I guess it does strip attachments. For the benefits of the mailing
list, I'll inline the code (assuming gmail doesn't mess it up more
than it is already)...
----------------- testlex.c -----------------
/* Test Lexer for Lemon Parser */
#include <stdio.h>
#include <stdlib.h>
#include "testpar.h"
extern void *ParseAlloc(void *(*mallocProc)(size_t));
extern void Parse(void *, int, void *);
extern void ParseFree(void *, void (*freeProc)(void *));
extern void ParseTrace(FILE *stream, char *zPrefix);
int main()
{
void *pParser;
pParser = ParseAlloc(malloc);
if (!pParser)
{
printf("out of memory\n");
exit(1);
}
ParseTrace(stderr, "Debug: ");
Parse(pParser, LPC_CMDNAME, 0);
Parse(pParser, LPC_INTEGER, 0);
Parse(pParser, LPC_TEXT, 0);
Parse(pParser, LPC_EOL, 0);
Parse(pParser, LPC_CMDNAME, 0);
Parse(pParser, LPC_INTEGER, 0);
Parse(pParser, LPC_TEXT, 0);
Parse(pParser, LPC_EOL, 0);
Parse(pParser, 0, 0);
ParseFree(pParser, free);
return 0;
}
----------------- testpar.y -----------------
%include {
#include <assert.h>
}
%token_prefix LPC_
%parse_accept {

}
%parse_failure {
printf("Giving up...\n");

}
