Hi All,
� in ParseNode>>printCommentOn: there is the most perplexing
destructive modification of a comment on printing:
printCommentOn: aStream indent: indent
� � � � | thisComment |
� � � � self comment == nil ifTrue: [^ self].
� � � � 1 to: self comment size
� � � � �do: [:index |
� � � � � � � � � � � �index > 1 ifTrue: [aStream crtab: indent].
� � � � � � � � � � � �aStream nextPut: $".
� � � � � � � � � � � �thisComment := self comment at: index.
� � � � � � � � � � � �self printSingleComment: thisComment
� � � � � � � � � � � � � � � � � � � �on: aStream
� � � � � � � � � � � � � � � � � � � �indent: indent.
� � � � � � � � � � � �aStream nextPut: $"].
�!! � � self comment: nil
� The result is that a parse tree can only be printed once before it
prints without comments. �Can anyone justify this? �I would like to
remove it; it makes no sense to me.
best
Eliot
