Running task delete will go through the tasks one by one and delete them but it takes forever if there are thousands of them. What would the effect be of deleting the rows in the tasks table? I didn't try this because I see there are other tables referencing that data, but could that be a 'last resort' way of recovering?

Thanks!

Hm, that sounds like a bug in the recurrence! I've never used bare integers for due or wait - do those always parse as hours of the day?

As for recovering from this -- deleting the tasks without deleting the corresponding operations will leave your DB inconsistent, which will cause issues later. One option may be task export, filtering with a text editor, and task import?

Hi, so if you run task add foobar due:10, it will fail silently, and then when you do task list you get "'10' is not a valid date in the '' format".

So I think for some reason this error is causing the recurrence to attempt to add the task over and over again. I did try a task export but all it did was print an open bracket to the json file.

I was able to get out of this by doing task undo a number of times until task list doesn't hang.

Also, using the bare integer was just a newbie error, I did task add recur:daily due:10:00 wait:6:00 foobar and everything worked fine

[djmitche]

Hm, sounds like we have a validation issue on date/time properties, then, where we accept bare integers but then later complain about them.

I have an extended question on this and looking forward to your opinion on this.

I am trying to schedule a task for habit, which should follow the following:
1- It should schedule daily with a due date 11:59 PM
2- When the due date is over, it should not been shown. However, it should be included in not completed while analyzing burndown chart.

I have tried several methods but the problem, the task repeated with -negative due date. Since, it is for habit, when due date is gone, it should be gone. No, need to show due date with negative due date.

Could you all please share your opinion, how to accomplish this task??

thanks

Hei,
I am not sure about the second part of your requirements, however for the first one you could use the until property, see Using Dates Effectively.
So you could use a command like this

task add \
 recur:daily \
 due:23:59 \
 wait:6:00 \
 until:due \
 foobar

I just do not know how it will pop up in the burndown chart. As far as I know, deleted tasks are not shown in there.
