Subversion: Change all static externals from operative to peg revisions?

Question

We have some shared libraries, and these are referenced as static externals in all tagged versions of our different projects.

After reorganizing the directory structure of our shared libraries, I see that all tagged versions now gives an error. I realised that the externals should have been referenced by using peg revision (@X) instead of operative revision (-r X).

We have hundreds of tagged versions, and inside these there are two-three different external references.

How can I recursively change the external definitions from operative to peg in my /main/projectX/tags/ folders? I imagine I will need some sort of shell script to do the job.

We solved this by running:

svn propget svn:externals -R http://repoURL

The output was used as a starting point for creating a svnmucc control file with the following content:

propset
svn:externals
^/external-source external-target
http://repoURL
propset
svn:externals
^/external-source2 external-target2
http://repoURL

And this was applied to the repo by running:

svnmucc -m 'Changing externals from operative to peg' -X controlfile.txt

The output of propget was quite different from the svnmucc format, so I had to do some manual work, and wrote a little PHP script to do most of the repetative work.

The only thing I was not able to do using svnmucc, was multiple externals on the same folder. Apparently, svnmucc cannot set multi-line properties on the same target. But we only had a few of those in our repo, so that was OK to fix manually using the TortoiceSVN repo browser.
