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 lib/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("; ")};\">#{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("; ")};\">#{string}</span>"
      end
    end
