Better use color names defined in

ruby-term-ansicolor - Ruby library that colors strings using ANSI escape sequences

Example:

require 'term/ansicolor'

This need gem install term/ansicolor, so I use the easy way.

If need I will add that.

Thanks, Xueliang

# Use this trick to work around namespace cluttering that # happens if you just include Term::ANSIColor:

class Color extend Term::ANSIColor end

print Color.red, Color.bold, "No Namespace cluttering:", Color.clear, "\n" print Color.green + "green" + Color.clear, "\n" print Color.on_red(Color.green("green")), "\n" print Color.yellow { Color.on_black { "yellow on_black" } }, "\n\n"

# Or shortcut Term::ANSIColor by assignment: c = Term::ANSIColor

print c.red, c.bold, "No Namespace cluttering (alternative):", c.clear, "\n" print c.green + "green" + c.clear, "\n" print c.on_red(c.green("green")), "\n" print c.yellow { c.on_black { "yellow on_black" } }, "\n\n"

Thanks, Fengguang
