can i use whistlepunk in my library, without configuring it?

[mxriverlynn]

I'm replacing my current use of console.log with whistlepunk, finally... and i'm about to start putting it into my rabbus library.

i would like to use whistlepunk in rabbus without specifying a configuration for output / level / etc?

in other words, i want to be able to call logger.debug and logger.warn, etc., but i don't want to pre-configure the output location of the logging from within rabbus. i want to let the primary application instance determine where the logs should go, and what level of logs to show.

is this possible with whistlepunk, at the moment? I was looking at wascally, and i see it is configuring a level and adapter... is that really the best idea? shouldn't wascally (and other libraries) let the application process determine the adapters and level to log?

you can override logging for wascally in the config passes to it. You also have the ability to opt out of any wascally messages based on the topics you subscribe to in the host process. It should be pretty simple to have rabbus only supply logging config from the host app. I can dig up some examples if that'd help.

a few basic examples would be good - probably best to post it in the docs somewhere, for people that want to know

having banged my head against this for a day's worth of hours, i don't see how it is possible to configure the wascally / rabbus logging from outside of wascally / rabbus.

every time i call the whistlepunk function, i get a new LoggerFactory with the configuration i supplied.

wascally has to call this on it's own, and so does rabbus. so i end up with a separate LoggerFactory for each of these, neither of which can be modified by my application.

both wascally and rabbus publish to the default "log" channel on postal, so i can use the topic configuration in my app to exclude or include these libraries... but i can't change the log level for these libraries without changing the source code of the library.

am i missing something, here?

Did you consider using winston @derickbailey? We wrote a winston adaptor for a basic logger interface in Space that might be worth a look for design inspiration. The separate package now provides the implementation that can be configured in an application using the core winston API, with access to the long list of transports.
