The Yacc concept has frequently been ported to other languages. Some of the early ports are extinct along with the languages that hosted them; others have been superseded by parser skeletons shipped with Bison.
However, independent implementations persist. One of the best-known still in use is David Beazley’s “PLY” (Python Lex-Yacc) for Python. Another is goyacc, supporting the Go language. An “ocamlyacc” is shipped as part of the Ocaml compiler suite.
