[Cuis-dev] How to stop the editor asking to delete a certain variable ?

[Hernan Wilkinson]

Currently there is no way to configure that behavior.
The method that as for that is Parser>>#selectRemovableUnusedTempsFrom:

A quick trick you could do is to define the method #compilerClass in the
class you want that behavior to change (for example OSProcess). That new
compiler should subclass Compiler and redefine #parserClass with a subclass
of Parser that redefines #selectRemovableUnusedTempsFrom: to do nothing...
maybe it is not that quick but it will do it :-)

We can discuss if we want this behavior to be configurable and therefore
have a preference for that... we try to avoid preferences as much as
possible because they become difficult to remember, but maybe this is a
good place for a preference and if so, for all the others questions the
parser does (uninitialize variable, etc). If we make this configurable, it
would have a global impact (all the classes). We would do it per class
basis, but I'm not sure if it makes sense... anyway, what do you people
think? Does it make sense to make this configurable? Besides Nicola, is
there any other "user" for this?

BTW, I like Luciano's idea of use syntax highlighting for that...
