Documentation Authoring</A ></H1 ><P > <ACRONYM CLASS="ACRONYM" >SGML</ACRONYM > and <SPAN CLASS="PRODUCTNAME" >DocBook</SPAN > do not suffer from an oversupply of open-source authoring tools.

On some systems these tools are provided in a typical full installation. </P ><DIV CLASS="SECT2" ><H2 CLASS="SECT2" ><A NAME="AEN155422" >J.4.1. Emacs/PSGML</A ></H2 ><P > <SPAN CLASS="PRODUCTNAME" >PSGML</SPAN > is the most common and most powerful mode for editing <ACRONYM CLASS="ACRONYM" >SGML</ACRONYM > documents. When properly configured, it will allow you to use <SPAN CLASS="APPLICATION" >Emacs</SPAN > to insert tags and check markup consistency. You could use it for <ACRONYM CLASS="ACRONYM" >HTML</ACRONYM > as well. Check the <A HREF="http://www.lysator.liu.se/projects/about_psgml.html" TARGET="_top" > PSGML web site</A > for downloads, installation instructions, and detailed documentation. </P ><P > There is one important thing to note with <SPAN CLASS="PRODUCTNAME" >PSGML</SPAN >: its author assumed that your main <ACRONYM CLASS="ACRONYM" >SGML</ACRONYM > <ACRONYM CLASS="ACRONYM" >DTD</ACRONYM > directory would be <TT CLASS="FILENAME" >/usr/local/lib/sgml</TT >. If, as in the examples in this chapter, you use <TT CLASS="FILENAME" >/usr/local/share/sgml</TT >, you have to compensate for this, either by setting <TT CLASS="ENVAR" >SGML_CATALOG_FILES</TT > environment variable, or you can customize your <SPAN CLASS="PRODUCTNAME" >PSGML</SPAN > installation (its manual tells you how). </P ><P > Put the following in your <TT CLASS="FILENAME" >~/.emacs</TT > environment file (adjusting the path names to be appropriate for your system): </P><PRE CLASS="PROGRAMLISTING" >; ********** for SGML mode (psgml) (setq sgml-omittag t) (setq sgml-shorttag t) (setq sgml-minimize-attributes nil) (setq sgml-always-quote-attributes t) (setq sgml-indent-step 1) (setq sgml-indent-data t) (setq sgml-parent-document nil) (setq sgml-exposed-tags nil) (setq sgml-catalog-files '("/usr/local/share/sgml/catalog")) (autoload 'sgml-mode "psgml" "Major mode to edit SGML files." t )</PRE ><P> and in the same file add an entry for <ACRONYM CLASS="ACRONYM" >SGML</ACRONYM > into the (existing) definition for <TT CLASS="VARNAME" >auto-mode-alist</TT >: </P><PRE CLASS="PROGRAMLISTING" >(setq auto-mode-alist '(("\\.sgml$" . sgml-mode) ))</PRE ><P> </P ><P > You might find that when using <SPAN CLASS="PRODUCTNAME" >PSGML</SPAN >, a comfortable way of working with these separate files of book parts is to insert a proper <TT CLASS="LITERAL" >DOCTYPE</TT > declaration while you're editing them. If you are working on this source, for instance, it is an appendix chapter, so you would specify the document as an <SPAN CLASS="QUOTE" >"appendix"</SPAN > instance of a DocBook document by making the first line look like this: </P><PRE CLASS="PROGRAMLISTING" ><!DOCTYPE appendix PUBLIC "-//OASIS//DTD DocBook V4.2//EN"></PRE ><P> This means that anything and everything that reads <ACRONYM CLASS="ACRONYM" >SGML</ACRONYM > will get it right, and I can verify the document with <TT CLASS="COMMAND" >nsgmls -s docguide.sgml</TT >.
