I read a lot of mailing lists, including the voluminous public-html.
When reading mailing list mail, I often find myself wanting a
URL to the current post in the mailing list's archives.
5064 defines the
Archived-At header for
precisely this purpose, and lots of mailing list software
provide it in their mail.
Back when I used Gnus+Gmane for following technical
mailing lists, I wrote some
elisp to make
Archived-At more useful to me.
But it’s 2009 and I’ve been using Gmail almost
exclusively for several years. Unfortunately, Gmail doesn't
expose any UI around
Archived-At, nor can
without clicking through to the “Show Original”
So I’ve made a bookmarklet that, when invoked on a Gmail
“Show Original” screen, redirects your browser to
the URL in
header. I’ve put a quick demo of the bookmarklet on
Share and Enjoy!
