|
||||
|
||||
|
||||
## 3.0.0 - 2017-08-04
|
||||
|
||||
This new version includes a major redesign of the library internals, with the goal to drastically improve the lookup time while reducing storage space.
|
||||
|
||||
For this reason, several public methods that are no longer applicable have been deprecated and/or removed. You can find more information at #133.
|
||||
|
||||
### Changed
|
||||
|
||||
- Updated definitions.
|
||||
- Dropped support for Ruby < 2.1
|
||||
- `PublicSuffix::List#rules` is now protected. You should not rely on it as the internal rule representation is subject to change to optimize performances.
|
||||
- Removed `PublicSuffix::List.clear`, it was an unnecessary accessor method. Use `PublicSuffix::List.default = nil` if you **really** need to reset the default list. You shouldn't.
|
||||
- `PublicSuffix::List#select` is now private. You should not use it, instead use `PublicSuffix::List#find`.
|
||||
- `PublicSuffix::List` no longer implements Enumerable. Instead, use `#each` to loop over, or get an Enumerator.
|
||||
- Redesigned internal list storage and lookup algorithm to achieve O(1) lookup time (see #133).
|
||||
|
||||
|
||||
## 2.0.5 - 2017-01-02
|
||||
|
||||
### Changed
|
||||
|
||||
- Updated definitions.
|
||||
- Initialization performance improvements #128. (Thanks @casperisfine)
|
||||
|
||||
|
||||
## 2.0.4 - 2016-11-07
|
||||
|
||||
### Fixed
|
||||
|
||||
- Fixed a bug that caused the GEM to be published with the wrong version number in the gemspec #121.
|
||||
|
||||
### Changed
|
||||
|
||||
- Updated definitions.
|
||||
|
||||
|
||||
## 2.0.3 - 2016-09-30
|
||||
|
||||
### Changed
|
||||
|
||||
- Updated definitions.
|
||||
|
||||
|
||||
## 2.0.2 - 2016-06-10
|
||||
|
||||
### Changed
|
||||
|
||||
- Updated definitions.
|
||||
|
||||
|
||||
## 2.0.1 - 2016-05-22
|
||||
|
||||
### Fixed
|
||||
|
||||
- Fix bug that prevented .valid? to reset the default rule
|
||||
|
||||
|
||||
## 2.0.0 - 2016-05-20
|
||||
|
||||
### Added
|
||||
|
||||
- Added PublicSuffix.domain # => sld.tld
|
||||
- Added the ability to disable the use of private domains either at runtime, in addition to the ability to not load the private domains section when reading the list (`private_domains: false`). This feature also superseded the `private_domains` class-level attribute, that is no longer available.
|
||||
|
||||
### Changed
|
||||
|
||||
- Considerable performance improvements #92
|
||||
- Updated definitions.
|
||||
- Removed deprecated PublicSuffix::InvalidDomain exception
|
||||
- If the suffix is now listed, then the prevaling rule is "*" as defined by the PSL algorithm #91
|
||||
- Input validation is performed only if you call `PublicSuffix.parse` or `PublicSuffix.list`
|
||||
- Input with leading dot is invalid per PSL acceptance tests
|
||||
- Removed `private_domains` class-level attribute. It is replaced by the `private_domains: false` option in the list parse method.
|
||||
- The default list now assumes you use UTF-8 for reading the input #94,
|
||||
|
||||
### Removed
|
||||
|
||||
- Removed futile utility helpers such as `Domain#rule`, `Domain#is_a_domain?`, `Domain#is_a_subdomain?`, `Domain#valid?`. You can easily obtain the same result by having a custom method that reconstructs the logic, and/or calling `PublicSuffix.{domain|parse}(domain.to_s)`.
|
||||
|
||||
|
||||
## 1.5.3 - 2015-12-14

|
||||
|
||||
|
||||
## 0.3.1 - 2010-05-31
|
||||
|
||||
### Changed
|
||||
|
||||
- Deprecated DomainName library.
|
||||
|
||||
|
||||
## 0.3.0 - 2010-05-31
|
||||
|
||||
### Changed
|
||||
|
||||
- DomainName#domain and DomainName#subdomain are no longer alias of Domain#sld and Domain#tld.
|
||||
- Removed DomainName#labels and decoupled Rule from DomainName.
|
||||
- DomainName#valid? no longer instantiates new DomainName objects. This means less overhead.
|
||||
- Refactoring the entire DomainName API. Removed the internal on-the-fly parsing. Added a bunch of new methods to check and validate the DomainName.
|
||||
|
||||
|
||||
## 0.2.0 - 2010-05-31
|
||||
|
||||
### Added
|
||||
|
||||
- DomainName#valid?
|
||||
- DomainName#parse and DomainName#parse!
|
||||
- DomainName#valid_domain? and DomainName#valid_subdomain?
|
||||
|
||||
### Changed
|
||||
|
||||
- Make sure RuleList lookup is only performed once.
|
||||
|
||||
|
||||
## 0.1.0 - 2010-05-31

# PublicSuffix for Ruby
|
||||
|
||||
`PublicSuffix` is a Ruby domain name parser based on the [Public Suffix List](https://publicsuffix.org/).
|
||||

||||
|
||||

|
||||
- [Repository](https://github.com/weppos/publicsuffix-ruby)
|

|
||||
- [Introducing the Public Suffix List library for Ruby](https://simonecarletti.com/blog/2010/06/public-suffix-list-library-for-ruby/)
|
||||
|
||||
|
||||
## Requirements
|
||||
|
||||
`PublicSuffix` requires **Ruby >= 3.2**. For older versions of Ruby, use a previous release.
|
||||
|
||||
|
||||
## Installation
|
||||
|
||||
You can install the gem manually:
|
||||
|
||||
```shell
|
||||
gem install public_suffix
|
||||
```
|
||||
|
||||
Or use Bundler and define it as a dependency in your `Gemfile`:
|
||||
|
||||
```ruby
|
||||
gem 'public_suffix'
|
||||
```
|
||||
|
||||
## Usage
|
||||
|
||||
Extract the domain out from a name:
|
||||
|
||||
```ruby
|
||||
PublicSuffix.domain("google.com")
|
||||
# => "google.com"
|
||||
PublicSuffix.domain("www.google.com")
|
||||
# => "google.com"
|
||||
PublicSuffix.domain("www.google.co.uk")
|
||||
# => "google.co.uk"
|
||||
```
|
||||
|
||||
Parse a domain without subdomains:
|
||||
|
||||
```ruby
|
||||
domain = PublicSuffix.parse("google.com")
|
||||
# => #<PublicSuffix::Domain>
|
||||
domain.tld
|
||||
# => "com"
|
||||
domain.sld
|
||||
# => "google"
|
||||
domain.trd
|
||||
# => nil
|
||||
domain.domain
|
||||
# => "google.com"
|
||||
domain.subdomain
|
||||
# => nil
|
||||
```
|
||||
|
||||
Parse a domain with subdomains:
|
||||
|
||||
```ruby
|
||||
domain = PublicSuffix.parse("www.google.com")
|
||||
# => #<PublicSuffix::Domain>
|
||||
domain.tld
|
||||
# => "com"
|
||||
domain.sld
|
||||
# => "google"
|
||||
domain.trd
|
||||
# => "www"
|
||||
domain.domain
|
||||
# => "google.com"
|
||||
domain.subdomain
|
||||
# => "www.google.com"
|
||||
```
|
||||
|
||||
Simple validation example:
|
||||
|
||||
```ruby
|
||||
PublicSuffix.valid?("google.com")
|
||||
# => true
|
||||
|
||||
PublicSuffix.valid?("www.google.com")
|
||||
# => true
|
||||
|
||||
# Explicitly forbidden, it is listed as a private domain
|
||||
PublicSuffix.valid?("blogspot.com")
|
||||
# => false
|
||||
|
||||
# Unknown/not-listed TLD domains are valid by default
|
||||
PublicSuffix.valid?("example.tldnotlisted")
|
||||
# => true
|
||||
```
|
||||
|
||||
Strict validation (without applying the default * rule):
|
||||
|
||||
```ruby
|
||||
PublicSuffix.valid?("example.tldnotlisted", default_rule: nil)
|
||||
# => false
|
||||
```
|
||||
|
||||
|
||||
## Fully qualified domain names
|
||||
|
||||
This library automatically recognizes Fully Qualified Domain Names. A FQDN is a domain name that ends with a trailing dot.
|
||||
|
||||
```ruby
|
||||
# Parse a standard domain name
|
||||
PublicSuffix.domain("www.google.com")
|
||||
# => "google.com"
|
||||
|
||||
# Parse a fully qualified domain name
|
||||
PublicSuffix.domain("www.google.com.")
|
||||
# => "google.com"
|
||||
```
|
||||
|
||||
## Private domains
|
||||
|
||||
This library supports toggling private (non-ICANN) domain handling.
|
||||
|
||||
```ruby
|
||||
# Extract a domain including private domains (by default)
|
||||
PublicSuffix.domain("something.blogspot.com")
|
||||
# => "something.blogspot.com"
|
||||
|
||||
# Extract a domain excluding private domains
|
||||
PublicSuffix.domain("something.blogspot.com", ignore_private: true)
|
||||
# => "blogspot.com"
|
||||
|
||||
# It also works for #parse and #valid?
|
||||
PublicSuffix.parse("something.blogspot.com", ignore_private: true)
|
||||
PublicSuffix.valid?("something.blogspot.com", ignore_private: true)
|
||||
```
|
||||
|
||||
If you don't care about private domains at all, it's more efficient to exclude them when the list is parsed:
|
||||
|
||||
```ruby
|
||||
# Disable support for private TLDs
|
||||
PublicSuffix::List.default = PublicSuffix::List.parse(File.read(PublicSuffix::List::DEFAULT_LIST_PATH), private_domains: false)
|
||||
# => "blogspot.com"
|
||||
PublicSuffix.domain("something.blogspot.com")
|
||||
# => "blogspot.com"
|
||||
```
|
||||
|
||||
## Adding custom domains
|
||||
|
||||
To manually add a domain to the list:
|
||||
|
||||
```ruby
|
||||
PublicSuffix::List.default << PublicSuffix::Rule.factory('onmicrosoft.com')
|
||||
```
|
||||
|
||||
## What is the public suffix list?
|
||||
|
||||
The [Public Suffix List](https://publicsuffix.org) is a cross-vendor initiative to provide an accurate list of domain name suffixes.
|
||||
|
||||
The Public Suffix List is an initiative of the Mozilla Project, but is maintained as a community resource. It is available for use in any software, but was originally created to meet the needs of browser manufacturers.
|
||||
|
||||
A "public suffix" is one under which Internet users can directly register names. Some examples of public suffixes are ".com", ".co.uk" and "pvt.k12.wy.us". The Public Suffix List is a list of all known public suffixes.
|
||||
|
||||
|
||||
## Why use the public suffix list instead of regular expressions?
|
||||
|
||||
Previously, browsers used an algorithm which basically only denied setting wide-ranging cookies for top-level domains with no dots (e.g. com or org). However, this did not work for top-level domains where only third-level registrations are allowed (e.g. co.uk). In these cases, websites could set a cookie for co.uk which will be passed onto every website registered under co.uk.
|
||||
|
||||
Clearly, this was a security risk as it allowed websites other than the one setting the cookie to read it, and therefore potentially extract sensitive information.
|
||||
|
||||
Since there is no algorithmic method of finding the highest level at which a domain may be registered for a particular top-level domain (the policies differ with each registry), the only method is to create a list of all top-level domains and the level at which domains can be registered. This is the aim of the effective TLD list.
|
||||
|
||||
As well as being used to prevent cookies from being set where they shouldn't be, the list can also potentially be used for other applications where the registry controlled and privately controlled parts of a domain name need to be known, for example when grouping by top-level domains.

|
||||
|
||||
|
||||
## Does PublicSuffix make network requests?
|
||||
|
||||
No. `PublicSuffix` comes with a bundled list. It does not make any HTTP requests to parse or validate a domain.
|
||||
|
||||
|
||||
## Terminology
|
||||
|
||||
- **TLD** (Top-Level Domain): The last segment of a domain name. For example, in `mozilla.org`, the `.org` portion is the TLD.
|
||||
|
||||
- **SLD** (Second-Level Domain): A domain directly below a top-level domain. For example, in `https://www.mozilla.org/en-US/`, `mozilla` is the second-level domain of the `.org` TLD.
|
||||
|
||||
- **TRD** (Third-Level Domain): Also known as a subdomain, this is the part of the domain before the SLD or root domain. For example, in `https://www.mozilla.org/en-US/`, `www` is the TRD.
|
||||
|
||||
- **FQDN** (Fully Qualified Domain Name): A complete domain name that includes the hostname, domain, and top-level domain, ending with a trailing dot. The format is `[hostname].[domain].[tld].` (e.g., `www.mozilla.org.`).

#

# = Abstract rule class
|
||||
#
|
||||
# This represent the base class for a Rule definition
|
||||
# in the {Public Suffix List}[https://publicsuffix.org].
|
||||
#
|
||||
# This is intended to be an Abstract class
|
||||
# and you shouldn't create a direct instance. The only purpose
|
||||
# of this class is to expose a common interface
|
||||
# for all the available subclasses.

||||
#
|
||||
# * {PublicSuffix::Rule::Normal}
|
||||
# * {PublicSuffix::Rule::Exception}
|
||||
# * {PublicSuffix::Rule::Wildcard}
|
||||
#
|
||||
# ## Properties
|
||||
#
|
||||
# A rule is composed by 4 properties:
|
||||
#
|
||||
# value - A normalized version of the rule name.
|
||||
# The normalization process depends on rule tpe.
|
||||
#
|
||||
# Here's an example
|
||||
#
|
||||
# PublicSuffix::Rule.factory("*.google.com")
|
||||
# #<PublicSuffix::Rule::Wildcard:0x1015c14b0
|
||||
# @value="google.com"
|
||||
# >
|
||||
#
|
||||
# ## Rule Creation
|
||||
#
|
||||
# The best way to create a new rule is passing the rule name
|
||||
# to the <tt>PublicSuffix::Rule.factory</tt> method.
|
||||
#
|
||||
# PublicSuffix::Rule.factory("com")
|
||||
# # => PublicSuffix::Rule::Normal
|
||||
#
|
||||
# PublicSuffix::Rule.factory("*.com")
|
||||
# # => PublicSuffix::Rule::Wildcard
|
||||
#
|
||||
# This method will detect the rule type and create an instance
|
||||
# from the proper rule class.
|
||||
#
|
||||
# ## Rule Usage
|
||||
#
|
||||
# A rule describes the composition of a domain name and explains how to tokenize
|
||||
# the name into tld, sld and trd.
|
||||
#
|
||||
# To use a rule, you first need to be sure the name you want to tokenize
|
||||
# can be handled by the current rule.
|
||||
# You can use the <tt>#match?</tt> method.
|
||||
#
|
||||
# rule = PublicSuffix::Rule.factory("com")
|
||||
#
|
||||
# rule.match?("google.com")
|
||||
# # => true
|
||||
#
|
||||
# rule.match?("google.com")
|
||||
# # => false
|
||||
#
|
||||
# Rule order is significant. A name can match more than one rule.
|
||||
# See the {Public Suffix Documentation}[http://publicsuffix.org/format/]
|
||||
# to learn more about rule priority.
|
||||
#
|
||||
# When you have the right rule, you can use it to tokenize the domain name.

||||
#
|
||||
# rule = PublicSuffix::Rule.factory("com")
