Hello all,
It seems like getDirectoryContents applies codepage conversion based
on the default program locale under Windows. What this means is that
if my default codepage is some kind of Latin, Asian glyphs get
returned as '?' in the filename. By '?' I don't mean that the font is
lacking the glyp

Your best bet would be to start with these instances in HSH.Command:

Hi,
I am learning to use cabal for my code.
Just when I start, I met a question, is there an easy way to find
out what packages my code depends?

No; at least not automatically. The idea is that a function that is

As others have said, there are cases where non-strictness is what you
want. And if you are using a type that is stri
Inspired by the CLI utility "unp", which was nice but lacked some DWIM

it's easier). It automagically calls the right "unpacker" program for
you and works on both files and directories:

You can make numeric class instances from arbitrary Applicatives [1]. I
imagine a lot of them (e.g. Stream) would want at least some
non-strictness. We might provide strict alternatives for sum and product.
I wonder what else.

Calling foreign functions that return values is problematic for the
compiler -- I haven't invested enough time to come up with a good
solution.
The work around is to assign the result to an external variable. The
drawback is the result will not be available until the rule executing
the action has

That's an interesting example. I guess a lazy number system like that
would work nicely for Deniz's use case.

John,
Thanks for the reply.
In this case, would the body of my function run in a separate thread
via forkProcess (that's what is needed, maybe I didn't make it clear)?
In my previous project, I had to do like this (probably not very
portable, at least requires System.Posix):

hi there,
I've been working with haskell and atom dsl, however I'm new to haskell..
John Van Enk inspired me with programming arduino->atmegas , with haskell,
So here is my problem.
With an action , action :: ([String] -> String) -> [UE] -> Atom () ,
it's possible make calls to some precoded C fun
