Thank you for your reply !
It seems that we already have something done, after your suggestion I looked
at the sqlite3 sources and found this function:
#ifndef NDEBUG
/*
** Turn parser tracing on by giving a stream to which to write the trace
** and a prompt to preface each trace message.? Tracing is turned off
** by making either argument NULL
**
** Inputs:
** <ul>
** <li> A FILE* to which trace output should be written.
**????? If NULL, then tracing is turned off.
** <li> A prefix string written at the beginning of every
**????? line of trace output.? If NULL, then tracing is
**????? turned off.
** </ul>
**
** Outputs:
** None.
*/
void sqlite3ParserTrace(FILE *TraceFILE, char *zTracePrompt){
? yyTraceFILE = TraceFILE;
? yyTracePrompt = zTracePrompt;
? if( yyTraceFILE==0 ) yyTracePrompt = 0;
? else if( yyTracePrompt==0 ) yyTraceFILE = 0;
}
#endif /* NDEBUG */
Maybe it can be a possible answer for the original question ?
Anyone used it ?
What's it's output like ?
Cheers !
