For the following code:

import numpy as np                                                
import matplotlib.pyplot as plt

plt.hist(x)

I can't seem to nail down exactly when it happens but one reliable way is to hit <leader>, wait for which-key.nvim to show up then hit <ESC>

I see it is something to do with the BufUnload autocommand so I guess it's to do with leaving the buffer

Also doing a LSP search for references leads to this happening many times

Hello, this is not a bug but I cannot use the plugin at all. Installation went smoothly and :checkhealth appears fine but I simply cannot fire the plugin using :MagmaInit, it is like the plugin was not installed. I am probably doing something very stupid

:checkhealth

:version

~/.init.vim is empty

Describe the bug E492: Not an editor command: Magma

To Reproduce Simply type :MagmaInit

First of all, amazing work! I've been hoping for a hydrogen-like plugin for neovim for quite a while now, and this is looking to be a great implementation.

Now to the issue, when running UpdateRemotePlugins the following error is thrown:

Encountered TypeError loading plugin at /home/user/.local/share/nvim/site/pack/packer/start/magma-nvim/rplugin/python3/magma.py: 'type' object is not s

  File "<frozen importlib._bootstrap>", line 702, in _load
  File "<frozen importlib._bootstrap>", line 671, in _load_unlocked
TypeError: 'type' object is not subscriptable

It seems like pynvim isn't recognizing the type annotation syntax from the source file. Removing all indexing from type annotations makes the error go away.

Not sure if this is an error on my end or if it's a common problem.

To make it more user friendly it would be nice to add a option that will install jupyter/ipython/ijulia etc (in MagmaInit, or another command like MagmaInstall). Depending on detected filetype

Describe the bug When attempting to install using vim-plug the following error occurs:

fatal: invalid reference: master

To Reproduce Steps to reproduce the behavior:

Install the plugin per the instructions for vim-plug, i.e.:

Plug 'dccsillag/magma-nvim', { 'do': ':UpdateRemotePlugins' }

Expected behavior Vim-plug confirms the plugin installed properly

Fixes #34

This adds two new commands, MagmaInterrupt which sends a SIGINT to the kernel, and MagmaRestart which completely restarts the kernel.

It may be worth to discuss whether MagmaRestart should also clear all output.

Hi there.

Im trying to understand some of the design choices, as Im having trouble with some of the current behaviour. To be more precise, why are you calling MagmaBuffer.clear_interface on every CursorMoved? I would expect this to only be called when the cursor exited a cell / entered a different cell. This causes an excess of ui redraws, and also make it difficult to properly place images using Kitty.

When my computer is under a moderate load, this plugin appears to be massively slowing down opening time: 1 more second!

Is your feature request related to a problem? Please describe. I'm always frustrated when working with images in Vim, this is an awesome plugin, but I tried on a remote desktop through ssh -X or ssh -Y but the image cannot display

Describe the solution you'd like The plugin can output the display in nvim on a remote desktop

Interesting plugin! I've been using nvim-ipy with the Jupyter QT console for some time, but having everything in one window sounds a lot nicer. Anyway back to my requests:

• Would it be possible to have a persistent output window below the executed cell that doesn't cover the code? Something like in this other plugin that reads .ipynb files.

• Would it be possible to have manual cell delimeters? Something like:

  ##
  cell here
  ##
  

Edit: Sorry for the mess with the empty issue.

The current case is:

if there is a block of code (say 10 lines) is folded before the executing line, then the output window will be shifted downwards (10 lines). -------- test.py ----------- print('hello') # if execute this single line there, it works just fine

+-- 10 lines: ..... ---- # there are 10 lines being folded

print('hello') # if executing this single line, the output window would be at the bottom. (being shifted downwards 10 lines)

--------end test.py ---------------------

Hint of duplicate this issue, set the vim folding method to be "manual" and press zf after selecting the lines in visual mode

vim.opt.foldmethod = "manual"

So the essential issue would be when there are too many lines folded, no output window would be shown.

Hi,

hope everyone is doing ok. I am currently configuring my setup in AstroNvim, but I am having a little trouble with the debugger dap. I want to debug a big project, and I interact with it via a Notebook but it isn't working for me since magma ignore breakpoints. Thanks, any help will be appreciated.

Is your feature request related to a problem? Please describe. Taking inspiration from VSCode, it would be nice if there was a separate buffer for displaying plots.

Describe the solution you'd like This would be a virtual buffer or something like this that would allow you to maybe split things vertically then have your code file on say the left side, and then the on the right side be maybe a split horizontal that has a Plots buffer and a REPL buffer.

Describe alternatives you've considered I already keep Jupyter Console open in my tiling window manager but it would be nice to have all this integrated into Neovim

nbdev provides some excellent tools for developing with notebooks - particularly their solutions for working within a git repo.

However, my choices for working with it at the moment are:

• Use jupyter lab
• Use VS Code (https://code.visualstudio.com/docs/datascience/jupyter-notebooks)
• Translate between .ipynb and some other format so I can use neovim

I'd really like to use the .ipynb files directly within neovim and take advantage of the work that nbdev has done.

Magma is by far the most usable tool for neovim/jupyter integration that I've used to date. Is it feasible to add support for the .ipynb format without the need for any translation?

I can see some work done by https://github.com/ahmedkhalf/jupyter-nvim for viewing .ipynb files. That works nicely for me, but the project seems dead and hasn't gone as far as magma.

Closes #74

Jupyter supports any kernel, not just python's. That makes it usable for other languages, such as C# and F#. To use them, you have to make its output mimetype text/plain, that's where we need MagmaEvaluateArgument. Example of this command:

:MagmaEvaluateArgument a=5;

That will assign 5 to variable a in current context.

I also added an example of vim commands to add for kernel initialization. That makes it easier to use with, say, telescope. And by default it overwrites mimetype to text/plain for C# and F#.

Note that I merged @LoipesMas into my fork to make things easier for myself.
