xray VS superstring

Hadn't them already abandoned another one before?

Im super glad to see that this is probably the continuation of atom-xray and that the devs are still doing new projects! The move from web to full Rust is interesting, I wonder how it will perform.

Even before Microsoft bought them they were focusing on a completely new editor: https://github.com/atom-archive/xray. That's since been scrapped, and from the contribution graph on atom it's pretty clear the only remaining development is from community volunteers.

Before Microsoft bought GitHub and killed Atom, they were working on Xray[1] & Memo[2]:

> Memo is an operation-based version control system that tracks changes at the level of individual keystrokes and synchronizes branches in real time.

Emacs does not use ropes. Neither does Atom. Emacs uses gap buffer, while Atom has got specially designed, linked data structure, that seems to be inspired by the both ropes and piecewise table. But it is of little importance. Atom was doomed to go extinct by the time Microsoft purchased Github. Its popularity was already in decline, and there certainly isn't any reason to pour resources in development of two text editors based on Electron.

I was misremembering, it's Atom which made some C++ libraries for text handling and string processing because of performance issues (https://github.com/atom/superstring and another i think ?)
