Add "Upcoming Events" feed for /community/events

Updating description with suggestions from discussion:
- Description field should not have body, should be "{date} {event_format}"
- image should be logo

Since this is a bit of a reverse of the normal use of RSS - upcoming events instead of past blog posts - what’s the best practice for ordering items? How many items should be included?

Instead of adding something new, are any event organizers able to review #1910294: Ability to filter with comparison parameters (smaller/larger than) → ?

I was going to say:

How is Drupical doing this, for them it seems to work fine

But they are aggregating info from: groups.drupal.org/events
Where as here we are talking about: https://www.drupal.org/community/events →

The fact we have two places where you can add events probably also doesn't really help with making it easy to find what you're looking for.

@drumm thanks for the feedback.

- ordering: I'd suggest that the ordering should be similar to standard, that is "closest to now first", AKA ascending by event start date
- count: :shrug:? I think most applications for this won't require a huge number, that will be handled by the standard API. I'd say "at least 15" (the old standard number of RSS items, from what I can tell), an upper limit is up to you

@BramDriesen correct. Drupical is using a number of methods based on data sources that may be phased out in the near future. We've talked with the maintainer and he has a plan to shift to the /community/events API... when he has time.

A real shame Drupical’s codebase isn’t Open Source 😇 but that’s off topic here.

@BramDriesen you can take a look at https://www.acolono.com/en/drupical#main-content and #3283490: Source code →
