Change max-width parameter to tests to a nicer API Summary: This lets us write a line of ---------- in the beginning of a test to set the max width, which makes it easier to reason about what is going to happen. Updated all simple tests to use this. Reviewed By: cgrushko Differential Revision: D19898883 fbshipit-source-id: 6277982952397077b334b6447ad3bc06071728cc
ktfmt
is a program that pretty-prints (formats) Kotlin code, based on google-java-format.
Note that ktfmt
still has some rough edges which we're constantly working on fixing.

For comparison, the same code formatted by ktlint
and IntelliJ:

ktfmt
vs ktlint
vs IntelliJktfmt
uses google-java-format's underlying engine, and as such, many items on google-java-format's FAQ apply to ktfmt
as well.
In particular,
ktfmt
ignores most existing formatting. It respects existing newlines in some places, but in general, its output is determinstic and is independent of the input code.ktfmt
exposes no configuration options that govern formatting behavior. See https://github.com/google/google-java-format/wiki/FAQ#i-just-need-to-configure-it-a-bit-differently-how for the rationale.These two properties make ktfmt
a good fit in large Kotlin code bases, where consistency is very important.
We created ktfmt
because ktlint
and IntelliJ sometime fail to produce nice-looking code that fits in 100 columns, as can be seen in the Demo section.
ktfmt
uses a 2-space indent; why not 4?Two reasons -
