Hi! I've just released xmobar-0.6 "The Existentialist", my status bar for XMonad. Grab the source here: http://hackage.haskell.org/cgi-bin/hackage-scripts/package/xmobar-0.6 Screen shot: http://gorgias.mine.nu/xmobar/xmobar-0.6.png If you cannot wait for ghc to do his job, here you can find a binary with 2 sample configuration files: http://gorgias.mine.nu/xmobar/ About this release: 1. Plugin support. I've already sent a mail regarding the way through which I decided to add plugin support,[1] so I'm not giving details here. There is an example within the distribution: Plugins/HelloWorld.hs See below (or the README) for instruction on how to install it. The precompiled binary linked above was compiled with it. In the README there are instructions on how to write plugins (should be very easy, I hope at least); 2. new way of configuring commands (resulting from the above change): I hope that makes it easier to configure XMobar: no more tuples but a single command prefixed by "Run". See the configuration samples and instruction in the README; 3. colors are off by default now, and you need to configure them explicitly. See the config sample or the README to find out how. 4. Performance: I did quite some profiling. The most resource consuming part was the network monitor. So I rewrote it. Now XMobar should be quite optimized. Test and report back please. There's room for more optimization I think, but the results so far seem good to me. Hope you'll enjoy. All the best, Andrea [1] My previous mail about existential plugin-ing: http://www.haskell.org/pipermail/xmonad/2007-July/001413.html To install the HelloWorld plugin: 1. import the plugin module in Config.hs, by adding: import Plugins.HelloWorld 2. add the plugin data type to the list of data types in the type signature of "runnableTypes" in Config.hs. For instance, for the HelloWorld plugin, change "runnableTypes" into: runnableTypes :: (Command,(HelloWorld,())) runnableTypes = undefined 3. Rebuild and reinstall XMobar. Now test it with: xmobar Plugins/helloworld.config As you may see in the example configuration file, the plugin can be used by adding, in the "commands" list: Run HelloWorld and, in the output template, the alias of the plugin: %helloWorld% That's it.
