Patternify

This ruby gem provides a DSL to describe patterns of regular expressions in a more human readable way.

pattern = Patternify::Pattern do
  one_or_many do
    any_char
  end
  
  string "@"
  
  one_or_many do
    negate do
      string "."
    end
  end
  
  string "."
  
  either do
    string "com"
  end.or do
    string "org"
  end.or do
    string "net"
  end
end

pattern.to_s

# => .+@[^\.]+.(com|org|net)

pattern.to_regexp.match?("[email protected]")

# => true

Note: I started this gem for fun and it is highly incomplete and lacks validations and documentation. Pull requests are welcome.
