Getting the SVN revision number in Ruby

rev = `svn info`.match('Revision: (\d+)')[1]

That bit of Ruby code will return the Subversion revision number of the working copy it is run in.

`svn info` returns

Path: .
URL: http://svn.yourdomain.com/trunk/

The regex bit (.match(’Revision: (\d+)’)[1]) then returns the 894 number from that string.

(Thanks to Dela for the regex.)
