Write a gem description

The arr2hash gem provides a simple way to convert a 2D array into an array of hashes. The first row of the 2D array is used as the keys, and the subsequent rows are converted to values, creating an array of hashes. This is especially useful for converting structured data like CSV.

Arrangeable provides an organized and seamless way to sort your ActiveRecord objects by different attributes.

Implementation of 2D array

Provides users with methods for performing common math functions on arrays.

This gem defines some helpers to use array columns like assiciated models

Creates methods that accepts array of values and save them as bit mask extracted using specified source

An array buffer (a.k.a. byte array) implementation forRuby, implemented natively.

Enumerator abstraction layer that emulates certain array functionality (methods like empty?, slice, shift and more) by using a small cache and other tricks without loading all the data from the enumerator at the same time.

Add Array#===

This gem extends the Ruby class Array with a few useful methods. Just a bit of sugar.

This small extension to ruby's Array class provides two additional iterators, Array#each_with_floe and Array#each_with_index_floe, that simplify the reasonably-common need to specially handle "floe"--i.e., first, last, odd, even--when iterating through the elements of an array. It's particularly handy for generating CSS classes.

Array extension for frequency of values.

[1, 2, 4, 5] #~> [[1, 2], [2, 4], [4, 5]]

Convert array to hash according to your defined formatter

Array#include_all?, Array#include_any?, Array#include_array?, Array#array_index, Array#counts, and Array#duplicates methods missing from basic Ruby Array API. Compatible with Ruby, JRuby, Opal, and RubyMotion.
