Re: Fwd: Possibly nicer pathspec syntax?

Linus Torvalds [off-list ref] writes:

No. The thing is, "git diff" is relative too - for path
specifications. And the negative entries are pathspecs - and they act
as relative ones.

IOW, that whole

  cd drivers
  git diff A..B -- net/

will actually show the diff for drivers/net - so the pathspec very
much acts as relative to the cwd.

But that is not what I was talking about.  Let's simplify.  I'd say
for any command that acts on "everything" when pathspec is not
given, the two sets of actual paths affected by these two:

	git cmd -- "net/"
	git cmd -- ":!net/"

should have no overlap (obviously) and when you take union of the
two sets, that should equal to

	git cmd --

i.e. no pathspecs.

 2. I am not sure what ctype.c change is about.  Care to elaborate?

I didn't see the need for it either until I made the rest of the
patch, and it didn't work at all.

The pathspec.c code uses "if (is_pathspec_magic(..))" to test whether
a character is a short magiic pathspec character.  But '^' wasn't in
that set, because it was already marked as being (only) in the regex
set.

Does that whole is_pathspec_magic() thing make any sense when we have
an array that specifies the special characters we react to? No it does
not.

But it is what the code does, and I just made that code work.

Ah, OK.
