Displaying text/calendar (VCALENDAR) parts?

[Adam Sjøgren]

Does anyone have a recipe for displaying text/calendar (VCALENDAR) parts
nicely?

Reading them "raw" isn't that appealing (too many fields, don't know
what to look for...)

How would you go about displaying them "nicely"? Picking out some
fields, formatting it somehow?

Something like:

,---------------------------------------------------.
| When: ... |
| Where: ... |
| Participants: |
| * NN1 <n...@example.com> (organizer) |
| * NN2 <n...@example.com> |
| * NN3 <n...@example.com> |
| * NN4 <n...@example.com> (optional) |
| |
| [Description...] |
`---------------------------------------------------'

Perhaps?


The next step would be to be able to generate the right kinds of emails
to send back to accept/decline a meeting etc., but that's probably
another story...


Best regards,

Adam

If anyone implements this in an easy, no-twiddling-required way, I'll be
forever in your debt---since having this feature will mean I never have
to start up the monstrosity that is Microsoft Outlook. And if you implement
it in a way that integrates with org-mode, you'll be a god among men.

I can't help in writing the code, but I'll be glad to stress test
anything you've got.

Hi Adam,

I was longing for some support on appointments. I saw your mail and did
a little research and I came up with this:

http://www.gnu.org/software/libtool/manual/emacs/Importing-Diary.html

It seems that the standard diary included in emacs has this
functionality. I'll give it a shot later in the day but this is probably
where I would start.

Best Regards,
Leonidas Tsampros

Is that a standard data format? If so, you'd think someone would have
written something to display them in Emacs?

More or less, yes.

I'm using this to import such things into my org agenda:

I think it is; something like rfc2445 seems to be it.

And put it into Gnus!

Nice. Is this going to be part of Org?

Not that I know of.

vCalendar is the older format which is superceded by iCalendar IIRC.

Emacs includes lisp/calendar/icalendar.el to parse the iCalendar
formats.

It could be used to apply some special formatting by default for
calendar invitations and such. Perhaps adding some nice mime-handling
function for text/calendar parts of messages automatically.

A feature I miss most in Gnus is the lack of appointment handling. I'd
like to have some simple interface to reply to appointments, make new
appointments and perhaps poll all appointments from central server.

I was planning to take a look at icalendar.el and then make some
additions for appointment handling for gnus so I wouldn't have to deal
with groupwise client.

Hi Lars,

I took up the task and made a sample configuration snippet on how I
imagine rendering text/calendar mime parts. It's very crude but you get
the idea. There are some things missing however I'm planning to improve
it real soon adding some font locking, extra information from vcalendar
invitation.

The below snippet has been tested with both an Outlook generated meeting
request and a Google Calendar one.

My real target is to be able to response to these messages too in the
appropriate way (Accept/Reject etc).

Anyway here you go:

(add-to-list 'mm-inlined-types "text/calendar")
(add-to-list 'mm-automatic-display "text/calendar")
(add-to-list 'mm-inline-media-tests '("text/calendar" mm-inline-text-calendar identity))

(require 'icalendar)
(require 'boxquote)

(add-to-list 'mm-inlined-types "text/calendar")
(add-to-list 'mm-automatic-display "text/calendar")
(add-to-list 'mm-inline-media-tests '("text/calendar" mm-inline-text-calendar identity))

(require 'icalendar)
(require 'boxquote)

(defun mm-inline-text-calendar (handle)
(with-temp-buffer
(mm-insert-part handle)
(save-window-excursion
(setq text (lala (icalendar--read-element nil nil)))))
(boxquote-text text)
(mm-insert-inline handle "\n"))

(defun lala (temp)
(setq elems '(ORGANIZER ATTENDEE SUMMARY)
e (car (icalendar--all-events temp)))
(let (value)
(dolist (el elems)
(setq value (format (concat "%s:%s\n" value)
el
(icalendar--get-event-property e el))))
value))

I think it is more important to allow users to add them to their emacs
diary. i.e. it would be nice if Gnus can display the summary of the
invitation with button: [Accept] and [Refuse], and when it is accepted
add the event to diary.

I agree. Upon accepting an event that should be added either to an org
or diary file. That should be customizable by the user.

I've just asked Vagn J. his permission for integrating this
into Org's contrib/ directory. Then we can rework it to make
it part of Org's core.

I'll let you know about Vagn answer.

Looks good. If you finish it, and are willing to assign copyright
assignments for the FSF, we could include this in the next Gnus version.

Any news on this? If Leonidas is not able to assign the copyright, I
can reimplement his idea.

I can't recall getting a response from Leonidas, but then again, my
memory isn't all that... reliable...
