svn2git rules regex

问题

I'm trying to reduce my ruleset for svn2git. My tree looks like this..

A/foo
B/foo
C/foo
D/foo

I want to put A, B, and C under a legacy folder and that works. I want D to be it's own top level folder.

My current rule is..

match /(A|B|C)/([^/]+)/
  repository myrepo
  branch legacy/\1/\2
end match

Is it possible to modify the rule such that D does not end up legacy without having to define another rule?

End result should be:

legacy/A/foo
legacy/B/foo
legacy/C/foo
D/foo

回答1:

Yes, it is possible. I'm not sure how svn2git RegEx might look like. However, this RegEx might create your outputs by simply keeping D/foo as is, and then only changing your other three inputs using two groups plus a middle boundary /:

^(A|B|C)\/(foo)

You can probably change your codes based on this RegEx.

I'm not really sure, but my guess is that you codes might change to something similar to:

match /^(A|B|C)\/(foo)/
  repository myrepo
  branch legacy/\1/\2
end match

It the code would work, it would probably work without ^:

match /(A|B|C)\/(foo)/
  repository myrepo
  branch legacy/\1/\2
end match
