Re: [Haskell-cafe] Poll plea: State of GUI graphics libraries in Haskell
John Lato jwl...@gmail.com writes: QT - never tried this, but my impression is the Haskell-QT bindings are a bit stale Yes, QtHaskell [1] has been inactive for three years, as far as I can tell. However, there are newish bindings [2] for the Qt Quick declarative UI stuff that's appeared in recent Qt versions -- see the package hsqml on hackage [3]. It hasn't had any new uploads to hackage since last year, but there was activity on its repo as recently as yesterday [4]. I've yet to see any applications built on it, but it looks exciting. -Keshav [1] http://qthaskell.berlios.de/ [2] http://www.gekkou.co.uk/software/hsqml/ [3] http://hackage.haskell.org/package/hsqml [4] http://patch-tag.com/r/komadori/HsQML/snapshots/all/history ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe

Robin KAY komad...@gekkou.co.uk writes: Yes, I'm afraid I've been failing to embrace the release early release often mantra with HsQML. I originally set myself some (fairly modest) goals for the next release. Unfortunately, I've had less time to spend on it than I'd like and it's delayed getting there. There has been a fair amount of interest via e-mail, but the dearth of releases has probably dissuaded people from using it. Also, I need to write more documentation and provide better examples. That said, I've got a ticket to the Haskell eXchange in London next month and I set myself a personal deadline of making a new release before then. So, having said that in public, I'll have to really try and keep to it ^_^'! The next release will add support for Qt signals, plus bug fixes and Mac support. For the next release after that, I plan to port the library to Qt 5. Awesome!

Re: [Haskell-cafe] list comprehension doesn't work
Danny Gratzer danny.grat...@gmail.com writes: But this still doesn't really work since it'll loop forever without finding any solutions. Haskell's list comprehensions don't play very nicely with multiple infinite lists. If you really want to use this style of programming for your problem, have a look at the logict package on Hackage, it has functions designed to solve the problem of multiple infinite choices. See also the control-monad-omega package. -Keshav ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
