Verifying the artifacts

First, download the checksums.txt file, for example, with wget:

wget 'https://github.com/charmbracelet/vhs/releases/download/v0.7.2/checksums.txt'

Then, verify it using cosign:

cosign verify-blob \
  --certificate-identity 'https://github.com/charmbracelet/meta/.github/workflows/goreleaser.yml@refs/heads/main' \
  --certificate-oidc-issuer 'https://token.actions.githubusercontent.com' \
  --cert 'https://github.com/charmbracelet/vhs/releases/download/v0.7.2/checksums.txt.pem' \
  --signature 'https://github.com/charmbracelet/vhs/releases/download/v0.7.2/checksums.txt.sig' \
  ./checksums.txt

If the output is Verified OK, you can safely use it to verify the checksums of other artifacts you downloaded from the release using sha256sum:

sha256sum --ignore-missing -c checksums.txt

Done! You artifacts are now verified!

v0.7.1

Freeze Frame ❄️ 📸

With VHS v0.7.0, you can capture the any moment during tape execution. Just add in Screenshot <filename>.png to your tapes:

Type ls
Enter

# Capture the output of 'ls'
Screenshot files.png

# Now, continue as you normally would
Type 'cd ..'
Enter

Your tape outputs a GIF, and outputs a file named files.png.

Copy-Paste Functionality!

VHS can now talk to your system clipboard. Please keep this in mind when executing tapes from unknown sources.

Warning

You should never curl pipe into VHS, it's similar to executing a bash script on your computer!

Copy "https://github.com/charmbracelet/huh"

Type 'curl '

Paste

Enter

New Modifiers + Keys Alert!

VHS v0.7.0 has some new additions: introducing the top level Shift+ modifier and the Insert + Delete keys!

# Shift things up a bit!
Shift+A
Shift+Tab
Shift+Enter

To avoid cursor blinking, simply use the CursorBlink setting (defaults to true).

v0.5.0

VHS Sorcery 🪄

This release of VHS includes a brand new Source command:
You can now include (Source) other tape files into other tape files to reuse collections of commands that you find yourself repeating. This allows you to build tape modules and compose parent tape files.

To get started, let's create two tape files:

touch source.tape
touch demo.tape

In source.tape place any commands you repeat often

Type "I'm being summoned."
Sleep 500ms
Enter

Then, in demo.tape, you can Source source.tape which will execute all the commands found in the sourced tape file.

Output out.gif
Set Height 1000
Source source.tape # this will execute all commands in ./source.tape
Type "That's all folks"
Enter

When you run vhs demo.tape it will perform all the commands within the tape file and when it reaches the Source invocation it will execute all the commands in type.tape:

Other features

• feat: Alt+Enter by @maaslalani in #305

v0.4.0

Terminal Decorations 🎨

The latest version of VHS includes a ton of new settings for you to play around with! These settings allow you to decorate your GIFs and make them look even more like terminal emulators.

This release also includes a new Alt command, a --quiet flag for silent outputs, and bug fixes when starting up different shells.

New Settings

• Margin: Adds a margin around the outside of your terminal, while Padding allows you to add padding inside the terminal.
• MarginFill: Adds a background color to the outside of the terminal. To change the background color of the terminal itself, use Set Theme and specify the background.
• WindowBar: Adds a terminal window frame/bar to the top of the GIF. This value can be one of Colorful, ColorfulRight, Rings, or RingsRight.
• WindowBarSize: Sets how the WindowBar should appear.
• BorderRadius: Sets the border radius of the terminal.

Set Margin 80
Set MarginFill "#674EFF"
Set WindowBar "Colorful"
Set WindowBarSize 40
Set BorderRadius 8

Launch with Shell

This version of VHS performs the Shell change upon launch, rather than switching shells after starting the ttyd process. This change should result in slightly faster recordings and reduce the occurrence of buggy flashes at the start of GIFs that appeared occasionally when shell switching was slow.

Set Shell zsh

Alt command

VHS now supports pressing the Left Alt key with the newly introduced Alt command. It behaves similarly to pressing Ctrl along with another key.

Alt+V

Quiet Output

If you prefer to create your VHS GIFs without any output, simply add the -quiet flag. This will minimize any output to just the essentials.

vhs demo.tape --quiet

v0.3.0

Hosted & Shareable GIFs

Now you can automatically publish your GIFs to vhs.charm.sh and get a unique URL for your GIFs to share with your friends, coworkers, and the internet.

More details on the new ✨ Mystical Charm™ Blog ✨

To get started use:

vhs cassette.tape --publish

After the generation, you will get a unique URL for your GIF hosted on Charm™ servers.

• https://vhs.charm.sh/6CIuXvkNEMi7wJSOVWXORY.gif

If you would like to, before publishing, see the GIF locally or simply forgot to use the --publish flag, you can use the publish command which allows you to simply publish GIFs. The following will give you a unique URL similar to the above, without needing to generate the GIF from the tape again.

vhs publish output.gif

Output Flag

If you need a quick way to produce an output to a location without editing a tape file, simply use the --output flag to set the location of the output on the fly. This is useful when you need to change the output name or file type and don't want to edit the tape file.

vhs demo.tape --output new-location.gif --output new-format.mp4

Additional Changes

• ttyd listens on loopback interface only (thanks @rcw5)

v0.2.0

Lights, Camera, Action!

Write tape files by simply using the terminal! ✨

VHS Record

VHS v0.2.0 comes with brand new recording functionality. 📹

To get started, run:

vhs record > record.tape

Perform any actions you want to see in your demo. And, then exit the terminal session to finish.

After the session is recorded, you can make edits to the .tape file that was just recorded and then use VHS to generate the GIF file.

vhs < record.tape

Brand New Themes

Now, Set Theme may also take a named theme to use as the color scheme. To use this feature, pass a string from vhs themes to the Set Theme command.

Set Theme dracula

Change Shells

VHS now allows you to use a shell other than bash for your demos. You can use the Set Shell command in the tape file to change shells.

Set Shell zsh 

Fixes

• Exit VHS process gracefully in event of error or cancellation
• Fix leakless windows browser for go-rod
• Use powershell / cmd prompt on windows
