Bonjour 
 
J'ai un petit compilateur à écrire en javacc et je rencontre un problème: javacc semble reconnaitre le token le plus grand en priorité :/ 
Le code et l'erreur parle d'eux même je pense. > 
options { 
STATIC = false ; 
} 
PARSER_BEGIN(Adder) 
class Adder { 
public static void main( String[] args ) 
throws ParseException, TokenMgrError { 
Adder parser = new Adder( System.in ) ; 
parser.Start() ; } 
} 
PARSER_END(Adder) 
 
SKIP : 
{ 
"\r" 
} 
 
TOKEN : 
{ 
< NUMBER: (["0"-"9"])+> 
&#124; < WORD : (~[" ","\n"])+> 
&#124; < WORDS: (&#124;" ")+> 
&#124; < EOL: ("\n")> 
} 
 
void Start() : 
{ 
int n; 
Token t; 
} 
{ 
(t = 
{ 
n = Integer.parseInt(t.image); 
System.out.println(n); 
} 
" " 
" " 
 
)+ 
 
} 
 
 
 echo "123 mot1 mot2 mot3" &#124; java Adder 
 Exception in thread "main" ParseException: Encountered " "123 mot1 mot2 mot3 "" at line 1, column 1. 
 Was expecting: 
 £spaces£ £/spaces£... 
 £spaces£ £/spaces£ 
 £spaces£	£/spaces£at Adder.generateParseException(Adder.java:190) 
 £spaces£	£/spaces£at Adder.jj_consume_token(Adder.java:128) 
 £spaces£	£/spaces£at Adder.Start(Adder.java:13) 
 £spaces£	£/spaces£at Adder.main(Adder.java:6) 
 
 
 
Merci d'avance :)> /
