I'd prefer to not add the testify dependency.

Testify allows to write a bit more compact test code.
Which improves readability.

It's a whole new library to learn. I prefer to write tests like the Go standard library does. Also, compact ≠ readable (quite the contrary in general).

calendarName = xml.Name{namespace, "calendar"}
calendarDataName = xml.Name{namespace, "calendar-data"}
calendarColorName = xml.Name{
Space: "http://apple.com/ns/ical/",

The standard way to set the color of a calendar is: https://datatracker.ietf.org/doc/html/rfc7986#section-5.9

This is a non-standard, Apple-specfic property. I'm not sure I want to support it.

I never saw this one in real life. But happy to add this as well.

Just adding my 2 cents: I have indeed also observed the proliferation of this pseudo-standard (apple.com/ns/ical) into many open-source clients (e.g. DavX5 sets it on MKCOL). On the other hand, from my experience, after initial calendar creation, this is treated as a pure client-side property by pretty much all clients (i.e. it never gets updated again), so not sure how necessary it really is...

agreed - this is for sure a pretty low feature.
Never the less if the color is stored server side it will be "synced" once opening the calendar with another client which has some benefits of recognizing calendars.

e.g. on the owncloud 10 codebase (php+sabredav) colors are the same on all clients (owncloud calendar app in web, DAVx and iOS)

Hm, actually it doesn't seem like there is any standard way to fetch a VCALENDAR for the calendar itself in CalDAV. So RFC 7986 is only useful to set the calendar color when exporting a whole calendar as .ics.

Oh well, let's just do like everybody else then…

DisplayName string `xml:"set>prop>displayname"`
Description string `xml:"set>prop>calendar-description"`
CalendarColor string `xml:"set>prop>calendar-color"`
CalemdarTimeZone string `xml:"set>prop>calendar-timezone"`

Typo: "Calendar"

Some more general notes:

  • Please try to keep 1 commit (or 1 pull request) per separate feature
  • We don't use the "feat:" commit prefix, instead we prefix commit messages by the name of the Go package involved.

@emersion @bitfehler please review again - did not yet change the color prop name ... as explained above this is the property I see in real life .... 🤷

ResourceType internal.ResourceType `xml:"set>prop>resourcetype"`
DisplayName string `xml:"set>prop>displayname"`
Description string `xml:"set>prop>calendar-description"`
CalendarColor string `xml:"set>prop>calendar-color"`

We should probably specify the http://apple.com/ns/ical/ namespace for this prop?

MaxResourceSize int64
SupportedComponentSet []string
Timezone string

This should probably be a parsed *ical.Calendar?

We should probably check that the parsed value contains exactly one VTIMEZONE component?
