Some more emacs lisp for interacting with launchpad by email (specifically, with Gnus). Previously, I wrote some code which allowed for easy transfer of a bug report by e-mail to launchpad; I've since adapted that to add a Cc to the original reporter, so that they know the bug has been filed (sadly too late for any of the reports that I have actually filed; maybe this blog can serve as a heads-up...)
However, this doesn't solve the entire issue, which is painless and seamless interaction. Comments to bugs are delivered by mail, and filtered using the X-Launchpad-Bug header to an appropriate mail directory, but replies to those comments need to be cryptographically signed for those replies to be accepted by launchpad. How to do that? Initially, I hoped that there would be some group parameter or posting style which would automatically insert the mml code for signing; suspicion alighted on `gnus-message-replysign', but unfortunately the messages that launchpad sends aren't signed, even if the ones that are sent to it must be.
It would also seem that there isn't an appropriate hook for this; all the hooks I could find seem to be run too early, and attempts to call `mml-secure-message-sign-pgpmime' gave me errors about a corrupt mail buffer (because the body separator hadn't been set up yet). So, instead, I ended up piggy-backing on the code handling gnus-message-replysign anyway, by advising the relevant function as follows:
(defadvice gnus-summary-handle-replysign (after handle-launchpad-replysign activate) (when (string-match "list.*-launchpad" gnus-newsgroup-name) (mml-unsecure-message) (mml-secure-message-sign-pgpmime)))
The alert will note that this automatically signs not replies to messages from my sbcl-launchpad buffer, but from any of my list groups matching -launchpad. Is this just speculative generality, I hear you ask? No, because Alastair Bridgewater has kindly volunteered to participate in CLX development and release engineering, and his first and second acts were to set up a mailing list (hopefully permanent, this time, after clozure and metacircles abandonment) and a launchpad bugtracker. So if you've been building up scads of patches and annoyances with my clx branch (or even worse, the ancient 0.7.3 release), now might be a good time to attempt to report the annoyances and integrate the patches; particularly from those still-active projects with heavy CLX use (e.g. StumpWM, Eclipse (no not that one) and McCLIM).
