col: high-level console color formatting for Ruby

If you want a dash of color in your Ruby console program, use
Term::ANSIColor.
If your color formatting requirements are more complicated, use Col.
Col provides as much convenience as possible without modifying builtin
classes.

=== SYNOPSIS

require 'col'

puts Col("Hello world!").red.bold
puts Col("Hello world!").rb
puts Col("Hello world!").fmt [:red, :bold]
puts Col("Hello world!").fmt :rb

puts Col("Hello ", "world!").fmt :red, :green
puts Col("Hello ", "world!").fmt "r,g"

puts Col("Hello ", "world!").fmt [:red, :bold], [:green, :bold]
puts Col("Hello ", "world!").fmt "rb,gb"

puts Col("Hello ", "world!").fmt [:bold], [:cyan, :italic,

:on_white]
puts Col("Hello ", “world!”).fmt “_b,ciow”

puts Col("Hello ", "world!").fmt [:blue, :on_yellow], [:on_green]
puts Col("Hello ", "world!").fmt "b_oy,__og"

puts Col.inline( "Hello ", :red, "world!", :blue )

puts Col.inline(
  "Hello ",   [:red, :bold, :on_white],
  "world!",   :b_oy
)

Love the idea. Where do I find “tap”

C:/Ruby/lib/ruby/gems/1.8/gems/col-1.0.1/lib/col.rb:101:in result': undefined methodtap’ for “”:String (NoMethodError)
from C:/Ruby/lib/ruby/gems/1.8/gems/col-1.0.1/lib/col.rb:54:in
fmt' from C:/Ruby/lib/ruby/gems/1.8/gems/col-1.0.1/lib/col.rb:71:inmethod_missing’

101 String.new.tap { |str|
102 @strings.zip(@format_spec).each do |string, spec|
103 d = decorated_string(string, spec)
104 str << d
105 end
106 }

Ah… Object#tap is a Ruby 1.9 feature that doesn’t exist in 1.8.
(Actually, it probably exists in 1.8.7, but not 1.8.6 or earlier.) So
I guess Col doesn’t work in 1.8 :frowning:

It’s easily defined:
class Object
def tap
yield self
self
end
end

Thanks for the report. I’ll do some proper 1.8 testing and try to
make it work, removing any 1.9-specific code. Look for a 1.0.2
release sometime soon.

Col v1.0.2 has been released. It is compatible with Ruby 1.8.6+. I
haven’t tested any earlier versions.
