Defined in:
lib/polylog/solo_provider.rb

Overview

The purpose of the SoloProvider is to return a single instance for all logger requests. You would use this provider to supply all parts of the application with the exact same logger.

The NullLogger uses the SoloProvider to register itself under the “null” provider name.

Examples

Polylog.register_provider 'stdout', Polylog::SoloProvider.new(Logger.new(STDOUT))
Polylog.register_provider 'stderr', Polylog::SoloProvider.new(Logger.new(STDERR))
Polylog.register_provider 'file',   Polylog::SoloProvider.new(Logger.new('app.log'))

Polylog.use_provider 'stderr'
logger = Polylog.logger     # returns a STDERR logger

Polylog.use_provider 'file'
logger = Polylog.logger     # returns an 'app.log' file logger
