A [human readable API](https://bramtayl.github.io/RegularExpressions.jl/dev/) for regular expressions. Still missing a couple of trickier REGEX features (recursion, conditionals, call-backs), mostly because I don’t understand them (halp!).

I think I’ve been using regex too long - your example looks _less_ readable to me than `^(http(s?):\/\/)?(www\.)+[a-zA-Z0-9\.\-\_]+(\.[a-zA-Z]{2,3})+(\/[a-zA-Z0-9\_\-\s\.\/\?\%\#\&\=]*)?$`

What is wrong with me?!? 😆

But seriously, this looks pretty cool!

I find the `rexegg` site helpful

I believe the dev version now supports all features of PCRE2

Nice project! Another website I found very helpful is [regex101.com](https://regex101.com/). What I like about it is the syntax highlighting and the interactive testing tools and information they have.

Would be cool if there was a display output in Julia for `regex` with colored syntax highlighting.

Yes, I use [regex101.com](http://regex101.com) all the time to test that my regex’s actually work and to figure out the captures.
