CLI Demo GIF Generator

Generate terminal demo GIFs using vhs. When asked to create a CLI demo GIF, produce a .tape file and render it.

Steps

1. Create tape file

Place tape files in docs/demo/ to keep the project root clean:

mkdir -p docs/demo

Write the tape file with appropriate settings for the project's CLI:

Output docs/demo/demo.gif

Set Shell "bash"
Set FontSize 16
Set Width 900
Set Height 500
Set Padding 20
Set Theme "Catppuccin Mocha"
Set TypingSpeed 50ms

Type "command --help"
Enter
Sleep 2s

2. For unpublished CLI packages

Use Hide/Show to configure aliases before the visible demo starts:

Hide
Type "alias mycli='bun run src/cli/index.ts'"
Enter
Sleep 500ms
Show

Type "mycli --help"
Enter
Sleep 2s

3. Render the GIF

vhs docs/demo/cli.tape
