Listing tasks in between time windows

[feedhopper]

I would like to list items in a note called

to do.md

below certain headers like

monday

and then split everything found there into dedicated time windows like

07:00-09:00 o'clock
14:00-16:00 o'clock

I tried a lot of things starting here:

description regex matches /[024][0-8]:[0-59]/

Now this particula regex works but not this:

description regex matches /[024][9-12]:[0-59]/

---

At least, the time splitting to some extend works. Callme stupid, but I did not manage to get the header thing working.

Can someone please help me with the right way to put this specific thing into action with these specific values?

Any help is very warmly appreciated...

Not a regex wizard, but I don’t think 9-12 does what you want. Is this page helpful in explaining that regex does not really do numeric ranges and potential workarounds? Dave

Hi Dave,

thanks for your answer. Which page do you refer to?

[feedhopper]

The working regex I have from here:
https://obsidian-tasks-group.github.io/obsidian-tasks/queries/regular-expressions/#finding-times

But I am not a programmer. I am not familiar with how regex really works, so I have trouble adjusting this to the 24 hour frame I want to work in

Oops, so sorry… https://regextutorial.org/regex-for-numbers-and-ranges.php Dave

Was that getting a little more clear now?

Honestly, no, sorry, unfortunately not. I don't have time to try and interpret all the words, many of which may not have the same meaning in my visualisation that they have for you.

I'm happy to try and answer if you can give me a pictorial or text based representation of what you are after.

[feedhopper]

Haha, that's great. I appreciate that your mind is not able to wrap itself around this.

I have difficulties myself, that's why I tried visualizing it a few days ago:

In the meantime, the things you can control in tasks that might help you formulate your own solution are:

• Grouping. You can group tasks by these values: https://obsidian-tasks-group.github.io/obsidian-tasks/queries/grouping/
  • So you can group by headings. Which means that you could put headings in the files containing tasks, and then use that to group tasks together the results page
• Sorting. You can sort by these values: https://obsidian-tasks-group.github.io/obsidian-tasks/queries/sorting/

Thanks!

Option 1

If you use the headings 'Block 1', 'Block 2' etc in the files containing your tasks, and you then can include this line in a single tasks block in your Day Planner

group by heading

Option 2

If you don't want to be constrained by headings in the files containing the tasks, you can have multiple tasks searches in your days planner

# Day Planner

## Block 1

```tasks
not done
(description regex matches /09:[0-5][0-9]/) OR (description regex matches /10:[0-5][0-9]/)
```

## Block 2

```tasks
not done
(description regex matches /11:[0-5][0-9]/) OR (description regex matches /12:[0-5][0-9]/)
```

etc

I made the assumption that you didn't want tasks with 11:00 to be listed in both slots, but you can modify the search to add a 3rd clause if you really did intend them to be included in both.

@feedhopper Just wanted to make sure you saw the above ^^

[feedhopper]

description regex matches /[012][0-9]:[0-5][0-9]/

Maybe someone can explain to me what the first bracketed 012 expresses?

[claremacrae]

Have you had a chance to read this documentation:
https://obsidian-tasks-group.github.io/obsidian-tasks/queries/regular-expressions/

[claremacrae]

description regex matches /[012][0-9]:[0-5][0-9]/

It matches 5 characters:

• the first is any character 0, 1 or 2
• second in any digit 0 to 9 (inclusive)
• 3rd is :
• 4th is any character between 0 to 5 (inclusive)
• 5th is any character between 0 to 9 (inclusive)

This is useful in searching for tasks that contain a time in 24-hour clock.

[claremacrae]

So this:

07:00-09:00 o'clock

Could be found by searching for:

description regex matches /[0][789]:[0-5][0-9]/

or

description regex matches /0[789]:[0-5][0-9]/

Wow. That is SO MUCH MORE CLEAR than in the manuals I read.
Yes, I did see the tasks manual and also had a look at the regex Dave posted before. But I have great difficulties wrapping my head around such concepts. I guess my mind is wired a very different way...
