This gem does not handle "complex" regular expressions correctly. For example:

/[a-z]/.gen # => "[a-z]"
/(?:test)/.gen # => NoMethodError: undefined method `first' for nil:NilClass
/\n/.gen # => "n"

It also does not use "real" regex for various examples, but instead invents its own syntax - for example:

 /[:sentence:]/.gen # => "Nonhearer demetricize toppiece....."

While this gem might be perfectly good for your needs, if you're looking for a more "complete" regexp parser, check out my gem: https://github.com/tom-lord/regexp-examples
