I hate to bring this up in this thread, primarily because I cannot
see how to make it mesh well with the "submodule spec lets you
specify a group of submodule with labels", but for completeness of
discussion, I'll mention it anyway.
Instead of specifying "all files written in Perl" to work on by
giving a pathspec with three elements, e.g.
git cmd -- \*.perl \*.pl \*.pm
I've often wondered if it would be a good idea to let attributes
file to specify "these paths form the group Perl" with something
like:
*.pm group=perl
*.pl group=perl
*.perl group=perl
*.h group=c
*.c group=c
and say
git cmd -- ':(group=perl)'
instead.
The reason why I suspect that this may not work well with submodule
labels is because submodule labels (or any attribute we give via
.gitmodules to a submodule) are keyed by a submodule name, which is
the primary unchanging key (so that people can "mv" a submodule in
the context of the toplevel superproject without losing track of
submodule identity), not by paths to submodules, while the "group"
thing I want is merely a short-hand for pathspec elements and wants
to be keyed by paths.
But there may be somebody more clever than I who can come up with a
way to unify these two similar concepts without confusing end users.
