description = ''
Configuration from which XMonad gets compiled. If no value is
specified, a vanilla xmonad binary is put in PATH, which will
attempt to recompile and exec your xmonad config from $HOME/.xmonad.
This setup is then analogous to other (non-NixOS) linux distributions.
If you do set this option, you likely want to use "launch" as your
entry point for xmonad (as in the example), to avoid xmonad's
recompilation logic on startup. Doing so will render the default
"mod+q" restart key binding dysfunctional though, because that attempts
to call your binary with the "--restart" command line option, unless
you implement that yourself. You way mant to bind "mod+q" to
<literal>(restart "xmonad" True)</literal> instead, which will just restart
xmonad from PATH. This allows e.g. switching to the new xmonad binary
after rebuilding your system with nixos-rebuild.
If you actually want to run xmonad with a config specified here, but
also be able to recompile and restart it from a copy of that source in
$HOME/.xmonad on the fly, you will have to implement that yourself
using something like "compileRestart" from the example.
This should allow you to switch at will between the local xmonad and
the one NixOS puts in your PATH.
