Added

• --android (-a) CLI option (turns on Android Kotlin Style Guide compatibility)

Fixed

0.10.2

This release contains changes that were meant for 0.11.0 and so it was retagged as such.

0.10.1

Fixed

• Redundant space inserted between } and [key]/(...) (curly-spacing) (#91).

0.10.0

Added

• Git hook to automatically check files for style violations on commit
  (execute ktlint --install-git-pre-commit-hook to install).
• Ability to specify multiple reporters
  (output can be controlled with --reporter=<name>,output=<path/to/file>) (#71).
• Support for indent_size=unset (.editorconfig) (#70).

Fixed

• ( { formatting
  (previously both ( { and ({ were accepted as correct, while only ({ should be) (curly-spacing rule) (#80).
• if\nfn {}\nelse formatting (curly-spacing rule).
• max_line_length=off & max_line_length=unset handling (.editorconfig).

Changed

• kotlin-compiler version to 1.1.51 (from 1.1.3-2).
• ktlint --apply-to-idea to include OPTIMIZE_IMPORTS_ON_THE_FLY=true.

0.9.2

Fixed

• : Unit = formatting (: Unit is no longer dropped when = is used) (#77).

0.9.1

Fixed

• ${super.toString()} linting (string-template rule) (#69).

0.9.0

Added

• Reporter API.
  ktlint comes with 3 built-in reporters: plain (default; ?group_by_file can be appended to enable grouping by file (shown below)), json and checkstyle.

$ ktlint --reporter=plain?group_by_file
path/to/file.kt
  1:10 Unused import.
  2:10 Unnecessary "Unit" return type.
path/to/another-file.kt
  1:10 Unnecessary semicolon.

• string-template,
  no-empty-class-body,
  max-line-length (#47),
  final-newline (activated only if insert_final_newline is set in .editorconfig (under [*.{kt,kts}])) rules.
• --limit CLI option (e.g. use --limit=10 to limit the number of errors to display).
• --relative CLI flag which makes ktlint output file paths relative to working directory (e.g. dir/file.kt instead of
  /home/269/project/dir/file.kt).

Changed

• BREAKING: JDK version to 1.8 (as a result of upgrading kotlin-compiler to 1.1.3-2 (from 1.1.0)).
• file matching (offloaded to klob).

Deprecated

• --ruleset-repository and --ruleset-update CLI arguments in favour of --repository and --repository-update
  respectively (--ruleset-* will be removed in 1.0.0).
• ktlint-intellij-idea-integration binary
  (Intellij IDEA integration task is now included in ktlint (as ktlint --apply-to-idea)).
