabels
  • useConst
  • useEnumInitializers
  • useWhile

• noUnusedLabels no longer reports unbreakable labeled statements. Contributed by @Conaclos

• noUnusedVariables now reports unused TypeScript's type parameters. Contributed by @Conaclos

Bug fixes

• Fix #294. noConfusingVoidType no longer reports false positives for return types. Contributed by @b4s36t4

• Fix #313. noRedundantUseStrict now keeps leading comments.

• Fix #383. noMultipleSpacesInRegularExpressionLiterals now provides correct code fixes when consecutive spaces are followed by a quantifier. Contributed by @Conaclos

• Fix #397. useNumericLiterals now provides correct code fixes for signed numbers. Contributed by @Conaclos

• Fix 452. The linter panicked when it met a malformed regex (a regex not ending with a slash).

Parser

• Enhance diagnostic for infer type handling in the parser. The 'infer' keyword can only be utilized within the 'extends' clause of a conditional type. Using it outside of this context will result in an error. Ensure that any type declarations using 'infer' are correctly placed within the conditional type structure to avoid parsing issues. Contributed by @denbezrukov

• Add support for parsing trailing commas inside JSON files:

  {
    "json": {
      "parser": {
        "allowTrailingCommas": true
      }
    }
  }

Promoted rules

New rules are incubated in the nursery group.
Once stable, we promote them to a stable group.
The following rules are promoted:

• a11y/noAriaUnsupportedElements
• a11y/noNoninteractiveTabindex
• a11y/noRedundantRoles
• a11y/useValidAriaValues
• complexity/noBannedTypes
• complexity/noStaticOnlyClass
• complexity/noUselessEmptyExport
• complexity/noUselessThisAlias
• correctness/noConstantCondition
• correctness/noNonoctalDecimalEscape
• correctness/noSelfAssign
• style/useLiteralEnumMembers
• style/useNamingConvention
• suspicious/noControlCharactersInRegex
• suspicious/noUnsafeDeclarationMerging
• suspicious/useGetterReturn

New rules

• Add noConfusingVoidType rule. The rule reports the unusual use of the void type. Contributed by @shulandmimi

Removed rules

• Remove noConfusingArrow.

  Code formatters, such as prettier and Biome, always adds parentheses around the parameter or the body of an arrow function.
  This makes the rule useless.

  Contributed by @Conaclos

Enhancements

• noFallthroughSwitchClause now relies on control flow analysis to report most of switch clause fallthrough. Contributed by @Conaclos

• noAssignInExpressions no longer suggests code fixes. Most of the time the suggestion didn't match users' expectations. Contributed by @Conaclos

• noUselessConstructor no longer emits safe code fixes. Contributed by @Conaclos

  All code fixes are now emitted as unsafe code fixes.
  Removing a constructor can change the behavior of a program.

• useCollapsedElseIf now only provides safe code fixes. Contributed by @Conaclos

• noUnusedVariables now reports more cases.

  The rule is now able to ignore self-writes.
  For example, the rule reports the following unused variable:

  let a = 0;
  a++;
  a += 1;

  The rule is also capable of detecting an unused declaration that uses itself.
  For example, the rule reports the following unused interface:

  interface I {
    instance(): I
  }

  Finally, the rule now ignores all TypeScript declaration files,
  including global declaration files.

Bug fixes

• Fix #182, making useLiteralKeys retains optional chaining. Contributed by @denbezrukov

• Fix #168, fix useExhaustiveDependencies false positive case when stable hook is on a new line. Contributed by @denbezrukov

• Fix #137, fix noRedeclare false positive case with TypeScript module declaration:

  declare module '*.gif' {
      const src: string;
  }
  
  declare module '*.bmp' {
      const src: string;
  }

• Fix #266, where complexity/useLiteralKeys emitted a code action with an invalid AST. Contributed by @ematipico

• Fix #105, removing false positives reported by noUnusedVariables.

  The rule no longer reports the following used variable:

  const a = f(() => a);

  Contributed by @Conaclos

VSCode

Enhancements

• Improve server binary resolution when using certain package managers, notably pnpm.

  The new strategy is to point to node_modules/.bin/biome path,
  which is consistent for all package managers.
