Class HighLine::ColorScheme
In: lib/highline/color_scheme.rb
Parent: Object

ColorScheme objects encapsulate a named set of colors to be used in the HighLine.colors() method call. For example, by applying a ColorScheme that has a :warning color then the following could be used:

  colors("This is a warning", :warning)

A ColorScheme contains named sets of HighLine color constants.

Example: Instantiating a color scheme, applying it to HighLine,

         and using it:

  ft = HighLine::ColorScheme.new do |cs|
         cs[:headline]        = [ :bold, :yellow, :on_black ]
         cs[:horizontal_line] = [ :bold, :white ]
         cs[:even_row]        = [ :green ]
         cs[:odd_row]         = [ :magenta ]
       end

  HighLine.color_scheme = ft
  say("<%= color('Headline', :headline) %>")
  say("<%= color('-'*20, :horizontal_line) %>")
  i = true
  ("A".."D").each do |row|
     if i then
       say("<%= color('#{row}', :even_row ) %>")
     else
       say("<%= color('#{row}', :odd_row) %>")
     end
     i = !i
  end
