documentation VS xi-editor

The example from the PureScript documentation is:

Filippo: With Haskell knowledge, reading PureScript documentation was enough.

I'm trying to get a better grasp on the type system of purescript. One thing I'm struggling to fully understand is how the so-called "kind system" works. The language reference is very brief about it.

purescript uses (_ - 5) for that operator section, which i'm not a total fan of, but it's at least unambiguous; agda would write it as _- 5

The one page you should add to the documentation is "differences from Vim".

For example, https://github.com/purescript/documentation/blob/master/lang... makes picking up PureScript as a Haskell programmer much easier than having to read all of the documentation and do the diff yourself.

More info can be found here: https://github.com/purescript/documentation/blob/master/guides/Getting-Started.md

Was confused until I realised I'd confused Zed, with Xi[1] which is also rust based, and which incidentally has a frontend called "Xim"..

Also there's a wiki-editor (like Tomboy[2]) called "Zim"[3].

Project site linked from the GitHub[0] is https://xi-editor.io. Linked doc is a mirror of this[1], which was afaik originally written by Raph Linus.

Is there a canonical source for this part, by the way? Xi copied the logic from Android[1] (as per the issue you linked downthread), and I vaguely remember that CLDR had something to say about this too, but I don’t know if there’s any sort of consensus here that’s actually written down anywhere.

This is pretty much how copy-on-write ropes work. Check out xi-rope, Ropey or crop, they're all built using B-trees and implement the behavior you described.

Helix is awesome, though once Lapce (spiritual successor to Xi editor) gets the Helix/Kakoune editing model, I may have to jump ship

Maybe take a look at the Xi editor (https://xi-editor.io/) (written in rust I think) that uses a client server architecture.

Have a look at what Lapce uses. The editor is coming along nicely, and iirc, they use the Xi editor as a plug-in.

Raph Levien posted a retrospective about using CRDT’s for collaborative editing in xi-editor here [1]. His conclusion is

“I come to the conclusion that the CRDT is not pulling its (considerable) weight. When I think about a future evolution of xi-editor, I see a much brighter future with a simpler, largely synchronous model, that still of course has enough revision tracking to get good results with asynchronous peers like the language server.”
