Thanks, tried

scanSpecialCharacter
�� | character |
�� currentCharacter = $:
�� ifTrue: [
�� self step.
�� ^ currentCharacter = $=
�� ifTrue: [
�� self step.
�� RBAssignmentToken start: tokenStart]
�� ifFalse: [ RBSpecialCharacterToken value: $: start: tokenStart ]].
��
�� currentCharacter = $:
�� ifTrue: [
�� self step.
�� ^ currentCharacter = $>
�� ifTrue: [
�� self step.
�� RBAssignmentToken start: tokenStart]
�� ifFalse: [ RBSpecialCharacterToken value: $: start: tokenStart ]].
��
�� currentCharacter = $_ ifTrue: [
�� self step.�
�� ^ RBShortAssignmentToken start: tokenStart ].
��
�� character := currentCharacter.
�� self step.
�� ^ RBSpecialCharacterToken value: character start: tokenStart

but while it does not seem to shred my image to pieces it also seems to have no effect at all. I guess the UI components still check differently and neither workplace nor SystemBrowser allow me to write code using the :> operator

Hi,

If you are using the OpalCompiler (Pharo4, sure, Pharo3, I'm not so sure), have a look at:

RBScanner>>scanSpecialCharacter

Hi,

I need to modify the compiler adding ":>" as an alias for ":=" for assignment. I have been reading all over the Compiler package but do not find where a tokenizer parses for the assignement operator or where it is defined.

Any hint where to start or do it is appreciated.

best regards
Erik
