Re: [henshin-user] How to best debug an inexectuable transformation?

Hi Daniel,

Thanks for the quick response!

        This means you're working with UML profiles?
        This makes things a bit complicated indeed, including the setup of
the 
environment.

No, indeed the similarity is that I can execute the rule without problems,
using the GUI, but fail to have the transformation run using the Java API.

OK, great - I'll try this out!

Best,
Roland

Hi Roland,

	Dear Henshin developers,

	I am new to using Henshin and still struggeling to get a simple
	transformation (in fact: a "match-only rule") running.
	I suspect that it could be a simliar issue as reported in
	https://dev.eclipse.org/mhonarc/lists/henshin-user/msg00036.html .

This means you're working with UML profiles? This makes things a bit
complicated indeed, including the setup of the environment.




	Therefore, I would like to debug the transformation process
(Java-code level
	is fine!).

	Is there a simple way to install the source code such that I can
debug the
	transformation process?

Coincidentally, we support such a simple way since 2 weeks: The
nightly-build update site now has a "source" feature. See
http://download.eclipse.org/modeling/emft/henshin/updates/nightly/




	Is there another way of executing the transformation that gives me,
e.g., a
	status report/a partial match/...?

For the inter-rule level, there is the concept of ApplicationMonitor - see
https://wiki.eclipse.org/Henshin_Interpreter

Unfortunately, for the intra-rule level, which seems to be the scope here,
I can't point you to anything at the moment. Debugging Henshin is actually
an active research area, and we hope to make some progress on this in the
future (CC'ing Matthias Tichy, who's working on that.)

Best regards,
Daniel






	Best,
	Roland
