[[TracGuideToc]]

Wiki markup is a core feature in Trac, tightly integrating all the other parts of Trac into a 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://moinmoin.wikiwikiweb.de/ MoinMoin]. 


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


== Font styles ==

The Trac wiki supports the following font styles:
{{{
 * '''bold'''
 * ''italic''
 * '''''bold italic'''''
 * __underline__
 * {{{monospace}}} or `monospace`
 * ~~strike-through~~
 * ^superscript^ 
 * ,,subscript,,.
}}}

Display:
 * '''bold'''
 * ''italic''
 * '''''bold italic'''''
 * __underline__
 * {{{monospace}}} or `monospace`
 * ~~strike-through~~
 * ^superscript^ 
 * ,,subscript,,.



== 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. 

Example:
{{{
= Heading =
== Subheading ==
=== About ''this'' ===
}}}

Display:
= Heading =
== Subheading ==
=== About ''this'' ===


== 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.
There must be a space preceding the star "*" or number "1.", or nothing will happen.

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


== Definition lists ==

The wiki also supports definition lists.

Example:
{{{
 llama::
   some kind of mammal, with hair
 ppython::
   some kind of reptile, without hair
   (can you spot the typo?)
}}}

Display:
 llama::
   some kind of mammal, with hair
 ppython::
   some kind of reptile, without hair
   (can you spot the typo?)

Note that you need a space in front of the defined term.


== 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||

Note that more complex tables can be created using
[wiki:WikiRestructuredText#BiggerReSTExample reStructuredText].

== Links ==

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

Example:
{{{
 TitleIndex, http://www.edgewall.com/, !NotAlink
}}}

Display:
 TitleIndex, http://www.edgewall.com/, !NotAlink

Links can be given a more descriptive title by writing the link followed by
a space and a title and all this inside square brackets. 
If the descriptive title is omitted, then the explicit prefix is disguarded,
unless the link is an external link. This can be useful for wiki pages
not adhering to the WikiPageNames convention.

Like this:
{{{
 * [http://www.edgewall.com/ Edgewall Software]
 * [wiki:TitleIndex Title Index]
 * [wiki:ISO9000]
}}}

Display:
 * [http://www.edgewall.com/ Edgewall Software]
 * [wiki:TitleIndex Title Index]
 * [wiki:ISO9000]


=== 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: r1, [1] or changeset:1
 * Revision Logs: r1:3, [1:3] or log:branches/0.9-stable#1:3
 * Wiki pages: CamelCase or wiki:CamelCase
 * Milestones: milestone:1.0 or milestone:"End-of-days Release"
 * Files: source:trunk/COPYING
 * A specific file revision: source:/trunk/COPYING#200
 * A filename with embedded space: source:"/trunk/README FIRST"
}}}

Display:
 * Tickets: #1 or ticket:1
 * Reports: {1} or report:1
 * Changesets: r1, [1] or changeset:1
 * Revision Logs: r1:3, [1:3] or log:branches/0.8-stable#1000:2000
 * Wiki pages: CamelCase or wiki:CamelCase
 * Milestones: milestone:1.0 or milestone:"End-of-days Release"
 * Files: source:trunk/COPYING
 * A specific file revision: source:/trunk/COPYING#200
 * A filename with embedded space: source:"/trunk/README FIRST"

See TracLinks for more in-depth information.


== Escaping Links and WikiPageNames ==

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>)

Example:
{{{
 ----
}}}

Display:
----
