+cooking-units
+=============
+
+Overview
+--------
+
+While writing a cookery book, units and their format can be quite
+troublesome. This contains not only the question of how to print those
+units, but also the question of the conversion of units. A cookery book
+doesn't contain only SI units, it contains a much more colorful range
+of units (kg, dag, g, oz, ... for example) and this may cause some
+confusion if too many different units are used, but if you just write a
+cookery book for fun you don't think about this case ... until someone
+(my mother in my case) tells you that it's too confusing.
+
+This package solves both problems: It formats your input and
+you have the option to convert the units globally or locally using a key-value
+system.
+
+Please note that this package is not intended to be used to
+print units (and numbers) physically correct. It should be used for
+more light-hearted stuff (like a cookery book for example).

+% \section{Introduction}
+%
+%
+% While writing on a cookery book I used -- for reasons whatsoever --
+% three different units for weight: kilogram (kg), gram (g) and
+% decagram (dag). Later my mother told me that she doesn't like it if a
+% cookery book uses more than two different units (for weight in this case). Happily
+% I hardly used Decagram and therefore didn't have many problems
+% changing the units. But, well \dots\ I am using \LaTeX\ and changing
+% those units by hand seemed not very \LaTeX\-like, so I started
+% writing some code to convert units. I expanded the code, rewrote it
+% in \LaTeX3 (which is much more pleasant than \LaTeXe) and here it
+% is.
+%
+% \section{Important note}
+%
+% This package uses the \pkg{translator} package to be able to switch
+% between different languages (german, english and french by now).
+% To do that \pkg{translator} has to know
+% which languages are used. The (I think) easiest way is to specify
+% used languages using the optional argument of the documentclass (you
+% can do this for both \pkg{babel} and \pkg{polyglossia}\footnote{I
+% know that \pkg{polyglossia} doesn't support the \pkg{babel}-way of
+% setting the language by optional argument, but it doesn't harm.}):
+%
+% \begin{lstlisting}
+% \documentclass[english,french,ngerman]{class}
+% \usepackage[main=english]{babel}
+% \usepackage{cooking-units}
+% ...
+% \end{lstlisting}
+%
+% or if you are using \pkg{polyglossia}
+%
+% \begin{lstlisting}
+% \documentclass[french,ngerman,english]{class}
+%
+% \usepackage{polyglossia}
+% \setmainlanguage{english}
+% \setotherlanguages{german,french}
+%
+% \usepackage{cooking-units}
+% ...
+% \end{lstlisting}
+%
+% At least I hope that this works, dealing with languages is a pain in
+% the ass\footnote{If you excuse me being blunt about this}.
+%
+% \section {The Commands}
+%
+% This package offers the following commands for unit printing (and converting):
+%
+% \begin{itemize}
+% \item \mycs{cunum} \oarg{options}\marg{amount}\oarg{space}\marg{unit-key}
+% \item \mycs{cutext}\oarg{options}\marg{amount}\marg{unit-key}
+% \item \mycs{Cutext}\oarg{options}\marg{amount}\marg{unit-key}
+% \item \mycs{cufrac}\marg{input}
+% \end{itemize}
+%
+% Numbers and units are printed using \mycs{cunum}. The numerical part
+% can interpret \verb|_| and \texttt{/} as (mixed) fractions and
+% \verb|--| as a separator for ranges; to convert units use the option
+% \texttt{\meta{old-unit}=\meta{new-unit}}\footnote{New keys can be
+% added and defined, see \vref{sec:pred-units} and
+% \vref{sec:def-units} for further information.}. It furthermore allows the
+% sign \texttt{?} to be used as a placeholder for not known amounts
+% and raises a warning
+% to remind that this amount needs a checkup\footnote{You can
+% customize this behavior, see \vref{sec:options}}. \oarg{space} adds
+% a space between the number and the unit using \lstinline|\phantom|.
+%
+% For a list of predefined units have a look at \vref{tab:def-units}.
+%
+%
+% \begin{cuexamplecode}
+% \cunum{1}{kg} \\
+% \cunum{2.3}{kg} \\
+% \cunum{2,3}{kg} \\
+% \cunum{2--3}{kg} \\
+% \cunum{2.5--3.5}{kg} \\
+% \cunum[kg=g]{2.5--3.5}{kg} \\
+% \cunum[C=F]{200}{C} \\
+% \cunum[C=F]{180--200}{C} \\
+% \cunum{1/2}{m} \\
+% \cunum{1_1/2}{m} \\
+% \cunum[m=cm]{1_1/2}{m} \\
+% \cunum{?}{l} \\
+% \cunum{50}{dag} \\
+% \cunum{5}[0]{dag} \\
+% \cunum{1.1234}{m}
+% \end{cuexamplecode}
+%
+% Decimal numbers are automatically rounded to 2 digits after the
+% colon, temperatures (\texttt{C}, \texttt{F}, \texttt{K} and
+% \texttt{Re}) are automatically rounded to integers.\footnote{You can
+% -- of course -- change this behavior, see \vref{sec:options}.}
+%
+% \lstinline|\cutext| and \lstinline|\Cutext| print the number and the
+% written name of the unit. Furthermore, if the package option
+% \opt{use-numerals} is used, integers below a specific integer (by
+% default 13; see \opt{use-numerals-below}) are also written out with
+% \lstinline|\Cutext| capitalizing the first letter (using package \pkg{fmtcount}).
+% Conversion between
+% units is not supported. Without \opt{use-numerals}:
+%
+% \begin{cuexamplecode}
+% \cutext{1}{l} \\
+% \Cutext{1}{l} \\
+% \cutext{12}{l} \\
+% \Cutext{13}{l}
+% \end{cuexamplecode}
+% and using package option \opt{use-numerals=true}
+% \cusetup{use-numerals-below=13}
+% \begin{cuexamplecode}
+% \cutext{1}{l} \\
+% \Cutext{1}{l} \\
+% \cutext{12}{l} \\
+% \Cutext{13}{l}
+%^^A \cutext{23}{kg} \\
+%^^A \Cutext{23}{kg}\\
+%^^A \cutext{1}{l}\\
+%^^A \Cutext{2}{l}\\
+%^^A \cutext{1}{C} \\
+%^^A \cutext{180}{C} \\
+%^^A \Cutext{1}{C} \\
+%^^A \Cutext{180}{C} \\
+%^^A \Cutext{1.4}{C} \\
+% \end{cuexamplecode}
+% \cusetup{use-numerals-below=0}
+%
+%
+% \lstinline|\cufrac| can be used to print fractions. Like in \lstinline|\cunum|
+% \texttt{\_} and \texttt{/} are used to imply a (mixed) fraction:
+%
+% \begin{cuexamplecode}
+% \cufrac{3} \\
+% \cufrac{2/3} \\
+% \cufrac{1_2/3}
+% \end{cuexamplecode}
+%
+%
+% \section{Predefined units \& some notes}
+% \label{sec:pred-units}
+%
+% In \vref{tab:def-units} you can find all predefined units.
+%
+% I did not include a separate key for \enquote{Prise} (pinch), but you can use
+% \texttt{Msp} (Messerspitze) and modify it to fit your
+% purpose\footnote{See \vref{sec:language}.}.
+% In other languages the nearest equivalent of \enquote{Messerspitze} is
+% \enquote{pinch} which I used.
+%
+%^^A Please note that this package uses \texttt{translator} for defining translations,
+%^^A so you may put
+%

+%
+% \section{Defining units}
+% \label{sec:def-units}
+%
+% New units can be defined using \lstinline|\newcookingunit|:
+%
+% \begin{function}{\newcookingunit}
+% \begin{syntax}
+% \lstinline|\newcookingunit|\oarg{symbol}\marg{new-unit-key}
+% \end{syntax}
+% This command defines the new unit \meta{new-unit-key}. If the
+% key is not the same as the printed symbol use \oarg{symbol}.
+%
+% Some examples (note: the definition of the printed degree Celsius is
+% directly copied \& pasted from [a maybe older version of] \pkg{siunitx}):
+%
+% \begin{center}
+% \begin{tabular}{ll}
+% \lstinline|\newcookingunit{kg}| \\
+% \lstinline|\newcookingunit{g}| \\
+% \lstinline|\newcookingunit[Msp.] {Msp}| \\
+% \lstinline|\newcookingunit[\ensuremath{{}^{\circ}}\kern-\scriptspace C] {C} |
+% \end{tabular}
+% \end{center}
+%
+% \end{function}
+%
+%
+% \section{Defining options}
+% \label{sec:defining-opt}
+%
+% Options (to change units) can be newly defined or added to already existing keys
+% using
+% \begin{itemize}
+% \item \lstinline|\cudefinekeys|
+% \item \lstinline|\cudefinesinglekey|
+% \item \lstinline|\cuaddkeys|
+% \item \lstinline|\cuaddsinglekeys|
+% \item \lstinline|\cuaddtokeys|
+% \end{itemize}
+%
+%
+%
+% \begin{function}{\cudefinekeys,\cudefinesinglekey}
+% \begin{syntax}
+% \mycs{cudefinekeys}\marg{unit-key-1}
+% \ \ \{
+% \ \ \ \ \marg{unit-key-2} \marg{1 unit-key-1 are \dots\ unit-key-2}
+% \ \ \ \ \marg{unit-key-3} \marg{1 unit-key-1 are \dots\ unit-key-3}
+% \ \ \ \ \marg{unit-key-4} \marg{1 unit-key-1 are \dots\ unit-key-4}
+% \ \ \ \ \dots
+% \ \ \}
+%
+% \mycs{cudefinesinglekey}\marg{unit-key-1}
+% \ \ \{
+% \ \ \ \ \marg{unit-key-2} \marg{1 unit-key-2 are \dots\ unit-key-1}
+% \ \ \ \ \marg{unit-key-3} \marg{1 unit-key-3 are \dots\ unit-key-1}
+% \ \ \ \ \dots
+% \ \ \}
+% \end{syntax}
+%
+% If you define new units (see \vref{sec:def-units}) and cannot add
+% them to already existing keys you can use \lstinline|\cudefinekeys| bzw.
+% \lstinline|\cudefinesinglekey| to define new keys.
+%
+% \lstinline|\cudefinekeys| takes the \marg{unit-key-1} as a \enquote{basis},
+% defines a key with the name \meta{unit-key-1} and adds the values
+% \meta{unit-key-1}, \meta{unit-key-2}, \meta{unit-key-3}, etc. Furthermore
+% this command also defines the keys \meta{unit-key-2}, \meta{unit-key-3}, etc.
+% with the same values as \meta{unit-key-1}. Please note that \meta{\dots} has to
+% be a number. ^^A Those keys are linked to each other.
+%
+% Sometimes it is not that easy and the conversion of one unit into another
+% needs are more complicated formula (see for example temperatures).
+% If that is the case use \lstinline|\cudefinesinglekey|. As the name says it
+% defines \emph{only} the key \meta{unit-key-1} with the values \meta{unit-key-1},
+% \meta{unit-key-2}, etc. The advantage of this command is that now
+% \meta{\dots} can be a formula and the numerical input can be placed explicitly
+% using \texttt{\#1}.
+%
+%
+% \end{function}
+%
+% \begin{cuexample}
+%
+% This example defines following keys with their respective value:

+% \section{Language support}
+% \label{sec:language}
+%
+% The unit names and symbols depend on the language. To change the
+% name depending on the language you can use \lstinline|\cudefinename|
+% and to only change symbols use \lstinline|\cudefinesymbol|.
+%
+% \begin{function}{decimal-mark, one(m),one(f),one(n)}
+% Those are special keys (as they cannot be used as units). Not only
+% are printed units language depending, but as is the decimal
+% mark (\enquote{.} or \enquote{,}). To set the decimal mark use
+% \opt{decimal-mark} (see examples below).
+%
+% Furthermore if you are using the package-option \opt{use-numerals} you may
+% also use the keys \opt{one(m)}, \opt{one(f)} and \opt{one(n)}. If
+% you use this option, integers below a certain value (see option
+% \opt{use-numerals-below}) are written-out. The only problem is
+% the written-out \enquote{1} mostly depends on the gender of the
+% following word (e.g. \enquote{ein Baum} (m),
+% \enquote{eine Pflanze} (f) and \enquote{ein Auto} (n)). To set the
+% written-out 1 to be correct with the gender of the used unit, use
+% this key (see also examples below)

+% \ \ \ \ \dots
+% \ \ \}
+% \end{syntax}
+%
+% This command defines the names (and optionally the symbol) of the
+% commands printed in \lstinline|\cutext| and \lstinline|\Cutext|
+% (and \lstinline|\cunum| regarding the symbol) for the specific
+% \meta{Language}. For details regarding \meta{language} see the
+% \pkg{translator}-documentation.
+%
+% If the plural form of the name differs from the singular form use
+% \oarg{plural} to specify the plural form, if no \oarg{plural} is
+% given the plural will be set equal to its singular. The singular
+% is only used if the number in \lstinline|\cutext| and
+% \lstinline|\Cutext| is equal to 1.
+%
+% \meta{gender} can be \texttt{m} (maskulin), \texttt{f} (feminin) or
+% \texttt{n} (neutrum). If not given \texttt{m} is used as default.

+% \section{Bugs \& Feedback}
+%
+% Bug reports are always welcome. If you are sending a bug report
+% please include a minimal working example showing the bug and a short
+% description. Furthermore please add \enquote{cooking-units}
+% to the e-mail header. GMX has the habit of putting e-mails into the
+% spam account and adding \enquote{cooking-units} to the header makes
+% it easier to recognize those e-mails.
+%
+% Feedback and requests are most welcome. Please also add (if possible) an example of the
+% desired output into the minimal example (and also add \enquote{cooking-units}
+% to the header).
+%
+% Furthermore, as you can see I am not able to speak too many languages (german and
+% english to be precise; I managed to add french with the help of the internet,
+% which is not optimal) so if you are able to speak a language not yet implemented
+% and would like to help you can send me a list of the translations of the units given in
+% \vref{tab:def-units}. I would need
+% \begin{itemize}
+% \item their singular (and plural) form,
+% \item the gender,
+% \item the printed symbol (if different),
+% \item \texttt{decimal-mark} and \texttt{one(m)}, \texttt{one(f)}, \texttt{one(n)}
+% \end{itemize}
+%
+% Oh yeah, if someone has a better idea of how to deal with languages I am happy to know.

+% Yeah \dots\ \lstinline|\l_tmpa_clist| stores all the used unit-keys, while
+% the property list saves the relation to each other. This cycle is repeated until an
+% recursion tail is found. If you define a new key, \verb|\l_tmpa_fp| is set to
+% 1 and changed later if a new key is added.
+% \begin{macrocode}

+% \end{macro}
+%
+% \begin{macro}{ \@@_cukeys_create_key_prop:n }
+% All linked unit-keys are stored within \lstinline|\l_tmpa_clist| and are mapped
+% one after another. At first a property list is created (or cleared), this property list
+% stores the units linked to this unit, saves the created property list which contains the
+% numerical relation of each unit. \lstinline|Erstes Ding| (firsth thing) stores
+% the first unit used for defining the keys, it is needed later for adding keys.
+%
+% For each unit the other units are added in the cleared or newly created property list
+% as keys with their value being the correct numerical relation. For example:
+%
+% \begin{align*}
+% \SI{1}{\kg}&= \SI{1}{\kg} \\
+% \SI{1}{\kg}&= \SI{100}{\deka\gram} \\
+% \SI{1}{\kg}&= \SI{1000}{\g} \\
+% \SI{1}{\kg}&= \SI{35.27399}{oz} \\
+% \end{align*}
+%
+% Therefore the property list for \lstinline|kg| contains the keys and values:
+% \texttt{kg}=\texttt{1}
+% \texttt{dag}=\texttt{100}, \texttt{g}=\texttt{1000} and \texttt{oz}= \texttt{35.27399}.
+%
+% For the next unit (\texttt{dag} in this case) a new property list is created, relation above
+% stored inside etc. The condition now is that \texttt{dag}=\texttt{1}, therefore every number
+% is divided the the number \texttt{100}:
+%
+% \begin{align*}
+% \SI{1}{\deka\gram}&= \SI{0.01}{\kg} \\
+% \SI{1}{\deka\gram}&= \SI{1}{\deka\gram} \\
+% \SI{1}{\deka\gram}&= \SI{10}{\g} \\
+% \SI{1}{\deka\gram}&= \SI{0.3527399}{\oz} \\
+% \end{align*}
+%
+% Same for \texttt{g}:
+%
+% \begin{align*}
+% \SI{1}{\g}&= \SI{0.001}{\kg} \\
+% \SI{1}{\g}&= \SI{0.1}{\deka\gram} \\
+% \SI{1}{\g}&= \SI{1}{\g} \\
+% \SI{1}{\g}&= \SI{0.03527399}{oz} \\
+% \end{align*}
+%
+% and \texttt{oz}
+%
+% \begin{align*}
+% \SI{1}{oz}&= \SI{0.0283495}{\kg} \\
+% \SI{1}{oz}&= \SI{2.83495}{\deka\gram} \\
+% \SI{1}{oz}&= \SI{28.3495}{\g} \\
+% \SI{1}{oz}&= \SI{1}{oz} \\
