Remote set-background-image prints never ending kitty-cmd{"ok":true}

[electricjones]

Describe the bug background_image works like a dream, but when I try to remotely change the image using kitty @ set-background-image /path/to/file.png, the image changes, but the terminal scrolls and endless stream of

$ kitty @ set-background-image /path/to/file.png
"ok": true}^[\^[P@kitty-cmd{"ok": true}^[\^[P@kitty-cmd{"ok": true}

The same is true directly from the kitty terminal.

However, using kitty @ set-background-image none removed the background image and does not stream text.

To Reproduce Steps to reproduce the behavior:

1. Set background_image in kitty config
2. Open new kitty instance and see background image
3. run kitty @ set-background-image /path/to/file.png
4. See endless text stream until window eventually crashes from memory failure (many minutes later)

Expected behavior Image simply changes w/o text stream

That is because whatever context you are running the command in, is not processing the response escape codes from kitty. Add --no-response the kitty @ command to silence the responses.

[electricjones]

Thank you for the quick reply. It appears that --no-response is not a valid option for set-background-image

❯ kitty @ set-background-image --no-response /home/mwilson/system/dotfiles/assets/backgrounds/testing2.png
Unknown option: --no-response

Also for grins:

❯ kitty --no-response @ set-background-image /home/mwilson/system/dotfiles/assets/backgrounds/testing2.png
Unknown option: --no-response

and

❯ kitty @ set-background-image /home/mwilson/system/dotfiles/assets/backgrounds/testing2.png --no-response
Must specify exactly 1 argument(s) for set-background-image

And the context I'm using it from is directly in the kitty instance I'm wanting to change. Not over ssh or anything.

You dont run things directly in kitty, you run things in a shell, which is itself running in kitty. And I cannot replicate your issue with either bash or zsh. And I have added --no-response to @ set-background-image in my latest commit

Thank you for clarifying. My shell is zsh.

I will update my kitty version to grab that latest commit.

[electricjones]

Works like a charm with the latest commit. I appreciate it. Fantastic terminal emulator -- it has changed my daily workflow.
