[xmonad] Regexp WM_NAME ?

[Gwern Branwen]

Lift whatever string-match or regexp function you need to the monad?
For example, it looks like you could match isInfixOf on (/tmp); here's
an existing example

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

    myManageHook = (composeAll . concat $ --shifting actions
        [ [ title     =? x --> doCenterFloatToAll | x <- important ]
    ....
        , [ className =? "Skype" <&&> title ~? "Call with " -?>
doSideFloat' CE ]
