Yacc (Yet Another Compiler-Compiler) is a computer program for the Unix operating system developed by Stephen C. Johnson. It is a lookahead left-to-right rightmost derivation (LALR) parser generator, generating a LALR parser (the part of a compiler that tries to make syntactic sense of the source code) based on a formal grammar, written in a notation similar to Backus–Naur form (BNF).[1] Yacc is supplied as a standard utility on BSD and AT&T Unix.[2] GNU-based Linux distributions include Bison, a forward-compatible Yacc replacement.[3]
