GNUs open PDF attachments: how to switch to PDF-Tools?

[Tory S. Anderson]

When I receive an email (using Gnus) with a PDF attachment, attempting to open it uses DocView despite my having PDF-Tools installed and working for all PDF opening I otherwise do. But search as I might, I can't find the variable or commmand that would allow me to change the program/function that is used for the PDF attachment. How can I change this setting to specify PDF-Tools for opening attached PDFs?

I use e to open attachments with external programs (with cursor being on
the attachment in the article buffer).

PDF Tools (`pdf-view-mode') is no external program but a major mode for
viewing PDFs in Emacs similar (but much more advanced) than
`doc-view-mode'.

I've just added support for that in Gnus with this commit:

There's a thread on gnus.general about this -- lots of people are
having trouble getting Gnus to respect view-part-externally. I used to
only have trouble with PDFs, but I follow Gnus git, and now I have
trouble with most file formats. Lars identified weirdness in the
function `gnus-mime-view-part-externally', but no one's really tackled
it yet. I tried edebugging the function and following it a few times,
and it totally confused me.
