Earley algorithm
WebEarley’s parsing algorithm [1, 2] is a general algorithm, capable of parsing according to any context-free grammar. (In comparison, the LALR(1) parsing algorithm used in Yacc … WebA GLR parser (GLR standing for "Generalized LR", where L stands for "left-to-right" and R stands for "rightmost (derivation)") is an extension of an LR parser algorithm to handle non-deterministic and ambiguous grammars. The theoretical foundation was provided in a 1974 paper by Bernard Lang (along with other general Context-Free parsers such as GLL). It …

Webnearley is the first JS parser to use the Earley algorithm (insert your own ‘early bird’ pun here). It also implements Joop Leo’s optimizations for right-recursion, making it … WebEssentially, instead of storing a sequence of sets of items like in the original algorithm, the modified algorithm just stores pointers back to sets of reachable items. The worst-case run time performance of the Earley parsing algorithm is cubic in the length of the input, but for large classes of grammars it is linear.
