Hello,
I would like to know if in atl is possible to work with files, to be able
to open, read and write in files from Atl.
thank you very much
greetings

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].
