Subject: [ANN] Kwalify 0.7.0 - parser, schema validator, and data binding for 	YAML and JSON

Hi,

I have released Kwalify 0.7.0.
http://www.kuwata-lab.com/kwalify/

Kwalify is an integrated tool for YAML and JSON.
Kwalify contains parser, schema validator, and data binding tool.

This release has many enhancements and changes.
See
  http://kuwata-lab.com/kwalify/ruby/CHANGES.txt
for details.

From this release, Kwalify supports data binding.
If you specify class name in schema definition, Kwalify parses YAML/
JSON
and create instance object of that class instead of Hash object.
Data binding makes handling YAML easier.

Example:

* schema file (config.schema.yaml)
  --------------------
  type:  map
  class: Config
  mapping:
   "host": { type: str, required: true }
   "port": { type: int }
   "user": { type: str, required: true }
   "pass": { type: str, required: true }
  --------------------

* configuration file (config.yaml)
  --------------------
  host:  localhost
  user:  user1
  pass:  password1
  --------------------

* ruby program (ex1.rb)
  --------------------
  ## class definition
  require 'kwalify/util/hashlike'
  class Config
    include Kwalify::Util::HashLike  # defines [], []=, ...
    attr_accessor :host, :posrt, :user, :pass
    def initialize
      @port = 80
    end
  end
  ## create validator object
  require 'kwalify'
  schema = Kwalify::Yaml.load_file('config.schema.yaml')
  validator = Kwalify::Validator.new(schema)
  ## parse configuration file with data binding
  parser = Kwalify::Yaml::Parser.new(validator)
  parser.data_binding = true    # enable data binding
  config = parser.parse_file('config.yaml')
  p config  #=> #<Config:0x542590 @user="user1", @port=80,
            #        @pass="password1", @host="localhost">
  --------------------
