Abstract

This document covers topics specific to Docutils' LaTeX export.

# 1 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.

## 1.1 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 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.

## 1.2 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` [1].

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.

[1] | DU for Documentation Utilities = Docutils

## 1.3 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".

# 2 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.

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.

# 3 Configuration

## 3.1 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.

## 3.2 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}}%
      }

### 3.2.1 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.

## 3.3 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

### 3.3.1 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.

### 3.3.2 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

### 3.3.3 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

### 3.3.4 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.

# 4 How to configure the ...

## 4.1 admonitions

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

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.

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.

## 4.2 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 [2] or as raw LaTeX in the document source, text styled with `:custom4:`large bold small-caps`` will be typeset accordingly.

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

## 4.3 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}

## 4.4 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

## 4.5 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}

## 4.6 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.

## 4.7 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.

## 4.8 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}

## 4.9 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}

## 4.10 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.

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
  1. 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.
  2. 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 [3]:

        \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.

  [3] | 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}

### 4.10.1 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:

1. 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

2. 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).

3. 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

4. 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 [4]
   `-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

     good legibility but very wide.

   Charter

     bread-and-butter type optimized for printing on low-resolution printers

   New Century Schoolbook

     good legibility but very wide.

   Palatino

     `+1` | recommended by font experts
     `+1` | good LaTeX support including matching math fonts, small caps, old-style figures
     `-1` | bad rendering in xpdf viewer (auto-hinting leads to different x-hight for different characters at some magnifications) (this is fixed in recent versions).

   Times

     `+1` | the serif PDF Standard Font,
     `-1` | overused and quite narrow (devised for multi-column layouts).

   Utopia

     recommended by font experts

   Font packages for standard Postscript fonts (cf. Using common Postscript fonts with LaTeX)
   Package | Roman | Sans Serif | Typewriter | Math
   --- | --- | --- | --- | ---
   (none) | CM Roman | CM Sans Serif | CM Typewriter | CM Math
   mathpazo | Palatino |  |  | Palatino
   mathptmx | Times |  |  | Times
   helvet |  | Helvetica |  |
   avant |  | Avant Garde |  |
   courier |  |  | Courier |
   chancery | Zapf Chancery |  |  |
   bookman | Bookman | Avant Garde | Courier |
   newcent | New Century Schoolbook | Avant Garde | Courier |
   charter | Charter |  |  |
   utopia | Utopia |  |  |
   fourier | Utopia |  |  | Fourier

[4] | Extended versions of the standard Postscript fonts including accented chars, as well as real small-caps and old-style numbers are available with the TeX Gyre bundle which is part of, e.g., TeX Live.

## 4.11 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

## 4.12 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].

## 4.13 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%
      }

## 4.14 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

## 4.15 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.

### 4.15.1 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}

## 4.16 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}

## 4.17 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}

## 4.18 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}

## 4.19 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}}

## 4.20 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

## 4.21 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}

## 4.22 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).

## 4.23 page layout

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

The following packages help to configure the page layout:

1. 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.

2. 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}.

## 4.24 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}

## 4.25 page numbering

Example:

  Number pages by chapter (using the chappg package):

      \usepackage{chappg}

  See the chappg documentation for details.

## 4.26 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.

## 4.27 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}

## 4.28 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}}

## 4.29 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').

## 4.30 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).

## 4.31 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

## 4.32 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.

## 4.33 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}{}{}%
      }

## 4.34 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}

## 4.35 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.

## 4.36 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}}}

## 4.37 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".

## 4.38 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}}

# 6 Problems

## 6.1 Troubleshooting

### 6.1.1 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.

### 6.1.2 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!

### 6.1.3 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:

  1. compile with pdflatex,
  2. use the package breakurl,
  3. (for printout) disable hyperlinks using the package "nohyperref".

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

### 6.1.4 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".

### 6.1.5 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.

### 6.1.6 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).

### 6.1.7 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".

### 6.1.8 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.

### 6.1.9 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).

### 6.1.10 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).

## 6.2 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.

### 6.2.1 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.

### 6.2.2 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).

### 6.2.3 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.)

### 6.2.4 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).
