xmonad-contrib-0.8: Third party extensions for xmonadSource codeContentsIndex
Defines a few convenient operations for raising (traveling to) windows based on XMonad's Query monad, such as runOrRaise. runOrRaise will run a shell command unless it can find a specified window; you would use this to automatically travel to your Firefox or Emacs session, or start a new one (for example), instead of trying to remember where you left it or whether you still have one running.
raise :: Query Bool -> X ()
raiseNext :: Query Bool -> X ()
runOrRaise :: String -> Query Bool -> X ()
runOrRaiseNext :: String -> Query Bool -> X ()
raiseMaybe :: X () -> Query Bool -> X ()
raiseNextMaybe :: X () -> Query Bool -> X ()
raiseEditor :: X ()

Import the module into your ~/.xmonad/xmonad.hs:

 import XMonad.Actions.WindowGo

and define appropriate key bindings:

 , ((modMask x .|. shiftMask, xK_g), raise (className =? "Firefox"))
 , ((modMask x .|. shiftMask, xK_b), runOrRaise "firefox" (className =? "Firefox"))

(Note that Firefox v3 and up have a class-name of "Firefox" and "Navigator"; lower versions use other classnames such as "Firefox-bin". Either choose the appropriate one, or cover your bases by using instead something like (className =? "Firefox" || className =? "Firefox-bin").)

For detailed instructions on editing your key bindings, see XMonad.Doc.Extending#Editing_key_bindings.

raise :: Query Bool -> X ()Source
See raiseMaybe. If the Window can't be found, quietly give up and do nothing.
raiseNext :: Query Bool -> X ()Source
See raise and raiseNextMaybe. Version that allows cycling through matches.
runOrRaise :: String -> Query Bool -> X ()Source
action is an executable to be run via spawn (of XMonad.Core) if the Window cannot be found. Presumably this executable is the same one that you were looking for.
runOrRaiseNext :: String -> Query Bool -> X ()Source
See runOrRaise and raiseNextMaybe. Version that allows cycling through matches.
raiseMaybe :: X () -> Query Bool -> X ()Source

raiseMaybe queries all Windows based on a boolean provided by the user. Currently, there are three such useful booleans defined in XMonad.ManageHook: title, resource, className. Each one tests based pretty much as you would think. ManageHook also defines several operators, the most useful of which is (=?). So a useful test might be finding a Window whose class is Firefox. Firefox 3 declares the class "Firefox", so you'd want to pass in a boolean like (className =? "Firefox").

If the boolean returns True on one or more windows, then XMonad will quickly make visible the first result. If no Window meets the criteria, then the first argument comes into play.

The first argument is an arbitrary IO function which will be executed if the tests fail. This is what enables runOrRaise to use raiseMaybe: it simply runs the desired program if it isn't found. But you don't have to do that. Maybe you want to do nothing if the search fails (the definition of raise), or maybe you want to write to a log file, or call some prompt function, or something crazy like that. This hook gives you that flexibility. You can do some cute things with this hook. Suppose you want to do the same thing for Mutt which you just did for Firefox - but Mutt runs inside a terminal window? No problem: you search for a terminal window calling itself "mutt", and if there isn't you run a terminal with a command to run Mutt! Here's an example (borrowing runInTerm from XMonad.Utils.Run):

 , ((modm, xK_m), raiseMaybe (runInTerm "-title mutt" "mutt") (title =? "mutt"))
raiseNextMaybe :: X () -> Query Bool -> X ()Source
See raiseMaybe. raiseNextMaybe is an alternative version that allows cycling through the matching windows. If the focused window matches the query the next matching window is raised. If no matches are found the function f is executed.
raiseEditor :: X ()Source
raiseBrowser and raiseEditor grab $BROWSER and $EDITOR respectively and they either take you to the specified program's window, or they try to run it. This is most useful if your variables are simple and look like firefox or emacs.
