Transform Concept into other concept before TextGen

Hello,

could I ask you to explain the desired transformation, please? What should be transformed into what? Maybe an example could help.

Hi,
I put the model in the attachement.

In fact, I want to transform the Exception concept in a Decision Concept.
(The user manipulate the concept of exception. However, in the target code, this is transform in a specific decision in wich I define "manually" all the properties.

To make a model-to-text transformation I use TextGen.
In the generator, I try to use the "weaving rule". But I don't understand what must return the "context".
Currently I make a pre-script. But I'm not sure that is the good solution.

For exemple :
we have this :

//Exception
when conditions
do
   throw error 2
end

//And the generator transform this exception in the decision : 
when conditons
do
   ... some actions that I define "manually"
end

And then we give this code to TextGen.

Thank you very much.


Edit : model :

I guess you need to insert a link to the attached file into the comment so as we could get it. At least I cannot see it anywhere around :)

Oh sorry.
Fixed it, thanks

I may have misunderstood, but to mer this looks like a use-case for the COPY_SRC macro that would replace Exceptions with Decisions.

BTW, have you tried the MPS generator tutorial? - https://confluence.jetbrains.com/display/MPSD31/Generator+Demos
This should give you a solid introduction into the generator capabilities.
