is it possible to link SVN repository files so that a file is actually a reference to another repository's file?

Question

I can see some potential difficulties with this concept but the idea is,

I change a file in Repository A and commit, Repository B has a file that is a link to a file in Repository A, I click update on the file in my working copy for repository B, and i recieve the updated file from repository A.

Answer 1

Yes, for directories anyway

See this section on svn externals.

Update: Good call also by basszero but note that the questioner almost certainly does not have an svn 1.6 repo, so he can't do it with files.

Answer 2

This is easy to do with "external" links in your subversion repository.

Personally I find this is very useful for incorporating open source libraries into my code (Codeplex, Google Code, etc...).

Search for "svn:externals" to find documentation on the details

Answer 3

If you're lucky enough to use subversion 1.6, you can have external links for both directories AND files
