Racket Operational Transformation

Implements Operational Transformation (OT) for Racket.

Inspired by the simplicity and elegance of the presentation in this blog post.

Installation

From the package catalog

Run

raco pkg install operational-transformation

Or, if you only want the library and not the demos,

raco pkg install operational-transformation-lib

From a git checkout

Check out the repository. Then, in the directory containing Makefile,

make link

Running the demo

Screenshot

Find a text file you wish to collaboratively edit. Let's call it foo.txt.

Make sure you don't mind if foo.txt is saved to disk! Each time a change is made by a connected client, the demo server saves over the file.

Start the server

Change to the directory containing foo.txt and run

racket -l operational-transformation-demo/server foo.txt

This will start a TCP server on localhost, port 5888 by default. Supply -p <portnumber> before foo.txt on the command-line to select a different port.

Start the clients

Then, run multiple clients. Start each client with

racket -l operational-transformation-demo/client localhost

Again, supply -p <portnumber> before localhost to select a different server port.
