From 1326ec09ee369b152a6c9bed5fe42c2d80180d01 Mon Sep 17 00:00:00 2001 From: Austin Clements Date: Thu, 20 Feb 2014 14:16:34 -0500 Subject: [PATCH] emacs: Build forwarded message buffer more directly Previously, we used `message-forward' to build forwarded messages, but this function is simply too high-level to be a good fit for some of what we do. First, since `message-forward' builds a full forward message buffer given the message to forward, we have to duplicate much of the logic in `notmuch-mua-mail' to patch the notmuch-y things into the built buffer. Second, `message-forward' constructs the From header from user-full-name and user-mail-address. As a result, if we prompt the user for an identity, we have to parse it into name and address components, just to have it put back together by `message-forward'. This process is not entirely loss-less because `mail-extract-address-components' does a lot of canonicalization (since it's intended for displaying addresses, not for parsing them). To fix these problems, don't use `message-forward' at all. `message-forward' itself is basically just a call to `message-mail' and `message-forward-make-body'. Do this ourselves, but call `notmuch-mua-mail' instead of `message-mail' so we can directly build a notmuch-y message and control the From header. This also fixes a bug that was a direct consequence of our use of `mail-extract-address-components': if the user chose an identity that had no name part (or the name part matched the mailbox), we would bind user-full-name to nil, which would cause an exception in the bowels of message-mode because user-full-name is expected to always be a string (even if it's just ""). --- emacs/notmuch-mua.el | 33 +++++++++++---------------------- 1 file changed, 11 insertions(+), 22 deletions(-) diff --git a/emacs/notmuch-mua.el b/emacs/notmuch-mua.el index 481abd7c..f2df770e 100644 --- a/emacs/notmuch-mua.el +++ b/emacs/notmuch-mua.el @@ -231,21 +231,6 @@ list."
