TreePlugin

Enables dynamic generation of TWiki topic trees based on topics' parent-child relationships.

Useful for dynamic sitemaps and threads.

Alpha release. Documentation will be enhanced. More features finalized.

TreePlugin Global Settings

Plugin settings are stored as preferences variables. To reference a plugin setting write %<plugin>_<setting>%, for example, %INTERWIKIPLUGIN_SHORTDESCRIPTION%

  • One line description, shown in the TextFormattingRules topic:
    • Set SHORTDESCRIPTION = Dynamic generation of TWiki topic trees

  • Set DEBUG to 1 to get debug messages in data/debug.txt. Default: 0
    • Set DEBUG = 0

Syntax Rules

Adds the following tags:

  • %TREEVIEW% - displays a TWiki topic's children in a hierarchical fashion.

Attributes:

  • web - specify web
  • topic - specify tree's root topic (if none, will do the entire web)
  • formatting - specify the formatting method
  • stoplevel - the depth of the tree to show
  • header - header output
  • bookview - list topics in BookView form
  • format - specify the format for each node (outline & coloroutline). Format variable options:
    • $topic - the topic name
    • $web - the topic's web
    • $spacetopic - the topic with spaces
    • $summary - the topic's summary
    • $text - the topic's text (which will get rendered)
    • $author - the topic's last author
    • $modTime - the topic's modification time
    • $level - the tree depth of the topic (in whatever format)
    • $count - the topic's child position
    • $onum - outline number for the topic (eg, 1.3.4.2)
    • $url - the current topic's URL
  • formatbranch - specify the format for a group of children (outline & coloroutline)
    • $parent - the text of a node
    • $children - the text of all the node's children (if any)

See TreePluginSamples for samples usage and output.

Limitations and Known Issues

  • The parameter web does not work correctly. The Tree gets rendered, but the WikiWords of the topics do not contain the web value, but refers to the current web. Since I have limited knowledge of perl OO, I can't repair for now. -- MartinRaabe - 16 Jan 2003
