Érico Nogueira dd3f91fbd3 Clean up exec_command. 
Rename pid_t variables "pid", "child" to "child" and "grandchild", since
we were using "child" in comments to refer to the PID stored in "pid".

Use _exit(2) whenever exiting from a forked child; calling exit(3)
should't be done in such a context.

Add missing new lines to error messages. Arguably using stdio in this
context isn't safe either, but we aren't a threaded program and stderr
is always flushed when this function is called, so it won't ouput
previous buffer contents or deadlock.

Fix one _exit(2) call to return 1 as status code, since it should be
indicating a failure.

Add error message in case waitpid(2) fails.

kanshi

kanshi allows you to define output profiles that are automatically enabled and disabled on hotplug. For instance, this can be used to turn a laptop's internal screen off when docked.

This is a Wayland equivalent for tools like autorandr. kanshi can be used on Wayland compositors supporting the wlr-output-management protocol.

Building

Dependencies:

  • wayland-client
  • scdoc (optional, for man pages)
meson build
ninja -C build

Usage

mkdir -p ~/.config/kanshi && touch ~/.config/kanshi/config
kanshi

Configuration file

Each output profile is delimited by brackets. It contains several output directives (whose syntax is similar to sway-output(5)). A profile will be enabled if all of the listed outputs are connected.

profile {
	output LVDS-1 disable
	output "Some Company ASDF 4242" mode 1600x900 position 0,0
}

profile {
	output LVDS-1 enable scale 2
}
