Absolutely

A Ruby gem for converting relative paths to absolute URIs.

Key Features

• Uses the Addressable Ruby gem for improved URI parsing.
• Supports Ruby 2.5 and newer.

Getting Started

Before installing and using Absolutely, you'll want to have Ruby 2.5 (or newer) installed. It's recommended that you use a Ruby version managment tool like rbenv, chruby, or rvm.

Absolutely is developed using Ruby 2.5.8 and is additionally tested against Ruby 2.6, 2.7, and 3.0 using CircleCI.

Installation

If you're using Bundler, add Absolutely to your project's Gemfile:

source 'https://rubygems.org'

gem 'absolutely'

…and hop over to your command prompt and run…

$ bundle install

Usage

Basic Usage

With Absolutely added to your project's Gemfile and installed, you may convert relative URIs to absolute URIs by doing:

require 'absolutely'

uri = Absolutely.uri(base: 'https://example.com', relative: '/foo').to_abs

puts uri # => String: 'https://example.com/foo'

This example combines the supplied base value (https://example.com) and combines it with the supplied relative value (/foo), returning the string https://example.com/foo.

You may obtain the same results using this slightly shorter version:

require 'absolutely'

uri = Absolutely.to_abs(base: 'https://example.com', relative: '/foo')

puts uri # => 'https://example.com/foo'

Note that if the value passed as relative is determined to be an absolute URI, Absolutely will return the value of relative regardless of the value passed as base:

require 'absolutely'

uri = Absolutely.to_abs(base: 'https://example.com', relative: 'https://example.com/foo')

puts uri # => 'https://example.com/foo'

Advanced Usage

Should the need arise, you may work directly with the Absolutely::URI class:

require 'absolutely'

uri = Absolutely::URI.new(base: 'https://example.com', relative: '/foo')

puts uri              # => #<Absolutely::URI>

puts uri.base         # => 'https://example.com'
puts uri.relative     # => '/foo'

puts uri.base_uri     # => #<Addressable::URI URI:https://example.com>
puts uri.relative_uri # => #<Addressable::URI URI:/foo>

puts uri.to_abs       # => 'https://example.com/foo'

For convenience, the base_uri and relative_uri methods return instances of the Addressable::URI class. For more on this class' available methods, see the Addressable Ruby gem's source code.
