% \section{Introduction}
%
% The \Lpack{iso4ht} package can be used in conjunction with
% the \texht{} system to convert \LaTeX{} \Lpack{iso} class documents
% into HTML tagged documents. The \Lpack{iso} class is for typesetting
% ISO standard documents~\cite{PRW96i}.
%
% Section~\ref{sec:usc} describes the package and
% commented source code for the package is in Section~\ref{sec:code}.
%
% This manual is typeset according to the conventions of the
% \LaTeX{} \textsc{docstrip} utility which enables the automatic
% extraction of the \LaTeX{} macro source files~\cite{GOOSSENS94}.
%
% \subsection{Acknowledgement}
%
% Development of the \Lpack{iso4ht} package would not have been possible
% without the help and expertise of Eitan Gurari, and in particular his
% willingness to put up with the many questions I asked.
%
%
% \section{The \Lpack{iso4ht} package} \label{sec:usc}
%
% The \texht{} system has been developed by Eitan Gurari (see Chapter~4
% and Appendix~B in~\cite{GOOSSENS99}. It is a general purpose conversion
% system to convert \LaTeX{} tagged documents into HTML (or other *ML)
% tagged documents. \texht{} can be obtained from
% \url{http://www.cis.ohio-state.edu/~gurari/TeX4ht/mn.html}.
% The \Lpack{iso4ht}
% package is not guaranteed to work with versions of \texht{} earlier
% than mid-January 2000. At the time of writing, the default \texht{}
% distribution was dated mid-1999. The latest version of \texht{} is obtainable
% from \url{http://www.cis.ohio-state.edu/~gurari/TeX4ht/bugfixes.html}.
%
% To use the \Lpack{iso4ht} package, just process the \LaTeX{} document
% as you would any other under \texht. That is, either call the |ht| script
% a document starting like:
% \begin{verbatim}
% \documentclass[...]{isov2}
% \usepackage[...]{tex4ht}
% ...
% \end{verbatim}
% or call the |htlatex| script on a document without the
% |\usepackage[...]{tex4ht}| line.
%
%
% \section{The package code} \label{sec:code}
%
% The following code is based on \Lpack{article.4ht}, \Lpack{html0.4ht},
% \Lpack{html32.4ht} and \Lpack{html4.4ht}, all written by Eitan Gurari.
%
% Most of the necessary work already exists in \Lpack{latex.4ht}, which
% sets up the \LaTeX{} kernel code. \Lpack{article.4ht} provides the
% setup for the \Lpack{article} class, and \Lpack{html0.4ht},
% \Lpack{html32.4ht} and \Lpack{html4.4ht} provide the HTML option-related
% configurations.
%
% The \Lpack{iso} class was originally based on the \Lpack{article} class,
% so \Lpack{isov2.4ht} is in turn based on \Lpack{article.4ht} (although little
% code is actually reused). The HTML option-related configurations are
% embedded in \Lpack{isov2.4ht} instead of being supplied as seperate files.
%
% \changes{v0.1}{2000/01/20}{First public release}
%
% Announce the name and version of the package.
% \begin{macrocode}
%<*usc>
\typeout{[isov2.4ht 2000/01/20 version v0.1]}
% \end{macrocode}
%
% \subsection{Setup and hooks}
%
% The first major part of the code deals with setting up for configuring
% the \LaTeX{} commands and environments, which forms the second major
% portion of the code.
%
% Setting up may involve adding hooks into commands, either by redefining
% them or, in simpler cases prepending and/or appending code before and/or
% after the original code. It can also involve specifying that commands
% are configurable.
%
% \subsubsection{Table of contents}
%
% What follows is a revised version of the \Lpack{article.4ht} setup
% for the |\tableofcontents|, |listoffigures| and |\listoftables| commands.
% Parctically all of the revision has to do with replacing \Lpack{article}
% sectioning commands (i.e., |\section|, |\subsection|, etc.)
% with the \Lpack{iso}
% sectioning commands (i.e., |\clause|, |\sclause|, etc.
%).

% \subsubsection{Sectioning commands}
%
% This part of the code provides the setup for the sectioning commands.
%
% For an ISO document, the Title comes after the ToC, Foreword and
% Introduction.\label{titlehooks}
% The \Lpack{iso} |\title| command should really end
% any previous sectioning commands, and the easiest way to manage this
% seems to be by redefining the |\title| command in terms of a sectioning
% command. In order to do this, some new commands are required and some
% \Lpack{iso} commands redefined.
%
% Eventually, it is the sectioning command that gets configured instead
% of the |\title| command.
% Another reason for doing things this way is that elsewhere, for
% a package under the \Lpack{iso} class, I will
% be configuring a different |\title| command and I will be able to use
% this as a basis for that configuration.
%
% \DescribeMacro{\introelement}
% \DescribeMacro{\compelement}
% These require redefining as, for reasons I don't understand, the system
% falls over when it tries to process the \Lpack{iso} |\isoemptystring|
% command. This is replaced by a more direct test.
% \begin{macrocode}
\renewcommand{\introelement}[1]{\ifx\empty#1\else {#1 ---\newline}\fi}
\renewcommand{\compelement}[1]{\ifx\empty#1\else { ---\newline #1}\fi}
% \end{macrocode}
%
% \DescribeMacro{\titleclause}
% A `clause' for typesetting (in \texht{} only) the title. This should make
% no entry in the ToC. There is no typeset number, so life is a bit simpler
% than when normally defining sectioning commands.
% \begin{macrocode}
\newcommand{\titleclause}{%
\@startsection{titleclause}{100}% large level to avoid adding to ToC
{\z@}%
{\beforecskip}%
{\aftercskip}%
{\raggedright\Tfont\bfseries}}
% \end{macrocode}
%
% \DescribeMacro{\title}
% Now redefine the original |\title| command in terms of |\titleclause*|.
% \begin{macrocode}
\renewcommand{\title}[3]{%
\setcounter{clause}{0}
\gdef\thetitle{\introelement{#1} %
\mainelement{#2} %
\compelement{#3}}
\titleclause*{\thetitle}}
% \end{macrocode}
%
% Do the |\title| `clause' hooks.

% \subsection{Observations}
%
% There are three main aspects to developing \texht{} code and
% configurations for a new class or package:
% \begin{enumerate}
% \item Finding out what hooks and configurations are already available.
% \item Determining what additional hooks, and where they should be put, for
% the new package.
% \item Configuring all the hooks.
% \end{enumerate}
%
% \texht{} has added many hooks to the \LaTeX{} kernel and classes
% and packages
% based on kernel code inherit those hooks. I found it advisable to run
% a test document with new macros through \texht{} to see what
% the result looked like. Depending on the particular macros it may be that
% the inherited hooks and configuration are sufficient and nothing needs
% to be done.
%
% For this particular class a lot of new hooks were required, but mainly
% related to the new macros for sectioning. Configurations were obviously
% required for these, together with a few for new kinds of environments
% and lists.
%
% There are other packages that, in their turn, are designed to work
% with the \Lpack{iso}
% class and it turned
% out that they required few new hooks or changes to the existing
% configurations.
%
% The rest of this section is concerned with item~2, namely
% adding hooks.
%
% \subsubsection{Colon is a letter}
%
% Within the \texht{} `environment', that is the \file{*.4ht}
% files, the colon character (|:|) acts as a letter in a similar manner
% as the at character (|@|) does in class and package files; |@| is also
% treated as a letter in the environment. Normally, something like
% |\start:env{myenv}| would be treated as the command |\start| followed by
% the text |:env{myenv}|. In the \texht{} environment it is the command
% |\start:env| with the argument |{myenv}|. If any commands like this
% occur in the preamble to a \LaTeX{} document, then they must be surrounded
% by |\makecolonletter| and |\restorecolon|, which may be defined
% as:\footnote{Note that a package may redefine the category code for
% the colon, which is why the old value is saved.}
% \begin{verbatim}
% \chardef\oldcolon=\thecatcode`\:
% \newcommand{\makecolonletter}{\catcode`\:11\relax}
% \newcommand{\restorecolon}{\catcode`\:=\oldcolon\relax}
% \end{verbatim}
%
% The fact that command names can include a colon means that you have
% to be careful in code that includes any colon characters. In \LaTeX,
% code like like |{footnote \thefootnote:}| will print the footnote number
% immediately followed by a colon (e.g., |footnote 3:|). In the \texht{}
% environment you are more likely to get an error message saying that
% |\thefootnote:| is undefined! Instead, this needs to be coded as
% |{footnote \thefootnote :}|, so that the |\thefootnote| command is ended
% by the space before the colon.
%
% \subsubsection{Adding code and hooks}
%
% A \LaTeX{} idiom for adding code at the start and/or end of
% an existing macro which takes no arguments called, say |\foo|, is:
% \begin{verbatim}
% \let\oldfoo\foo
% \renewcommand{\foo}{new-start-code \oldfoo new-end-code}
% \end{verbatim}
% Similarly for commands |\baz| and |\biz| which take one and two arguments
% respectively:
% \begin{verbatim}
% \let\oldbaz\baz
% \renewcommand{\baz}[1]{new-start-code \oldbaz{#1} new-end-code}
% \let\oldbiz\biz
% \renewcommand{\biz}[2]{new-start-code \oldbiz{#1}{#2} new-end-code}
% \end{verbatim}
%
% As these kinds of redefinitions are a common occurrence
% \file{tex4ht.sty} provides commands that encapsulate the above idiom.
% These are |\pend:def\foo{new-start-code}| and
% |\append:def\foo{new-end-code}| for when |\foo| is a macro without
% arguments, and there are similar commands for prepending and appending
% to macros with up to three arguments. Repeating and extending
% the \LaTeX{} example,
% in the \texht{} environment it could be coded as:
% \begin{verbatim}
% \pend:def\foo{new-start-code} % \foo has no arguments
% \append:def\foo{new-end-code}
% \pend:defI\baz{new-start-code} % \baz has one argument
% \append:defI\baz{new-end-code}
% \pend:defII\biz{new-start-code} % \biz has two arguments
% \append:defII\biz{new-end-code}
% \pend:defIII\boz{new-start-code} % \boz has three arguments
% \append:defIII\boz{new-end-code}
% \end{verbatim}
%
% The definition of a hook in a macro called, say |\buz|, takes
% the form |\X:buz| where X is a single letter. For example, adding a
% configurable hook
% at the start and end of the macro |\baz| can be done like this:
% \begin{verbatim}
% \pend:defI\baz{\a:baz} % hook at start
% \append:defI\baz{\b:baz} % hook at end
% \NewConfigure{baz}{2} % declare \baz has two configurable hooks
% \end{verbatim}
% Note that by default a |\NewConfigure{baz}{2}| command expects the hook
% corresponding to the first argument to be |\a:baz| and the hook
% corresponding to the second argument to be |\b:baz|. Extending the
% example, |\NewConfigure{foo}{9}| will expect the hook corresponding to
% the ninth argument to be |\i:foo| (`i' is the ninth letter of the
% alphabet). This default setting for |\NewConfigure| has been created via: \\
% |\Configure{NewConfigure}{a:}{b:}{c:}{d:}{e:}{f:}{g:}{h:}{i:}| \\
% in \file{tex4ht.sty}.
%
%
% As an example for hook insertion, assume a macro defined like: \\
% |\newcommand{\mac}[1]{START #1 END}| \\
% in which there are four potential places for hooks (call them h1 to h4): \\
% |{h1 START h2 #1 h3 END h4}|. Hooks h1 and h4 can be added via |\pend:defI|
% and |\append:defI|, but these are not sufficient by themselves. Other
% methods are required for inserting all four hooks. Two of these are:
% \begin{itemize}
% \item Redefine the whole macro from scratch:
% \begin{verbatim}
% \renewcommand{\mac}[1]{\a:mac START \c:mac #1 \d:mac END \b:mac}
% \NewConfigure{mac}{4}
% \end{verbatim}
%
% \item Reuse parts of the original macro
% (similar to the \LaTeX{} ap/pre-pending idiom):
% \begin{verbatim}
% \let\oldmac\mac
% \renewcommand{\mac}[1]{\a:mac\oldmac{\c:mac #1 \d:mac}\b:mac}
% \NewConfigure{mac}{4}
% \end{verbatim}
% \end{itemize}
% Either of these examples can be configured via:
% \begin{verbatim}
% \Configure{mac}%
% {first arg for a hook} % \a:mac at the start of the command
% {second arg for a hook} % \b:mac at the end of the command
% {third arg for a hook} % \c:mac immediately before the argument
% {fourth arg for a hook} % \d:mac immediately after the argument
% \end{verbatim}
% Note that the hooks do not have to be placed in the |\mac| command in
% alphabetical order.
