What is a .mly file?

File Extension Details

An MLY file is a source code file used by Menhir, which is a powerful LR(1) parser generator designed specifically for the OCaml programming language. Menhir serves as a modern and more capable alternative to the older ocamlyacc tool. The file contains a formal grammar specification, which typically consists of declarations for terminal and non-terminal symbols, precedence rules, and production rules associated with semantic actions written in OCaml code. When the Menhir compiler processes a .mly file, it generates OCaml source code (typically .ml and .mli files) that implements a functional and efficient parser for the defined language or data format. This file type is a cornerstone for developers building compilers, interpreters, or complex domain-specific languages within the OCaml ecosystem. It offers advanced features such as parameterized non-terminals, improved error reporting, and a more flexible syntax compared to legacy tools. Because .mly files contain embedded OCaml logic, they are best handled by text editors that support OCaml syntax highlighting and the Menhir grammar format to ensure code correctness and readability.
