Generic Information
You can apply for an account and a project using the community server. Ping Igloo on #haskell-hac07 and he'll create the account. You can also apply for a project.
Once you have an account and a project, you upload a Darcs repository as follows. First, initialize your repository on the server:
$ ssh community.haskell.org you@haskell:~$ cd /srv/code/yourproject you@haskell:/srv/code/yourproject$ darcs init
Then, log out and push your repository:
$ darcs push community.haskell.org:/srv/code/yourproject
Who knows about what
A list of projects you've worked on or know fairly well:

| skogsbaer (Stefan Wehr) | hscurses, rhaskell |
| Pepe | ghc (front end mostly), ghci debugger, cabal-install (very little) |

| kolmodin (Lennart Kolmodin) | Data.Binary, Gentoo Linux, Haste (Haskell Turbo-Edit,a Haskell IDE in Haskell), hackport (hackage for Gentoo), hinotify, dbus-haskell |
| Heffalump (Ganesh Sittampalam) | darcs patch theory |
| conal (Conal Elliott) | functional reactive programming, DataDriven evaluation, tangible functional programming, graphics, embedded compilers, applicative functors, wxHaskell |
Active Projects
Please feel free to describe your current project here!
Cabal
ByteString network
Change Network.* to use strict ByteStrings instead of Strings. It would also be nice to tidy up the #ifdef mess.
Current hacker(s): tibbe (Johan Tibell)
Data.Binary
updating to 6.8
Current hackers: dons
Probability monads
A really cool existing implementation: Probabilistic functional programming
Darcs repository and draft paper.
Things to work on:
- Get MaybeT into Hackage.
- Is WriterT really the right monad transformer? We want the join and bind operations, but not the rest of the MonadWriter type class.
- Should probabilities be represented as floats, fractions or a type class?
- Can this run fast enough to be useful?
Done:
- MaybeT docs and Darcs repository. This should have all the features of New_monads/MaybeT, except for the potentially ambiguous MonadPlus instance.
- MonadRandom is now documented and packaged.
Current hacker(s): ekidd (Eric Kidd)
Yi hacking
Yi needs a lot of love and doesn't work out of the box for me. One of the nice thing to try to do is to add the collaborative editing plugin to yi (in the spirit of the Gobby editor).
- vincenz: Definitely would like to add some usability input here regarding Gobby functionality (having used it and having found it lacking in several areas, areas that could be improved through reusing some darcs theory).
- ivant: also need to add unicode support to yi
- vincenz: Move away from System.Filepath to something std supported
- Cabalize the current 'Setup.hs' *Cabal hackers welcome for help*
- Update the regex dependencies to work with the newest one.
- Work splatch into Yi
Current hacker(s): ivant (Ivan Tarasov), vincenz (Christophe Poucet)
Splatch
Patching of splices, or otherwise said, a patch-model for working concurrently on one piece of text.
Current hacker(s): ivant (Ivan Tarasov), vincenz (Christophe Poucet)
Tangible functional programming
Some to-do items:
- More built-ins
- Save
- Improved user experience for gestural composition, e.g., drag & drop
- Does it work on MacOS? Linux?
- Sum types
- Code generation via hs-plugins or ghc-api or Harpy.
Current hacker(s): conal
General composition tools
TypeCompose: some classes & instances for forms of type composition (including contravariant functors and applicative functors)
Current hacker(s): conal
Deep arrows
DeepArrow: a framework for composable "editors" of pure values
Current hacker(s): conal
Source browsing
TiddlyWiki-based code & documentation browser. Syntax-colored and all identifiers fully hyperlinked to sources. Thanks to TiddlyWiki, the browsing experience is fluid & self-organizing.
Bring together disparate functionality from HsColour & Haddock, and add auto-generated hyperlinking. Apply to all the code on Hackage.
Current hacker(s): conal
Graphics
Fast general, pure-Haskell image synthesis (speed of Pan or Pajama but via ghc). Use Harpy or a new hs-plugins.
Current hacker(s): conal
General dependency tracking & updating
Simple, general dependency tracking & execution formulated as an applicative functor and using DataDriven computation. Applies uniformly to recompiling, re-executing, installing, compiler-recompiling, GUI specification and execution, etc. For compilation, it can give more precise (efficient) recompilation than language-specific tools (e.g., hmake and ghc --make) without being language-specific. Yields a continuous build system for free. No "make" info required (since inferred by construction). (Nontrivial language changes/improvements may be necessary.)
