Hello,

is it possible to write to the Eclipse console from a black box library that I'm importing in qvt? System.out.writeln and the usual ConsolePlugin method don't work.

Hi,
I'm not sure whether you can do this directly, but you could write a query that prints something in the terminal (by using a string Parameter). I'll investigate this further as I would like to know how to do this myself.

Thank you for your response.

I'm not sure what you mean, though. Obviously I can write a query in qvt that uses log to print to the console, but I wouldn't be able to call that query from the black box, would I?

Hi Phaz ,

Unfortunately there's no access to console of Eclipse instance being
used from the QVTo black-box library.

Would you mind to raise a bugzilla?
https://bugs.eclipse.org/bugs/enter_bug.cgi?product=M2M&
component=QVT_OML-Engine

Possible we can add addition annotation like
@Operation(withLog=true)
so addition parameter of org.eclipse.m2m.qvt.oml.util.Log class would be
passed to library method.

Or may be whole QVTo evaluation context could be more useful like
@Operation(withQvtoContext=true)
so addition parameter of
org.eclipse.m2m.internal.qvt.oml.library.IContext class would be passed
to library method.

Regards,
Sergey
