Addressabler

Addressabler extends the Addressable::URI class by adding TLD parsing, domain and subdomain parsing, query modification, and restoring setting of nested hashes to query strings.

Install

Add Addressabler to your Gemfile:

gem "addressabler", ">= 0.1"

Addressabler will automatically require addressable/uri.

Usage

Domain, TLD, and subdomain parsing

Use Addressable::URI like you normally would:

@uri = Addressable::URI.parse("http://www.google.com/")
@uri.host #=> "www.google.com"

Addressabler will add the following properties:

@uri.tld #=> "com"
@uri.domain #=> "google"
@uri.subdomain #=> "www"

You can set these values, as well:

@uri.tld = "org"
@uri.host #=> "www.google.org"
@uri.domain = "amazon"
@uri.host #=> "www.amazon.org"
@uri.subdomain = "developers"
@uri.host #=> "developers.amazon.org"

Complex TLD support (thanks to Paul Dix!)

Addressabler copies some of Paul Dix's Domaintrix TLD code to support fancy TLDs, as well:

@uri.host = "www.google.co.uk"
@uri.tld #=> "co.uk"

Private / Public TLDs

By default, Addressabler knows about ICANN public TLDs. There are, however, lots and lots of private TLDs that companies have registered. For example, as Dom Hodgson points out, "blogspot.com" is a TLD by private, non-ICANN standards which are applied by the Mozilla foundation to the TLD list.

As such, Addressabler defaults to parsing the ICANN public TLDS (Addressabler.public_tlds) but can easily be instructed to look at private TLDs like so:

Addressabler.use_private_tlds = true

Custom TLDs

You can specify custom TLDs - which aren't actually working TLD's on the internet - for internal usage. One example would be a custom development TLD:

Addressabler.custom_tlds = {
  'dev' => {},              # mydomain.dev
  'bar' => { 'foo' => {} }  # mydomain.foo.bar
}

Query interface

Addressabler adds a query_hash method to Addressable::URIs. This makes editing query strings a lot simpler, using a familiar Hash syntax:

@uri.query_hash[:foo] = :bar
@uri.to_s #=> "http://www.google.co.uk/?foo=bar"

Nested hashes in query strings

The current maintainer of Addressable, Bob Aman, feels rather strongly that Rails got it wrong in supporting nested hashes in query strings.

Frankly, I don't disagree with anything he has to say on the issue, but it is a problem many people have experienced.

As such, since Rack already supports building nested hashes "the Rails Way" (shudder), I added support for assigning nested hashes to Addressable::URIs only if Rack is available. Addressabler will attempt to load Rack::Utils and, if it finds it, you can assign a nested hash in the query_hash= method like so:

@uri.query_hash = {:foo => {:bar => :baz}}
@uri.to_s #=> "http://www.google.co.uk/?foo[bar]=baz"

HANDLE WITH CARE! As Bob explains in the discussion, there's a better alternative to nested hashes in query strings, so try that before you install this library.

That's it. Enjoy.
