differently organized method categories in the Debugger dnu: create process
by Paul DeBruicker 01 Nov '12

01 Nov '12

Hi- When I create methods using the Debugger's 'Create' button I am never sure which categories are used in the class I'm adding the method to versus those in its super classes. In an effort to not have to think about that any more I've adapted the ClassDescription>>#allMethodCategoriesIntegratedThrough: to put the method categories that are used in the target class first, then those in the super classes after that. I think this should work in Pharo and Squeak but I've only tested it in Pharo 1.4. I've attached a changeset and also pasted the method below Paul allMethodCategoriesIntegratedThrough: mostGenericClass "Answer a list of all the method categories of the receiver and all its superclasses, up through mostGenericClass" | otherClassCategories thisClassCategories combinedClassCategories | otherClassCategories := OrderedCollection new. self allSuperclasses do: [ :aClass | (aClass includesBehavior: mostGenericClass) ifTrue: [ otherClassCategories addAll: aClass organization categories ] ]. otherClassCategories remove: 'no messages' asSymbol ifAbsent: [ ]. thisClassCategories := self organization categories asSortedCollection: [ :a :b | a asLowercase < b asLowercase ]. ^ Array streamContents: [ :stream | stream nextPutAll: thisClassCategories; nextPutAll: ((otherClassCategories asSet removeAllSuchThat: [ :each | thisClassCategories includes: each ]) asSortedCollection: [ :a :b | a asLowercase < b asLowercase ]) ]

OMeta2 minor bug
by Douglas McPherson 01 Nov '12

Hi, I think there's a small problem with the semantic predicate of the range rule: range :a :b = anything:x ?[a <= x & x <= b] -> [x] A pair of parenthesis fixes the problem: range :a :b = anything:x ?[a <= x & (x <= b)] -> [x] Thanks, Doug

Smalltalk to Python and back
by dimitris chloupis 01 Nov '12

Probably I have mentioned this several times but I am working on a project for visual programming targeting 3d app blender. I am using currently pharo though I am still interested in squeak too and I have decided that in order to communicate with blender python to use a socket bridge. My project is named "Ephestos". Now what was wondering is the following, how difficult it would be to parse smalltalk to python. Ephestos is of course smalltalk , and blender uses python for its addon system. It would be great if extensions made in Ephestos could converted to python addons. I am already planning to map smalltalk methods to Blender python api call, but I was wondering how easy it would be to parse that code to python. So far I am aware of OMeta and Petit Parser libraries. What are your suggestions ?
