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:
$ ./hnop
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.

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.

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

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.

Just out of curiosity, did you try "wc -l"?

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 w
10 matches
