It's too big to make much sense of, but here's a couple of things you
can try:
I'd be surprised if it works. Have you tried column_method_name both
with and without brackets? The default is to ignore the brackets - what
happens then? How are the brackets interpreted?
without brackets it is relation or variable atribute. With brackets it
is methods.
The grammar produces no code for the no-brackets case ("relation or
variable attribute"). It doesn't reduce; it assumes that you wanted the
shift, so it assumes "with brackets it is methods". Is this acceptable,
or not? Have you got any test input that explicitly requires the
no-brackets "relation or variable attribute" case?
You need to post everything that can come after 'column_method'. Is it
ever possible to have a '(' character after a column_method, apart from
the 2 ways you have shown?
To rephrase this: if your intention is to allow both of these two things:
1 - column_method, with no following '(' (ie. "relation or variable
attribute"), *but* some other part of the grammar allows you to put in a
following '(' anyway, AND
2 - column_method with a following '(' (ie. "with brackets it is
methods"), THEN
you have a language ambiguity that you need to fix. At first sight, it
seems that perhaps you may want case 1, because (at least) both
func_name and qualified_name can be followed by '('. If you don't know
the answer, you need to go right through the grammar to find out if case
1 is a requirement.
