unfoldDead :: (EqFam phi, FoldFam phi, MemoFam phi) => GContextFreeGrammar phi r t rr -> GContextFreeGrammar phi r t rrSource
Unfold dead non-terminals in a given context-
free grammar, such
that the unfolded references can be filtered with the
filterDies algorithm. This uses the isDead algorithm
to detect dead non-terminals.
unfoldDeadE :: (EqFam phi, FoldFam phi, MemoFam phi) => GExtendedContextFreeGrammar phi r t rr -> GExtendedContextFreeGrammar phi r t rrSource
Unfold dead non-terminals in a given extended context-
free grammar, such
that the unfolded references can be filtered with the
filterDies algorithm. This uses the isDead algorithm
to detect dead non-terminals.
unfoldDeadLE :: (EqFam phi, FoldFam phi, MemoFam phi) => GLExtendedContextFreeGrammar phi r t rr -> GLExtendedContextFreeGrammar phi r t rrSource
Unfold dead non-terminals in a given extended liftable context-
free grammar, such
that the unfolded references can be filtered with the
filterDies algorithm. This uses the isDead algorithm
to detect dead non-terminals.
