This is a simple gem that provides method-like syntatic sugar on top of a JSON object via the JSONHash class.
If you are using Bundler, simply add the following line to your Gemfile:
gem "json_hash"
Otherwise, just type:
gem install json_hash
The canonical usage is to obtain some JSON text from a remote endpoint, and parse it. For example:
require "json_hash"
=> true
user = JSONHash.parse("http://example.org/users/1.json")
=> #<JSONHash:0x007fe0d320fd30 @json={"id"=>1, ...}
user.id
=> 1
user.login
=> "john_smith"
users = JSONHash.parse("http://example.org/users.json")
=> [#<JSONHash:0x007fe0d322c368 @json={"id"=>1, ...}, ...]
users.count
=> 4
users[1].login
=> "jane_smith" The json_hash gem relies on the following:
- The json gem
- The open-uri module
- The uri module
This was inspired by a similar class I wrote in Python to parse Jenkin's RESTful API output, which made use of the setattr() method. I wanted to see if I can do something similar in Ruby.
Alas, since Ruby doesn't have something like setattr(), I've had to rely on method_missing() instead.
