Terminal recordings

Record and embed copyable terminal sessions with asciinema.

asciinema records terminal text and timing data rather than video. Recordings stay sharp, remain copyable, and are usually much smaller than screen video.

Install the recorder, run asciinema rec theme-tour.cast, and put the resulting file in a page bundle or under static/casts/.

{{< asciinema src="/casts/theme-tour.cast" rows="8" cols="80"
     idleTimeLimit="1.5" >}}

cols, rows, speed, idleTimeLimit, autoplay, loop, controls, fit and theme are supported. theme="auto" follows the site’s light/dark mode; pass an asciinema palette name to keep a recording on a fixed palette.

Data-driven layouts can use the same player without copying shortcode markup:

go-html-template

{{ partial "asciinema.html" (dict
  "page" . "src" .Params.cast "id" "release-demo"
  "controls" "auto" "fit" "width" "theme" "auto") }}

Autoplay is off by default. The player version is pinned in data/cdn.yaml; see Dependencies for CDN and self-hosting options.
