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

[Erik Itter]

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
