history
Project history and usage
Menhir is an LR(1) parser generator for OCaml, created in 2005 by François Pottier and Yann Régis-Gianas. Its manual presents it as a generator that turns grammar specifications plus semantic actions into parsers, based on Knuth's LR(1) construction and inspired by yacc, ML-Yacc, and ocamlyacc while adding more modern capabilities.
Project history
The project history is unusually well documented in its README. Régis-Gianas contributed the early front-end for parsing and transforming .mly grammar files, while Pottier contributed the LR(1) construction algorithms, conflict explanations, and first OCaml code backend. A table backend using menhirLib followed in 2008 with Jane Street Capital funding through the OCaml Summer Project. Jacques-Henri Jourdan implemented a Coq-table backend in 2011. Frédéric Bour contributed the incremental API, inspection API, attributes, and MenhirSdk between 2014 and 2017. The build moved to Dune in 2019, and Émile Trotignon and Pottier implemented a new efficient, well-typed code backend around StackLang in 2021.
How it is used
Menhir's ecosystem role is as the richer successor-style tool for OCaml parser generation. OCaml developers feed it .mly grammar files and receive parser .ml/.mli output, either as standalone generated code or table-backed parsers linked with MenhirLib. The opam package page lists many reverse users, including compiler, verification, parsing, and developer-tooling packages, which matches its place as infrastructure for OCaml language tooling.
