public_suffix_list

Build Status

Simple Lua interface to the Public Suffix List rules, intended to be used a building block for implementing the PSL domain parsing algorithm. New Luarocks builds are automatically created each month using the latest Public Suffix List.

local public_suffix_list = require('public_suffix_list')

if public_suffix_list.exists('com') then
  -- ...
end

Installation

With Luarocks:

luarocks install public_suffix_list

Generating

Note: public_suffix_list.lua is not checked into the repository. Instead, public_suffix_list.dat is parsed and converted into a Lua table that is then used to create public_suffix_list.lua (from public_suffix_list.in.lua).

  • Clone this repository
  • Download public_suffix_list.dat from here or here
  • Run lua generate.lua
