I don't understand how to use aClass definition from workspace nor I understand your selector message.��

(aClass compiledMethodAt: self selector) sourceCode , self would imply that i try to operate this from inside another class with self selector being the method itself at the time executed ?

No, just that you can write:

(Object compiledMethodAt: #printString) sourceCode

That's me not sanitizing my code samples (lifting it from the AltBrowser)

However because I try to parse pharo syntax to python code, the classes that I am parsing are��unrelated��to the parser class itself ��so I don't see how self selector would be relevant here.��

I also don't understand��

�� �� ast := RBParser parseMethod: aTarget text asString onError: [ :msg :pos | ^ self ].
�� �� ast doSemanticAnalysisIn: self sourceClass

what is aTarget ?

Ok, as above, it should be understood as:

ast := RBParser parseMethod: (Object compiledMethodAt: #printString) onError: [ :msg :ps | ].
ast doSemanticAnalysisIn: self sourceClass.

There is ��a method on CompiledMethod called #ast��that called��the parser +��semantic analysis:

( Object compiledMethodAt: #halt ) ast

No need to know details about RBParser.

as example how to query the AST see the method #accessesSlot:

accessesSlot: aSlot

self ast nodesDo: [ :node |��

node isVariable and: [

node isInstance and: [��

(node binding slot == ��aSlot)

ifTrue: [^true]]]].��

^false
