  Cristian Filipov

Enhancements

• None.

Bug Fixes

• Made Vertical Whitespace Rule added in 0.11.2 opt-in due to performance

0.11.1: Cuddles... Or Else!

Support for else on new line (uncuddled) and LegacyCGGeometryFunctionsRule fixes.

Breaking

• None.

Enhancements

• Added statement_mode configuration to the statement_position rule. The
  default mode keeps the current SwiftLint behavior of keeping else and
  catch statements on the same line as the closing brace before them. The
  uncuddled_elseconfiguration requires the else and catch to be on a new
  line with the same leading whitespace as the brace.
  Mike Skiba
  #651

Bug Fixes

• Remove extraneous argument label added in LegacyCGGeometryFunctionsRule
  autocorrect.

0.11.0: Laundromat Format

The big news in this release is that autocorrect will now optionally re-indent your Swift files like Xcode does.

Big thanks to Jorge Bernal, Norio Nomura, Brian Hardy, Reimar Twelker & Andrew Rahn for contributing to this release!

Breaking

• Now type_name allows lowercase enum values to match the Swift API Design
  Guidelines.
  Jorge Bernal
  #654
• Embedding frameworks needed by swiftlint was moved from
  SwiftLintFramework Xcode target to the swiftlint target.
  The SwiftLintFramework.framework product built by the
  SwiftLintFramework target no longer contains unnecessary frameworks or
  multiple copies of the Swift libraries.
  Norio Nomura

Enhancements

• Add --format option to autocorrect command which re-indents Swift files
  much like pasting into Xcode would. This option isn't currently configurable,
  but that can change if users request it.
  JP Simard
• Improve error messages for invalid configuration files.
  Brian Hardy
• Added the user-configurable option ignores_empty_lines to the
  trailing_whitespace rule. It can be used to control whether the
  TrailingWhitespaceRule should report and correct whitespace-indented empty
  lines. Defaults to false. Added unit tests.
  Reimar Twelker

Bug Fixes

• Fix false positive in conditional binding cascade violation.
  Norio Nomura
  #642
• Another conditional binding fix, this time for enum that has two parameters
  or an if statement with two case tests.
  Andrew Rahn
  #667
• Fix regression in CommaRule ignoring violations when the comma is followed
  by a comment.
  Norio Nomura
  #683

0.10.0: `laundry-select` edition

Here's the full list of changes:

Breaking

• None.

Enhancements

• Now libclang.dylib and sourcekitd.framework are dynamically loaded at
  runtime by SourceKittenFramework to use the versions included in the Xcode
  version specified by xcode-select -p or custom toolchains.
  Norio Nomura
  #167
• Add LegacyCGGeometryFunctionsRule rule.
  Sarr Blaise
  #625

  Josh Friend
  #592

  Norio Nomura
  #623

0.9.2: Multiple Exhaust Codes

Breaking

• None.

Enhancements

• Return different exit codes to distinguish between types of errors:
  • 0: No errors, maybe warnings in non-strict mode
  • 1: Usage or system error
  • 2: Style violations of severity "Error"
  • 3: No style violations of severity "Error", but violations of severity
    "warning" with --strict
    JP Simard
    #166

  letter to allow for names like XMLString or MIMEType.

0.9.0: Appliance Maintenance

This is a big release, with lots of breaking changes and deprecations for users of SwiftLintFramework. If we've removed functionality from the framework's public API that you were depending on, please let us know by filing an issue so we can consider adding it back in.

Breaking

• Linter.reporter has been removed and Configuration.reporterFromString(_:)
  has been renamed to a free function: reporterFromString(_:).
  JP Simard
• _ConfigProviderRule & ConfigurableRule have been removed and their
  requirements have been moved to Rule.
  JP Simard
• Configuration(path:optional:silent) has been changed to
  Configuration(path:rootPath:optional:quiet:).
  JP Simard
• The static function Configuration.rulesFromDict(_:ruleList:) has been moved
  to an instance method: RuleList.configuredRulesWithDictionary(_:).
  JP Simard
• The rules parameter in the Configuration initializer has been renamed to
  configuredRules.
  JP Simard
• Removed a large number of declarations from the public SwiftLintFramework API.
  This is being done to minimize the API surface area in preparation of a 1.0
  release. See #507 for a
  complete record of this change.
  JP Simard
  #479
• All instances of the abbreviation "config" in the API have been expanded to
  "configuration". The --config command line parameter and
  use_nested_configs configuration key are unaffected.
  JP Simard
• The use_nested_configs configuration key has been deprecated and its value
  is now ignored. Nested configuration files are now always considered.
  JP Simard

Enhancements

  overrides existing reporter values in the configuration file. Choose between
  xcode (default), json, csv or checkstyle.
  JP Simard
  #440
• swiftlint rules now shows a configuration description for all rules.
  JP Simard
• lint and autocorrect commands now accept a --quiet flag that prevents
  status messages like 'Linting ' & 'Done linting' from being logged.

• All top-level keys in a configuration file that accept an array now also
  accept a single value.
  e.g. included: Source is equivalent to included:\n - Source.
