====== Breadcrumbs ======

In [[DokuWiki]] you will never get lost because you always leave some breadcrumbs behind which show you the way back.

===== Breadcrumb Types =====

DokuWiki can display two kinds of breadcrumbs: tracking and hierarchical breadcrumbs.

==== Tracking Breadcrumbs ====

This is the default. Breadcrumbs display a list of pages you just visited in a wiki. This makes most sense for pages with a flat [[namespace]] hierarchy. Tracking Breadcrumbs are prefixed with the word ''Trace: • ''.

The number of tracking breadcrumbs to be shown can be set with the [[config:breadcrumbs]] option.

==== Hierarchical Breadcrumbs ====

Hierarchical breadcrumbs are common in typical CMS driven sites with deep navigation structures. If your wiki features strict hierarchical [[namespaces]], you might want to use these bookmarks. When enabled they are prefixed with the words ''You are here:''.

Hierarchical breadcrumbs can be enabled with the [[config:youarehere]] option.

===== Configuration =====
  * [[config:breadcrumbs]] Set to 0 to disale it.
  * [[config:youarehere]]

==== Breadcrumb Prefixes ====

* The text blocks ''Trace:'' for [[#tracking breadcrumbs]] and ''You are here:'' for [[#hierarchical breadcrumbs]] (including the punctuation character) prefixing the breadcrumbs cannot be customized overally by means of the [[plugin:config|Configuration Manager]].
  * How and where the breadcrumb block is rendered is mainly the responsibility of the template.
  * The [[template]] [[template:mikio]] with a highly customizable [[template:mikio#configuration]] has a setting ''breadcrumbPrefixText'' for your customization: Note though that this is only a single prefix used for all [[#breadcrumb types]] and not individually per [[#hierarchical breadcrumbs]] and [[#tracking_breadcrumbs]].
  * If you'd like to customize it in your [[plugin]] of choice
    * ask the author, to make it customizable,
    * or find the string in the template and overwrite it as a quick hack to get what you want
    * or alternatively try to see what the [[localization]] has to offer in that regard.

===== Development =====

The breadcrumbs are stored in the user session. [[Template]] developers should make sure to provide space for both types of breadcrumbs by using the ''tpl_breadcrumbs()'' and ''tpl_youarehere()'' functions.
