Even better. That way one require statement becomes unnecessary.



PS: Now in i3wm I can bind this to something like S-x to either start
programs or run interactive emacs commands (and focus emacs). Similar
behaviour as I had bound S-x to in EXWM :-)

The emacs code now looks like this:

> (defun aa/show-interactive-commands ()
>   (interactive)
>   (seq-sort-by #'length #'<
>              (cl-loop for symbol being the symbols
>                       when (commandp symbol)
>                       collect (symbol-name symbol))))

and I can call it from a script like:

> #!/bin/bash

> if [ $# -eq 0 ]
> then
>     BUFFERS=`emacsclient -e '(aa/show-interactive-commands)' | sed 's/\" 
> \"/)\\\\n(/g' | sed 's/\"//g'`
>     echo -e $BUFFERS 
> else
>     emacsclient -ne "$1" >/dev/null
>     i3-msg -q '[class="Emacs"] focus'
> fi

Which in turn is bound in i3 to Super-x to call

> bindsym Mod4+x exec "rofi -modi 'M-x:~/bin/emacs-interactive-command.sh,run' 
> -combi-modi M-x,run -show combi"
