Hi, I recently wanted to poke around at Cairo and noticed it was only available as part of gtk2hs. It seemed to me Cairo ought to be a separate library so I made an attempt at splitting Cairo out of the gtk2hs build. While I was at it, I converted the build to just Cabal, which means it'd also be available via cabal-get. This involved converting the Cairo-specific code to use the upstream c2hs among other changes.
My questions for you: - Does this plan in general seem desirable to you? In theory, Cairo can be built against other targets (like in this open issue: http://hackage.haskell.org/trac/gtk2hs/ticket/1180) and I guess having an independent build could make adding those easier. - Where can/should I host the independent Cairo package? - Do you really care about supporting GTK versions older than 2.8 anymore? I found while looking through the gtk2hs build that a lot of the complexity is supporting what seems to me to be obsolete configurations. - How can I test that this change actually works? I've attached my patch (minus the patch that just rm -r's the "cairo" subdir of the gtk2hs distribution) that *seems* to work, but I probably overlooked some pieces. If this general idea looks good to you, I'd like advice on how to better get this ready in a state to commit. (E.g. one huge patch? Multiple patches? I'm not too good with darcs...) Hopefully this could be the first step in a larger process, which would be to split all of the independent libraries out of gtk2hs. For example, I could see pulling "svgcairo" library out into its own package as well, probably renaming it to an rsvg binding (since that's really what it is) in the process.
