Addressable

Description

Addressable is an alternative implementation to the URI implementation that is part of Ruby's standard library. It is flexible, offers heuristic parsing, and additionally provides extensive support for IRIs and URI templates.

Addressable closely conforms to RFC 3986, RFC 3987, and RFC 6570 (level 4).

Reference

• {Addressable::URI}
• {Addressable::Template}

Example usage

require "addressable/uri"

uri = Addressable::URI.parse("http://example.com/path/to/resource/")
uri.scheme
#=> "http"
uri.host
#=> "example.com"
uri.path
#=> "/path/to/resource/"

uri = Addressable::URI.parse("http://www.詹姆斯.com/")
uri.normalize
#=> #<Addressable::URI:0xc9a4c8 URI:http://www.xn--8ws00zhy3a.com/>

URI Templates

For more details, see RFC 6570.

require "addressable/template"

template = Addressable::Template.new("http://example.com/{?query*}")
template.expand({
  "query" => {
    'foo' => 'bar',
    'color' => 'red'
  }
})
#=> #<Addressable::URI:0xc9d95c URI:http://example.com/?foo=bar&color=red>

template = Addressable::Template.new("http://example.com/{?one,two,three}")
template.partial_expand({"one" => "1", "three" => 3}).pattern
#=> "http://example.com/?one=1{&two}&three=3"

template = Addressable::Template.new(
  "http://{host}{/segments*}/{?one,two,bogus}{#fragment}"
)
uri = Addressable::URI.parse(
  "http://example.com/a/b/c/?one=1&two=2#foo"
)
template.extract(uri)
#=>
# {
#   "host" => "example.com",
#   "segments" => ["a", "b", "c"],
#   "one" => "1",
#   "two" => "2",
#   "fragment" => "foo"
# }

Install

$ gem install addressable

You may optionally turn on native IDN support by installing libidn and the idn gem:

$ sudo apt-get install libidn11-dev # Debian/Ubuntu
$ brew install libidn # OS X
$ gem install idn-ruby

Semantic Versioning

This project uses Semantic Versioning. You can (and should) specify your dependency using a pessimistic version constraint covering the major and minor values:

spec.add_dependency 'addressable', '~> 2.7'

If you need a specific bug fix, you can also specify minimum tiny versions without preventing updates to the latest minor release:

spec.add_dependency 'addressable', '~> 2.3', '>= 2.3.7'
