Ticket #1017 (closed todo: wontfix)
recognize the <a b c> form of alternation
|Reported by:||coke||Owned by:||pmichaud|
A <?before> rule with a space between the '<' and the '?' compiles but fails at execution with the unhelpful message : Unable to find regex '' Null PMC access in invoke() -- cognominal stef
I agree that this is not a useful error message. However, when PGE is corrected to follow the specification the regex < ?before foo> would be identical to '?before' | 'foo' and no error message would be generated at all. (PGE hasn't been updated to recognize the < a b c > form of alternation.) Pm
