[pmwiki-devel] New ##idName issue Re: Using "!#anchor heading" markup

[John Rankin]

Thanks, Petko. I think it must be something in the way Martin (cc'd) has 
configured his site. Martin, does your site use a custom (:include:) 
recipe at all? Can you think of anything your site is doing that might 
be triggering this?

I have been unable to replicate the problem on my test site, with a now 
quite old pmwiki version. 'Include' works as Iyou would expect with 
visible anchors in my case. The pagetoc code doesn't touch the standard 
markup rule for [[#idName]]. The code that handles [[##idName]] 
basically copies the stdmarkup logic for [[#idName]], and produces 
either a visible anchor or a visible duplicate as output, depending on 
the result returned from TrackAnchors. It also turns any !!#idName or 
!!##idName into their [[...]] equivalents. So pagetoc uses the same 
processing logic as the latest pmwiki version.

So it appears there is some interaction between the latest pagetoc code 
and Martin's site configuration causing this problem, not a pagetoc / 
pmwiki core interaction. See also Martin's reply.

Does the new MarkupAnchors() function replace TrackAnchors, or will 
pagetoc's call to TrackAnchors continue to work?
