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. "

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 ​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 reference-directive 'trac' to allow TracLinks from within RST text.

Example:

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

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

For a complete example of all uses of the trac-directive, please see WikiRestructuredTextLinks.

• Trac allows an even easier way of creating TracLinks in RST, using the custom :trac: link naming scheme.

Example:

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

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

Syntax highlighting in reStructuredText

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

Example

{{{
#!rst

.. code-block:: python

 class Test:

    def TestFunction(self):
        pass

}}}

Will result in the below.

.. code-block:: python

 class Test:

    def TestFunction(self):
        pass

Wiki Macros in reStructuredText

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

Wiki Macro Example

{{{
#!rst

.. code-block:: RecentChanges

   Trac,3

}}}

Will result in the below:

Apr 24, 2020

• TracWorkflow (diff)
• TracWiki (diff)
• TracUpgrade (diff)

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

{{{
#!rst

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

Bigger ReST Example

The example below should be mostly self-explanatory:

{{{
#!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

Results in:
