What Hacker News says
13 sourcesSynchronize calendars and contacts (caldav, carddav)
2 points · Open discussionExchange has an API that could be used for syncronising. I always wanted to build this into vdirsyncer [1] (so that I can use khal with my work Office 365 account) but haven't found the time.
https://github.com/pimutils/vdirsyncer.
In Modern TUI calendar and task manager with customizable interfaceI feel you, but to me it was worth the effort and now I have a setup that works.
I run a calendar server[0] that is my main calendar repository. And I use vdirsyncer[1] to sync to my laptop to use khal[3]. On the Android side I sync with davx5[4].
This allows me to subscribe to webcal calendars, which outlook365 offers, and syncs them to my two main devices.
Not perfect because that means I can't edit my outlook calendar from within this system ( and a reminder why open standards and interoperability are important ), but it means that my private calendars and addressbooks are self hosted.
You are right though, that takes effort. And I want to snark at microsoft for not supporting caldav, but then I am waiting for gnome-calendar to support it as well. It doesn't seme to and that feels a bit strange to me.

Perhaps you mean vdirsyncer[1]?

In Own your calendar and contacts with OpenBSD, Baïkal, and FOSS AndroidThis is what I use for my CLI email client (aerc). I keep mail and contacts sync'd using fastmail as my backbone with a couple of crons using:
- https://github.com/pimutils/vdirsyncer
- https://isync.sourceforge.io/mbsync.html
In Ppl: The command line address bookAnother comment already mentioned Khard, which has been around a while. [0]
There's also Mates [1]. Less mature, very simple, but it's what I personally use.
I try to steer away from relying on CLI tools implemented in python or ruby: at the system level they always seem to cause dependency hell problems eventually. Mates is implemented in Rust, so it's compiled, which is primarily why I chose it.
An important related project is vdirsyncer [2]. Ppl, khard, and mates all store data in vcard format but don't talk to APIs or sync anything. Vdirsyncer can sync your vcard collection with your email provider or what have you.

In Ppl: The command line address bookLooks like vdirsyncer can sync with Google calendar and contacts: see

In Pimutils: The coreutils of personal information managementThanks for your interest. Do you maintain something yourself? Do you have some projects on your mind which could adopt such approach?
I am currently just beginning my research of the current state of things in Linux distributions with regard to the distribution (pun not intended) of bugticket time to resolution. I am doing this to get a fine grasp of actual state, and be able to articulate the additional value of such userbase-funded commitments.
I aspire to tracking my commitments up to full deployment in SDLC terms, but it seems this information is too hard to consistently get with the existing bugticket handling practices of Linux distros, so now I am going to start with measuring how much time it takes to mark the ticket "closed" or "resolved", whatever that means (seems to mean mostly "integration completed" in SDLC terms).
I sketch

some of my thoughts here, but the notes are somewhat outdated: https://github.com/userbase-funded/wiki/wiki
I have also contacted the current maintainer of one valuable but neglected project, but got no response so far. That project is vdirsyncer, it has been not actively maintained for a year and a bit until recently, but has many consumers, and I think such projects are a good fit for my idea. https://github.com/pimutils/vdirsyncer/issues/790
Vdirsyncer: Sync and Backup Tool for CalDAV and CardDAV
1 points · Open discussionI use Khard for contacts and khal for calendar.
Neither handle syncing, so I use vdirsyncer for that (you can use anything you like or just go local only).
