[Haskell] ANN: universe-0.1
Thanks to all for the very interesting feedback! Your suggestions have resulted in a second release of universe. New in this release: * instances of Universe and Finite for function spaces * some cheeky, optional instances of Eq, Ord, Show, and Read for functions with Finite domains * support for (some) Representable functors * ...but the downside is that this release now relies on TypeFamilies (let me know if this seems like a showstopper for you) Enjoy, and keep the complaints coming! ~d Quoting wagne...@seas.upenn.edu: I've long heralded "data-default" as my favorite ten-line package... before it was released, I found my self writing those a few lines in each project to do just what's done there. Inspired by this, and the fact that there's a separate ten lines that I find myself writing in nearly every project, I'm pleased to announce the initial release of "universe". The package sports just two load-bearing lines: class Universe a where universe :: [a] class Universe a => Finite a where universeF :: [a] ...along with a dozen or so instances of each. The instance do nothing more than enumerating all the values of the given type. Hope you enjoy it, and let me know if you think there are some important missing instances! http://hackage.haskell.org/package/universe https://github.com/dmwit/universe ~d ___ Haskell mailing list Haskell@haskell.org http://www.haskell.org/mailman/listinfo/haskell ___ Haskell mailing list Haskell@haskell.org http://www.haskell.org/mailman/listinfo/haskell

[Haskell] [ANN] gtk2hs-0.12.4
Today, we welcome into the world version 0.12.4 of Gtk2Hs[1], a set of Haskell bindings to many of the libraries included in the Gtk+/Gnome platform. Gtk+ is an extensive and mature multi-platform toolkit for creating graphical user interfaces. GUIs written using Gtk2Hs use themes to resemble the native look on Windows. Gtk is the toolkit used by Gnome, one of the two major GUI toolkits on Linux. On Mac OS programs written using Gtk2Hs are run by Apple's X11 server but may also be linked against a native Aqua implementation of Gtk. This release is primarily a GHC-7.6 compatibility release, thanks in large part to John Lato. In addition to releases of the core packages, this release includes point updates to gconf and gstreamer. The release has been tested on Linux and Windows with a variety of combinations of Gtk+ and GHC versions. Installation Assuming you have the necessary Gtk+ base libraries already installed, you can get the basic set of Haskell bindings with these two commands: cabal install gtk2hs-buildtools cabal install gtk Other available packages include gconf, glade, gnomevfs, gstreamer, gtkglext, gtksourceview2, soegtk, svgcairo, vte, and webkit. There are longer-winded instructions that include pointers on getting the Gtk+ base libraries installed on the website [2]. Features * Automatic memory management (unlike some other C/C++ GUI libraries, Gtk+ provides proper support for garbage-collected languages) * Unicode support * High quality vector graphics using Cairo * Extensive reference documentation * An implementation of the ``Haskell School of Expression'' graphics API Community - You can keep up with the latest developments on the mailing lists: * gtk2hs-users [3]: discussions about writing code that uses Gtk2Hs * gtk2hs-devel [4]: discussions about modifying the Gtk2Hs bindings * gtk2hs-commit [5]: a read-only mailing list with announcements of every patch to hit the darcs repository Check out the latest code via darcs: darcs get http://code.haskell.org/gtk2hs/ Or complain on the bug tracker [6].

[Haskell] Reminder: HacPhi 2012 registration closing in two weeks
Hello all, HacPhi 2012 is drawing near! To help us finalize the arrangements, we plan on closing the registration period on Friday, July 20, 2012 at 1430 local time (local to you!) ...two weeks before the beginning of the festivities. If you plan on coming, please drop us a line so that we know how many people to provide food and wireless for (and we all know which of those two is the more important ;-). Full instructions for registering are available on the wiki page [1], as well as information about making hotel and travel arrangements. The HacPhi wiki [2] has full details, but the skinny is this: we kick off at 1430 on Friday, August 3, and will hack together for three days (until August 5), with breaks for food and sleep. We will have a time for short talks as well -- let us know if you're interested in telling us a bit about your latest exploits. Whether you're a raw recruit or a grizzled code veteran, come join your Haskell-y comrades-in-arms for a weekend of hacking and fun! - The HacPhi team Brent Yorgey (byorgey) Daniel Wagner (dmwit) Chris Casinghino (ccasin) [1] http://www.haskell.org/haskellwiki/Hac_%CF%86/Register [2] http://www.haskell.org/haskellwiki/Hac_%CF%86 ___ Haskell mailing list Haskell@haskell.org http://www.haskell.org/mailman/listinfo/haskell
[Haskell] ANN: yeganesh-2.5
Today heralds the release of version 2.5 of the venerable yeganesh[1] menu. The suckless team produces a small program named dmenu[2] which acts like a normal Unix pipe program, accepting input on stdin and producing output on stdout, with the one caveat that it sticks the user in between. It launches a very small menu, presenting the user with each of the lines of stdin as choices, and prints the chosen text as a single line to stdout. This is very convenient for lightweight, GUI-less programs and scripts that need some minimal interaction; however, it is completely memoryless. Yeganesh wraps dmenu to add some memory: it records which choices the user has made in the past, and promotes popular choices to the front of the menu on future runs. See the website[1] for screenshots. New in this release: * Switching away from Read as the cache file parser reduced startup time by a factor of eight. (Caches in the old format will be transparently upgraded.) * When running in --executables mode, broken symlinks no longer sabotage their siblings in the filesystem tree. * Minor change to command-line parsing to preserve consistency with GNU-style command lines. (Any command line that used to work will still work, and will behave the same; however, some lines that were rejected before are now accepted and passed on to dmenu.) To try it out: 1. Install dmenu via your package manager, or from source (it's quite small!). wget http://dl.suckless.org/tools/dmenu-4.5.tar.gz tar xf dmenu-4.5.tar.gz cd dmenu-4.5 make install 2. Install yeganesh from Hackage. cabal install yeganesh 3. Run yeganesh; for example, to choose a file in your current directory, then see that file float to the top of your choices, try ls | yeganesh ls | yeganesh Features: * One common use case for choosing an executable from your $PATH to launch; yeganesh will scan your $PATH for you when launched in the --executables mode. * Multiple popularity profiles allow separate dmenu consumers to have separate memories. (For example, I have separate profiles for launching GUI and shell programs.) * Sometimes you say something embarassing; use the --filter mode to forget it. Enjoy! ~d [1] http://dmwit.com/yeganesh [2] http://tools.suckless.org/dmenu/ ___ Haskell mailing list Haskell@haskell.org http://www.haskell.org/mailman/listinfo/haskell
