<title>Writing Documentation with DocBook</title>

<para>
|
|
DocBook is a flavor of <acronym>SGML</acronym>
|
|
(<firstterm>Standard Generalized Markup
|
|
Language</firstterm>), a syntax for marking up the contents
|
|
of documents. HTML is another very common flavor of SGML;
|
|
DocBook markup looks very similar to HTML markup, although
|
|
the names of the markup tags differ.
|
|
</para>
|
|
|
|
<sect3>
|
|
<title>Terminology</title>
|
|
|
|
<para>
|
|
SGML markup contains a number of syntactical elements that
|
|
serve different purposes in the markup. We'll run through
|
|
the basics here to make sure we're on the same page when
|
|
we refer to SGML semantics.
|
|
</para>
|
|
<para>
|
|
The basic currency of SGML is the
|
|
<firstterm>tag</firstterm>. A simple tag consists of a
|
|
pair of angle brackets and the name of the tag. For
|
|
example, the <sgmltag>para</sgmltag> tag would appear in
|
|
an SGML document as <sgmltag
|
|
class="starttag">para</sgmltag>. This start tag indicates
|
|
that the immediately following text should be classified
|
|
according to the tag. In regular SGML, each opening tag
|
|
must have a matching end tag to show where the start tag's
|
|
contents end. End tags begin with
|
|
<quote><literal></</literal></quote> markup, e.g.,
|
|
<sgmltag class="endtag">para</sgmltag>.
|
|
</para>
|
|
<para>
|
|
The combination of a start tag, contents, and an end tag
|
|
is called an <firstterm>element</firstterm>. SGML
|
|
elements can be nested inside of each other, or contain
|
|
only text, or may be a combination of both text and other
|
|
elements, although in most cases it is better to limit
|
|
your elements to one or the other.
|
|
</para>
|
|
<para>
|
|
The <acronym>XML</acronym> (<firstterm>eXtensible Markup
|
|
Language</firstterm>) specification, a modern subset of
|
|
the SGML specification, adds a so-called <firstterm>empty
|
|
tag</firstterm>, for elements that contain no text
|
|
content. The entire element is a single tag, ending with
|
|
<quote><literal>/></literal></quote>, e.g.,
|
|
<sgmltag><xref/></sgmltag>. However, use of this
|
|
tag style restricts you to XML DocBook processing, and
|
|
your document may no longer compile with SGML-only
|
|
processing systems.
|
|
</para>
|
|
<!-- *** Note: We could normally use the "emptytag"
|
|
attribute for XML empty tags, but that's only a recent
|
|
addition, and we don't want to screw up documents
|
|
generated against older stylesheets.
|
|
*** -->
|
|
<para>
|
|
Often a processing system will need more information about
|
|
an element than you can provide with just tags. SGML
|
|
allows you to add extra <quote>hints</quote> in the form
|
|
of SGML <firstterm>attributes</firstterm> to pass along
|
|
this information. The most common use of attributes in
|
|
DocBook is giving specific elements a name, or an ID, so
|
|
you can refer to it from elsewhere. This ID can be used
|
|
for many things, including file-naming for HTML output,
|
|
hyper-linking to specific parts of the document, and even
|
|
pulling text from that element (see the <sgmltag
|
|
class="starttag">xref</sgmltag> tag).
|
|
</para>
|
|
<para>
|
|
An SGML attribute appears inside the start tag, between
|
|
the < and > brackets. For example, if you wanted to
|
|
set the <sgmltag class="attribute">id</sgmltag> attribute
|
|
of the <sgmltag class="starttag">book</sgmltag> element to
|
|
<quote>mybook</quote>, you would create a start tag like
|
|
this: <programlisting><book id="mybook"></programlisting>
|
|
</para>
|
|
<para>
|
|
Notice that the contents of the attribute are enclosed in
|
|
quote marks. These quotes are optional in SGML, but
|
|
mandatory in XML. It's a good habit to use quotes, as it
|
|
will make it much easier to migrate your documents to an
|
|
XML processing system later on.
|
|
</para>
|
|
<para>
|
|
You can also specify more than one attribute in a single
|
|
tag: <programlisting><book id="mybook" status="draft"></programlisting>
|
|
</para>
|
|
<para>
|
|
Another commonly used type of SGML markup is the
|
|
<firstterm>entity</firstterm>. An entity lets you
|
|
associate a block of text with a name. You declare the
|
|
entity once, at the beginning of your document, and can
|
|
invoke it as many times as you like throughout the
|
|
document. You can use entities as shorthand, or to make
|
|
it easier to maintain certain phrases in a central
|
|
location, or even to insert the contents of an entire file
|
|
into your document.
|
|
</para>
|
|
<para>
|
|
An entity in your document is always surrounded by the
|
|
<quote>&</quote> and <quote>;</quote> characters. One
|
|
entity you'll need sooner or later is the one for the
|
|
<quote><</quote> character. Since SGML expects all
|
|
tags to begin with a <quote><</quote>, the
|
|
<quote><</quote> is a reserved character. To use it in
|
|
your document (as I am doing here), you must insert it
|
|
with the <literal>&lt;</literal> entity. Each time
|
|
the SGML processor encounters <literal>&lt;</literal>,
|
|
it will place a literal <quote><</quote> in the output
|
|
document. Similarly you must use the <literal>&gt;</literal>
|
|
and <literal>&amp;</literal> entities for the
|
|
<quote>></quote> and <quote>&</quote> characters.
|
|
</para>
|
|
<para>
|
|
The final term you'll need to know when writing simple
|
|
DocBook documents is the <acronym>DTD</acronym>
|
|
(<firstterm>Document Type Declaration</firstterm>). The
|
|
DTD defines the flavor of SGML a given document is written
|
|
in. It lists all the legal tag names, like <sgmltag
|
|
class="starttag">book</sgmltag>, <sgmltag
|
|
class="starttag">para</sgmltag>, and so on, and declares
|
|
how those tags are allowed to be used together. For
|
|
example, it doesn't make sense to put a <sgmltag
|
|
class="starttag">book</sgmltag> element inside a <sgmltag
|
|
class="starttag">para</sgmltag> paragraph element -- only
|
|
the reverse.
|
|
</para>
|
|
<para>
|
|
The DTD thus defines the legal structure of the document.
|
|
It also declares which attributes can be used with which
|
|
tags. The SGML processing system can use the DTD to make
|
|
sure the document is laid out properly before attempting
|
|
to process it. SGML-aware text editors like <link
|
|
linkend="emacs-psgml">Emacs</link> can also use the DTD to
|
|
guide you while you write, offering you choices about
|
|
which tags you can add in different places in the
|
|
document, and beeping at you when you try to add a tag
|
|
where it doesn't belong.
|
|
</para>
|
|
<para>
|
|
Generally, you will declare which DTD you want to use as
|
|
the first line of your SGML document. In the case of
|
|
DocBook, you will use something like this:
|
|
<programlisting><!doctype book PUBLIC "-//OASIS//DTD
|
|
DocBook V3.1//EN" []> <book> ...
|
|
</book></programlisting>
|
|
</para>
|
|
<para>
|
|
Note that you must specify your toplevel element inside
|
|
the doctype declaration. If you were writing an article
|
|
rather than a book, you might use this declaration instead:
|
|
<programlisting><!doctype article PUBLIC "-//OASIS//DTD DocBook V3.1//EN" []>
|
|
<article>
|
|
...
|
|
</article></programlisting>
|
|
</para>
|
|
</sect3>
|
|
|
|
<sect3 id="sgml-document">
|
|
<title>The Document</title>
|
|
<para>
|
|
Once you're comfortable with SGML, creating a DocBook
|
|
document is quite simple and straightforward. Even
|
|
though DocBook contains over 300 different tags, you can
|
|
usually get by with only a small subset of those tags.
|
|
Most of them are for inline formatting, rather than for
|
|
document structuring. Furthermore, the common tags have
|
|
short, intuitive names.
|
|
</para>
|
|
<para>
|
|
Below is a (completely nonsensical) example to illustrate
|
|
how a simple document might be laid out. Notice that all
|
|
<sgmltag class="starttag">chapter</sgmltag> and <sgmltag
|
|
class="starttag">sect1</sgmltag> elements have <sgmltag
|
|
class="attribute">id</sgmltag> attributes. This is not
|
|
mandatory, but is a good habit to get into, as DocBook is
|
|
commonly converted into HTML, with a separate generated
|
|
file for each <sgmltag class="starttag">book</sgmltag>,
|
|
<sgmltag class="starttag">chapter</sgmltag>, and/or <sgmltag
|
|
class="starttag">sect1</sgmltag> element. If the given
|
|
element has an <sgmltag class="attribute">id</sgmltag>
|
|
attribute, the processor will typically name the file
|
|
accordingly. Thus, the below document might result in
|
|
<filename>index.html</filename>,
|
|
<filename>chapter-one.html</filename>,
|
|
<filename>blobs.html</filename>, and so on.
|
|
</para>
|
|
<para>
|
|
Also notice the text marked off with <quote><!--
|
|
</quote> and <quote> --></quote> characters. These
|
|
denote SGML comments. SGML processors will completely
|
|
ignore anything between these markers, similar to
|
|
<quote>/*</quote> and <quote>*/</quote> comments in C
|
|
source code.
|
|
</para>
|
|
|
|
<!-- Encase the following SGML excerpt inside a CDATA
|
|
block so we don't have to bother converting all
|
|
brackets to entities

Once you get used to the syntax of SGML, the next hurdle
|
|
in writing DocBook documentation is to learn the many
|
|
DocBook-specific tag names, and when to use them. DocBook
|
|
was created for technical documentation, and as such, the
|
|
tag names and document structure are slanted towards the
|
|
needs of such documentation.
|
|
</para>
|
|
<para>
|
|
To cover its target audience, DocBook declares a wide
|
|
variety of specialized tags, including tags for formatting
|
|
source code (with somewhat of a C/C++ bias), computer
|
|
prompts, GUI application features, keystrokes, and so on.
|
|
DocBook also includes tags for universal formatting needs,
|
|
like headers, footnotes, tables, and graphics.
|
|
</para>
|
|
<para>
|
|
We won't cover all of these elements here (over 300
|
|
DocBook tags exist!), but we will cover the basics. To
|
|
learn more about the other tags, check out the official
|
|
DocBook guide, at <ulink
|
|
url="http://docbook.org">http://docbook.org</ulink>. To
|
|
see how they are used in practice, download the SGML
|
|
source for this manual (the Wine Developer Guide) and
|
|
browse through it, comparing it to the generated HTML (or
|
|
PostScript or PDF).
|
|
</para>
|
|
<para>
|
|
There are often many correct ways to mark up a given piece
|
|
of text, and you may have to make guesses about which tag
|
|
to use. Sometimes you'll have to make compromises.
|
|
However, remember that it is possible to further <link
|
|
linkend="docbook-tweaking">customize the output</link> of
|
|
the SGML processors. If you don't like the way a certain
|
|
tag looks in HTML, that doesn't mean you should choose a
|
|
different tag based on its output formatting. The
|
|
processing stylesheets can be altered to fix the
|
|
formatting of that same tag everywhere in the document
|
|
(not just in the place you're working on). For example,
|
|
if you're frustrated that the <sgmltag
|
|
class="starttag">systemitem</sgmltag> tag doesn't produce
|
|
any formatting by default, you should fix the stylesheets,
|
|
not change the valid <sgmltag
|
|
class="starttag">systemitem</sgmltag> tag to, for example,
|
|
an <sgmltag class="starttag">emphasis</sgmltag> tag.
|
|
</para>
|
|
<para>
|
|
Here are the common SGML elements:

<para>
|
|
The book is the most common toplevel element, and is

probably the one you should use for your document.

If you want to group more than one book into a
|
|
single unit, you can place them all inside a set.
|
|
This is useful when you want to bundle up
|
|
documentation in alternate ways. We do this with
|
|
the Wine documentation, using a <sgmltag
|
|
class="starttag">set</sgmltag> to put everything
|
|
into a single directory (see
|
|
<filename>documentation/wine-doc.sgml</filename>),
|
|
and a <sgmltag class="starttag">book</sgmltag> to
|
|
put each Wine guide into a separate directory (see
|
|
<filename>documentation/wine-devel.sgml</filename>,
|
|
etc.).

If the chapters in your book fall into major
|
|
categories or groupings (as in the Wine Developer
|
|
Guide), you can place each collection of chapters
|
|
into a <sgmltag class="starttag">part</sgmltag>
|

element.

<para>
|
|
DocBook has many section elements to divide the
|
|
contents of a chapter into smaller chunks. The
|
|
encouraged approach is to use the numbered section
|
|
tags, <sgmltag class="starttag">sect1</sgmltag>,
|
|
<sgmltag class="starttag">sect2</sgmltag>, <sgmltag
|
|
class="starttag">sect3</sgmltag>, <sgmltag
|
|
class="starttag">sect4</sgmltag>, and <sgmltag
|
|
class="starttag">sect5</sgmltag> (if necessary).
|
|
These tags must be nested in order: you can't place
|
|
a <sgmltag class="starttag">sect3</sgmltag> directly
|
|
inside a <sgmltag class="starttag">sect1</sgmltag>.
|
|
You have to nest the <sgmltag
|
|
class="starttag">sect3</sgmltag> inside a <sgmltag
|
|
class="starttag">sect2</sgmltag>, and so forth.
|
|
Documents with these explicit section groupings are
|
|
easier for SGML processors to deal with, and lead to
|
|
better organized documents. DocBook also supplies a
|
|
<sgmltag class="starttag">section</sgmltag> element
|
|
which you can nest inside itself, but its use is
|
|
discouraged in favor of the numbered section tags.

<sgmltag class="starttag">part</sgmltag>, and the
|
|
various section tags, <sgmltag

class="starttag">title</sgmltag> is mandatory. In
|
|
other elements like <sgmltag
|
|
class="starttag">book</sgmltag> and <sgmltag
|
|
class="starttag">note</sgmltag>, it's optional.

The basic unit of text is the paragraph, represented
|
|
by the <sgmltag class="starttag">para</sgmltag> tag.
|
|
This is probably the tag you'll use most often. In
|
|
fact, in a simple document, you can probably get
|
|
away with using only <sgmltag
|
|
class="starttag">book</sgmltag>, <sgmltag
|
|
class="starttag">chapter</sgmltag>, <sgmltag
|
|
class="starttag">title</sgmltag>, and <sgmltag

<term><sgmltag class="starttag">quote</sgmltag></term>

<para>
|
|
An inline quotation. This tag typically inserts
|
|
quotation marks for you, so you would write <sgmltag
|
|
class="starttag">quote</sgmltag>This is a
|
|
quote<sgmltag class="endtag">quote</sgmltag> rather
|
|
than "This is a quote". This usage may be a little
|
|
bulkier, but it does allow for automated formatting
|
|
of all quoted material in the document. Thus, if
|
|
you wanted all quotations to appear in italic, you
|
|
could make the change once in your stylesheet,
|
|
rather than doing a search and replace throughout
|
|
the document. For larger chunks of quoted text, you
|
|
can use <sgmltag
|
|
class="starttag">blockquote</sgmltag>.

<listitem>

<para>
|
|
Insert a side note for the reader. By default, the
|
|
SGML processor usually prefixes the content with
|
|
"Note:". You can change this text by adding a
|
|
<sgmltag class="starttag">title</sgmltag> element.
|
|
Thus, to add a visible FIXME comment to the
|
|
documentation, you might write:
|
|
</para>
|
|
<programlisting>
|
|
<![CDATA[
|
|
<note>
|

|
|
<para>This section needs more info about...</para>
|

|

|
|
<para>
|
|

|
|
</para>
|

Generic hypertext link, used for pointing to other

sections within the current document. You supply
|
|
the visible text for the link, plus the name of the <sgmltag
|
|
class="attribute">id</sgmltag> attribute of the
|
|
element that you want to link to. For example:
|
|
<programlisting><link linkend="configuring-wine">the section on configuring wine</link>
|
|
...
|
|
<sect2 id="configuring-wine">
|
|
...</programlisting>

<varlistentry>
|
|
<term><sgmltag class="starttag">xref</sgmltag></term>
|
|
<listitem>
|
|
<para>
|
|
In-document hyperlink that can generate its own
|
|
text. Similar to the <sgmltag
|
|
class="starttag">link</sgmltag> tag, you use the
|
|
<sgmltag class="attribute">linkend</sgmltag>
|
|
attribute to specify which target element you want
|
|
to jump to:
|
|
</para>
|
|
<para>
|
|
<programlisting><xref linkend="configuring-wine">
|
|
...
|
|
<sect2 id="configuring-wine">
|
|
...</programlisting>
|
|
</para>
|
|
<para>
|
|
By default, most SGML processors will autogenerate
|
|
some generic text for the <sgmltag
|
|
class="starttag">xref</sgmltag> link, like
|
|
<quote>Section 2.3.1</quote>. You can use the
|
|
<sgmltag class="attribute">endterm</sgmltag>
|
|
attribute to grab the visible text content of the
|
|
hyperlink from another element:
|
|
</para>
|
|
<para>
|
|
<programlisting><xref linkend="configuring-wine" endterm="config-title">
|
|
...
|
|
<sect2 id="configuring-wine">
|
|
<title id="config-title">Configuring Wine</title>
|
|
...</programlisting>
|
|
</para>
|
|
<para>
|
|
This would create a link to the
|
|
<symbol>configuring-wine</symbol> element,
|
|
displaying the text of the
|
|
<symbol>config-title</symbol> element for the
|
|
hyperlink. Most often, you'll add an <sgmltag
|
|
class="attribute">id</sgmltag> attribute to the
|
|
<sgmltag class="starttag">title</sgmltag> of the
|
|
section you're linking to, as above, in which case
|
|
the SGML processor will use the target's title text
|
|
for the link text.
|
|
</para>
|
|
<para>
|
|
Alternatively, you can use an <sgmltag
|
|
class="attribute">xreflabel</sgmltag> attribute in
|
|
the target element tag to specify the link text:
|
|
</para>
|
|
<programlisting><sect1 id="configuring-wine" xreflabel="Configuring Wine"></programlisting>
|
|
<note>
|
|
<para>
|
|
<sgmltag class="starttag">xref</sgmltag> is an
|
|
empty element. You don't need a closing tag for
|
|
it (this is defined in the DTD). In SGML
|
|
documents, you should use the form <sgmltag
|
|
class="starttag">xref</sgmltag>, while in XML
|
|
documents you should use
|
|
<sgmltag><xref/></sgmltag>.

The following packages seems to be sufficient for RedHat 7.1. You
|
|
will want to be careful about the order in which you install the
|

rpms.

<para>

Although you can write SGML documentation in any simple text
|
|
editor, some editors provide extra support for entering SGML
|
|
tags, and for verifying that the SGML you create is valid.
|
|
SGML has been around for a long time, and many commercial
|
|
editors exist for it; however, until recently open source
|
|
SGML editors have been scarce.

The most commonly used open source SGML editor is Emacs,
|
|
with the PSGML <firstterm>mode</firstterm>, or extension.
|
|
Emacs does not supply a GUI or WYSIWYG (What You See Is What
|
|
You Get) interface, but it does provide many helpful
|
|
shortcuts for creating SGML, as well as automatic
|
|
formatting, validity checking, and the ability to create
|
|
your own macros to simplify complex, repetitive actions.
|
|
We'll touch briefly on each of these points.

The first thing you need is a working installation of Emacs
|
|
(or XEmacs), with the PSGML package. Most Linux
|
|
distributions provide both as easy-to-install packages.

Next, you'll need a working SGML environment. See <xref

up.
