asciinema usage with svg-term-cli to create SVG movies

GNU/Linux ◆ xterm ◆ bash 2668 views

asciinema, when used with svg-term-cli, allows you to create SVG animations instead! These movies are vector animations, perfectly suited for interactions in the shell. They are smaller than video files, and can be zoomed without loss of quality. Additionally, no JavaScript will be required.

(disadvantage: having lots of them on your site will make the browser slow - so I recommend to stick to the JavaScript version. For one, however, it should be fine - useful when JS is not allowed)

<body>
  <div id="player"></div>
  <script src="asciinema-player.min.js"></script>
  <script>
    AsciinemaPlayer.create(
      '/assets/377532.cast',
      document.getElementById('player'),
      { cols: 71, rows: 18 }
    );

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

While this site doesn't offer 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 run the following command to create GIF file:

agg https://asciinema.org/a/377532 377532.gif

Or, if you already downloaded the recording file:

agg 377532.cast 377532.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.
