code-cells.el VS AstroNvim

code-cells: Utilities to work with “lightweight notebooks”, that is, source code which is split into cells by special %% comments. Also allows you to transparently edit Jupyter notebook (ipynb) files.

Emacs, Sublime Text 3 and Atom Pulsar can all do this with arbitrary Jupyter kernels with the emacs-jupyter/code-cells, helium and hydrogen packages, respectively.

I've been using code-cells together with emacs-jupyter, the combination of the two lets you work pretty much identically as you would in Atom with Hydrogen, Sublime with Helium, or VSCode with the Jupyter Python extension; you just delimit code cells with #%% and execute in a separate Jupyter REPL buffer. It does require some getting used to the key bindings though (or some tweaking to make it more similar to what you're used to).

I use a similar setup in Emacs with code-cells.el [1]. VSCode had a tendency to choke rendering large interactive graphs in-line, so if I was needing to view in a separate process anyways a little elisp turns "write last IPython output to a tempfile, open, move to workspace N" into a keybind.

I use the simple but very convenient code-cells package to run python cells. E.g. with the Spyder IDE, the cell where the cursor is currently in has a different background color, and I'd love to have that in emacs. Would you have any idea on how to do that?

For scripts with cells there are a couple of packages. Mine is this: https://github.com/astoff/code-cells.el

Not sure of all of your use cases but this is my sorta my workflow when working mobile using termux and termux-x11. i use i3 WM, AstroNvim.

One of the demo pics in the GitHub README seemingly shows a file navigation panel. Since I haven't seen any config which reproduces this feature, do you any ideas as to how it was done? I'm only aware of two packages with similar functionality (nvim-navbuddy and dropbar) but they do not display breadcrumbs as a side panel.

If you don't have much clue, this might help you. https://github.com/AstroNvim/AstroNvim/blob/main/lua/plugins/telescope.lua

My current favorite is AstroNvim: https://github.com/AstroNvim/AstroNvim, with an awesome introduction video: https://youtu.be/GEHPiZ10gOk

You really want nvim. And if you don't already know, look at astronvim. It has all the IDE-like features, and whatever new plugins pop up for nvim, the community will try to include configs for them. The community packs of Astronvim are arguably its best features. https://github.com/AstroNvim/AstroNvim
