Interesting, so this would be the one I'd like to see (because I implemented with AST transforms). Would you have a link to his work? Mine is on github, and the version I did at UBO was on the VisualWorks AST. Thierry > Marcus

I made the mistake of doing some stuff (after links, for example) directly in the IR level, that did not work. Now this is fixed for all but the links for Sequences (to be done later). Steven did a version that is based on AST transformation only, we will explore that direction further in the future. Marcus

Spec + Graphics?

by Dan Wilczak

Hi, I'm interested in using Pharo to create a simulation with animated 2-D graphical output. The user can start/stop the simulation, change display modes, zoom in and out, and change various settings during operation. That means that, in addition to a graphical pane, I need a menu bar or maybe a panel of buttons which create popup windows. Can I use Spec for such a thing? I don't see any way to embed a graphical pane in a Spec application. The Spec examples don't include one either. Secondly, if it is possible to use Spec, what would you recommend for the graphics? Bloc and Sparta look very appealing but aren't officially released yet. The long-term futures of the other options aren't clear to me.

Hi Norbert! We don't have yet implemented any nor all combinations. I will add it to the list of things to do for next release. Looks like a simple and useful thing to have.
