I’m currently working on an ASCIIcast, containing a small tutorial introducing ImageMagick v7.0.x

This is still work-in-progress. I make no promises when it will be ready. If you want to get some ideas about the power of ImageMagick (or if you want to learn things about it which you didn’t know so far), go to my collected StackOverflow answers from the past few years and have a look at these:

Don’t forget: upvote these answers which you thing deserve it. Leave a comment, if you have further questions.

If you haven’t seen my other ASCIInema recordings so far, feel free to watch them as well:

You can replay the downloaded recording in your terminal using the asciinema play command:

If you don't have asciinema CLI installed then see installation instructions.

Use with stand-alone player on your website

Download asciinema player from the releases page (you only need .js and .css file), then use it like this:

<!DOCTYPE html>
<html>
<head>
  <link rel="stylesheet" type="text/css" href="asciinema-player.css" />
</head>
<body>
  <div id="player"></div>
  <script src="asciinema-player.min.js"></script>
  <script>
    AsciinemaPlayer.create(
      '/assets/146223.json',
      document.getElementById('player'),
      { cols: 240, rows: 60 }
    );
  </script>
</body>
</html>

See asciinema player quick-start guide for full usage instructions.

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/146223 demo.gif

Or, if you already downloaded the recording file:

agg demo.cast demo.gif

Check agg --help for all available options. You can change font family and size, select color theme, adjust speed and more.

See agg manual for full usage instructions.
