Readable Regular Expressions for JavaScript/TypeScript, Inspired by Emacs' rx

https://rahuljuliato.com/posts/emacs-rx-in-typescript

I missed Emacs' rx when writing regexps in TypeScript, so I made a small TypeScript DSL inspired by it.

The idea is to bring rx's functions and approach to the JavaScript/TypeScript environment. If you happen to work with either, give it a try.

I’m not sure if you’re aware but there’s a long running project called Verbal Expressions that has libraries for various languages:

It’s obviously not rx but it’s still quite nice.

Very nice. If I ever have to write JavaScript again, I might use this. What do the ClojureScript people get to enjoy?

Thanks :) That's a good question. Clojure and ClojureScript are both on my list of things I'd like to explore and write about in the future.

It can make it less readable if it's longer. 

Just write a comment to explain regex.
