Here's what I'm trying to parse:

buffer
buffer+20
buffer-20
buffer^
buffer^+20
buffer^-20
buffer#
buffer#+20
buffer#-20

Here's what I've tried as a Data Type rule:

SPINMEM: {SPINMEM} ID ('#' | '^')? ('+' INT)?;

However, it doesn't work properly.

Ideally, I would get two String parameters:

"buffer", and everything after "buffer" (or null). Although the Data Type rule above only maps to 1 argument.

Hi

this is not a datatype rule.

it would look like

SPINMEM: ID ('#' | '^')? ('+' INT)?;

you could use a valueconverter to handle the buffer cutting.

Thanks again Christian, that worked great! I started putting the { RULENAME } in, because I had some rules with no arguments, and Xtend gave me a warning that those rules wouldn't be instantiated unless I added the { RULENAME } in curly brackets. However I don't know WHY this is the case and I obviously used this inappropriately.
