Sparsify

Convert a deeply-nested hash into a shallow sparse hash. Useful for tools that either can't handle deeply-nested hashes or that allow partial updates via sparse hashes.

This gem is our internal implementation of our [Sparisfy Challenge][].

Usage

require 'sparsify'

Sparsify({'foo' => { 'bar' => {'baz' => 'bingo'}}})
#=> {'foo.bar.baz' => 'bingo'}

Unsparsify({'foo.bar.baz' => 'bingo'})
#=> {'foo' => { 'bar' => {'baz' => 'bingo'}}}

Advanced Usage

Custom Separator

require 'sparsify'

Sparsify({'foo' => { 'bar.bar' => {'baz' => 'bingo'}}}, separator: '|')
#=> {'foo|bar.bar|baz' => 'bingo'}

Unsparsify({'foo|bar.bar|baz' => 'bingo'}, separator: '|')
#=> {'foo' => { 'bar.bar' => {'baz' => 'bingo'}}}

Sparse Arrays

require 'sparsify'

Sparsify({'foo' => ['bar','baz','buz']}, sparse_array: true)
#=> {'foo.0'=>'bar','foo.1'=>'baz','foo.2'=>'buz'}

Unsparsify({'foo.0'=>'bar','foo.1'=>'baz','foo.2'=>'buz'}, sparse_array: true)
#=> {'foo' => ['bar','baz','buz']}
