31  <title>Write documentation</title>
32  <para>
33    This chapter is for those who intent to contribute to the BASE2 documentation. The chapter
34    contains explanations of how the documentation is organized, what the different parts is
35    about and other things that will make it easier to know where to insert new text.
36  </para>
37  <para>
38    The documentation is written with the docbook standard, which is a bunch of defined XML
39    elements and XSLT style sheets that are used to format the text. Later on in this chapter
40    is a reference, over those docbook elements that are recommended to use when writing BASE2
41    documentation. Further information about docbook can be found in the on-line version of
42    O'Reilly's
43    <ulink url="http://www.docbook.org/tdg/en/html/">DocBook: The Definitive Guide</ulink>

49    <para>
50      The book, which is the main element in this docbook documentation, is divided into four
51      separated parts, depending on who the information is directed to. What kind of
52      documentation each one of these parts contains or should contain is described here
53      below.

59          <para>
60            The overview part contains, like the name says, an overview of BASE2.
61            For example an explanation about what the purpose with BASE2 is, the terms
62            that are used in the program and other general things that anyone that is
63            interested in the program wants/needs to know before exploring it further.

104      Before start writing any documentation in BASE2 there are a couple of things, some
105      rules and standards, to have in mind.

110        The source files of the documentation are located in

112        which is showed in
113        <xref linkend="write_docbook_doc.figures.fileorganization" />
114        . The different parts of the documentation are organized into separate folders and
115        each one of the folders contains one index file and one file for each chapter in
116        that part. The index file joins the chapters, in current part/folder, together and
117        doesn't really contain any text. The documentation root directory also contains an
118        <filename class='headerfile'>index.xml</filename>
119        file which joins the index files from the different parts together.

199                Next and last step is to get the new chapter included in the documentation. This is done by including the file's name in

202                that's located in the current part's folder.

245    <sect2 id="write_docbook_doc.begin.chunking">
246      <title>Controlling chunking</title>
247      <para>
248        We have configured docbook to create a new output file for
249        each new <sgmltag class="starttag">chapter</sgmltag>
250        and <sgmltag class="starttag">sect1</sgmltag>. In most cases this
251        gives each page a relatively good size. Not too long and not too short.
252        However, if a chapter contains many small <sgmltag class="starttag">sect1</sgmltag>
253        sections (for example, <xref linkend="resources"/>), you end up with many
254        pages with just a few lines of text on each page. This is not so
255        good and can be avoided by adding a <sgmltag class="attribute">chunked = "0"</sgmltag>
256        attribute to the chapter, for example:
257      </para>
258      <programlisting>
259&lt;chapter id="resources" chunked="0"&gt;
260</programlisting>
261      <para>
262        This will stop the chunking of <sgmltag class="starttag">sect1</sgmltag>
263        sections in this chapter. On the other
264        hand, if you have a <sgmltag class="starttag">sect1</sgmltag>
265        that contains many long <sgmltag class="starttag">sect2</sgmltag>
266        sections you might want to put each <sgmltag class="starttag">sect2</sgmltag>
267        section in a separate chunk. If you want to do this:
268      </para>
269      <programlisting>
270&lt;sect1 id="sect.with.large.sect2" chunked="1"&gt;
271</programlisting>

279        attribute
280      </title>
281      <para>
282        Common to all elements is that they have an id attribute that can have an unique value to identify the
283        element with. Most of the elements that are used inside the BASE2 documentation don't
284        need to have an id if they don't are used in any cross references from other part of
285        the text.

287      <para>
288        There are however some elements that always should have the
289        <sgmltag class="attribute">id</sgmltag>
290        set. Which these elements are and how the
291        <sgmltag class="attribute">id</sgmltag>
292        should look like for each one of those is described below. All ids should be as
293        short as possible and associated to the current element. The
294        <sgmltag class="attribute">id</sgmltag>
295        value should only consist of the lowercase characters a-z, '_' instead of blank
296        spaces and '.' to symbolize the different levels in the document.

380                BASE2's web client already has several IDs to help texts defined,
381                it could therefore be a good idea to have a look in the

432          From time to time, it may happen that you find that
433          some parts of the text inside a <sgmltag class="starttag">helptext</sgmltag>
434          tag doesn't make sense. It may, for example, be a reference to
435          an image or an example, or a link to another chapter or
436          section. Put a <sgmltag class="starttag">nohelp</sgmltag>
437          tag around the problematic part to avoid it from beeing

499          Those who have checked out the documentation source from repository or got the
500          source from a distribution package needs to compile it to get the pdf and html
501          documentation files. The compilation of the documentation source requires, beside Ant, that the XML-parser
502          Xsltproc is installed on the local computer. XsltProc and how it is installed, can
503          be found at
504          <ulink url="http://xmlsoft.org/XSLT/index.html"></ulink>.

507          <para>
508            There is an xml-parser in newer java-versions that can be used instead of
509            XsltProc but the compilation will most likely take much much longer time.
510            Therefore it's not recommended to be used when generating/compiling the
511            documentation in BASE 2.

518          There are two different types of format that is generated from the documentation

520          chunked HTML pages where each chapter and section of first level are on separate
521          pages/files. The other format is a PDF-file that are most useful for printing
522          and distribution. Those two types of output are generated with the ant-target:
523          <command>ant docbook</command>
524          . This documentation is also generated with
525          <command>ant dist</command>
526          , which will put the output files in the right location for distribution with
527          BASE 2.
