Hash helpers to map complex JSON to ruby objects. Handles associations and eager loading and collection injection

Useful method to fetch data from complex hashes and arrays

Provides a DSL for implementing classes which can then be consumed to create pre-defined hashes.

Diffs two hashes

Hash with dynamic setters and getters

Struct with hash as initialization argument, to avoid dependency on positional arguments

Hashematics is a configuration-based object graphing tool which can turn a flat, single dimensional dataset into a structure of deeply nested objects.

Provides an assertion to test for hashes equality.

Create an SHA256 fingerprint of a hash or array.

A refinement which includes a method for flattening nested Hash to one level depth with keys joined with a dot. Also includes a method for reverse operation.

Hashie2 + ActiveModel 3, offering declared properties, validations, JSON serialization/deserialization

Make hash-based object initialization easy! Provides hash_make method that can consider parameter name, type, default value, validation, and requiredd/not, according to the specification provided. Also, by default assigns by default to instance variable of same name as parameter.

Converts nested Hashes into a nested struct

This library offers general purpose higher-level data structures that focus on Hash manipulation.

A Ruby library of functions to access and manipulate hash data structures.

hash-param allows you to declare, validate, and transform endpoint parameters as you would in frameworks like ActiveModel or DataMapper without the overhead. This gem is a variation of the sinatra-param gem https://github.com/mattt/sinatra-param modified to be more generic and with some additional features

A small collection of useful hash extensions

New Hash methods from 2.4/2.5 and well as Hash convenience methods from the future

HashSerializers.

HashStore store RubyHash into Redis as JSON. Automatically add redis commands(GET,SET,DEL,EXITS) methods to your class. HashStore was designed to work with ActiveRecord, but also work with Non-ActiveRecord Class.
