| Description |
| 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.

|
| Usage
|
|
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.

| See raiseMaybe. If the Window can't be found, quietly give up and do nothing.

|
| See raise and raiseNextMaybe. Version that allows cycling through matches.
|
|
|
| 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.

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"))

|
| 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.
|
|
|
|
|
| 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.
|
|
|
| if the window is found the window is focused and the third argument is called
otherwise, raisef 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
See 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")
