[Zope-CMF] Re: Re-working Breadcrumbs

[Thomas Olsen]

I doubt that this is less expensive - and it doesn't even show the title - 
just a ZPT way of doing it :-)

<span tal:define="
        path python:here.portal_url.getRelativeUrl(here);
        steps python:modules['string'].split(path, '/');
        last python:steps.pop();
        breadcrumbs python:[];
        url here/portal_url">
    <span tal:replace="here/Type">Object</span> at
    <span tal:condition="path" tal:repeat="step steps"><a
    href=""
    tal:define="dummy python:breadcrumbs.append(step); vstep 
python:here.truncID(step, size=15)"
    tal:attributes="href python:'/'+modules['string'].join(breadcrumbs, '/')"
    tal:content="string:/${vstep}">Step</a></span>
    <span tal:replace="string:/${last}">/Last</span>
</span>
