Re: [Pharo-users] RB refactoring rewrite variable to a symbol

Nov. 13, 2017

      Thanks Thierry, I'll try it out!

re werner: ... the other question was about the tool, because it was a very
nice tool to write and tweak rewrite rules

Hi Peter,
i assume from your question "RewriteTool maintained?" that you want to
make a RBTransformationRule, right? if yes, i once had a similar problem
and overwrote only #checkMethod:
checkMethod: aMethod
    | arg |
    arg := aMethod argumentNames first asString.
    self initialize.
    self rewriteRule
        replace:
            '| ``@temporaries1 |
            `.@Statement'
        with:
            ('| ``@temporaries1 |
            {1} blahblah ifTrue: [ ^ {1} adaptToNumber: self andSend:
#{2}].
            `.@Statement'
                format: {arg. aMethod selector}).
    ^ super checkMethod: aMethod
not too elegant, but it works. you could strip ":" from the method
selector and do something similar.

Hi,
how can I rewrite a(n instance) variable to a symbol?
E.g.
[IN]
something: aSomething
    something := aSomething
[OUT]
something: aSomething
    self write: aSomething into: #something
I can capute the input just fine... ``@var := ``@arg
but I have no idea how to convert the var into a symbol (or string).
Thanks,
Peter
