Converting to RST
=================

Installing pandoc
-----------------

Pandoc is a powerful document-transformation utility. We'll use it to do simple conversions, but it is capable of much more. Visit the `pandoc website <http://pandoc.org/installing.html>`_ for installation instructions for your platform.

Converting
----------

Using a terminal, navigate to the directory containing the documents you wish to convert. Next, issue the following command for each file you'd like to convert:

:code:`pandoc -s --toc -f <from format> -t rst myfile.<from format>`

:code:`-s` tells pandoc to produce a standalone document

:code:`--toc` tells pandoc to produce a table of contents (optional)

:code:`-t` tells pandoc to produce reStructuredText output

:code:`-f` tells pandoc the input format. It should be one of the following:

+--------------------+---------------------------------------------------------------+

Fixing the converted document
-----------------------------

How much you'll need to fix the converted document depends on which file format you're converting from. Here are a couple of things to watch out for:

1. Multi-line titles need to be converted to single line
2. Standalone "**" characters
3. :code:`***bolded***` should be :code:`**bolded**`
4. Mangled tables

Previewing edits
----------------

Web-based
~~~~~~~~~

`rst.ninjs.org <http://rst.ninjs.org>`_ has an excellent RST previewing tool that highlights RST errors with line numbers.
