Way to change logger name

[cquiroz]

It would be nice for me to change the name of a passed Logger instance so I can differentiate across classes.

I think a method like def withName(s: String): Logger[F] would do

WDYT?

These seems nice. Is anyone else sure how this translates to any backends other than slf4j?

Good question, I’ll try to prototype this in a PR

I feel that the canonical way of dealing with logger names would be passing a LoggerFactory instance to class constructors instead of the Logger itself. Then, a new class-related instance of Logger is supposed to be created over there that would "latch" the class name per se.

The suggested withName method could be an alternative approach of course but to me it seems like a leaky abstraction a bit, because one class can be passed with Logger from another class and therefore start emit log messages on behalf of the other one.

Yup, I think a LoggerFactory constraint is currently the best practice way to support logging. Or at least, that's what we did in http4s.
