authors (basic) The WikiTrails feature allows wiki authors to create "trails" through sequences of pages in the wiki.
Before you can use a trail through a group of pages, you have to create a "trail index" on a separate page, which we will call the "trail index page". On that trail index page, you simply create a numbered or bulleted list of links. (So every numbered or bulleted list of links implicitly creates a trail.) It is important that each page name (link) be the first item following each bullet.
An example trail index page: a list like
* [[TrailPage1]] * Some text. (This won't be in the trail.) * [[TrailPage2]] ** [[TrailPage3]] ** [[TrailPage4]] some other text [[IrrelevantWikiPage]] ** Yet some other text. [[AnotherIrrelevantWikiPage]]. (This won't be in the trail.) ** %center%[[would-beTrailPage]] (This won't be in the trail.)
creates the following "wikitrail":
TrailPage1 <-> TrailPage2 <-> TrailPage3 <-> TrailPage4
What makes a trail "work" is adding trail markup on the pages in the trail (i.e. the pages that are listed in the bullet/numbered list on the trail index page).
To build a trail, add trail markup like
<<|[[TrailIndexPage]]|>> to a page, where TrailIndexPage is the page, described above, containing the bulleted list of pages in the trail. PmWiki will display the trail markup with links to any previous and next pages in the trail.
The trail markup can be placed anywhere in a page, and a page can contain multiple trail markups. If you are adding a trail to every page in a group, consider setting the trail markup in the GroupHeader or GroupFooter pages instead of on every individual page in your group.
PmWiki defines 2 trail markups:
<<|[[TrailIndexPage]]|>>displays as "<< PreviousPage | TrailIndexPage | NextPage >>".
<|[[TrailIndexPage]]|>displays as "< PreviousPage | TrailIndexPage | NextPage >", except the appropriate arrow is omitted at the beginning and end of the trail.
^|[[TrailIndexPage]]|^ treats the list levels as a hierarchy and displays the "path" to reach the current page (i.e., a "breadcrumb" trail). In the example trail above, the markup
TrailPage4 would display as "TrailIndexPage | TrailPage2 | TrailPage4".
Wiki administrators can change the trail separator of the "path" trail (
^|[[TrailIndexPage]]|^ ) from the default | by setting the variable $TrailPathSep in the config.php file. For instance $TrailPathSep = ' > '; will output "TrailIndexPage > TrailPage2 > TrailPage4".
Typically, a trail is a linear list with a first and a last page. However, the trail can be made "circular" by repeating the first page as the last item in the trail index:
* [[TrailPage1]] * [[TrailPage2]] ... * [[TrailPageN]] * [[TrailPage1]]
If the trail index page is intended to be read by others, the last item can be made invisible using
* [[TrailPage1]] * [[TrailPage2]] ... * [[TrailPageN]] * [[TrailPage1]] %item comment%
Trail pages on both sides of group boundaries must be fully qualified with group names.
%trail% markup that is used in many of PmWiki's documentation pages is just a WikiStyle that creates a grey background, and is not required for WikiTrails to work. It's defined in the PmWiki.GroupHeader page.
To get it to work, you must create the index page for the trail and the trail pages as stated above. Then you must define the wikistyle you want in the groupheader of the group you want it to appear in. Then you must refer or call to it with the
%trail% markup from the trail pages.
