Sage autodoc extension#

This is sphinx.ext.autodoc extension modified for Sage objects.

The original header of sphinx.ext.autodoc:

Extension to create automatic documentation from code docstrings.

Automatically insert docstrings for functions, classes or whole modules into the doctree, thus avoiding duplication between docstrings and documentation for those who like elaborate docstrings.

This module is currently based on sphinx.ext.autodoc from Sphinx version 5.3.0. Compare against the upstream original source file sphinx/ext/autodoc/__init__.py.

In the source file of this module, major modifications are delimited by a pair of comment dividers. To lessen maintenance burden, we aim at reducing the modifications.

AUTHORS:

? (before 2011): initial version derived from sphinx.ext.autodoc
Johan S. R. Nielsen: support for _sage_argspec_
Simon King (2011-04): use sageinspect; include public cython attributes only in the documentation if they have a docstring
Kwankyu Lee (2018-12-26, 2022-11-08): rebased on the latest sphinx.ext.autodoc

class sage_docbuild.ext.sage_autodoc.Documenter(directive: DocumenterBridge, name: str, indent: str = '')#

Bases: object

A Documenter knows how to autodocument a single object type. When registered with the AutoDirective, it will be used to document objects of that type when needed by autodoc.

Its objtype attribute selects what auto directive it is assigned to (the directive name is ‘auto’ + objtype), and what directive it generates by default, though that can be overridden by an attribute called directivetype.

A Documenter has an option_spec that works like a docutils directive’s; in fact, it will be used to parse an auto directive’s options that matches the Documenter.

add_content(more_content)#: Add content from docstrings, attribute documentation and user.

add_directive_header(sig)#: Add the directive header and options to the generated content.

add_line(line, source, *lineno)#: Append one line of generated reST to the output.

classmethod can_document_member(member, membername, isattr, parent)#: Called to see if a member can be documented by this Documenter.

check_module()#: Check if self.object is really defined in the module given by self.modname.

content_indent = ' '#: indentation by which to indent the directive content

document_members(all_members=False)#

Generate reST for member documentation.

If all_members is True, document all members, else those given by self.options.members.

property documenters: Dict[str, Type[Documenter]]#: Returns registered Documenter classes

filter_members(members, want_all)#

Filter the given member list.

Members are skipped if

they are private (except if given explicitly or the private-members option is set)
they are special methods (except if given explicitly or the special-members option is set)
they are undocumented (except if the undoc-members option is set)

The user can override the skipping decision by connecting to the autodoc-skip-member event.

format_args(**kwargs)#

Format the argument signature of self.object.

Should return None if the object does not have a signature.

format_name()#

Format the name of self.object.

This normally should be something that can be parsed by the generated directive, but doesn’t need to be (Sphinx will display it unparsed then).

format_signature(**kwargs)#

Format the signature (arguments and return annotation) of the object.

Let the user process it via the autodoc-process-signature event.

generate(more_content=None, real_modname=None, check_module=False, all_members=False)#

Generate reST for the object given by self.name, and possibly for its members.

If more_content is given, include that content. If real_modname is given, use that module name to find attribute docs. If check_module is True, only generate if the object is defined in the module name it is imported from. If all_members is True, document all members.

get_attr(obj, name, *defargs)#: getattr() override for types such as Zope interfaces.

get_doc()#

Decode and return lines of the docstring(s) for the object.

When it returns None, autodoc-process-docstring will not be called for this object.

get_object_members(want_all)#

Return (members_check_module, members) where members is a list of (membername, member) pairs of the members of self.object.

If want_all is True, return all members. Else, only return those members given by self.options.members (which may also be None).

get_real_modname()#

Get the real module name of an object to document.

It can differ from the name of the module through which the object was imported.

get_sourcename()#

import_object(raiseerror=False)#

Import the object given by self.modname and self.objpath and set it as self.object.

Returns True if successful, False if an error occurred.

member_order = 0#: order if autodoc_member_order is set to ‘groupwise’

objtype = 'object'#: name by which the directive is called (auto…) and the default generated directive name

option_spec: Dict[str, Callable[[str], Any]] = {'noindex': <function bool_option>}#

parse_name()#

Determine what module to import and what attribute to document.

Returns True and sets self.modname, self.objpath, self.fullname, self.args and self.retann if parsing and resolving was successful.

priority = 0#: priority if multiple documenters return True from can_document_member

process_doc(docstrings)#: Let the user process the docstrings before adding them.

resolve_name(modname, parents, path, base)#

Resolve the module and name of the object to document given by the arguments and the current module/class.

Must return a pair of the module name and a chain of attributes; for example, it would return ('zipfile', ['ZipFile', 'open']) for the zipfile.ZipFile.open method.

sort_members(documenters, order)#: Sort the given member list.

titles_allowed = False#: true if the generated content may contain titles

sage_docbuild.ext.sage_autodoc.between(marker, what=None, keepempty=False, exclude=False)#

Return a listener that either keeps, or if exclude is True excludes, lines between lines that match the marker regular expression. If no line matches, the resulting docstring would be empty, so no change will be made unless keepempty is true.

If what is a sequence of strings, only docstrings of a type in what will be processed.

Use like this (e.g. in the setup() function of conf.py):

from sphinx.ext.autodoc import cut_lines
app.connect('autodoc-process-docstring', cut_lines(4, what=['module']))

This can (and should) be used in place of automodule_skip_lines.
