Subject: is there a reason pre-commit.sample uses "git diff-index"?
Date: Thu, 31 May 2018 12:38:46 -0400 (EDT) [thread overview]
Message-ID: <alpine.LFD.2.21.1805311235410.15130@localhost.localdomain> (raw)
was going over some hooks and writing some tutorials for some of the
commit-related, client-side hooks, and was wondering (perhaps
stupidly) why the pre-commit.sample hook uses, as its last line:
exec git diff-index --check --cached $against --
^^^^^^^^^^
as in, could this not be done equivalently with just git diff, not git
diff-index? i just did a quick test and it seems to do the same thing,
but i've never taken a close look at git diff-index before so i may
just be clueless about some important distinction.
