demos: add automated demo of cloning Git repo The automation is mostly copied from https://github.com/arxanas/git-branchless/tree/master/demos, so big thanks to @arxanas for writing that! 2021-10-22 19:24:02 +03:00			`#!/bin/bash`

demos: replace asciinema by screenshots The demos don't need to be animated - the user wouldn't miss anything if they skipped to the end. So let's just show the full output so the user can read through it at their own pace. We could use plain text, but I think the colors are helpful, so I went with screenshots. Closes #166. 2022-10-21 08:13:09 +03:00			`run_command() {`

demos: add a --fast mode to speed up recording It can take quite a while to record a demo. This patch adds a `--fast` flag for reducing delays to a tenth of the usual. You can play the recording with `asciinema play -s 0.1` to get close-to-normal speed (except that command delays will be slower). That way you can adjust timings with shorter round-trips. 2021-10-23 19:34:58 +03:00			`}`
demos: replace printf by regular shell variable expansion This makes it clearer where each variable goes since they're not all called "%s". I'm about to add more variables. 2021-10-23 19:22:45 +03:00
