Month in Haskell Mode November 2015

Welcome Haskell Mode users,

Haskell Mode progress report for November 2015.

For previous issue see October 2015.

Go to Reddit discussion.

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. For more information see https://github.com/haskell/haskell-mode.

Important developments

The bug that everybody was waiting for was fixed! No more 'Illegal token' in indentation. Rejoice!

Coming release

In the beginning of December we plan to tag new stable release of haskell-mode with current state of the repo (plus possible bugfixes).

Competitive projects

Haskell editor landscape is growing and there are compelling propositions all over the place:

• Atom IDE-Haskell
• Haskell Vim IDE
• Leksah - Haskell IDE in Haskell
• Haskell for Mac

There is an idea turning into reality that there should be a common infrastructure powering all of the above. It is brewing in Haskell IDE Engine repo.

Cruft removal, reminder

Last month we declared that we plan to remove some cruft. Note that SCC functions got salvaged and now they are fully functional part of haskell-mode! Killing list for December:

• Remove haskell-bot.el
• Remove horizontal whitespace based smart indentation mode haskell-simple-indent
• Remove Unicode input method
• Remove haskell-checkers.el

Current project focus

Current project focus is to lower entry barrier for newcomers by defining bite-sized tasks.

Get 50 'well-defined-tasks' done as by the metric:

https://github.com/haskell/haskell-mode/issues?q=is%3Aissue+label%3Awell-defined-task+is%3Aclosed

A 'well-defined-task' is a category of tasks that have the field cleared for them, questions already sorted out and detailed information how to get them done. So you can just sit, search for 'well-defined-task' label and enjoy the coding! The point is to lower the entry barrier for new users, new issue reporters and advanced programmers but Emacs lisp beginners to contribute to the project.

Current status: 14 well-defined-tasks closed plus 13 more open.

If only you can help with reaching our targets please do so!
