[xmonad] Re: Use regexps for className matching?

You can use one of the haskell regex libraries and define an operator for the managehook like so:

...

import Text.Regex.Posix ((=~))

q ~? x = fmap (=~ x) q

and then your example is simply

...

className ~? "Google .*" --> doShift "1"

Having someone interested write an extension module of regex combinators for this kind of thing would be useful.

Other than lifting (=~) and possibly another function or two, what would this do? I'd be happy to put the two lines it takes to define (~?) into a module, but that seems a bit slim (I guess it couldn't hurt though). -- Gravity brings me down.
