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

    # File lib/bundler/vendor/thor/lib/thor/shell/html.rb, line 70
    def ask(statement, color = nil)
      raise NotImplementedError, "Implement #ask for Bundler::Thor::Shell::HTML"
    end

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('; ')};\">#{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
