Item11231: TOC + WikiWord = bad anchor

The href anchor in the TOC has the exclamation mark ('!'), but the name anchor does not.

Hrm, that seems to not work on my 1.1.3. Let me see if I can reproduce it on this site. Sorry.

WIKIWORD in the TOC above does not link properly.

Although I now realise that WIKIWORD shouldn't need an exclamation mark ('!') in front of it. Probably another bug in how I'm using the wikiWordRegex in my version of the MediaWiki conversion script.

-- JayenAshar - 02 Nov 2011

Jayen, WIKIWORD would auto-link as an acronym if the topic exists, but not generate a "missing link" questionmark. Acronyms are a bit different in that they only link when the topic exists. So there is a case where WIKIWORD might be needed.

Ah... I see what you mean. The headings both use exclamation point escape - !WikiWord and !ACRONYM The first heading generates an anchor and reference without exclamation point. The 2nd heading encodes the Exclamation point into the anchor reference in the toc, #A_33WIKIWORD but not into the anchor itself, which is simply #WIKIWORD.

Confirmed. But just for the ACRONYM case.

I think there is a simple fix. filters out escaped WikiWords but not Abbreviations. The following seems to fix it for me.

diff --git a/core/lib/Foswiki/Render/ b/core/lib/Foswiki/Render/

Committed a fix to both 1.1 and trunk. So this topic should now work correctly on

-- GeorgeClark - 03 Nov 2011

Sorry my explanation was so vague. Glad you understood it.

Is it worth making a autoLinkRegex for WikiWord|ABBREV and use that in a bunch of places?
