Dear all,
I would like to parse integers and simple floats without exponents. Is this
the correct grammar?
class MyLexer extends Lexer;
options {
k=2;
}
NUMBER : INT ((FLOAT)?)
;
protected
FLOAT : ('.' INT)
;
protected
INT : (DIGIT)+
;
protected
DIGIT : '0'..'9'
;
WS :
(' '
| '\t'
| '\r' '\n' { newline(); }
| '\n' { newline(); }
)
{ $setType(Token.SKIP); }
;
