First success with modeling the message formats for the Siemens S7 Protocol with Daffodil

Hi all,

I just wanted to report that after finishing a first version of my S7 dfdl, I pretty quickly finished the 2 underlying protocols too.

https://github.com/apache/incubator-plc4x/tree/develop/src/main/dfdl

Next I will probably start with using daffodil for parsing/serializing test-data for easy human inspection
(the XML or JSON files will be a lot easier to maintain as the PCAPNG files).

Maybe I’ll even whip up a version of the S7 protocol based entirely on daffodil so we can do a performance measurement.
However I expect to require more CPU time and memory using this path …

As soon as I’m a little more familiar with it, I guess we could start the discussion on some code-generation.

I don't know that it has been done before, but these are standard junit tests, just implemented in scala (usually), and so things that run Junit 4 tests detected in a src/test/scala or src/test/java directory will find these and run them.

Thanks for both your responses :-)

As we are building with Java and Maven, I'll probably stick more to the maven defaults and project setup.
I bet there is a way to run all of these tests in Maven surefire. Has this been done before?

    It asks a couple questions about your format, then generates a project

    can then run:

      sbt test

    to run the tests defined in the scala/tdml file. Information about the

Very nice schema Christofer.


I recommend adding tests in TDML so as to exercise these in your ordinary unit test/regression using Daffodil.


This article:


https://daffodil.apache.org/dfdl-layout/


explains the way we do this for sbt. Minor adaptations needed for maven I'm sure.
