Subject: [PATCH v4 40/44] builtin-am: support and auto-detect mercurial patches
Date: Sun, 28 Jun 2015 22:06:02 +0800 [thread overview]
Message-ID: <1435500366-31700-41-git-send-email-pyokagan@gmail.com> (raw)
In-Reply-To: <1435500366-31700-1-git-send-email-pyokagan@gmail.com>
Since 0cfd112 (am: preliminary support for hg patches, 2011-08-29),
git-am.sh could convert mercurial patches to an RFC2822 mail patch
suitable for parsing with git-mailinfo, and queue them in the state
directory for application.
Since 15ced75 (git-am foreign patch support: autodetect some patch
formats, 2009-05-27), git-am.sh was able to auto-detect mercurial
patches by checking if the file begins with the line:
# HG changeset patch
Re-implement the above in builtin/am.c.
