TIP RandomTopicPlugin is not installed on Foswiki.org.


Pick and display some random topic names/links.

Syntax Rules

  • %RANDOMTOPIC% - inserts a single random topic name in its place.
  • %RANDOMTOPIC{params}% - inserts potentially more than one random topic, with user formatting. Parameters:
  • topics="5" - Number of topics requested. Default is 1 topic
  • include="^Web" - Perl regular expression. Only topics that match this expression will be shown. Default is set by RANDOMTOPICPLUGIN_INCLUDE (see below).
  • exclude="^Web" - Perl regular expression. Any topics that match this expression will never be shown. Default is set by RANDOMTOPICPLUGIN_EXCLUDE (see below).
  • format=" format string " . The format string accepts 3 quoted parameters:
    • $t will be expanded to \t (necessary for bullet lists)
    • $n will be expanded to \n (So that things appear on separate lines - again for bullet lists)
    • $topic will be expanded to the randomly chosen name
    • Default is a bullet list: "$t* $topic$n"


A single random topic:

5 random topics as a bullet list:

10 random topics as a table:
  header="| *Topic* |$n"
  format="| $topic |"

10 random topics, excluding any that start with "Web":
  separator=", "

Jump to a random topic:
%BUTTON{"I'm feeling lucky"
