Hello,
I work on multiple parser's in a GUI. When I start 1st, the code
generation is fine. But, when I start 2nd start, the code generator
produce some junk. I have used "yyterminate();" but this seems to not
help.
The source:
? "Ploppers" + "ppp" + "huhu"
The pre-processed text file:
#output asm, cli
? "Ploppers" + "ppp" + "huhu"
The first pass (flex):
1: "Ploppers"
plus
2: "ppp"
plus
2: "huhu"
The second pass:
#output asm, cli? 2: "Ploppers"
plus
2: "ppp"
plus
2: "huhu"
Segmentation fault
\#"output cpp" { outype = 0; return _CPP_PARSER_; }
\#"output asm" { outype = 1; return _ASM_PARSER_; }
\#"output asm, cli" { outype = 1; return _ASM_PARSER_; }
(\"([a-zA-Z0-9_])*\")* {
printf("1: %s\n",yytext); strcpy(yytext,"");
BEGIN(STRINGER);
strcpy(yytext,"");
}
<STRINGER>{
(\"([a-zA-Z0-9_])*\")* { printf("2: %s\n",yytext);
strcpy(yytext,""); BEGIN(STRINGER); strcpy(yytext,"");
}
\+ { printf("plus\n"); BEGIN(STRINGER); }
\n
}
I would like use it in gnu "bison" so:
string_expr
: _STRING_ { printf("---> %s\n",yylval.text); }
;
Is that a Bug, or my mistakes?
TIA
Jens
