A '''lookahead LR parser (LALR) generator''' is a software tool that reads a [[context-
There are other types of [[parser generator]]s, such as [[Simple LR parser]], [[LR parser]], [[GLR parser]], [[LL parser]] and [[GLL parser]] generators. What differentiates one from another is the type of CFG which they are capable of accepting and the type of parsing algorithm which is used in the generated parser. An LALR parser generator accepts an LALR grammar as input and generates a parser that uses an LALR parsing algorithm (which is driven by LALR parser tables).
