Subject: Emacs + Etherpad compatibility? (was: Question collaborative editing.)
Date: Fri, 02 Oct 2020 13:48:06 -0500	[thread overview]
Message-ID: <87blhkbh21.fsf_-_@red-bean.com> (raw)
In-Reply-To: <20200930131931.scdkrx46vylpi4c3@Ergus> (Ergus's message of "Wed,  30 Sep 2020 15:19:31 +0200")

This discussion is exciting.  I regret that I don't have to work on actual implementation, but maybe posting this thought here can be a small contribution:

The fastest route to collaborative editing in Emacs might be to make an Emacs-side client implementation for the protocol used in Etherpad Lite.  

(I'll just call it "Etherpad" from now on, since it's the only actively maintained fork of Etherpad now as far as I know.)

Etherpad is browser-based and is the most widely-used free software collaborative editor.  It's been very successful.  The entities it operates on are already pretty compatible with Emacs -- it's basically plain text with some simple formatting: bold, italic, underlining, strike-through, simple bullet-point or numbered lists, authorship colors, and not much else.  (Even the authorship colors don't necessarily have to be represented as colors; that's just the optional display convention in Etherpad.)

The protocol used by Etherpad is EasySync -- see docs here:

https://github.com/ether/etherpad-lite/blob/develop/doc/easysync/easysync-notes.pdf

https://github.com/ether/etherpad-lite/blob/develop/doc/easysync/easysync-full-description.pdf

(Or just do 'git clone https://github.com/ether/etherpad-lite.git' and look in the 'docs/' subdirectory.)

Emacs can certainly display all the things Etherpad can display.  How hard would it be to implement an Emacs client library to handle the protocol?

Personally, that's where I'd start if I had time to work on this.  It would give us both real-time collaborative editing for Emacs, *and* Emacs users being able to real-time collaborate with non-Emacs users on the same document!  This would be an enormous win for Emacs.

Best regards,
-Karl
