Hi newsgroup,
I'm using the OCL console frequently and I am really missing some history function like the unix bash has, for instance.
So I coded one and I think it is really helpful especially when writing long expressions.
Instructions:
1. Apply the attached patch to the org.eclipse.emf.ocl.examples.interpreter project.
2. Run the OCL Console and explore the history with pageUp and pageDown :-)
I hope it might be helpful for some others, too!
Cheers
Patrick
