Recording terminal sessions with asciinema
I was looking for a way to improve the README page of some of my projects by showing a recording of a terminal session to explain how to use them.
There's a few packages for that like simplescreenrecorder to produce a MPEG-4 or WebM video. And of course a GIF would the easiest to embed but it's much too heavy for that.
That's when I found asciinema, a cool free and open source solution to simplify the process.
You launch it with
asciinema rec in a terminal, then do your thing, finish by
exit, and that's it your recording will be uploaded to the website.
with an image like the following examples.
I recorded an asciicast showing how to get the weather with forecaster:
Another one for my chess engine littlewing:
And a last one for closh:
Thanks to asciinema my README pages are much prettier now.
