Hi community,
I want to use, e.g., the MINUS and the POSITIVE token for the '-'
literal. Is there a way to write it shorter than with rewrite rules?
For example, I want to replace the following
'-' unary_expression -> ^(NEGATIVE unary_expression);
by
'-'<NEGATIVE> unary_expression;
or
NEGATIVE['-'] unary_expression;
I know that and why the last two aproaches do not work. But perhaps
there is another way that I do not know so far.
Regards,
Christian
