Requirements

• mruby >= 1.3.0

PublicSuffix class methods

PublicSuffix.domain

PublicSuffix.domain extracts the domain out from a given name and returns it as String class.

PublicSuffix.domain('google.com')
# => "google.com"

If given a domain with subdomains, returning the domain.

PublicSuffix.domain('www.google.com')
# => "google.com"
PublicSuffix.domain('www.google.co.uk')
# => "google.co.uk"

This library automatically recognizes FQDN (Fully Qualified Domain Names). A FQDN is a domain name that end with a trailing dot.

PublicSuffix.domain("www.google.com.")
# => "google.com"

PublicSuffix.parse

PublicSuffix.parse parses a domain and returns an object of PublicSuffix::Domain class. This method support a domain with subdomains.

domain = PublicSuffix.parse('www.google.com')
# => #<PublicSuffix::Domain:0x7fa3bf84c9b0>

PublicSuffix.valid?

Checks whether a given domain is assigned and allowed, without actually parsing it. This method doesn't care whether domain is a domain or subdomain. The validation is performed using the default PublicSuffix::List.

Simple validation example:

PublicSuffix.valid?("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):

> PublicSuffix.valid?("example.tldnotlisted", PublicSuffix::List.default, nil)
# => false
