|
||
To understand DocBook, a basic understanding of SGML is
|
||
helpful. SGML stands for Standard General Markup Language and
|
||
is one of the first markup languages every created. HTML is
|
||
actually derived from SGML and XML is a subset of SGML. SGML
|
||
uses what is called a Document Type Definition to specify
|
||
<i>elements</i> which are contained between
|
||
brackets, < and >. Text is marked by both beginning and
|
||
ending elements, for example in the DocBook DTD, one denotes a
|
||
title with <tt><title></tt>The
|
||
Title<tt></title></tt>.
|
||
</p><p>
|
||
The DTD (in the case of the GDP, DocBook) defines rules for how the
|
||
elements can be used. For example, if one element can only be used when
|
||
embedded within another, this is defined in the DTD.
|
||
</p><p>
|
||
An SGML file is just a plain ASCII file containing the text
|
||
with the markup specified above. To convert it to some easily
|
||
readable format, you need special tools. The GDP uses <i>DocBook
|
||
Tools</i>, a free package of utilities for working with DocBook
|
||
which includes <i>Jade</i>, which does the SGML/DSSL
|
||
parsing. You can read more about DocBook Tools in <a href="indexs02.html#installingdocbook" title="Installing DocBook">the section called “Installing DocBook”</a>.
|
||
</p><p>
|
||
The final appearance of the output (e.g. PostScript or HTML)
|
||
is determined by a
|
||
<i>stylesheet</i>. Stylesheets are files,
|
||
written in a special language (DSSSL -- Document Style
|
||
Semantics and Specification Language), which specify the
|
||
appearance of various DocBook elements, for example,
|
||
what fonts to use for titles and various inline elements, page
|
||
numbering style, and much more. DocBook tools come with a
|
||
collection of stylesheets (Norman Walsh's modular
|
||
stylesheets); GNOME Document Project uses some customized
|
||
version of this stylesheets -- see <a href="indexs02.html#gdpstylesheets" title="GDP Stylesheets">the section called “GDP Stylesheets”</a>.
|
||
</p><p>
|
||
The advantage of specifying the <i>structure</i>
|
||
of a document with SGML instead of specifying the
|
||
<i>appearance</i> of the document with a typical
|
||
word processor, or with html, is that the resulting document
|
||
can be processed in a variety of ways using the structural
|
||
information. Whereas formatting a document for appearance
|
||
assumes a medium (typically written text on a standard-sized
|
||
piece of paper), SGML can be processed to produce output for a
|
||
large variety of media such as text, postscript, HTML,
|
||
Braille, audio, and potentially many other formats.
|
||
</p><p>
|
||
Using 'content' as the elements to define the text of a document also
|
||
allows for search engines to make use of the actual elements to make a
|
||
"smarter search". For example, if you are searching for all documents
|
||
written by the author "Susie" your search engine could be made smart
|
||
enough to only search <author> elements, making for a faster and more
|
||
accurate search.
|
||
</p><p>
|
||
Since the overall appearance of the output is determined not by the DTD
|
||
or the SGML document, but rather by a stylesheet, the appearance of a
|
||
document can be easily changed just by changing the stylesheet. This
|
||
allows everyone in the project to create documents that all look the
|
||
same.
|
||
</p><p>
|
||
As stated before, the GDP uses the DocBook DTD. For a list of
|
||
introductory and reference resources on DocBook, see <a href="indexs15.html" title="Resources">the section called “Resources”</a>. The following sections also provide
|
||
convenient instructions on which markup tags to use in various
|
||
circumstances. Be sure to read <a href="indexs05.html" title="GDP Documentation Conventions ">the section called “GDP Documentation Conventions ”</a>
|
||
for GDP documentation-specific guidelines.

|
||
DocBook itself and GNOME Documentation project will migrate from
|
||
SGML to XML. This transition should be relatively painless:
|
||
(almost) all DocBook tags will remain the same. However, XML has
|
||
stricter syntax rules than SGML; thus, some constructions which
|
||
are valid in SGML will not be valid in XML. Therefore, to be
|
||
ready for this transistion, it is <i>strongly
|
||
advised</i> that the documentation writers conform to XML
|
||
syntax rules. Here are most important differences:
|
||
</p><div class="variablelist"><dl><dt><a name="id2936091"></a><span class="term"> <i>Minimization</i></span></dt><dd><p><a name="id2936110"></a>
|
||
It is possible with some implementations of SGML to use
|
||
minimizations to close elements in a document by using
|
||
</>, for example:
|
||
<tt><tt><title></tt>The
|
||
Title<tt></></tt></tt>. This is not
|
||
allowed in XML. You can use <b>sgmlnorm</b> command,
|
||
included in DocBook Tools package, to expand minimized tags;
|
||
if you are using Emacs with psgml
|
||
mode, you can also use menu command
|
||
Modify->Normalize.
|
||
</p></dd><dt><a name="id2936225"></a><span class="term"> <i>Self-closing tags</i></span></dt><dd><p><a name="id2936244"></a>
|
||
Also, in SGML some tags are allowed not to have closing
|
||
tags. For example, it is legal for
|
||
<tt><xref></tt> not to have a closing tag:
|
||
<tt><tt><xref
|
||
linkend="someid"></tt></tt>. In
|
||
XML, it is illegal; instead, you should use
|
||
<tt><tt><xref
|
||
linkend="someid"/></tt></tt> (note the
|
||
slash!).
|
||
</p></dd><dt><a name="id2936311"></a><span class="term"> <i>Case sensitive tags</i></span></dt><dd><p><a name="id2936327"></a>
|
||
In XML, unlike SGML, tags are case-senstive
|
||
<tt><title></tt> and
|
||
<tt><TITLE></tt> are different tags!
|
||
Therefore, please always use lowercase tags (except for
|
||
things like <tt>DOCTYPE, CDATA</tt> and
|
||
<tt>ENTITY</tt>, which are not DocBook tags).

|
||
Top-level element of a book body must be
|
||
<tt><chapter></tt>; it may contain one or more
|
||
<tt><sect1></tt>, each of them may contain
|
||
<tt><sect2></tt> and so on up to
|
||
<tt><sect5></tt>. The top-level element of an
|
||
article body is always
|
||
<tt><sect1></tt>. Regardless of which elements
|
||
you use, give each structural element a unique id, so that
|
||
you can link to it. For usage example, see the template.
|
||
</p><p> Please try to avoid using deeply nested sections; for
|
||
most situations, <tt><sect1></tt> and
|
||
<tt><sect2></tt> should be sufficient. If not,
|
||
you probably should split your <tt><sect1></tt>
|
||
into several smaller ones.
|
||
</p><p> Use the tag <tt><para></tt> for
|
||
paragraphs, even if there is only one paragraph in a
|
||
section--see template for examples.
|
||
</p></div><div class="sect3"><a name="notes"></a><div class="titlepage"><div><h4 class="title"><a name="notes"></a>Notes, Warnings, And Tips</h4></div></div><p>
|
||
For notes, tips, warnings, and important information, which
|
||
should be set apart from the main text (usually as a
|
||
paragraph with some warning sign on the margin), use tags
|
||
<tt><note></tt>, <tt><tip></tt>,
|
||
<tt><warning></tt>,
|
||
<tt><important></tt> respectively. For example:
|
||
<pre class="programlisting">
|
||
|
||
<tip>
|
||
<title>TIP</title>
|
||
<para>
|
||
To speed up program compilation, use <application>gcc</application>
|
||
compiler with Pentium optimization.
|
||
</para>
|
||
</tip> </pre> produces
|
||
</p><div class="tip" style="margin-left: 0.5in; margin-right: 0.5in;"><h3 class="title"><a name="extip"></a>TIP</h3><p>
|
||
To speed up program compilation, use
|
||
gcc compiler with Pentium
|
||
optimization. </p></div><p>
|
||
Note that this should not be inside a
|
||
<tt><para></tt> but between paragraphs.
|
||
</p></div><div class="sect3"><a name="figures"></a><div class="titlepage"><div><h4 class="title"><a name="figures"></a> Screenshots and other figures</h4></div></div><p>
|
||
To include screenshots and other figures, use the following
|
||
tags:
|
||
|
||
<pre class="programlisting">
|
||
|
||
<figure id="shot1">
|
||
<title>Screenshot</title>
|
||
<screenshot>
|
||
<screeninfo>Screenshot of a program</screeninfo>
|
||
<graphic format="PNG" fileref="figures/example_screenshot" srccredit="ME">
|
||
</graphic>
|
||
</screenshot>
|
||
</figure>
|
||
</pre>
|
||
replacing <tt>example_screenshot</tt> with the
|
||
actual file name (without extension). The result will look like this:
|
||
|
||
<div class="figure"><p><a name="shot1"></a><b>Figure 1. Screenshot</b></p><div class="screenshot"><p><img src="figures/example_screenshot"></p></div></div>
|
||
</p><div class="note" style="margin-left: 0.5in; margin-right: 0.5in;"><h3 class="title"><a name="id2936851"></a>NOTE</h3><p>
|
||
Notice in this example that the screenshot file name does
|
||
not include the file type extension -- to find out
|
||
why, please read <a href="indexs02.html#jadeimages" title="Images in DocBook Tools">the section called “Images in DocBook Tools”</a>.
|
||
</p></div></div><div class="sect3"><a name="listing"></a><div class="titlepage"><div><h4 class="title"><a name="listing"></a>Program listings and terminal session</h4></div></div><p>
|
||
To show a file fragment--for example, program
|
||
listing--use <tt><programlisting></tt> tag:
|
||
<pre class="programlisting">
|
||
|
||
<programlisting>
|
||
[Desktop Entry]
|

Icon=gnome-gnumeric.png
|
||
Terminal=0
|

|
||
Icon=gnome-gnumeric.png
|

Terminal=0
|

Type=Application
|

</pre>
|
||
As a matter of fact, all examples in this document were
|
||
produced using <tt><programlisting></tt>.
|
||
</p><p>
|
||
To show a record of terminal session--i.e., sequence of
|
||
commands entered at the command line--use
|
||
<tt><screen></tt> tag:
|
||
<pre class="programlisting">
|
||
|
||
<screen>
|
||
<prompt>bash$</prompt><userinput>make love</userinput>
|
||
make: *** No rule to make target `love'. Stop.
|
||
</screen>
|
||
</pre>
|

which produces
|

<pre class="screen">
|
||
<tt>bash$</tt><b><tt>make love</tt></b>
|
||
make: *** No rule to make target `love'. Stop.
|
||
</pre>
|
||
Note the use of tags <tt><prompt></tt> and
|
||
<tt><userinput></tt> for marking system prompt
|
||
and commands entered by user.
|
||
<div class="note" style="margin-left: 0.5in; margin-right: 0.5in;"><h3 class="title"><a name="id2937067"></a>NOTE</h3><p>
|
||
Note that both <tt><programlisting></tt>
|
||
and <tt><screen></tt> preserve linebreaks,
|
||
but interpret SGML tags (unlike LaTeX
|
||
verbatim environment). Take a look at
|
||
the source of this document to see how you can have SGML
|
||
tags literally shown but not interpreted,
|

</p></div>
|

</p></div><div class="sect3"><a name="lists"></a><div class="titlepage"><div><h4 class="title"><a name="lists"></a> Lists</h4></div></div><p>
|
||
The most common list types in DocBook are
|
||
<tt><itemizedlist></tt>,
|
||
<tt><orderedlist></tt>, and
|
||
<tt><variablelist></tt>.
|
||
</p><div class="variablelist"><dl><dt><a name="id2937185"></a><span class="term"> <tt><itemizedlist></tt></span></dt><dd><p><a name="id2937205"></a>
|
||
This is the simplest unnumbered list, parallel to
|
||
<tt><ul></tt> in HTML. Here is an example:
|
||
<pre class="programlisting">
|
||
|
||
<itemizedlist>
|
||
<listitem>
|
||
<para>
|

show any backup file that might be on your system.

</para>
|

</listitem>
|
||
<listitem>
|
||
<para>
|
||
<guilabel>Show hidden files</guilabel> &mdash; This will
|

show all "dot files" or files that begin with a dot. This
|

always having directories shown above files.
|

</para>
|

</listitem>
|

</itemizedlist>
|
||
|

</pre>
|
||
and output:
|

</p><div class="itemizedlist"><ul><li><p><a name="id2937244"></a>

</p></li></ul></div><p> Note the use of <tt>&mdash;</tt>
|
||
for long dash (see <a href="indexs04.html#specsymb" title=" Special symbols ">the section called “ Special symbols ”</a>). Also,
|
||
please note that the result looks much nicer because the
|
||
terms being explained (Show backup
|
||
files, etc.) are set in a different font. In
|
||
this case, it was achieved by using <a href="indexs04.html#gui" title="GUI elements"><tt><guilabel></tt></a>
|
||
tag. In other cases, use appropriate tags such as
|
||
<a href="indexs04.html#gui" title="GUI elements"><tt><guimenuitem></tt></a>,
|
||
<a href="indexs04.html#filenames" title="Filenames, commands, and other
|
||
computer-related things"><tt><command></tt></a>,
|

or -- if none of

this applies -- use

<a href="indexs04.html#gui" title="GUI elements"><tt><emphasis></tt></a>.

|
||
This list is completely analogous to
|
||
<tt><itemizedlist></tt> and has the same
|
||
syntax, but it produces numbered list. By default,
|
||
this list uses Arabic numerals for numbering entries;
|
||
you can override this using <tt>numeration</tt>,
|
||
for example <tt><orderedlist
|
||
numeration="lowerroman"></tt>. Possible values of
|
||
these attribute are <tt>arabic</tt>,
|
||
<tt>upperalpha</tt>,
|
||
<tt>loweralpha</tt>,
|
||
<tt>upperroman</tt>,
|
||
<tt>lowerroman</tt>.
|
||
</p></dd><dt><a name="id2937607"></a><span class="term"> <tt><variablelist></tt></span></dt><dd><p><a name="id2937625"></a> This list is used when each entry is
|
||
rather long, so it should be formatted as a block of text
|
||
with some subtitle, like a small subsection. The
|
||
<tt><variablelist></tt> is more complicated
|
||
than itemizedlists, but for larger blocks of text, or when
|
||
you're explaining or defining something, it's best to use
|
||
them. Their greatest advantage is that it's easier for a
|
||
computer to search. The lines you are reading now were
|
||
produced by <tt><variablelist></tt>. The
|
||
source looked liked this:
|
||
<pre class="programlisting">
|
||
|
||
<variablelist>
|
||
<varlistentry>
|
||
<term> <sgmltag>&lt;itemizedlist></sgmltag></term>
|
||
<listitem><para>
|
||
This is the simplest unnumbered list, parallel to
|
||
<sgmltag>&lt;ul></sgmltag> in HTML. Here is an example:...
|
||
</para></listitem>
|
||
</varlistentry>
|

<varlistentry>
|

|

Lists can be nested; in this case, the stylesheets
|
||
are smart enough to change the numeration (for
|

<tt><orderedlist></tt>) or marks of each entry

(in <tt><itemizedlist></tt>) for sub-lists

|
||
If you need to refer to a sequence of menu choices, such as
|
||
Main Menu->Utilities->GNOME
|
||
terminal
|
||
there is a special construction for this, too:
|
||
<pre class="programlisting">
|
||
|
||
<menuchoice>
|
||
<guimenu>Main Menu</guimenu> <guisubmenu>Utilities</guisubmenu>
|
||
<guimenuitem>GNOME terminal</guimenuitem> </menuchoice>

</p></div><div class="sect3"><a name="links"></a><div class="titlepage"><div><h4 class="title"><a name="links"></a>Links and references</h4></div></div><p>
|
||
To refer to another place in the same document, you can use
|
||
tags <tt><xref></tt> and
|
||
<tt><link></tt>. The first of them
|
||
automatically inserts the full name of the element you refer
|
||
to (section, figure, etc.), while the second just creates a
|
||
link (in HTML output). Here is an example:
|
||
<pre class="programlisting">
|
||
An example of a <link linkend="extip">tip</link> was given in
|
||
<xref linkend="notes" />.
|
||
</pre>

computer-related things</h4></div></div><p>
|
||
Here are some tags used to describe operating system-related
|
||
things:
|
||
</p><div class="itemizedlist"><ul><li><p><a name="id2938334"></a> <tt><filename></tt> -- used
|
||
for filenames,
|
||
e.g.<tt><filename></tt>
|
||
foo.sgml
|
||
<tt></filename></tt>
|
||
produces: <tt>foo.sgml</tt>.
|
||
</p></li><li><p><a name="id2938391"></a> <tt><filename
|
||
class="directory"></tt> -- used for
|
||
directories, e.g.<tt><filename
|
||
class="directory"></tt>/usr/bin
|
||
<tt></filename></tt>
|
||
produces: <tt>/usr/bin</tt>.
|
||
</p></li><li><p><a name="id2938454"></a>
|
||
<tt><application></tt> -- used for
|
||
application names,
|
||
e.g. <tt><application></tt>Gnumeric
|
||
<tt></application></tt> produces:
|
||
Gnumeric.
|
||
</p></li><li><p><a name="id2938509"></a>
|
||
<tt><envar></tt> -- used for
|
||
environment variables, e.g.
|
||
<tt><envar></tt>PATH<tt></envar></tt>.
|
||
</p></li><li><p><a name="id2938551"></a>
|
||
<tt><command></tt> -- used for
|
||
commands entered on command line, e.g.
|
||
<tt><command></tt>make install
|
||
<tt></command></tt> produces:
|
||
<b>make install</b>.
|
||
</p></li><li><p><a name="id2938607"></a>
|
||
<tt><replaceable></tt> -- used for
|
||
replaceable text, e.g.
|
||
<tt><command></tt>db2html<tt><replaceable></tt>
|
||
foo.sgml
|
||
<tt></replaceable></tt><tt></command></tt>
|
||
produces: <b>db2html
|
||
<i><tt>foo.sgml</tt></i></b>.
|
||
</p></li></ul></div></div><div class="sect3"><a name="keys"></a><div class="titlepage"><div><h4 class="title"><a name="keys"></a>Keyboard input</h4></div></div><p> To mark up text input by the user, use
|
||
<tt><userinput></tt>.
|
||
</p><p> To mark keystrokes such as shortcuts and other
|
||
commands, use <tt><keycap></tt>.
|
||
This is used for marking up what is printed on the top
|
||
of the physical key on the keyboard. There are a couple of
|
||
other tags for keys, too: <tt><keysym></tt>
|
||
and <tt><keycode></tt>. However you are
|
||
unlikely to need these for most documentation. For reference,
|
||
<tt><keysym></tt> is for the “symbolic
|
||
name” of a key. <tt><keycode></tt> is
|
||
for the “scan code” of a key. These are not
|
||
terms commonly required in GNOME documentation,
|
||
although <tt><keysym></tt> is useful for marking
|
||
up control codes.
|
||
</p><p>
|
||
To mark up a combination of keystrokes, use the
|
||
<tt><keycombo></tt> wrapper:
|
||
<pre class="programlisting">
|
||
|
||
<keycombo>
|
||
<keycap>Ctrl</keycap>
|
||
<keycap>Alt</keycap>
|
||
<keycap>F1</keycap>
|
||
</keycombo>
|
||
</pre>
|
||
</p><p>
|
||
Finally, if you want to show a shortcut for some menu
|
||
command, here are the appropriate tags (rather long):
|
||
<pre class="programlisting">
|
||
|
||
<menuchoice>
|
||
<shortcut>
|
||
<keycombo><keycap>Ctrl</keycap><keycap>q</keycap></keycombo>
|
||
</shortcut>
|
||
<guimenuitem> Quit</guimenuitem>
|
||
</menuchoice>
|
||
</pre>
|
||
which produces simply
|
||
Quit (<b>Ctrl-q</b>)
|
||
</p></div><div class="sect3"><a name="email"></a><div class="titlepage"><div><h4 class="title"><a name="email"></a>E-mail addresses</h4></div></div><p> To mark up e-mail
|
||
address, use <tt><email></tt>:
|
||
<pre class="programlisting">
|
||
The easiest way to get in touch with me is by e-mail
|
||
(<email>me@mydomain.com</email>)
|
||
</pre>
|
||
which produces: The easiest way to get in touch with me is
|
||
by e-mail (<tt><<a href="mailto:me@mydomain.com">me@mydomain.com</a>></tt>) Note that
|
||
<tt><email></tt> automatically produces a link
|
||
in html version.
|
||
</p></div><div class="sect3"><a name="specsymb"></a><div class="titlepage"><div><h4 class="title"><a name="specsymb"></a> Special symbols </h4></div></div><p>
|
||
DocBook also provides special means for entering
|
||
typographic symbols which can not be entered directly
|
||
form the keyboard (such as copyright sign). This is done using
|
||
<i>entities</i>, which is SGML analogue of
|
||
macros, or commands, of LaTeX. They generally have the form
|
||
<tt>&entityname;</tt>. Note that the semicolon
|
||
is required.
|
||
</p><p>
|
||
here is partial list of most commonly used enitites:
|
||
</p><div class="itemizedlist"><ul><li><p><a name="id2939068"></a>
|
||
<tt>&amp;</tt> -- ampersend (&)
|
||
</p></li><li><p><a name="id2939089"></a>
|
||
<tt>&lt;</tt> -- left angle bracket (<)
|
||
</p></li><li><p><a name="id2939108"></a>
|
||
<tt>&copy;</tt> -- copyright sign (©)
|
||
</p></li><li><p><a name="id2939126"></a>
|
||
<tt>&mdash;</tt> -- long dash (--)
|
||
</p></li><li><p><a name="id2939152"></a>
|
||
<tt>&hellip;</tt> -- ellipsis (...)
|
||
</p></li></ul></div><p>
|
||
Note that the actual look of the resulting symbols depends
|
||
on the fonts used by your browser; for example, it might
|
||
happen that long dash (<tt>&mdash;</tt>) looks
|
||
exactly like the usual dash (-). However, in the PostScript
|
||
(and thus, in print) the output will look markedly better if
|
||
you use appropriate tags.
