PetitParser instance variables

Administrator

I wanted my PPCompositeParser subclass to save some values as it parses. But when I added an instance variable, class>>parse: failed with "Error: Unable to initialize #[instVar name]"

How do I save these intermediate results? Is it not possible to have inst vars for my own purposes?

Sean

Hi,

You need to specify these instance variables in the following method:

MyParser class>>ignoredNames
"Answer a collection of instance-variables that should not be automatically initialized with productions, but that are used internal to the composite parser."

Cheers,
Doru
