Truncating html with nokogiri, with/without Rails

Rails has a handy truncate helper (which is actually mostly a method added to String ), but it warns you it's not safe to use on html source, it'll cut off end tags and such.

What if you want an HTML safe one? There are a variety of suggested solutions you can google, none of which were quite robust/powerful enough for me.

So I started with my favorite, by Andrea Singh, using nokogiri.

But:

  • I modified it to not monkey-patch Nokogiri, but be a static method instead (sadly making already confusing code yet more confusing, but I didn't want to monkey patch nokogiri)
