RGhost and RGhost-Rails
I really like the report resulted from an EPS Template. RGhost do this with perfection - lines and elements very good defined on the document. Quick, precise and light - yeah - do all the job without a lot of processing and memory consumption.
I started on a project with RGhost, but some issues with my environment after installing the last version of Xcode or after removing the MacPorts made me change the library - unfortunatelly - because I really enjoyed in using it and because I didn’t find other so cool like this one.
Ok, it isn’t so easy to draw each item on your position - we are talking about PDF reports on web - with Rails - without that bloated IDEs and without report design tools. :P
Prawn and Prawnto
Simplicity and no dependencies. There are a lot of missing features - but it works. There are some examples of Prawn use on the Prawnto homepage.
No EPS support yet - but it does the work fine. I enjoyed the result but there are some issues with the cpu processment from these gems - took a lot of time to generate the report here - maybe this impression was caused by the RGhost - since was my first attempt with Ruby and PDF reports.
So - both tools do the job - if you want EPS support and a ghostscript dependency isn’t a problem for you - RGhost is the perfect tool. But if you need a pure implementation and no advanced formatting text features - Prawn works fine too.
