Plugin errors on semantic predicate options #63

Open sgparry opened 6 years ago

sgparry commented 6 years ago

Semantic predicates with fail options, e.g.:

ints[int max]
locals [int i=1]
: INT ( ',' {$i++;} {$i<=$max}?<fail={"exceeded max "+$max}> INT )*
;

are treated as syntax errors by the plugin.
