Thank you! The way I was thinking about it, it wouldn't compile, thinking |
took precedence.

I'm having trouble with ! Is there some combination of ![a-zA-Z0-9]+ that

There's a few ways you can do it. You should be able to use
parenthesis to use '!':
alpha = [a-zA-Z0-9]
rule =
TUPLE: digits text ;
TUPLE: punc text ;
TUPLE: upper text ;
TUPLE: lower text ;
TUPLE: whitespace text ;
EBNF: categorize
digits = [0-9]+ = [[ string digits boa ]]
lower = [a-z]+ = [[ string lower boa ]]
upper = [A-Z]+ = [[ string upper boa ]]
punc = [!-/:-...@[-`{-~]+ = [[ string punc boa ]]

Change this to:
ws = ( | \t) = [[ string whitespace boa ]]
In the first case the = is binding to the \t part of the clause.
Chris.
