Well -- here we go and you might find it useful, too, I -hope. - -Both the macros and their functionality have changed over time and quite a lot -have been added. Many things have been unified and what's probably most -important: many possibilities to customize have been added, too. - -Probably every chemist using \LaTeXe\ is aware of the great \pkg{mhchem} -package by \hensel. There have always been some difficulties intertwining it -with \chemmacros, though. Also, some other minor points in \pkg{mhchem} -always bothered me, but they hardly seemed enough for a new package. They -weren't even enough for a feature request to the \pkg{mhchem} author. The -challenge and the fun of creating a new package and the wish for a highly -customizable alternative led to \chemformula\ after all. \chemformula{} used -to part of \chemmacros{} for quite a while but now is an independent package. - -As a chemist you are probably aware of the fact that the \acl{UN} have -developed the \ac{ghs} as a global replacement for the various different -systems in different countries. While it has not been implemented by all -countries yet~\cite{unece:ghsystem_implementation}, it is only a matter of -time. - -The package \ghsystem\ enables you to typeset all the hazard and precautionary -statements and pictograms in a very easy way. The statements are taken from -\acs{eu} regulation 1272/2008~\cite{eu:ghsystem_regulation}. \ghsystem{} used -to be a part of \chemmacros{} for quite a while but now is an independent -package. - -There are four points I hope I have achieved with this package: +\chemmacros\ loads the packages \pkg{expl3}~\cite{bnd:l3kernel} and +\pkg{xparse}~\cite{bnd:l3packages}. Depending on your usage other packages +will be loaded. They are mentioned when the corresponding module using the +package is described. + +\section{Motivation and Background}\label{sec:motiv-backgr} +This package grew from a small collection of personal helper macros back +in~2010 into a rather big package supporting various different chemical +typesetting tasks. I hope I have achieved the following points with this +package: \begin{itemize} - \item intuitive usage as far as the syntax of the commands is concerned - \item the commands shall not only make typesetting easier and faster but also - the document source more readable with respect to semantics + \item Intuitive usage as far as the syntax of the commands is concerned. + \item A comprehensive set of macros! If there are any needs you might have + with respect to typesetting of chemistry which is not supported by this + package\footnote{Not including needs already solved by other packages such + as \pkg{chemnum} or \pkg{chemfig}.} then let me know so \chemmacros\ can + be extended. + \item The commands shall not only make typesetting easier and faster but + also the document source more readable with respect to semantics (\code{\cs{ortho}-dichlorobenzene} is easier to read and understand than - \code{\cs*{textit}\Marg{o}-dichlorobenzene}) - \item as much customizability as I could think of so every user can adapt the - commands to his or her own wishes - \item default settings compliant with the recommendations of the \acf{iupac}. -\end{itemize} -Especially the last point needed some pushing from users to get things right -in many places. If you find anything not compliant with \ac{iupac} -recommendations\footnote{This does not concern the \cs{ox} command. The - \ac{iupac} version is \cs{ox}\sarg.} I would welcome an email very much! - -\section{News} -\subsection{Version~4.0} -With version~4.0 some changes have been made: -\begin{itemize} - \item first of all the packages \chemformula\ and \ghsystem\ do not load - \chemmacros\ any more which means they can be used independently. - \item the option \option{bpchem} has been dropped. - \item the commands \cs{mch} and \cs{pch} now match \chemformula's - charges. - \item the option \option{method} has been dropped. - \item the option \option{append} has deprecated. - \item the option \option{greek} has been extended to support other uppercase - greek letters, for example those provided by \pkg{kpfonts}. This is - handled internally by the new package in the family: \chemgreek. This - package is not really a package for usage at a user-level but could in - principle be used to extend the \option{greek} option. - \item language support is now done with the help of the \pkg{translations}. - This means that with version~4.0 the document language is recognized - automatically. - \item the status of the commands \cs{Lfi} and \cs{Dfi} has been changed - from \emph{deprecated} to \emph{dropped}. - \item various other changes like bug fixes and improvements on the - typographical appearance of \chemformula's inline formulae with \cs{ch}. + \code{\cs*{textit}\Marg{o}-dichlorobenzene}); the first variant in my + opinion also is more in the spirit of \LaTeXe. + \item As much customizability as I could think of so every user can adapt + the commands to his or her own wishes. Every now an then users have + wishes which can't be solved with the available options. Almost always + I'll add options then. If you find something please contact me, see + section~\vref{sec:sugg-bug-reports}. + \item Default settings that are compliant with the recommendations of the + \acf{iupac}. \end{itemize} +Especially the last point in the past needed some pushing from users to get +things right in many places. If you find anything not compliant with +\ac{iupac} recommendations please contact me, see +section~\vref{sec:sugg-bug-reports}. Don't forget to add references for the +corresponding \ac{iupac} recommendation. + +\section{The Structure of \chemmacros}\label{sec:structure-chemmacros} +\subsection{General Structure} +Since version~5.0 the \chemmacros\ package has a strictly modular +structure\sinceversion{5.0}. On the one hand this eases maintenance but it +will also allow for easy and quick extension in the future. In a way it is a +logical consequence from \chemmacros' history: since version~2.0, \ie, since +the fall of~2011 \chemmacros\ already had modular options. + +The different modules of \chemmacros\ are divided into two groups: +\begin{enumerate} + \item Internal modules which provide underlying functionality or basic + functionality which is not of direct interest from a user perspective but + might be if you plan to write a module yourself (see + section~\ref{sec:own-modules} for details). + \item User modules which provide all the stuff for typesetting. +\end{enumerate} +Both groups each are subdivided into two groups: preloaded modules and modules +which have to be loaded by the programmer (internal modules) or by the +document author (user modules). Those modules are described in +parts~\ref{part:preloaded-modules} (preloaded modules) +and~\ref{part:additional-modules} (additional modules) of this manual. + +The above means that not all functionality is available per default. If you +want to load \emph{all} modules no matter what then you can say: +\begin{sourcecode} + \usechemmodule{all} +\end{sourcecode} +or +\begin{sourcecode} + \chemsetup{modules=all} +\end{sourcecode} +which will load all modules which are part of \chemmacros\ (also see +section~\vref{sec:all-module}). Own modules (see +section~\vref{sec:own-modules}) are \emph{not} loaded through this, though, +and still have to be loaded additionally. + +In part~\vref{part:preloaded-modules} the preloaded modules are described, +first the user modules then the internal ones, in +part~\vref{part:additional-modules} the other available modules are described, +again the user modules first. In each section the modules are described in +an alphabetical order. + +\subsection{Using \chemmacros' Options}\label{sec:using-chemm-opti} +Prior to v5.0 \chemmacros\ had quite a number of package options. +\chemmacros\ v5.0 or higher has none! All of \chemmacros's options are set +using the command +\begin{commands} + \command{chemsetup}[\oarg{module}\marg{option list}] + \chemmacros' setup command. +\end{commands} -\subsection{Version~4.2} +When an option is described then in the left margin the module the option +belongs to is denoted. This looks something like this: +\begin{options} + \keyval{option}{value}\Module{module}\Default + Description of \option{option}. The module is printed in the left margin. + The default value to the right is the setting the option has when + \chemmacros\ is loaded. This can be an explicit setting but the option + can also be empty. + \keychoice{choice-option}{list,of,\default{choices}}\Module{module}\Default{list} + Description of \option{choice-option}. A choice option can only be used + with a predefined list of values. If one of the values is underlined it + means that the option can be used without value in which case the + underlined value is chosen. If no value is underlined then a value + \emph{has} to be given by the user. + \keybool{boolean-option}\Module{module}\Default{true} + Description of \option{boolean-option}. A boolean option is a choice + option with exactly the two values \code{true} and \code{false}. If the + option is called without value then the underlined value is chosen (which + is always \code{true} for a boolean option). +\end{options} +An option or list of options belonging to a module \chemmodule{module} can be +set in two ways: +\begin{sourcecode} + % first possibility: + \chemsetup[module]{ + option1 = value , + option2 = value + } + % second possibility: + \chemsetup{ + module/option1 = value , + module/option2 = value + } +\end{sourcecode} +The second way allows to set options belonging to different modules with one +call of \cs{chemsetup}. + +\subsection{Support Package \chemformula} +\chemformula\ provides means of typesetting chemical formulas and reactions. +You will see its macros \cs{ch} and \cs{chcpd} every now and then in this +manual. When using \chemmacros\ you can consider the \chemformula\ +package~\cite{pkg:chemformula} to be loaded as \chemmacros\ makes use of it in +various places. \chemmacros\ and \chemformula\ are tightly intertwined. In +fact: \emph{when using \chemmacros\ you should prefer \chemformula\ over + \pkg{mhchem} (which provides very similar functionality) for having + consistent typesetting}. + +A historical note: \chemformula\ started as a part of \chemmacros\ in +January~2012. Since July~2013 it is a completely independent package -- from +\chemformula's point of view. It is maintained independently and has a manual +of its own. + +\subsection{Upgrading from version $<5.0$} +People upgrading from versions $<5.0$ will find that almost everything they +know from earlier versions is the same in versions $\geq5.0$. But there are +important and \emph{breaking} differences: \begin{itemize} - \item Changed particles with electron pairs such as \cs{ba} to use - \chemformula's new macro \cs{chlewis} for the Lewis electrons. - \item Changed the implicit \cs*{Delta} in the thermodynamic state variables - into \cs*{ChemDelta} to ensure that an upright symbol is used. - \item Change in the syntax of \cs{DeclareChemState} and - \cs{RenewChemState}. The old syntax is still supported but discouraged. + \item \chemmacros\ has no package options any more, all options are set via + \cs{chemsetup}, also see section~\vref{sec:using-chemm-opti}. + \item Not all of the features are available per default any more, for some + the corresponding module has to be loaded explicitly, see + section~\ref{sec:general-options}. If suddenly some commands or + environments seem to be undefined this is the most likely reason. + \item Some option modules have been renamed (\eg, \module*{iupac} is now + \module{nomenclature}). If you experience strange errors when you upgrade + your document this is the most likely source. + \item The command family \cs*{NewChem\ldots}, \cs*{RenewChem\ldots} and + \cs*{DeclareChem\ldots} has a new member \cs*{ProvideChem\ldots}. + \item In \cs{iupac} the macro \cs*{-} no longer gives a dash with breaking + point. Instead \sym*{-} can be used directly\footnote{\cs*{-} will be + provided a bit longer for easing the upgrade step but will be dropped + eventually.}. + \item The macro \cs{ox} has another default behaviour (\keyis{pos}{super}) + and the starred version has another effect (\keyis{pos}{top}) than the + same macro in earlier versions. Now the default behaviour follows + \acs{iupac} recommendations. A second change is that the atom is now + treated as a \chemformula\ formula. + \item The syntax of \cs{NewChemReaction} and friends is now different from + what it used to be. If you have defined your own reaction environments + you need to adapt! + \item \chemmacros\ offers a macro \cs{state} which is similar to but + different from the earlier macro \cs*{State}. \cs*{State} is deprecated. + There are also differences in the syntax of \cs{enthalpy} \vs\ the earlier + \cs*{Enthalpy}, \cs{entropy} \vs\ \cs*{Entropy} and \cs{gibbs} \vs\ + \cs*{Gibbs}.

The one-letter commands still exist for - backward compatibility (and to some users no doubt also for convenience). - They are no longer recommended though. One-letter commands seldomly have - meaningful names and often they've also been defined by other packages. - This means they make collaboration more difficult than it needs to be and - are a source for package conflicts. \chemmacros\ used to solved the - latter problem by only providing them inside the argument of - \cs{iupac}\label{desc:one-letter-commands}. The one exception - \chemmacros\ makes is the command \cs{p} (for things like \pH) which is - and will remain an official command. - \item The environment \env{experimental} has got a number of new options, - see section~\ref{sec:experimental-customization}. - \item The commands \cs*{DeclareChem\meta{...}} now don't give an error any - more if the command already exists. This is more consistent with \LaTeX's - \cs*{DeclareRobustCommand}. For all those commands a version - \cs*{NewChem\meta{...}} is introduced that \emph{does} give an error if - the new command is already defined. - \item The package option \option{strict} has been deprecated. - \item The package option \option{cmversion} has been deprecated. - \item The command \cs{mhName} has been dropped. -\end{itemize} +\subsection{Compatibility Mode} -\subsection{Version 4.4} -\begin{itemize} - \item New \module{nmr} option \option{atom-number-cs}. - \item New \module{nmr} option \option{coupling-pos-cs}. -\end{itemize} +\subsubsection{For Users} +It is actually not true that \chemmacros' has no package options any more.

For the following explanations it will be +helpful if you know about said package and how it works first. This module is +a support module that defines the macro \begin{commands} - \command{newman}[\oarg{options}\darg{angle}% - \Marg{\meta{1},\meta{2},\meta{3},\meta{4},\meta{5},\meta{6}}] - Create Newman projections. This command uses \TikZ\ internally. - \meta{angle} rotates the back atoms counter clockwise with respect to the - front atoms and is an optional argument. \meta{1} to \meta{6} are the - positions, the first three are the front atoms, the last three the back - atoms. + \command{chemfrac}[\oarg{type}\marg{numerator}\marg{denominator}] + \meta{type} can either be \code{text} or \code{superscript}. \end{commands} +This macro calls a certain instance of the \pkg{xfrac} \code{text} template, +depending on the option \meta{type} and the current font family. If used +\cs{chemfrac} looks if an instance +\begin{center} + \code{chemmacros-frac-\cs*{f@family}-\meta{type}} +\end{center} +exists. If yes this instance is used, if no the instance +\code{chemmacros-frac-default-\meta{type}} is used. The \code{default} +instances are the same as the ones for \code{cmr}. -\begin{example} - \newman{} \newman(170){} - \newman{1,2,3,4,5,6} \newman{1,2,3} \newman{,,,4,5,6} -\end{example} +\begin{table} + \centering + \newcommand*\showfrac[1]{% + \code{#1} & + \fontfamily{#1}\selectfont + \chemfrac[text]{2}{3} & + \fontfamily{#1}\selectfont + \chemfrac[superscript]{2}{3}% + } + \caption{Predefined \chemmodule{xfrac} \code{text} instances.} + \label{tab:xfrac} + \begin{tabular}{llcc} + \toprule + \bfseries font family & \bfseries text & \bfseries superscript \\ + \midrule + \showfrac{cmr} \\ + \showfrac{lmr} \\ + \showfrac{LinuxLibertineT-TLF} \\ + \showfrac{LinuxLibertineT-TOsF} \\ + \bottomrule + \end{tabular} +\end{table} -Several options allow customization: -\begin{options} - \keyval{angle}{angle}\Module{newman}\Default{0} - Default angle. - \keyval{scale}{factor}\Module{newman}\Default{1} - Scale the whole projection by factor \meta{factor}. - \keyval{ring}{tikz}\Module{newman}\Default - Customize the ring with \TikZ\ keys. - \keyval{atoms}{tikz}\Module{newman}\Default - Customize the nodes within which the atoms are set with \TikZ\ keys. - \keyval{back-atoms}{tikz}\Module{newman}\Default - Explicitly customize the nodes of the back atoms with \TikZ\ keys. -\end{options} +The \chemmodule{xfrac} module defines instances some font families, they are +listed and demonstrated in table~\vref{tab:xfrac}. The \code{superscript} +type fractions \emph{look} larger than the \code{text} types. The reason is +that the \code{superscript} types are typically used with a smaller font size. +Let's take a look at an example where both instances are used: +\begin{example}[side-by-side] + \chemsetup[redox]{pos=top} + \code{superscript}: + \ch{"\ox{1/3,I}" {}3+} -\begin{example} - \chemsetup[newman]{angle=45} \newman{} - \newman[scale=.75,ring={draw=blue,fill=blue!20}]{} -\end{example} + \chemsetup[redox]{pos=side} + \code{text}: \ox{1/3,I3+} -\begin{example} - \chemsetup[newman]{atoms={draw=red,fill=red!20,inner sep=2pt,rounded corners}} - \newman{1,2,3,4,5,6} -\end{example} + \huge + \chemsetup[redox]{pos=top} + \code{superscript}: + \ch{"\ox{1/3,I}" {}3+} -\begin{example} - \chemsetup[newman]{ - atoms = {draw=red,fill=red!20,inner sep=2pt,rounded corners}, - back-atoms = {draw=blue,fill=blue!20,inner sep=2pt,rounded corners} - } - \newman{1,2,3,4,5,6} \newman(170){1,2,3,4,5,6} + \chemsetup[redox]{pos=side} + \code{text}: \ox{1/3,I3+} \end{example} -\section{s, p, and Hybrid Orbitals}\label{sec:orbitale} - -\chemmacros\ provides the following command to create orbitals: -\begin{commands} - \command{orbital}[\oarg{options}\marg{type}] - Draw an orbital shape of type \meta{type}. This command uses \TikZ\ - internally. -\end{commands} +If you define instances for other families please feel free to submit them to +me (see section~\vref{sec:submitting-module}) so they can be added to the +\chemmodule{xfrac} module. -There are the following types available for \meta{type}: -\begin{itemize} - \item[] - \code{s} \quad - \code{p} \quad - \code{sp} \quad - \code{sp2} \quad - \code{sp3} -\end{itemize} +\appendix +\part{Appendix} +\section{Own Modules}\label{sec:own-modules} +\subsection{How To} -\begin{example} - \orbital{s} \orbital{p} \orbital{sp} \orbital{sp2} \orbital{sp3} -\end{example} +If you have additional functionality which you think might be useful as a +\chemmacros\ module then you can easily write one yourself.
