RE: string token

[Xinan Tang]

Hi

  Please remember that yytext is overwritten for each yylex() call. If
you need STR1, you have to copy it using strcpy(); otherwise STR2 will
overwrite yytext (yylval). 

  For example, 

       example : STR1 { printrf(STR1) } STR2 { printf(STR1);};

  will work. Please try to understand the difference.

Subject: string token

Hi,

I have a newbies problem, but could not find the solution.

My bison file has something like that :

%token <string> STR1
%token <string> STR2

example : STR1 STR2            { printf(STR1); printf(STR2);}
;

my flex has something like that :

[...]
"toto"    ncpy(yylval.string, yytext, yyleng); return STR1;
"tata"    ncpy(yylval.string, yytext, yyleng); return STR2;
[...]


Even the contains of STR1 and STR2 are different, my printf return me
the same string for STR1 and STR2.....


What's wrong ?

thx
