Hi,
Is there any example of using the parser control predicates to customize the Ciao grammar?
Hi Mark,
You can customize the Ciao grammar using operator definitions, like in most Prolog systems. This is powerful enough for many purposes. Additionally, the parser has some experimental flags to allow more exotic syntax like array subscript ("A[B]").
It is also possible to plug custom parsers by doing some tricks with the compiler hooks. If you can provide us some concrete example of customization, we could help you with some code and a more precise answer.
