This looks like a great start!
Thanks @sunkup for your work on this 👍

[raimund-schluessler]

@sunkup I rebased to current master.

[arunas-smala]

Any plans to finish it? Any help needed?

Please, feel free. I don't really get to work on this more any time soon 👍

[bobiko]

What is the status of ? from what I see, it's stuck on a synchronization problem

[jancborchardt]

@jancborchardt Do you think the Nextcloud Groupware or Tasks teams could provide a helping hand to get this over the finish line? It's one of the oldest (from Nextcloud v9) and as far as I can see, it is the most requested feature in all of nextcloud by a significant margin (379 👍) As a longtime user of Nextcloud (and tasks), I've taken a few shots at implementing this myself, but haven't gotten anywhere as close as this draft PR.

@meichthys is there some list of what’s missing? cc @ChristophWurst @AndyScherzinger possibly for planning.

[meichthys]

@jancborchardt Thanks for reaching out!
Over the past few months I've lost track of the most recent progress on this, so I don't have a list of what's missing, but perhaps @sunkup could shed some light?

[sunkup]

I will look into it one of the coming days and create an overview of the current state.

[sunkup]

Here's a list of what is (not) working.

Mind you this was an experiment for me. The code is not pretty and needs refactoring from someone more experienced. While I learned a lot about vue and nextcloud apps, I realise, I don't want to work on this anymore. I hope @ChristophWurst can make something of it. If not, then maybe just use it as a template and start over from scratch. 👍

I am happy this feature gets some attention now. Looking forward to use it :)

---

• show recurring tasks with "repeat" checkbox icon (works)
• on marking as complete (Does not seem to work anymore, but did work, so probably just broken)
  • if UNTIL is not reached:
    • update the task start date, to the next recurring date (even if that one still lies in the past too)
    • clear the due date, if it lies before the next recurrence date
    • do not mark as complete
  • if UNTIL was reached: handle the task like a non-recurring; mark as complete
• on marking as cancelled (works)
  • cancel the whole recurring todo - ie "all days"
• recurrence setting in side menu (similar to the calendar app)
  • display current recurrence state (works)
  • Delete recurrence (works)
  • editing:
    • never
    • daily (works, but needs a lot of refactoring)
      • + interval
    • weekly
    • monthly
    • yearly
  • localised translations

This forum post is also about this issue, just wanted to link it here for reference :)

And in the post, the Android app tasks.org is mentioned, which supports recurrent tasks. I use it myself, and this way recurrent tasks can be synced via davx to Nextcloud. They are not displayed correctly, though, obviously :)

Probably, you already know about this, but if not, maybe knowing how tasks.org handles recurrent tasks and syncing to davx, helps during development :)

Thanks 🙂

Be careful not to mark a recurring task as complete via the Nextcloud web interface. The task recurrence will be corrupted.

This has already been implemented for the Nexcloud Calendar App. Maybe someone from the Nextcloud GmbH who was able to implement this on the Calendar App could also take a look at the Tasks App?

[ChristophWurst]

@Felitendo we (Nextcloud GmbH) are not working on this right now. The people who implemented recurrence for Calendar do not work at Nextcloud GmbH either. But the good news is that Calendar code is available to all of us, which means that there is limitation/disadvantage on who can work on repeating tasks.

[Felitendo]

@Coyote21 just use tasks.org, it has the reoccurring tasks feature and you can directly connect it to your Nextcloud via either CalDav or DAVx5

[Coyote21]

@Felitendo Yeah, thanks for the suggestion. I've decided it's something I'm going to try, but I'm reluctant/sceptical because my usual workflow involves organising my todos on the desktop when I'm at home (or in the office). I only use the Android app while I'm out and about, as reminders of where I need to go and what I need to do when I get there.

Almost all of the recurring tasks I need in my todo list are performed either at home or at the office, therefore are "checked off" using the desktop interface.

But as I said, I'm going to try experimenting with running everything from the Android app (tasks.org) as you suggested, or at least manage all the recurring tasks through tasks.org.

[meichthys]

@Coyote21, perhaps you saw this already, but take note of #2318 (comment)

I learned the hard way and don't want anyone else to have to deal with it. (Marking recurring tasks on Nextcloud currently will destroy the recurrence of the task, and at worst can corrupt the task from being viewed at all.

Tasks.org does indeed work great with the nextcloud tasks caldav backend btw.

How can we support to get this PR merged?
