README.md

This tool, menhir-generate-printers, reads a .cmly file and produces code for three functions, namely print_symbol, print_value, and print_token.

val print_symbol: MenhirInterpreter.xsymbol -> string

By default, print_symbol prints the internal name of a (terminal or nonterminal) symbol. This can however be changed by attaching a [@name] attribute with this symbol. The attribute payload should be an OCaml expression of type string.

val print_value: 'a MenhirInterpreter.symbol -> 'a -> string
val print_token: token -> string

By default, print_value and print_token ignore the semantic value and print just the name of the symbol, like print_symbol. This can however be changed by attaching a [@printer] attribute with this symbol. The attribute payload should be an OCaml expression of type _ -> string, where _ stands for an appropriate type of semantic values.
