I have an IEEE language definition that looks like so:
noun-field:
{ noun |
noun-name } [ "USING" label-identifier ];
now my first thought is that in bisonland this would look like so (I have
omitted dependencies)
noun_field:
{ noun | noun_name }
| noun_field USING_TOKEN label_identifier
;
but then this will match
noun USING label USING label USING label....
which I don't want.
I couldn't find anything in the docs that said anything about how to limit
sequences.
Can anyone point me in the right direction ?
Thanks,
Alfonso.
