Calling DBus from Emacs

This demo uses DBus from within Emacs. The backend is a ruby server, which is automatically started by DBus whenever it’s requested on the session bus. I call one emacs function that delivers messages on the bus and another one that reads messages from the bus.

If you’re new to Emacs, keep an eye on the minibuffer at the bottom of my screen.

All the source is in the Git repo

While this site doesn't provide GIF conversion at the moment, you can still do it yourself with the help of asciinema GIF generator utility - agg.

Once you have it installed, generate a GIF with the following command:

agg https://asciinema.org/a/1488 demo.gif

Or, if you already downloaded the recording file:

agg demo.cast demo.gif
