= 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.
   ||= Wiki Markup ||= Display ||
   {{{#!td
     {{{
     {{{
     #!rst
     This is a reference to |a ticket|

     .. |a ticket| trac:: #42
     }}}
     }}}
   }}}
   {{{#!td
     {{{
     #!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.

=== Syntax highlighting in reStructuredText ===

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

||= Wiki Markup ||= Display ||
{{{#!td
  {{{
  {{{
  #!rst

  .. code-block:: python

     class Test:

         def TestFunction(self):
             pass
  
  }}}
  }}}
}}}
{{{#!td
  {{{
  #!rst

  .. code-block:: python

     class Test:

         def TestFunction(self):
             pass

  }}}
}}}
Note the need to indent the code at least one character after the `.. code-block` directive.

=== Wiki Macros in reStructuredText ===

For doing [WikiMacros Wiki Macros] in RST you use the same directive as for syntax highlighting i.e code-block.

||= Wiki Markup ||= Display ||
{{{#!td
  {{{
  {{{
  #!rst

  .. code-block:: RecentChanges

     Trac,3

  }}}
  }}}
}}}
{{{#!td
  {{{
  #!rst

  .. code-block:: RecentChanges

     Trac,3

  }}}
}}}

Or a more concise Wiki Macro like syntax is also available, using the `:code-block:` role:

||= Wiki Markup ||= Display ||
{{{#!td
  {{{
  {{{
  #!rst

  :code-block:`RecentChanges:Trac,3`
  }}}
  }}}
}}}
{{{#!td
  {{{
  #!rst

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

=== Bigger RST Example ===
The example below should be mostly self-explanatory:

||= Wiki Markup ||= Display ||
{{{#!td
{{{
#!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
