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). reStructuredTextN)rolesstates)frontendnodes) universalceZdZdZdZ ejjjddddgde j dfd d gd d e j d fddgd ddfddgde j dfddgd de j d fddgddde j dfddgde j dfdd gd!d"d#fd$d%ggd&d'd(d)fd*d+gd,d-e j d.fd/d0gd1d2e jd3fd4d5gd!d6d#fd7d8gdd,d6d9ff fzZd:Zd;Zd?d<Zfd=Zd>ZxZS)@ParserzThe reStructuredText parser.)rstrestructuredtextrestrestxrtxtrstxzreStructuredText Parser OptionsNzARecognize and link to standalone PEP references (like "PEP 258").z--pep-references store_true)action validatorzABase URL for PEP references (default "https://peps.python.org/").z--pep-base-urlzzhttps://peps.python.org/)metavardefaultrz7Template for PEP file part of URL.

The following attributes may be set by subclasses. They are interpreted by the directive parser (which runs the directive class): - `required_arguments`: The number of required arguments (default: 0). - `optional_arguments`: The number of optional arguments (default: 0). - `final_argument_whitespace`: A boolean, indicating if the final argument may contain whitespace (default: False). - `option_spec`: A dictionary, mapping known option names to conversion functions such as `int` or `float` (default: {}, no options). Several conversion functions are defined in the directives/__init__.py module. Option conversion functions take a single parameter, the option argument (a string or ``None``), validate it and/or convert it to the appropriate form. Conversion functions may raise `ValueError` and `TypeError` exceptions. - `has_content`: A boolean; True if content is allowed. Client code must handle the case where content is required but not supplied (an empty content list will be supplied). Arguments are normally single whitespace-separated words. The final argument may contain whitespace and/or newlines if `final_argument_whitespace` is True. If the form of the arguments is more complex, specify only one argument (either required or optional) and set `final_argument_whitespace` to True; the client code must do any context-sensitive parsing. When a directive implementation is being run, the directive class is instantiated, and the `run()` method is executed. During instantiation, the following instance variables are set: - ``name`` is the directive type or name (string). - ``arguments`` is the list of positional arguments (strings). - ``options`` is a dictionary mapping option names (strings) to values (type depends on option conversion functions; see `option_spec` above). - ``content`` is a list of strings, the directive content line by line. - ``lineno`` is the absolute line number of the first line of the directive. - ``content_offset`` is the line offset of the first line of the content from the beginning of the current input. Used when initiating a nested parse. - ``block_text`` is a string containing the entire directive. - ``state`` is the state which called the directive function. - ``state_machine`` is the state machine which controls the state which called the directive function. - ``reporter`` is the state machine's `reporter` instance. Directive functions return a list of nodes which will be inserted into the document tree at the point where the directive was encountered. This can be an empty list if there is nothing to insert. For ordinary directives, the list must contain body elements or structural elements. Some directives are intended specifically for substitution definitions, and must return a list of `Text` nodes and/or inline elements (suitable for inline insertion, in place of the substitution reference). Such directives must verify substitution definition context, typically using code like this:: if not isinstance(state, states.SubstitutionDef): error = self.reporter.error( 'Invalid context: the "%s" directive can only be used ' 'within a substitution definition.' % (name), nodes.literal_block(block_text, block_text), line=lineno) return [error] rFNc ||_||_||_||_||_||_||_||_| |_| j |_ dSr/) name argumentsoptionscontentlinenocontent_offset block_textstate state_machiner@) r)rkrlrmrnrorprqrrrss r+r,zDirective.__init__?sQ "   ,$ *%. r-c td)Nz Must override run() in subclass.)NotImplementedErrorr)s r+rIz Directive.runLs!"DEEEr-c"t||S)a Return a DirectiveError suitable for being thrown as an exception. Call "raise self.directive_error(level, message)" from within a directive implementation to return one single system message at level `level`, which automatically gets the directive block and the line number added. Preferably use the `debug`, `info`, `warning`, `error`, or `severe` wrapper methods, e.g. ``self.error(message)`` to generate an ERROR-level directive error. )r`res r+directive_errorzDirective.directive_errorQseW---r-c.|d|S)Nrrxr)rfs r+r7zDirective.debug`##Aw///r-c.|d|S)Nr9rzr{s r+infozDirective.infocr|r-c.|d|S)Nrzr{s r+warningzDirective.warningfr|r-c.|d|S)Nrzr{s r+rHzDirective.errorir|r-c.|d|S)Nrzr{s r+severezDirective.severelr|r-cN|js|d|jzdS)ze Throw an ERROR-level DirectiveError if the directive doesn't have contents. z:Content block expected for the "%s" directive; none found.N)rnrHrkrvs r+assert_has_contentzDirective.assert_has_contentqs= | 8**+-1Y788 8 8 8r-cd|jvrptj|jd}d|vr|d=|d||jj||dSdS)zAppend self.options['name'] to node['names'] if it exists.
