Add multiple pause levels

[matejdro]

This fixes #865, specifically by introducing multiple pause levels (as outlined in #865 (comment)).

Instead of pause being a toggle, it is now a number and notification rules can set override_pause_level which determines maximum pause level at which the notification is displayed.

Old is-paused and set-paused commands are deprecated, but they still function to maintain backwards compatibility (set-paused true sets paused level to 100, which is an arbitrary number, we could pick any other if desired).

PR is not finished yet, I still need to update tests, documentation, scripts etc. but I only edited the core for now to get feedback on my approach. Does this look like something we would want in dunst?

Your suggestion for adding a pause level seems like a good approach. I would be careful with adding too many pause levels, as it could make it overwhelming for people. I'd suggest adding a maximum of 10 pause levels, since I cannot think of a situation that requires more pause levels. The limit could always be raised later.

[fwsmit]

Your approach is good and the implementation seems mostly good. Could take a look at the build errors, my comments and the documentation?

[matejdro]

Thanks for the review. Added several commits which should address things.

Hi there!
Just wanted drop by and thank you both for your work on this feature! My search engine led me here when searching how to mute/pause certain notifications only.

I'm runing dunst compiled from this branch, with two simple set-pause-level schedules using systemd user timers and so far it's working great.

If I could make a small suggestion, from the example dunstrc config it was not immediately clear to me that override_pause_level can (and probably should?) go inside rules. Perhaps it might be worth adding it to the list of things that can be overridden in the default config file. The new option is also not present in the man page.

Thanks again for your work on this! ❤️

Thanks for your improvements! The code looks good, but there are a few small documentation and naming improvements needed before this can be merged. Could you add an entry for override_pause_level in the man page as well?

Thank you for this new feature. I will merge this as soon as the tests pass

[liskin]

Wow, thanks a lot for implementing this! I wanted this for a long time, just never managed to find the time to do it myself. Tested it now, seems to work well, just needs a little fix for a bashism in dunstctl: #1230

[igorline]

Cannot get this to work properly

have this in my dunstrc now

[Spotify]
    appname = Spotify
    background = "#FF0000"
    override_pause_level = 30

when I try to set pause level to 100 messages still go through with expected red background

dunstctl set-pause-level 100

[matejdro]

Huh. If you remove override pause level, do messages still go through?

[igorline]

yeah, tried various combinations and still get notifications bypassing

[matejdro]

Which version do you have? This was just released in Dunst v10.0.

[igorline]

I installed it from master branch

[matejdro]

Are you setting override pause level to a higher value somewhere else (default configuration)?

I'm actually not sure what would be a good way to debug this. Maybe we should have added some more LOG_D statements for this?
