= reStructuredText Support in Trac =

Trac supports using ''reStructuredText'' (RST) as an alternative to wiki markup in any context WikiFormatting is used.

From the reStucturedText webpage:
 "''reStructuredText is an easy-to-read, what-you-see-is-what-you-get plaintext markup syntax and parser   system. It is useful for in-line program documentation (such as Python docstrings), for quickly creating  simple web pages, and for standalone documents. reStructuredText is designed for extensibility for  specific application domains. ''"

If you want a file from your Subversion repository be displayed as reStructuredText in Trac's source browser, set `text/x-rst` as value for the Subversion property `svn:mime-type`. See [trac:source:/trunk/INSTALL this example].

=== Requirements ===
Note that to activate RST support in Trac, the python docutils package must be installed. 
If not already available on your operating system, you can download it at the [http://docutils.sourceforge.net/rst.html RST Website].

Install docutils using `easy_install docutils`. Do not use the package manager of your OS (e.g. `apt-get install python-docutils`), because Trac will not find docutils then.

== Using RST in Trac ==
To specify that a block of text should be parsed using RST, use the ''rst'' processor. 

=== TracLinks in reStructuredText ===

 * Trac provides a custom RST directive `trac::` to allow TracLinks from within RST text.

 Example:
 {{{
 {{{
 #!rst
 This is a reference to |a ticket|

 .. |a ticket| trac:: #42
 }}}
 }}}

 * Trac allows an even easier way of creating TracLinks in RST, using the custom `:trac:` role.

 Example:
 {{{
 {{{
 #!rst
 This is a reference to ticket `#12`:trac:

 To learn how to use Trac, see `TracGuide`:trac:
 }}}
 }}}

 For a complete example of all uses of the `:trac:` role, please see WikiRestructuredTextLinks. 


=== Syntax highlighting in reStructuredText ===

There is a directive for doing TracSyntaxColoring in RST as well. The directive is called
code-block

Example

{{{
{{{
#!rst

.. code-block:: python

 class Test:

    def TestFunction(self):
        pass

}}}
}}}

Will result in the below.

{{{
#!rst

.. code-block:: python

 class Test:

    def TestFunction(self):
        pass

}}}

=== Wiki Macros in reStructuredText ===

For doing [WikiMacros Wiki Macros] in RST you use the same directive as for syntax highlighting i.e
code-block. To work you must use a version of trac that has [trac:ticket:801 #801] applied. 

=== Wiki Macro Example ===

{{{
{{{
#!rst

.. code-block:: RecentChanges

   Trac,3

}}}
}}}

Will result in the below:

     [[RecentChanges(Trac,3)]]

Or a more concise Wiki Macro like syntax is also available:

{{{
{{{
#!rst

:code-block:`RecentChanges:Trac,3`
}}}
}}}

=== Bigger RST Example ===
The example below should be mostly self-explanatory:
{{{
#!html
<pre class="wiki">{{{
#!rst
FooBar Header
=============
reStructuredText is **nice**. It has its own webpage_.

A table:

=====  =====  ======
   Inputs     Output
------------  ------
  A      B    A or B
=====  =====  ======
False  False  False
True   False  True
False  True   True
True   True   True
=====  =====  ======

RST TracLinks
