Re: [Pharo-users] String operations

by Tudor Girba

In the Moose configuration, there is a CollectionExtensions that allows you to do this: 'BormParticipant' removePrefix: 'Borm' "-> 'Participant'". 'BormParticipant' removeSuffix: 'Participant' "-> 'Borm'" For Pharo 5, we should move these extensions to Pharo.

Sadly not, because with that experiment there is a DNU when opening the editor which is quite strange.
