Non-deterministic Recursive Ascent Parsing

Authors: nan

Publication: TIPSTER (1991)

DOI: nan

A purely functional implementation of LR-parsers is given, together with a simple correctness proof. It is presented as a generalization of the recursive descent parser. For non-LR grammars the time-complexity …...
