New Layout: ThreeColumnsMiddle

Hi, I modified the layout "ThreeColumns" such that the master window is centered. In my opinion this layout is especially useful when using a huge screen (30" with 2560x1600 in my case). Like in the original layout, there can be more than one master window. Furthermore, the size of the middle section can be changed. Code and screenshot: http://server.c-otto.de/xmonad/ Sorry for not providing a patch, but I have no experience with darcs. Bye, -- Carsten Otto carsten@c-otto.de www.c-otto.de

Hi Carsten, looks nice! Please do consider submitting this as a darcs patch. There is actually a tutorial to walk you step-by-step through exactly that process: http://haskell.org/haskellwiki/Xmonad/xmonad_development_tutorial Hopefully the tutorial should make it easy -- if there's anything that's confusing or unclear, consider it a bug in the tutorial and please let us know! -Brent

There is. It seems XSelection.hs makes use of C preprocessing, which cannot be handled when generating haddock documentation.

It works OK for me; I think you may just need a more recent version of haddock. Which version of haddock do you have installed (just type 'haddock --version')? I will add a note about this on the tutorial page. -Brent

Yup, that is too old. The most recent version is, I think, 2.4.1. You can get it from hackage.haskell.org; if you have cabal-install you can even just say 'cabal update && cabal upgrade haddock'. -Brent
