Berkeley Yacc (byacc) is a reimplementation of the Unix parser generator Yacc, originally written by Robert Corbett in 1990, designed for compatibility with Yacc.[1] Due to its liberal license and because it was faster than the AT&T Yacc, it quickly became the most popular version of Yacc.[2] It has the advantages of being written in ANSI C and being public domain software.
It contains features not available in Yacc, such as reentrancy, which is implemented in a way that is broadly compatible with bison.[3][4]
