Feature Request: Improve REPL Readability (Font/Color Support)

[kaikikokuke]

Hi,

First off, thanks for the amazing work on this project! It has been a game-changer for my workflow, allowing me to fully embrace Neovim instead of alternatives like VSCode or JupyterLab.

I was wondering if it would be possible to enhance the REPL experience by adding support for font customization (types, sizes) or color differentiation. I sometimes find it challenging to distinguish between input and output, as well as quickly identify data types. Perhaps something like how IPython or bpython handle syntax highlighting and formatting?

This would greatly improve usability, especially when working with large or complex outputs.

I'd love to hear your thoughts, and I’m happy to test any proposed solutions.

Thanks again for all your hard work!

I believe iPython could do this with this. You can set the repl_definition for python like this

      repl_definition = {
        command = { "ipython", "--no-autoindent", "--colors=Linux" },
        format = require("iron.fts.common").bracketed_paste_python,
      }
