So, how is the state of Opal? My old code insert nodes in the compiler generated ast, but the way the nodes are build in the pharo compiler makes it more difficult. If there is a reasonable chance the code generation is correct, I can try. For now, I've just discovered there is a dependency on petit parser. I'll break my 1.4 image soon :-) Thierry -- Thierry Goubier CEA list Laboratoire des Fondations des SystÃ¨mes Temps RÃ©el EmbarquÃ©s 91191 Gif sur Yvette Cedex France Phone/Fax: +33 (0) 1 69 08 32 92 / 83 95

But try this code, and you will get my point: | m | m := Morph new. m openInWorld. m color: Color red. 1 to: 300 do: [:x | m extent: x@300. (Delay forMilliseconds: 10) wait. ]. m delete. I want to see the animation of the growing morph. Instead I get nothing. To get the animation, you have to enclose the loop in a forked process, but it is inelegant: | m | m := Morph new. m openInWorld. m color: Color red. [1 to: 300 do: [:x | m extent: x@300. (Delay forMilliseconds: 10) wait. ]. m delete] fork.
