I you reimplement it you’ll develop something completely different. If the prior code would be good there would be no point in redoing it. And there is no point when redoing to do the same as before. You redo and you have the freedom to design something new while you skip all the wisdom/experience that has made its way into the old code. If you make it good the new thing will be an improvement to the old. Mostly you will end up having a new software with different problems but the same amount :) Norbert > >> >> >> On Wed, Jun 11, 2014 at 10:25 PM, François Stephany >> <[email protected]> wrote: >> \o/ >> >> >> On Wed, Jun 11, 2014 at 4:23 PM, Camille Teruel <[email protected]> >> wrote: >> >> On 11 juin 2014, at 15:31, François Stephany <[email protected]> >> wrote: >> >>> What is bloc ? >>> I've searched in the pharo-dev list but couldn't find it :/ >> >> A Morphic clean/revamp lead by Alain and Stef. >> >>> >>> On Wed, Jun 11, 2014 at 2:26 PM, stepharo <[email protected]> wrote: >>> looks so exciting... >>> >>> From: Alain Plantec <[email protected]> >>> Subject: Bloc news >>> Date: 11 Jun 2014 14:10:29 GMT+2 >>> To: Stéphane Ducasse <[email protected]> >>> Cc: Alain Plantec <[email protected]> >>> >>> Name: Bloc-Core-AlainPlantec.15 >>> Author: AlainPlantec >>> Time: 11 June 2014, 2:07:16.813171 pm >>> UUID: d58ae82e-b5dd-41d9-bc31-a48c3e9e5cf1 >>> Ancestors: Bloc-Core-AlainPlantec.14 >>> >>> - BlMorphs manage their submorphs with local coordinate. >>> - Drawing and drag&drop has been adapted to local coordinate >>> - Consequence: TransformationMorph should not be useful anymore because >>> each morph has its own transform (not only TransformationMorph).
