ktfmt is a program that pretty-prints (formats)
Kotlin code.
It always produces the same result, regardless of how the code looks initially, freeing developers to focus on essence.
It is by design non-customizable in order to promote consistency.
A ktfmt plugin that augments the Reformat Code action (⌥⌘L) is available from JetBrains Marketplace.
