===== VHS in picture =====

[[https://github.com/charmbracelet/vhs|VHS]] is virtually identical to [[https://asciinema.org/|asciinema]]. Nevertheless **VHS** uses a declarative approach (by creating a ''%%.tape%% files''). It can be used to automate the execution of a scenario consisting of a series of commands to be executed, and then to record the results of the actions in the form of videos in different formats (webm, mp4, gif), which can be particularly useful for documentation or knowledge sharing.

Starting with this file ''%%demo-vhs.tape%%''

<code bash>
Output demo-vhs.gif

Require nix

Set TypingSpeed 75ms
Set FontSize 18
Set Width 800
Set Height 680

Type "nix-shell -p dotacat neofetch"

Type "neofetch" Sleep 500ms Enter Sleep 2s

Type "dotacat --help | dotacat" Sleep 500ms Enter 

Sleep 5s
</code>

We obtain the result below with the following command ''%%vhs demo-vhs.tape%%''
