Super simple conversion of hashes to plain Ruby objects. Great for consuming JSON API's.

Mash is an extended Hash that gives simple pseudo-object functionality that can be built from hashes and easily extended.

About Gibbler: Git-like hashes for Ruby objects

Extend ActiveRecord pluck to return hash instead of an array. Useful when plucking multiple columns.

A Ruby implementation of go-identicon by Damian Gryski RubyIdenticon creates an identicon, similar to those created by Github. A title and key are used by siphash to calculate a hash value that is then used to create a visual identicon representation. The identicon is made by creating a left hand side pixel representation of each bit in the hash value, this is then mirrored onto the right hand side to create an image that we see as a shape. The grid and square sizes can be varied to create identicons of differing size.

LruHash class, a Hash with a max size, controlled by a LRU mechanism

A XKCP based native (C) binding to SHA3 (FIPS 202) cryptographic hashing algorithm.

This gem add the "deep merge" feature to class Hash. It means that if you want to merge hashes that contains other hashes (and so on...), those sub-hashes will be merged as well. This is very handy, for example for merging data taken from YAML files.

A weird hash with special semantics for regex keys

Flattens deeply-nested hashes into sparse hashes

A RBTree is a sorted associative collection that is implemented with a Red-Black Tree. It maps keys to values like a Hash, but maintains its elements in ascending key order. The interface is the almost identical to that of Hash. This is a fork of the original gem that fixes various bugs on Ruby 2.3+.

Simple gem that allows you to run multiple ActiveRecord::Relation using hash. Perfect for APIs.

Load CSS and JS faster. Minifies, bundles, and optimizes CSS/JS assets ahead of time (e.g., on deploy), not at runtime. Loads popular third-party JS (like jQuery, YUI, and Dojo) from localhost in development, and auto-switches to Google's CDN in production. Lets you switch on LABjs mode to load more scripts in parallel. Can rewrite stylesheets to use CDN hosts (not just your web server) and cache-busting hashes for updated images.
