[ATL] User interaction during transformation [message #25827]

Hi,

sometimes a transformation cannot be fully specified, because additional
information is needed from the modeler. Therefore it is necessary to ask
the modeler during transformation about the missing information.

Is this scenario covered by any mechanism in ATL or are there any
concepts to add it in the future?

Thanks in advance.

Hi Markus,

I don't know if it is possible to change some parameters during the
transformation execution.

But, i have implemented a solution with a input Xml parameters file.
I think that this file can be easily generated by your application.

You can this example in the ATL Wiki in the following page:
http://wiki.eclipse.org/index.php/ATL_Howtos#How_do_I_use_ex tern_parameters_in_ATL_transformations.3F

I hope that helps you

Best Regards,

Albin.

Using ATL, it is voluntarily not possible to provide some additional
information during the effective execution of a transformation.

The recommended (and usual) practice in ATL is to break up your overall
transformation in several steps (i.e. several intermediate
transformations). By this way and by using XML models as additional
inputs of your transformations (as explained by Albin), you can allow
the modeler to intervene at some well-determined moments during the
whole transformation chain.
