Hi,

Sacha asked me to document my setup, hope it's useful to you. I'd like 
to say thanks to Ulf Jasper for his help .

You will need

- Ulf Jasper's icalendar.el (http://de.geocities.com/ulf_jasper/emacs.html)
- phpicalendar on a webserver for publishing 
(http://sourceforge.net/projects/phpicalendar/)
- (optional) sitecopy for automatically pushing files via ftp to a 
webserver (http://www.lyra.org/sitecopy/)

Firstly add this to the end of your emacs diary

<example>
   # Local Variables:
   # after-save-hook: (crl/diary-export)
   # End:
</example>

This causes the function crl/diary-export to be called on save (as
there is, as far as I know, no diary-after-save-hook). Thanks to Ulf
Jasper for this tip.

Then something like this should be added to your .emacs :

<example>
(defun crl/diary-export ()
  (save-excursion
    (set-buffer (find-file-noselect "~/calendar/diary.ics" t))
    (erase-buffer)
    (icalendar-export-file "~/diary" "~/calendar/diary.ics")
    (when desktop-p
      (shell-command "/usr/local/bin/sitecopy --update diary")
      )
    )
  )
</example>

This snippet publishes the diary to the folder ~/calendar/diary.ics as
an icalendar file, and uses sitecopy to push the file to the
webserver. At the moment the save-excursion doesn't seem to work on my
emacs. Any suggestions appreciated !

On the server, or your local machine if you have apache/php
etc. installed, use phpicalendar to publish the icalendar file as a
webpage. This also generates an RSS feed. You will need to set up
sitecopy (or scp for example) to put the diary.ics file in the
phpicalendar "calendars" directory.

You end up with something that looks like this (check out the link to
RSS feeds) : http://acm.cs.uic.edu/calendar/ical/month.php


Kind regards,
