Haskell projects for Google's Summer of Code.
Please refer to the new trac-based site at <http://hackage.haskell.org/trac/summer-of-code/>.
This page is for mentors to add their ideas and to say which projects they'd be happy to supervise. It is also for students to see what kinds of projects are available. Students should not claim projects here however, but use the normal Google SoC application process. Mentors feel free to write your name under orphaned projects.
== Cabal-get/HackageDB ==
Cabal-get is an automatic installer for Cabal libraries.
The goal is to distribute the program with [http://haskell.org/cabal Cabal], but to achieve this we need to cut almost all of its dependencies. This project should be fairly easy (the code base of cabal-get is only 1K loc).
Mentor: Lemmih (lemmih@gmail.com)
== GhcPlugins ==
Write a new plugin system using the new ghc-api. Enough of the groundwork has been laid out now that someone with a few months and some background could finish up the work.
GhcPlugins will replace the plugin system currently used in [http://haskell.org/hide hIDE].
Mentor: Lemmih (lemmih@gmail.com)
== Fix HsSDL (Haskell [http://libsdl.org libSDL] bindings) on Windows and MacOS ==
== Implement various debugging tools in GHC ==
* Dynamic breakpoints.
* Generic object viewer.
* Simple CCS for providing stack traces on exceptions and breakpoints.
Mentor: Lemmih (lemmih@gmail.com)
== Handle recursive modules in GHC ==
== Gtk / Graphics / GNOME related projects ==
I'd be happy to accept projects in this area. Last year I was unoficial mentor to Paolo who did the [http://www.cairographics.org/ cairo] bindings. Possible ideas include a [http://www.freedesktop.org/wiki/Software/dbus dbus] binding. (Feel free to add more ideas here or I might do as I think of them.)
Mentor: Duncan Coutts
== Incremental GC for GHC ==
Implementing the incremental garbage collection algorithm described in the paper [http://research.microsoft.com/~simonpj/Papers/inc-gc.htm Non-stop Haskell] in GHC.
== hs-plugins based web server ==
Build an industrial-strength CGI/FastCGI/etc daemon to be used for enterprise-type web applications.
HSP does have the hs-plugins part. So do new versions of WASH. In HAppS the enterprise part is keeping us away from hs-plugins, if it were for research only there would be hs-plugins support (4-8 hours of work).
== Continuation based DSL on top of HAppS ==
Do you have a vision how to do better than WASH? Integrate continuation based interaction with client or use something like Functional Forms for the interaction. How to best to interact with XML etc. Other HAppS related projects
also possible.
Mentor: Einar Karttunen (musasabi)
== Parsers for various programming languages ==
Populate the [http://haskell.org/ghc/docs/latest/html/libraries/index.html Language] hierarchy of modules with new parsers for many languages, at the moment it does only contain Language.Haskell.
Mentor: Shae Matijs Erisson (shapr)
== Yi projects ==
Syntax Highlighting, Plugins. It's quite a peculiar kind of application. Its design is based on [http://www.cse.unsw.edu.au/~dons/papers/PSSC04.html type-safe dynamically loadable modules] and it is [http://www.cse.unsw.edu.au/~dons/papers/PSSC04.html more dynamic than Emacs]!
Mentor: Shae Matijs Erisson (shapr)
== Students' ideas / Game ==
I'm ready to take on anyone willing to write a useful application or game (preferably a program) given that it is of reasonable size (upper limitaton).
Mentor: Johan Henriksson (Mahogny)
== Bioinformatics tools ==
1. Further develop RBR, a tool for masking repeats. This can include
a) optimize (using FastPackedString and/or a new internal data structure); b) extend functionality.
2. Develop a tool for annotation/classification of sequences. This would involve computation on and visualization of graphs (experience with the latter would be really great).
Prior bioinformatics knowledge is not a requirement. Please contact me for details.
Mentor: Ketil ([mailto:ketil@ii.uib.no ketil@ii.uib.no])
== Concurrent disk-based data structures ==
Implement B+tree or a variant supporting concurrent updates using STM,
serialize updates into a write ahead log and provide for serialization.
Bind the whole thing with a nice HaskellDB like API. Variations on
the theme possible.
Mentor: Einar Karttunen
== Haskellnet ==
We have got cgi, ftp, http, and irc. Get them into shape in the hierarchical libraries as well as adding a number of other protocols, like nntp, smtp and pop3, imap4, ... much like the [http://ocamlnet.sourceforge.net/doc/goals/goals.html Ocamlnet project].
Mentor: Shae Matijs Erisson (shapr)
== Port ghc-api's eval mechanism to Yi ==
Yi is an editor written and extensible in Haskell. Construct a binding
to ghc-api such that new expressions may be evaluated at runtime in the
editor, accessing the editors internal structures in a type safe way,
dynamically. elisp for Haskell!
Mentor: Don Stewart (dons@cse.unsw.edu.au) and Lemmih (lemmih@gmail.com).
== Data.ByteString ==
Extend the [http://www.cse.unsw.edu.au/~dons/fps.html Data.ByteString]
interface to arbitrary (Storable a) arrays. Data.ByteString provides a
high performance api to arrays of bytes. Generalise this to arbitrary
vectors of Storable a values, winning fame and glory in the process.
Mentor: Don Stewart (dons@cse.unsw.edu.au)
== Unicode layer over Data.ByteString ==
Extend the [http://www.cse.unsw.edu.au/~dons/fps.html Data.ByteString]
interface to support Unicode.
Mentor: Don Stewart (dons@cse.unsw.edu.au)
== Generic Hide Hacking ==
* Rewrite plugins for the new plugin-system.
* Integration with [[Lambdabot]], access to plugins through Hide.
* Other?
Mentor: Don Stewart (dons@cse.unsw.edu.au), Lemmih (lemmih@gmail.com)
== A Haskell shell ==
Concise syntax and higher order functions would make a Haskell shell
very useful. This project would aim to produce a real world shell
written in Haskell, and using an embedded domain specific language to
encode common operations.
Mentor: Don Stewart (dons@cse.unsw.edu.au)
== Embed ghci/ghci-api in ion ==
[http://modeemi.cs.tut.fi/~tuomov/ion/ ion] is a cool window manager
written by Tuomo Valkonen, a Haskell hacker. It is currently extensible
in Ion, but a very interesting project would be to work out how to
dynamically extend it in Haskell, perhaps using ideas from
[http://www.cse.unsw.edu.au/~dons/yi.html Yi].
Mentor: Don Stewart (dons@cse.unsw.edu.au)
== Improve performance of numerical code ==
GHC's performance for double and float intensive code is not as good as
it could be. Find out why and improive it. Requires GHC backend hacking.
Must be very Haskell literate or have knowledge of code generators.
Mentor: Don Stewart (dons@cse.unsw.edu.au)
== Port the Clean high performance string code ==
Clean does very well for low level string benchmarks. Find out what
they do, and port it to [http://www.cse.unsw.edu.au/~dons/fps.html Data.ByteString]
Mentor: Don Stewart (dons@cse.unsw.edu.au)
== Frag hacking ==
[[Frag]] is a 3d first person shootup game written in Haskell,
using OpenGL. It can be greatly extended in all sorts of ways. If
you're in to gaming, have a look at this.
Mentor: Don Stewart (dons@cse.unsw.edu.au)
