Can I create a custom breadcrumbs root?

Hi,

I'm setting up a new wiki, and I want to create a custom breadcrumbs trail. The default breadcrumb trail looks something like this:

You are here: Foswiki>Main Web>WebHome

But I want it to look like this:

You are here: ETH Zurich>de Mello Group>Main Web>WebHome

Where "ETH Zurich" links to the ETH Zurich web page, http://ethz.ch, and "de Mello Group" links to http://demellogroup.ethz.ch, which is the root of our wiki.

Is this possible? If so, how do I do it?

Renaming Foswiki to de Mello Group is straight-forward. Just go to SitePreferences on your wiki and change the definition of WIKITOOLNAME to de Mello Group.

The second part is a bit harder. If you're using PatternSkin you have to overwrite the breadcrumb template as explained in this guide. The breadcrumb definition is set in templates/view.pattern.tmpl:

%TMPL:DEF{"breadcrumb:separator"}%<span class='foswikiSeparator'>&gt;</span>%TMPL:END%
%TMPL:DEF{"breadcrumb"}%%TMPL:P{"breadcrumb:title"}%%TMPL:P{"breadcrumb:wikitoolname"}%%TMPL:P{"breadcrumb:currentweb"}%%TMPL:P{"breadcrumb:parents"}%%TMPL:P{"breadcrumb:currenttopic"}%%TMPL:END%
%TMPL:DEF{"breadcrumb:parents"}%%META{"parent" nowebhome="on" prefix="%TMPL:P{"breadcrumb:separator"}%" separator="%TMPL:P{"breadcrumb:separator"}%" suffix=""}%%TMPL:END%
%TMPL:DEF{"breadcrumb:topic"}%<nop>%TOPIC%%TMPL:END%
%TMPL:DEF{"breadcrumb:title"}%<span class="patternHomePathTitle">%MAKETEXT{"You are here:"}% </span>%TMPL:END%
%TMPL:DEF{"breadcrumb:wikitoolname"}%[[%USERSWEB%.%HOMETOPIC%][%WIKITOOLNAME%]]%TMPL:END%
