publicsuffix-erl

Erlang interface to the Public Suffix List.

The Public Suffix List (PSL) is a set of rules describing "effective top-level domains" and can be used to determine the registered domain for a given host name.

Inspired by publicsuffix_erlang (but supports unicode TLDs too) and tld.

Requirements

Erlang 17.0 or newer (should work on R16 too but hasn't been tested)
GNU make

Installation

git clone https://github.com/Mendor/publicsuffix-erl.git
cd publicsuffix-erl
make

Usage

[inori] ~/dev/my/publicsuffix-erl % erl +pc unicode -pa ebin
Erlang/OTP 17 [erts-6.3] [source] [64-bit] [smp:4:4] [async-threads:10] [hipe] [kernel-poll:false] [dtrace]

Eshell V6.3  (abort with ^G)
1> tld:domain(<<"some.site.co.uk">>).
<<"site.co.uk">>
2> tld:domain(<<"тут.какой-то.сайт"/utf8>>).   % unicode domains work!
<<"какой-то.сайт"/utf8>>
3> tld:domain(<<"https://www.google.com/">>).  % and extracting domain from the whole URI
<<"google.com">>
4> tld:suffix(<<"ポイント.ストア"/utf8>>).       % and if you need only the suffix
<<"ストア"/utf8>>

TODO
