Hi,

I would know if there is a way to generate C++ code using Papyrus Software Designer in headless mode (without Eclipse UI). If yes, what would be a typical command line to achieve that?

Regards.
Yoann.

Hi

In principle it's just Java code so of course you can do it, just use a debugger to see where the good code starts and invoke the same code yourself.

But, I recall that to get EMF to GenModel standalone, I had to override a method that assumed a running platform. This has now been fixed. Subsequently I had to get JDT to revert a regression that again imposed an unjustified running platform assumption.

So yes, you can almost certainly do it, but may have to work hard and contribute back your solutions to the developers.

Or .. someone who's already done it can just yell you how.

Hi Ed,

Thanks for your reply and advice.

I already managed to generate code by calling Java code into the Eclipse application. I have to watch in detail how to avoid the UI prompts during the creation of the code project. What I would do initially was to call a command line from a terminal similarly to what can be done to create or build a project in headless mode but it is probably not available today.

Example of command line to build a project :

/eclipse -nosplash -data /app/ws -application org.eclipse.cdt.managedbuilder.core.headlessbuild -import $PROJECT_NAME -build $PROJECT_NAME

I'll try the Java way.

Regards.
Yoann.

Hi Yoann,

while the generator tests are not running in headless mode, they also face the problem that they need to avoid the UI dialog for project creation. The workaround currently in place in the test code is to create the projects in advance (see plugin oep.designer.transformation.languages.cpp.tests). The created project is not a specific CDT project though, as this was not relevant for the test.
