## summary
at times it is useful to have a guided tour or trail through a subset of the pages of a wiki; in pmwiki, this is implemented as [wikitrails](http://www.pmwiki.org/wiki/PmWiki/WikiTrails).
+### smcv's implementation
+
+... is the out-of-tree [[plugins/trail]] plugin, see there for details.
+
+> And will be the one landing in ikiwiki. So, I'm closing this bug report. [[done]] --[[Joey]]
+
+### chrysn's implementation
+
i'm working on a python xmlrpc plugin for ikiwiki to support wikitrails, both as a navigation feature (have "forward" and "back" links based on a sequence) and a modified inline that includes all pages in the trail with appropriate modifications (suitable for printing if necessary).
-the current status is published on `git://github.com/github076986099/ikiwiki-plugins.git`; as of now, i don't have a public demo of it.
+the current status is published on `git://prometheus.amsuess.com/ikiwiki-plugins`; as of now, i don't have a public demo of it.
feedback on both the concept and the code is very much appreciated by [[discussion]] or [email](mailto:chrysn@fsfe.org).
-## usage
+> update as of 2013: this implementation is kept in said ikiwiki-plugins directory for historical reference only; with the implementation nowadays available in ikiwiki, my implementation is obsolete. --[[chrysn]]
+
+#### usage
two preprocessor commands are provided:
-### \[[!trail index="my_indexpage"]]
+##### \[[!trail index="my_indexpage"]]
embeds a navigation object with forward and back links as well as an indicator of the current position in the trail.
this works very well together with the [[sidebar|plugins/sidebar]] plugin if the pages in a directory are roughly the same as the pages in the trail and the `index` is directory index page; just put the \[[!trail]] in the sidebar.
-### \[[!trailinclude index="my_indexpage"]]
+##### \[[!trailinclude index="my_indexpage"]]
all pages linked from the index page are included in the same way as \[[!inline]] does, but in the proper sequence, with headings according to the indent in the source page and adoptions for the headings inside the page (a level 2 heading in a page that is a sub-sub-chapter in the whole trail will become a level 5 heading when trailincluded).
-## the index page
+#### the index page
the index page is parsed as markdown; numbered lists and "`*`" bulleted lists are discovered.
-## current issues
+#### current issues
* rebuilding --- currently, there is no propper rebuilding of pages (will use `will_render` and `add_depends`). care has to be taken of how not yet created pages play into this.
* inline recursion --- there is simply no guard yet
