Negation in refspecs

Mickey Killianey· Mar 5, 2014, 18:06 UTC · lore

Is there any syntax to support partial negations of refspecs, such as:

+refs/heads/*:refs/remotes/origin/* !refs/heads/dont-pull: !:refs/remotes/origin/dont-push

If not now, is negation something that might be possible/reasonable in a future version of Git, or is it difficult/unlikely to change?

No, it doesn't exist now. It's something that people have asked for occasionally, but I don't think anybody is actively working on it.

I posted a rough patch here:

  http://thread.gmane.org/gmane.comp.version-control.git/240997/focus=241057

about a month ago, but I do not have any immediate plans to take it further (that email details some of the issues). If you're interested in working on it, I think people are receptive to the idea; it just needs a clean implementation.
