[racket] How to use parser-tools/yacc-to-scheme?

[亀田馬志]

Hello.

I prepared a tiny-tiny file having this(test.l):

%{
%}
%%
a(b|c)* { printf("OK\n"); } /*Finding this pattern shows O.K.*/
. {printf("NG\n");} /*. shows ELSE */
%%
/* Nothing */

And now, as the document of Parser Tools says, try runnning these command.

(require parser-tools/yacc-to-scheme)
(trans "./test.l")

It gives me something like an error:

<unsaved editor>:3:2: lexer: No match found in input starting with:

Did I misunderstand or do something wrong?

Thanks.

You are confused lexer with parser.
That is invalid as yacc format file.
