+class Module
+ # = Bite-sized separation of concerns
+ #
+ # We often find ourselves with a medium-sized chunk of behavior that we'd
+ # like to extract, but only mix in to a single class.
+ #
+ # Extracting a plain old Ruby object to encapsulate it and collaborate or
+ # delegate to the original object is often a good choice, but when there's
+ # no additional state to encapsulate or we're making DSL-style declarations
+ # about the parent class, introducing new collaborators can obfuscate rather
+ # than simplify.
+ #
+ # The typical route is to just dump everything in a monolithic class, perhaps
+ # with a comment, as a least-bad alternative. Using modules in separate files
+ # means tedious sifting to get a big-picture view.
+ #
+ # = Dissatisfying ways to separate small concerns
+ #
+ # == Using comments:
+ #
+ # class Todo
+ # # Other todo implementation
+ # # ...
+ #
+ # ## Event tracking
+ # has_many :events
+ #
+ # before_create :track_creation
+ # after_destroy :track_deletion
+ #
+ # private
+ # def track_creation
+ # # ...
+ # end
+ # end
+ #
+ # == With an inline module:

+ # Noisy syntax.

+ # after_destroy :track_deletion
+ # end
+ #
+ # private
+ # def track_creation
+ # # ...
+ # end
+ # end
+ # include EventTracking
+ # end
+ #
+ # == Mix-in noise exiled to its own file:
+ #
+ # Once our chunk of behavior starts pushing the scroll-to-understand it's
+ # boundary, we give in and move it to a separate file. At this size, the
+ # overhead feels in good proportion to the size of our extraction, despite
+ # diluting our at-a-glance sense of how things really work.
+ #
+ # class Todo
+ # # Other todo implementation
+ # # ...
+ #

+ #
+ # = Introducing Module#concerning

+ # \u0026, \u003e, and \u003c. The Unicode sequences \u2028 and \u2029 are also
+ # escaped as they are treated as newline characters in some JavaScript engines.
+ # These sequences have identical meaning as the original characters inside the
+ # context of a JSON string, so assuming the input is a valid and well-formed
+ # JSON value, the output will have equivalent meaning when parsed:
#
- # json_escape('is a > 0 & a < 10?')
- # # => is a \u003E 0 \u0026 a \u003C 10?
+ # json = JSON.generate({ name: "</script><script>alert('PWNED!!!')</script>"})
+ # # => "{\"name\":\"</script><script>alert('PWNED!!!')</script>\"}"

- # Note that after this operation is performed the output is not
- # valid JSON. In particular double quotes are removed:
+ # json_escape(json)

+ # JSON.parse(json) == JSON.parse(json_escape(json))
+ # # => true
+ #
+ # The intended use case for this method is to escape JSON strings before including
+ # them inside a script tag to avoid XSS vulnerability:
+ #
+ # <script>
+ # var currentUser = <%= raw json_escape(current_user.to_json) %>;
+ # </script>
+ #
+ # It is necessary to +raw+ the result of +json_escape+, so that quotation marks
+ # don't get converted to <tt>&quot;</tt> entities. +json_escape+ doesn't
+ # automatically flag the result as HTML safe, since the raw value is unsafe to
+ # use inside HTML attributes.
+ #
+ # If you need to output JSON elsewhere in your HTML, you can just do something
+ # like this, as any unsafe characters (including quotation marks) will be
+ # automatically escaped for you:
+ #
+ # <div data-user-info="<%= current_user.to_json %>">...</div>
+ #
+ # WARNING: this helper only works with valid JSON. Using this on non-JSON values
+ # will open up serious XSS vulnerabilities. For example, if you replace the
+ # +current_user.to_json+ in the example above with user input instead, the browser
+ # will happily eval() that string as JavaScript.
+ #
+ # The escaping performed in this method is identical to those performed in the
+ # Active Support JSON encoder when +ActiveSupport.escape_html_entities_in_json+ is
+ # set to true. Because this transformation is idempotent, this helper can be
+ # applied even if +ActiveSupport.escape_html_entities_in_json+ is already true.
+ #
+ # Therefore, when you are unsure if +ActiveSupport.escape_html_entities_in_json+
+ # is enabled, or if you are unsure where your JSON string originated from, it
+ # is recommended that you always apply this helper (other libraries, such as the
+ # JSON gem, do not provide this kind of protection by default; also some gems
+ # might override +to_json+ to bypass Active Support's encoder).
