yes NB is really specific with its metadata description Le 10/9/16 à 10:03, Ben Coman a écrit :

In Pharo 5.0 I see deprecated classes stripped of all methods and variables defined in a package like...

Object subclass: #NBExternalStructure instanceVariableNames: '' classVariableNames: '' package: 'Deprecated50'

It was was useful having these remain to facilitate loading Pharo 4.0's TalkFFI for a first look at porting it to Pharo 5.0. Somewhat expectedly, the class initialization fails with... MessageNotUnderstood: CXIdxDeclInfoStruct class>>rebuildFieldAccessors

(since that method used to be in NBExternalStructure due to "NBExternalStructure subclass: #CXIdxDeclInfoStruct)

But it would be nicer to get a Deprecated message rather than a MNU, initially something simple like this...

Deprecated subclass: #NBExternalStructure

Deprecated class >> doesNotUnderstand: DeprecatedError signal.

but maybe later something like...

Deprecated class >> doesNotUnderstand: Transcript crShow: self deprecationNotes. DeprecatedError signal.

NBExternalStructure class >> deprecationNotes ^ 'Blah-d-blah. Use UFFIXxxxxx instead'.
