I want some simple CI for a small dev setup. Two motivations -- a full build takes some time, and an anticipated testsuite will also take some time. I really would rather not dive headfirst into one of the big players that require a java application container or whatever to show fancy graphs with multiple colors and etc. I'd be interested in something "culturally" Haskellish in particular -- preferably command line interaction or config files, and interop with Darcs is the absolute must.
Do any such tools exist, or am I stuck with one of the big players or writing my own?
Speaking of which, I recall that there's a build farm set up for GHC. Looking at it, I notice that it used to use buildbot and now uses a custom builder. Although those are set up for a different workflow, would either of them be a simpler, more straightforward solution?
Edit: I'm going with buildbot for now. Will update with how it works out.
Edit2: Ben Lippmeier has put buildbox on hackage, which also seems to be the foundation for a native Haskell CI solution. It is currently underdocumented, and probably not feature complete for my needs, but here it is: http://hackage.haskell.org/package/buildbox. He's used it to write a buildbot for repa: http://code.haskell.org/repa/repa-head/repa-bot/.
