[xmonad] Re: Use regexps for className matching?

I couldn't find any examples of this in the config | archive.. 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"
