Converting asciinema output to gif

Question

Can I convert a .json file; generated by a program like asciinema; into an animated .gif?

Solution

Yes. While asciinema doesn't provide this natively, there are tools out there that can facilitate that for you.

You can create your local recording like so:

asciinema rec my_recording.json

And then feed that into a tool like asciicast2gif:

./asciicast2gif my_recording.json my_recording.gif

$ asciinema rec my_recording.json asciinema: Too many arguments. See 'asciinema --help'.

@user84207: I'm not sure what's going on; I just tested this on the latest version of asciinema (1.4.0) and it still seems to be working for me. If you run asciinema without any parameters (or asciinema --help), you should see almost the exact same command listed.

It was an older version

From a comment in the source code: # run phantomjs to take screenshots while asciinema-player runs. That's a pretty poor solution, oops! I would use a recording utility other than asciinema, like ttystudio.
