Package ormolu

https://hackage.haskell.org/package/ormolu

Ormolu is a formatter for Haskell source code.
The project was created with the following goals in mind:

- Using GHC's own parser to avoid parsing problems caused by haskell-src-exts.

- Let some whitespace be programmable. The layout of the input
  influences the layout choices in the output. This means that the
  choices between single-line/multi-line layouts in each particular
  situation are made by the user, not by an algorithm. This makes the
  implementation simpler and leaves some control to the user while
  still guaranteeing that the formatted code is stylistically
  consistent.

- Writing code in such a way so it's easy to modify and maintain.

- Implementing one “true” formatting style which admits no configuration.

- That formatting style aims to result in minimal diffs while still
  remaining very close to “conventional” Haskell formatting people
  use.

- Choose a style compatible with modern dialects of Haskell. As new
  Haskell extensions enter broad use, we may change the style to
  accommodate them.

- Idempotence: formatting already formatted code doesn't change it.

- Be well-tested and robust to the point that it can be used in large
  projects without exposing unfortunate, disappointing bugs here and
  there.
