Is there a way to define tokens which have a fixed length?
Say I would like to define a lexer rule N3 which defines a token of
three and another N4 of four numeric characters.
Something like this:
test: N3 N4;
N3: Digit Digit Digit; // This in combination with N4 does not
work
N4: Digit Digit Digit Digit; //
fragment
Digit: '0'..'9'
Thanks
