xmonad-contrib-0.7: Third party extensions for xmonadSource codeContentsIndex
MaintainerChristian Thiemann <mail@christian-thiemann.de>
This modules provides several commands to run an external process. It is composed of functions formerly defined in XMonad.Util.Dmenu (by Spencer Janssen), XMonad.Util.Dzen (by glasser@mit.edu) and XMonad.Util.RunInXTerm (by Andrea Rossato).
runProcessWithInput :: FilePath -> [String] -> String -> IO String
runProcessWithInputAndWait :: FilePath -> [String] -> String -> Int -> IO ()
safeSpawn :: MonadIO m => FilePath -> String -> m ()
unsafeSpawn :: MonadIO m => String -> m ()
runInTerm :: String -> String -> X ()
safeRunInTerm :: String -> String -> X ()
seconds :: Rational -> Int
spawnPipe :: String -> IO Handle

For an example usage of runInTerm see XMonad.Prompt.Ssh

For an example usage of runProcessWithInput see XMonad.Prompt.DirectoryPrompt, XMonad.Util.Dmenu, XMonad.Prompt.ShellPrompt, XMonad.Actions.WmiiActions, XMonad.Prompt.WorkspaceDir

For an example usage of runProcessWithInputAndWait see XMonad.Util.Dzen

runProcessWithInput :: FilePath -> [String] -> String -> IO StringSource
Return output if the command succeeded, otherwise return (). This corresponds to dmenu's notion of exit code 1 for a cancelled invocation.
runProcessWithInputAndWait :: FilePath -> [String] -> String -> Int -> IO ()Source
Wait is in µs (microseconds)
safeSpawn :: MonadIO m => FilePath -> String -> m ()Source

safeSpawn bypasses XMonad.Core's spawn command, because spawn passes strings to /bin/sh to be interpreted as shell commands. This is often what one wants, but in many cases the passed string will contain shell metacharacters which one does not want interpreted as such (URLs particularly often have shell metacharacters like '&' in them). In this case, it is more useful to specify a file or program to be run and a string to give it as an argument so as to bypass the shell and be certain the program will receive the string as you typed it. unsafeSpawn is internally an alias for XMonad's spawn, to remind one that use of it can be, well, unsafe. Examples:

 , ((modMask, xK_Print), unsafeSpawn "import -window root $HOME/xwd-$(date +%s)$$.png")
 , ((modMask, xK_d    ), safeSpawn "firefox" "")

Note that the unsafeSpawn example must be unsafe and not safe because it makes use of shell interpretation by relying on $HOME and interpolation, whereas the safeSpawn example can be safe because Firefox doesn't need any arguments if it is just being started.

unsafeSpawn :: MonadIO m => String -> m ()Source
runInTerm :: String -> String -> X ()Source
Open a terminal emulator. The terminal emulator is specified in defaultConfig as xterm by default. It is then asked to pass the shell a command with certain options. This is unsafe in the sense of unsafeSpawn
safeRunInTerm :: String -> String -> X ()Source
Run a given program in the preferred terminal emulator; see runInTerm. This makes use of safeSpawn.
seconds :: Rational -> IntSource

Multiplies by ONE MILLION, for use with runProcessWithInputAndWait.

Use like:

 (5.5 `seconds`)
spawnPipe :: String -> IO HandleSource
Launch an external application through the system shell and return a Handle to its standard input.
