Single address line from addr:* tags

I would like to show OSM POIs like shops on a map, and display their tag details when clicking on a POI. I would like to remove the addr:* address tags from the details, and instead display them as “full address” on one line.

This would turn e.g.

addr:street       5th Avenue
addr:housenumber  390
addr:unit         411
addr:city         New York
addr:postcode     10018
addr:state        NY

into

390, 5th Avenue, Unit 411, New York, NY, 10018

I’m fully aware that

a) Addressing systems around the world are different and complicated: Some places use blocks or suburbs instead of streets, you need unit or apartment numbers, addresses can be multilingual, and so on.
b) Conventions how to order address parts differ locally, e.g. putting the housenumber before or after the street, or putting the postcode before or after the city.
c) Address information in OSM can be incomplete, addresses for POIs would need to be taken from a surrounding building, etc.

Is there some description of rules how to put the address parts together? Maybe different rules per region?

Alternatively, is there a universal rule that could be applied and results in addresses that are mostly understood worldwide? Something like “Use addr:* in this order: housenumber, street, block, …; omit any missing tag; comma-separate them”

Is there even some code or library which implements something like this?
