Subject: [PATCH v2] git-diff.txt: document return code of `--no-index`
Date: Tue, 29 Oct 2019 09:54:32 -0700 [thread overview]
Message-ID: <ed9f16c30a0f3852abaf0053d8c2b4a0ecd12f01.1572367897.git.liu.denton@gmail.com> (raw)
In-Reply-To: <3f6d132663cacde01df68bfe88c6ef108cf6cf74.1572337045.git.liu.denton@gmail.com>
Within diff_no_index(), we have the following:
revs->diffopt.flags.exit_with_status = 1;
...
/*
* The return code for --no-index imitates diff(1):
* 0 = no changes, 1 = changes, else error
*/
return diff_result_code(&revs->diffopt, 0);
Which means when `git diff` is run in `--no-index` mode, `--exit-code`
is implied. However, the documentation for this is missing in
git-diff.txt.
Add a note about how `--exit-code` is implied in the `--no-index`
documentation to cover this documentation blindspot.

Thanks for the review, Dscho. I guess it slipped my mind that we could
write it this way too. Oops!
