i’m struggling with this grammar for a few days now, and nothing really working,
so i started from beginning and i have :
grammar myGrammar;
options {
language = Java;
k=1;
}
rule: term ;
factor : '-'? NUMBER
;
term : factor '*' term
| factor '/' term
| factor '%' term
| factor;
NUMBER : '0'..'9'+
;
WS : ( ' '
| '\t'
| '\r'
| '\n'
) {$channel=HIDDEN;}
;
and i got errors:
warning(200): /ANTLR_TEST/myGrammar.g:13:7: Decision can match input such as
"'-'" using multiple alternatives: 1, 2, 3, 4
As a result, alternative(s) 2,3,4 were disabled for that input
|---> term : factor '*' term
warning(200): /ANTLR_TEST/myGrammar.g:13:7: Decision can match input such as
"NUMBER" using multiple alternatives: 1, 2, 3, 4
As a result, alternative(s) 2,3,4 were disabled for that input
|---> term : factor '*' term
error(201): /ANTLR_TEST/myGrammar.g:13:7: The following alternatives can never
be matched: 2,3,4
|---> term : factor '*' term
can anyone tell me what i’m doing wrong
