HashPath

Provides a simple interface to access hash paths.

The gem was written to help with specs, so use in production code will have an unknown performance hit.

Installation

Add this line to your application's Gemfile:

gem 'hash_path'

And then execute:

$ bundle

Or install it yourself as:

$ gem install hash_path

Usage

Given the hash { 'foo' => { 'bar' => { 'baz' => 'hai' } } }

# Nil versions
my_hash.at_path("foo.bar.baz")   #=> 'hai'
my_hash.at_path("foo.bar.barry") #=> nil
my_hash.at_path("not_a_key")     #=> nil

# Or the raise version
my_hash.at_path!("foo.bar.baz")   #=> 'hai'
my_hash.at_path!("foo.bar.barry") #=> raises
my_hash.at_path!("not_a_key")     #=> raises
