Term-ansicolor-hi is a project mainly written in Ruby, based on the GPL-2.0 license.
Ruby library that colors strings using ANSI escape sequences. Exactly the same as term-ansicolor (http://flori.github.com/term-ansicolor) but includes the high intensity colors.
== ANSI escape sequences in Ruby
Note:
The original author is not answering pull requests and I really needed high-intensity colors.
This necessitated me renaming the library so I could publish a new one.
All credit remains with Florian Frank.
=== Description
This library can be used to color/decolor strings using ANSI escape sequences.
=== Installation
Just type into the command line as root:
Or if you prefer using Rake, try:
Or if you want to use rubygems just type this and rubygems fetches the gem and installs it for you:

=== Examples
Additional to the two executables cdiff and decolor, the file examples/example.rb in the source/gem-distribution shows how this library can be used:
require 'term/ansicolorhi'
# Use this trick to work around namespace cluttering that
# happens if you just include Term::ANSIColorHI:
class Color
extend Term::ANSIColorHI
end
# Begin Edit (Mike Bethany)
# You don't just have to use print to get the colors.
# You can use the color attributes as standard Ruby string by adding
# them and embedding them with other strings as you normally would:
#
c = Term::ANSIColorHI
my_red_string = "#{c.red}I'm red!#{c.reset}"
my_green_string = "#{c.green}I'm green!#{c.reset}"
my_blue_string = "#{c.blue}I'm blue!#{c.reset}"
# Then you can output them using the standard Ruby 'puts' command:
puts my_red_string
puts my_green_string
puts my_blue_string
# End edit
print Color.red, Color.bold, "No Namespace cluttering:", Color.clear, "
"
print Color.green + "green" + Color.clear, "
"
print Color.on_red(Color.green("green")), "
"
print Color.yellow { Color.on_black { "yellow on_black" } }, "
"
# Or shortcut Term::ANSIColorHI by assignment:
c = Term::ANSIColorHI
print c.red, c.bold, "No Namespace cluttering (alternative):", c.clear, "
"
print c.green + "green" + c.clear, "
"
print c.on_red(c.green("green")), "
"
print c.yellow { c.on_black { "yellow on_black" } }, "
"
# Anyway, I don't define any of Term::ANSIColorHI's methods in this example
# and I want to keep it short:
include Term::ANSIColorHI

=== Version History
1.0.7 Changed ANSIColor to ANSIColorHI to avoid conflicts with apps using the Original ANSIColor class (like Cucumber) 1.0.6 Update to allow high intensity colors
