Logger

Extended variation of Ruby‘s standard Logger library. Mainly for compatibility purposes (with what?) 

  log = Logger.new

  log.setup_format do |severity, timestamp, progname, msg|
    Logger::SIMPLE_FORMAT % [severity, msg]
  end

When using debug level logger messages always append ‘if $DBG’ at the end. This hack is needed because Ruby does not support lazy evaluation (lisp macros).

TODO: What‘s all this about then?

setup_format(&format_proc)

Dictate the way in which this logger should format the messages it displays. This method requires a block. The block should return formatted strings given severity, timestamp, msg, progname.

Example

logger = Logger.new logger.setup_format do |severity, timestamp, msg, progname| 

  "#{progname}@#{timestamp} - #{severity}::#{msg}"

end

# File lib/lore/facets/logger.rb, line 151
  def setup_format(&format_proc)
    raise "Formating block needed" unless format_proc
    @format_proc = format_proc
  end
