I've been trying to learn Iteratee IO. I've made some progress by studying
John Millikin's examples in the source of the enumerator package.
I was surprised how confusing I found the tutorials that are available. I
think that it is primarily because of the lack of concrete examples. It

Hi,
Examples are very helpful to me too -- thank you for sharing. I'm especially
curious to see if there are any examples that allow you to use or convert
non-iteratee-based functions. I have only just begun reading about iteratees
and might be missing the point, but it seems like many of the

Announcing the Hackage release of two new versions[1,2] of the random-
fu package:
Version 0.1.4 is a build-fix release that extends support of the 0.1
API to GHC 7.
Version 0.2 is a significantly restructured version of the package.
Its API is mostly the same as the old for end users,

Hello all,
I am experiencing some issues to do my course task in university.
I have to write a calculator- function in Haskell. The function
argument is a list of strings and also form such list, as each string
of the argument made definite action:

What have you tried to do in order to make it work for the list, and what error
results? What is confusing about the error message? More generally, how could
you transform an operation on a single string into one that does the same thing
to a list of strings? You've probably talked about higher
I found the library myself, and i already put the code in that site:

parse :: [a] - [a]
parse [] = []
parse (x:xs) = eval (x:xs)

that it uses EOF (sentinel) so that it can sort the

However, the big-O complexity is the same.

That does not look like a GHC error message (the only compiler I'm familiar
with), but it seems like it is saying that you should not have the extra
