reStructuredText Support in Trac
Introduction
Trac supports reStructuredText (RST) as an alternative to wiki markup where 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 to be displayed as reStructuredText in the Trac source browser, set text/x-rst as the value for the Subversion property svn:mime-type, or add the extension rst to the filename. See this example.
The examples will only be rendered as reStructuredText if docutils is installed. If Pygments is installed but docutils is not installed, the examples will be syntax-highlighted rather than rendered as reStructuredText.
Requirements
To activate RST support in Trac, install the python docutils package with the command easy_install docutils, or through your operating system package manager. If not already available on your operating system, you can download it from PyPI.

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 |
|---|---|
{{{#!rst
This is a reference to |a ticket|
.. |a ticket| trac:: #42
}}}
| This is a reference to |a ticket| .. |a ticket| trac:: #42 |
- You can also use the custom
:trac:role to create TracLinks in RST.
| Wiki Markup | Display |
|---|---|
{{{#!rst
This is a reference to ticket `#12`:trac:

:trac:role, see WikiRestructuredTextLinks.
Syntax highlighting in reStructuredText
There is a directive for doing TracSyntaxColoring in RST as well. The directive is called code-block:
| Wiki Markup | Display |
|---|---|
{{{#!rst
.. code-block:: python
class Test:
def TestFunction(self):
pass
}}}
|
.. 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
To enable Wiki Macros in RST, you use the same code-block directive as for syntax highlighting:
| Wiki Markup | Display |
|---|---|
{{{#!rst
.. code-block:: RecentChanges
Trac,3
}}}
| .. code-block:: RecentChanges Trac,3 |
Or use the :code-block: role for a more concise Wiki Macro-like syntax:
| Wiki Markup | Display |
|---|---|
{{{
#!rst
:code-block:`RecentChanges:Trac,3`
}}}
| :code-block:`RecentChanges:Trac,3` |

The example below should be self-explanatory:
