Attempting to wrap a Logging::Logger in a ActiveSupport::TaggedLogging raises an error #27
Description
Hi,
ActiveSupport::TaggedLogging is supposed to be able to wrap "any standard Logger object". However, when wrapping an instance of Logging::Logger, this does not work:
ActiveSupport::TaggedLogging.new(Logging::Logger.new(STDOUT))
=> NoMethodError: undefined method `formatter=' for #<Logging::Logger:0x007fa3f98c14d8>
This is because ActiveSupport::TaggedLogging tries to set a formatter in case it doesn't exist.
Since code that tries to wrap the Rails.logger object in a ActiveSupport::TaggedLogging instance is becoming more and more common in the rails ecosystem (cf. here in webpacker), this can be deter many users from using this otherwise good framework.
There is a formatter method already defined in Logging so maybe it could be possible to map formatter= to the MDC feature of Logging?
Also, not sure if this should be part of the logging or the logging-rails repo, it has to do with rails but the RailsCompat module is in the logging repo..
