Are people using Pyvim as their main editor? #127

I really like the idea of this project. I'm curious if people are using Pyvim for their main editor. How does it compare to regular Vim in daily usage?

Hi there. I've just discoverd this project. I would love to try help it to get as close to vim as possible.

This project should have a sub-reddit.

No, although it's wonderful, it chokes on files that have 10,000 lines of code upward. Native vim doesn't choke on these. I think it has to do with the way prompt_toolkit handles syntax higlighting via pygments; and that it's not cacheing it as well as it could (because it slows down to unbearable speeds when you give it enough code at a time; vs vim which seems to maintain a constant speed regardless of how many lines of code are in the file you're editing)

It is not so much the syntax highlighting that makes it slow.

It's the way the document content is stored. In prompt_toolkit, it's literally one Python string for the whole document. Every insertion of a character creates a new string. In order to make it more efficient, we should have a better data structure. But this would be an enormous refactoring, I don't think anyone is willing to attempt right now. Feel free to look into that.
