Hi,
So the answer is no. But you can build an annotation model instead of
describing your design decisions in a raw text file. Annotation models
are weaving models. You can have a short description of annotation
models here: http://www.eclipse.org/gmt/amw/usecases/annotation/
You can also ask questions on the AMW newsgroup
(news://eclipse.modeling.gmt.amw) for more information about how to use
this annotation model in your transformation.
Best regards,
Mikael

Hello,
I would argue that the answer is actually yes. However, you need to
follow the model engineering principles. ATL is not a GPL (General
Purpose Language) like Java, but a model transformation DSL (Domain
Specific Language) like SQL for database queries.
Following the model engineering principles here means that you have to
consider your additional file as a model. The following Howto entry
gives more information on how to do this:
http://wiki.eclipse.org/index.php/ATL_Howtos#How_do_I_use_ex tern_parameters_in_ATL_transformations.3F
This Howto entry uses an XML file to provide additional arguments to the
transformation. However, if you prefer a textual syntax, you may use TCS
instead:
http://wiki.eclipse.org/index.php/TCS
With TCS, you may even be able to use the very same format you were
already trying to use.
Finally, I must say that it is even better (because closest to the model
engineering principles) to define this additional model as a weaving
model, as Mikaël suggested. Furthermore, IIRC Mikaël has shown that it
is possible to use TCS to define such an annotation model that is also a
weaving model.

Frédéric Jouault
P.S.: Please, remember to prefix the subjects of your ATL-related posts
on this newsgroup with [ATL].
