1. Description

With this plugin the syntax of DokuWiki is extended to allow definition lists. <dl><dt>term</dt><dd>Term definition</dd></dl>

2. Syntax

  = Term : Definition of term.

There should be at least two spaces before '='.

3. Example

  = Item 1 : Definition of item 1.
  = Item 2 : Definition of item 2.
  = : Second definition of item 2.
  = Item 3 : Definition of item 3.
  = Item 4 : 
  = Item 5 : 
  = Item 6 : Definition of items 4 through 6.

Will be rendered as HTML code:

<dl>
  <dt>Item 1</dt>
    <dd>Definition of item 1.</dd>
  <dt>Item 2</dt>
    <dd>Definition of item 2.</dd>
    <dd>Second definition of item 2.</dd>
  <dt>Item 3</dt>
    <dd>Definition of item 3.</dd>
  <dt>Item 4</dt>
  <dt>Item 5</dt>
  <dt>Item 6</dt>
    <dd>Definition of items 4 through 6.</dd>
</dl>

8. Discussion

You can see it working on my page. — Pavel Vitis 2005-08-18 02:21

Pavel, you shouldn't pass raw wiki data unfiltered to the output document - it should at least go through an entity conversion function, e.g. $renderer→xmlEntities(). That will convert “<” & “>” to &lt; & &gt; and ensure no malicious HTML (or JavaScript) can be embedded in the wiki page. — Christopher Smith 2005-08-25 20:09

Omniting empty definition

If you wan to create something like this:

<dl>
  <dt>First Term</dt>
  <dt>Second Term</dt>
  <dd>Their definition</dt>
</dl>

You try to do this:

= First Term : 
= Second Term : Their definition

This is problematic when you try create something like this.

So, I prepare patch for this (correctDefinitions.patch):
