Re: Regex in Archetypes must include TYPE
Well the problem here is that the specifications don't actually say anything about the regexes, or even that you have to use regexes to identify archetypes in slots - it is just one way of doing it. So any tools today that take a particular approach to regexes are already outside the standard. I think what we should probably do is to state that regexes, if used, must be assumed to be usable as a filter on whole archetype ids without prior modification. This still does not prevent some tool using the short regexes now in use in the archetype editor, since the clearly can be used at a technical level - it is just that they might create errors. And there may be some short patterns which are actually correct. I'm not sure how we can formally state this.... - thomas Peter Gummer wrote: > Thomas Beale wrote: > >> I also agree with Adam.
