# Middleman provides an extension API which allows you to hook into the
|
|
# lifecycle of a page request, or static build, and manipulate the output.
|
|
# Internal to Middleman, these extensions are called "features," but we use
|
|
# the exact same API as is made available to the public.
|
|
#
|
|
# A Middleman extension looks like this:
|
|
#
|
|
# module MyExtension
|
|
# class << self
|
|
# def registered(app)
|
|
# # My Code
|
|
# end
|
|
# end
|
|
# end
|
|
#
|
|
# In your `config.rb`, you must load your extension (if it is not defined in
|
|
# that file) and call `activate`.
|
|
#
|
|
# require "my_extension"
|
|
# activate MyExtension
|
|
#
|
|
# This will call the `registered` method in your extension and provide you
|
|
# with the `app` parameter which is a Middleman::Server context. From here
|
|
# you can choose to respond to requests for certain paths or simply attach
|
|
# Rack middleware to the stack.
|
|
#
|
|
# The built-in features cover a wide range of functions. Some provide helper
|
|
# methods to use in your views. Some modify the output on-the-fly. And some
|
|
# apply computationally-intensive changes to your final build files.
|
|
