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.

Import the module into your
and define appropriate key bindings:
, ((modm .|. shiftMask, xK_g), raise (className =? "Firefox")) , ((modm .|. 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.
raiseMaybe. If the Window can't be found, quietly give up and do nothing.
action is an executable to be run via
safeSpawnProg (of XMonad.Util.Run) if the Window cannot be found.
Presumably this executable is the same one that you were looking for.
Note that this does not go through the shell. If you wish to run an arbitrary IO action
spawn, which will run its String argument through the shell), then you will want to use
raiseMaybe queries all Windows based on a boolean provided by the
user. Currently, there are 3 such useful booleans defined in
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
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
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
runInTerm from XMonad.Util.Run):
, ((modm, xK_m), raiseMaybe (runInTerm "-title mutt" "mutt") (title =? "mutt"))
If a window matching the second argument is found, the window is focused and the third argument is called; otherwise, the first argument is called.
If the window is found the window is focused and set to master otherwise, action is run.
runOrRaiseMaster "firefox" (className =? "Firefox"))
If the window is found the window is focused and the third argument is called
otherwise, the first argument is called
raiseMaster for an example.
if the window is found the window is focused and set to master otherwise, the first argument is called.
raiseMaster (runInTerm "-title ghci" "zsh -c 'ghci'") (title =? "ghci")
If windows that satisfy the query exist, apply the supplied function to them, otherwise run the action given as second parameter.
The same as ifWindows, but applies a ManageHook to the first match instead and discards the other matches
