Fileswap script to download files in batch. This javascript code will iterate over an URL list to download each file in it, with an interval of 15 seconds between each link (I consider this a safe interval, as a smaller one might open too many pages at the same time, and eventually the browser won't be able to respond to the new requests, breaki…

Rails Prawn: How to print different data per page inside a dynamic repeater

The problem with repeaters

How does Prawn's repeaters work?

Prawn is an amazingly configurable and flexible tool for PDF generation. It allows you to create boring financial style PDFs that can almost mimic a (static) Excel spreadsheet, and can also create a convincing party invitation letter.

One of Prawn's many tools to allow this kind of flexibility is the Repeater. It allows you to define a section of your PDF, and reuse it over and over, essentially stamping it on every page (or just on odd pages, or on the first 10 pages, etc, you can also configure that).

Let's create a simple PDF document as an example:
