#- NOTE ------------------------------------------------------------------#
# The order of the methods defined in this file and the order of the
# methods is relevant for the documentation generated on the
# CocoaPods/cocoapods.github.com repository.
#-------------------------------------------------------------------------#
# A specification describes a version of Pod library. It includes details
# about where the source should be fetched from, what files to use, the
# build settings to apply, and other general metadata such as its name,
# version, and description.
#
# ---
#
# A stub specification file can be generated by the [pod spec
# create](http://guides.cocoapods.org/terminal/commands.html#pod_spec_create) command.
#
# ---
#
# The specification DSL provides great flexibility and dynamism. Moreover,
# the DSL adopts the
# [convention over configuration](http://en.wikipedia.org/wiki/Convention_over_configuration)
# and thus it can be very simple:
#
# Pod::Spec.new do |spec|
# spec.name = 'Reachability'
# spec.version = '3.1.0'
# spec.license = { :type => 'BSD' }
# spec.homepage = 'https://github.com/tonymillion/Reachability'
# spec.authors = { 'Tony Million' => 'tonymillion@gmail.com' }
# spec.summary = 'ARC and GCD Compatible Reachability Class for iOS and OS X.'
# spec.source = { :git => 'https://github.com/tonymillion/Reachability.git', :tag => 'v3.1.0' }
# spec.source_files = 'Reachability.{h,m}'
# spec.framework = 'SystemConfiguration'
# end
#
# Or it can be quite detailed:
#
# Pod::Spec.new do |spec|
# spec.name = 'Reachability'
# spec.version = '3.1.0'
# spec.license = { :type => 'BSD' }
# spec.homepage = 'https://github.com/tonymillion/Reachability'
# spec.authors = { 'Tony Million' => 'tonymillion@gmail.com' }
# spec.summary = 'ARC and GCD Compatible Reachability Class for iOS and OS X.'
# spec.source = { :git => 'https://github.com/tonymillion/Reachability.git', :tag => 'v3.1.0' }
# spec.module_name = 'Rich'
# spec.swift_version = '4.0'
#
# spec.ios.deployment_target = '9.0'
# spec.osx.deployment_target = '10.10'
#
# spec.source_files = 'Reachability/common/*.swift'
# spec.ios.source_files = 'Reachability/ios/*.swift', 'Reachability/extensions/*.swift'
# spec.osx.source_files = 'Reachability/osx/*.swift'
#
# spec.framework = 'SystemConfiguration'
# spec.ios.framework = 'UIKit'
# spec.osx.framework = 'AppKit'

# @!group Root specification
#
# A ‘root’ specification stores the information about the specific
# version of a library.
#
# The attributes in this group can only be written to on the ‘root’
# specification, **not** on the ‘sub-specifications’.
#
# ---
#
# The attributes listed in this group are the only one which are
# required by a podspec.
#
# The attributes of the other groups are offered to refine the podspec
# and follow a convention over configuration approach. A root
# specification can describe these attributes either directly of
# through ‘[sub-specifications](#subspec)’.
#-----------------------------------------------------------------------#
# @!method name=(name)
#
# The name of the Pod.
#
# @example
#
# spec.name = 'AFNetworking'
#
# @param [String] name
# the name of the pod.
#
attribute :name,
:required => true,
:inherited => false,

#
# @example
#
# spec.version = '0.0.1'
#
# @param [String] version
# the version of the Pod.
#
root_attribute :version,

#------------------#
# @!method swift_versions=(version)
#
# The versions of Swift that the specification supports. A version of '4' will be treated as
# '4.0' by CocoaPods and not '4.1' or '4.2'.
#
# **Note** The Swift compiler mostly accepts major versions and sometimes will honor minor versions.
# While CocoaPods allows specifying a minor or patch version it might not be honored fully by the Swift compiler.
#
# @example
#
# spec.swift_versions = ['3.0']
#
# @example
#
# spec.swift_versions = ['3.0', '4.0', '4.2']
#
# @example
#
# spec.swift_version = '3.0'
#
# @example
#
# spec.swift_version = '3.0', '4.0'
#
# @param [String, Array<String>] swift_versions
#
root_attribute :swift_versions,
:container => Array,

#-----------------------------------------------------------------------#
# @!method cocoapods_version=(cocoapods_version)
#
# The version of CocoaPods that the specification supports.
#
# @example
#
# spec.cocoapods_version = '>= 0.36'
#
# @param [String] cocoapods_version
# the CocoaPods version that the specification supports.
# CocoaPods follows [semantic versioning](http://semver.org).
#
root_attribute :cocoapods_version
#------------------#
# @!method authors=(authors)
#
# The name and email addresses of the library maintainers, not the
# Podspec maintainer.
#
# @example
#
# spec.author = 'Darth Vader'
#
# @example
#
# spec.authors = 'Darth Vader', 'Wookiee'
#
# @example
#
# spec.authors = { 'Darth Vader' => 'darthvader@darkside.com',

# the list of the authors of the library and their emails.
#
root_attribute :authors,
:types => [String, Array, Hash],
:container => Hash,
:required => true,

#------------------#
# @!method social_media_url=(social_media_url)
#
# The URL for the social media contact of the Pod, CocoaPods web
# services can use this.
#
# For example, the @CocoaPodsFeed notifications will include the
# Twitter handle (shortening the description) if the URL is relative to
# Twitter. This does **not** necessarily have to be a Twitter URL, but
# only those are included in the Twitter @CocoaPodsFeed notifications.
#
# @example
#
# spec.social_media_url = 'https://twitter.com/cocoapods'
#
# @example
#
# spec.social_media_url = 'https://groups.google.com/forum/#!forum/cocoapods'
#
# @param [String] social_media_url
# the social media URL.
#
root_attribute :social_media_url
#------------------#
# The keys accepted by the license attribute.
#
LICENSE_KEYS = [:type, :file, :text].freeze
# @!method license=(license)
#
# The license of the Pod.

# Dependencies can specify versions requirements. The use of the optimistic

# control over the version without being too restrictive. For example,
# `~> 1.0.1` is equivalent to `>= 1.0.1` combined with `< 1.1`. Similarly,
# `~> 1.0` will match `1.0`, `1.0.1`, `1.1`, but will not upgrade to `2.0`.

# Pods with overly restrictive dependencies limit their compatibility with
# other Pods.

# @example
# spec.dependency 'AFNetworking', '~> 1.0'
