I'm writing an Interface Control Document (ICD) that contains dynamic data queried from relation databases and extracted from Magic Draw SysML/UML models. The java "backend" to obtain/generate this information already exists. All the data I need to generate the document is stored in java objects/collections.

Currently, the ICD is generated with Velocity scripts in a Microsoft word document...which is difficult to work with. I would like to be able to generate the document with Latex from a more programming friendly context. Is there a library or .jar file to import which enables programmers to make Latex calls to create paragraphs, sections, tables, etc. with dynamic data from a java context?

Thank you

  • I would guess the usual way is to handle the whole document as writing text from Java producing a latex document that you process to get the final pdf rather than processing individual paragraphs as separate latex calls. But perhaps that doesn't work for your use case? – David Carlisle Sep 27 '21 at 14:49
  • No idea of Java, but for dynamic LaTeX reports knitr could be a goos solution if your databases can be exported to some manageable for R language (CSV, Excel, SPSS, ODBC...) and you have some experience with R or python. If this is not a potion for you check if datatool LaTeX package is what you are looking for. – Fran Sep 27 '21 at 17:32
  • Maybe a templating engine like the Java LaTeX Report (JLR) library (which is based on the Velocity Template Language (VTL) from Apache) could be useful here. – Marijn Sep 28 '21 at 14:57
  • Thanks for the feedback. Fran, I like your suggestion but the “long pole in the tent” is extracting the data from the sysml and uml models from magic draw. That’s in Java - not much I can do - although I could save as csv or something…. David, that’s where I run into a problem. It’s a technical document with sections numbers like 3.4.2.7.1. Trying to handle the whole thing at once (instead of in sections) is the challenge. I guess I could create some sort of object oriented structures in Java representing the latex components/sections (chapter, table, figure,etc), then after processing the dyn – Phil Sep 28 '21 at 13:44
