Re: [xmonad] Recommended setup for coding

I have decided to move to the darcs version, but now xmonad hangs. I have downloaded xmonad, XMonadContrib and X11 with darcs and installed them with cabal-install without problems. Xmonad recompiles and starts, but only shows fragmented windows and doesn't react properly on keys and mouse. I have to kill the Xsession with Alt-Print-k in order to return to the login-screen. Even with the most simple xmonad.hs. Everything was fine, as long as I kept the debian installation, but having both installations, I wasn't sure, which version I was running. After removing all debian packages related to xmonad, the problem occurred for the first time. What is wrong? Maybe I have removed to much (for example libghc6-xmonad-dev?), but I had assumed, I would get all needed packages from darcs, except ghc of course. I use Ubuntu-9.10 with ghc-6.10.4.

If you aren't planning anything large-scale, you can use any XMonad install and create modules in your ~/.xmonad/lib directory, which is in the search path when XMonad compiles your config. So, for example:

~/.xmonad/lib/XMonad/Layout/ANewLayout.hs ~/.xmonad/lib/XMonad/Util/SomeUtilityStuff.hs

You can import these in your xmonad.hs as if they were part of xmonad-contrib. Using the same hierarchy as the rest of XMonad also makes it easy to integrate your modules into the xmonad-contrib darcs repo if/when you think they're worth it.

There are a number of problems with this simple method though:

* XMonad will recompile _all_ your imported lib/* modules on each recompile, so you can't keep too much stuff in there. It will also compile them without optimizations to reduce the recompilation time, and Haskell without optimization isn't really that fast anymore.

* You can't modify current modules in this way (unless you want to "overlay" them with a completely new one).

* You still need to cabal-install the darcs version when you want to publish patches, since you need to test them at least once against the current head.

So if you find yourself writing a lot of modules, or sending patches to xmonad-contrib regularly, you'll need to work with cabal-install and the xmonad-contrib darcs repo. It's still fairly simple:

* Perform your modifications in the darcs directory. * Type "cabal install" at its top-level when you're done with a change. * "xmonad --recompile" to recompile your xmonad.hs using the new lib. * And you're working in a darcs repo, so you have version control handy.

As for the Haskell Platform, it contains cabal-install so if you can't find a cabal-install package for Ubuntu you can install that instead., but there's nothing else you need in it.

Hope it helps

I would like to try some haskell coding with xmonad. What is the best xmonad install for this purpose?

Is it essential to use the cabal version? What is your opinion about the "Haskell Platform" instead of ghc --> http://sporkcode.wordpress.com/2009/07/11/installing-the-haskell-platform-in...

So far i am using ghc/xmonad-0.9.1 from debian sid, installed on ubuntu 9.10. If possible i would like to keep this unchanged, because everything works fine.
