Hello all,
Does anyone favourite technique to track down an undefined call? I'm
99% sure that my code is not the offender (I've grepped for undefined
occurrences and turned them all into error calls). Supposing that
this is happening in some other package or library that I'm using,
what is the

Hi Jeroen,
I've done this. I didn't use the stuff from gtk-osx.org, but rather
from the imendio site itself. I'm not sure how it would work with
binary package they now provide, but if you use their jhbuild scripts
you get something usable. It's ugly, but it works for compiled gtk2hs
programs. If
Hello all,
I'm new to haskell and was just wondering if there was any efficient
or standard way to store and modify some sort of state data. The
functional nature of haskell has me confused in this respect! Basically
what I want to achieve is an interactive program that allows you to edit

Mmm, yes I had thought of that. But I wasn't sure how it would work, as
you can't have variables in the same sense as imperative languages. So
if I create a mainloop sort of
Hello all,
I've recently attempted to get the gtk+hs bindings operational, with
evidently no success. They both compile fine, but when trying to make
all the examples in the gtk+hs tree, it gives up with:
/usr/local/lib/c2hs-0.12.0/ghc6/libc2hs.a(C2HS.o)(.text+0x32): In

Hello all,
Just got an interesting error, which I can't really understand (but that DOES
happen a lot...). Trying to work with existention types, record types, and wrapping
the whole thing up in a nice IORef for my uses:
data ETable = forall a. EditableTable a = ETable a
data GuiRecord
Hello all,
Given an HList (http://homepages.cwi.nl/~ralf/HList/) would it be
possible to do the following:
Create a class/function/magicks that would essentially do what
hOccursMany does, except it would not return a list of elements, but a
new HList. For example, would this allow us to be able
Hello all,
Looking at the OOHaskell black (grey?) magic, and wondering if there
would be an interesting way to construct class interfaces using the
OOHaskell paradigm?
I'm trying to do it as so (assume relevant types/proxies declared):
type FigureInter = Record ( Draw :=: IO ()
, but is there a nice way to get around it?
I think I could wrap them up in a datatype (ie, data InterOne =
InterOne Inter1, and modify definitions accordingly) but are there any
alternative methods?

Hello all,
Does anyone have any experience with using large-ish (20 element)
OOHaskell records? I'm finding that as the records get large, compile
times get fairly ridiculous. Is there some explicit typing I should be
doing to help the type-checker?
Thanks!
Scott
