+The chemscheme package - Support for chemical schemes

+The chemscheme package consists of two parts, both related to
+chemical schemes.  The package adds a scheme float type to the
+LaTeX default types figure and table. The scheme float type
+acts in the same way as those defined by the LaTeX kernel, but
+is intended for chemical schemes.  The package also provides a
+method for adding automatic chemical numbering to schemes.

+%
+% The |chemscheme| package consists of two parts, both related to
+% chemical schemes.  The package adds a |scheme| float type to the
+% LaTeX default types |figure| and |table|. The |scheme| float type
+% acts in the same way as those defined by the LaTeX kernel,  but is
+% intended for chemical schemes.  The package also provides a method
+% for adding automatic chemical numbering to schemes.
+%
+% \end{abstract}
+%
+% \section{Introduction}
+%
+% By default, LaTeX defines two float types, |figure| and |table|.
+% Synthetic chemists make heavy use of schemes, which need a |scheme|
+% float type.  This is provided by |chemscheme|, in a manner
+% consistent with the kernel floats.
+%
+% Synthetic chemists also number compounds for ease of reference.
+% There are a number of LaTeX packages which cover this area, most
+% notably |bpchem| and |chemcompounds|.  However, adding numbers
+% automatically to schemes is not covered by any existing package.
+% The |chemescheme| package seeks to rectify this.
+%
+% \section{Floating schemes}
+%
+% \subsection{Basic use}
+%
+% \DescribeEnv{scheme}
+% The package provides a new float type, scheme, accessed in the
+% usual way.  So, issuing the following commands:
+% \begin{scheme}[ht]
+%   \centering
+%   \includegraphics{scheme-one}\\
+%   \caption{A scheme with no compound numbers.}
+%   \label{scheme-one}
+% \end{scheme}
+% \begin{verbatim}
+% \begin{scheme}[ht]
+%   \centering
+%   \includegraphics{scheme-one}\\
+%   \caption{A scheme with no compound numbers.}
+%   \label{scheme-one}
+% \end{scheme}
+% \end{verbatim}
+% will lead to the appearance of a scheme as requested
+% (Scheme~\ref{scheme-one}). By default, the positioning of |scheme|
+% floats follows the standard LaTeX system (positioning at the top
+% of a page is preferred). As shown in the example, the use of
+% positional modifiers is allowed. The |float| package is loaded by
+% |chemscheme|, allowing the use of the |[H]| positional directive,
+% meaning \emph{really} here.\footnote{|memoir| users should note
+% that |float| cannot be used with this document class.  The internal
+% |memoir| system for float placement is thus in use in this case.}
+% Labelling and referencing schemes follows the LaTeX conventions.
+% So for example, to reference Scheme~\ref{scheme-one}, you type
+% \begin{verbatim}
+% Scheme~\ref{scheme-one}
+% \end{verbatim}
+%
+% \DescribeMacro{\listofschemes}
+% To match the \cmd{\listoffigures} and \cmd{\listoftables} macros
+% provided by the LaTeX kernel, |chemscheme| provides a
+% \cmd{\listofschemes} command.  This works in the same way as the
+% kernel commands, taking a single optional argument \oarg{Title},
+% which by default is ``List of Schemes.''  The output of the
+% \cmd{\listofschemes} command is illustrated below.
+% \listofschemes
+%
+% \subsection{Altering the defaults}
+%
+% For users of the standard class files or the \textsc{koma-script}
+% bundle, the |float| package is used to create the new float type.
+% Thus the usual |float| commands can be used to modify the behaviour
+% as desired. Users of |memoir| will have slightly different commands
+% available, as |memoir| implements its own new float mechanism,
+% which is used in that case. Schemes may be numbered within chapters
+% (Scheme~1.1, Scheme~1.2, \emph{etc.}~by loading the package with the
+% [chapter] option.
+%
+% \DescribeMacro{\schemename}
+% \DescribeMacro{\listschemes}
+% Two macros are provided to allow the user to re-define the name of
+% schemes and the title of the list of schemes in a consistent manner
+% (independent of document class).  Thus \cmd{\schemename} contains
+% the text used in scheme captions (by default \schemename), and
+% \cmd{\listschemes} contains the title of the scheme list (by
+% default \listschemes).  Both may be freely re-defined.
+%
+% \section{Reference numbers in graphics}
+%
+% \subsection{Background}
+%
+% There are a number of packages available on \textsc{ctan} for
+% tracking compound reference numbers.  The two with the most up to
+% date and comprehensive features are |bpchem| and |chemcompounds|.
+% Both allow in-text numbering to be handled automatically.  However,
+% neither will allow the use of these numbers directly in schemes,
+% figures, \emph{etc.}  Both leave it to the user to manually
+% adapt schemes to match any changes in numbering.
+%
+% The |chemscheme| package provides a mechanism for rectifying this
+% issue, provided that \emph{compilation occurs in LaTeX (DVI) mode
+% and not using pdfLaTeX}.\footnote{Of course, both may be using the
+% pdfTeX engine; it is the output mode that is important.}
+%
+% \subsection{Usage}
+%
+% Getting automated numbers into schemes is a two step procedure. In
+% the first step, schemes (or other graphics) should be prepared as
+% normal and saved as encapsulated postscript (\textsc{eps}) files
+% The most popular chemistry drawing package, \textsc{ChemDraw},
+% is able to do this from the \texttt{Save As \ldots} dialog.
+% \DescribeMacro{\chemschemerefmarker}
+% The positions where the auto-labels should be positioned have to be
+% marked in the \textsc{eps} file.  The marker should consist of an
+% ``indicator'' that the text is to be replaced, followed by a
+% reference number or letter.  The ``indicator'' text should be the
+% same in all graphics; it is stored in \cmd{\chemschemerefmarker},
+% and has default value \textsf{\chemschemerefmarker}.  Thus the
+% graphics should contain labels \textsf{\chemschemerefmarker1},
+% \textsf{\chemschemerefmarker2}, \emph{etc.} A suitable unmodified
+% graphic is shown in Scheme~\ref{scheme-two-uned}.
+% \begin{scheme}[ht]
+%   \centering
+%   \includegraphics{scheme-two}\\
+%   \caption{A scheme with temporary compound numbers.}
+%   \label{scheme-two-uned}
+% \end{scheme}
+%
+% The value of \cmd{\chemschemerefmarker} may be altered as normal
+% using \cmd{\renewcommand}, so for example to use \textsf{XXX}
+% as the indicator for replacement, you would execute
+% |\renewcommand{\chemeschemerefmarker}{XXX}|.
+%
+% \DescribeMacro{\chemschemeref}
+% In the second step, the command \cmd{\chemschemeref} is used to
+% indicate the mapping of the temporary markers to the
+% automatically-managed numbering. The syntax of the command
+% is \cmd{\chemschemeref}\marg{temp-marker}\marg{label}, where
+% \meta{temp-marker} is the unique marker used in the graphic,
+% and \meta{label} is the name assigned to the compound by the user.
+% Each replacement requires a separate \cmd{\chemschemeref}, all
+% of which should appear before the relevant \cmd{\includegraphics}
+% command.  Notice that \meta{temp-marker} only contains the
+% unique part of the temporary marker. Thus using the default
+% indicator \textsf{\chemschemerefmarker}, the \textsc{eps} file
+% might contain \textsf{\chemschemerefmarker1} and \meta{temp-marker}
+% would be \textsf{1}.
+%
+% An example will make usage clearer. In the example used in this
+% document, the starting material is given label |IMesHCl| and
+% the product is called |IMes|.  As is shown in
+% Scheme~\ref{scheme-two-uned}, in the \textsc{eps} file these are
+% labelled \textsf{TMP1} and \textsf{TMP2}, respectively. To relabel
+% these as \CNlabel{IMesHCl} and \CNlabel{IMes}, the following is
+% needed:
+% \begin{scheme}[ht]
+%   \centering
+%   \chemschemeref{1}{IMesHCl}
+%   \chemschemeref{2}{IMes}
+%   \includegraphics{scheme-two}\\
+%   \caption{A scheme with automated compound numbers.}
+%   \label{scheme-two}
+% \end{scheme}
+% \begin{verbatim}
+% \begin{scheme}[ht]
+%   \centering
+%   \chemschemeref{1}{IMesHCl}
+%   \chemschemeref{2}{IMes}
+%   \includegraphics{scheme-two}\\
+%   \caption{A scheme with automated compound numbers.}
+%   \label{scheme-two}
+% \end{scheme}
+% \end{verbatim}
+% It is important to notice that the chemical labels must be defined
+% \emph{before} the use of \cmd{\chemschemeref}, or odd things may
+% happen (most likely your document will not compile with strange
+% errors). Also notice that the new label is centred on the middle of
+% the temporary marker, with the same baseline.  This should allow
+% the user to obtain good alignment of labels and structures.
+%
+% \DescribeMacro{\chemschemerefsub}
+% As described in Section~\ref{packages}, |chemscheme| supports
+% |bpchem|, which allows tracking of sub-labels (\textbf{1a},
+% \textbf{1b}, \emph{etc.}).  To allow use of these in schemes,
+% the \cmd{\chemschemerefsub} command is provided.  This takes an
+% additional argument \marg{sub-label}, which is used to generate
+% the appropriate text.  When used with |chemcompounds|, this command
+% will gobble its arguments and issue a warning; no substitution will
+% take place.
+%
+% \DescribeMacro{\chemschemerefformat}
+% The format of chemical references is controlled by the underlying
+% package, |bpchem| or |chemcompounds|.  However, it is useful to
+% be able to specify additional formatting for schemes.  By default,
+% |chemscheme| formats all reference numbers in a sans serif font.
+% This is controlled by \cmd{\chemschemerefformat}. The additional
+% formatting applied within schemes may be altered by redefining
+% \cmd{\chemschemerefformat}.  By careful choice of the font commands
+% given here, good visual matching should be obtained between the
+% automatically-generated labels and other text in the scheme.  In
+% this document, the \textsc{ChemDraw} source uses 10 point Arial,
+% with the LaTeX sans serif font provided by the |helvet| package,
+% loaded scaled to 95\percent, \emph{i.e.}
+% \begin{verbatim}
+% \usepackage[scaled=0.95]{helvet}
+% \end{verbatim}
+% The \textsc{ChemDraw} file used to generate the example schemes
+% is included with the package, as |chemscheme.cdx|.
+%
+% \subsection{Managing chemical numbering\label{packages}}
+%
+% The |chemscheme| package can use one of two packages for management
+% of chemical numbering.  Both |bpchem| and |chemcompounds| are
+% supported: |bpchem| is the default, and |chemcompounds| is requested
+% by loading |chemescheme| with the [chemcompounds] option.  Both
+% packages have advantages: |bpchem| allows the tracking of
+% sub-references (very common in organic chemistry), whilst
+% |chemcompounds| has a very well thought-out interface.  It is
+% technically feasible to support both simultaneously, but this is
+% unlikely to have wide application. For this reason, |chemscheme|
+% loads only one package (depending on the user option given), and
+% uses this package to provide numbering management.
+%
+% Both |bpchem| and |chemcompounds| provide a variety of methods for
+% defining chemical labels.  In either case, the user should define
+% the chemical label \emph{before} it is referenced by
+% \cmd{\chemschemeref}.  Errors are very likely to occur if this is
+% not done.
+%
+% \section{Known issues}
+%
+% The number replacement code relies on the use of |psfrag|, which
+% can only be applied to \textsc{eps} graphics.  Thus, users of
+% pdfLaTeX will not benefit form the automated number replacement.
+% For final compilation directly to \textsc{pdf}, it may be
+% preferable to modify the graphics files and use |epstopdf| to
+% include the files. The alternative is to use the more
+% traditional route \textsc{dvi} $\to$ \textsc{ps} $\to$
+% \textsc{pdf}.
+%
+% Currently, the names of schemes are only available in English. If
+% the correct translations are provided, the package author will
+% aim to incorporate the appropriate code.

+% \section{Implementation}
+%
+% \subsection{Setup code}
+%
+% The initial code goes through the usual steps of identifying the
+% package.
+%    \begin{macrocode}
+\NeedsTeXFormat{LaTeX2e}
+\ProvidesPackage{chemscheme}%
+  [2007/07/21 v1.0 Support for chemical schemes]
+%    \end{macrocode}
+% The |psfrag| package is required to carry out the inclusion of
+% chemical numbers in graphics.  If the |memoir| package is not
+% being used, the |float| package is used to provide support for
+% new float types.  However, if |memoir| is in use, |float| should
+% not be loaded.
+%    \begin{macrocode}
+\RequirePackage{psfrag}
+\@ifclassloaded{memoir}{}
+  {\RequirePackage{float}}
+%    \end{macrocode}
+% Option processing now takes place.  This requires two Boolean
+% values, which are declared here.  By default, |chemscheme| uses
+% |bpchem| for managing chemical compound references.  The options
+% reflect this.
+%    \begin{macrocode}
+\newif  \ifCHEMSCH@chapter   \CHEMSCH@chapterfalse
+\newif  \ifCHEMSCH@bpchem    \CHEMSCH@bpchemtrue
+\DeclareOption{chapter}{\global\CHEMSCH@chaptertrue}
+\DeclareOption{chemcompounds}{\global\CHEMSCH@bpchemfalse}
+\DeclareOption{bpchem}{}
+\ProcessOptions
+%    \end{macrocode}
+%
+% \subsection{Support for schemes}
+%
+% \begin{macro}{\schemename}
+% \begin{macro}{\listschemes}
+% The new float type for schemes in produced using the |float|
+% package, or the appropriate |memoir| code. First, names for
+% schemes and the list of schemes are set up.  These are provided
+% for ease of modification, as demonstrated in the |memoir| manual.
+%    \begin{macrocode}
+\newcommand*{\schemename}{Scheme}
+\newcommand*{\listschemes}{List of Schemes}
+%    \end{macrocode}
+% \end{macro}
+% \end{macro}
+% \begin{environment}{scheme}
+% The \cmd{\newfloat} command is used to generate the new float type,
+% first checking if numbering within chapters is requested.  A
+% suitable warning is issued if no chapters exist in the document.
+% The syntax required depends on whether |float| or |memoir| is used
+% for the definition.
+%    \begin{macrocode}
+\ifCHEMSCH@chapter
+  \ifx\chapter\@undefined
+    \PackageWarning{chemscheme}%
+      {No chapters in this document \MessageBreak%
+       Ignoring `chapter' option}
+       \@ifclassloaded{memoir}
+         {\newfloat{scheme}{los}{\schemename}}
+         {\newfloat{scheme}{tbp}{los}}
+  \else
+    \@ifclassloaded{memoir}
+      {\newfloat[chapter]{scheme}{los}{\schemename}}
+      {\newfloat{scheme}{tbp}{los}[chapter]}
+  \fi
+\else
+  \@ifclassloaded{memoir}
+    {\newfloat{scheme}{los}{\schemename}}
+    {\newfloat{scheme}{tbp}{los}}
+\fi
+%    \end{macrocode}
+% \end{environment}
+% \begin{macro}{\listofschemes}
+% To ensure that things are labelled correctly, the new float type
+% is given an appropriate name.  Notice that |memoir| does this at
+% the float-definition stage. In common with the standard float
+% types, a \cmd{\listof} command is provided for schemes.
+%    \begin{macrocode}
+\@ifclassloaded{memoir}
+  {\newlistof{listofschemes}{los}{\listschemes}}
+  {\floatname{scheme}{\schemename}
+    \newcommand*{\listofschemes}[1][\listschemes]%
+      {\listof{scheme}{#1}}}
+%    \end{macrocode}
+% \end{macro}
+%
+% \subsection{Reference numbers in graphics}
+%
+% \begin{macro}{\chemschemerefmarker}
+% \begin{macro}{\chemschemerefformat}
+% The two macros \cmd{\chemschemerefmarker} and
+% \cmd{\chemschemerefformat} are used to allow customisation of the
+% behaviour of the package.  Here defaults are provided.
+%    \begin{macrocode}
+\newcommand{\chemschemerefmarker}{TMP}
+\newcommand{\chemschemerefformat}{\textsf}
+%    \end{macrocode}
+% \end{macro}
+% \end{macro}
+% \begin{macro}{\CHEMSCH@label}
+% Depending on the user options provided, either |bpchem| or
+% |chemcompounds| is loaded to manage chemical citations.  The
+% macro \cmd{\CHEMSCH@label} is defined as the labelling command of
+% the appropriate package.
+%    \begin{macrocode}
+\ifCHEMSCH@bpchem
+  \RequirePackage{bpchem}
+  \let\CHEMSCH@label\CNlabel
+\else
+  \RequirePackage{chemcompounds}
+  \let\CHEMSCH@label\compound
+\fi
+%    \end{macrocode}
+% \end{macro}
+% \begin{macro}{\chemschemeref}
+% The referencing macro is a wrapper for the appropriate
+% \cmd{\psfrag} command.  The first argument of \cmd{\chemschemeref}
+% is the temporary code assigned to a compound, with the second
+% containing the reference used for the compound in the citation
+% scheme.  The use of |[b][b]| places the new label at the centre of
+% the position of the temporary one, at the same vertical position.
+%    \begin{macrocode}
+\newcommand{\chemschemeref}[2]{%
+  \psfrag{\chemschemerefmarker#1}[b][b]%
+  {\chemschemerefformat{\CHEMSCH@label{#2}}}%
+}
+%    \end{macrocode}
+% \end{macro}
+% \begin{macro}{\chemschemerefsub}
+% The |sub| version of the referencing command is needed as |bpchem|
+% allows tracking of sub-compounds (\emph{e.g.}~\textbf{1a},
+% \textbf{1b}, \emph{etc.}).  As |chemcompounds| does not do this,
+% the command in that case gobbles up the third argument and gives
+% the user a suitable warning.
+%    \begin{macrocode}
+\ifCHEMSCH@bpchem
+  \newcommand{\chemschemerefsub}[3]{%
+    \psfrag{\chemschemerefmarker#1}[b][b]%
+    {\chemschemerefformat{\CNlabelsub{#2}{#3}}}%
+  }
+\else
+  \newcommand{\chemschemerefsub}[3]{%
+    \PackageWarning{chemscheme}%
+    {`chemcompound' option active\MessageBreak
