Haste, short for Haskell Turbo-Edit was a Haskell IDE written in Haskell which used Wxhaskell as a GUI and a heavily modified version of haddock 1.x for Intellisense (tab-completion). It was announced Sun Apr 10 2005, by a group of students at Chalmers University. Its homepage was at http://haste.dyndns.org:8080 (the site has since gone down).
The development of Haste has been abandoned, and as of GHC 6.8.2, it is somewhat bitrotten. A snapshot of the last sources can be found at /~kolmodin/code/haste on haskell.org.
A successor to haste, haste2 (primarily developed by David Waern), has also been abandoned. Lennart Kolmodin describes haste2 thusly:
"It had some basics and could have become very exciting. It
had some integration with darcs, haddock2 (?) and a proper source code widget. It was based on using IO much, and we discussed it and were eager to try a more pure style, like xmonad to the X server. We would probably rewrite it pretty much from scratch if we'd continue. The current work is all done by Waern.pretty much dead too."
Waern also wrote pretty complete Scintilla bindings to the gtk2hs framework. Our previous bindings has been integrated into the wxHaskell project. Unfortunately the gkt2hs work got destroyed in a hard disk crash, and he was not able to recover it. That's the bindings haste2 relied on. As far as I know haste2 was also on that disk. It seems
