Allow adjusting the fontsize of the pulsectl default device popup

[TheEdgeOfRage]

I've recently started using the pulsectl tk popup to pick the default device and one annoying thing is that the default font size is way too small for me, so I added basic support for changing it. I'm not sure if this is a good way to implement it, let me know if not :)

Edit: I just remembered that I should probably also update the docs :sweat_smile: I'll try to get around to that later today after work

Nice addition, thank you very much! Great to read from you again!

I think eventually, the best option probably would be having this as global (module independent) parameter. What do you hink?

[TheEdgeOfRage]

Oh, I didn't know you can have global ones. That would definitely be preferred then :D

How do I define it globally?

[tobi-wan-kenobi]

Those are the parameters defined outside the modules (in config.py, i think, can't remember for sure and don't have a pc handy)

I think popup should then have access to that via a config object.

Looking at it in a bit more detail:

• If you look at bumblebee_status/core/config.py, you can see how "interval" is set on a global level, and use it via config.<accessor>(). I think that maybe this would be the best option here.
• More generally, it might make sense to always recurse to a global parameter, if no more specific one is present (i.e. use pulsein.fontsize, but if that is not found, use fontsize - what do you think?
• Generally, I think the fontsize logic should be in the popup module, not in the individual widget modules, what do you think?

If you prefer, I can put together a draft PR for those changes, as they are targeting the core quite a bit.

Sorry, I haven't had much time these days to finish this. I've removed the code from the pulsectl module and I agree with your third point that it should ideally all be in config and the popup module. The issue I'm having is that config is a Class definition, but the instance is only available in the main file. Would it make sense to have config be a singleton that can be imported from other modules?

[tobi-wan-kenobi]

An instance (the instance, actually) of Config is passed as the first parameter to init() of all modules, iirc. Does that help?

[tobi-wan-kenobi]

Looks good, thank you very much!
