On the definition of ELR(k) and ELL(k) grammars

  • 54 Accesses

Summary

Extended context free grammars are obtained by allowing regular expressions on the right hand sides of production rules of context free grammars. The LR(k) and LL(k) conditions are made applicable to these grammars by defining canonical transformations of extended grammars into context free grammars.
