Hi,
I just read an article (sorry, it is in russian:

in big citied developers complain that nothing happens at their
location, but when you try to make an event -- only few of them want to

I never participate in

Left immediately. So,
throwError in enumerator can't be caught. Is it correct?
Then it seems to be a design bug in websockets -- it is not possible to
know from the WebSockets monad that client closed connection.

Hi,
websockets package has basic support for client-side applications:
http://hackage.haskell.org/packages/archive/websockets/0.7.2.1/doc/html/Network-WebSockets.html#g:12
AFAIK it is the only available option right now (except implementing it
yourself.)

Hello,
I uploaded new release of bindings-gobject,
low level binding to gobject library:
http://hackage.haskell.org/package/bindings-gobject-0.4
(I maintain it now)
Now it exposes internals of GObject and GObjectClass,
so it is possible to create custom GObject subclasses
from haskell land.

Hi,
shuffle :: int - [a] - [a]
shuffle i [cards] = ...
So 'cards' is of type 'a' :
cards :: a
... = (cards!!i)
So 'cards' is a list of something:
cards :: [b]
... = (cards!!i) + ...
(+) :: b - b - b,
the result of the 'shuffle' should be of type [a], so
b :: [a],
cards :: [[a]]

Hello
First of all, sorry my pure english...
My aim was to prove that haskell GUI library can be:
- pure: does not use any kind of mutable variables
- statically typed: does not use existential types, Data.Dynamic, etc.
- easy to use: simple things should be simple
- easy to extend:
