I used to use ClearCase in a past life (3.0 - 6.0). I haven't missed the ability to diff dirs. You might be stuck on doing things the CC way instead of learning the Subversion paradigms. It's going to be frustrating for a little while (it was for me.)

What are you trying to do that requires diff'ing the contents of directories?

You want to read up on peg revisions: http://svnbook.red-bean.com/en/1.7/svn.advanced.pegrevs.html

You don't need to specify the rev for each path in the component, e.g. "/view/foo/path_at_1/foo_at_2/bar_at_3/j.java_at_5". In SVN, the rev number is global, so you just "/path/foo/bar/j.java_at_5".

Use "svn export" (or for individual files, "svn cat")

You'll need to use a peg revision, e.g. "svn copy svn://..../path/foo.java_at_1234 ." To find the revision that the file was in can be tricky if you have deleted a parent dir. In the average case, you can run "svn log -v -q ^/path/to/branch > log.txt". Then search the text file for your missing file to get the revision. You can also use "svn log -v -q | egrep '^r|\/foo.java'". Worse case (you deleted a parent dir), you'll need to run the 'svn log' against the root of the repository (svn log -v -q ^/).

To re-emphasize, I'm very serious about the need to stop trying to apply CC paradigms to SVN. It's frustrating, and, in my experience, the CC way of doing things didn't provide significant advantages in (or over) SVN.
