require 'term/ansicolor'
module Gherkin
module Formatter
# Defines aliases for coloured output. You don't invoke any methods from this
# module directly, but you can change the output colours by defining
# a GHERKIN_COLORS variable in your shell, very much like how you can
# tweak the familiar POSIX command ls with
# $LSCOLORS/$LS_COLORS
#
# The colours that you can change are:
#
# * undefined - defaults to yellow
# * pending - defaults to yellow
# * pending_param - defaults to yellow,bold
# * failed - defaults to red
# * failed_param - defaults to red,bold
# * passed - defaults to green
# * passed_param - defaults to green,bold
# * outline - defaults to cyan
# * outline_param - defaults to cyan,bold
# * skipped - defaults to cyan
# * skipped_param - defaults to cyan,bold
# * comment - defaults to grey
# * tag - defaults to cyan
#
# For instance, if your shell has a black background and a green font (like the
# "Homebrew" settings for OS X' Terminal.app), you may want to override passed
# steps to be white instead of green. Examples:
#
# export GHERKIN_COLORS="passed=white"
# export GHERKIN_COLORS="passed=white,bold:passed_param=white,bold,underline"
#
# (If you're on Windows, use SET instead of export).
# To see what colours and effects are available, just run this in your shell:
#
# ruby -e "require 'rubygems'; require 'term/ansicolor'; puts Term::ANSIColor.attributes"
#
# Although not listed, you can also use grey
