Hello, I am new to ANTLR and I'd appreciate help with my problem. At first some grammar rules I am going to talk about:
DIGIT: '0'..'9'; LETTER: 'a'..'z'|'A'..'Z'; REAL : (DIGIT)+ '.' (DIGIT)* EXPONENT? | '.' (DIGIT)+ EXPONENT? | (DIGIT)+ EXPONENT ; INTEGER: DIGIT+; IDENTIFIER: LETTER+; range_expr: expr ('..' expr)?; expr: expratom ('+' expratom)?; expratom: INTEGER | REAL | IDENTIFIER; This grammar allows '1.' and .1' as correct real numbers. Also, it allows range expression '1..2', which gets parsed incorrectly as two real numbers 1. and .2. Redefining token INTEGER: DIGIT '..'?; doesn't help, because then also valid range expression 'i + 1..2'. Is there any way how to parse the '..' correctly in all cases? Thank you very much, Ondrej.
