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 module Colors include Term::ANSIColor ALIASES = Hash.new do |h,k| if k.to_s =~ /(.*)_param/ h[$1] + ',bold' end end.merge({ 'undefined' => 'yellow', 'pending' => 'yellow', 'failed' => 'red', 'passed' => 'green', 'outline' => 'cyan', 'skipped' => 'cyan', 'comments' => 'grey', 'tag' => 'cyan' }) if ENV['GHERKIN_COLORS'] # Example: export GHERKIN_COLORS="passed=red:failed=yellow" ENV['GHERKIN_COLORS'].split(':').each do |pair| a = pair.split('=') ALIASES[a[0]] = a[1] end end ALIASES.each do |method, color| unless method =~ /.*_param/ code = <<-EOF def #{method}(string=nil, monochrome=false, &proc) return string if monochrome #{ALIASES[method].split(",").join("(") + "(string, &proc" + ")" * ALIASES[method].split(",").length} end # This resets the colour to the non-param colour def #{method}_param(string=nil, monochrome=false, &proc) return string if monochrome #{ALIASES[method+'_param'].split(",").join("(") + "(string, &proc" + ")" * ALIASES[method+'_param'].split(",").length} + #{ALIASES[method].split(",").join(' + ')} end EOF eval(code) end end def self.define_grey #:nodoc: begin gem 'genki-ruby-terminfo' require 'terminfo' case TermInfo.default_object.tigetnum("colors") when 0 raise "Your terminal doesn't support colours" when 1 ::Term::ANSIColor.coloring = false alias grey white when 2..8 alias grey white else define_real_grey end rescue Exception => e if e.class.name == 'TermInfo::TermInfoError' STDERR.puts "*** WARNING ***" STDERR.puts "You have the genki-ruby-terminfo gem installed, but you haven't set your TERM variable."
