Yi is really nice, overall. The code is clean too.
I don't remember all of the issues, but there are a ton of small things that make the editor unusable to me. I used it for a couple of weeks, and I spent some time working on these issues, but never had PR-worthy code. Here's what I can remember off the top of my head:
- Startup time is very slow because of the way configuration works. In my local copy, I made a version without runtime configuration, and that solved this problem. This conflicts pretty badly with the whole architecture, so I didn't make a PR.
- :n :N don't work. Opening multiple files from the command line doesn't work.
- :cq doesn't work. I fixed this, but my fix was a hack, so I didn't make a PR.
- Operating on regions with '{' and '}' is off by one line in some directions.
- You can't replace regions with shell commands. For example, using '!}sort' to sort a paragraph.
