WebParsers¶. Lark implements the following parsing algorithms: Earley, LALR(1), and CYK. Earley¶. An Earley Parser is a chart parser capable of parsing any context-free grammar at O(n^3), and O(n^2) when the grammar is unambiguous. It can parse most LR grammars at O(n). Most programming languages are LR, and can be parsed at a linear time.
