https://rubygems.org/gems/rgn

RGN short for Random generated name, is a ruby gem to allows users to automate random strings in their ruby apps.

Add this line to your application's Gemfile:

gem 'rgn'

And then execute:

$ bundle install

Or install it yourself as:

$ gem install rgn

If you're just developing a non-rails app in ruby, then just import the following code inside your file: require 'rgn'

• Input require 'rgn' at the beginning of the ruby file.
• Input include Rgn after the require statement.
• Next, declare a variable to contain generator function. For example, randomStr = generateName
  Then enter: puts #{randomStr} or puts randomStr to generate random string.
