Edit 2020-04-28: this has been released in 3.3.0. I've also added a UI for this in the account setting page. The account solution makes any already created Buteo profile as described below not listed.

I'm proposing a very first implementation as a Buteo syn plugin to subscribe to an online calendar in ICS format, see this repository. The purpose of this is to subsribe to public online calendars, like public holidays. It works like a read-only calendar that is wiped-out and recreated each time the online resource changes.

There is no UI for now to subscribes to a new URL, but it can be done easily by command line. Add the following file in ~/.cache/msync/sync/:

<profile name="subscriptions" type="sync" >

  <key name="destinationtype" value="online"/>
  <key name="enabled" value="true"/>
  <key name="hidden" value="false"/>
  <key name="use_accounts" value="false"/>

  <profile type="client" name="webcal">
    <key value="http://i.cal.to/ical/76/hessen/ferien/33fea274.08627e19-76527123.ics" name="remoteCalendar"/>
    <key value="test ICS data" name="label"/>
    <key value="true" name="allowRedirect" />
  </profile>

  <schedule enabled="true" interval="1440" />
</profile>

The file should be named subscriptions.xml, or the value of the name attribute in the first <profile> tag should be the same than the filename without the .xml extension.

Restart the synchronisation daemon with systemctl --user restart msyncd.

It should create a new calendar, store the etag if any, and then redownload the data when the etag on server has changed. To trigger a manual sync, issue dbus-send --session --type=method_call --print-reply --dest=com.meego.msyncd /synchronizer com.meego.msyncd.startSync string:'subscriptions'.

To remove the subscription, use at least package 0.0.2. From command line, issue: dbus-send --session --type=method_call --print-reply --dest=com.meego.msyncd /synchronizer com.meego.msyncd.removeProfile string:'subscriptions'. This will remove the calendar from the database and all associated events. It will also delete the subscription.xml file from the msyncd directory.

If your URL is redirecting to another one, use the allowRedirect key to true, introduced in 0.0.4.

Update issues should be corrected in 0.0.5. Take notice that this is not intended for syncing calendars that often changes. Events are deleted and recreated, and due to how mkcal is handling deleted events, these events are still in the database. So the databse is growing at each sync (except if etag is provided and not changed).

This is very early stage implementation, please report bug when you find any, latest package (0.0.5).
