Maybe permutation trees are a viable starting point?
See the paper Parsing Permutation Phrases which appears to be on CiteSeer.
Some slides are also here - the data type definitions and Functor
instance for permutation trees are on page 18 (pdf index page 19):

Maybe you could check out the FTGL package for inspiration on using
the freetype as a conventional C library. I was going to try to write
a Hackage package but realised I know nothing about typography and had
to start reading the intro. on Freetype's homepage (which is pretty
good, actually).
Dear Haskell-Cafe list,
Since I am learning Haskell, I decided to try to do a real program, to
practice and give me some experience. I choose to do a basic
typesetting program (like TeX/LaTeX). Now, obviously, such a program
needs to manipulate font objects, and in particular, font metrics.

Hi Gery
There probably isn't a library to help - I've looked at extracting
TrueType font metrics myself but abandoned it - TrueType fonts have a
very complicated file format, and the spec is inadequate to code an
implementation. TeX font metrics are probably simpler but obviously
tied to TeX.

Hi Brandon
Even that's not simple - freetype is essentially a framework for
writing font processors rather than a conventional C library[*]. Saner
perhaps is to write a C program using freetype to do the exact job you
have in mind, then bind to your C program.
Best wishes

Hi everyone,
as probably most people I find the GUI part of any application to be the
hardest part.
It just occurred to me that I *could* write my wxHaskell desktop
application as a web app too.
When the app starts, a haskell web server start listening on localhost
port 8080 for example

I wrote a package to turn Hack applications into standalone apps using
Webkit. The code is available at
http://github.com/snoyberg/hack-handler-webkit. However, it's currently
Linux-only. However, if I was going to write a desktop app based on an HTML
GUI, I would bundle Webkit like this. It fixes
There are many SVG elements, of which only a few are valid as the
content of each other SVG elements.
SvgDocumentElement defines the allowed subset for the SVG document.
I want to generate a DList Char for all those sub-elements and
finally collapse them to one DList Char representing

thanks for your ideas so far.
I think you might be looking for too much sugar. I don't know much
about your problem, but I would use approximately your approach and be
straightforward:

Ohhh...
SVG is a truly horrible format though, that almost completely
disguises the fact you are working with geometry. Being rude about the
designers, its as if they realized half way through the job that
putting a function-free PostScript into angle brackets was far too
verbose, so they added
I'd strongly recommend you simply choose a set of geometric objects
paths, polygons, whatever... and work with those, only considering SVG

Hi,
i am not quite sure how to do this in the most elegant way:
I have some data structures:
data A = A Double
data B = B Double
data C = C Double
...
and i want to allow only a subset in another data structure, so i did something
like this:
data SubSet = SubSetA A | SubSetC C
and use it
