I think this is an example that exposes a bug that we still have in the source mappingâ¦ on Context, see sourceNode "Return the source node of the method or the block corresponding to the receiver" ^ (method sourceNodeForPC: self neighborPCWithCorrectMapping) enclosingMethodOrBlockNode "Uncomment the following once the pc->AST mapping is fixed" "^ (method sourceNodeForPC: (pc ifNil: [ self startpc ])) enclosingMethodOrBlockNode" #neighborPCWithCorrectMapping returns the inner send, which is wrongâ¦ this method needs to be rethought.

BlockClosure source code

by Jan KurÅ¡

Hi, I need to extract a source code from a block closure and I found something strange: [ :ctx | [ ctx atEnd ] ifTrue: [ ] ] . [ :ctx | [ ctx atEnd ] whileTrue:[ ] ]. Print of the first line returns: '[ :ctx | [ ctx atEnd ] ifTrue: [ ] ]' Print of the second line returns: '[ ctx atEnd ]' And honestly, I have no idea why. This behaviour was observed in Pharo3 and Pharo4. Is there a way how to get a consistent result, i.e. '[ :ctx | [ ctx atEnd ] whileTrue:[ ] ]' for a second line? Thank you in advance! Jan

it did not had sense so is removed :) showPackages: true = showHierarchy: false. So now we just have one message.
