Start multiple processes as children of a single j4-dmenu-desktop about j4-dmenu-desktop HOT 6 CLOSED

How do you invoke it exactly? By default the select app will be exec'd without creating a new process (the new process replaces the j4dd process).

from j4-dmenu-desktop.

I have this single line mentioning it in my i3 config:

# rg j4 ~/.config/i3/config
76:bindsym $mod+d exec --no-startup-id j4-dmenu-desktop

I then press command+d then type leafpad and press Enter. Then press command+d, type kate and press Enter and so forth. This is what I get in htop:

Ah you see, that's not up to j4dd ;)

You're seeing the shell process started by i3, which in turn is ordered to start j4dd, which replaced itself properly with the command you selected.

You could use the daemon mode but there's really not that much point unless you're having a slowness issue due to e.g. spinning hard drive and little RAM.

Hmm I might want to try out the daemon mode then; it doesn't seem to be documented in its man page, this repo front page, nor the wiki or the issues. How do I enable and use it?

from j4-dmenu-desktop.

It's not a real daemon more like something waiting in the dark

--wait-on=<path>
    Must point to a path where a file can be created.
    In this mode no menu will be shown. Instead the program waits for <path>
    to be written to (use echo > path). Every time this happens a menu will be shown.
    Desktop files are parsed ahead of time.
    Perfoming 'echo -n q > path' will exit the program.

Hmm, so for i3wm, we can use the following config?

# bindsym $mod+d exec --no-startup-id j4-dmenu-desktop
exec --no-startup-id j4-dmenu-desktop --wait-on=/var/$USER/j4dd.socket
bindsym $mod+d exec --no-startup-id echo > /var/$USER/j4dd.socket

--wait-on doesn't seem to bne supported in 2.16-1+b1. From git-blame it seems it was introduced 2 years ago; so sad newer versions never got packaged to Debian (testing).
