Thanks for the answer. Now I wonder what is the way of putting that INTEGER
: ('0'..'9')+ to the tokens {} part of my tree grammar. I want this, because
I get no error for the tokens defined in tokens {} block in my tree grammar.
But I cannot do this directly as
tokens {
...
INTEGER = '0'..'9'+
...
}
I get an error of "Expecting SEMI, found '..'".
How can get rid of this error and put INTEGER token to tokens block?
