Addressable

Description

Addressable is a replacement for the URI implementation that is part of Ruby's standard library. It more closely conforms to RFC 3986, RFC 3987, and RFC 6570 (level 4), providing support for IRIs and URI templates.

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 idn # Debian/Ubuntu
$ brew install libidn # OS X
$ gem install idn-ruby

Semantic Versioning

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

spec.add_dependency 'addressable', '~> 2.5'

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'
