About

A Jupyter notebook client for your terminal. It aims to emulate the functionality of the classic Jupyter notebook. Built on the excellent textual framework with image support from textual-image.

Demo

Getting started

The easiest way to get started is with uv. To try without installing

uvx --from netbook jupyter-netbook [my_notebook.ipynb]

To install in the current virtual environment

uv pip install netbook

Or install it as a standalone tool

uv tool install netbook

Run it as follows

jupyter-netbook [my_notebook.ipynb]

Terminal Support

Terminal	Status	Image Support	Shift/Ctrl+Enter Support	Notes
Kitty	✅	✅ TGP	✅ Out of the box	Remap some keybindings
Foot	✅	✅ Sixel	✅ Out of the box	Sixel support is flaky
Contour	✅	✅ Sixel	✅ Out of the box
ITerm2	✅	✅ Sixel, TGP	✅ Out of the box	ITerm2 image protocal would probably be supported in the future
Wezterm	✅	✅ TGP	✅ Requires remapping
Windows Terminal	✅	✅ Sixel	✅ Requires remapping	Things kind of work, sometimes...
Ghosty	✅	✅ TGP	✅ Out of the box
Tmux	✅	✅ Sixel, TGP	✅ Requires configuration	See the FAQ on configuration
Alacritty	🤷	❌	✅ Requires remapping	It is quite unlikely that alacritty will support images
Zellij	❌	❌	✅ Out of the box	In theory zellij support sixels, but I couldn't make it work

Frequently asked questions

Q: Why are icons in the toolbar all jumbled up?

A: You need to have Font Awesome installed. Or you can download nerd fonts that already have the glyphs patched in.

Q: How can I start other kernels?

A: You can use --kernel argument. It accepts kernel names shown by jupyter-kernelspec list.

Q: How to see available keybindings?

A: Press 'h' in command mode (i.e. when focus is not in a text area). The keybindings are mostly compatible with the classic Jupyter notebook.

Q: How to remap the keys in my terminal?

A: Here are snippets for a selection of terminal emulators:

• Kitty. Add the following to ~/.config/kitty/kitty.conf

  # Send ctrl+shift+minus to netbook
  map --when-focus-on title:netbook kitty_mod+minus
  

• Wezterm. Add the following to ~/.config/wezterm/wezterm.lua

  local wezterm = require 'wezterm';
  
  return {
    -- ...
  
    keys = {
      {key="Enter", mods="CTRL", action=wezterm.action{SendString="\x1b[13;5u"}},
      {key="Enter", mods="SHIFT", action=wezterm.action{SendString="\x1b[13;2u"}},
      {key="Enter", mods="ALT", action=wezterm.action{SendString="\x1b[13;3u"}},
    },
  }
  

• Windows Terminal. Add the following to settings.json file

  {
    // ...
  
    "keybindings":
    [
      { "command": { "action": "sendInput", "input": "\u001b[13;5u" }, "keys": "ctrl+enter" },
      { "command": { "action": "sendInput", "input": "\u001b[13;2u" }, "keys": "shift+enter" },
      { "command": { "action": "sendInput", "input": "\u001b[13;3u" }, "keys": "alt+enter" }
    ]
  }
  

Euporie, a related project, also has some examples,

Q: Images are not showing up.

A: Make sure your terminal has support for sixels or terminal graphics protocol. By default netbook autodetects support. If this fails, you can force the protocol using the --graphics option.

Q: How to configure tmux?

A: Here are some options to make the experience with tmux better.

Enable extended keys such as ctrl+enter and shift+enter:

set -g extended-keys always
set -g extended-keys-format csi-u
set -as terminal-features 'xterm*:extkeys'

Enable mouse interaction:

set -g mouse on

Make sure COLORTERM environment variable is properly set. This can be achieved e.g. via:

set -g update-environment -r

If your terminal supports Terminal Graphic Protocol (aka kitty protocol), then you can use --graphic tmux-kitty option in netbook to use the passthrough feature of tmux. As of this writing this works in Kitty, ITerm2 and Ghostty. In order to enable passthrough in tmux, add this to the config:

set -g allow-passthrough on

Development

To get set up just run

uv sync
uv run jupyter-netbook
