[PATCH 0/2] multipart/alternative display and text/calendar

[Jani Nikula]

I like to have notmuch-show-all-multipart/alternative-parts nil. I'd also
like to see the text/calendar alternatives that I keep getting that have
the information that the text/plain alternative is missing (like date and
time *sigh*).

Patch 1 allows me to specify the alternative parts I want to always see
(nil and t work as before):

(setq notmuch-show-all-multipart/alternative-parts '("text/calendar"))

Patch 2 parses text/calendar as text/x-vcalendar for me so I don't have to.

BR,
Jani.

Make notmuch-show-all-multipart/alternative-parts accept a list of
multipart/alternative types to show in addition to the preferred
types. This allows the user to force display some alternative part
types while normally showing just the preferred ones.

Treat text/calendar as text/x-vcalendar. At least the following
produce text/calendar that parse as text/x-vcalendar:

PRODID:-//Google Inc//Google Calendar 70.9054//EN
PRODID:Microsoft Exchange Server 2010

I wish I had some references here, other than my own maildirs. Almost
all of the calendar invites I have are text/calendar, and all of them
parse just fine as text/x-vcalendar.

It would be convenient if this was a list of regexps.

It seems that "text/calendar" is officially sanctioned and
"text/x-vcalendar" is old and being phased out, so these should really
be the other way around (i.e. text/calendar is the 'real' function that
is called by the text/x-vcalendar variant).

This is quite messy. How about we add a general helper to "notmuch-lib.el":

(defun notmuch-string-match-list-p (regexps string)
  (loop for regexp in regexps
        if (string-match-p regexp string)
        return t))

and then write:

    (if (or (string= chosen-type inner-type)
            (equal notmuch-show-all-multipart/alternative-parts t)
            (notmuch-string-match-list-p notmuch-show-all-multipart/alternative-parts inner-type))
       ...

?

*sigh* I was so happy to make that mapconcat work. And I guess soon I'll
have to add "code by dme" in this patch too. ;)

But you're right, it will be more readable that way. v3 in a few days.

Hmm. I wrapped the regexps between ^ and $ to not match substrings. I
think that's less surprising and better than having the user add them,
and the user can still use e.g. ".*foo.*" to explicitly match a
substring.

If this is fixed in notmuch-string-match-list-p then it's not general
anymore. But does adding a mapcar to wrap the regexps here make this
messy again...? What if notmuch-string-match-list-p were just a local
specific helper for clarity?

Something like this could work...

 (defun notmuch-string-match-list-p (regexps string)
   (loop for regexp in regexps
  if (string-match-p (concat "^" regexp "$") string)
  return t))

But if you-re going to pre-anchor these regexps then it is better to be
documented clearly as the final 'regexp' works in non-standard way.

Wah, this patch (1/2) is crap, as it also seems to affect the
reply. I'll probably return to this later, after the json reply stuff is
merged or so.

David (B, not E), while 1/2 needs work, this 2/2 is independent and IMHO
could go in.
