Aider is such an awesome project! I didn't know about it until I read this comment. I also wanted a way to provide my code as context from within the terminal without having to copy and paste back and forth. The tool I wrote (llmo) seems pretty similar to yours, although it uses the Textual library and Rich.

I'm really excited to try out aider, thanks for making it!
