Hi, all,
I have uploaded a utility program xournal-convert which is a
command-line utility for changing xournal file format to various other
formats. Currently, converting xournal file format (xoj) to several
SVG files for each page and index.html for navigating all those pages
are implemented. I

Hi Tim
More problematic is that FRP models hybrid (continuous and discrete)
systems. For me at least, MIDI seems essentially discrete - a stream
of control events. In MIDI files control events are twinned with a
time stamp so

If you're afraid of Yampa (I was ;p), Ertugrul Söylemez released recently
the Netwire http://hackage.haskell.org/package/netwire-3.1.0 library on
hackage.
I went through its internals and I find it simpler to grasp and to use than
Yampa as Ertugrul chose to replace the switch functions by the use
Hi Tim
Events in FRP / Yampa are typically key presses / mouse movement, so a
MIDI controller generating Note-on / Note-off events would be a direct
analogue to key presses.

systems. For me at least, MIDI seems essentially

Hi, Greg,
Sorry that I just missed to read your reply.
Since hxournal has a configuration file to specify input device and
also is activated on the toggle menu item Use X Input, you should be
able to experiment pen drawing now.
Did you succeed in using the latest version of hxournal?
I
yes it worked after your updates shortly after this. Thank you very much
for checking up, and also for continuing to develop this - I may be able to
replace xournal with it now.

Hi Haskellers!
I'm writing my first non-trivial Haskell application. I have an electronic
drum set that generates MIDI events that I process with Haskell. A simple
application of this kind might have fixed drums associated with fixed

One other little GHC 7.4 note. When I first tried building code with

A good compromise might be opa (not used it myself, but I've been
reading up on it as a possible candidate for any personal web projects
I might want to do). It is not haskell, but it is ML-derived, and
specifically for webapps. It has some example apps available, though
