== DESCRIPTION:

Parses a hash string of the format '{ :a => "something" }' into an actual ruby hash object { a: "something" }. This is useful when you by mistake serialize hashes and save it in database column or a text file and you want to convert them back to hashes without the security issues of executing eval(hash_string).

By default only following classes are allowed to be deserialized:

• TrueClass
• FalseClass
• NilClass
• Numeric
• String
• Array
• Hash

A HashParser::BadHash exception is thrown if unserializable values are present.

== FEATURES/PROBLEMS:

• Any potential security issues?

== INSTALL:

• Add to Gemfile: gem 'hash_parser'

== DEVELOPERS:

require 'hash_parser'

# This successfully parses the hash
a = "{ :key_a => { :key_1a => 'value_1a', :key_2a => 'value_2a' },
       :key_b => { :key_1b => 'value_1b' } }"
p HashParser.new.safe_load(a)

# This throws a HashParser::BadHash exception
a = "{ :key_a => system('ls') }"
p HashParser.new.safe_load(a)

== TODO:

• Allow objects of certain types to be deserialized
