Overview

Log decorator that adds ANSI colors to messages by severity:

require 'loog' require 'loog/colorful' log = Loog::Colorful.new(Loog::VERBOSE) log.debug('This will be dark gray') log.error('This will be red')

Debug messages are printed in dark gray, warnings in orange, and error messages in red. Info messages pass through unchanged.
