Regex is a very powerful tool, learn it well and you will be able to solve many problems with that. Best wishes.

never seen something like this before, any resources where i can learn more about advance regex like this? thank you

Guys, look at my solution, it support "http://subdomain.domain.com" :)

Yup missed it! Seems the test didn't catch me. Will update it.

it also doesn't support "http://subdomain.domain.com". my solution doesn't either, but I was trying to write the minimal amount to pass the tests ;) because lazy

Is that a requirement?

this solution only supports 'http/https' protocols, and doesn't support other (ftp://, git:// ...)

I agree

Beautifully well written! and yes readability to the best!!! :)

Not until your Ruby is valid. Then, depending on the tests the kata submitter set, it'll give a different message.

Not sure using rescue for logic branching is recommended.

This uses two loops, it would be better to do the filtering inside the reduce/inject block.

any? is a better pattern than all?
