Hi John,
NB
the essence what I am trying to do is to define a proxy class Foo for
class Ba1 I would have thought that something as simple as the
following would have worked ??
class Ba1 a where
dosomething :: a - IO ()
ba1 :: Ba1 a = a - IO ()
ba1 x = dosomething x
instance Ba1 Int
Just out of curiosity, did you try wc -l?

I have a bunch of data files where each line represents a data
point. It's nice to be able to quickly tell how many data points I
have. I had been using wc, like this:

No. I suppose man wc would have helped, but this has been entertaining, anyway.
Times for lc and wc -l seem comparable over a couple of runs. So in any
case, it's encouraging that it's so easy to reach speeds comparable to
(presumably) highly-tuned C code like this.

Haskell's expressiveness really shines here, doesn't it!

Wow. 64 times as fast for this run, with almost no effort on
my part. Granted, wc is doing more work, but the number of
words and characters aren't interesting to me in this case,
anyway. I can't imagine (implementation time)*(execution
time) being much shorter.
Well, the latest HDBC has been stable for quite awhile. I've used it in
a number of projects, and I know several others have as well.
I've made some minor tweaks to the cabal files to work with GHC 6.4.2,
and released it as 1.0.0.
Have fun.

Hello everyone,
I'm pleased to announce the first release of hpodder. hpodder is a
podcast downloader (podcatcher) written in pure Haskell. I wrote it
because I was unsatisfied with the other podcatchers for Linux.
I am using hpodder for my own purposes already.

HNOP: Haskell No Operation
A first version of HNOP 0.1 is now available under a simple permissive
license. This version should be considered beta quality, though I
don't know of any bugs.

HNOP does nothing. Here's a sample session to illustrate:

Hi,
I have written a System.FilePath module in part based on the one in
Yhc, and in part based on the one in Cabal (thanks to Lemmih). The aim
is to try and get this module into the base package, as FilePath's are
something many programs use, but its all too easy to hack up a little

Hi
1) there are two independent filepath modules used with little
modifications in all projects i seen. They both included in MissingH
(FilePath.hs and NameManip.hs).
From what I can tell, FilePath.hs is the one from Cabal, which I
already used as a reference. As far as I can tell, this
Then I should be thanking Duncan as well (thanks!). I had seen the array fusion idea before in the NDP work, but I hadn't thought of applying to this area. I wonder where else the concept might apply? Is there a typeclass to be built?
