                 TonicRepetitionRule

A special unary rule for expanding the lexicon to add tonic repetition categories, generated from the tonic categories already in the lexicon.

This doesn't get used during parsing, but only to generate the full lexicon when it's loaded up.

It will expand any tonic category: X[T] => X[T]/X[T] : \x.x

apply_rule(self, cat_list, proc_sems=None)

source code

*** This should be overridden by subclasses. *** Applies the rule to combine the categories in cat_list.

Note that the returned semantics should always be in beta-normal form.

Returns:: a list of the possible categories resulting from the application if the rule is valid for the given arguments, otherwise None.
