Hi I continued to code a little tool based on code of Alain to detect deadcode, so far I'm too sick to have clear idea why it freezes on Morph. However it works on ClockMorph and IconicButton. If you want to have fun save your image before MCHttpRepository location: 'http://www.squeaksource.com/MetaF' This package got inspired heavily by code given by Alain Plantec. It was further improved by S. Ducasse and S. Denier who got great fun in designing it. The basic principle is the following one: rename all methods of a class: XXX -> NOTSENTXXX. but before install #doesNotUnderstand: and #recompileNotSent:, so that, for a not understood message named YYY, if NOTSENTYYY exists, then, NOTSENTYYY is dynamically renamed YYY and then, message is resent. Deals also with superclass methods that were hidden (and could be accessible due to the previous strategy), by recompiling them locally with the default behavior to recompile themselves into the NOTSEND associated one when executed. 1 March 2009 Known Issues: ---------------- - freezes when applied on Morph Stef
