LaTeX
=====

LaTeX__, is a document preparation system for high-quality typesetting. It
is most often used for medium-to-large technical or scientific documents but
it can be used for almost any form of publishing. There exists a wide
selecton of `LaTeX Documentation on the net`_ and `books on LaTeX and
related topics`_. For an introduction to LaTeX see, e.g., `LaTeX2e for
authors`_.

__ http://www.latex-project.org/
.. _LaTeX2e for authors:
   http://www.latex-project.org/guides/usrguide.pdf
.. _LaTeX Documentation on the net:
   http://www.latex-project.org/guides/
.. _books on LaTeX and related topics:
   http://www.latex-project.org/guides/books.html

.. _LaTeX packages:

LaTeX classes and packages
--------------------------

Unlike HTML with CSS, LaTeX uses one common language for markup and style
definitions. Separation of content and style is realized by collecting style
definitions in LaTeX classes and packages, or the
`document preamble <LaTeX preamble_>`_.

LaTeX document classes and packages (similar to Python modules or C
libraries) provide means to extend or modify the LaTeX language by
redefining macros or providing new ones.

Using the `document class`_ and `style sheet`_ configuration options, you
can select from a *huge* selection of classes and packages (standard as well
as user contributed) coming with your TeX distribution or available at
CTAN_ as well as custom style sheets.

.. _CTAN: http://www.ctan.org

Docutils specific LaTeX macros
------------------------------

Some Docutils objects have no LaTeX counterpart, they will be typeset
using a Docutils specific LaTeX *macro* (command, environment, or
length) to allow customization. By convention, special macros use the
prefix ``\DU``\ [#]_.

The generated LaTeX documents should be kept processable by a standard LaTeX
installation. Therefore fallback definitions are included after the `custom
style sheets`_, if a macro is required in the document.

* Custom `style sheets`_ can define alternative implementations with
  ``\newcommand``, ``\newenvironment``, and ``\newlength`` followed by
  ``\setlength``.

* Definitions with `raw LaTeX`_ are part of the document body. Use
  ``\def``, ``\renewcommand`` or ``\renewenvironment``, and ``\setlength``.

See the test output standalone_rst_latex.tex_ for an example of the fallback
definitions and their use in the document.

.. [#] DU for Documentation Utilities = Docutils

Length units
------------

LaTeX supports all `length units`_ defined for Docutils plus the
following less common units:

:pt: typewriter's (or LaTeX) point (1 pt = 1/72.27 in)
:dd: didôt (1 dd = 1238/1157 pt)
:cc: cîcero (1 cc = 12 dd)
:sp: scaled point (1sp = 1/65536pt)

.. attention:: Different definitions of the unit "pt"!

* In Docutils (as well as CSS) the unit symbol "pt" denotes the
     `Postscript point` or `DTP point`.

* LaTeX uses "pt" for the `LaTeX point`, which is unknown to Docutils and
     0.3 % smaller.

* The `DTP point` is available in LaTeX as "bp" (big point):

1 pt = 1/72.25 in < 1 bp  = 1/72 in

Lengths specified in the document with unit "pt" will be given the
   unit "bp" in the LaTeX source.

In `raw LaTeX`_ and `custom style sheets`_, the `DTP point` must be
   specified as "bp", while "pt" is interpreted as `LaTeX point`.

The default length unit (added by Docutils to length specifications
without unit) is the "DTP point".

.. _length units: ../ref/rst/restructuredtext.html#length-units

PDF generation
==============

In most cases, LaTeX code is not the desired end-format of the document.
LaTeX offers many ways to generate PDF documents from the LaTeX
source, including:

_`pdflatex`
  Generates a PDF document directly from the LaTeX file.

_`xelatex` or _`lualatex`
  The `XeTeX`_ and LuaTeX_ engines work with input files in UTF-8 encoding
  and system fonts. Export your document with the `xetex` writer
  (``rst2xetex``), if you want to go this route.

You may need to call latex two or three times to get internal references
correct.

.. _documentoptions: config.html#documentoptions
.. _xetex: http://tug.org/xetex/
.. _luatex: http://luatex.org/

_`rubber`
  The Rubber__ wrapper for LaTeX and friends can be used to automatically
  run all programs the required number of times and delete "spurious" files.
  This includes processing bibliographic references or indices, as well as
  compilation or conversion of figures.

Configuration

Options/Settings
----------------

Options can be specified as

* command-line options, or

* configuration settings.

Run ``rst2latex.py --help`` to get a list of available options;
see `Docutils Configuration`_ for details.

.. _Docutils Configuration:
   config.html

Classes
-------

The `"classes" attribute`_ is one of the common attributes, shared by all
Docutils elements.
In HTML, the common use is to provide selection criteria for style rules in
CSS stylesheets. As there is no comparable framework for LaTeX, Docutils
mimics some of this behaviour via `Docutils specific LaTeX macros`_.

*Inline elements*
  are handled via the ``\DUrole{}`` macro, that calls the optional styling
  command ``\DUrole«classargument»`` with one argument (the role content).
  See `custom interpreted text roles`_.

*Block level elements*
  are wrapped in "class environments":
  ``\begin{DUclass}`` calls the optional styling command
  ``\DUCLASSe«classargument»{}``, ``\end{DUclass}`` tries
  ``\endDUCLASS«classargument»``.

Customization is done by defining matching macros or environments.

Example 1:
  Use small caps font inside elements with class value "custom".

*Inline elements*
    The LaTeX function ``\textsc`` sets the argument in small caps::

\newcommand{\DUrolesmallcaps}[1]{\textsc{#1}}

*Block-level elements*
    The LaTeX directive (macro without argument) ``\scshape`` switches to
    the small caps font. Its effect is confined to the wrapper ``DUclass``
    environment::

\newcommand*{\DUCLASScustom}{\scshape}

Example 2:
  It is even possible to locally redefine other LaTeX macros, e.g. to
  turn bullet lists with class value "enumerateitems" into enumerated
  lists::

\newcommand*{\DUCLASSenumerateitems}{%
      \renewenvironment{itemize}{\begin{enumerate}}%
                                {\end{enumerate}}%
    }

Notes
`````

* Class arguments may contain numbers and hyphens, which need special
  treatment in LaTeX command names (see `class directive`_). The commands
  ``\csname`` and ``\endcsname`` or the special command ``\@namedef`` can
  help with the definition of corresponding macros or environments, e.g.::

\expandafter\newcommand\csname gg1\endcsname{Definition of gg1.}

or ::

\makeatletter
    \@namedef{DUadmonitionadmonition-test}{…}
    \makeatother

* Elements can have multiple class arguments. In contrast to HTML/CSS, the
  order of the class arguments cannot be ignored in LaTeX

* For "historical reasons", class handling differs for some elements and
  class values:

* The special macros ``\DUadmonition``, ``\DUtitle``, and ``\DUtopic`` are
    written with a comma separated list of class values as optional
    argument.  See http://www.ctan.org/topic/keyval for LaTeX packages that
    help parsing value lists.

See the sections on admonitions_, titles_, and the `topic element`_ for
    customization examples.

* Class argument values starting with ``align-`` are transformed to
    "align" argument values. Class argument values starting with
    ``language-`` set the elements language property.

* The table element recognizes some special class values. See section
    table_.

.. _"classes" attribute: ../ref/doctree.html#classes

LaTeX code
----------

Custom LaTeX code can be placed in `style sheets`_, the
`LaTeX preamble`_, the document body (`raw LaTeX`_), or custom templates_.

The functional tests that come with Docutils, can serve as example.

input:
  standalone_rst_latex.txt_ (includes files from `tests/functional/input/data`_)
expected output:
  standalone_rst_latex.tex_

.. _standalone_rst_latex.txt:
  https://sf.net/p/docutils/code/HEAD/tree/trunk/docutils/test/functional/input/standalone_rst_latex.txt
.. _tests/functional/input/data:

.. _standalone_rst_latex.tex:
   https://sf.net/p/docutils/code/HEAD/tree/trunk/docutils/test/functional/expected/standalone_rst_latex.tex?format=raw

.. _style sheet:
.. _custom style sheets:

Style sheets
````````````

A common way of LaTeX customization is the preparation of custom style
sheets, either as simple files with LaTeX code snippets or as home-made
`LaTeX packages`_ (see the clsguide_ for an introduction on LaTeX
package writing).

Options:
  stylesheet_

It is possible to specify multiple style sheets and mix `LaTeX
  packages`_ with custom style sheets.

You cannot specify package options with the stylesheet_ setting. If
you need to pass options to the package, use the ``\usepackage``
command in the `LaTeX preamble`_ or a custom style sheet.

Example 1:
  Select Latin Modern fonts with the `lmodern` package::

--stylesheet=lmodern

Example 2:
  Use the `preamble.tex` home-made custom style sheet together with
  the package `kerkis` (Bookman fonts)::

--stylesheet=kerkis,preamble.tex

Example 3:
  Select Palatino fonts with old-style numbers and true small-caps
  with the LaTeX command ::

\usepackage[osf,sc]{mathpazo}

in the `LaTeX preamble`_ or `custom style sheets`_.

Stylesheet Repository
  There is a `repository of user-contributed style sheets`_ in the
  Docutils Sandbox_.

.. _clsguide:
   http://mirror.ctan.org/macros/latex/doc/clsguide.pdf
.. _stylesheet:
   config.html#stylesheet-latex2e-writer
.. _embed-stylesheet:
   config.html#embed-stylesheet-latex2e-writer
.. _repository of user-contributed style sheets:
   ../../../sandbox/stylesheets/
.. _sandbox: ../../../sandbox/

LaTeX preamble
``````````````

Configuration by LaTeX code in the document preamble is also possible
without a separate stylesheet. This way, packages can be loaded with
options or commands re-defined without the need to create a separate
file (new in Docutils 0.7).

Option:
  latex-preamble_

Default:
  used for `font setup`_

Example:
  To use the better looking ``txtt`` font for monospaced text define the
  latex-preamble_ setting in a configuration file::

latex-preamble: \renewcommand{\ttdefault}{txtt}
                     \usepackage{mathptmx}          % Times
                     \usepackage[scaled=.92]{helvet}  % Helvetica

.. _latex-preamble:
   config.html#latex-preamble
.. _PDF standard fonts:
   http://en.wikipedia.org/wiki/PDF#Standard_Type_1_Fonts
.. _Linux Libertine:
   http://www.linuxlibertine.org/index.php?id=1&L=1

Templates
`````````

Some customizations require commands at places other than the insertion
point of stylesheets or depend on the deletion/replacement of parts of the
document. This can be done via a custom template. See the `publisher
documentation`_ for a description of the document parts available in a
template file.

Option:
  template_

In addition to the 'default.tex' template, the latex writer directory
contains the alternative 'titlepage.tex'.

Example:
  Print a title page including docinfo, dedication, and abstract::

--template=titlepage.tex

.. _publisher documentation: ../api/publisher.html
.. _template: config.html#template-latex2e-writer

Raw LaTeX
`````````

By means of the `raw directive`_ or a derived `custom role`_, one can
give commands directly to LaTeX. These can be both, styling as well as
printing commands.

Example:
  Math formula::

.. raw:: latex

\[x^3 + 3x^2a + 3xa^2 + a^3,\]

(Drawback: the formula will be invisible in other output formats. Better
  use the `math directive`_)

Most LaTeX code examples also work as raw LaTeX inside the document.
An exception are commands that need to be given in the document
preamble (e.g. package loading with ``\usepackage``, which can be
achieved with the ``--style-sheet`` or ``--latex-preamble`` command
line options instead). Remember to use *re-defining* commands for
customizing `Docutils specific LaTeX macros`_ with raw LaTeX.

Example:
  Define the transition command as page break::

.. raw:: latex

\renewcommand*{\DUtransition}{\pagebreak[4]}

See also:
  * Defining a macro for a `custom role`_.
  * Forcing `page breaks`_.

   ../ref/rst/directives.html#raw
.. _math directive:
   ../ref/rst/directives.html#math

How to configure the ...
========================

admonitions
-----------

Admonitions__ are specially marked "topics" that can appear anywhere an
ordinary body element can.

__ ../ref/rst/directives.html#admonitions

Command:
  ``\DUadmonition``

Default:
  Typeset in a frame (90 % of text width).

The admonition title is typeset with the ``\DUtitle`` command which also
takes a class argument. See `titles`_

Example 1:
  A lighter layout without the frame::

\newcommand{\DUadmonition}[2][class-arg]{%
      % try \DUadmonition#1{#2}:
      \ifcsname DUadmonition#1\endcsname%
        \csname DUadmonition#1\endcsname{#2}%
      \else
        \begin{quote}
          #2
        \end{quote}
      \fi
    }

The first part of this definition acts as a "dispatcher". This way it is
  possible to define a special handling of `specific admonitions`_ based on
  the "class" argument.

.. _specific admonitions:
   ../ref/rst/directives.html#specific-admonitions

Example 2:
  Use ``.. note::`` for a margin note::

\newcommand{\DUadmonitionnote}[1]{\marginpar{#1}}

Make sure there is enough space to fit the note.
  See also the marginnote_ and pdfcomment_ packages.

.. _marginnote:
   http://mirror.ctan.org/help/Catalogue/entries/marginnote.html
.. _pdfcomment:
   http://mirror.ctan.org/help/Catalogue/entries/pdfcomment.html

.. _custom role:

custom interpreted text roles
-----------------------------

The rst `role directive`_ allows defining custom `text roles`_ that mark
parts of inline text (spans) with class arguments (see section classes_).

Commands:
  ``\DUrole``: dispatcher command

``\DUrole«classargument»``: optional styling command with 1 argument (the
  role content).

Default:
  The default definition of ``\DUrole{«classargument»}{}`` calls the macro
  named ``\DUrole«classargument»{}`` if it is defined and silently ignores
  this class argument if not.

Example 1:
  Typeset text in small caps::

.. role:: smallcaps

:smallcaps:`Fourier` transformation

This is transformed to the LaTeX code::

\DUrole{smallcaps}{Fourier} transformation

The definition ::

\newcommand{\DUrolesmallcaps}{\textsc}

as `raw LaTeX`_ or in the custom `style sheet`_ will give the expected
  result (if the text font_ supports small caps).

Example 2:
  Subscript text in normal size and *italic* shape::

.. role:: sub(subscript)

As "sub" inherits from the standard "subscript" role, the LaTeX macro
  only needs to set the size and shape::

\newcommand{\DUrolesub}{\normalsize\itshape}

Example 3:
  A role with several classes and a converted class name::

.. role:: custom4
       :class: argI argII arg_3

is translated to the nested commands::

\DUrole{argi}{\DUrole{argii}{\DUrole{arg-3}{<content>}}}

With the definitions::

\newcommand{\DUroleargi}[1]{\textsc}
    \newcommand{\DUroleargii}[1]{{\large #1}}
    \makeatletter
    \@namedef{DUrolearg-3}{\textbf}
    \makeatother

in a `style sheet`_\ [#]_ or as `raw LaTeX`_ in the document source,
  text styled with ``:custom4:`large bold small-caps``` will be typeset
  accordingly.

.. [#] Leave out the ``\makeatletter`` - ``\makeatother`` pair if the style
   sheet is a LaTeX package (``*.sty``).

.. _role directive:
   ../ref/rst/directives.html#role

.. _text roles:
   ../ref/rst/roles.html

.. _class directive:
   ../ref/rst/directives.html#class

definition lists
----------------

ReStructuredText `definition lists`__ correspond to HTML ``<dl>`` list
objects.

Environment:
  ``description``: LaTeX standard environment

Command:
  ``\descriptionlabel``: styling macro for the description term

Default:
  bold label text, hanging indent

Example:
  A non-bold label can be achieved with::

\renewcommand\descriptionlabel[1]{\hspace\labelsep \normalfont #1}

__ ../ref/rst/restructuredtext.html#definition-lists

document class
--------------

There are hundreds of LaTeX document classes installed by modern
LaTeX distributions, provided by publishers, or available at CTAN_.

Popular document classes:
  * article, report, book: standard document classes
  * scrartcl, scrrprt, scrbook: KOMA-script_ classes
  * memoir_: highly configurable class for larger documents

Option:
  documentclass_

.. _KOMA-script:
   http://mirror.ctan.org/help/Catalogue/entries/koma-script.html
.. _memoir:
   http://mirror.ctan.org/help/Catalogue/entries/memoir.html
.. _documentclass:
   config.html#documentclass

document info
-------------

Content of the `bibliographic fields`__ at the top of a document.
By default, docinfo items are typeset as a table.

Options:
  use-latex-docinfo_, use-latex-abstract_

Length:
  ``\DUdocinfowidth``: the width for the `docinfo` table.

Default:
  90 % of text width: ``0.9\textwidth``

Example:
  set to 70 % of text width::

\newlength{\DUdocinfowidth}
    \setlength{\DUdocinfowidth}{0.7\textwidth}

__ ../ref/rst/restructuredtext.html#bibliographic-fields

.. _use-latex-docinfo:
   config.html#use-latex-docinfo
.. _use-latex-abstract:
   config.html#use-latex-abstract

document title
--------------

A lone top-level section title is (usually) transformed to the document title
(see `section structure`_).

The format of the document title is defined by the `document class`_. The
"article" document class uses an in-page title and the "report" and "book"
classes write a separate title page. See the `TeX FAQ`_ on how to customize
the `style of document titles`_.

The default title page shows only title and subtitle, date and author
are shown in the `document info`_ table.

Options:
  use-latex-docinfo_

``--template=titlepage.tex`` Put docinfo and abstract into the title page.
  A separate title page is used also with the "abstract" document class.

.. _section structure: rst/quickref.html#section-structure
.. _TeX FAQ: http://www.tex.ac.uk/faq
.. _style of document titles:
   http://www.tex.ac.uk/cgi-bin/texfaq2html?label=titlsty

field lists
-----------

`Field lists`__ may be used as generic two-column table constructs in
documents.

Environment:
   ``DUfieldlist``

Default:
   Indented description list.

Example:
   Use a description list customized with enumitem_::

\usepackage{enumitem}
     \newenvironment{DUfieldlist}%
       {\description[font=,style=sameline,leftmargin=8em]}
       {\enddescription}
     }

The `KOMA-script`_ classes provide a similar environment under the name
   `labeling`.

.. _enumitem:
   http://mirror.ctan.org/help/Catalogue/entries/enumitem.html

__ ../ref/rst/restructuredtext.html#field-lists

figure and table captions
-------------------------

The caption_ package provides many ways to customise the captions in
floating environments like figure and table.

The chngcntr_ package helps to configure the numbering of figure and table
caption numberings.

Some document classes (e.g. KOMA-script_) provide additional configuration.
Also see the related `LaTeX FAQ entry`__

Example
  ::

\usepackage{caption}
    \captionsetup{justification=raggedleft,singlelinecheck=false}

.. _caption:
   http://mirror.ctan.org/help/Catalogue/entries/caption.html
.. _chngcntr:
   http://mirror.ctan.org/help/Catalogue/entries/chngcntr.html
__ http://www.tex.ac.uk/cgi-bin/texfaq2html?label=running-nos

figure placement
----------------

Figures_ might be typeset at the place of definition (default) or "float"
to a suitable place at the top or bottom of a page. This is implemented
using the float_ package.

Command:
  ``\floatplacement``

The placement setting is valid from the point of definition until the next
``\floatplacement`` command or the end of the document. See float.pdf_ for
details.

Default:
  ``\floatplacement{figure}{H}`` (here definitely). This corresponds most
  closely to the source and HTML placement (principle of least surprise).

Example 1:
  In a custom `style sheet`_, set the default to let LaTeX find a suitable
  place for figure floats::

\usepackage{float}
    \floatplacement{figure}{htbp} % here, top, bottom, extra-page

Example 2:
  To move all following figures to the top or bottom of the page write in
  the document source::

.. raw:: latex

\floatplacement{figure}{tb}

.. _figures: ../ref/rst/directives.html#figure
.. _float:
   http://mirror.ctan.org/help/Catalogue/entries/float.html
.. _float.pdf:
   http://mirror.ctan.org/macros/latex/contrib/float/float.pdf

.. _font setup:

font
----

The selected text font influences the *look*, the *feel*,
and the *readability* of the document (cf.
http://www.csarven.ca/web-typography).
Selecting a suitable font also solves the problem with `bad looking
PDF output`_.

Font selection is one of the main differences between LaTeX and XeTeX/LuaTeX:

LaTeX
  cannot use the fonts of the operating system directly but needs
  specially installed fonts with additional supporting files.

XeTeX/LuaTeX
  can use system fonts and provides access to the full feature set of
  modern OpenType_ fonts.

.. _OpenType: http://en.wikipedia.org/wiki/OpenType

The default font setup is done in the latex-preamble_:

LaTeX
  `PDF standard fonts`_ (Times, Helvetica, Courier)

XeTeX/LuaTeX
  `Linux Libertine`_, a free, high quality alternative to Times with a
  wide coverage of glyphs, styles, and OpenType features.

Despite its name, Linux Libertine can be used on any operating
  system that can handle OpenType fonts.

Alternative fonts can be selected by

LaTeX
  a) specifying the corresponding LaTeX package(s) as argument to the
     stylesheet_ option_ or with the ``\usepackage`` LaTeX command.

* packages can be combined,
     * passing options to a package is only possible in a `style sheet`_
       or the `LaTeX preamble`_.

b) changing the font-default macros ``\rmdefault``, ``\sfdefault``
     and/or ``\ttdefault`` in a custom `style sheet`_, the `LaTeX
     preamble`_ or `raw LaTeX`_.

Example 1:
    Use `Latin Modern`_. `LaTeX code`_::

\usepackage{lmodern}

Command line argument::

--stylesheet=lmodern

Example 2:
    The _`Times/Helvetica/Courier` `PDF standard fonts`_ are
    selected by the LaTeX code [#]_::

\usepackage{mathptmx}            % Times for serif and math
      \usepackage[scaled=.90]{helvet}  % downscaled Helvetica for sans serif
      \usepackage{courier}             % Courier for teletype (mono-space)

Since Docutils 0.7, this is the default value of the
    `latex-preamble`_ option.

.. [#] When generating PDF-files from LaTeX, the `PDF standard
     fonts`_ do not need to be embedded in the document. While this
     results in smaller files, the actually used fonts on screen and in
     print might differ! (For details see, e.g., the testflow_ package
     documentation.)

Example 3:
    Use the teletype font from the txfonts_ package. As there is no
    package for this, we re-define the font macro with the `LaTeX code`_::

\renewcommand{\ttdefault}{txtt}

XeTeX/LuaTeX
  using the macros of the fontspec_ package. Use some font-viewer or
  -manager (e.g. fontmatrix_) to find out the correct names of the
  fonts on your system.

Example:
    DejaVu_, very wide coverage, screen optimized. As this font
    runs wide, add ``DIV=10`` to the `documentoptions`_::

\setmainfont{DejaVu Serif}
      \setsansfont{DejaVu Sans}
      \setmonofont[HyphenChar=None]{DejaVu Sans Mono}

.. _fontspec: http://mirror.ctan.org/help/Catalogue/entries/fontspec.html
.. _fontmatrix: http://fontmatrix.net/
.. _DejaVu: http://dejavu-fonts.org/
.. _documentoptions: config.html#documentoptions

choice of suitable fonts
````````````````````````

High quality free fonts suitable for use with XeTeX/LuaTeX are, e.g., listed
at `Good Libre Fonts`_, `25 Best Free Quality Fonts`_ and the update
`19 More Free Quality Fonts`_.

The `LaTeX Font Catalogue`_ provides information and examples for a wide
range of fonts available for use with LaTeX. Here is just a selection:

a) The `Latin Modern`_ (LM) fonts are extended outline versions of the
   standard TeX font Computer Modern (CM).

+1  simple invocation:  ``--stylesheet=lmodern``

+1  keeps the traditional TeX "look and feel":

+1  generally accepted as high quality CM replacement,
       +1  comprehensive math support,
       +1  including optical sizes,
       +1  compatible with extensions made to match CM,
       -1  modern types are hard to read at low (screen) resolutions.

-1  not part of a minimal standard TeX installation

b) CM-Super_ is another outline CM replacement.

+1  simple invocation: modern LaTeX distributions use CM-Super
       automatically instead of CM if it is installed.

-1  said to be of inferior quality compared to LM.

-1  not part of a minimal standard TeX installation,
       bigger download size than Latin Modern (64 MB).

c) `Bera`_ (Bitstream Vera)

+1  simple invocation:  ``--stylesheet=bera``

+1  optimized for on-screen viewing with goot hinting

-1  not part of a minimal standard TeX installation

d) PSNFSS_ Postscript fonts

+1  part of every standard TeX installation

+1  smaller PDF/Postscript document size if standard fonts are not
       embedded

-1  restricted set of glyphs in the free versions [#]_

-1  different fonts for roman, sans-serif and typewriter fonts.

-1  invocation somewhat more complex, as several packages are
       required for a complete font set, sometimes including package
       options.

Roman (serif) PSNFSS fonts:

Bookman

font encoding
-------------

LaTeX font encodings are described in detail in the encguide_ which is
part of the LaTeX base documentation.

Option:
  font-encoding_

Default:
  "T1"

Example 1:
  Use the (obsolete) LaTeX default encoding "OT1"::

--font-encoding=OT1

or (without loading the fontenc_ package)::

--font-encoding=""

This will improve the look on screen with the default Computer Modern
  fonts at the expense of problems with `search and text extraction`_
  The recommended way is to select a T1-encoded "Type 1" (vector)
  font, for example `Latin Modern`_

Example 2:
  Support for characters in the Unicode blocks Latin, Latin-1 Supplement,
  and Greek together with a T1-encoded "Type 1" (vector) font, for example
  `Latin Modern`_::

--font-encoding=LGR,T1 --stylesheet=lmodern

.. _encguide:
   http://mirror.ctan.org/macros/latex/doc/encguide.pdf
.. _font-encoding:
   config.html#font-encoding
.. _fontenc:
   http://mirror.ctan.org/help/Catalogue/entries/fontenc.html

font size
---------

Add font size in points to the document options, e.g.
``--documentoptions=12``, use e.g. the document classes provided by
extsizes_ for values other than [10,11,12].

.. _extsizes:
   http://mirror.ctan.org/help/Catalogue/entries/extsizes.html

footnotes
---------

By default, footnotes are set with Docutils-specific wrappers around
the standard ``\footnotemark`` and ``\footnotetext`` commands.  You
can configure the footnote layout similar to standard LaTeX footnotes
in a custom `style sheet`_ or the `LaTeX preamble`_.

Further configuration is possible by alternative definitions of
``\DUfootnotemark`` and ``\DUfootnotetext``

Example 1:
  Set footnote text with a hanging indent.

* This is the default with KOMA-script_ classes, e.g::

--documentclass=scrartcl

(for further configuration, see the `KOMA-script Guide`_),

* with package footmisc_::

\usepackage[hang]{footmisc}
      \setlength{\footnotemargin}{0em}

(play with the ``\footnotemargin`` setting),

* redefine ``\DUfootnotetext`` inserting `\hangindent`::

\newcommand{\DUfootnotetext}[4]{%
        \begingroup%
        \renewcommand{\thefootnote}{%
          \protect\raisebox{1em}{\protect\hypertarget{#1}{}}%
          \protect\hyperlink{#2}{#3}}%
          \footnotetext{\hangindent=2em #4}%
        \endgroup%
      }

(adapt the ``\hangindent`` value).

Example 2:
  Footnote marks in normal font size, not superscript::

\usepackage{scrextend} % not required with KOMA-script document classes
    \deffootnote{1em}{1em}{\thefootnotemark\ }

(See the `KOMA-script Guide`_ for details and other options.)

Example 3:
  Place the footnote text where it appears in the source document (instead
  of at the page bottom). This can be used to get the effect of endnotes
  (needs the hanging_ package)::

\usepackage{hanging}
     \newcommand{\DUfootnotetext}[4]{%
       \par\noindent\raisebox{1em}{\hypertarget{#1}{}}%
       \hyperlink{#2}{#3}%
       \hangpara{\parindent}{1}#4%
     }

.. _footmisc:
   http://mirror.ctan.org/help/Catalogue/entries/footmisc.html
.. _hanging:
   http://mirror.ctan.org/help/Catalogue/entries/hanging.html

hyphenation
-----------

The amount of hyphenation is influenced by ``\hyphenpenalty``, setting it to
10000 almost prevents hyphenation. As this produces lines with more space
between words one should increase Latex's ``\tolerance`` for this.

Example:
  ::

\hyphenpenalty=5000
    \tolerance=1000

hyperlinks
----------

Options:
  hyperlink-color_, hyperref-options_

Hyperlinks are realized using the hyperref_ package. As it re-defines many
standard LaTeX macros, this package is loaded last, *after* the style
sheets.

However, you can load hyperref before a package that requires its
presence in a `style sheet`_ or the `LaTeX preamble`_ (see example
below). This will ignore options set with hyperlink-color_ and
hyperref-options_.

URLs are typeset with the "url" package (loaded implicitely by "hyperref").
The font of URLs can be defined with the ``\urlstyle`` command. Valid
arguments are

:same:  normal text font, Docutils default,
:tt:    teletype (monospaced), LaTeX default,
:rm:    roman,
:sf:    sans serif

Example:
  Custom loading of the hyperref package also switches to
  the LaTeX default (monospaced fonts for URLs). Reset to use the text
  font::

\usepackage[unicode,colorlinks=true,linkcolor=green]{hyperref}
   \urlstyle{same}

See also `non-breaking hyperlinks`_.

.. _hyperlink-color:
   config.html#hyperlink-color
.. _hyperref-options:
   config.html#hyperref-options

disable hyperlinks
``````````````````

To suppress the hyper-linking completely (e.g. for printing or to
avoid clashes with other packages), set hyperref-options_ to "draft"
or load the "nohyperref" package that comes with the "hyperref"
bundle.

Option:
  ``--hyperref-options=draft``

`LaTeX code`_::

\usepackage{nohyperref,url}
  \urlstyle{same}

.. _hyperref:
   http://mirror.ctan.org/help/Catalogue/entries/hyperref.html

line blocks
-----------

In `line blocks`__, newlines and leading whitespace are respected.

Environment:
  ``DUlineblock``: special list environment for line blocks

Length:
  ``\DUlineblockindent``: indentation of indented lineblock parts.

Default:
   2.5 times the font hight: ``2.5em``

Example:
  set to the paragraph indentation::

\newlength{\DUlineblockindent}
    \setlength{\DUlineblockindent}{\parindent}

__ ../ref/rst/restructuredtext.html#line-blocks

line spacing
------------

Commands:
  ``\linespread``: for small adjustments

``\singlespacing``, ``\onehalfspacing``, and ``\doublespacing``: from
  package `setspace`

Example 1:
  Get document wide double spacing::

\usepackage{setspace}
    \doublespacing

Example 2:
  Increase line spacing by five percent for better readability::

\linespread{1.05}

literal blocks
--------------

No markup processing is done within a `literal block`__. It is left as-is,
and is typically rendered in a monospaced typeface

Option:
  literal-block-env_

Example:

``--literal-block-env=lstlisting``

The ``lstlisting`` environment is highly configurable (as documented in
  listings.pdf_), for instance ::

\renewcommand{\ttdefault}{txtt}
    \lstset{language=Python, morekeywords=[1]{yield}}
    \lstloadlanguages{Python}
    \lstset{
      basicstyle=\ttfamily,
      keywordstyle=\bfseries,
      commentstyle=\rmfamily\itshape,
      stringstyle=\slshape,
    }
    \lstset{showstringspaces=false}
    \lstset{columns=fullflexible,
         basewidth={0.5em,0.4em}}

The indentation of literal blocks can be reset with ::

\lstset{resetmargins=true}

and/or configured with e. g.::

\lstset{xleftmargin=-2em}

__ ../ref/rst/restructuredtext.html#literal-blocks
.. _literal-block-env:
   config.html#literal-block-env
.. _listings.pdf:
    http://mirror.ctan.org/macros/latex/contrib/listings/listings.pdf

lists
-----

Remove extra vertical whitespace between items of bullet lists and
enumerated lists.

Example:
  Pass the class argument "compact" to the list::

.. class:: compact

* first item
    * second item

The following lines for the `LaTeX preamble`_ use the enumitem_ package to
  remove spacing from all lists with class argument "compact"::

\usepackage{enumitem}
    \newcommand*{\DUCLASScompact}{\setlist{noitemsep}}

list of figures/tables
----------------------

Docutils does not support lists of figures or tables.

However, with LaTeX, they can be generated using `raw LaTeX`_ in the
document source.

Commands:
  ``\listoffigures``: a list of figures

``\listoftables``: a list of tables

Example:
  ::

.. raw:: latex

\listoffigures

option list
-----------

`Option lists`__ are two-column lists of command-line options and
descriptions, documenting a program's options.

Environment:
  ``DUoptionlist``: environment for option lists,

Command:
  ``\DUoptionlistlabel``: set appearance of the options

Example:
  set command options with a bold monospace font::

\newcommand{\DUoptionlistlabel}{\texttt{\textbf{#1}} \hfill}

__ ../ref/rst/restructuredtext.html#option-lists

page breaks
-----------

* Page breaks before top-level sections are the default with a
  documentclass that provides "chapters", e.g.  "book", "memoir" or
  "scrbook".

* Redefining the \section or \section* command in a
  style sheet is possible too.

* `Raw LaTeX`_ or a `custom role`_ can be used.

* The transition element can be re-defined to produce a page break,

Commands
  ``\newpage``:  hard pagebreak at exactly this position

``\pagebreak[2]``: recommended page break after line end (precedence 1...4)

Example:
  Define the transition command as page break with the `LaTeX code`_::

\newcommand*{\DUtransition}{\pagebreak[4]}

(use ``\renewcommand`` with `raw LaTeX`_).

page layout
-----------

By default, paper size and margin settings are determined by the document
class.

The following packages help to configure the page layout:

a) The `typearea`_ package (part of the `KOMA-script`_ bundle) calculates a
   *good* page layout (based on rules and recommendations of typography
   experts).

See the `KOMA-Script Guide`_ for details on what is a *good* layout and
   how this is achieved.

b) The `geometry`_ package is recommended if you have to follow guidelines
   with fixed values for the margins.
   For details see the `geometry manual`_.

Example 1:
  Let `typearea` determine the type area with ``DIV=calc`` in the
  documentoptions::

--documentoptions='a4paper,DIV=calc'

The ``DIV`` option can also be specified, like ``DIV=10``. It defines how
  "crowded" a page will be: larger values mean larger text area (at the
  expense of readability).

Example 2:
  `LaTeX code`_ to set margins with the geometry_ package::

\usepackage{geometry}
    \geometry{hmargin={3cm,0.8in},height=8in}
    \geometry{height=10in}.

.. _typearea:
   http://mirror.ctan.org/help/Catalogue/entries/typearea.html
.. _KOMA-Script Guide:
   http://mirror.ctan.org/macros/latex/contrib/koma-script/scrguien.pdf
.. _geometry:
   http://mirror.ctan.org/help/Catalogue/entries/geometry.html
.. _geometry manual:
   http://mirror.ctan.org/macros/latex/contrib/geometry/geometry.pdf

page headers and footers
------------------------

With the fancyhdr_ package or the `KOMA-script`_ classes, you can define
custom page head- and foot-lines.

The `"header" and "footer" directives`_ save their content in the macros
``\DUheader`` rsp. ``\DUfooter``. The macros can be used in LaTeX code and
will be replaced by LaTeX with the content of the directives.

Example:
  `LaTeX code`_ to place left-aligned "header" and "footer" on every
  page with fancyhdr_::

\usepackage{fancyhdr}
    \fancyhead[L]{\DUheader}
    \fancyfoot{} % reset
    \fancyfoot[L]{\DUfooter}
    \pagestyle{fancy}

.. _fancyhdr: http://www.ctan.org/pkg/fancyhdr
.. _"header" and "footer" directives: ../ref/rst/directives.html#header

page numbering
--------------

Example:
  Number pages by chapter (using the chappg_ package)::

\usepackage{chappg}

See the `chappg documentation`_ for details.

.. _chappg:
   http://mirror.ctan.org/help/Catalogue/entries/chappg.html
.. _chappg documentation:
   http://mirror.ctan.org/macros/latex/contrib/chappg/chappg.pdf

paper size
----------

Paper geometry can be changed using ``--documentoptions`` or with the
`geometry`_ package.

`LaTeX code`_::

\usepackage{geometry}
  \geometry{OPTIONLIST}

Default:
  a4paper

Some possibilities:

* a4paper, b3paper, letterpaper, executivepaper, legalpaper
* landscape, portrait, twoside.

Example:
  Choose A5 pager in landscape orientation with command line argument::

--documentoptions=a5paper,landscape

The same with LaTeX commands in the `style sheet`_::

\usepackage{geometry}
    \geometry{a5paper,landscape}

For details see the `geometry manual`_.

paragraph indent
----------------

Default (in most document classes):
  Indent the first line in a paragraph unless it is the first line of a
  chapter, section, subsection, or subsubsection.

Example 1:
  To set paragraph indentation to zero but add a vertical space between
  load the `parskip` package with the command line argument::

--stylesheet=parskip

or in a custom `style sheet`_ with::

\usepackage{parskip}

Example 2:
  To suppress the indentation of a specific paragraph, you may give it the
  class "noindent" with, e.g. ::

.. class:: noindent

This paragraph should not be indented.

and define the `custom role`_ command::

\newcommand{\DUrolenoindent}[1]{\noindent #1}

rubric
------

A rubric__ is like an informal heading that doesn't correspond to the
document's structure.

Command:
  ``\DUrubric``

Default:
  subsubsection style, italic, centred

Example:
  set flushleft and red::

\newcommand*{\DUrubric}[1]{%
       \subsubsection*{{\color{red}#1}\hfill}}

__ ../ref/rst/directives.html#rubric

section numbering
-----------------

Sections are numbered if there is a `sectnum directive`_ in the document.

Option: sectnum_xform_
  ``--section-numbering``, ``--no-section-numbering``

If sectnum_xform_ is False, section numbers are generated by LaTeX. In this
case the "prefix" and "suffix" arguments of the `sectnum directive`_ are
ignored. The section number style is determined by the `document class`_
and can be configured in a LaTeX `style sheet`_, e.g.::

\setcounter{secnumdepth}{5}

.. note:: The LaTeX name is 'secnumdepth' (whithout 't').

.. _sectnum directive: ../ref/rst/directives.html#sectnum
.. _sectnum_xform: config.html#sectnum-xform

sidebar
-------

Sidebars__ are like miniature, parallel documents that occur inside other
documents, providing related or reference material. They can be likened to
super-footnotes; their content is outside of the flow of the document's main
text.

Command:
  ``DUsidebar``

Default:
  Box with grey background.

Example:
  Use margin notes::

\newcommand{\DUsidebar}[1]{\marginpar{\flushleft #1}}

* Make sure the margin is wide enough to hold the note.
  * This fails with some constructs inside the `side bar` and where
    \marginpar cannot be used, e.g., inside floats, footnotes, or in frames
    made with the framed package (see marginnote_).

__ http://docutils.sf.net/docutils/docs/ref/rst/directives.html#sidebar

size of a pixel
---------------

The length unit ``px`` is a "relative length" whose value depends on the
*resolution* of the output device (usually specified in *dots per inch*
(DPI). However, when producing a PDF, the resolution of the output device
(printer, screen (for PDF-viewer)) is generally not known.

With pdftex, the "resolution" is a configuration setting.

Default:
  72 DPI, i.e. 1 px = 1/72 in.

Example:
  Set a resolution of 96 DPI with the `LaTeX code`_::

\pdfpxdimen=1in % 1 DPI
    \divide\pdfpxdimen by 96 % 96 DPI

table
-----

A pre-configured table style can be globally selected via the table-style_
setting or set for individual tables via a `class directive`_ or the class
option of the `table directive`_.

.. _table-style: config.html#table-style-latex2e-writer
.. _table directive: ../ref/rst/directives.html#table

topic element
-------------

A topic_ is like a block quote with a title, or a self-contained section
with no subsections. Topics and rubrics can be used at places where a
`section title`_ is not allowed (e.g. inside a directive).

Example:
  Use a standard paragraph for a topic::

\newcommand{\DUCLASStopic}{%
      \renewenvironment{quote}{}{}%
    }

.. _topic: ../ref/rst/directives.html#topic
.. _section title: ../ref/rst/restructuredtext.html#sections

titles
------

The titles of admonitions_, sidebar_, and `topic element`_ are defined with
the ``\DUtitle`` command that also takes a "class" argument.

Example 1:
  a centered and somewhat larger title for topcis::

\newcommand*{\DUtitletopic}[1]{\subsection*{\centering #1}

Example 2:
  a right-pointing hand as title for the "attention" directive::

\usepackage{pifont}
    \newcommand{\DUtitleattention}[1]{\ding{43}}

The title argument is "swallowed" by the command.
  To have both, hand and title use::

\usepackage{pifont}
    \newcommand{\DUtitleattention}[1]{\ding{43} #1}

table of contents
-----------------

A `contents directive`_ is replaced by a table of contents (ToC).

Option: use-latex-toc_
  ``--use-latex-toc``, ``--use-docutils-toc``

With use-latex-toc (default since release 0.6):

* The ToC is generated by LaTeX (via the ``\tableofcontents`` command).

The layout depends on the choosen document class and can be configured in
  a custom `style sheet`_ (see e.g. the `KOMA-Script Guide`_ for the
  `KOMA-script`_ classes).

* The depth of the ToC and PDF-bookmarks can be configured

+ with the "depth" argument of the `contents directive`_, or

+ in a style sheet with e.g. ``\setcounter{tocdepth}{5}``.

* Local ToCs are done with the minitoc_ package. See the `minitoc
  documentation`_ for the numerous configuration options.

.. note::
   Minitoc supports local ToCs only at "part" and top section level
   ("chapter" or "section"). Local `contents` directives at lower levels
   are ignored (a warning is issued).

This is an intended feature of the minitoc_ package. If you really
   require local ToCs at lower level, turn off the use-latex-toc_ option.

.. _use-latex-toc: config.html#use-latex-toc
.. _contents directive: ../ref/rst/directives.html#contents
.. _minitoc:
   http://mirror.ctan.org/help/Catalogue/entries/minitoc.html
.. _minitoc documentation:
   http://mirror.ctan.org/macros/latex/contrib/minitoc/minitoc.pdf

title reference role
--------------------

`Title reference`_ is the default `default role`_ for `interpreted text`_.

Command:
  ``\DUroletitlereference``

Default:
  use slanted font (``\textsl``)

Example:
  set title references with a bold monospace font::

\newcommand{\DUroletitlereference}[1]{\texttt{\textbf{#1}}}

.. _title reference:
   ../ref/rst/roles.html#title-reference
.. _default role:
   ../ref/rst/directives.html#setting-the-default-interpreted-text-role
.. _interpreted text:
   ../ref/rst/restructuredtext.html#interpreted-text

text encoding
-------------

The encoding of the LaTeX source file is Docutils' *output* encoding
but LaTeX' *input* encoding.

Option: output-encoding_
    ``--output-encoding=OUTPUT-ENCODING``

Default:
  "utf8"

Example:
  Encode the LaTeX source file with the ISO `latin-1` (west european)
  8-bit encoding (the default in Docutils versions up to 0.6.)::

--output-encoding=latin-1

Note:
  LaTeX comes with two options for UTF-8 support,

:utf8:  by the standard `inputenc`_ package with only limited coverage
          (mainly accented characters).

:utf8x: supported by the `ucs`_ package covers a wider range of Unicode
          characters than does "utf8".  It is, however, a non-standard
          extension and no longer developed.

Currently (in version 0.6), "utf8" is used if the output-encoding is
  any of "utf_8", "U8", "UTF", or "utf8".

.. with utf8x:
   If LaTeX issues a Warning about unloaded/unknown characters adding ::

\PreloadUnicodePage{n}

(where *n* is the Unicode page-number) to the style sheet might help.

.. _ucs:
   http://mirror.ctan.org/help/Catalogue/entries/unicode.html

transition element
------------------

Transitions__ are commonly seen in novels and short fiction, as a gap
spanning one or more lines, marking text divisions or signaling changes in
subject, time, point of view, or emphasis.

Command:
  ``\DUtransition``

Default:
  A horizontal line, 1/3 of text width

Example 1:
  Use three stars::

\newcommand*{\DUtransition}{\centering{}*\quad*\quad*}

Alternatively use the more elaborated version in `transition-stars.sty`_.

Example 2:
  If paragraphs are separated by indentation, you can simply use a vertical
  space::

\newcommand*{\DUtransition}{\vspace{2ex}}

Problems
========

Troubleshooting
---------------

Bad looking PDF output
``````````````````````

What I am looking for when I try Docutils is if the PDF files I can get
  are of high quality. Unfortunaltely that never is the case.

So am I just stupid or is there a way to get really high quality pdf from
  Docutils?

Make sure the default font is not a bitmap font.

There is `Latin Modern`_ if you like the look of the standard font on paper,
but want nice pdf. Or select something else like Times, Palatino, ... via
configuration `options/settings`_. See font_ and font-encoding_.

footnote mark and text at different pages
`````````````````````````````````````````

Docutils stores the footnote text in a separate node, at the position where
it is specified in the input document. With the default settings, the
footnote is put at the bottom of the page where the footnote text is located,
maybe far away from the footnote mark (see e.g. `<rst/demo.txt>`_).

To get footnote mark and text at the same page, keep footnote mark and
footnote text close together!

non-breaking hyperlinks
```````````````````````

If you convert with ``latex`` (as opposed to ``pdflatex``), hyperlinks will
not wrap and sometimes stick into the margin.

Wrong:
  ::

\usepackage[breaklinks=true]{hyperref}

"breaklinks" is an internal option that indicates whether the chosen
  driver can handle split links. (It might work to *disable* link breaking.)

Right:
  Use one of the following:

a) compile with pdflatex_,

b) use the package breakurl_,

c) (for printout) `disable hyperlinks`_ using the package "nohyperref".

See also the `Link text doesn’t break at end line`_ LaTeX FAQ entry.

Glyph not defined in PD1 encoding
`````````````````````````````````

If a section title or other link contains non-Latin (e.g. Cyrillic)
characters, the LaTeX log contains lots of warnings like::

Package hyperref Warning: Glyph not defined in PD1 encoding,
  (hyperref)                removing `\CYRZ' on input line 6.
  ...

This can be solved with the "unicode" hyperref_option_ setting::

--hyperref-option=unicode

(works also with non-unicode input/output encoding (e.g. "koi8r" or
"latin1"). Newer versions of hyperref default to "unicode=true" if the
document language is "russian".

.. _hyperref_option: config.html#stylesheet-latex2e-writer

image inclusion
```````````````

Images__ are included in LaTeX with the help of the `graphicx` package. The
supported file formats depend on the used driver:

* pdflatex_ and xelatex_ work with PNG, JPG, or PDF, but **not EPS**.
* Standard latex_ can include **only EPS** graphics, no other format.
* latex + dvipdfmx works with EPS and JPG (add 'dvipdfmx' to the
  documentoptions_ and 'bmpsize' to the stylesheet_ setting).

If PDF-image inclusion in PDF files fails, specifying
``--graphicx-option=pdftex`` or ``--graphicx-option=auto`` might help.

For details see grfguide.pdf_.

The Rubber_ wrapper can be used for automatic image conversion.

Docutils expects an URI as pointer to the image file. The latex writer
transforms this URI to a local path. By default, LaTeX does not accept
spaces and more than one dot in the filename. If using "traditional"
filenames is not an option, adding grffile_ to the `style sheets`_
can help.

Why are my images too big?
``````````````````````````

HTML-browsers use the actual screen resolution (usually around
100 DPI).

The CSS specification suggests:

It is recommended that the reference pixel be the visual angle of one
  pixel on a device with a pixel density of 96 DPI and a distance from the
  reader of an arm's length.

-- http://www.w3.org/TR/CSS2/syndata.html#length-units

This is why pixmap images without size specification or objects with a size
specified in ``px`` tend to come too large in the PDF.

Solution:
  Specify the image size in fixed units (``pt``, ``cm``, ``in``) or
  configure the `size of a pixel`_ (length unit px).

Error ``illegal unit px``
`````````````````````````

If you convert the LaTeX source with a legacy program, you might get this
error.

The unit "px" was introduced by the `pdfTeX` converter on 2005-02-04.
`pdfTeX` is used also for conversion into DVI format in all modern LaTeX
distributions (since ca. 2006).

If updating LaTeX is not an option, just remove the "px" from the length
specification. HTML/CSS will default to "px" while the `latexe2` writer
will add the fallback unit "bp".

Error ``Symbol \textcurrency not provided`` ...
```````````````````````````````````````````````

The currency sign (\\u00a4) is not supported by all fonts (some have
an Euro sign at its place). You might see an error like::

! Package textcomp Error: Symbol \textcurrency not provided by
    (textcomp)                font family ptm in TS1 encoding.
    (textcomp)                Default family used instead.

(which in case of font family "ptm" is a false positive). Add either

:warn: turn the error in a warning, use the default symbol (bitmap), or
:force,almostfull: use the symbol provided by the font at the users
                     risk,

to the document options or use a different font package.

Search and text extraction
``````````````````````````

Search for text that contains characters outside the ASCII range (e.g.
umlauts) might fail.  See font_ and `font encoding`_ (as well as
`Searching PDF files`_ for background information).

.. _Searching PDF files:

Unicode box drawing and block characters
````````````````````````````````````````

The easiest solution is to use xelatex_ for `PDF generation`_.

With "traditional" TeX engines (e.g. pdflatex_):

- Generate LaTeX code with `output-encoding`_ "utf-8".

- Add the pmboxdraw_ package to the `style sheets`_.
  (For shaded boxes also add the `color` package.)

Unfortunately, this defines only a subset of the characters
(see pmboxdraw.pdf_ for a list).

Bugs and open issues
--------------------

Open to be fixed or open to discussion.

See also the entries in the `Docutils TODO list`_,
the BUGS_ documentation and the `SourceForge Bug Tracker`_.

Footnotes and citations
```````````````````````

Initially both were implemented using figure floats, because hyperlinking
back and forth seemed to be impossible. Later the `figure` directive was
added that puts images into figure floats.

This results in footnotes, citations, and figures possibly being mixed at
page foot.

Workaround:
  Select footnote and citation handling with the docutils-footnotes_ and
  use-latex-citations_ options.

If ``use-latex-citations`` is used, a bibliography is inserted right at
the end of the document. *This should be customizable*.

If ``use-latex-citations`` is used adjacent citation references (separated
only by a single space or a newline) are combined to a single citation
group, i.e. ``[cite1]_ [cite2]_`` results in ``\cite{cite1,cite2}``.
The appearance in the output can be configured in a `style sheet`_.

.. _use-latex-citations: config.html#use-latex-citations

Tables
``````

* reST-documents line length is assumed to be 80 characters. The
  *tablewidth* is set relative to this value. If someone produces documents
  with line length of 132 this will lead to suboptimal results.

You may use the `:width:` option to manually set the table column widths.

* Table: multicol cells are always left aligned.

* Table cells with both multirow and multicolumn are currently not possible.

* literal-blocks in table cells:

- If verbatim or flushleft is used one gets vertical space above and below.
  - This is bad for the topmost paragraph in a cell, therefore the writer
    uses raggedright.
  - Ragged right fails on followup paragraphs as the vertical space would be
    missing.

* ``--table-style=booktabs``, ``..class:: booktab``: `booktabs` version
  1.00 does not work with `longtable`. This is solved in newer versions
  (current is 2005/04/14 v1.61803).

Figures
```````

* Figures are always as wide as the containing text. The "figwidth" argument
  is currently not supported. As a consequence, the "align" argument has no
  effect.

* Wrapping text around figures is currently not supported. (Requires the
  `wrapfig`_ package.)

.. _wrapfig:
   http://mirror.ctan.org/help/Catalogue/entries/wrapfig.html

Miscellaneous
`````````````

* Pdfbookmark level 4 (and greater) does not work (might be settable but
  complicated).

* Hyperlinks are not hyphenated; this leads to bad spacing. See
  docs/user/rst/demo.txt 2.14 directives.

* Pagestyle headings does not work, when sections are starred. Use LaTeX for
  the section numbering with the `options/settings`_
  ``--no-section-numbers`` (command line) or ``sectnum_xform: False``
  (config file).
