Module: Gherkin::Formatter::AnsiEscapes

Included in:: PrettyFormatter, PrettyFormatter::ColorFormat

Defined in:: lib/gherkin/formatter/ansi_escapes.rb

Overview

Defines aliases for ANSI coloured output. Default colours can be overridden by defining a GHERKIN_COLORS variable in your shell, very much like how you can tweak the familiar POSIX command ls with <a href=“mipsisrisc.com/rambling/2008/06/27/lscolorsls_colors-now-with-linux-support/”>$LSCOLORS/$LS_COLORS</a>

The colours that you can change are:

undefined: defaults to yellow
pending: defaults to yellow
pending_arg: defaults to yellow,bold
executing: defaults to grey
executing_arg: defaults to grey,bold
failed: defaults to red
failed_arg: defaults to red,bold
passed: defaults to green
passed_arg: defaults to green,bold
outline: defaults to cyan
outline_arg: defaults to cyan,bold
skipped: defaults to cyan
skipped_arg: 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_arg=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
