Announcing Djinn, version 2004-12-11, a coding wizard
by Lennart Augustsson 07 Apr '11

07 Apr '11

Howdy, y'all! I've written a small program that takes a (Haskell) type and gives you back a function of that type if one exists. It's kind of fun, so I thought I'd share it. It's probably best explained with a sample session. calvin% djinn Welcome to Djinn version 2005-12-11. Type :h to get help. # Djinn is interactive if not given any arguments. # Let's see if it can find the identity function. Djinn> f ? a->a f :: a -> a f x1 = x1 # Yes, that was easy. Let's try some tuple munging. Djinn> sel ? ((a,b),(c,d)) -> (b,c) sel :: ((a, b), (c, d)) -> (b, c) sel ((_, v5), (v6, _)) = (v5, v6) # We can ask for the impossible, but then we get what we # deserve. Djinn> cast ? a->b -- cast cannot be realized. # OK, let's be bold and try some functions that are tricky to write: # return, bind, and callCC in the continuation monad Djinn> type C a = (a -> r) -> r Djinn> returnC ? a -> C a returnC :: a -> C a returnC x1 x2 = x2 x1 Djinn> bindC ? C a -> (a -> C b) -> C b bindC :: C a -> (a -> C b) -> C b bindC x1 x2 x3 = x1 (\ c15 -> x2 c15 (\ c17 -> x3 c17)) Djinn> callCC ? ((a -> C b) -> C a) -> C a callCC :: ((a -> C b) -> C a) -> C a callCC x1 x2 = x1 (\ c15 _ -> x2 c15) (\ c11 -> x2 c11) # Well, poor Djinn has a sweaty brow after deducing the code # for callCC so we had better quit. Djinn> :q Bye. To play with Djinn do a darcs get http://darcs.augustsson.net/Darcs/Djinn or get http://darcs.augustsson.net/Darcs/Djinn/Djinn.tar.gz Then just type make. (You need a Haskell 98 implementation and some libraries.) And then start djinn. For the curious, Djinn uses a decision procedure for intuitionistic propositional calculus due to Roy Dyckhoff. It's a variation of Gentzen's LJ system. This means that (in theory) Djinn will always find a function if one exists, and if one doesn't exist Djinn will terminate telling you so. This is the very first version, so expect bugs. :) Share and enjoy. -- Lennart

--------------------------------------------------------------------------- Haskell Weekly News http://sequence.complete.org/hwn/20091031 Issue 137 - October 31, 2009 --------------------------------------------------------------------------- Welcome to issue 137 of HWN, a newsletter covering developments in the [1]Haskell community. This week brings a new release of xmonad, some cool bindings to allow interaction with GNOME, KDE, and XFCE desktops and a new version of haskell-mode for the lesser of two editors... Some progress has also been made on the new HWN software, though this was mitigated by the fact that I started playing with the Isabelle theorem prover (after reading about Haskabelle) and so now I find myself convinced I should formally prove all of my software, and also that I'm pretty much incapable of getting things done when cool tools present themselves. In fact, I don't think I'll even be able to finish this [2]editori* [3]Exception: The Haskell Weekly News! Announcements xmonad 0.9 is now available! Don Stewart [4]announced a new version of everyone's favorite Tiling Window Manager, xmonad! The changes and improvments are too numerous to mention, see the post for details!

Pablo Nogueira [5]announced a second call for papers for the Workshop on Functional and Constraint Logic Programming. dbus-core 0.5 and dbus-client 0.1. John Millikin [6]announced pure-Haskell client libraries for using the D-Bus protocol. D-Bus is heavily used for inter-application IPC on Free and open-source desktop platforms, such as Linux, OpenSolaris, and FreeBSD. These libraries allow applications written in Haskell to inter-operate with other components of recent GNOME, KDE, and XFCE desktops. Singapore Functional Programmer Group First Meetup.

ANNOUNCE: dbus-core 0.5 and dbus-client 0.1
by John Millikin 30 Oct '09

30 Oct '09

These are pure-Haskell client libraries for using the D-Bus protocol. D-Bus is heavily used for inter-application IPC on Free and open-source desktop platforms, such as Linux, OpenSolaris, and FreeBSD. These libraries allow applications written in Haskell to inter-operate with other components of recent GNOME, KDE, and XFCE desktops. This is the first "real" release of these libraries; dbus-core has been published on Hackage for some time, but mostly just to make sure I got the Cabal bits right. I feel they are now stable / featureful enough for public use. Both are available on Hackage: http://hackage.haskell.org/package/dbus-core http://hackage.haskell.org/package/dbus-client --------- "dbus-core" is an implementation of the D-Bus protocol, specifically the parts relevant to clients. Eventually, it will probably grow some functions useful for implementing a message bus as well. It includes type mapping / conversion, an implementation of the wire format (marshaling / unmarshaling), data types for the currently defined message types (METHOD_CALL, METHOD_RETURN, ERROR, and SIGNAL) and a basic parser / generator for introspection documents. It is roughly equivalent in purpose to libdbus. By itself, a protocol implementation is somewhat cumbersome to use, so "dbus-client" is a high-level wrapper. It provides some abstractions like remote object proxies, exported object trees, synchronous method calls, signal reception, and name reservation. Messages are received and processed in separate IO threads, allowing asynchronous method call and signal handling. The purpose between splitting the library into two packages is stability; "dbus-core", ideally, will change only rarely -- performance improvements, new message / data types, etc. It provides a base level of functionality which more specialised libraries may use. "dbus-client" is an example of what such a library could look like, though for now it's not very Haskell-y (IO everywhere, exceptions, explicit locking). By separating the protocol from the client libs, alternative client libs can safely depend on the protocol implementation. --------- To see a sample of the library working, there's a clone of the "dbus-monitor" utility in <dbus-core/Examples>. Documentation is currently a bit lacking, so for now, the best documentation is the PDF of the source code itself, and the (rather barren) Haddock output: https://dl.getdropbox.com/u/1947532/dbus-core_0.5.pdf https://dl.getdropbox.com/u/1947532/dbus-core_0.5/index.html https://dl.getdropbox.com/u/1947532/dbus-client_0.1.pdf https://dl.getdropbox.com/u/1947532/dbus-client_0.1/index.html Once more people have used it without any major API issues, I'll write up a manual and populate the Haddock entries. Please respond with any feedback, difficulties, or suggestions. I'm particularly interested in ways to improve the public API, since I would rather make any breaking changes *before* anything big depends on these libraries.

ANNOUNCE: regular-0.2 and regular-extras-0.1
by José Pedro Magalhães 28 Oct '09

28 Oct '09

Hello all, I'm pleased to announce a new version of the regular library which provides generic programming with fixed points for regular datatypes. Many generic programs require information about the recursive positions of a datatype. Examples include the generic fold, generic rewriting, and the Zipper data structure. This approach provides a fixed point view on data which allows these definitions for regular datatypes. It can be seen as a simplification of the Multirec library, which provides similar functionality but for families of (possibly mutually recursive) datatypes. This library is the underlying generic representation mechanism in the paper: Thomas van Noort, Alexey Rodriguez, Stefan Holdermans, Johan Jeuring, Bastiaan Heeren. A Lightweight Approach to Datatype-Generic Rewriting. In Ralf Hinze and Don Syme, editors, Proceedings of the ACM SIGPLAN Workshop on Generic Programming, WGP 2008, Victoria, BC, Canada, September 20, 2008, pages 13–24. ACM Press, 2008. http://people.cs.uu.nl/stefan/pubs/noort08lightweight.html More information is available on the webpage: http://www.cs.uu.nl/wiki/GenericProgramming/Regular Additionally, we have also released a regular-extras package which provides more generic functions operating on the fixed point view provided by regular. Currently the functions provided are: * QuickCheck's arbitrary, with an option to provide size, and frequencies for each constructor; * QuickCheck's coarbitrary; * Data.Binary get and put. Features -------- * A simple library with a fixed point view * Includes detailed examples, such as the generic fold * Forms the basis for a generic rewriting library: http://hackage.haskell.org/package/rewriting * In its current form, this library does not support nested datatypes. Support to access parameters of a datatype is limited. Requirements ------------ * GHC 6.10.1 or later * Cabal 1.2.1 or later Download -------- With cabal-install: cabal install regular cabal install regular-extras Get the packages: http://hackage.haskell.org/package/regular http://hackage.haskell.org/package/regular-extras Get the source: svn checkout https://subversion.cs.uu.nl/repos/project.dgp-haskell.libraries/regular/ svn checkout https://subversion.cs.uu.nl/repos/project.dgp-haskell.libraries/regular-ext… Bugs & Support -------------- Report issues, request features, or just discuss the library with the authors, maintainers, and other interested persons at: http://www.haskell.org/mailman/listinfo/generics Pedro

Re: [Haskell-cafe] Is there a way to embed a Haskell interpreter/compiler in a browser. I think this would be a safer language than JavaScript.
by Kyle Murphy 27 Oct '09

27 Oct '09

I think it also depends on what exactly you're trying to do. If you're trying to do client side scripting using Haskell (much the way JS is used currently), that is including a Haskell "script" from some page that's intended to be executed on the client, you can't really do that. As Mathijs pointed out there are some projects that can let you use Haskell to generate JavaScript which provides a reasonable measure of safety (in much the same way that the final binary generated from Haskell is still safe even though machine code itself isn't), although isn't exactly the same thing. If all you want to do is execute some Haskell code inside of the browser process you could always us FFI to use the C plugin hooks to create a Haskell based plugin. Doing that and using something like hint you could even embed a Haskell "interpreter" inside of the browser, but of course you couldn't rely on something like that being available on any browser except your own. -R.
