Re: Tree-internal real links

Thanks for the tip. I didn't know about svn:externals.

It seems to support pulling in trees from other repositories. While
that by itself is a good thing, I think the design keeps it from
solving my problem.

What I am really looking for is a format of a property like what's
below (we'll call it svn:internals). Suppose I had a tree that looked
like this:

with files in each directory.

The svn:internals property would be:

$ svn propget svn:internals /projects/calc
/resources -r21

And if I checked out /projects/calc, I could do so in a way that would
PRESERVE the tree's structure in my own working copy, rather than
building the other directories into Calc, which is the behavior of

$ svn checkout http://svn.example.com/projects/calc
A projects/calc
A projects/calc/Makefile
A projects/calc/integer.c
A projects/calc/button.c
Checked out revision 148.

Fetching internal item into /common
A common/some
A common/other
A common/files
A resources/andmore
A resources/files
Checked out revision 21

So the working copy tree would be a subset of the repository tree,
with all the directories checked-out mirroring the directories in the
repository. What I'm trying to get away from is having to put the
"common" and "resources" directory, which are common to many projects,
as subdirectories inside the "calc" project. Otherwise a check-out of
the entire repository will get duplicate code into the working copies
-- as many copies of the common shared libraries as there are

Does that make sense? Is there no way to mark that one directory
should bring other directories with it, without making those
directories have to belong within the first?
