Hi there...
I want to build a one-parse interpreter using flex/bison is this possible?
As I see it: simpel expresion and asignments works fine,
BUT: condition and loops :-(
Consider this test "gramma":
if-stmt : IF if-bool THEN true-stmt;
{dont-do=0;};
if-bool : bool:
{ don't-do=1;
$=$1;
};
stmt: id '=' value
{if (!dont-do) setvalue($1,$3) };
This might workbut look like h.... !
And what about a loops ?
