A JupyterLab extension. Integrate JupyterLab and Neovim
Project description
Neopyter
The bridge between Neovim and Jupyter Lab, edit in Neovim and preview/run in Jupyter Lab.
How does it work?
This project includes two parts: a JupyterLab extension
and a Neovim plugin
- The
JupyterLab extension
exposes functions ofJupyter lab
, and provides a remote procedure call(RPC) service - The
Neovim plugin
calls the RPC service when it receives events fromNeovim
viaautocmd
This project provides two work modes for different network environments. If the browser where your jupyter lab is
located cannot directly access nvim, you must use proxy
mode; If you need to collaborate and use the same Jupyter with
others, you must use direct mode

-
direct
mode: (default, recommended) In this mode, neovim is server and neovim plugin(neopyter) is listening toremote_address
, the browser where jupyter lab is located will connect to neovim -
proxy
mode: In this mode, Jupyter lab server(server side, the host you runjupyter lab
to start JupyterLab) is server and jupyter lab server extension(neopyter) is listening to${IP}:{Port}
, the neovim plugin(neopyter) will connect to${IP}:{Port}
Ultimately, Neopyter
can control Juppyter lab
. Neopyter
can implement abilities like jupynium.nvim.

Installation
JupyterLab Extension
To install the jupyterlab extension, execute:
pip install neopyter
Configure JupyterLab
in side panel
mode
: Refer to the previous introduction about modeIP
: Ifmode=proxy
, set to the IP of the host where jupyter server is located. Ifproxy=direct
, set to the IP of the host where neovim is locatedPort
: Idle port of theIP
's' host
NOTICE: all settings is saved to localStorage
Neovim plugin
With 💤lazy.nvim:
{
"SUSTech-data/neopyter",
---@type neopyter.Option
opts = {
mode="direct",
remote_address = "127.0.0.1:9001",
file_pattern = { "*.ju.*" },
on_attach = function(bufnr)
-- do some buffer keymap
end,
highlight = {
enable = true,
shortsighted = false,
},
parser = {
-- trim leading/tailing whitespace of cell
trim_whitespace = false,
}
},
}
Suggest keymaps(neopyter
don't provide default keymap):
on_attach = function(buf)
local function map(mode, lhs, rhs, desc)
vim.keymap.set(mode, lhs, rhs, { desc = desc, buffer = buf })
end
-- same, recommend the former
map("n", "<C-Enter>", "<cmd>Neopyter execute notebook:run-cell<cr>", "run selected")
-- map("n", "<C-Enter>", "<cmd>Neopyter run current<cr>", "run selected")
-- same, recommend the former
map("n", "<space>X", "<cmd>Neopyter execute notebook:run-all-above<cr>", "run all above cell")
-- map("n", "<space>X", "<cmd>Neopyter run allAbove<cr>", "run all above cell")
-- same, recommend the former, but the latter is silent
map("n", "<space>nt", "<cmd>Neopyter execute kernelmenu:restart<cr>", "restart kernel")
-- map("n", "<space>nt", "<cmd>Neopyter kernel restart<cr>", "restart kernel")
map("n", "<S-Enter>", "<cmd>Neopyter execute runmenu:run<cr>", "run selected and select next")
map("n", "<M-Enter>", "<cmd>Neopyter execute run-cell-and-insert-below<cr>", "run selected and insert below")
map("n", "<F5>", "<cmd>Neopyter execute notebook:restart-run-all<cr>", "restart kernel and run all")
end
Quick Start
- Open JupyterLab
jupyter lab
, there is a sidebar namedNeopyter
, which display neopyter ip+port - Open a
*.ju.py
file in neovim - Now you can type
# %%
in Neovim to create a code cell.- You'll see everything you type below that will be synchronised in the browser
Available Vim Commands
- Status
:Neopyter status
alias to:checkhealth neopyter
currently
- Server
:Neopyter connect [remote 'ip:port']
, e.g.:Neopyter command 127.0.0.1:9001
, connectJupyter lab
manually:Neopyter disconnect
- Sync
:Neopyter sync current
, make sync current*.ju.*
file with the currently open*.ipynb
:Neopyter sync [filename]
, e.g.:Neopyter sync main.ipynb
- Run
:Neopyter run current
, same asRun
>Run Selected Cell and Do not Advance
menu inJupyter lab
:Neopyter run allAbove
, same asRun
>Run All Above Selected Cell
menu inJupyter lab
:Neopyter run allBelow
, same asRun
>Run Selected Cell and All Below
menu inJupyter lab
:Neopyter run all
, same asRun
>Run All Cells
menu inJupyter lab
- Kernel
:Neopyter kernel restart
, same asKernel
>Restart Kernel
menu inJupyter lab
:Neopyter kernel restartRunAll
, same asKernel
>Restart Kernel and Run All Cells
menu inJupyter lab
- Jupyter
:Neopyter execute [command_id] [args]
, executeJupyter lab
's command directly, e.g.:Neopyter execute notebook:export-to-format {"format":"html"}
Integration
neoconf.nvim
If neoconf.nvim is available, neopyter
will automatically register/read neoconf
settings
{
"neopyter": {
"mode": "proxy",
"remote_address": "127.0.0.1:9001"
}
}
