Auto-recognize links?

Ruby
1

In PHP I’ve got a few functions that will turn data into links based on
if it recognizes “http://”, “www.” etc etc.

How can I do this with Ruby?

For instance, in a forums setting if a user posted a link to something
like http://example.com

It’d basically turn it into a clickable link:
<a
href="http://example.com">http://example.com</a>

I think everything you’d need to do to validate and produce links should
be in the core URI class: http://www.ruby-doc.org/core/classes/URI.html

Interesting, did not know that. Seems bad though:
URI.extract(“Visit Google”) # => [“Google”]

You could borrow code from Rails’ auto_link() which handles that kind
of stuff better:
