Implements Operational Transformation (OT) for Racket.
Inspired by the simplicity and elegance of the presentation in this blog post.
Run
raco pkg install operational-transformation
Or, if you only want the library and not the demos,
raco pkg install operational-transformation-lib
Check out the repository. Then, in the directory containing
Makefile,
make link
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.
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.
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.
