What is a .mlyacc file?

File Extension Details

The mlyacc file format is a specialized input file used by the ML-Yacc parser generator, which is a tool primarily associated with the Standard ML (SML) programming language. It serves as a specification file that defines the grammar of a language in Backus-Naur Form (BNF). An mlyacc file typically contains three distinct sections: the user declarations, the ML-Yacc definitions (such as token declarations, precedence rules, and start symbols), and the grammar rules themselves, which include semantic actions written in SML code. When processed, the ML-Yacc tool reads this file and generates an SML source file containing a parser function. This parser is then used by compilers, interpreters, or data processing tools to transform a stream of tokens into an abstract syntax tree (AST) or other structured representations. It is a critical component for developers building domain-specific languages or full-scale programming language compilers within the SML ecosystem, providing a robust way to handle complex syntax parsing through LALR(1) parsing techniques.
