copied!<p>Disclaimer: I'm a regular committer to the prawn project.</p> <p>Prawn isn't built on top of PDF::Writer - it's a replacement written from the ground up that avoids many of the limitations. I'd advise against PDF::Writer. It's old, difficult to use and doesn't support Unicode text.</p> <p>Depending on the kind of document you need to generate, you have a few options:</p> <p><a href="http://github.com/bruce/rtex/tree/master" rel="nofollow noreferrer">RTex</a> is a rails plugin that uses latex to generate PDF output. If you need to generate a formatted document with lots of text and you're happy with the (huge) latex dependency, it's a nice solution.</p> <p>If you like the idea of a HTML->PDF conversion (like HTMLdoc but you know... good), you could try <a href="http://www.princexml.com/" rel="nofollow noreferrer">PrinceXML</a>. There's a free version, but it watermarks the output. The licensed version is a few thousand dollars. The output is great, thanks to useful CSS support. There is at least 1 plugin that helps you integrate Prince with Rails - <a href="http://github.com/mbleigh/princely/tree/master" rel="nofollow noreferrer">princely</a>.</p> <p>For generating the output with Ruby syntax, Prawn is your best option. Manually building the pages of your output gives you plenty of fine grained control, but you <em>can</em> get bogged down in co-ordinate maths. It's also not capable of at least one of the features you require - nested tables.</p> <p>Which one works for you really depends on the style of document you need to generate.</p>
