Consists of operations to manipulate arrays; the T of ETL for datasets that fit in-memory. Operations include adding/copying/removing/updating columns, adding/removing/updating rows and joining external tables.

List transitions found in an array

Trie-like, prefix-tree data structures. First, a prefix-tree based on Arrays, which differs from a traditional trie, which maps strings to values. Second, a more general prefix-tree data structure that works for any type of keys, provided those keys can be transformed to and from an array. Both of these data structures are implemented in terms of hashes.

Array validations for Rails (e.g. Postgres jsonb columns)

Query your arrays.

Easily visualize progress of any Ruby task. A drop in replacement for Array.each. Output uses different colors for successes/failured, allowing to easily check status of every task. Every line is trimmed/padded to match the terminal width. There is also a possiblity to change item name during processing. Transactions for ActiveRecord are also handled if required.

zip two arrays of comma separated strings

Array#zip_with inspired by Haskell's zipWith function.It takes either yields a zipped array to a block or reduces the zipped array with the given operator.

ActiveRecord serializer, avoid N+1

ActiveRecord has a lot of support for tables of similar values. But what about those one time only values, like site settings? This is what ARSettings is intended for. One line to add settings to your ActiveRecord classes. Two to non-ActiveRecord classes. And you can have settings that are not defined on any class as well.

Ruby Object Metadata Reflector

This gem takes an open approach and lets you decide how little or how much your project will be using the soft delete pattern. It can be configured on a per-model level to use whichever features are appropriate at the time. This makes it especially easy to introduce soft delete into existing projects.
