Hello, In case anyone is wondering this does not compile on vanilla Mac OS 10.6 because XCode 3.2 doesn't support C++11. I believe that XCode 4.2 does support it however I've not yet paid Apple the $100 they want before I can download it for 10.6. Macports has more recent versions of GCC however this option turned out to be fraught with difficulties[1][2]. Has anybody got HsQML working with XCode 4.2?

Dear All,

I would like to announce a new package called 'hsqml' [1].

HsQML provides a Haskell binding to the Qt Quick framework. It allows you to write graphical applications where the front-end is written in Qt Quick's QML language (incorporating JavaScript) and the back-end is written in Haskell. The two layers are coupled together via a facility to define custom JavaScript objects through which QML code can call into Haskell.

HsQML requires an installation of Qt 4.7 (including QtDeclarative) or later on your path. It has been tested with GHC 7.4 on both Linux and Windows.

There is also a simple example program available using HsQML on Hackage called 'hsqml-morris'. It implements a human v computer game of Nine Men's Morris with game logic and AI written in Haskell and the presentation layer in QML.

The library is currently limited by a lack of support for Qt signals, so calls can only be made from JavaScript to Haskell and not the other way. I plan to add support for these in a future release. Migration over to Qt 5.x is also likely once it's released.
