Support for Kitty's Graphics Protocol

[luiscborbon]

Although Sixel protocol is already supported, I consider a great feature to add support for the Kitty's Graphics Protocol.

When working with Jupyter notebooks in the Terminal using the matplotlib module (under Euporie or ptpython), the following error message is being displayed:

Error: This terminal does not support the graphics protocol use a terminal such as kitty, WezTerm or Kons ole that does. If you are running inside a terminal multiplexer such as tmux or screen that might be inte rfering as well.

Discussions on the differences between these two protocols can be found here:

@luiscborbon - what are you using for your underlying terminal? I assume you are using one that does implement kitty's graphics protocol.

@cboecking recently migrated to the the Kitty terminal, because Alacritty still does not support this protocol.

@luiscborbon - confirmed thanks. I will shorting be in the same situation, and I was curious to understand your setup.

[cboecking]

@luiscborbon - do you mind pointing me to the resources you used to interact with and execute Jupyter from the cli?

mainly:

• aerospace
• home-manager (nixpkgs)
• terminal emulator (eg. kitty, alacritty, ghostty)
• zellij
• uv (python package manager)
• helix editor
• justfile
• jupytext
• euporie or ptpython

justfile

#!/usr/bin/env just --working-directory ./ --justfile
alias sy := sync
alias rn := run
# alias t := test
alias rp := repl

# list available tasks
default:
  @just --list

# convert notebook to scriptbook
convert:
  uv run jupytext --to pypercent code/*.ipynb

# sync dependencies

# repl

  uv run ptpython

  uv run euporia-console

There is already ongoing feature request: #2814 which I believe every zellij user would love to see done
