Append to target file in EGX/EGL [message #1760589]

I'm trying to create a transformation just like in this example: https://www.eclipse.org/epsilon/examples/index.php?example=org.eclipse.epsilon.examples.egl.library

The way it is now, the target files are overwritten every time a rule is executed. Is there a way to append to the target files? Where do I specify this?
Thanks in advance.

Hi Christina,

I think you need to check the "Append to file" option on the Run Configurations window of your template.

Kind regards,
Alireza

Hi Christina,

If you're using EGX, you can achieve this as follows e.g.

rule Foo transform f : Foo {
  template : "foo.egl"
  target : f.name + ".txt"
  merge : true
}

Cheers,
Dimitris

Thank you very much, seems like this is exactly what I was looking for! However, I just tried it out and it didn't do the trick, only the last transformation of my "Foo" is in the file Sad

Hi Christina,

You're right - my bad. Could you please update to the latest interim version from the update site below when the current CI build finishes [1] and try again but with "append" instead of "merge"?

Cheers,
