Some parts adapted from golang.org/src/pkg/json/decode.go and golang.org/src/pkg/utf8/utf8.go

Public Instance Methods

decode(string, options = {}) click to toggle source

Decode a JSON string into Ruby.

Options

:symbolize_keys

If true, will use symbols instead of strings for the keys.

# File lib/multi_json.rb, line 75
def decode(string, options = {})
  engine.decode(string, options)
rescue engine::ParseError => exception
  raise DecodeError.new(exception.message, exception.backtrace, string)
end
default_engine() click to toggle source

The default engine based on what you currently have loaded and installed. First checks to see if any engines are already loaded, then checks to see which are installed if none are loaded.

# File lib/multi_json.rb, line 34
def default_engine
  return :yajl if defined?(::Yajl)
  return :json_gem if defined?(::JSON)

  REQUIREMENT_MAP.each do |(library, engine)|
    begin
      require library
      return engine
    rescue LoadError
      next
    end
  end

  Kernel.warn DEFAULT_ENGINE_WARNING
  :ok_json
end
encode(object, options = {}) click to toggle source

Encodes a Ruby object as JSON.

# File lib/multi_json.rb, line 82
def encode(object, options = {})
  engine.encode(object, options)
end
engine() click to toggle source

Get the current engine class.

# File lib/multi_json.rb, line 16
def engine
  return @engine if @engine
  self.engine = self.default_engine
  @engine
end
engine=(new_engine) click to toggle source

Set the JSON parser utilizing a symbol, string, or class. Supported by default are:

  • :json_gem

  • :json_pure

  • :ok_json

  • :yajl

# File lib/multi_json.rb, line 58
def engine=(new_engine)
  case new_engine
  when String, Symbol
    require "multi_json/engines/#{new_engine}"
    @engine = MultiJson::Engines.const_get("#{new_engine.to_s.split('_').map{|s| s.capitalize}.join('')}")
  when Class
    @engine = new_engine
  else
    raise "Did not recognize your engine specification. Please specify either a symbol or a class."
  end
end
