New blog post about calendars and calendar feeds. RSS is back, let's bring back iCalendar too!

It's so sad. With 📆 CalDAV we have a really nice open protocol for syncing events, todos and notes. The protocol, which is technically more of a file format (iCalendar) even supports quite complex reccurence rules and even things like recurring tasks.

Unfortunately, client (and server) applications usually only implement a subset of what's possible.

Know some good ones? Let me know!

Title: P1: Emacs - calendar and Buffer-menu [2024-05-01 Wed]
window. Also, I added posibility to open buffer in
splitted window or make it wide. Now Buffer-menu is
really comfortable. 😀

Beside Buffer-menu I also use tab-line-mode with grouping
by major mode and key to switch to previuous buffer. 😎

Title: P0: Emacs - calendar and Buffer-menu [2024-05-01 Wed]
1) I write tools to import files iCalendar ical file to
Emacs holidays to be able to see them in Diary and at
calendar. There is icalendar.el in Emacs already, but it
writed is very-very poorly. 😿 I sucessfully created
holiday calendar for current year.

2) I adjusted Buffer-menu to open at always at right, but
if window is already splitted just use current #dailyreport #emacs #icalendar #holidays #buffermenu

We have updated our #AI policy to disclose the collaboration between developers and AI agents.

We aim to protect maintainers and projects while also providing clarity on what is expected.

15 years on, it comes around again. The rebooted community calendar project is running into the same issues the original one did.

@rqm I switched to it years ago and display today’s+tomorrow’s events in every shell (from ~/.mkshrc) as that’s the only way I don’t miss appointments left and right.

If you use the #MirBSD implementation, which has an extra "parse for export" flag with support for time-of-day, you can have one-way conversion to #iCalendar, which you can then read-only subscribe to from e.g. smartphones, or Bloatzilla Thunderbird.

Two-way is unwise, they hve vastly different "mightyness", e.g. recurrence is handled differently, and #BSD #calendar can do offsets from Easter and so (and MirBSD’s also from Advent), and #if and #include and cpp comments, etc. (which I use heavily in my private calendar, I even have a script to pre-fill with comment headings for the next year per calendar week).

https://evolvis.org/~tg/calendars/ has my public calendars in both formats (and links for subscribing to them through Google, for those who use that). The conversion cronjob runs nightly, as it uses "today" as startpoint for recurring events.
