context.vim VS code-cells.el

There are a couple of plugins that do this.

For vim: https://github.com/wellle/context.vim

For neovim (much higher performance in my experience): https://github.com/nvim-treesitter/nvim-treesitter-context

I believe there's now also a VS code plugin for the same behavior, but I don't know what it's called.

I think that something like this https://github.com/wellle/context.vim is what you are looking for

https://github.com/wellle/context.vim does something very similar to what you are asking for. You can probably tweak it according to your needs.

I've recently started using vscode after using vim for many years, and one thing that I miss is the context.vim plugin which shows the function signature at the top of the screen when you scroll.

context.vim for those not using treesitter

I ran across context.vim https://github.com/wellle/context.vim, which is basically a sticky header, where your cursor is.

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
