This merges all the different files into one app.nix using nixvim
instead of the manual home-manager nvim management.
Behavior should be almost unchanged, with the following changes:
- Plugins now have defaults for my own personal sane default experience
- The highlighted line is now 81 instead of 80
- Treesitter plugins may not be integrated correctly
I'm sorry to say but I use 2 spaces instead of 4, and I prefer a line
width of 80, not 100. For that reason I'm disabling rust linting if the
language is enabled.
