CompactBlank

Adds compact_blank and compact_blank! to Array and Hash

Use activesupport's #compact_blank instead of compact_blank

see. #11

Add this line to your application's Gemfile:

gem 'compact_blank'

And then execute:

$ bundle

Or install it yourself as:

$ gem install compact_blank

using CompactBlank

array = ["a", nil, "b", ""]

array.compact
#=> ["a", "b", ""]

array.compact_blank
#=> ["a", "b"]

array.compact_blank!
#=> ["a", "b"]
array
#=> ["a", "b"]

using CompactBlank

hash = { a: "1", b: nil, c: "3", d: "" }

# NOTE: Hash#compact is feature of activesupport
hash.compact
#=> {:a=>"1", :c=>"3", :d=>""}

hash.compact_blank
#=> {:a=>"1", :c=>"3"}

hash.compact_blank!
#=> {:a=>"1", :c=>"3"}
hash
#=> {:a=>"1", :c=>"3"}
