asciinema2gif
Generate animated GIFs from asciinema terminal recordings.
Motivation
The asciinema tool is a wonderful way to record and share terminal sessions.
Unfortunately, it's not currently possible to embed the output in places like
README files on GitHub repos. This tool provides a solution for that.
Usage
asciinema2gif [options] <asciinema_id|asciinema_api_url>
options:
-s <size>, --size <size> One of 'small', 'medium', 'big'
-p <speed>, --speed <speed> Any integer (whole number) to multiply regular speed by
-t <theme>, --theme <theme> One of 'asciinema', 'tango', 'solarized-dark', 'solarized-light', 'monokai'
-o <file>, --output <file> File to write to (defaults to 'asciicast.gif' in current directory)
-h, --help Show this help.Examples:
$ asciinema2gif --size small --speed 2 --theme solarized-dark 8332An asciicast.gif file will then be generated for you to embed and share.
$ asciinema2gif --theme solarized-light -o "${HOME}/Desktop/another.gif" https://asciinema.org/api/asciicasts/8332In this case an another.gif file will be generated on your Desktop. Using the full URL is useful if you want to get an asciicast not from the official website.
URL Format
asciinema2gif works by visiting the given webpage, starting the asciicast, screenshotting it repeatedly, and finally stitching it together. The /api/asciicasts/ format of an asciinema website (e.g. https://asciinema.org/api/asciicasts/8332), as opposed to the main /a/ format (e.g. https://asciinema.org/a/8332), makes this operation easier (see usage), hence why it is a requirement.
