Like this question, but without the need to actually query the SVN server. This is a web-based project, so I figure I'll just use the repository as the public view (unless someone can advise me why this is a bad idea). I assume this info is in a file in the .svn folder somewhere, but where, and how do I parse it? I want to do something like what SO does, having the revision in the bottom-right corner.

Code in Python or PHP appreciated if you have it on hand, or just a point in the right direction.

Subversion includes the svnversion tool for exactly this purpose. A working copy may actually have local modifications, or may consist of a mix of revisions. svnversion knows how to handle that; see the examples in the linked documentation.

You can invoke svnversion from python like this:

import subprocessdef svnversion():p = subprocess.Popen("svnversion", stdout=subprocess.PIPE, stderr=subprocess.PIPE)(stdout, stderr) = p.communicate()return stdout
