Welcome Haskell Mode users,

Haskell Mode progress report for April 2016 (online).

For previous issue see March 2016. Discussion on reddit.

What is Haskell Mode?

Haskell Mode is an umbrella project for multiple Emacs tools for efficient Haskell development. Haskell Mode is an open source project developed by a group of volunteers constantly looking for contributions. For more information how to help see https://github.com/haskell/haskell-mode.

Important developments

April was a very active month.

We managed to move most of the wiki content to manual proper, ensuring some cleanup along the way removing redundant, outdated or just plainly confusing documentation. Some sections of the manual were significantly expanded.

Indentation saw three significant changes:

  • haskell-indentation-indent-leftmost customization variable was removed
  • in many cases indentation now offers more sutable indentation points than it used to
  • the deriving keyword got special tratment both in standalone deriving and as part of standard and GADT data syntax.

Types are now colorized differently provided that you set haskell-type-face to something different than haskell-constructor-face. We are looking for a suitable color theme.

Haskell Mode now requires Emacs 24.3 minimum.
