Description

Get wrapper for inverted comparisons.

Features

Wraps

  • #==
  • #===
  • #=~
  • #<=>

Usage

require 'vertere'

# An approaching to invert comparisons
num_chars = %w[0 1 9 10 11]
num_chars.grep(/0/)                  #=> ["0", "10"]
num_chars.grep(Veretere.invert(/0/)) #=> ["1", "9", "11"]

# Extend core classies
require 'vertere/core_ext'
num_chars.grep(/0/.for_!)            #=> ["1", "9", "11"]

# And more
num_chars.sort_by{|s|s.to_i.for_!}   #=> ["11", "10", "9", "1", "0"]

But I suggest Enumerable#grep_v from Ruby 2.3 :).

Requirements

Install
