0.31.0

Added

• dot-spacing rule (#293).
• experimental/indent rule (#338).
  Use ktlint --experimental to enable.

Fixed

• Spacing check around < & > operators.

Changed

• no-multi-spaces rule (horizontal alignment of comments is no longer allowed) (#269).
• colon-spacing rule (: must not appear at the beginning of the line).
• package-name rule (disabled until #208 is resolved).
• --print-ast to output com.github.shyiko.ktlint.core.ast.ElementType.* as node.elementType, e.g.

$ echo 'fun f() {}' | ./ktlint/target/ktlint --print-ast --color --stdin
