xmonad-contrib-bluetilebranch- Third party extensions for xmonad

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 :: MonadIO m => FilePath -> [String] -> String -> m StringSource

Returns the output.

runProcessWithInputAndWait :: MonadIO m => FilePath -> [String] -> String -> Int -> m ()Source

Wait is in s (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:

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

safeSpawnProg :: MonadIO m => FilePath -> m ()Source

Like safeSpawn, but only takes a program (and no arguments for it). eg.

 safeSpawnProg "firefox"

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 functions that take microseconds.

Use like:

 (5.5 `seconds`)

spawnPipe :: MonadIO m => String -> m HandleSource

Launch an external application through the system shell and return a Handle to its standard input.

hPutStr :: Handle -> String -> IO ()

Computation hPutStr hdl s writes the string s to the file or channel managed by hdl.

This operation may fail with:

hPutStrLn :: Handle -> String -> IO ()

The same as hPutStr, but adds a newline character.
