Yet Another Compiler Compiler

The computer program yacc is a parser generator developed by Stephen C. Johnson at AT&T for the Unix operating system. The name is an acronym for "Yet Another Compiler Compiler." It generates a parser (the part of a compiler that tries to make syntactic sense of the source code) based on an analytic grammar written in a notation similar to BNF. Yacc generates the code for the parser in the C programming language.

<tool, language> (yacc) The LALR parser generator found on most Unix systems. Also, the language used to describe the syntax of another language to yacc (the program).
Implementations: ayacc, YAY, perln-byacc,
SASL-Yacc - "Yacc in SASL - An Exercise in Functional Programming", Simon Peyton-Jones, Software Prac & Exp 15:807-820 (1985). Mentions also a BCPL implementation.
Yacc++ - 1990. An object-oriented rewrite of yacc, supports regular expressions, produces an LR1 grammar parser.
