[Flex-help] Flex Initial States

[Nikos B. <nba...@gm...>]

Hi,

I have the following flex piece of code:

%x PLAYBACK IDIR TABLES SKIPLN HEX

<PLAYBACK>{
^Tuner\ set\ to\ [^\n]+    {
                                        BEGIN(HEX);
                                        yy_push_state(SKIPLN);
                                    }
[^\n]+                            |
\n                                 {}
}


<IDIR>{
{path}                    {
                                memcpy(indexDir, yytext, yyleng);
                                if (indexDir[yyleng - 1] != '/')
                                {
                                    indexDir[yyleng] = '/';
                                    indexDir[yyleng + 1] = '\0';
                                }
                                else indexDir[yyleng] = '\0';
                            }
.{6}                       {
                                fprintf(stderr, "Error: loadConfig ~>
Illegal text \"%s\" in group "
                                      "\"rainbow\" of \"sdmp.conf\"
(line:%d)\n", yytext, lineno);
                                yyterminate();
                                do_exit(13);
                             }
\n                          {
                                lineno++;
                                yy_push_state(TABLES);
                             }
}

I am calling it from my C Program:

A) BEGIN(IDIR);
yylex();


At a different part I call:
B) BEGIN(PLAYBACK);
yylex();

My problem is that in (A), if it gets the Error in <IDIR> instead of
exiting flex du to yyterminate(), it just jumps to <PLAYBACK> and continues
scanning the wrong rules. <PLAYBACK> is nowhere in the rulepath of <IDIR>.
How can I keep those 2 ruletrees separate and when I use yyterminate() have
yylex() exit?

TIA,
Nikos
