usually something like if f.array_type is not None works

maybe find a better name, it is not a .h file

as a side note, where and how are you using this OpenDDS ? |

I have to interface paparazzi with a system that uses OpenDDS - imagine a mission computer . The details are still in the working, but I wanted to share what I have so far. |
|
Without looking at the details, this is not really OpenDDS specific, right? Also is it a spec on the DDS or RTPS (RealTimePublishSubscribe) level? |
|
Good point - any system that understands IDL format can in theory use it. From FAQ:
Does that answer your question? |

For bookkeeping purposes, I am describing here what needs to happen to make this actually useful. Generated code

Application codeIn order to make a useful application (such as OpenDDs - Pprzlink translator), the following is needed (for a simple "link" application):

Integrating DDS would be welcomed, maybe I shoud add it to the "list" ;) |
OpenDDS is an open source implementation of Publisher-Subscriber communication service (more info here http://opendds.org/).
This PR adds an option to generate OpenDDS compatible IDL format from messages.xml.
More information and an example of OpenDDS<-->Pprzlink communication will follow, but I am seeking some early feedback on the Python implementation. Plus this works as is.
