Asciicast Output

Author: rsteubeCreated Oct 30, 2022Updated Sep 14, 2026

This is probably out of scope but would be nice to have asciicast output (Output: out.cast). I initally wanted gif for the readme and asciicast for the mdbook documentation but then decided against gif due to it's size. Managed to record it by simply spawning an asciinema recording within tmux. Keeping size in sync with the other outputs could be challenge but there are also gif, svg,.. generators available for asciicast. It might even provide an alternative to the chrome dependency (which pushes my cpu to the limit).

Svg

SVG output with svg-term-cli (nice output but high load for playing it)
