Thanks lukas
I've commented
commited :) I guess I saw in on the rss feed :)
a version of RBConfigurableFormatter that can format #copyFrom: to the following code. This comes pretty close to the document of Adrian:
Object>>copyFrom: anotherObject "Copy to myself all instance variables I have in common with anotherObject. This is dangerous because it ignores an object's control over its own inst vars. "
<primitive: 168> | mine his | mine := self class allInstVarNames. his := anotherObject class allInstVarNames. 1 to: (mine size min: his size) do: [ :ind | (mine at: ind) = (his at: ind) ifTrue: [ self instVarAt: ind put: (anotherObject instVarAt: ind) ] ]. self class isVariable & anotherObject class isVariable ifTrue: [ 1 to: (self basicSize min: anotherObject basicSize) do: [ :ind | self basicAt: ind put: (anotherObject basicAt: ind) ] ]
can we get rid of the :ind | ;)
