First thought was to re-implement stuff in Jython or Groovy, because these are dynamic languages. But then I've decided to go with plain Java to avoid troubles in a future.
In this project, will no more ReportLab's RML markup for documents for a number of reasons. In short: I want markup to be small, cute, flexible and extendable, unlike RML. I had implemented a reporting middle-ware in Aozora Bank and now I see why RML is quite clunky idea.
Now, the project is in very early stage, no any RPC server yet and data integration. But it already can produce something: rich text paragraphs, coloring, fancy tables, clickable table of contents, insert images from URL or file etc.
Today I had implemented Japanese QRCode barcode. It is amazing data encoding, which is damage-resistant and can contain lots of data on quite small print-out size. We have plenty of them everywhere and we need them on a paper too. I also working on mobile application, which scans the code from a camera or any image and decodes it back to text.
