Hello,
Some time ago, I made a RossalModel for Spec and it works in pharo 3.0. It is basically a spec-model wrapper for a Morph.
I am no sure if it still works with the current version of Roassal. But you can found it in the attached file.
It also contains two usage examples, you can try executing these instructions in a workspace.
1) RoassalSamples new openWithSpec. "a list of Roassal visualisations"
2) RoassalEasel new openWithSpec. "a roassal visualisation editor, please use cmd+s when finish the Roassal script."
- For instance. you can try writting "view nodes: (1 to:10)." and after cmd+s.
Regards,
Juampi
