From 8a3d2c99bff60cb775ebc42516c0c3912d54ba3d Mon Sep 17 00:00:00 2001 From: Calvin Morrison Date: Sat, 22 Aug 2026 13:16:49 -0400 Subject: pim: personal information management, starting with a calendar A calendar as a file tree, and tools that only know the tree: events/date/yyyy/mm/dd/hhmm-summary as lived events/uuid// as stored ctl query alarm changed lib/cal owns all of that. A backend supplies events and, where its protocol allows, takes changes back -- six methods. cmd/icalfs is the first: it reads .ics files from a directory and nothing else, because fetching is rc/fetch's job and hget already exists. That keeps net/http out of the binary and makes a subscribed calendar and a local one the same thing. The tools are rc on purpose. If the tree needs a compiled program to be useful, the tree is the wrong shape. Three things were added to the tree because the rc port needed them: a path from an occurrence to its event, epoch seconds beside RFC3339, and a numeric slot for all-day events so test(1) can compare it. ctl reports caps, so a tool can say "read only" instead of trying and failing. A published .ics is read only: nowhere to PUT, and no METHOD:REQUEST to reply to. CalDAV would be read write rsvp schedule, and that is the next backend.
