Svn2git backups tags

[John Lawlor]

Hi Nicolás

Thanks for your reply. It was really helpful. I am trying to just match
.project and a file called build.xml so I guess that would become:

match /Labs/ChattyApps/(.*.project|build.xml?)$
  repository /Labs/ChattyApps
  branch master
  prefix \1
end match

I will give that a try and see how it goes.

Thanks again,
John

If I remember correctly, svn2git will take the part of the SVN path
that was *not* matched by the regex and use that as the path in the
new git repository. For example, if you have "match /Labs/ChattyApps/"
and it's applied to "/Labs/ChattyApps/blah.xml", it will remove the
matched substring ("/Labs/ChattyApps/") and create a file called
"blah.xml" in the git repository.

If you're matching files instead of directories, this means you're
matching the *whole* path, and after removing the matched substring,
there is nothing left. svn2git will try to create an empty filename in
git, and git-fast-import will give an error.

The trick to match individual filenames is:

match /Labs/ChattyApps/(.*.project|.xml?)$
  repository /Labs/ChattyApps
  branch master
  prefix \1
end match

This will use the parentheses-captured part of the regex (the
filename) as the prefix, append the substring not matched by the regex
(which is empty because the regex matched everything), and use it as
the git path.

By the way, what filenames are you trying to match? That regex may
need some work... For example, note that ".xml?" means any character
(only one), followed by "xml" or "xm".
