I got this error while attempting to do a MagmaLoad:

Error detected while processing function Jupyter[8]..remote#define#CommandBootstrap[5]..remote#define#request: line    2:
[Magma] Error while doing Magma IO: Incorrect type for key 'execution_count': expected int, got NoneType

After checking the corresponding json, there was effectively a 'execution_count': null, and I managed to fix the issue by adding manually an unused number.
My guess is that this was caused because I did a MagmaSave while a cell hadn't finished running, but I feel like this should not cause an error, and magma should be able to load information about a partially executed cell and display it as such.

Can the plugin be made to work with progress bars such as tqdm that rewrite the buffer?
Thanks

Currently it seems to use g.python3_host_prog. Which i feel is okay/good for the plugin itself (I setup a venv for neovim to run plugins inside). But for the kernel it should use the virtual environment activated when python was launched or add a command that chooses which python interpreter to use (similar to vscode)

It would be nice to have a way to jump to the previous/next cell, or even to cell number n

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

They need to be somehow accessible through vimscript; however, this is probably best done with vimscript functions with "internal" (or similar) in their name.

The relevant commands are:

• MagmaClearInterface
• MagmaOnBufferUnload
• MagmaOnExitPre
• MagmaTick
• MagmaUpdateInterface
• MagmaEvaluateFromOperator

Is your feature request related to a problem? Please describe.
Add documentation in vimdocs format so it can be accessed via :h magma.

Describe the solution you'd like
Ideally there is a way to transpile markdown to vimdocs, so the README can be reused. I'd have to look into that.

Describe alternatives you've considered
Always opening the README, this is non-ideal.

Additional context
I found these two transpilers with a quick google search, but I'd have to look into the a bit more, if this feature is something you would like in the project.

floating output window stays and will not disappear
in cases that I reevaluate the cell.

Thanks very much to the project maintainers, this looks very promising!

Unfortunately I cannot use this as I use MacOS and ueberzug does not work on MacOS (see #15). However, I was wondering if it would be possible to still use magma-nvim without ueberzug, with the caveat that images cannot be displayed?
As it stands, I can't even try out the plugin because :MagmaInit complains that ueberzug is not installed.
Or maybe I underestimated how much the project relies on ueberzug?

Thanks in advance for the consideration.

Hello and thank you for the project!

I followed the instructions and none of the commands showed whatsoever.

Checking the health shows that everything is installed correctly.

Does anyone have an idea of why this is the case? Thank you!

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.

GIF demos will be added to this issue so that we have an URL to insert in Markdown which does not pollute the repository.

Can we add a command to rerun the current cell the cursor is in?
This would be awesome :)

Additional context
I'm using pyenv and i have vim.g['python3_host_prog'] = '~/.config/pyenv/shims/python3' set in my config file . Note that i have all the dependencies up and running well with no problems
If i use my system's python then i will have another problem with ueberzug since it dosen't seem to work under python 3.10

I wonder is it possible to add an option to hide the output. I think letting the output be automatically shown but some outputs contain many warnings, in which case, an cmd that one can hide the output would be nice.

It would be amazing if some way of persisting cell definitions between executions of nvim can be cooked up.

Hi,

I would like to see a variable explorer feature in your plugin. Please check https://www.reddit.com/r/vim/comments/hl0paq/finally_figured_out_how_to_work_in_vim_with/ for more detail.

Thank you.

Describe the bug
Thanks for your work on this exciting plugin!

When initializing :MagmaInit and choosing the kernel (python3) I immediately receive the following error:

Error detected while processing function MagmaUpdateInterface[1]..remote#define#request:
line    2:
Error invoking '/root/.local/share/nvim/site/pack/packer/start/magma-nvim/rplugin/python3/magma:function:MagmaUpdateInterface' on channel 11 (python3-rplugin-host):
ch 11 was closed by the client

The actual value of the channel changes between runs, but the error is the same. Once I press enter it starts repeating this message everytime I try to do anything:

Error detected while processing function MagmaTick[1]..remote#define#request:
line    2:
Error invoking '/root/.local/share/nvim/site/pack/packer/start/magma-nvim/rplugin/python3/magma:function:MagmaTick' on channel 11 (python3-rplugin-host):
Invalid channel: 11

which renders my nvim instance useless.

FWIW :checkhealth reports that everything is fine (before the init, of course).

Desktop (please complete the following information):

• OS: Ubuntu 18.04 [inside a docker container)

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.

Use c31b19e to implement support

Hi, I found while running long text the output is impossible to read. Maybe there are some settings to fix it, or plan to extend it?

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

Im trying to set up a workflow, where I automatically load magma for *.jupyter files, and get consistent behavior between opening new files and reopening old files. Something like this:

function! MyMagmaInit()                                       
        setlocal filetype=python                              
        set syntax=python                                     
        MagmaInit python3                                     
        MagmaLoad                                             
endfunction                                                   
                                                              
augroup magma                                                 
  au! BufRead,BufNewFile *.jupyter call MyMagmaInit()         
  au! BufWrite *.jupyter MagmaSave                            
augroup end                                                   

However, Im getting a clash between MagmaInit and MagmaLoad when reopening a file, as MagmaLoad tries to init a second time:

Error detected while processing function MyMagmaInit[4]..remote#define#CommandBootstrap[5]..remote#define#request:

[Magma] Magma is already initialized; MagmaLoad initializes Magma.                   

Also, when opening a new file, the MagmaLoad fails gloriously.
Any ideas how to solve this? Can we add a way of checking if a file has saved state, reload it id it exists and if not init magma?
Maybe a new command, something like:

MagmaLoadInit('python3')

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

Describe the bug
When I ran :MagmaEvaluateLine, a popup showed up with message Out[5]: ✓ Done but a plot didn't show up. I had run :checkhealth and all was ok.

To Reproduce
Steps to reproduce the behavior:

1. I wrote this code:

import numpy as np
import matplotlib.pyplot as plt

 x = np.linspace(-10, 10, 1000)
y = np.sin(x**2)

plt.plot(x, y);

2. I ran :MagmaInit then chose python3.
3. I ran all the line using :MagmaEvaluateLine.

Expected behavior
The line plt.plot(x,y); should show a plot, but it only shows Out[5]: ✓ Done

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

I want to make some buffer local bindings when I initialize magma inside the buffer. Right now I do it by defining my own command that calls MagmaInit and sets up the keybindings, but that needs me to remember to run my command and not MagmaInit.

Maybe a user event for autocommands would be good?

Currently, when I load a magma save, I have to manually reevaluate all cells in order to get my python environment back to where it was. I think it would be convenient to have a command MagmaReevaluateAll that would loop through all cells, most likely in document order (or perharps, as an option, in execution_count order, and reevaluate each one, waiting for it to be finished before going to the next one.

Also, it feels related, but it would be nice to have a way to jump to the next cell, or even to cell number n

To Reproduce
Steps to reproduce the behavior:
Start magma, execute a cell and try to save the buffer

Expected behavior
no bug...

Is your feature request related to a problem? Please describe.
Not precisely a problem but it would be great to have the option of defining cells manually (e.g using # %%) so that everything is in the same file and there's no need to save and load another file whenever editing code.

Describe the solution you'd like
Add an option that either lets you use a predefined "marker" to define a new cell or lets you define your own marker.

Describe alternatives you've considered
Using visual selection and running the code to create a cell. However, if I forget to save or load the json file it will start throwing errors and I lose all the cells. I would prefer if I can define the cells myself using # %%.

Is your feature request related to a problem? Please describe.
It's sometimes useful to be able to read the whole output from a cell and in that case the limited space that a pop-up offers is not enough.

Describe the solution you'd like
Perhaps some way or scrolling the pop-ups or to request opening the output in a new buffer where you can read it and then close it.

Is it possible for this to support remote server?

This plugin is literally all I ever wanted. Can't tell you how pumped I am. However, I'm, like so many, running Mac so this doesn't work right now.
(Not telling you anything new here probably but ueberzug isn't available on Mac)
Looks like #14 is a very good possible solution.

Describe the bug
When I run code to show a matplotlib plot, the output image becomes larger after I do zt (to move the code up)

Expected behavior
In the GIF (given in the readme of the repository) , the output plot appears to be the same in size when scrolling, Is this some option that I set in my config?

Screenshots
If applicable, add screenshots to help explain your problem.

After scrolling up:

Is your feature request related to a problem? Please describe.
Sometimes I might start long running cells and notice a mistake in the code while it's running, interrupting the kernel saves me from deinitializing and reinitializing magma. Similarly, sometimes the kernel gets into a failure state regarding one cell or one might get rid of memory-heavy variables that the kernel has loaded, in that case restarting the kernel might be necessary.

Describe the solution you'd like
Two commands, MagmaInterrupt and MagmaRestart, that do the afforementioned things.

Describe alternatives you've considered
The only alternative I can think of is to use MagmaDeinit and MagmaInit to get a fresh kernel.
Another thing worth considering is to add MagmaStart and MagmaStop functions that (re)start or stop a kernel, also a flag or separate command for restarting and clearing all output together might be a nice addition (this could even be nice default behaviour for MagmaRestart.

Additional context
I have already implemented this feature in my fork, have verified that it works, and will open a pull request.

Thanks for this great project!

This project so needs into the community! I hope that you will be maintaining this project!

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

##
1st cell here
##
2nd cell here
##

Is your feature request related to a problem? Please describe.
Having magma enabled makes scrolling slow, especially in larger cells and files.

Describe the solution you'd like
I didn't have time to look into it in more depth, but MagmaUpdateInterface should be made as performant as possible, maybe caching and only moving certain elements, or not be called on every curser move event. Doing slow computations asynchronous might also be possible.

Describe alternatives you've considered
Simply disable the autocmd.

Additional context
I'll probably be able to look into it a little at the end of next week.

vim.ui.select is a lua function that is overridable by the user for so that the user can create alternate uis

Describe the solution you'd like
Call the lua function vim.ui.select instead of the viml function inputlist. I guess the main problem is I don't know if lua can be called from python.

A related would be to include a Telescope extension so we can search for the kernel we want to init. This might be more convenient for users, especially if they have a lot of virtual environments with different kernels

Is your feature request related to a problem? Please describe.
I would mostly like to understand, how you handle virtual environments, since I have not been able to fully grasp this.
Consider the following:

• I have a hard-coded g:python3_host_prog=~/Installations/pynvim/venv/bin/python as suggested in :help python-virtualenv
• I use virtual environments in all of my local projects
• when starting a kernel via :MagmaInit, I would like that it starts the kernel using the active virtual environment

Describe the solution you'd like
As said above, I would like the kernel started by Magma to use the currently active virtual environment, from the shell in which Neovim was started.

Describe alternatives you've considered
I would like to avoid having to install all the Neovim-related python packages in every environment and remove the python3_host_prog setting, but I assume that this would be an alternative.

Additional context
Years ago, I implemented a similar project, deuterium, but it has less features than yours and is currently so out-of-date, that I was looking at alternatives before trying to revive it. I found your plugin to basically do everything I want, except the handling of virtual environments.

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
ubscriptable
Traceback (most recent call last):

  File "<frozen importlib._bootstrap>", line 702, in _load

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.

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.

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

Screenshots
If applicable, add screenshots to help explain your problem.

Desktop (please complete the following information):

• OS: MacOS 12.5
• Browser: N/A

This seems like a silly question, but how do you get started using this plugin? I had supposed that I would just open a .ipynb file but nvim shows it as an unparsed text file with all the delimiters etc. visible. Are you supposed to start with a blank file and then work from there?

Sorry if I'm being an idiot!

For the following code:

import numpy as np                                                
import matplotlib.pyplot as plt                                   
                                                                                                                
x = np.random.rand(10000)                                         
plt.hist(x)                                                    

I get the following error:
