Add Highlighting

[ian-andrich]

Please consider adding highlighting to the shared code editor in SWISH.

This will help when programmers are collaboratively editing code and just want to call attention to a piece of code.

Hmm.... you know, this could be abstracted to any piece of text, and extended to collaborative drawing (eg circling something).

As yet, there is no shared editor. That is surely part of the plan. What exactly do you have in mind? Maybe associate the editor selection with a chat message? So you can select text, chat something about it and the chat message gets a button to show the corresponding selection? Ideally that means you should also be able to suggest a change. Possibly we can allow a user to perform local edits and send the diff as a chat?

well, This came out of my asking Ian to think of other use cases. He suggested shared highlighting. That seemed like a reasonable thing to stick in the pot - a way to select a block of code so you can say to the other programmer 'hey, this code has blah blah problem' and have them know what you mean.

I think it is a promising idea. Would require something in CodeMirror that acts similar to the normal
selection but is distinct (I guess).
