This is the Docutils (Python Documentation Utilities) package.
__init__.py: Contains component base classes, exception classes, and Docutils version information.
core.py: Contains the
Publisher class and
frontend.py: Runtime settings (command-line interface, configuration files) processing, for Docutils front-ends.
io.py: Provides a uniform API for low-level input and output.
nodes.py: Docutils document tree (doctree) node class library.
statemachine.py: A finite state machine specialized for regular-expression-based text filters.
languages: Language-specific mappings of terms.
parsers: Syntax-specific input parser modules or packages.
readers: Context-specific input handlers which understand the data source and manage a parser.
transforms: Modules used by readers and writers to modify DPS doctrees.
utils: Contains the
Reporter system warning class and miscellaneous
utilities used by readers, writers, and transforms.
utils/urischemes.py: Contains a complete mapping of known URI addressing scheme names to descriptions.
utils/math: Contains functions for conversion of mathematical notation between different formats (LaTeX, MathML, text, …).
writers: Format-specific output translators.
Base class for Docutils components.
Name of the component type (‘reader’, ‘parser’, ‘writer’). Override in subclasses.
Names for this component. Override in subclasses.
Is format supported by this component?
To be used by transforms to ask the dependent component if it supports a certain input context or output format.
Runtime setting specification base class.
SettingsSpec subclass objects used by docutils.frontend.OptionParser.
The name of the config file section specific to this component (lowercase, no brackets). Override in subclasses.
A list of names of config file sections that are to be applied before config_section, in order (from general to specific). In other words, the settings in config_section are to be overlaid on top of the settings from these sections. The “general” section is assumed implicitly. Override in subclasses.
Settings containing filesystem paths. Override in subclasses. Settings listed here are to be interpreted relative to the current working directory.
A dictionary of auxiliary defaults, to override defaults for settings defined in other components. Override in subclasses.
A dictionary of defaults for settings not in settings_spec (internal settings, intended to be inaccessible by command-line and config file). Override in subclasses.
Runtime settings specification. Override in subclasses.
Defines runtime settings and associated command-line options, as used by docutils.frontend.OptionParser. This is a tuple of:
Option group title (string or None which implies no group, just a list of single options).
Description (string or None).
A sequence of option tuples. Each consists of:
Help text (string)
List of option strings (e.g.
Dictionary of keyword arguments sent to the OptionParser/OptionGroup
Runtime setting names are derived implicitly from long option names
settings.a_setting) or explicitly from the
‘dest’ keyword argument.
Most settings will also have a ‘validator’ keyword & function. The
validator function validates setting values (from configuration files
and command-line option arguments) and converts them to appropriate
types. For example, the
function, required by all boolean settings, converts true values
(‘1’, ‘on’, ‘yes’, and ‘true’) to 1 and false values (‘0’, ‘off’,
‘no’, ‘false’, and ‘’) to 0. Validators need only be set once per
setting. See the docutils.frontend.validate_* functions.
See the optparse docs for more details.
More triples of group title, description, options, as many times as needed. Thus, settings_spec tuples can be simply concatenated.
Runtime transform specification base class.
TransformSpec subclass objects used by docutils.transforms.Transformer.
Transforms required by this class. Override in subclasses.
List of functions to try to resolve unknown references. Unknown references have a ‘refname’ attribute which doesn’t correspond to any target in the document. Called when the transforms in docutils.tranforms.references are unable to find a correct target. The list should contain functions which will try to resolve unknown references, with the following signature:
def reference_resolver(node): '''Returns boolean: true if resolved, false if not.'''
If the function is able to resolve the reference, it should also remove the ‘refname’ attribute and mark the node as resolved:
del node['refname'] node.resolved = 1
Each function must have a “priority” attribute which will affect the order the unknown_reference_resolvers are run:
reference_resolver.priority = 100
Override in subclasses.
Abstract base class of nodes in a document tree.
Traverse a tree of Node objects, calling the dispatch_visit() method of visitor when entering each node. (The walkabout() method is similar, except it also calls the dispatch_departure() method before exiting each node.)
This tree traversal supports limited in-place tree modifications. Replacing one node with one or more nodes is OK, as is removing an element. However, if the node removed or replaced occurs after the current node, the old node will still be traversed, and any new nodes will not.
visit methods (and
depart methods for
walkabout()), TreePruningException subclasses may be raised
(SkipChildren, SkipSiblings, SkipNode, SkipDeparture).
Parameter visitor: A NodeVisitor object, containing a
visit implementation for each Node subclass encountered.
Return true if we should stop the traversal.
Escape string values that are elements of a list, for serialization.
