Underscore.strings.httpize.js

What is Underscore.strings.httpize.js?

This little script is an extension for Underscore.strings.js, and hence Underscore.js, a great Javascript utility library.

It makes use of the startsWith function included with Underscore.strings, allow you to add http:// to the front of strings where doing so is desirable. Before it does this, it uses startsWith to check if http:// is already present. Once it has done it (or not as the case may be!), it returns the result.

How do I use it?

A full usage example is included in example.html. In short, you need to include underscore.js, underscore.strings.js and underscore.strings.httpize.js (preferably in that order) and then run _.httpize(string_tohttpize). Or you can use the alternative syntax of (string_to_httpize).httpize().

Future updates...

I created a version 1.1 with support for adding https:// to the start of URLs, but decided not to release it as I couldn't decide on a behaviour which I thought was good.

Is this a feature that anyone would be interested in? If so, would you want to force a URL which is originally http:// to be https://, or would you leave it with the original prefix? How would you make such a feature behave?

It would be great if anyone felt like making their own version with such a feature. If you're up for it, fork the repository, update it and send me a pull request and I'll be sure to take a look :)
