vhs - small utility to record a demo from the terminal

I discovered this while I was working on a new gem: agents_homedir when I discovered this: https://github.com/charmbracelet/vhs

How come I did not know about it? This is amazing for CLI recordings as GIFs.

Here is what I simply did for my gem:

Output agents_homedir-demo.gif

Require bundle

Set Shell "zsh"
Set Width 2800
Set Height 1700
Set FontSize 32
Set Padding 24
Set TypingSpeed 35ms
Set WindowBar "Colorful"

Hide
Type "source /opt/homebrew/opt/chruby/share/chruby/chruby.sh"
Enter
Type "chruby ruby-4.0.1"
Enter
Show

Ctrl+L
Sleep 1s

Type "irb --simple-prompt --noautocomplete"
Enter
Wait+Line />>/
Sleep 1s

Type "require 'agents_homedir'"
Enter
Wait+Line />>/
Sleep 2s

Type "AgentsHomedir.installed.map(&:name)"
Enter
Wait+Line />>/
Sleep 2s

Type "AgentsHomedir.installed?(:codex)"
Enter
Wait+Line />>/
Sleep 2s

Type "AgentsHomedir.home(:codex)"
Enter
Wait+Line />>/
Sleep 2s

Type "AgentsHomedir.installed?(:claude_code)"
Enter
Wait+Line />>/
Sleep 2s

Type "AgentsHomedir.home(:claude_code)"
Enter
Wait+Line />>/
Sleep 2s

And it created this amazing GIF

. I love this kind of focused utility.
