# frozen_string_literal: true
require "active_support/concern"
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 < ApplicationRecord
# # Other todo implementation
# # ...
#
# ## Event tracking
# has_many :events
#
# before_create :track_creation
#
# private
# def track_creation
# # ...
# end
# end
#
# == With an inline module:
#
# Noisy syntax.
#
# class Todo < ApplicationRecord
# # Other todo implementation
# # ...
#
# module EventTracking
# extend ActiveSupport::Concern
#
# included do
# has_many :events
# before_create :track_creation
# 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
# boundary, we give in and move it to a separate file. At this size, the
# increased overhead can be a reasonable tradeoff even if it reduces our
# at-a-glance perception of how things work.
#
# class Todo < ApplicationRecord
# # Other todo implementation
# # ...
#
# include TodoEventTracking
# end
#
# = Introducing Module#concerning
#
# By quieting the mix-in noise, we arrive at a natural, low-ceremony way to
# separate bite-sized concerns.
#
# class Todo < ApplicationRecord
# # Other todo implementation
# # ...
#
# concerning :EventTracking do
# included do
# has_many :events
# before_create :track_creation
# end
#
# private
# def track_creation
# # ...
# end
# end
# end
#
# Todo.ancestors
# # => [Todo, Todo::EventTracking, ApplicationRecord, Object]
#
# This small step has some wonderful ripple effects. We can
# * grok the behavior of our class in one glance,
# * clean up monolithic junk-drawer classes by separating their concerns, and
# * stop leaning on protected/private for crude "this is internal stuff" modularity.
#
# === Prepending concerning
#
# <tt>concerning</tt> supports a <tt>prepend: true</tt> argument which will <tt>prepend</tt> the
# concern instead of using <tt>include</tt> for it.
module Concerning
# Define a new concern and mix it in.
def concerning(topic, prepend: false, &block)
method = prepend ? :prepend : :include
__send__(method, concern(topic, &block))

# ...

# It creates and returns an instance of the ActiveSupport::Multibyte::Chars class which

# object. Interoperability problems can be resolved easily with a +to_s+ call.

"Contribution" shall mean any work of authorship, including
the original version of the Work and any modifications or additions
to that Work or Derivative Works thereof, that is intentionally
submitted to Licensor for inclusion in the Work by the copyright owner

worldwide, non-exclusive, no-charge, royalty-free, irrevocable
copyright license to reproduce, prepare Derivative Works of,
publicly display, publicly perform, sublicense, and distribute the
Work and such Derivative Works in Source or Object form.
3. Grant of Patent License. Subject to the terms and conditions of
this License, each Contributor hereby grants to You a perpetual,
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
(except as stated in this section) patent license to make, have made,
use, offer to sell, sell, import, and otherwise transfer the Work,
where such license applies only to those patent claims licensable
by such Contributor that are necessarily infringed by their
Contribution(s) alone or by combination of their Contribution(s)
with the Work to which such Contribution(s) was submitted. If You
institute patent litigation against any entity (including a
cross-claim or counterclaim in a lawsuit) alleging that the Work
or a Contribution incorporated within the Work constitutes direct
or contributory patent infringement, then any patent licenses
granted to You under this License for that Work shall terminate
as of the date such litigation is filed.
4. Redistribution. You may reproduce and distribute copies of the
Work or Derivative Works thereof in any medium, with or without
modifications, and in Source or Object form, provided that You
meet the following conditions:
(a) You must give any other recipients of the Work or
Derivative Works a copy of this License; and
(b) You must cause any modified files to carry prominent notices
stating that You changed the files; and
(c) You must retain, in the Source form of any Derivative Works
that You distribute, all copyright, patent, trademark, and
attribution notices from the Source form of the Work,
excluding those notices that do not pertain to any part of
the Derivative Works; and
(d) If the Work includes a "NOTICE" text file as part of its
distribution, then any Derivative Works that You distribute must
include a readable copy of the attribution notices contained
within such NOTICE file, excluding those notices that do not
pertain to any part of the Derivative Works, in at least one
of the following places: within a NOTICE text file distributed
as part of the Derivative Works; within the Source form or
documentation, if provided along with the Derivative Works; or,
within a display generated by the Derivative Works, if and
wherever such third-party notices normally appear. The contents
of the NOTICE file are for informational purposes only and
do not modify the License. You may add Your own attribution
notices within Derivative Works that You distribute, alongside
or as an addendum to the NOTICE text from the Work, provided
that such additional attribution notices cannot be construed
as modifying the License.
You may add Your own copyright statement to Your modifications and
may provide additional or different license terms and conditions
for use, reproduction, or distribution of Your modifications, or
for any such Derivative Works as a whole, provided Your use,
reproduction, and distribution of the Work otherwise complies with
the conditions stated in this License.
5. Submission of Contributions. Unless You explicitly state otherwise,
any Contribution intentionally submitted for inclusion in the Work
by You to the Licensor shall be under the terms and conditions of
this License, without any additional terms or conditions.
Notwithstanding the above, nothing herein shall supersede or modify
the terms of any separate license agreement you may have executed
with Licensor regarding such Contributions.
6. Trademarks. This License does not grant permission to use the trade
names, trademarks, service marks, or product names of the Licensor,
except as required for reasonable and customary use in describing the
origin of the Work and reproducing the content of the NOTICE file.
7. Disclaimer of Warranty. Unless required by applicable law or
agreed to in writing, Licensor provides the Work (and each
Contributor provides its Contributions) on an "AS IS" BASIS,
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
implied, including, without limitation, any warranties or conditions
of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
PARTICULAR PURPOSE. You are solely responsible for determining the
appropriateness of using or redistributing the Work and assume any
risks associated with Your exercise of permissions under this License.
8. Limitation of Liability. In no event and under no legal theory,
whether in tort (including negligence), contract, or otherwise,
unless required by applicable law (such as deliberate and grossly
negligent acts) or agreed to in writing, shall any Contributor be
liable to You for damages, including any direct, indirect, special,
incidental, or consequential damages of any character arising as a
result of this License or out of the use or inability to use the
Work (including but not limited to damages for loss of goodwill,
work stoppage, computer failure or malfunction, or any and all
other commercial damages or losses), even if such Contributor
has been advised of the possibility of such damages.
9. Accepting Warranty or Additional Liability. While redistributing
the Work or Derivative Works thereof, You may choose to offer,
and charge a fee for, acceptance of support, warranty, indemnity,
or other liability obligations and/or rights consistent with this
License. However, in accepting such obligations, You may act only
on Your own behalf and on Your sole responsibility, not on behalf
of any other Contributor, and only if You agree to indemnify,
defend, and hold each Contributor harmless for any liability
incurred by, or claims asserted against, such Contributor by reason
of your accepting any such warranty or additional liability.

# Rack::Builder provides a domain-specific language (DSL) to construct Rack
# applications. It is primarily used to parse +config.ru+ files which
# instantiate several middleware and a final application which are hosted
# by a Rack-compatible web server.
#
# Example:
#
# app = Rack::Builder.new do
# use Rack::CommonLogger
# map "/ok" do
# run lambda { |env| [200, {'content-type' => 'text/plain'}, ['OK']] }
# end
# end
#
# run app
#
# Or
#
# app = Rack::Builder.app do
# use Rack::CommonLogger
# run lambda { |env| [200, {'content-type' => 'text/plain'}, ['OK']] }
# end
#
# run app
#
# +use+ adds middleware to the stack, +run+ dispatches to an application.
# You can use +map+ to construct a Rack::URLMap in a convenient way.

# If the config file ends in +.ru+, it is treated as a

#
# If the config file does not end in +.ru+, it is
# required and Rack will use the basename of the file
# to guess which constant will be the Rack application to run.

#
# Rack::Builder.parse_file('app.rb')
# # requires app.rb, which can be anywhere in Ruby's

# This middleware enables content encoding of http responses,
# usually for purposes of compression.
#
# Currently supported encodings:
#
# * gzip
# * identity (no transformation)
#
# This middleware automatically detects when encoding is supported
# and allowed. For example no encoding is made when a cache
# directive of 'no-transform' is present, when the response status
# code is one that doesn't allow an entity body, or when the body
# is empty.
#
# Note that despite the name, Deflater does not support the +deflate+
# encoding.
class Deflater
# Creates Rack::Deflater middleware. Options:
#
# :if :: a lambda enabling / disabling deflation based on returned boolean value
# (e.g <tt>use Rack::Deflater, :if => lambda { |*, body| sum=0; body.each { |i| sum += i.length }; sum > 512 }</tt>).
# However, be aware that calling `body.each` inside the block will break cases where `body.each` is not idempotent,
# such as when it is an +IO+ instance.
# :include :: a list of content types that should be compressed. By default, all content types are compressed.
# :sync :: determines if the stream is going to be flushed after every chunk. Flushing after every chunk reduces
# latency for time-sensitive streaming applications, but hurts compression and throughput.
# Defaults to +true+.

### This middleware provides hooks to certain places in the request /
# response lifecycle. This is so that middleware that don't need to filter
# the response data can safely leave it alone and not have to send messages
# down the traditional "rack stack".
#
# The events are:
#
# * on_start(request, response)
#
# This event is sent at the start of the request, before the next
# middleware in the chain is called. This method is called with a request
# object, and a response object. Right now, the response object is always
# nil, but in the future it may actually be a real response object.
#
# * on_commit(request, response)
#
# The response has been committed. The application has returned, but the
# response has not been sent to the webserver yet. This method is always
# called with a request object and the response object. The response
# object is constructed from the rack triple that the application returned.
# Changes may still be made to the response object at this point.
#
# * on_send(request, response)
#
# The webserver has started iterating over the response body and presumably
# has started sending data over the wire. This method is always called with
# a request object and the response object. The response object is
# constructed from the rack triple that the application returned. Changes
# SHOULD NOT be made to the response object as the webserver has already
# started sending data. Any mutations will likely result in an exception.
#
# * on_finish(request, response)
#
# The webserver has closed the response, and all data has been written to
# the response socket. The request and response object should both be
# read-only at this point. The body MAY NOT be available on the response
# object as it may have been flushed to the socket.
#
# * on_error(request, response, error)
#
# An exception has occurred in the application or an `on_commit` event.
# This method will get the request, the response (if available) and the
# exception that was raised.
#
# ## Order
#
# `on_start` is called on the handlers in the order that they were passed to
# the constructor. `on_commit`, on_send`, `on_finish`, and `on_error` are
# called in the reverse order. `on_finish` handlers are called inside an
# `ensure` block, so they are guaranteed to be called even if something
# raises an exception. If something raises an exception in a `on_finish`
# method, then nothing is guaranteed.

## == The Environment
##
def check_environment(env)

## CGI-like headers. The Rack application is free to modify the
## environment.
raise LintError, "env #{env.inspect} is not a Hash, but #{env.class}" unless env.kind_of? Hash
raise LintError, "env should not be frozen, but is" if env.frozen?
##
## The environment is required to include these variables
## (adopted from {PEP 333}[https://peps.python.org/pep-0333/]), except when they'd be empty, but see
## below.
## <tt>REQUEST_METHOD</tt>:: The HTTP request method, such as
## "GET" or "POST". This cannot ever
## be an empty string, and so is
## always required.
## <tt>SCRIPT_NAME</tt>:: The initial portion of the request
## URL's "path" that corresponds to the
## application object, so that the
## application knows its virtual
## "location". This may be an empty
## string, if the application corresponds
## to the "root" of the server.
## <tt>PATH_INFO</tt>:: The remainder of the request URL's
## "path", designating the virtual
## "location" of the request's target
## within the application. This may be an
## empty string, if the request URL targets
## the application root and does not have a
## trailing slash. This value may be
## percent-encoded when originating from
## a URL.
## <tt>QUERY_STRING</tt>:: The portion of the request URL that
## follows the <tt>?</tt>, if any. May be
## empty, but is always required!
## <tt>SERVER_NAME</tt>:: When combined with <tt>SCRIPT_NAME</tt> and
## <tt>PATH_INFO</tt>, these variables can be
## used to complete the URL. Note, however,
## that <tt>HTTP_HOST</tt>, if present,
## should be used in preference to
## <tt>SERVER_NAME</tt> for reconstructing
## the request URL.
## <tt>SERVER_NAME</tt> can never be an empty
## string, and so is always required.
## <tt>SERVER_PORT</tt>:: An optional +Integer+ which is the port the
## server is running on. Should be specified if
## the server is running on a non-standard port.
## <tt>SERVER_PROTOCOL</tt>:: A string representing the HTTP version used
## for the request.
## <tt>HTTP_</tt> Variables:: Variables corresponding to the
## client-supplied HTTP request
## headers (i.e., variables whose
## names begin with <tt>HTTP_</tt>). The
## presence or absence of these
## variables should correspond with
## the presence or absence of the
## appropriate HTTP header in the
## request. See
## {RFC3875 section 4.1.18}[https://tools.ietf.org/html/rfc3875#section-4.1.18]
## for specific behavior.
## In addition to this, the Rack environment must include these
## Rack-specific variables:
## <tt>rack.url_scheme</tt>:: +http+ or +https+, depending on the
## request URL.
## <tt>rack.input</tt>:: See below, the input stream.
## <tt>rack.errors</tt>:: See below, the error stream.
## <tt>rack.hijack?</tt>:: See below, if present and true, indicates
## that the server supports partial hijacking.
## <tt>rack.hijack</tt>:: See below, if present, an object responding
## to +call+ that is used to perform a full
## hijack.
## Additional environment specifications have approved to
## standardized middleware APIs. None of these are required to
## be implemented by the server.
## <tt>rack.session</tt>:: A hash-like interface for storing
## request session data.
## The store must implement:
if session = env[RACK_SESSION]
## store(key, value) (aliased as []=);
unless session.respond_to?(:store) && session.respond_to?(:[]=)
raise LintError, "session #{session.inspect} must respond to store and []="
end
## fetch(key, default = nil) (aliased as []);
unless session.respond_to?(:fetch) && session.respond_to?(:[])
raise LintError, "session #{session.inspect} must respond to fetch and []"
end
## delete(key);
unless session.respond_to?(:delete)
raise LintError, "session #{session.inspect} must respond to delete"
end
## clear;
unless session.respond_to?(:clear)
raise LintError, "session #{session.inspect} must respond to clear"
end
## to_hash (returning unfrozen Hash instance);
unless session.respond_to?(:to_hash) && session.to_hash.kind_of?(Hash) && !session.to_hash.frozen?
raise LintError, "session #{session.inspect} must respond to to_hash and return unfrozen Hash instance"
end
end
## <tt>rack.logger</tt>:: A common object interface for logging messages.
## The object must implement:
if logger = env[RACK_LOGGER]
## info(message, &block)
unless logger.respond_to?(:info)
raise LintError, "logger #{logger.inspect} must respond to info"
end
## debug(message, &block)

unless logger.respond_to?(:error)
raise LintError, "logger #{logger.inspect} must respond to error"
end
## fatal(message, &block)
unless logger.respond_to?(:fatal)
raise LintError, "logger #{logger.inspect} must respond to fatal"
end
end
## <tt>rack.multipart.buffer_size</tt>:: An Integer hint to the multipart parser as to what chunk size to use for reads and writes.
if bufsize = env[RACK_MULTIPART_BUFFER_SIZE]
unless bufsize.is_a?(Integer) && bufsize > 0
raise LintError, "rack.multipart.buffer_size must be an Integer > 0 if specified"
end
end
## <tt>rack.multipart.tempfile_factory</tt>:: An object responding to #call with two arguments, the filename and content_type given for the multipart form field, and returning an IO-like object that responds to #<< and optionally #rewind. This factory will be used to instantiate the tempfile for each multipart form file upload field, rather than the default class of Tempfile.

## === Hijacking
##
## The hijacking interfaces provides a means for an application to take
## control of the HTTP connection. There are two distinct hijack
## interfaces: full hijacking where the application takes over the raw
## connection, and partial hijacking where the application takes over
## just the response body stream. In both cases, the application is
## responsible for closing the hijacked stream.
##
## Full hijacking only works with HTTP/1. Partial hijacking is functionally
## equivalent to streaming bodies, and is still optionally supported for
## backwards compatibility with older Rack versions.
##
## ==== Full Hijack
##
## Full hijack is used to completely take over an HTTP/1 connection. It
## occurs before any headers are written and causes the request to
## ignores any response generated by the application.
##
## It is intended to be used when applications need access to raw HTTP/1
## connection.
##

## to the underlying connection using HTTP/1 semantics and
## formatting.
raise LintError, "rack.hijack must return an IO instance" unless io.is_a?(IO)
io
end
end
end
##
## ==== Partial Hijack
##
## Partial hijack is used for bi-directional streaming of the request and
## response body. It occurs after the status and headers are written by
## the server and causes the server to ignore the Body of the response.
##
## It is intended to be used when applications need bi-directional
## streaming.
##
def check_hijack_response(headers, env)
## If +rack.hijack?+ is present in +env+ and truthy,
if env[RACK_IS_HIJACK]
## an application may set the special response header +rack.hijack+
if original_hijack = headers[RACK_HIJACK]

raise LintError, 'rack.hijack header must respond to #call'
end
## accepting a +stream+ argument.
return proc do |io|
original_hijack.call StreamWrapper.new(io)
end
end
##
## After the response status and headers have been sent, this hijack
## callback will be invoked with a +stream+ argument which follows the
## same interface as outlined in "Streaming Body". Servers must
## ignore the +body+ part of the response tuple when the
## +rack.hijack+ response header is present. Using an empty +Array+
## instance is recommended.

## to be a Streaming Body.
##
## A Body that responds to both +each+ and +call+ must be treated as an
## Enumerable Body, not a Streaming Body. If it responds to +each+, you
## must call +each+ and not +call+. If the Body doesn't respond to
## +each+, then you can assume it responds to +call+.
##
## The Body must either be consumed or returned. The Body is consumed by
## optionally calling either +each+ or +call+.
## Then, if the Body responds to +close+, it must be called to release
## any resources associated with the generation of the body.
## In other words, +close+ must always be called at least once; typically
## after the web server has sent the response to the client, but also in
## cases where the Rack application makes internal/virtual requests and
## discards the response.
##

##
## After calling +close+, the Body is considered closed and should not
## be consumed again.

##
## If the Body responds to +to_path+, it must return a +String+
## path for the local file system whose contents are identical
## to that produced by calling +each+; this may be used by the
## server as an alternative, possibly more efficient way to
## transport the response. The +to_path+ method does not consume
## the body.

## The Body itself should not be an instance of String, as this will
## break in Ruby 1.9.
##
## Middleware must not call +each+ directly on the Body.
## Instead, middleware can return a new Body that calls +each+ on the
## original Body, yielding at least once per iteration.
if @lint[0] == self

## contents are identical to that produced by calling +each+.
## Middleware may call +to_ary+ directly on the Body and return a new
## Body in its place. In other words, middleware can only process the
## Body directly if it responds to +to_ary+. If the Body responds to both
## +to_ary+ and +close+, its implementation of +to_ary+ must call
## +close+.

## <tt>read, write, <<, flush, close, close_read, close_write, closed?</tt>
##

end
class StreamWrapper
extend Forwardable
## The semantics of these IO methods must be a best effort match to
## those of a normal Ruby IO or Socket object, using standard arguments
## and raising standard exceptions. Servers are encouraged to simply
## pass on real IO objects, although it is recognized that this approach
## is not directly compatible with HTTP/2.

## == Thanks
## Some parts of this specification are adopted from {PEP 333 – Python Web Server Gateway Interface v1.0}[https://peps.python.org/pep-0333/]
## I'd like to thank everyone involved in that effort.

module Rack
# = Sendfile
#
# The Sendfile middleware intercepts responses whose body is being
# served from a file and replaces it with a server specific x-sendfile
# header. The web server is then responsible for writing the file contents
# to the client. This can dramatically reduce the amount of work required
# by the Ruby backend and takes advantage of the web server's optimized file
# delivery code.
#
# In order to take advantage of this middleware, the response body must
# respond to +to_path+ and the request must include an x-sendfile-type
# header. Rack::Files and other components implement +to_path+ so there's
# rarely anything you need to do in your application. The x-sendfile-type
# header is typically set in your web servers configuration. The following
# sections attempt to document
#
# === Nginx
#
# Nginx supports the x-accel-redirect header. This is similar to x-sendfile
# but requires parts of the filesystem to be mapped into a private URL
# hierarchy.
#
# The following example shows the Nginx configuration required to create
# a private "/files/" area, enable x-accel-redirect, and pass the special
# x-sendfile-type and x-accel-mapping headers to the backend:
#
# location ~ /files/(.*) {
# internal;
# alias /var/www/$1;
# }
#
# location / {
# proxy_redirect off;
#
# proxy_set_header Host $host;
# proxy_set_header X-Real-IP $remote_addr;
# proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
#
# proxy_set_header x-sendfile-type x-accel-redirect;
# proxy_set_header x-accel-mapping /var/www/=/files/;
#
# proxy_pass http://127.0.0.1:8080/;
# }
#
# Note that the x-sendfile-type header must be set exactly as shown above.
# The x-accel-mapping header should specify the location on the file system,
# followed by an equals sign (=), followed name of the private URL pattern
# that it maps to. The middleware performs a simple substitution on the
# resulting path.
#
# See Also: https://www.nginx.com/resources/wiki/start/topics/examples/xsendfile
#
# === lighttpd
#
# Lighttpd has supported some variation of the x-sendfile header for some
# time, although only recent version support x-sendfile in a reverse proxy
# configuration.
#
# $HTTP["host"] == "example.com" {
# proxy-core.protocol = "http"
# proxy-core.balancer = "round-robin"
# proxy-core.backends = (
# "127.0.0.1:8000",
# "127.0.0.1:8001",
# ...
# )
#
# proxy-core.allow-x-sendfile = "enable"
# proxy-core.rewrite-request = (
# "x-sendfile-type" => (".*" => "x-sendfile")
# )
# }
#
# See Also: http://redmine.lighttpd.net/wiki/lighttpd/Docs:ModProxyCore
#
# === Apache
#
# x-sendfile is supported under Apache 2.x using a separate module:
#
# https://tn123.org/mod_xsendfile/
#
# Once the module is compiled and installed, you can enable it using
# XSendFile config directive:
#
# RequestHeader Set x-sendfile-type x-sendfile
# ProxyPassReverse / http://localhost:8001/
# XSendFile on
#
# === Mapping parameter
#
# The third parameter allows for an overriding extension of the
# x-accel-mapping header. Mappings should be provided in tuples of internal to
# external. The internal values may contain regular expression syntax, they
# will be matched with case indifference.

module Rack
# The Rack::Static middleware intercepts requests for static files
# (javascript files, images, stylesheets, etc) based on the url prefixes or
# route mappings passed in the options, and serves them using a Rack::Files
# object. This allows a Rack stack to serve both static and dynamic content.
#
# Examples:
#
# Serve all requests beginning with /media from the "media" folder located
# in the current directory (ie media/*):
#
# use Rack::Static, :urls => ["/media"]
#
# Same as previous, but instead of returning 404 for missing files under
# /media, call the next middleware:
#
# use Rack::Static, :urls => ["/media"], :cascade => true
#
# Serve all requests beginning with /css or /images from the folder "public"
# in the current directory (ie public/css/* and public/images/*):
#
# use Rack::Static, :urls => ["/css", "/images"], :root => "public"
#
# Serve all requests to / with "index.html" from the folder "public" in the
# current directory (ie public/index.html):
#
# use Rack::Static, :urls => {"/" => 'index.html'}, :root => 'public'
#
# Serve all requests normally from the folder "public" in the current
# directory but uses index.html as default route for "/"
#
# use Rack::Static, :urls => [""], :root => 'public', :index =>
# 'index.html'
#
# Set custom HTTP Headers for based on rules:
#
# use Rack::Static, :root => 'public',
# :header_rules => [
# [rule, {header_field => content, header_field => content}],
# [rule, {header_field => content}]
# ]
#
# Rules for selecting files:
#
# 1) All files
# Provide the :all symbol
# :all => Matches every file
#
# 2) Folders
# Provide the folder path as a string
# '/folder' or '/folder/subfolder' => Matches files in a certain folder
#
# 3) File Extensions
# Provide the file extensions as an array
# ['css', 'js'] or %w(css js) => Matches files ending in .css or .js
#
# 4) Regular Expressions / Regexp
# Provide a regular expression
# %r{\.(?:css|js)\z} => Matches files ending in .css or .js
# /\.(?:eot|ttf|otf|woff2|woff|svg)\z/ => Matches files ending in
# the most common web font formats (.eot, .ttf, .otf, .woff2, .woff, .svg)
# Note: This Regexp is available as a shortcut, using the :fonts rule
#
# 5) Font Shortcut
# Provide the :fonts symbol
# :fonts => Uses the Regexp rule stated right above to match all common web font endings
#
# Rule Ordering:
# Rules are applied in the order that they are provided.
# List rather general rules above special ones.
#
# Complete example use case including HTTP header rules:
#
# use Rack::Static, :root => 'public',
# :header_rules => [
# # Cache all static files in public caches (e.g. Rack::Cache)
# # as well as in the browser
# [:all, {'cache-control' => 'public, max-age=31536000'}],
#
# # Provide web fonts with cross-origin access-control-headers
# # Firefox requires this when serving assets using a Content Delivery Network
# [:fonts, {'access-control-allow-origin' => '*'}]
# ]
