TODO: Implement ask for Bundler::Thor::Shell::HTML

set_color(string, *colors) click to toggle source

Set color by using a string or one of the defined constants. If a third option is set to true, it also adds bold to the string. This is based on Highline implementation and it automatically appends CLEAR to the end of the returned String.

 
               # File bundler/vendor/thor/lib/thor/shell/html.rb, line 51
def set_color(string, *colors)
  if colors.all? { |color| color.is_a?(Symbol) || color.is_a?(String) }
    html_colors = colors.map { |color| lookup_color(color) }
    "<span style=\"#{html_colors.join('; ')};\">#{Bundler::Thor::Util.escape_html(string)}</span>"
  else
    color, bold = colors
    html_color = self.class.const_get(color.to_s.upcase) if color.is_a?(Symbol)
    styles = [html_color]
    styles << BOLD if bold
    "<span style=\"#{styles.join('; ')};\">#{Bundler::Thor::Util.escape_html(string)}</span>"
  end
