Would it be possible to sync calendar color?

[cwchristerw]

I'm looking for solution to get color directly from X-APPLE-CALENDAR-COLOR. Currently it doesn't work for my own calendar, I'm not sure if its implemented or not.

[rfc2822]

Is there some standard or definition of X-APPLE-CALENDAR-COLOR? Or at least some documentation on how it is used?

[cwchristerw]

Nextcloud (using SabreDav) has its value as HEX like #ffffff.
https://github.com/sabre-io/dav/blob/c1afdc77a95efea6ee40c03c45f57c3c0c80ec22/lib/CalDAV/ICSExportPlugin.php#L299

Here few resources that also reference X-APPLE-CALENDAR-COLOR to be HEX color with #:

• https://github.com/apple/ccs-calendarserver/search?q=X-APPLE-CALENDAR-COLOR&type=code
• Option override PRODID at import time ? ics-py/ics-py#278
• Deserialization fails on X-APPLE-STRUCTURED-LOCATION rianjs/ical.net#348
• Events created on Android can't be moved using Apple Calendar. ORGANIZER and ATTENDEE fields are wrong! gggard/AndroidCaldavSyncAdapater#143
• https://github.com/sabre-io/vobject/blob/d8a0a9ae215a8acfb51afc29101c7344670b9c83/tests/VObject/EmClientTest.php
• https://github.com/sabre-io/dav/blob/c1afdc77a95efea6ee40c03c45f57c3c0c80ec22/tests/Sabre/CalDAV/ICSExportPluginTest.php

Here few resources that also reference X-APPLE-CALENDAR-COLOR can be empty:

• iCalendar export plugin returns empty result when using start or end filters sabre-io/dav#1148

X-APPLE-CALENDAR-COLOR can be HEX Color (like #ffffff and #FFFFFF) or empty

Yes, thank you.
I tested it.
Here comes the result:
The COLOR value seems to be ignored, it's always using the X-APPLE-CALENDAR-COLOR hex value.
Additionally, the list of 'Abbonierte Kalender' is always empty and the slider of 'Zugangsdaten benötigt' is resetting itself to off.... Why? 3 days later: problem solved, don't know why.

[rfc2822]

Can you provide that iCalendar? Which COLOR value does it have? COLOR is expected to be a CSS3 color name, X-APPLE-CALENDAR-COLOR is a hex value.

[derflasher]

Yes. May I send the URL to your email inbox as I requested the APK?

[rfc2822]

Yes of course

[derflasher]

You've got mail!

[rfc2822]

See #31

[rfc2822]

@cwchristerw This has been implemented in the latest dev version. Would you like to test? Where did you download ICSx⁵ from?

[derflasher]

Sure! From F-Droid

[rfc2822]

I can send you an APK but you will have to uninstall the F-Droid version first (they use their own signing key). Where shall I send the APK too?

[derflasher]

No problem. You may send me via direct message or post in this thread.

[rfc2822]

How can I send a direct message? I don't want the APK or its link to be public.

Edit: There's an email address at the top of the @bitfireAT page. You could send an email there and then I can send the APK back.

[derflasher]

E-Mail sent. Thanks!

[cwchristerw]

@rfc2822 Thanks for implementing this so quickly.
