After more than two decades using the C-family of languages
(C, C++, Java, C#, Perl, unix shells), I've been trying to learn
Haskell. Each time I've begun with enthusiasm, and eventually
run out of gas before I've gotten to writing real code. Haskell's
learning curve is not very steep, but it is very long.
I haven't yet gotten to the things I do the most, which all
involve side-effects: mostly actions on directories and files,
as well as calls to system utilities or other pieces of software.
I'm working my way through "Real Life Haskell" and watching
Erick Meijer's lectures, but I'm beginning to fear I'll run
out of gas again if I can't write some programs that touch
the real world.
Are there any tutorials or other material that will get me
going in that area?
thanks,
Kevin

I ran out of gas 4-5 times myself. Unfortunately I don't have an easy
answer.
I would recommend:
http://www.haskell.org/haskellwiki/Simple_unix_tools
https://www.fpcomplete.com/
http://learnyouahaskell.com/
as well as reading actual code from Haskell repositories on GitHub--and,
perhaps above all, to actually write programs--any kind of program. That,
more than anything, eventually makes all the abstract reading fall into
place.

See if you can find some interesting open-source Haskell projects that
involve the sort of "real-world" code you're interested in, and see if
you can fix some small bugs, improve the documentation, etc. That
will give you some practice writing real code, but it's ten times
easier if you don't have to start absolutely from scratch.

Kevin, I highly recommend you take a look at the Haskell from Scratch
video series by jekor:
http://www.youtube.com/user/jekor
He's currently writing "redo" in Haskell, which is a software build tool
similar to make. This means he's reading directory contents, reading
and writing files, and executing system calls. Sounds right up your
alley.

configuration errors?

Hello everyone,
I'm trying to build the Haskell Platform 2013.2.0.0 (with required GHC
7.6.3) on Debian GNU/Linux 6 (AKA Debian Squeeze).
So far, I've stumbled upon some a few errors, but I've managed to solve
them and I have let the maintainers know. Now I'm stuck with an error
while configuring the "network" package (see the end of this email). As
such error has no accompanying diagnostics, I don't know how I could fix
it. Any suggestions? Thanks for your attention.
Have a nice day.

I think that the next logical step would be to configure the network
package by hand and see what error comes up. `cabal unpack network'
followed by `cabal configure' in the relevant directory should
hopefully provide a more meaningful error.

Thanks for your suggestion. Indeed, I considered using "cabal", but
since its Hackage page lists many dependencies, I gave up installing it
by hand (something I did for the "alex" package to fix a build issue).
Moreover, according to Hackage "cabal" depends on "network":
http://hackage.haskell.org/package/cabal-install
Therefore we would have a chicken-and-egg problem here, wouldn't we?
Unless "cabal" could be built and installed for off-line use only.
