[OT] org-caldav and radicale

[OT] org-caldav and radicale

[Eric Abrahamsen]

I'm finally getting around to trying to have an Org-generated calendar
available on my Android tablet. I looked at a few caldav servers, and
settled on Radicale as looking like about the right level of
usability/configurability.

I don't think I'm doing it right, and can't find any examples online.
Can someone who's doing this (I know there are some of you) just show me
the basic configuration? Specifically, how do I create a new calendar on
the server, and how do I refer to it? My Radicale config has this:

[storage]
type = filesystem
filesystem_folder = /home/eric/apps/cal/collections

If I touch a file called "eric" in the "collections" directory, and then
access the server via HTTP (ie http://cal.myserver.com/eric), the file
is correctly served as an (empty) calendar and downloaded by my browser.

How do I get org-caldav to mesh with that? I thought this would do it:

(setq org-caldav-url "http://cal.myserver.com")
(setq org-caldav-calendar-id "eric")

But when I call `org-caldav-sync' it first collects all the headings
it's supposed to, and then gives me:

org-caldav-get-event-etag-list: Error while getting eventlist from
http://cal.myserver.com/eric/. Got status code: 207.

If I run it again, it offers to delete all the relevant Org headings.

I suspect I've just got something configured wrong, but can't think of
what. Any pointers?

Thanks!
Eric

Well I just put it on my server over http/DAV and have it 
auto-regenerate from org (happens to be in git on the same machine) 
using a script. But even if you generate locally and push, the following 
might help you:

export bash script:

# export ical via org (funnyly, the X.org-trick causes harm here)
echo ">>> exporting iCalendar..."
emacs -batch -l ~/.emacs.d/init.el -l ~/bin/ical-export-3.el --kill

echo ">>> done with export."


export elisp script:


;; export icalendar using new icalendar exporter
(require 'ox-icalendar)

; remove-if and friends
(require 'cl)

; inhibit source block execution during export
(setq org-export-babel-evaluate nil)

;; TODO check this TZ (also if to give decimal 47 (solidus) prefix)
(setq org-icalendar-timezone "Europe/Berlin")

;; while this violates iCal (missing VTIMEZONE), it is the nicest of 
options for my setup
(setq org-icalendar-date-time-format ";TZID=%Z:%Y%m%dT%H%M%S")

;; Mins alarm
(setq org-icalendar-alarm-time 15)

;; use inhertited tags for iCal categories (add TODO state?)
(setq org-icalendar-categories '(all-tags))

;; target file
(setq org-icalendar-combined-agenda-file "~/org-export/all.ics")

; create sumo "all.ics" iCal
(org-icalendar-combine-agenda-files)

; create one without external stuff; sadly tags cannot yet be used
(let (
       (org-agenda-files (remove-if (lambda (f) (string-match "external" 
f)) (org-agenda-files)))
       (org-icalendar-combined-agenda-file "~/org-export/org-native.ics")
       )
   (org-icalendar-combine-agenda-files)
   )


The last part (without external) is only relevant if you have external 
calendars represented in org that you do not neccessarily want 
re-represented in the ical. Anyway, tweak as neccessary.


HTH,

Thanks Simon!

It's true that it wouldn't be too hard just to export an ics and get it
onto the server somehow. But I'd still like to use org-caldav, as it
allows for two-way syncing, and that gets more complex. I guess I'll
just poke around in org-caldav and see exactly what it's doing, and
figure out where I'm going wrong.
