Hi folks...while browsing AutomaticMethodCategorizer I found the place where the rules are defined. It is cool becuase we can add the rules we want. I am all ears. For now, it is doing this: defaultCategorizationRules "The order is relevant, the categorizer uses the first rule matching - DF" ^OrderedCollection new add: MethodCategorizationRule forAccessors; add: (MethodCategorizationRule whenSelectorMatches: 'initialize*' categorizeIn: #initialization); add: (MethodCategorizationRule whenSelectorMatches: 'is*' categorizeIn: #testing); add: (MethodCategorizationRule whenSelectorMatches: 'has*' categorizeIn: #testing); add: (MethodCategorizationRule whenSelectorMatches: '=' categorizeIn: #comparing); add: (MethodCategorizationRule whenSelectorMatches: 'hash' categorizeIn: #comparing); add: (MethodCategorizationRule whenSelectorMatches: 'default*' categorizeIn: #defaults); add: (MethodCategorizationRule whenSelectorMatches: 'printOn:' categorizeIn: #printing); add: (MethodCategorizationRule whenSelectorMatches: 'accept:' categorizeIn: #'visitor accepting'); add: (MethodCategorizationRule whenSelectorMatches: 'visit*:' categorizeIn: #visiting); add: (MethodCategorizationRule whenSelectorMatches: 'value' categorizeIn: #evaluating); add: (MethodCategorizationRule whenSelectorMatches: 'test*' andClassInheritsFrom: TestCase categorizeIn: #tests); add: MethodCategorizationRule usingMostUsedCategoryInSuperClasses; add: MethodCategorizationRule usingMostUsedCategoryInImage; yourself We should improve this guy.... ideas to add/change?
