Query for certain branches, but not the rest

Query for certain branches, but not the rest

[Felipe Contreras]

Hi,

Suppose I have these branches:

  fc/feature-a
  fc/feature-b
  master
  next

I want to show this: fc/feature-a fc/feature-b ^master ^next. I can do
'git log --branches=fc' to show the branches that begin with fc/, but
there's no way to specify the rest. If they were under a prefix, I
could do '--not --branches=prefix', but they are not.

Anybody knows a way to query branches that don't have any prefix?

It appears this works:

% git for-each-ref refs/heads/*

But I would like something parsable by rev-parse.

Any ideas?

Cheers.

I don't think there is a way. `--branches` can take a pattern (and there
is always `--glob`), but we do not pass FNM_PATHNAME to fnmatch, so "*"
will match across `/` boundaries.

You are stuck with:

  git log --branches=fc --not $(
    git for-each-ref --format='%(refname:short)' refs/heads |
    grep -v /
  )

which is at least robust due to the restrictions on refnames (i.e., no
whitespace).

As an aside, I noticed that:

  git log --branches=does-not-exist

will see that we matched no refs and fall back to showing HEAD. That
seems a bit surprising to me.
