Future changes
==============

Command line interface
----------------------

* The _`command-line usage pattern` will change:

  .. code:: diff

       - COMMAND [OPTIONS] [SOURCE [DESTINATION]]
       + COMMAND [OPTIONS] [SOURCE [SOURCE2 [...]]] [>DESTINATION]

  * Remove short options ``-i`` and ``-o`` in Docutils 0.22.
    Use the long equivalents ``--input-encoding`` and ``--output-encoding``.

  * Stop accepting the DESTINATION positional argument in Docutils 1.0.
    Use output redirection or the option ``--output=DESTINATION``
    (available since Docutils 0.20).

  * Accept more than one source document and the short option
    ``-o`` for ``--output`` in Docutils 2.0

  For the rationale, see https://clig.dev/#arguments-and-flags.

.. _entry points:
    https://packaging.python.org/en/latest/specifications/entry-points/


Document Tree / Docutils DTD
----------------------------

* Do not lowercase reference names in the `refname attribute`_
  (matching hyperlinks, footnotes, and citations remains case insensitive),
  and drop the ``name`` attribute from <reference> nodes
  in Docutils 1.0.

.. _refname attribute: docs/ref/doctree.html#refname

`Input encoding`_
-----------------

* Change the default input encoding from ``None`` (auto-detect) to
  "utf-8" in Docutils 0.22.

* Remove the input encoding auto-detection code in Docutils 1.0 or later.

Writers
-------

* The `default HTML writer`__  will change in Docutils 2.0:

  The rst2html_ front end and ``get_writer_by_name('html')`` select
  "html4css1" now and will select "html5" in Docutils 2.0 and later.

  - Use rst2html4_, ``docutils --writer=html4``, or
    ``get_writer_by_name('html4')`` if you depend on stability of the
    generated HTML code, e.g. because you use a custom style sheet or
    post-processing that may break otherwise.
  - Use rst2html5_, ``docutils`` or ``get_writer_by_name('html5')``
    if you want a HTML5 document.

  __ docs/user/html.html#html

* "html5" writer:

  - Move attribution behind the blockquote to comply with the `"living
    standard"`__. (HTML5__ allows <cite> elements inside a blockquote.)

    __ https://html.spec.whatwg.org/#the-blockquote-element
    __ https://www.w3.org/TR/2014/REC-html5-20141028/grouping-content.html
       #the-blockquote-element

  - Change the default value for math_output_ to "MathML"
    in Docutils 0.22.

  - Unitless image_ :width: and :hight: values and dimensions
    read from the image due to a :scale: option will be written as
    "width" and "hight" attributes instead of "style" rules to allow
    specification of the aspect ratio to `prevent jank when loading
    images`__ without overwriting an image size set in a CSS stylesheet
    in Docutils 0.22 (cf.  `feature-requests:102`__).
    The current behaviour is kept for dimensions with value, so
    users may specify, e.g. ``:width: 50px`` instead of ``:width: 50``
    to override CSS stylesheet rules.

    __ https://developer.mozilla.org/en-US/docs/Learn/Performance/Multimedia
       #rendering_strategy_preventing_jank_when_loading_images
    __ https://sourceforge.net/p/docutils/feature-requests/102/

  - Change the default value of the initial_header_level_ setting to None
    (<h2> if there is a document title, else <h1>) in Docutils 1.0.

  - Remove option ``--embed-images`` (obsoleted by "image_loading_")
    in Docutils 2.0.

* "latex2e" writer:

  - Change default of use_latex_citations_ setting to True
    in Docutils 1.0.

  - Change default of legacy_column_widths_ setting to False
    in Docutils 1.0.

  - Remove ``use_verbatim_when_possible`` setting
    (use literal_block_env_: verbatim) in Docutils 2.0.

  - Don't wrap references with custom reference-label_ in
    a ``\hyperref`` command in Docutils 0.22.
    Specify, e.g., "ref" instead of "ref*" to keep generating hyperlinks.

    .. _reference-label: docs/user/config.html#reference-label

* "null" writer: output will change to the empty string
  in Docutils 0.22.

* "manpage" writer:

  - No more changing case in to uppercase, leave it to the source.


Misc
----

* Document tree:
  Allow multiple <term> elements in a <definition_list_item>
  in Docutils 0.22 (cf. `feature-requests:60`__).
  Third-party writers may need adaption.

  __ https://sourceforge.net/p/docutils/feature-requests/60/

* Remove `parsers.rst.directives.CSVTable.HeaderDialect`
  in Docutils 0.22.

* Remove the "rawsource" argument from `nodes.Text.__init__()`
  in Docutils 2.0.

* Drop support for `old-format configuration files`_ in Docutils 2.0.

* Remove the ``--html-writer`` option of the `buildhtml.py`_ application
  (obsoleted by the `"writer" setting`_ since Docutils 0.18)
  in Docutils 2.0.

* Revise the `String I/O`__ interface used by the `publish_string()`
  and `publish_from_doctree()` publisher convenience functions.
  (In Python 3, name and behaviour no longer match.)

  __ docs/api/publisher.html#string-i-o

* Move math format conversion from docutils/utils/math (called from
  docutils/writers/_html_base.py) to a transform__.

  __ docs/ref/transforms.html

* Remove mistranslated localizations of the "admonition" directive name in
  Docutils 0.22.

  Use the English term, matching translations introduced in Docutils 0.21,
  or specific admonitions instead of "aanmaning" (nl),
  "admonition" (fr), "ammonizione" (it), "ermahnung" (de),
  "exhortación" (es), "formaning" (da), "sciigo" (eo),
  "upomnienie" (pl), "vermaning" (af),
  to avoid errors in future conversions.

Release 0.21.2b.dev (unpublished)
=================================

Post-release waiting.


Release 0.21.1 (2024-04-10)
===========================

The sdist in 0.21 was incomplete

- pypi allows no file replacing
- adding a postrelease suffix "post1": docutils-0.21.post1.tar.gz
  works on pypi, but fails with pip because the metadata differs.

  But if the metadata is 0.21.post1 pypi makes it a new release.

  0.21.1 is the same code except for the version number.


Release 0.21 (2024-04-09)
=========================

* General:

  - Drop support for Python 3.7 and 3.8.

  - Provide ``rst2*`` "console_scripts" `entry points`_
    (without the ``.py`` extension) instead of installing the
    ``rst2*.py`` `front end tools`_ in the binary PATH. [#]_

    Exceptions: ``rstpep2html.py`` and ``rst2odt_prepstyles.py``:

    - Use ``docutils --reader=pep --writer=pep_html`` for a PEP preview. [#]_
    - Use ``python -m docutils.writers.odf_odt.prepstyles``
      to `strip the page size`__ from an ODT writer stylesheet.

    __ docs/user/odt.html#page-size

  .. [#] Some Linux distributions already use the short names.
  .. [#] The final rendering is done by a Sphinx-based build system
         (cf. :PEP:`676`).

* reStructuredText:

  - Use the same CSV format for the ``:header:`` option and the main data
    of the "csv-table_" directive.

  - New option "loading" for the `"image" directive`_.
    Sets the new attribute loading__ of the <image> doctree element.

  __ docs/ref/doctree.html#loading

* Configuration changes:

  - New configuration setting root_prefix_.
    Configurable root directory for included files.

  - New configuration setting sources_ for the "buildhtml.py" application.

  - Simpler and more secure `input encoding`_ default behaviour:

    Do not use the locale encoding as fallback if Python is started in
    `UTF-8 mode`_. Stop using "latin1" as second fallback.

    Remove BOM (U+FEFF ZWNBSP at start of data) only if the `input_encoding`_
    configuration setting is None, '', 'utf-8-sig', 'utf-16', or 'utf-32'.
    Do not remove other ZWNBSPs.

* Output changes:

  HTML5:
    Stop setting the "footnote-reference" class value for footnote
    references. Use the CSS selector ``[role="doc-noteref"]``
    (works since Docutils 0.18, see minimal.css for examples).

    Fix MathML rendering problems in Chrome/Chromium based browsers.

    Embed SVG images as ``<svg>`` instead of data-URI.

  manpage:
    Use .EE/.EX macros for literal blocks.

    Render URI references (do not use .UR/.UE).

    Use box option for tables.

* Removed objects:

  `docutils.nodes.reprunicode`, `docutils.nodes.ensure_str()`
    Python 2 compatibility hacks
  `docutils.utils.Reporter.set_conditions()`
    obsolete
  `docutils.core.Publisher.setup_option_parser()`
    internal, obsolete

* New files:

  ``docutils/writers/html5_polyglot/italic-field-names.css``
    Alternative style for Docutils field-lists.

* Removed files:

  ``install.py``, ``setup.py``
    Metadata is now stored in ``pyproject.toml``,
    supported by pip_ since version 19.0 (2019-01-22).
    See README__ for installation alternatives.

  __ README.html#installation

* Bugfixes and improvements (see HISTORY_).

.. Note::

   Docutils 0.20 is the last version supporting Python 3.7 and 3.8.

* General

  - Support Python 3.11 (patch #198 by Hugo van Kemenade).

    (UTF-8 is the default encoding for LaTeX2e since 2018).

* Configuration changes:

  - Settings in the [latex2e writer] configuration file section
    are now ignored by the "xetex" writer.
    Place common settings in section `[latex writers]`_.

  - New command line setting output_. Obsoletes the ``<destination>``
    positional argument (cf. `future changes`__).

    __ `command-line usage pattern`_

* `utils.find_file_in_dirs()` now returns a POSIX path also on Windows;
  `utils.get_stylesheet_list()` no longer converts ``\`` to ``/``.

* docutils/languages/
  docutils/parsers/rst/languages/

  - Support Ukrainian. Patch by Dmytro Kazanzhy.

* Drop support for Python 2.7, 3.5, and 3.6.

* Output changes:

  HTML5:
    Wrap groups of footnotes in an ``<aside>`` for easier styling.

    The CSS rule ``.footnote-list { display: contents; }`` can be used to
    restore the behaviour of custom CSS styles.

* After package installation, the CLI commands ``python -m docutils`` and
  ``docutils`` start the `generic command line front end tool`_.

* Support parsing "Markdown" input with 3rd party parsers
  myst_, pycmark_, or recommonmark_.

* The default values for the "pep-references", "rfc-base-url",
  and "python-home" `configuration settings`_ now use the "https:" scheme.
  The PEP-writer template's header is updated to fix links and
  resemble the header of official PEPs.

* Various bugfixes and improvements (see HISTORY_).

.. _generic command line front end tool:
    docs/user/tools.html#generic-command-line-front-end
.. _myst: https://pypi.org/project/myst-docutils
.. _pycmark: https://pypi.org/project/pycmark/
.. _recommonmark: https://pypi.org/project/recommonmark/
.. _configuration settings: docs/user/config.html


Release 0.18.1 (2021-12-23)
===========================

.. Note::

   Docutils 0.18.1 is the last version supporting Python 2.7, 3.5, and 3.6.

* ``nodes.Node.traverse()`` returns a list again to restore backwards
  compatibility (fixes bug #431).
  Use ``nodes.Node.findall()`` to get an iterator.

* re-add module ``parsers.rst.directives.html``
  (stub, emits deprecation warning and loads
  "Meta" directive from its new place at ``parsers.rst.directives.misc``.)

* Small bugfixes (see HISTORY_).


Release 0.18 (2021-10-26)
=========================

* Output changes:

  Identifiers:
    - During `identifier normalization`_, leading number and hyphen
      characters are no longer stripped from a `reference name`_, if the
      id_prefix_ setting is non-empty.

      Example:
        with ``--id-prefix="DU-"``, a section with title "34. May"
        currently gets the identifier key ``DU-may`` and after the
        change the identifier key ``DU-34-may``.

    - The default value for the auto_id_prefix_ setting changed to ``%``:
      "use the tag name as prefix for auto-generated IDs".
      Set auto_id_prefix_ to ``id`` for unchanged auto-IDs.

  HTML5:
    - Use the semantic tag <aside> for footnote text and citations, topics
      (except abstract and toc), admonitions, and system messages.
      Use <nav> for the Table of Contents.

    - Make "auto" table column widths the default: Only specify column
      widths, if the `"widths" option`_ is set and not "auto".
      The table-style__ setting "colwidths-grid" restores the current default.

      __ docs/user/config.html#table-style

    - Items of a definition list with class argument "details" are
      converted to `details disclosure elements`_. Example::

        ..class:: details

        Summary
          This additional information should be hidden.

    - Do not add "compound-first", "compound-middle", or "compound-last" to
      elements nested in a compound. Use child selector and ":first-child",
      ":last-child" pseudo classes instead.

    - Use class value "backrefs" instead of "fn-backref" for a span of
      back-references.

    - Write footnote brackets and field term colons to HTML, so that they
      are present also without CSS and when copying text.

    - Move space character between section number and heading into
      "sectnum" span.

  `math-output`_: html
    - Support more commands, fix mapping of commands to Unicode characters.
    - Scale variable sized operators and big delimiters with CSS.
    - Don't use <tt> element (deprecated in HTML5).
    - Use STIX fonts if available.

  LaTeX:
     `legacy_class_functions`_ setting default changed to "False",
     admonitions are now environments.

* New standard Docutils doctree node: <meta__>.

  __ docs/ref/doctree.html#meta

* New configuration settings:

  - [latex writers] legacy_column_widths_ and
  - [html5 writer] image_loading_.

* Removed files:
  ``iepngfix.htc`` and ``blank.gif`` (IE 6 workaround for `s5_html`).

* Removed sub-module:
  ``parsers.rst.directives.html``
  (reversed in release 0.18.1).

* Removed function: utils.unique_combinations()
  (obsoleted by itertools.combinations()).

* Removed attributes:

  - ``HTMLTranslator.topic_classes``: check ``node.parent.classes`` instead.
  - ``nodes.Text.rawsource``: we store the null-escaped text in Text
    nodes since 0.16 so there is no additional information in the
    rawsource.

* Major refactoring and fixes/additions in
  ``docutils/utils/math/math2html.py`` and
  ``docutils/utils/math/latex2mathml.py``
  (mathematical notation in HTML, cf. `LaTeX syntax for mathematics`_).

* nodes.Node.traverse() returns an iterator instead of a list
  (reversed in release 0.18.1).

* Various bugfixes and improvements (see HISTORY_).

  Fix spelling errors in documentation and docstrings.

===========================

* Bug fixes (for details see the Docutils `HISTORY`_).

Release 0.17 (2021-04-03)
=========================

* Numerous bug fixes and improvements
  (for details see the Docutils `HISTORY`_).

* Installing with ``setup.py`` now requires setuptools_.
  Alternatively, install with pip_.

* The generic command line front end tool docutils-cli.py_ allows
  the free selection of reader, parser, and writer components.

* Support Arabic language.

* New, **experimental** wrapper to integrate the `recommonmark`__
  Markdown parser for use with Docutils.
  Currently only tested with recommonmark version 0.4.0.

  __ https://pypi.org/project/recommonmark/

* HTML5 writer:

  - New option embed_images_.

  - Use semantic tags (for details see the Docutils `HISTORY`_).

  - Change the `initial_header_level`_ setting's default to "2", as browsers
    use the `same style for <h1> and <h2> when nested in a section`__.

  - New optional style ``responsive.css``, adapts to different screen
    sizes.

  - Move non-essential styling from ``minimal.css`` to ``plain.css``
    rsp. ``responsive.css``.

  - Show code line numbers as pseudo-elements so they are skipped when
    copying the code block from the page.

  __ https://stackoverflow.com/questions/39547412/same-font-size-for-h1-and-h2-in-article
  .. _embed_images: docs/user/config.html#embed-images

* LaTeX writer:

  - New configuration setting `legacy_class_functions`_.

  - The special value "auto" for the `graphicx_option`_ setting
    is no longer supported (it never worked for xetex/luatex).

  - `Styling commands`__ using the legacy ``\docutilsrole`` prefix are
    now ignored. Use ``\DUrole``.

    __ docs/user/latex.html#classes

  - Most helper commands and element definitions are now defined in the
    LaTeX package `docutils.sty`_ and only inserted in the document
    preamble if the stylesheet__ setting does not lists "docutils".

    __ docs/user/config.html#stylesheet-latex-writers

  - Remove legacy LaTeX stylesheet ``docutils-05-compat.sty``.

Release 0.16 (2020-01-12)
=========================

Docutils 0.16.x supports Python 2.7 and Python >= 3.5 natively,
without the use of the ``2to3`` tool.

* reStructuredText:

  - Keep `backslash escapes`__ in the document tree. This allows, e.g.,
    escaping of author-separators in `bibliographic fields`__.

  __ https://docutils.sourceforge.io/docs/ref/rst/restructuredtext.html#escaping-mechanism
  __ docs/ref/rst/restructuredtext.html#bibliographic-fields

* LaTeX writer:

  - Informal titles of type "rubric" default to bold-italic and left aligned.
  - Deprecate ``\docutilsrole`` prefix for styling commands:
    use ``\DUrole`` instead.
  - Fix topic subtitle.
  - Add "latex writers" to the `config_section_dependencies`.
  - Ignore classes for `rubric` elements
    (class wrapper interferes with LaTeX formatting).

* tools/buildhtml.py

  - New option ``--html-writer`` allows to select "html" (default),
    "html4" or "html5" (deprecated in favour of the `"writer" setting`_
    in Docutils 0.18).

* docutils/io.py

  - Remove the `handle_io_errors` argument from io.FileInput/Output.

* docutils/nodes.py

  - If `auto_id_prefix`_ ends with "%", this is replaced with the tag name.

* Various bugfixes and improvements (see HISTORY_).

.. _"writer" setting: docs/user/config.html#writer-buildhtml-application

* reStructuredText:

  - Allow embedded colons in field list field names (before, tokens like
    ``:this:example:`` were considered ordinary text).

  - Fixed a bug with the "trim" options of the "unicode" directive.

* languages: Added Korean localisation (ko).


Release 0.14 (2017-08-03)
=========================

.. Note::

* docutils/writers/_html_base:

  - Provide default title in metadata.
  - The MathJax CDN shut down on April 30, 2017. For security reasons, we
    don't use a third party public installation as default but warn
    if `math-output` is set to MathJax without specifying a URL.
    See math-output_ for details.

* docutils/writers/html4css1:

  - Respect automatic table column sizing.

* docutils/writers/latex2e/__init__.py

    Changed behaviour of the default settings:
      if there is a file ``html4css1.css`` in the working directory of the
      process at launch, it is used instead of the one provided by Docutils
      in the writer source directory.

========================

Docutils 0.6 is compatible with Python versions from 2.3 up to 2.6
and convertible to 3.1 code.

.. note::

   The "newlatex" writer is orphaned.

* reStructuredText:

  - Allow length units for all length specifications.
  - Allow percent sign in "scale" argument of "figure" and "image" directives.

    (allows setting the alignment of an image in a figure).
  - Hard tabs **in literal inclusions** are replaced by spaces.

  - Set sub- and superscript role argument as text not math.
  - Support custom roles based on standard roles.
  - Load packages and define macros only if required in the document.

    section numbering by LaTeX.
  - Use default font in admonitions and sidebar.
  - Typeset generic topic as "quote with title".
  - Use template (file and configuration option).
