spawn package:xmonad-contrib is:module
Provides a way to modify a window spawned by a command(e.g shift it to
the workspace it was launched on) by using the _NET_WM_PID property
that most windows set on creation. Hence this module won't work on
applications that don't set this property.
A module for spawning a pipe whose
Handle lives in the Xmonad
state.
A module for spawning a command once, and only once. Useful to start
status bars and make session settings inside startupHook. See also
SessionStart for a different and more flexible way to run
commands only on first startup.
