The motivating example +% is labeling chemical structures in a scientific document. +% +% \section{Usage} +% +% This package solves the problem of providing a sequence of numeric +% labels to represent entities in a document. The motivating example is +% labels for chemical structures in a scientific document. In such a +% document you want the full chemical name and a label to appear in the +% typeset document for each chemical structure the first time the +% structure is referenced in the document text. Subsequent references to +% the structure should only use the label. These labels should form a +% numeric sequence, with the first chemical structure being labeled +% \textbf{1}, the second \textbf{2} and so on. +% +% These labels share similar features to numeric bibliographic reference +% styles, both use numbers to represent something, the numbers form a +% single sequence starting from one and incrementing as references or +% structures appear in the document. Furthermore these labels or +% citations can appear in multiple places in the text but must retain a +% single unique numeric label. +% +% However there are a couple of differences to a bibliography. Firstly +% the name of the chemical structure generally appears where it is first +% used in the document along with its label rather than in a +% bibliography or footnote. Secondly it is common to use a single +% numeric label for closely related structures, appending a sub-label to +% denote individual structures, usually lower-case letters. For example +% we might have ``\textsf{methyl acetate (\textbf{1a})}'' and +% ``\textsf{ethyl acetate (\textbf{1b})}'' being specific examples of an +% ``\textsf{acetic acid ester (\textbf{1})}'' structure. Lastly, you may +% need to separate the logical and actual first occurrence of a label, +% allowing use of labels in abstracts and captions before a defining +% macro call that sets the actual number of the label in the main +% document sequence. +% +% The solution presented here uses keys to identify structures, in a +% similar way to the BibTeX, with a special format that allows +% associating related structures to an exemplar structure. This is +% achieved by using keys that contain an exclamation mark +% (|main-key!sub-key|) to separate the key for an exemplar structure +% from a sub-key for the related structures. Following our example above +% we might have keys |acetate!methyl|, |acetate!ethyl| and |acetate| as +% the keys for ``methyl acetate'', ``ethyl acetate'' and ``acetic acid +% ester'' respectively. Using such keys with this package would +% automatically give the labels ``\textsf{\textbf{1a}}'', +% ``\textsf{\textbf{1b}}'' and ``\textsf{\textbf{1}}''. Alternatively +% in chemistry we want the sub-labels to be more meaningful, for example +% denoting isomeric structures or an abbreviation for different +% substituents. This package allows you to manually provide such a more +% meaningful sub-label for each sub-key, for example leading to +% ``\textsf{methyl acetate (\textbf{1-Me})}'' and ``\textsf{ethyl +% acetate (\textbf{1-Et})}'' and ``\textsf{acetic acid ester +% (\textbf{1})}'' in the output document. + +% However, using sub-keys is entirely optional and you can write a +% complete document without using the sub-key feature. Keys with +% sub-keys can be freely mixed in a document with keys that do not have +% sub-keys. We suggest you generally want to provide an exemplar key +% without sub-key for each set of keys which have sub-keys. This allows +% you to refer in the document to the group of related chemicals as well +% as the specific structures, ``\textsf{acetic acid ester +% (\textbf{1})}'' in our example above. Hopefully the most difficult +% part of using the \textsf{chemsec} package is choosing keys for your +% structures. +% +% \subsection{Known Issues} +% +% \subsection{Capitalization of names} +% +% The package cannot capitalize the name of an entity, for example if an +% entity name appears at the beginning of a sentence. For example the +% capitalization of a chemical name requires parsing and understanding +% the complete chemical nomenclature, something well beyond the scope of +% this package. It is also hard to automatically detect when +% capitalization should occur. Currently, the solutions are to avoid +% using the macros that might produce entity names at the start of a +% sentence or to manually type the entity name and use a macro that only +% outputs a label. A possible future extension of this package may allow +% the specification of two names for a compound, one capitalized and one +% not, as well as macros to select between them. +% +% \subsubsection{Failure to issue warning} +% +% \emph{Note} that any labeling issue arising from this package is +% always resolved when the document is processed twice in a row. It is +% therefore recommended that, after making an edit, the user always +% processes the document twice to ensure correct labeling. +% +% The user should get a warning if the for some reason the labels +% typeset in the document are incorrect and the document processing +% needs to be repeated. This can happen when using a macro that +% requests the value of a label but does not set it. These macros use +% current values or values set in the \textsl{aux} file. If the values +% from the \textsl{aux} file need to be used they may either not be present +% or differ from values set later in the document. When this happens +% the user should get a warning message, however a number of issues may +% prevent this and it is always recommended to process the document twice +% after editing to ensure the correct labeling. +% +% Known cases of failure to get a warning message are: +% \begin{itemize} +% \item Use of macros before the document begins, for example in the +% \textsf{abstract} environment, may fail to issue a warning about +% incorrect labels. (I think this is due to the boolean variable that +% signals an error being reset at the beginning of the document.) +% \item Automatic sub-labels. Currently we cannot check to see if +% sub-labels change during document processing. This is because +% sub-labels are stored as text rather than numbers and text comparison +% is surprisingly difficult in LaTeX. +% \item User-defined sub-labels. We do not detect if a user-defined +% sub-label is defined after a request for the sub-label. This is only +% an issue the first time a document is processed or when a +% |\DefineChemical| macro command is added to the document. +% \end{itemize} +% +% \subsection{Defining structure names and sub-labels} +% +% \DescribeMacro{\DefineChemical} You define the names and optional +% sub-label of a compound or entity using the |\DefineChemical| +% \marg{key} \marg{name} \marg{sub-label} macro. This command does not +% display any output in the document nor does it define the first part +% of the label. This means you can define all the chemicals used in the +% document in a single place rather than as they appear in the document. +% The list can even be placed in a separate file included in the main +% file, facilitating the reuse of keys and names in other documents. No +% matter where this macro is placed in the document the \textsf{chemsec} +% package will use the information wherever needed. +% +% Leaving the \marg{sub-label} argument empty for a |main!sub| key turns +% on automatic sub-labeling for this key. By default this generates +% sequential alphabetic labels for each |sub| key with the same |main| +% key for which there is no user defined sub-label. This means that you +% can manually supply labels for some |main!sub| keys and also have +% |main!sub| keys without a defined label. This is advanced usage and +% this package does not check to see if the automatically generated +% labels match any of the user-defined labels. +% +% The \textsl{name} parameter can contain many LaTeX formatting +% commands, including the use of |$$| math-mode. +% +% \subsection{\textsf{ChemCite} Macros} +% +% The package provides a range of macros that tailor what information +% about a structure is output into the typeset document. These are the +% |ChemCite| family of macros. All of these macros can have a ``|*|'' +% (star) suffix. This suffix indicates this use of the macro should act +% as a cross-reference for the label and not as a possible defining +% reference. This means that the star form can be used in abstracts, +% captions and anywhere in the document you need to use a label where it +% might appear before it appears in the main document text where you +% want the numeric label to be defined. +% +% \DescribeMacro{\ChemCite\marg{key}} Output the label for the given +% key. If this is the first time the key is used and the non-star form +% is used the full name precedes the label, with a star no full name is used. For example +% |\ChemCite{acetate!methyl}| could give ``methyl acetate (\textbf{1a})'' +% the first time it appeared and ``\textbf{1a}'' elsewhere. +% The non-star form also sets the value of the numeric label at the +% point it first appears in the document. The star form uses in order; +% the current label if defined or a value stored in the \textsl{aux} +% file from the previous time the document was processed or a +% dummy value. The star form also never outputs the full name. For example +% |\ChemCite*{acetate!methyl}| could give ``\textbf{1a}'' if it can +% determine the labels or output a dummy value ``\textbf{0??}'' (or +% less likely ``\textbf{0a}'' or ``\textbf{1??}''). +% +% \DescribeMacro{\ChemFCite\marg{key}} This macro always displays the +% structure name as well as the label for the given key. The |F| is a +% mnemonic for \textsf{full}, indicating the full entry of the name and +% label is always used. For example |\ChemFCite{acetate!methyl}| would +% give ``methyl acetate (\textbf{1a})'' the first time it appeared as well +% as elsewhere. The non-star form also +% sets the value of the numeric label at the point it first appears in +% the document. The star form uses in order; the current label if +% defined or a value stored in the \textsl{aux} file from the previous +% time the document was processed or a dummy value. For example +% |\ChemFCite*{acetate!methyl}| could give ``methyl acetate +% (\textbf{1a})'' if it can determine the labels or output a dummy value +% ``?? (\textbf{0??})'' or similar. +% +% \DescribeMacro{\ChemSCite\marg{key}} In counterpoint to the +% |\ChemFCite| macro, this always only outputs the label for the given +% key. The |S| is a mnemonic for \textsf{short}, indicating the short +% entry of just the label is always used. For example +% |\ChemSCite{acetate!methyl}| would give ``\textbf{1a}'' the first time +% it appeared as well as ``\textbf{1a}'' elsewhere. The non-star form +% also sets the value of the numeric label at the point it first appears +% in the document. The star form uses in order; the current label if +% defined or a value stored in the \textsl{aux} file from the previous +% time the document was processed or a dummy value. For example +% |\ChemSCite*{acetate!methyl}| could give ``\textbf{1a}'' if it can +% determine the labels or output a dummy value ``\textbf{0??}'' (or less +% likely ``\textbf{0a}'' or ``\textbf{1??}''). +% +% \DescribeMacro{\ChemMFCite\marg{key}} This macro always displays the +% structure name of the main part of the key with the label for the +% given key. The |MF| is a mnemonic for \textsf{main full} or +% \textsf{mixed full}, indicating the full entry of the \textit{main} +% (exemplar) name is used with the label and sub-label for the key. For +% example |\ChemMFCite{acetate!methyl}| would give ``acetic acid ester +% (\textbf{1a})'' wherever it was used. The non-star form also sets the +% value of the numeric label at the point it first appears in the +% document. The star form uses in order; the current label if defined or +% a value stored in the \textsl{aux} file from the previous time the +% document was processed or a dummy value. For example +% |\ChemMFCite*{acetate!methyl}| could give ``acetic acid ester +% (\textbf{1a})'' if it can determine the labels or output a dummy value +% ``?? (\textbf{0??})'' or similar. +% +% \DescribeMacro{\ChemMSCite\marg{key}} This macro always displays just +% the label from the main part of the key. The |MS| is a mnemonic for +% \textsf{main short} or \textsf{mixed short}, indicating the short +% entry of just the \textit{main} (exemplar) label for the key. For +% example |\ChemMSCite{acetate!methyl}| would give ``\textbf{1}'' +% wherever it was used. While this macro always gives exactly the same +% result as |\ChemSCite| with just the main part of a key +% (e.g. |\ChemSCite{acetate}|), it is included here because it allows +% the document writer to include more context in the document as it is +% being written. The non-star form also sets the value of the numeric +% label at the point it first appears in the document. The star form +% uses in order; the current label if defined or a value stored in the +% \textsl{aux} file from the previous time the document was processed or +% a dummy value. For example |\ChemMSCite*{acetate!methyl}| could give +% ``\textbf{1}'' if it can determine the label or output a dummy value +% ``\textbf{0}''. +% +% \DescribeMacro{\NoCite\marg{key}} This macro outputs nothing in the +% document but sets the numeric value of the label for the key in the +% document ordered sequence. +% +% \subsection{Possible Future extensions} +% +% \DescribeMacro{\ChemEntityTable} Output a table of entity names, +% labels and keys. This is intended to be used for creating a useful +% reference table when creating and editing a document rather than for +% final output. +% +% \subsection{Internal macros that control style} +% +% Style macros can be overridden by the user to control the style of the +% label and accompanying text. +% +% \DescribeMacro{\ChemLabelStyle} Internal macro that formats a +% label. It is used by the other two style macros for this purpose. +% Users may redefine this macro to change the label formatting. +% +% \DescribeMacro{\ChemFullLabelStyle} Internal macro used to format a +% label and its full name text. Users may redefine this macro to change +% the name and label formatting, particularly when you wish to format +% the label and sub-label separately. +% +% \DescribeMacro{\ChemShortLabelStyle} Internal macro used to formats a +% label without name text. Users may redefine this macro to change the +% name and label formatting, particularly when you wish to format the +% label and sub-label separately. +% +% \DescribeMacro{\ChemMainCounterStyle} Internal macro that converts the +% counter used for main key label into a number or letter. The default +% implementation uses |\arabic| to generate a number. Users may redefine +% this macro to output letters instead of numbers. +% +% \DescribeMacro{\ChemSubCounterStyle} Converts the counter used for the +% sub-key label into a number or letter. The default implementation uses +% |\alph| to generate a letter. Users may redefine this macro to output +% numbers instead of letters. +% +% \section{Design brief} +% +% This section contains a description of what this package sets out to +% achieve. +% The package should be able to consistently label an entity throughout +% the document based on a user-defined key. The label can be either a +% consecutive number or a user-defined label. These labels can be +% combined with a sub-label, which can also be consecutive or +% user-defined. +% +% When sub-labels are used a user-supplied key and sub-key are +% required. Any entity associated with the key without a sub-key is +% considered to be a generic entity for any entities defined with the +% same key and a sub-key. +% +% \subsection{Limits} +% +% \begin{itemize} +% \item The package can provide consecutive labels or user-defined +% labels but not both. +% +% \item Unless user-defined labels are used, consecutive labels are +% numeric for labels and alphabetic for sub-labels. +% +% \item The package can provide only a single set of consecutive labels. +% +% \item The package can provide consecutive sub-labels or user-defined +% sub-labels but not both for each label. +% \end{itemize} +% +% \subsection{Actions} +% +% \begin{itemize} +% \item The first time the |\ChemCite| macros appear in the latex document +% with a given key is where the consecutive number label for the key +% is defined (unless user-defined label are being used). +% +% \item Using macros |\ChemCite*| provides the label without defining the +% consecutive number label. This allows the label to appear, for +% example in a table, abstract or figure, before the desired defining +% location of the label. +% +% \item The names of entities can be defined anywhere in the document +% and appear in a user-controlled manner. +% +% \item The basic macros typeset the entity name and label at the first +% defining reference position and only the label in other places. +% +% \item A range of advanced macros allow greater control over the +% display of the entity name and label. For example the user can +% output a label and sub-label but use the name of the generic entity. +% A chemistry example of this with ``ethyl acetate (1b)'' and its +% generic entity ``acetic acid ester (1)'' appearing as ``\dots{}gives +% the second acetic acid ester (1b)\dots{}''. +% +% \item The label will be typeset in a particular, user configurable, +% style. The label should be consistently formatted, even in +% math-mode. +% +% \item The label can be used transparently by other packages. For +% example it can be used with the \textsf{psfrag} package to inject +% the correct labels into figures at documentation preparation time +% rather than having to recreate new figures whenever the label +% numbering changes. +% +% \end{itemize} +% +% \section{Package options} +% +% The package has two options. Both options are intended to be used +% when debugging the package or its usage. Control of the style used +% when typesetting names and labels is optionally done manually by +% redefining the style control macros described elsewhere. +% +% \begin{description} +% \item[|draft|] Output structure/entity key as a superscript before +% any name and/or label output. This can be useful during document +% preparation. +% \item[|debug|] Output extra information in the processing log to do +% with the operation of the package and turn on |draft| mode. +% \end{description} +% +% \section{Implementation} +% +% The package creates a virtual mapping of keys to a name and a +% label. The key is stored as |Main!Sub| if the key has a sub-key. This +% mapping is stored into the \textsf{aux} file where it is read at the +% start of each document processing. If the mapping is altered during +% processing the user gets a warning to reprocess the document, similar +% to other automatically created indices. +% +% The package has several sets of macros. The public macros are used to +% define the key to name mapping and to lookup and output the names and +% labels based on the key during document processing. One set of +% internal macros defines the style used to display the name and +% labels. These macros can be redefined by the user. A second set of +% internal macros controls the definition and management of the map +% data. A third set controls logging information and extra output that +% might be used during testing. +% +% This uses a simple first cited first numbered algorithm to generate a +% unique sequential label for a set of compounds. It relies on a set of +% chemical definitions that can appear anywhere in the text and are +% stored in the ``aux'' file at program termination and read in at +% program start up. +% +% Note on programming style. All the functions are declared using LaTeX +% commands unless using TeX functions |edef|, |gdef| and |xdef| were +% required. The public functions have been defined using LaTeX2e's +% |DeclareRobustCommand*{}|. +% +% \StopEventually{} +% +% \subsection{Output Style Macros} +% +% \begin{macro}{\ChemLabelStyle} \marg{label} The default implementation +% formats the label in a sloping bold font. +% \begin{macrocode} +\DeclareRobustCommand*{\ChemLabelStyle}[1]{% + \textsl{\bfseries{}#1}} +% \end{macrocode} +% \end{macro} +% +% \begin{macro}{\ChemFullLabelStyle} +% \marg{full name} \marg{main label} \marg{sub-label} Formats the full +% entity name and label. The default implementation does not format +% the entity name, simply forwarding the argument as-is. The default +% implementation appends the sub-key label to the main label and uses +% the |\ChemLabelStyle| to format them together. +% \begin{macrocode} +\DeclareRobustCommand*{\ChemFullLabelStyle}[3]{% + \ifthenelse{\equal{}{#3}}{% + #1 (\ChemLabelStyle{#2})% + }{% + #1 (\ChemLabelStyle{#2#3})% + }% +}% +% \end{macrocode} +% \end{macro} +% +% \begin{macro}{\ChemShortLabelStyle} +% \marg{main label} \marg{sub-label} Formats the labels when they +% appear without the entity name. The default implementation appends +% the sub-key label to the main label and uses the |\ChemLabelStyle| +% to format them together. +% \begin{macrocode} +\DeclareRobustCommand*{\ChemShortLabelStyle}[2]{% + \ifthenelse{\equal{}{#2}}{% + \ChemLabelStyle{#1}% + }{% + \ChemLabelStyle{#1#2}% + }% +}% +% \end{macrocode} +% \end{macro} +% +% \begin{macro}{\ChemMainCounterStyle}\marg{counter} +% Converts the counter used for the main key label into a number or +% letter. The default implementation uses |\arabic| to generate a +% number. +% \begin{macrocode} +\DeclareRobustCommand*{\ChemMainCounterStyle}[1]{% + \arabic{#1}} +% \end{macrocode} +% \end{macro} +% +% \begin{macro}{\ChemSubCounterStyle}\marg{counter} +% Converts the counter used for the sub-key label into a number or +% letter. The default implementation uses |\alph| to generate a +% letter. +% \begin{macrocode} +\DeclareRobustCommand*{\ChemSubCounterStyle}[1]{% + \alph{#1}} +% \end{macrocode} +% \end{macro} +% +% \subsection{Macros for Debugging and Draft Output} +% +% Several macros are defined to implement the |draft| and |debug| +% package options. When these options are not used these macros fall +% back on default implementations that mostly do nothing. These macros +% are redefined when the options are used. +% +% \begin{macro}{\CN@DEBUG} +% Internal macro used to suppress debugging messages when not +% debugging. This is redefined if the |debug| package option is used +% to output debugging messages in the processing log. +% \begin{macrocode} +\makeatletter +\gdef\CN@DEBUG #1#2{} +% \end{macrocode} +% \end{macro} +% \begin{macro}{\CN@WARN} +% Internal macro used to output errors and warnings as information +% messages when not debugging. This is redefined if the |debug| option +% is used to promote these messages to warning messages in the +% processing log. +% \begin{macrocode} +\gdef\CN@WARN #1#2{\PackageInfo{#1}{#2}} +% \end{macrocode} +% \end{macro} +% \begin{macro}{\CN@DRAFT} +% Internal macro used to suppress draft only output when not in draft +% mode. This is redefined if the |debug| or |draft| option is used to +% add superscript text in the output document. +% \begin{macrocode} +\gdef\CN@DRAFT #1{} +% \end{macrocode} +% \end{macro} +% +% \subsection{Options for Debugging and Draft Output} +% +% The package has several options to help with using the package. +% +% \begin{itemize} +% \item The \textsf{debug} option generates more error and warning +% messages as well as outputting draft data. It does this by redefining +% the |\CN@DEBUG|, |\CN@WARN| and |\CN@DRAFT| macros. +% \begin{macrocode} +\DeclareOption{debug}{% + \gdef\CN@DEBUG #1#2{\PackageInfo{#1}{#2}}% + \gdef\CN@WARN #1#2{\PackageWarning{#1}{#2}}% + \gdef\CN@DRAFT #1{$^{[#1]}$}% +} +% \end{macrocode} +% \item The \textsf{draft} option outputs some draft data.

This is a guard value for erroneous usage. +% \begin{macrocode} +\expandafter\def\csname CN@@label\endcsname{999} +% \end{macrocode} +% \item |\CN@@name| is a dummy name used when no name is found for a +% particular key. This is a guard value for erroneous usage. +% \begin{macrocode} +\expandafter\def\csname CN@@name\endcsname{X} +% \end{macrocode} +% \item |\CN@@sublabel| is a dummy sub-label used when no label is found +% for a particular key/sub-key. This is a guard value for erroneous +% usage. +% \begin{macrocode} +\expandafter\def\csname CN@@sublabel\endcsname{X} +% \end{macrocode} +% \item |CN@KeyFound| is a boolean to signal whether the key was found +% in the key list. Failure to be found indicates that this is the first +% time this key was cited. +% \begin{macrocode} +\newboolean{CN@KeyFound} +% \end{macrocode} +% \item |CN@ScanList| is a boolean to signal whether the key was found +% in the last loop of the map scan. +% \begin{macrocode} +\newboolean{CN@ScanList} +% \end{macrocode} +% \item |CN@Star| is a boolean that signals that a macro was called +% using the star form of the command.
