Yi 0.5.0 Release Notes


Yi is a text editor written and extensible in Haskell. The long-term goal of the Yi project is to provide the editor of choice for Haskell programmers.

Yi is not a finished product. This is a beta-quality release. However, Yi has become a lot more usable than previously, so if you feel like testing it, now might be a good time to take a look.


Using cabal install:

cabal install yi–

If you want unix console support, pass the -fvty option to cabal install.


  • A purely functional editor core
  • Key-bindings written as parsers of the input
  • Emacs, Vim and partial Cua emulations provided by default
  • Unix Console front-end (Gtk2Hs frontend is not supported in this release)
  • Static configuration (XMonad style) for fast load
  • Haskell support:
    • Lexical highlighting
    • Layout-aware parenthesis-matching
    • Auto-indentation
    • Call cabal build within the editor


This release is brought to you by:

  • Allan Clark
  • Corey O’Connor
  • Gustav Munkby
  • Gwern Branwen
  • Jean-Philippe Bernardy
  • Jeff Wheeler
  • Nicolas Pouillard
  • Thomas Schilling
  • Tristan Allwood

and all the contributors to the previous versions.
