Filter todos/tasks by tags

[murchandamus]

Hey, thanks for your work on this great tool!
I’ve been using nb for a while for my notes and after recently setting myself up with a terminal emulator on my phone, have also been making more use of the todo and task feature.
I have been considering to move all todos to nb, but noticed that it doesn't currently seem possible to filter tasks with tags, i.e. to provide tags to filter the result of nb t and nb t open.

Currently (I created this example with 7.7.1, but looking over the list of commits since that release, I think this should describe the current situation):

➜  ~ nb t a "test" --tags work
Added: [175] ✔️  20231228151232.todo.md "[ ] test"
➜  ~ nb \#work
[175] ✔️  [ ] test
➜  ~ nb t open
[175] ✔️  [ ] test
…a dozen more open todos…
➜  ~ nb todos \#work
! No todos found.
➜  ~ nb t \#work  
[175] ✔️  [ ] test
…two dozen open and closed todos…
➜  ~ nb t open \#work
[175] ✔️  [ ] test
…a dozen more open todos…

So, creating a todo with the tag #work filters only this todo from the entire list of items, but the ways I tried to use a tag in combination with calling todos up, always either brings up all todos or none.

And it would be really cool, if instead:

➜  ~ nb t \#work  
[175] ✔️  [ ] test

only produced the todos that were tagged accordingly!

@murchandamus Thanks for thinking this through. I agree. The tag filtering in ls currently delegates to search --tag while todos and tasks use list, so that functionality will need to be added to list so it's available here. I'll try to look into that soon.

Awesome! Thanks for the explanation and receptive response

@murchandamus As of version 7.11.0, todos can be filtered by tag using either nb todos \#example-tag or nb todos --tags example-tag. With tasks, all tasks within items matching the tag are displayed, not just the tasks containing the tag. I'm going to experiement and might change that to only displaying matching tagged tasks in a later iteration.

Super, thank you! I only see this now, so I haven’t played around with it yet, but it would seem to me that the behavior with tags would work well for my purposes.
