#
# This extension provides some of the helper methods that existed in Haml 5
# but were removed in Haml 6. To use this in your app, just +register+ it:
#
# require 'sinatra/base'
# require 'sinatra/haml_helpers'
#
# class Application < Sinatra::Base
# helpers Sinatra::HamlHelpers
#
# # now you can use the helpers in your views
# get '/' do
# haml_code = <<~HAML
# %p
# != surround "(", ")" do
# %a{ href: "https://example.org/" } example.org
# HAML
# haml haml_code
# end
# end
#
