hi,
the problem is related to following grammar:
grammar Sample;
start: (FLOAT | INTEGER) DOT IDENTIFIER;
FLOAT: NUMBER DOT NUMBER;
INTEGER: NUMBER;
IDENTIFIER: LETTER+;
DOT: '.';
fragment NUMBER: DIGIT+;
fragment LETTER: 'a' .. 'z';
fragment DIGIT: '0' .. '9';
let us try:
3.hello
result:
line 1:2 required (...)+ loop did not match anything at character 'h'
line 1:3 mismatched input 'ello' expecting set null
what should i do?
