Just a quick description of a patch I just pushed to the xmonad-contrib darcs repo. First, I cleaned up DynamicLog and added a bunch of documentation and examples -- getting a working status bar seems like one of the more difficult aspects of a typical xmonad setup, so hopefully this will go some ways towards fixing that.
In another step to make setting up a useful status bar easier, I also added a new field to the PP record, ppExtras. This is a list of 'loggers', i.e. (X (Maybe String)) actions, which will be run each time the status is generated, and their output added to the normal window title + layout + workspace information. As an example of the sorts of things you can put there, and as a repository for useful loggers that people might create, I also added a new module, XMonad.Util.Loggers. The upshot of all this is that I used to have a separate script to get the time and date, battery information, and load averages, into which I would pipe the output of xmonad, and then pipe the output of that script into dzen. Now, I no longer have a separate script, I can just throw a few loggers in the ppExtras field of my PP format, and hey presto! Simpler, easier to maintain, and easier for newcomers to figure out.
If you find the new ppExtras feature useful, I hope you'll create some new Loggers and put them in the Loggers module. And feel free to improve upon/generalize the ones that are already there. Ideally there should be a wide array of useful, configurable loggers that new users can choose from when constructing their preferred status bar.
happy xmonading,
And so your plan of world domination has been eventually revealed! You want to get rid of the very reasons why xmobar had to be written! I'll fight it to death!! ;)
I'm just kidding... very nice idea, indeed.
Just one question: why Maybe String? I had a very quick read at your code, but as far as I understand using 'catMaybes' means that 'Just []' and 'Nothing' have the very same meaning. Am I wrong?
Cheers, Andrea
Of course xmobar is still a better solution in most cases -- the ppExtras are only printed each time there is a windowset change, which would mean that the displayed data may become very stale! I'm not sure that we should recommend ppExtras for clocks and such for this reason. Cheers, Spencer Janssen
