Make difficult regular expressions easy! Ruby port of the awesome VerbalExpressions repo - https://github.com/jehna/VerbalExpressions
# Create an example of how to test for correctly formed URLs tester = VerEx.new do start_of_line find 'http' maybe 's' find '://' maybe 'www.' anything_but ' ' end_of_line end # Create an example URL test_url = "https://www.google.com" # Use it just like a regular Ruby regex: puts 'Hooray! It works!' if tester.match(test_url) puts 'This works too!' if tester =~ test_url # Print the generated regex: puts tester.source # => /^(http)(s)?(\:\/\/)(www\.)?([^\ ]*)$/
This is an interesting idea (and possibly more maintainable than standard regular expressions).
