Introduction yacc2latex translates a yacc or ocamlyacc (mly) file into an hopefully pretty EBNF grammar, and then in Latex.
For language developers, it’s rather tedious and error-prone to write and maintain a reference (printable and readable) grammar of their language. Indeed, the “actual” grammar independent from the “actual” one, often written in yacc or mlyacc.
yacc2latex allows to “compile” a yacc/mly source into a latex file that can be easily integrated into the reference manual of the language (supposing that latex is used for document processing).
Yacc2latex generates human-readable EBNF grammars from yacc files. Output format is in Latex and fairly customizable.
Distribution yacc2latex is available under LGLP licence

Goal As a language designer, I often faced the problem of writing and maintaining a reference (readable) grammar of my language. This is particularly annoying since the reference grammar actually exists as a yacc (or ocamlyacc) file, so why not use a “compiler” that will derived automaticaly the reference grammar from the yacc file ?
