Usage

Simply replace things and thing with whatever large object you're iterating over and put your iteration code in place of the code comment.

Explanation

In ruby you can append with_index and an index variable to your enumerators and it will give you an iterator counter (i). Using this we calculate a progress precentage:

(i.to_f / things.length * 100).to_i

The regex patterns in this gist are intended to match any URLs,
including "mailto:[email protected]", "x-whatever://foo", etc. For a
pattern that attempts only to match web URLs (http, https), see:
