sapling VS rustpad

Basically, when you say 'structural editing', do you mean making an AST for every kind of input and having a modal command language that permits traversal and editing of that AST. Like what sapling https://github.com/kneasle/sapling is attempting to do ?

For example, you can edit the AST directly: https://github.com/kneasle/sapling

There's a text editor being developed that edits code based on nodes of its AST representation - https://github.com/kneasle/sapling

Take a look at https://github.com/ekzhang/rustpad

I'm looking for software similar to https://rustpad.io but with login and password. Docker would be nice :)

You could try rustpad

Looks pretty similar to https://rustpad.io/

Awesome! I requested this in rustpad but it was closed with wontfix. I suppose it is out of scope of rustpad but I'm really glad to see that there's this project to add it.

Just adding an example to the other side, I wrote https://rustpad.io/ in Rust, which is a collaborative text editor that uses WebSockets and resolves edit conflicts in real time using an operational transformation algorithm. It's a fairly complex bit of logic. But I actually thought Rust was the best language for this application because of performance, data race-safety, Serde, and the borrow checker. (My second choice would have been Go with stress tests run under `the -race flag.)
