Performance is truly impressive. And I really love how small the codebase actually is. I've been dreaming about writing my own text editor for quite some time. This will really help me to get started, thanks a lot nsf!
p.s. panic on opening a directory isn't really a best way to say that you don't support viewing directories...
I agree this panic is quite annoying sometimes. Will make a proper error message when I have time. A very minor issue at the moment. You see I'm not really actively working on it anymore, I use the godit for all of my text editing tasks and if some feature/bug annoys me a lot in godit - I fix it. Directory opening by accident happens sometimes, lol, and when you see a panic message, you panic as well, but then phew.. :)
