Lists#

Bold, italics, links, pre can be embedded in lists. Whitespace is optional before and after the * or # character, however a space is required afterwards if someone wishes to start a list element with bold text. A list element ends at the end of a line. It is recommended to have support for a depth of at least five levels.

About unordered lists and bold: a line starting with ** (including optional whitespace before and afterwards), immediately following an unordered list element a line above, will be treated as a nested unordered list element. Otherwise it will be treated as the beginning of bold text. Also note that bold and/or italics cannot span lines in a list.

Unordered Lists#

Creole:

* Item 1
** Item 1.1
* Item 2

Recommended XHTML:

<ul>
<li>Item 1
  <ul>
  <li>Item 1.1</li>
  </ul>
</li>
<li>Item 2</li>
</ul>

Sample Output:

• Item 1
  • Item 1.1
• Item 2

Ordered Lists#

Creole:

# Item 1
## Item 1.1
# Item 2

Recommended XHTML:

<ol>
<li>Item 1
  <ol>
  <li>Item 1.1</li>
  </ol>
</li>
<li>Item 2</li>
</ol>

Sample Output:

1. Item 1
   1. Item 1.1
2. Item 2

Headings#

Only three different sized levels of headings are required. Closing (right-side) equal signs are optional. If both left side and right side equal signs exist, the left side takes precedence. Whitespace is not allowed before the left-side equal signs. Only whitespace characters are permitted after the closing equal signs. No linebreaks are allowed within headings. Bold, italics, links and preformatted text are not allowed in headings.

Creole:

= Level 1 (largest) =
== Level 2 ==

<h3>Level 3</h3>
<h4>Level 4</h4>
<h5>Level 5</h5>
<h6>Level 6</h6>
<h3>Also level 3</h3>
<h3>Also level 3</h3>
<h3>Also level 3</h3>
<h3>**not** //parsed//</h3>

Links - Internal and External#

Any markup except for images within a link will not be parsed.

<a href="http://www.examplewiki.com/MyBigPage">Go to my page</a>
<a href="http://www.wikicreole.org/">http://www.wikicreole.org/</a>

<a href="http://www.wikicreole.org/">Visit the WikiCreole website</a>
<a href="http://www.examplewiki.com/Weird_Stuff">**Weird** //Stuff//</a>

This is more text.

<p>
followed by a paragraph
</p>

Preformatted#

This works in-line or as a block. No wiki markup is interpreted between these characters and all characters become monospace. As a block, the three curly braces should be on one line by itself to open and another line of three curly braces should be on a line by itself to close.

Creole:

{{{
//This// does **not** get [[formatted]] 
}}}

Recommended XHTML:

<pre>
//This// does **not** get [[formatted]]
</pre>

//This// does **not** get [[formatted]]

Some examples of markup are: <tt>** <i>this</i> **</tt>

Sample output:

Some examples of markup are: ** <i>this</i> **

Horizontal Rule#

Whitespace is optional before and after the hyphens, but no whitespace is allowed between them. The four hyphens must be the only characters (other than whitespace) on that line.

Creole:

 ---- 

Recommended XHTML:

 <hr /> 

Image (inline)#

Creole:

 {{myimage.png|this is my image}} 

Recommended XHTML:

 <img src="myimage.png" alt="this is my image"/> 

Tables#

All cells are separated by single pipes. The ending pipe is optional. You can embed links, bold, italics, monospace and line breaks in table cells. Comparison details found on List Of Table Markups

Creole:

|Heading Col 1  |Heading Col 2          |
|Cell 1.1       |Two lines\\in Cell 1.2 |
|Cell 2.1       |Cell 2.2               |

</tr>

<td>Cell 2.2</td>
</tr>
</table>

Sample output:

Heading Col 1	Heading Col 2
Cell 1.1	Two lines in Cell 1.2
Cell 2.1	Cell 2.2

Placeholder#

When there is something advanced, a placeholder will show up, so users will not be confused seeing more than one syntax. (optional for wiki developers)

Creole:

 <<x>>
