Simple precedence grammar

From Wikipedia, the free encyclopedia

A simple precedence grammar is a context-free formal grammar that can be parsed with a simple precedence parser.[1] The concept was first created in 1964 by Claude Pair,[2] and was later rediscovered, from ideas due to Robert Floyd, by Niklaus Wirth and Helmut Weber who published a paper, entitled EULER: a generalization of ALGOL, and its formal definition, published in 1966 in the Communications of the ACM.[3]

Formal definition

[edit]

G = (N, Σ, P, S) is a simple precedence grammar if all the production rules in P comply with the following constraints:
