| − | == 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 [http://gobby.0x539.de/trac/ 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) |
||
| − | |||
| − | == Shim == |
||
| − | |||
| − | Port shim to GHC 6.8 |
||
| − | |||
| − | Current hacker(s): beschmi (Benedikt Schmidt) |
||
| − | |||
| − | == 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): [[User:Conal|conal]] |
||
| − | |||
| − | == Data.Rope == |
||
| − | |||
| − | Port OCaml's ropes implementation to Haskell. |
||
| − | |||
| − | Current hacker(s): Johan Tibell (tibbe), Ivan (ivant) |
||
| − | |||
| − | == General composition tools == |
||
| − | |||
| − | === Type composition & related === |
||
| − | |||
| − | [[TypeCompose]]: some classes & instances for forms of type composition (including contravariant functors and applicative functors) |
||
| − | |||
| − | Current hacker(s): [[User:Conal|conal]] |
||
| − | |||
| − | === Deep arrows === |
||
| − | |||
| − | [[DeepArrow]]: a framework for composable "editors" of pure values |
||
| − | |||
| − | Current hacker(s): [[User:Conal|conal]] |
||
| − | |||
| − | == Source browsing == |
||
| − | |||
| − | [http://tiddlywiki.com 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): [[User:Conal|conal]] |
||
| − | |||
| − | == Graphics == |
||
| − | |||
| − | Fast general, pure-Haskell image synthesis (speed of [http://conal.net/Pan Pan] or [http://conal.net/Pajama Pajama] but via ghc). Use Harpy or a new hs-plugins. |
||
| − | |||
| − | Current hacker(s): [[User:Conal|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., <code>hmake</code> and <code>ghc --make</code>) 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.) |

| − | |||
| − | Current hacker(s): [[User:Conal|conal]] |
||
| − | |||
| − | == Backtraces in the GHCi debugger == |
||
| − | |||
| − | This has turned out to be really complicated, so look at [http://hackage.haskell.org/trac/ghc/wiki/LightweightCCSCallStack here] for the details. Sadly, Alexey stays only for the first day. |
||
| − | |||
| − | Current hackers: pepe, Alexey |
||
| − | |||
| − | == Coverage recording in the GHC testsuite == |
||
| − | |||
| − | We would like HPC coverage recording to be performed as a possible part of running the tests in the GHC testsuite. Code targeted by this could be the compiler code itself, the runtime system, the library code of a tested library, and the test code. |
||
| − | |||
| − | Current hackers: thorkilnaur |
||
| − | |||
| − | == Shim == |
||
| − | |||
| − | We still believe that Shim has a great potential to become an awesome IDE, and so we've decided to make it compatible with ghc 6.8 |
||
| − | |||

Generic Information
You can apply for an account and a project using the community server. 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
