Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.

$ guard #  require './lib/cracklib_reloaded'

Run script

CAUTION: Using password as a script argument may not be safe

$ ruby init.rb 'admin123'
Equivalent of ActiveModel::Errors#messages
{:password=>["it is based on a dictionary word"]}
[[:password, ["it is based on a dictionary word"]]]
