Source Code

We have a convenient web interface if you’d like to browse the WordPress source and inline documentation.

The WordPress source, licenced under the GNU General Public License version 2 (or later), resides in a Subversion repository at core.svn.wordpress.org.

WordPress compresses core JavaScript and CSS using the latest version of the YUI Compressor. The uncompressed development versions of these scripts reside in the core repository. The source code for any program binaries or compressed external scripts that are included with WordPress can be freely obtained from our sources repository.

The wp-admin/js/revisions-js.php file is available in human-readable form here.
