feat(helix-view): dynamic line numbers

[The0x539]

This is a configuration that I've carried with me from Vim to Neovim to Kakoune.

This implementation was remarkably easy to figure out; in the past, it had always been unusually difficult and relied on various mode change hooks and what not.

Can I know how did you do this in vim, neovim, and kakoune?

Although this seemed useful as a default (at least from what I see given that relative number is only showing at the time it is useful), it seemed oddly specific.

I think you also need to update the book configuration.md but if you just put dynamic I doubt readers understand what it meant.

I'm pretty sure I originally found my original Vim version online on some "tips and tricks" wiki that I could swear was on Wikia, but I can't find it now. Maybe I'm misremembering and never had it in regular Vim; a quick search of the master (old) branch of my dotfiles repo suggests as much.

This, after some refinement, is how I did it in Neovim, and this mess, of my own invention, is how I do it in Kakoune.

Yes, good catch. I'll do that now.

EDIT: I may have found it.

Should we just make this the default behavior of relative line number? I can't imagine you'd want relative line numbers in unfocused windows so the new behavior seems a lot better

Let's make this the default behavior of relative!
