module Cucumber
  module Formatter
    # This module contains helper methods that are used by formatters that
    # print output to the terminal.
    #
    # FORMAT is a hash of Proc objects, keyed by step-definition types, e.g.
    # "FORMAT[:passed]".  The Proc is called for each line of the step's
    # output.
    #
    # format_step calls format_string, format_string calls format_for to obtain
    # the formatting Proc.
    #
    # Example:
    #
    # The ANSI color console formatter defines a map of step-type to output
    # color (e.g. "passed" to "green"), then builds methods named for the
    # step-types (e.g. "def passed"), which themselves wrap the corresponding
    # color-named methods provided by Term::ANSIColor (e.g. "def red").
    #
    # During output, each line is processed by passing it to the formatter Proc
    # which returns the formatted (e.g. colored) string.
