Each directive requires one or more signatures to provide basic -information about what is being described, and the content should be the -description. The basic version makes entries in the general index; if no index -entry is desired, you can give the directive option flag ``:noindex:``. The -following example shows all of the features of this directive type:: - - .. function:: spam(eggs) - ham(eggs) - :noindex: - - Spam or ham the foo. - -The signatures of object methods or data attributes should not include the -class name, but be nested in a class directive. The generated files will -reflect this nesting, and the target identifiers (for HTML output) will use -both the class and method name, to enable consistent cross-references. If you -describe methods belonging to an abstract protocol such as context managers, -use a class directive with a (pseudo-)type name too to make the -index entries more informative. - -The directives are: - -.. describe:: c:function - - Describes a C function. The signature should be given as in C, e.g.:: - - .. c:function:: PyObject* PyType_GenericAlloc(PyTypeObject *type, Py_ssize_t nitems) - - This is also used to describe function-like preprocessor macros. The names - of the arguments should be given so they may be used in the description. - - Note that you don't have to backslash-escape asterisks in the signature, - as it is not parsed by the reST inliner. - -.. describe:: c:member - - Describes a C struct member. Example signature:: - - .. c:member:: PyObject* PyTypeObject.tp_bases - - The text of the description should include the range of values allowed, how - the value should be interpreted, and whether the value can be changed. - References to structure members in text should use the ``member`` role. - -.. describe:: c:macro - - Describes a "simple" C macro. Simple macros are macros which are used - for code expansion, but which do not take arguments so cannot be described as - functions. This is not to be used for simple constant definitions. Examples - of its use in the Python documentation include :c:macro:`PyObject_HEAD` and - :c:macro:`Py_BEGIN_ALLOW_THREADS`. - -.. describe:: c:type - - Describes a C type. The signature should just be the type name. - -.. describe:: c:var - - Describes a global C variable. The signature should include the type, such - as:: - - .. cvar:: PyObject* PyClass_Type - -.. describe:: data - - Describes global data in a module, including both variables and values used - as "defined constants." Class and object attributes are not documented - using this directive. - -.. describe:: exception - - Describes an exception class. The signature can, but need not include - parentheses with constructor arguments. - -.. describe:: function - - Describes a module-level function. The signature should include the - parameters, enclosing optional parameters in brackets. Default values can be - given if it enhances clarity. For example:: - - .. function:: repeat([repeat=3[, number=1000000]]) - - Object methods are not documented using this directive. Bound object methods - placed in the module namespace as part of the public interface of the module - are documented using this, as they are equivalent to normal functions for - most purposes. - - The description should include information about the parameters required and - how they are used (especially whether mutable objects passed as parameters - are modified), side effects, and possible exceptions. A small example may be - provided. - -.. describe:: decorator - - Describes a decorator function. The signature should *not* represent the - signature of the actual function, but the usage as a decorator. For example, - given the functions - - .. code-block:: python - - def removename(func): - func.__name__ = '' - return func - - def setnewname(name): - def decorator(func): - func.__name__ = name - return func - return decorator - - the descriptions should look like this:: - - .. decorator:: removename - - Remove name of the decorated function. - - .. decorator:: setnewname(name) - - Set name of the decorated function to *name*. - - There is no ``deco`` role to link to a decorator that is marked up with - this directive; rather, use the ``:func:`` role. - -.. describe:: class - - Describes a class. The signature can include parentheses with parameters - which will be shown as the constructor arguments. - -.. describe:: attribute - - Describes an object data attribute. The description should include - information about the type of the data to be expected and whether it may be - changed directly. This directive should be nested in a class directive, - like in this example:: - - .. class:: Spam - - Description of the class. - - .. data:: ham - - Description of the attribute. - - If is also possible to document an attribute outside of a class directive, - for example if the documentation for different attributes and methods is - split in multiple sections. The class name should then be included - explicitly:: - - .. data:: Spam.eggs - -.. describe:: method - - Describes an object method. The parameters should not include the ``self`` - parameter. The description should include similar information to that - described for ``function``. This directive should be nested in a class - directive, like in the example above. - -.. describe:: decoratormethod - - Same as ``decorator``, but for decorators that are methods. - - Refer to a decorator method using the ``:meth:`` role. - -.. describe:: opcode - - Describes a Python :term:`bytecode` instruction. - -.. describe:: cmdoption - - Describes a Python command line option or switch. Option argument names - should be enclosed in angle brackets. Example:: - - .. cmdoption:: -m - - Run a module as a script. - -.. describe:: envvar - - Describes an environment variable that Python uses or defines. - - -There is also a generic version of these directives: - -.. describe:: describe - - This directive produces the same formatting as the specific ones explained - above but does not create index entries or cross-referencing targets.

The file may be included using the -``literalinclude`` directive. [1]_ For example, to include the Python source file -:file:`example.py`, use:: - - .. literalinclude:: example.py - -The file name is relative to the current file's path. Documentation-specific -include files should be placed in the ``Doc/includes`` subdirectory. - - -Inline markup -------------- - -As said before, Sphinx uses interpreted text roles to insert semantic markup in -documents. - -Names of local variables, such as function/method arguments, are an exception, -they should be marked simply with ``*var*``. - -For all other roles, you have to write ``:rolename:`content```. - -There are some additional facilities that make cross-referencing roles more -versatile: - -* You may supply an explicit title and reference target, like in reST direct - hyperlinks: ``:role:`title ``` will refer to *target*, but the link - text will be *title*. - -* If you prefix the content with ``!``, no reference/hyperlink will be created. - -* For the Python object roles, if you prefix the content with ``~``, the link - text will only be the last component of the target. For example, - ``:meth:`~Queue.Queue.get``` will refer to ``Queue.Queue.get`` but only - display ``get`` as the link text. - - In HTML output, the link's ``title`` attribute (that is e.g. shown as a - tool-tip on mouse-hover) will always be the full target name. - -The following roles refer to objects in modules and are possibly hyperlinked if -a matching identifier is found: - -.. describe:: mod - - The name of a module; a dotted name may be used. This should also be used for - package names. - -.. describe:: func - - The name of a Python function; dotted names may be used. The role text - should not include trailing parentheses to enhance readability. The - parentheses are stripped when searching for identifiers. - -.. describe:: data - - The name of a module-level variable or constant. - -.. describe:: const - - The name of a "defined" constant. This may be a C-language ``#define`` - or a Python variable that is not intended to be changed. - -.. describe:: class - - A class name; a dotted name may be used. - -.. describe:: meth - - The name of a method of an object. The role text should include the type - name and the method name. A dotted name may be used. - -.. describe:: attr - - The name of a data attribute of an object. - -.. describe:: exc - - The name of an exception. A dotted name may be used. - -The name enclosed in this markup can include a module name and/or a class name. -For example, ``:func:`filter``` could refer to a function named ``filter`` in -the current module, or the built-in function of that name. In contrast, -``:func:`foo.filter``` clearly refers to the ``filter`` function in the ``foo`` -module. - -Normally, names in these roles are searched first without any further -qualification, then with the current module name prepended, then with the -current module and class name (if any) prepended. If you prefix the name with a -dot, this order is reversed. For example, in the documentation of the -:mod:`codecs` module, ``:func:`open``` always refers to the built-in function, -while ``:func:`.open``` refers to :func:`codecs.open`. - -A similar heuristic is used to determine whether the name is an attribute of -the currently documented class. - -The following roles create cross-references to C-language constructs if they -are defined in the API documentation: - -.. describe:: c:data - - The name of a C-language variable. - -.. describe:: c:func - - The name of a C-language function. Should include trailing parentheses. - -.. describe:: c:macro - - The name of a "simple" C macro, as defined above. - -.. describe:: c:type - - The name of a C-language type. - -.. describe:: c:member - - The name of a C type member, as defined above. - - -The following role does possibly create a cross-reference, but does not refer -to objects: - -.. describe:: token - - The name of a grammar token (used in the reference manual to create links - between production displays). - - -The following role creates a cross-reference to the term in the glossary: - -.. describe:: term - - Reference to a term in the glossary. The glossary is created using the - ``glossary`` directive containing a definition list with terms and - definitions. It does not have to be in the same file as the ``term`` - markup, in fact, by default the Python docs have one global glossary - in the ``glossary.rst`` file. - - If you use a term that's not explained in a glossary, you'll get a warning - during build. - ---------- - -The following roles don't do anything special except formatting the text -in a different style: - -.. describe:: command - - The name of an OS-level command, such as ``rm``. - -.. describe:: dfn - - Mark the defining instance of a term in the text. (No index entries are - generated.) - -.. describe:: envvar - - An environment variable. Index entries are generated. - -.. describe:: file - - The name of a file or directory. Within the contents, you can use curly - braces to indicate a "variable" part, for example:: - - ... is installed in :file:`/usr/lib/python2.{x}/site-packages` ... - - In the built documentation, the ``x`` will be displayed differently to - indicate that it is to be replaced by the Python minor version. - -.. describe:: guilabel - - Labels presented as part of an interactive user interface should be marked - using ``guilabel``. This includes labels from text-based interfaces such as - those created using :mod:`curses` or other text-based libraries. Any label - used in the interface should be marked with this role, including button - labels, window titles, field names, menu and menu selection names, and even - values in selection lists. - -.. describe:: kbd - - Mark a sequence of keystrokes. What form the key sequence takes may depend - on platform- or application-specific conventions. When there are no relevant - conventions, the names of modifier keys should be spelled out, to improve - accessibility for new users and non-native speakers. For example, an - *xemacs* key sequence may be marked like ``:kbd:`C-x C-f```, but without - reference to a specific application or platform, the same sequence should be - marked as ``:kbd:`Control-x Control-f```. - -.. describe:: keyword - - The name of a Python keyword. Using this role will generate a link to the - documentation of the keyword. ``True``, ``False`` and ``None`` do not use - this role, but simple code markup (````True````), given that they're - fundamental to the language and should be known to any programmer. - -.. describe:: mailheader - - The name of an RFC 822-style mail header. This markup does not imply that - the header is being used in an email message, but can be used to refer to any - header of the same "style." This is also used for headers defined by the - various MIME specifications.

This is - used to mark a complete sequence of menu selections, including selecting - submenus and choosing a specific operation, or any subsequence of such a - sequence. The names of individual selections should be separated by - ``-->``. - - For example, to mark the selection "Start > Programs", use this markup:: - - :menuselection:`Start --> Programs` - - When including a selection that includes some trailing indicator, such as the - ellipsis some operating systems use to indicate that the command opens a - dialog, the indicator should be omitted from the selection name. - -.. describe:: mimetype - - The name of a MIME type, or a component of a MIME type (the major or minor - portion, taken alone). - -.. describe:: newsgroup - - The name of a Usenet newsgroup. - -.. describe:: option - - A command-line option of Python. The leading hyphen(s) must be included. - If a matching ``cmdoption`` directive exists, it is linked to.

The content of - the directive should be written in complete sentences and include all - appropriate punctuation. - - Example:: - - .. note:: - - This function is not suitable for sending spam e-mails. - -.. describe:: warning - - An important bit of information about an API that a user should be aware of - when using whatever bit of API the warning pertains to. The content of the - directive should be written in complete sentences and include all appropriate - punctuation. In the interest of not scaring users away from pages filled - with warnings, this directive should only be chosen over ``note`` for - information regarding the possibility of crashes, data loss, or security - implications. - -.. describe:: versionadded - - This directive documents the version of Python which added the described - feature to the library or C API. When this applies to an entire module, it - should be placed at the top of the module section before any prose. - - The first argument must be given and is the version in question; you can add - a second argument consisting of a *brief* explanation of the change. - - Example:: - - .. versionadded:: 3.1 - The *spam* parameter. - - Note that there must be no blank line between the directive head and the - explanation; this is to make these blocks visually continuous in the markup. - -.. describe:: versionchanged - - Similar to ``versionadded``, but describes when and what changed in the named - feature in some way (new parameters, changed side effects, etc.). - --------------- - -.. describe:: impl-detail - - This directive is used to mark CPython-specific information. Use either with - a block content or a single sentence as an argument, i.e. either :: - - .. impl-detail:: - - This describes some implementation detail. - - More explanation. - - or :: - - .. impl-detail:: This shortly mentions an implementation detail. - - "\ **CPython implementation detail:**\ " is automatically prepended to the - content. - -.. describe:: seealso - - Many sections include a list of references to module documentation or - external documents. These lists are created using the ``seealso`` directive. - - The ``seealso`` directive is typically placed in a section just before any - sub-sections. For the HTML output, it is shown boxed off from the main flow - of the text. - - The content of the ``seealso`` directive should be a reST definition list. - Example:: - - .. seealso:: - - Module :mod:`zipfile` - Documentation of the :mod:`zipfile` standard module. - - `GNU tar manual, Basic Tar Format `_ - Documentation for tar archive files, including GNU tar extensions. - -.. describe:: rubric - - This directive creates a paragraph heading that is not used to create a - table of contents node. It is currently used for the "Footnotes" caption. - -.. describe:: centered - - This directive creates a centered boldfaced paragraph. Use it as follows:: - - .. centered:: - - Paragraph contents. - - -Table-of-contents markup ------------------------- - -Since reST does not have facilities to interconnect several documents, or split -documents into multiple output files, Sphinx uses a custom directive to add -relations between the single files the documentation is made of, as well as -tables of contents. The ``toctree`` directive is the central element. - -.. describe:: toctree - - This directive inserts a "TOC tree" at the current location, using the - individual TOCs (including "sub-TOC trees") of the files given in the - directive body. A numeric ``maxdepth`` option may be given to indicate the - depth of the tree; by default, all levels are included. - - Consider this example (taken from the library reference index):: - - .. toctree:: - :maxdepth: 2 - - intro - strings - datatypes - numeric - (many more files listed here) - - This accomplishes two things: - - * Tables of contents from all those files are inserted, with a maximum depth - of two, that means one nested heading. ``toctree`` directives in those - files are also taken into account. - * Sphinx knows that the relative order of the files ``intro``, - ``strings`` and so forth, and it knows that they are children of the - shown file, the library index. From this information it generates "next - chapter", "previous chapter" and "parent chapter" links. - - In the end, all files included in the build process must occur in one - ``toctree`` directive; Sphinx will emit a warning if it finds a file that is - not included, because that means that this file will not be reachable through - standard navigation. - - The special file ``contents.rst`` at the root of the source directory is the - "root" of the TOC tree hierarchy; from it the "Contents" page is generated. - - -Index-generating markup ------------------------ - -Sphinx automatically creates index entries from all information units (like -functions, classes or attributes) like discussed before. - -However, there is also an explicit directive available, to make the index more -comprehensive and enable index entries in documents where information is not -mainly contained in information units, such as the language reference. - -The directive is ``index`` and contains one or more index entries. Each entry -consists of a type and a value, separated by a colon. - -For example:: - - .. index:: - single: execution; context - module: __main__ - module: sys - triple: module; search; path - -This directive contains five entries, which will be converted to entries in the -generated index which link to the exact location of the index statement (or, in -case of offline media, the corresponding page number). - -The possible entry types are: - -single - Creates a single index entry. Can be made a subentry by separating the - subentry text with a semicolon (this notation is also used below to describe - what entries are created). -pair - ``pair: loop; statement`` is a shortcut that creates two index entries, - namely ``loop; statement`` and ``statement; loop``. -triple - Likewise, ``triple: module; search; path`` is a shortcut that creates three - index entries, which are ``module; search path``, ``search; path, module`` and - ``path; module search``. -module, keyword, operator, object, exception, statement, builtin - These all create two index entries. For example, ``module: hashlib`` creates - the entries ``module; hashlib`` and ``hashlib; module``. - -For index directives containing only "single" entries, there is a shorthand -notation:: - - .. index:: BNF, grammar, syntax, notation - -This creates four index entries. - - -Grammar production displays ---------------------------- - -Special markup is available for displaying the productions of a formal grammar. -The markup is simple and does not attempt to model all aspects of BNF (or any -derived forms), but provides enough to allow context-free grammars to be -displayed in a way that causes uses of a symbol to be rendered as hyperlinks to -the definition of the symbol. There is this directive: - -.. describe:: productionlist - - This directive is used to enclose a group of productions. Each production is - given on a single line and consists of a name, separated by a colon from the - following definition. If the definition spans multiple lines, each - continuation line must begin with a colon placed at the same column as in the - first line. - - Blank lines are not allowed within ``productionlist`` directive arguments. - - The definition can contain token names which are marked as interpreted text - (e.g. ``unaryneg ::= "-" `integer```) -- this generates cross-references - to the productions of these tokens. - - Note that no further reST parsing is done in the production, so that you - don't have to escape ``*`` or ``|`` characters. - - -..

In this - case, the description should be capitalized as a stand-alone - sentence. - -Many special names are used in the Python documentation, including the names of -operating systems, programming languages, standards bodies, and the like. Most -of these entities are not assigned any special markup, but the preferred -spellings are given here to aid authors in maintaining the consistency of -presentation in the Python documentation. - -Other terms and words deserve special mention as well; these conventions should -be used to ensure consistency throughout the documentation: - -CPU - For "central processing unit."

When spelled out, it is - always one word and both forms start with a lower case 'r'. - -Unicode - The name of a character coding system. This is always written - capitalized. - -Unix - The name of the operating system developed at AT&T Bell Labs in the early - 1970s. - -Affirmative Tone ----------------- - -The documentation focuses on affirmatively stating what the language does and -how to use it effectively. - -Except for certain security risks or segfault risks, the docs should avoid -wording along the lines of "feature x is dangerous" or "experts only". These -kinds of value judgments belong in external blogs and wikis, not in the core -documentation. - -Bad example (creating worry in the mind of a reader): - - Warning: failing to explicitly close a file could result in lost data or - excessive resource consumption. Never rely on reference counting to - automatically close a file. - -Good example (establishing confident knowledge in the effective use of the language): - - A best practice for using files is use a try/finally pair to explicitly - close a file after it is used. Alternatively, using a with-statement can - achieve the same effect. This assures that files are flushed and file - descriptor resources are released in a timely manner. - -Economy of Expression ---------------------- - -More documentation is not necessarily better documentation. Err on the side -of being succinct. - -It is an unfortunate fact that making documentation longer can be an impediment -to understanding and can result in even more ways to misread or misinterpret the -text. Long descriptions full of corner cases and caveats can create the -impression that a function is more complex or harder to use than it actually is. - -The documentation for :func:`super` is an example of where a good deal of -information was condensed into a few short paragraphs. Discussion of -:func:`super` could have filled a chapter in a book, but it is often easier to -grasp a terse description than a lengthy narrative. - - -Code Examples -------------- - -Short code examples can be a useful adjunct to understanding. Readers can often -grasp a simple example more quickly than they can digest a formal description in -prose. - -People learn faster with concrete, motivating examples that match the context of -a typical use case. For instance, the :func:`str.rpartition` method is better -demonstrated with an example splitting the domain from a URL than it would be -with an example of removing the last word from a line of Monty Python dialog. - -The ellipsis for the :attr:`sys.ps2` secondary interpreter prompt should only be -used sparingly, where it is necessary to clearly differentiate between input -lines and output lines. Besides contributing visual clutter, it makes it -difficult for readers to cut-and-paste examples so they can experiment with -variations. - -Code Equivalents ----------------- - -Giving pure Python code equivalents (or approximate equivalents) can be a useful -adjunct to a prose description. A documenter should carefully weigh whether the -code equivalent adds value. - -A good example is the code equivalent for :func:`all`. The short 4-line code -equivalent is easily digested; it re-emphasizes the early-out behavior; and it -clarifies the handling of the corner-case where the iterable is empty. In -addition, it serves as a model for people wanting to implement a commonly -requested alternative where :func:`all` would return the specific object -evaluating to False whenever the function terminates early. - -A more questionable example is the code for :func:`itertools.groupby`. Its code -equivalent borders on being too complex to be a quick aid to understanding. -Despite its complexity, the code equivalent was kept because it serves as a -model to alternative implementations and because the operation of the "grouper" -is more easily shown in code than in English prose. - -An example of when not to use a code equivalent is for the :func:`oct` function. -The exact steps in converting a number to octal doesn't add value for a user -trying to learn what the function does. - -Audience --------- - -The tone of the tutorial (and all the docs) needs to be respectful of the -reader's intelligence. Don't presume that the readers are stupid. Lay out the -relevant information, show motivating use cases, provide glossary links, and do -your best to connect-the-dots, but don't talk down to them or waste their time. - -The tutorial is meant for newcomers, many of whom will be using the tutorial to -evaluate the language as a whole.
