|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 email@example.com) and
XMonad.Util.RunInXTerm (by Andrea Rossato).
For an example usage of runInTerm see XMonad.Prompt.Ssh
For an example usage of runProcessWithInput see
For an example usage of runProcessWithInputAndWait see
|Return output if the command succeeded, otherwise return ().
This corresponds to dmenu's notion of exit code 1 for a cancelled invocation.
|Wait is in µs (microseconds)
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.
, ((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.
|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
|Run a given program in the preferred terminal emulator; see runInTerm. This makes use of safeSpawn.
Multiplies by ONE MILLION, for functions that take microseconds.
|Launch an external application through the system shell and return a Handle to its standard input.
