ANSI

DESCRIPTION

Use ANSI codes in printed output, including colors and controlling the cursor, clearing the line, and clearing the screen.

INSTALLATION

as a gem:

  sudo gem install ssoroka-ansi

as a plugin:

  script/plugin install git://github.com/ssoroka/ansi.git

USAGE

require ‘ansi’ # if not installed as a plugin.

1) Simply control the cursor:

  >> puts "HELLO" + ANSI.right(30) + "THERE!"
  HELLO                              THERE!

2) use colors:

  >> puts ANSI.color(:red) { "hello there" }
  >> puts ANSI.color(:green) + "Everything is green now" + ANSI.no_color

3) loops:

  printf ANSI.clear_screen
  puts "Processing users..."
  max = User.count
  User.all.each_with_index {|user, index|
    user.update_something!
    printf ANSI.left(50) + "Processed #{index}/#{max} users..."
  }
  puts " done!"
