This will output the steps the parser does (reduce, shift, fallback,...) but not the syntax tree.

J?nner 2016 15:55 An: SQLite mailing list Betreff: Re: [sqlite] Wish list: allow developers use the power ofsqliteparser 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 ?
