Hi all, i just wanted to re post the fix underscore code Lukas posted a while ago. I've just imported Connectors package into pharo, (i'm trying to get a minimal version working ), and stumbled upon the problem of the underscores.. but now thanks to SmallInt rules it was easy and fast to overcome this problem! Thanks!!!! Fernando pd: From previous mail from lukas. 1. Load the code: Gofer new squeaksource: 'rb'; package: 'AST-Core'; package: 'Refactoring-Core'; load. 2. Select the code (packages) you want to fix: environment := BrowserEnvironment new forPackageNames: #('Connectors-Base' 'Connectors-Lines and Curves'). 3. Create the transformation rule: rule := RBUnderscoreAssignmentRule new. 4. Perform the search: SmalllintChecker runRule: rule onEnvironment: environment. 5. Perform the transformation: change := CompositeRefactoryChange new. change changes: rule changes. change execute
