- Arbitrarily many authors can edit the same file simultaneously.
- All syntax-highlighting modes CodeMirror provides are supported,
- as well as most of the visual themes.
- Author attribution is done by decorating text with color-coded underlining.
- Open files from local file system using the HTML 5 File API.
- Tries to guess filetype from file extension or MIME type.
- Line Wrapping optional.
- Save files to disk using Douglas Neiner's Downloadify (uses Flash since there's no reliable HTML 5 solution).
- Documents expire a set amount of time after last access (default two weeks, using Redis expire).
To roll your own copy, install Node.js and SocketStream at version 0.2 (which currently still should be default version available on npm). To test it simply run socketstream start
And head to 0.0.0.0:3000.
I chose a rather simplifying and (to my mind elegant) approach to operational transformation (i.e. making sure that concurrent edits get integrated at the right place in the document). You can read up on it at my weblog.
