3 Converting yacc or bison Grammars
| (require parser-tools/yacc-to-scheme) |
procedure
(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.
