A composable logging system built on the standard Logger library. You can add Loggability to large libraries and systems, then hook everything up later when you know where you want logs to be written, at what level of severity, and in which format. An example: # Load a bunch of libraries require 'strelka' require 'inversion' require 'treequel' require 'loggability' # Now tell everything that's using Loggability to log to an HTML # log file at INFO level Loggability.write_to( '/usr/local/www/htdocs/log.html' ) Loggability.format_as( :html ) Loggability.level = :info
