Subject: [PATCH v4 16/44] builtin-am: exit with user friendly message on failure
Date: Sun, 28 Jun 2015 22:05:38 +0800 [thread overview]
Message-ID: <1435500366-31700-17-git-send-email-pyokagan@gmail.com> (raw)
In-Reply-To: <1435500366-31700-1-git-send-email-pyokagan@gmail.com>
Since ced9456 (Give the user a hint for how to continue in the case that
git-am fails because it requires user intervention, 2006-05-02), git-am
prints additional information on how the user can re-invoke git-am to
resume patch application after resolving the failure. Re-implement this
through the die_user_resolve() function.
Since cc12005 (Make git rebase interactive help match documentation.,
2006-05-13), git-am supports the --resolvemsg option which is used by
git-rebase to override the message printed out when git-am fails.
Re-implement this option.
