Usage
Erray Custom Array Type
An Erray is a strict superset of the core Array functionality without modifying any builtin classes. It works great with normal Arrays!
require "enumerous/erray"
has_different_elements = Erray{1,2}.similar [2,3] #=> false
contains_same_elements = Erray{1,2}.similar [2,1] #=> true
extra, missing = Erray{1,2}.diff [2,3] #=> {[3],[1]}
index_of_first_difference = Erray{1,2}.diff_index [1,3] #=> 1
{1,2}.find_and_map {|element| element > 1 && element.to_s } #=> "2"
If you do not want Erray in the global namespace just pass -Dno_erray_alias
to the compiler and you can still access it from Enumerous::Erray
.
Optional Core Extension
require "enumerous/coreext"
has_different_elements = [1,2].similar [2,3] #=> false
contains_same_elements = [1,2].similar [2,1] #=> true
extra, missing = [1,2].diff [2,3] #=> {[3],[1]}
index_of_first_difference = [1,2].diff_index [1,3] #=> 1
[1,2].find_and_map {|element| element > 1 && element.to_s } #=> "2"
{a: 1, b: 2}.find_and_map {|key, value| value > 1 && "#{key}:#{value}" } #=> "b:2"
