[ri4pp:2006] - Oporavak od grešaka (CUP) by Vaso Putica <vaso@putica.com>

Je l' ima neko ideju zašto dobijam grešku "Couldn't repair and continue 
parse Object" sa ovom gramatikom i test programom? Zar ne bi trebalo da 
"main_function ::= BEGIN error END" odradi oporavak pošto "error SEMI" 
ne može jer nedostaje ; iza x?


// CUP ----------------------------------
start with program;

program		::=	prog_decl main_function;
prog_decl	::=	PROGRAM ID SEMI;

main_function	::=	BEGIN END;	
main_function	::=	BEGIN statements END;
main_function	::=	BEGIN error END {: 
System.out.println("main_function_error");
:};


statements	::=	statement statements;
statements	::=	statement;


statement	::=	ID EQ INTEGER_LITERAL SEMI;
statement	::=	error SEMI {: System.out.println("statement error"); :};



// microJava ----------------------------------
program pp;
begin
	z=4;
	x
end.
