= WikiFormatting =

Wiki markup is a core feature in Trac, tightly integrating all the other parts of Trac into flexible and powerful whole.

Trac has a built in small and powerful wiki rendering engine. This wiki engine implements an ever growing subset of the commands from other popular Wikis especially [http://moin.sf.net/ MoinWiki]. 

This page demonstrates the formatting syntax available anywhere WikiFormatting is allowed.

== Font styles ==

The Trac wiki support the following font styles: '''bold''', ''italic'',
__underline__, ~~strike-through~~, and `monospace`.

== Heading ==

You can create heading by starting a line with one up to five ''equal\\ '=' characters
followed by a single space and the headline text. The line should end with a space 
followed by the same number of ''equal'' characters. 

''Note: As of writing, headings cannot contain TracLinks.''

=== Example: ===
{{{
= Heading =
== Subheading ==
}}}


== Paragraphs ==

A new text paragraph is created whenever two blocks of text are separated
by one or more empty lines.

A forced line break can also be inserted, using:
{{{
Line 1[[BR]]Line 2
}}}
Display:

Line 1[[BR]]Line 2

  Text paragraphs can be indented by starting the lines with two or more spaces.

== Lists ==
The wiki supports both ordered/numbered and unordered lists.

Example:
{{{
 * Item 1
   * Item 1.1
 * Item 2

 1. Item 1
   1. Item 1.1
 1. Item 2
}}}
Display:
 * Item 1
   * Item 1.1
 * Item 2

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

== Preformatted text ==
Block quotes, preformatted text, are suitable for source code snippets, notes and examples. Use three ''curly braces'' wrapped around the text to define a block quote:
  
Example:
{{{
 {{{
  def HelloWorld()
      print "Hello World"
 }}}
}}}

Display:
{{{
 def HelloWorld()
     print "Hello World"
}}}

== Tables ==

Simple tables can be created like this:
{{{
||Cell 1||Cell 2||Cell 3||
||Cell 4||Cell 5||Cell 6||
}}}
Display:
||Cell 1||Cell 2||Cell 3||
||Cell 4||Cell 5||Cell 6||

== Links ==

!Hyperlinks are automatically created for WikiPageNames and urls. !WikiPageLinks can be disabled by
prepending an exclamation mark (!) character, such as {{{!WikiPageLink}}}.

Examples:

 TitleIndex, http://www.edgewall.com/.

Links can be given a more descriptive title by writing the link followed by
a space and a title and all this inside two square brackets. Like this:
{{{
 * [http://www.edgewall.com/ Edgewall Software]
 * [wiki:TitleIndex Title Index]
}}}
Display:

 * [http://www.edgewall.com/ Edgewall Software]
 * [wiki:TitleIndex Title Index]

=== Trac Links ===

Wiki pages can link directly to other parts of the Trac system.
Pages can refer to tickets, reports, changesets, milestones, source files and
other Wiki pages using the following notation:
 * Tickets: '''!#1''' or '''!ticket:1'''
 * Reports: '''!{1}''' or '''!report:1'''
 * Changesets: '''![1]''' or '''!changeset:1'''
 * Wiki pages: '''CamelCase''' or '''!wiki:CamelCase'''
 * Milestones: '''!milestone:1.0'''
 * Files: '''!source:trunk/COPYING'''
 * A specific file revision: '''!source:/trunk/COPYING#200'''
Display:
 * Tickets: #1 or ticket:1
 * Reports: {1} or report:1
 * Changesets: [1] or changeset:1
 * Wiki pages: CamelCase or wiki:CamelCase
 * Milestones: milestone:1.0
 * Files: source:trunk/COPYING
 * A specific file revision: source:/trunk/COPYING#200

See TracLinks for more in-depth information.

== Escaping Links and WikiNames ==
You may avoid making hyperlinks out of TracLinks by preceding an expression with a single '!' (exclamation mark).

{{{
 !NoHyperLink
 !#42 is not a link
}}}

Display:
 !NoHyperLink
 !#42 is not a link

== Images ==

Urls ending with .png, .gif or .jpg are automatically interpreted as image links, and converted to IMG tags.

Example:
{{{
http://www.edgewall.com/gfx/trac_example_image.png
}}}
Display:

http://www.edgewall.com/gfx/trac_example_image.png

== Macros ==
Macros are ''custom functions'' to insert dynamic content in a page. See WikiMacros for usage.

Example:
{{{
 [[Timestamp]]
}}}
Display:
 [[Timestamp]]

== Processors ==
Trac supports alternative markup formats using WikiProcessors. For example, processors are used to write pages in [wiki:WikiRestructuredText reStructuredText] or [wiki:WikiHtml HTML]. 

See WikiProcessors for more information.

'''Example 1:'''
{{{
#!html
<pre class="wiki">{{{
#!html
&lt;h1 style="text-align: right; color: blue"&gt;HTML Test&lt;/h1&gt;
}}}</pre>
}}}
Display:
{{{
#!html
<h1 style="text-align: right; color: blue">HTML Test</h1>
}}}

'''Example 2:'''
{{{
#!html
<pre class="wiki">{{{
#!python
class Test:
    def __init__(self):
        print "Hello World"
if __name__ == '__main__':
   Test()
}}}</pre>
}}}
Display:
{{{
#!python
class Test:
    def __init__(self):
        print "Hello World"
if __name__ == '__main__':
   Test()
}}}

== Miscellaneous ==

Four or more dashes will be replaced by a horizontal line (<HR>)
