Constructor Details

#initialize(logger, &block) ⇒ Wrapper

Create a Logger or Rails Logger appender instance

Ruby Logger

require 'logger'
require 'semantic_logger'
ruby_logger = Logger.new(STDOUT)
SemanticLogger.add_appender(ruby_logger)
logger =  SemanticLogger['test']
logger.info('Hello World', :some => :payload)

Enhance the Rails Logger

# Add the Rails logger to the list of appenders
SemanticLogger.add_appender(Rails.logger)
Rails.logger = SemanticLogger['Rails']

# Make ActiveRecord logging include its class name in every log entry
ActiveRecord::Base.logger = SemanticLogger['ActiveRecord']

Note: Since the log level is controlled by setting the Ruby or Rails logger directly

the level is ignored for this appender
