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. -- Don
