Move Transcripter to ST80. Then check for presence of class named #Transcripter in Object>>#primitiveError: to determine whether to present and accept that option.

Good catch. It's been a while since I tried unloading/reloading MVC, but
I'm fairly sure that I never tried to do anything that would invoke it while I had MVC unloaded from the image. So I cannot say if it works in Morphic-only or not. Assuming that it is a problem, we should see how Juan handles it in Cuis (which has no MVC, and presumably does have a working emergency evaluator). I can definitely confirm that the emergency evaluator works in MVC, because I fell into it about a zillion times in the course of getting the debugger to work in MVC again ;-) Dave > I've not run into the emergency evaluator, but I wonder: Transcript > class >> #emergencyEvaluator calls Transcript >> #newInFrame:, which > calls #initInFrame: which checks for a class called Paragraph.

Or not, because moving the class is the wrong thing to do. Instead, the _right_ thing to do is to make a MorphicTranscripter and an St80Transcripter. The latter is just Transcripter with a new name, and the new Transcripter is an AppRegistry subclass, presumably in System-Applications. Morphic and ST80 then register their preferred Transcripter-protocol-fulfiller. > frank > >> frank >> >>> On Thu, Dec 12, 2013 at 1:33 PM, Frank Shearar <[hidden email]> >>> wrote: >>>> >>>> I've not run into the emergency evaluator, but I wonder: Transcript >>>> class >> #emergencyEvaluator calls Transcript >> #newInFrame:, which >>>> calls #initInFrame: which checks for a class called Paragraph.

Note to self: Touching a method that carries the initials 'di' is a fast path to public embarrassment. Not that I did not already know this... Dave |
