4 Converting yacc or bison Grammars🔗

 (require parser-tools/yacc-to-scheme)
  package: parser-tools-lib


(trans file)  any/c

  file : path-string?
Reads a C yacc/bison grammar from file and produces an s-expression that represents a Racket parser for use with parser.

This function is intended to assist in the manual conversion of grammars for use with parser, and not as a fully automatic conversion tool. It is not entirely robust. For example, if the C actions in the original grammar have nested blocks, the tool will fail.

Annotated examples are in the "examples" subdirectory of the "parser-tools" collection.
