Conal, myself, and a few others are working on FieldTrip http://www.haskell.org/haskellwiki/FieldTrip A library that is built onto of OpenGL. Early days, but we certainly use OpenGL. Technically, the final version will be independent of OpenGL, but use OpenGL for rendering. But that a critical piece of the library offering!

Fw: patch applied (ghc): Remove the OpenGL family of libraries fromextralibs
by Claus Reinke 28 Jul '08

FYI: Haskell's OpenGL binding has just been dropped from GHC's extralibs, which means that it will no longer be kept in sync with GHC development, at least not by GHC HQ. GHC HQ has its hands full and -generally speaking - extralibs are to be replaced by H(L)P, the Haskell (Library) Platform: http://haskell.org/haskellwiki/Haskell_Platform so this part is understandable. But OpenGL has been dropped before H(L)P is ready to take over from extralibs, and at the recent GHC Irc meeting on the topic http://hackage.haskell.org/trac/ghc/attachment/wiki/IRC_Meetings/ghc-2008-0… the mood seemed to favour not including OpenGL&co in the initial versions of H(L)P. Sven put a lot of good work into these libraries, but he is often not around for a long time, and it would be a shame if these gems were orphaned and went out of sync in the meantime. While I haven't used OpenGL in a while, I've always hoped to come back to that, not to mention Sven's spatial audio binding additions. And if I'm not mistaken, there are other community members who are using these libs right now for research, possibly even prototyping in connection with a startup? So, if one of you wanted to step forward and offer to keep these Haskell bindings for OpenGL&co maintained, perhaps steward them into the H(L)P, now would probably be a good time.

Yes, same here; don't worry, it's not going away. It would be nice to know, though, how many people are using it and what they're using it for. I'm using it for information visualization, and slowly evolving/cribbing together something like the Processing (http://www.processing.org) framework for Haskell as I do more things.

Some people post the funniest rumours as if they were facts. $ ghc-pkg field OpenGL maintainer maintainer: sven.panne(a)aedion.de At the end of this message, I also append the output of darcs changes since OpenGL 2.1 was supported, for those interested in what might be involved in maintainance: Fri Nov 10 10:14:54 GMT Standard Time 2006 sven.panne(a)aedion.de * Updated Haddock module headers (now OpenGL 2.1 support, API is stable) It just so happens that the library is very stable (unlike other libraries I could think of;-) - Sven's last bug-fix patch was in March 2007, the patches since then have been build system evolution/maintainance. So the problem is not with the library, but with the environment - since its creation, the library has seen FFI tools appear and disappear, FFI spec and library hierarchy take shape, darcs appear and be taken on, Cabal appear and be taken on, packages and tools move on, split up, change their API, etc. - thanks to Sven and others, the binding has weathered all that, without making a lot of noise. And now, there is another enviroment change, with extralibs going and the Haskell Platform aiming to improve the Haskell installation experience. And new quality criteria will be prescribed that this old library will have to meet to be allowed in with the new kids on the block. > The only change is that the GHC developers don't put them in a tarball > on haskell.org/ghc prior to releasing GHC itself. It isn't the tarballing, it is (a) whether the library is run in the HEAD buildbots to flush out breaking changes to the environment early (b) whether enviroment changes are reflected in the library to unbreak its build before user installations are affected (c) whether the library can be relied on as being available on default Haskell installations (this would seem to be less of a problem with Cabal/hackage and user installs, but not all clients have install privileges/tools - OpenGL building uses configure, which in itself might not be installed on Windows; and in some University contexts, installation for public PCs is on a centralised, yearly basis, not per student; etc.; adding the GLUT dll has been a popular request ever since GHC had Windows installers, meaning that every single time someone forgets to put that dll in the installer, someone has reported it as a bug/feature request) I'm not aware of any urgent breakage in the OpenGL binding, nor is the current source going away, and as Duncan says, he expects OpenGL to reappear in the Haskell Platform later on. But neither do I believe the rumour that OpenGL isn't much used, and forwarding the removal notice gives those users the opportunity to speak up now if they prefer no gaps in OpenGL presence, or forever to hold their peace, as they say. Unless Sven wants to do the job himself, a maintainer would mainly have to adapt the library to the Haskell Platform criteria, keep up with the forever changing build environments, and counter rumours about the OpenGL binding being unmaintained or unused.

Well, since HOpenGL seems to support practically all of OpenGL 2.1, I don't see that there's much to maintain, except compatibility with upcoming releases of GHC and possibly some optimization. Maybe I'm missing something, though. Is there a list of outstanding bugs somewhere? I personally know of one bug that I found some time ago, which I simply worked around, but a comprehensive list, I'm not aware of. -- Jeff On Fri, Jul 25, 2008 at 1:27 PM, Don Stewart <dons(a)galois.com> wrote: > claus.reinke: >> FYI: Haskell's OpenGL binding has just been dropped from GHC's >> extralibs, which means that it will no longer be kept in sync with GHC >> development, at least not by GHC HQ. >> >> GHC HQ has its hands full and -generally speaking - extralibs are to >> be replaced by H(L)P, the Haskell (Library) Platform: >> >> http://haskell.org/haskellwiki/Haskell_Platform >> >> so this part is understandable.
