Subject: [PATCH v8 2/2] send-email: expose header information to git-send-email's sendemail-validate hook
Date: Wed, 18 Jan 2023 11:32:03 -0500 [thread overview]
Message-ID: <20230118163203.488652-3-michael.strawbridge@amd.com> (raw)
In-Reply-To: <20230118163203.488652-1-michael.strawbridge@amd.com>
To allow further flexibility in the Git hook, the SMTP header
information of the email which git-send-email intends to send, is now
passed as the 2nd argument to the sendemail-validate hook.
As an example, this can be useful for acting upon keywords in the
subject or specific email addresses.
As a consequence of needing all the header data, validation has been
moved later in the sequence to right before sending the emails instead
of at the beginning.

sendemail-validate
~~~~~~~~~~~~~~~~~~
-This hook is invoked by linkgit:git-send-email[1]. It takes a single parameter,
-the name of the file that holds the e-mail to be sent. Exiting with a
-non-zero status causes `git send-email` to abort before sending any
-e-mails.
+This hook is invoked by linkgit:git-send-email[1].
+
+It takes these command line arguments. They are,
+1. the name of the file which holds the contents of the email to be sent.
+2. The name of the file which holds the SMTP headers of the email.
+
+The SMTP headers are passed in the exact same way as they are passed to the
+user's Mail Transport Agent (MTA). In effect, the email given to the user's
+MTA, is the contents of $2 followed by the contents of $1.
+
+Below is an example for a few common headers. Take notice of the
+capitalization and multi-line tab structure.
+
+ From: Example <from@example.com>
+ To: to@example.com
+ Cc: cc@example.com,
+ A <author@example.com>,
+ One <one@example.com>,
+ two@example.com
+ Subject: PATCH-STRING
+
+Exiting with a non-zero status causes `git send-email` to abort
