I made something like this though only works in Vim (but not nvim). You can highlight text and send it to a :term and it gets updated as you update the code in the buffer. It’s pretty hacky—it just copies the code from the buffer to a tempfile then import_filess it in the term window (adding that line to your IEx history). In any event, it’s possible

I would love to be able to connect to a running REPL a-la clojure. It would allow for more flexibility than LSP (though of course back to editor-specific implementations). There’s been discussion about it around here but I don’t think there is much movement around it (I was feeling motivated but then moved on).

EDIT: I forgot I made a screencast about it—it’s my first and only screencast so be nice (lol).

That’s cool! I made a Neovim plugin that does something similar - it sends the character to the term and adds a line break at the end to execute the command.

Do you use your Vim plugin often? I also have the dream for better interaction with IEx but unfortunately I don’t have much time to build something right now and I end up typing directly in IEx more than I would like to.

I ended up not using it too much since the auto-update for mix projects arrived weeks later. I also use tests a lot to run random stuff. It was largely more of an experiment and just showed in into my plugin But ya, an actual connected iex is the dream.
