This is ``docutils.parsers.rst`` package. It exports a single class, `Parser`,
the reStructuredText parser.
Usage
=====
1. Create a parser::
parser = docutils.parsers.rst.Parser()
Several optional arguments may be passed to modify the parser's behavior.
Please see `Customizing the Parser`_ below for details.
2. Gather input (a multi-line string), by reading a file or the standard
input::
input = sys.stdin.read()
3. Create a new empty `docutils.nodes.document` tree::
document = docutils.utils.new_document(source, settings)
See `docutils.utils.new_document()` for parameter details.
4. Run the parser, populating the document tree::
parser.parse(input, document)
Parser Overview
===============
The reStructuredText parser is implemented as a state machine, examining its
input one line at a time. To understand how the parser works, please first
become familiar with the `docutils.statemachine` module, then see the
`states` module.
Customizing the Parser
----------------------
Anything that isn't already customizable is that way simply because that type
of customizability hasn't been implemented yet. Patches welcome!
When instantiating an object of the `Parser` class, two parameters may be
passed: ``rfc2822`` and ``inliner``. Pass ``rfc2822=True`` to enable an
initial RFC-2822 style header block, parsed as a "field_list" element (with
"class" attribute set to "rfc2822"). Currently this is the only body-level
element which is customizable without subclassing. (Tip: subclass `Parser`
and change its "state_classes" and "initial_state" attributes to refer to new
classes. Contact the author if you need more details.)
The ``inliner`` parameter takes an instance of `states.Inliner` or a subclass.
It handles inline markup recognition. A common extension is the addition of
further implicit hyperlinks, like "RFC 2822". This can be done by subclassing
`states.Inliner`, adding a new method for the implicit markup, and adding a
``(pattern, method)`` pair to the "implicit_dispatch" attribute of the
subclass. See `states.Inliner.implicit_inline()` for details. Explicit
inline markup can be customized in a `states.Inliner` subclass via the
``patterns.initial`` and ``dispatch`` attributes (and new methods as
appropriate).
