Re: [Pharo-users] modifying the compiler adding an alias for :=

Dec. 10, 2014

      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
