A Ruby implementation for Rison - Compact Data in URIs.

Add this line to your application's Gemfile:

gem 'rison-rb'

And then execute:

$ bundle

Or install it yourself as:

$ gem install rison-rb

This is a Ruby implementation for Rison that represents compact data in URIs. This module provides a parsing and dumping API like JSON module:

require "rison"

Rison.dump({ a: 1, b: true , c: ['foo', 'bar'] }) # => (a:1,b:!t,c:!(foo,bar))
Rison.parse('(a:1,b:!t,c:!(foo,bar))') # => { 'a' => 1, 'b' => true , 'c' => ['foo', 'bar'] }

Parsing generates a hash key as a string, just like JSON module. But you can also switch keys to symbols with the symbolize_names option:

Rison.parse('(a:!(foo,bar,(b:1)))', symbolize_names: true) # => { a: ['foo', 'bar', { b: 1 }] }

Similarly, O-Rison and A-Rison variations are supported:

# O-Rison
Rison.dump({ a: 1, b: 2 }, mode: :object) # => a:1,b:2
Rison.parse('a:1,b:2', mode: :object) # => { 'a' => 1, 'b' => 2 }

# A-Rison
Rison.dump(['foo', 'bar'], mode: :array) # => foo,bar
Rison.parse('foo,bar', mode: :array) # => ['foo', 'bar']

The original syntax defines only alphanumeric and -_./~ as ASCII characters for idchar. But rison.js accepts other ASCII characters as idchar.

rison-rb conforms to the rison.js implementation. Therefore, it differs from the original syntax in the following points:

• It accepts ASCII characters other than <space>'!:(),*@$ and all non-ASCII characters as idchar.
• Numbers starting with 0 are allowed.

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
