-The keys3 package --- Key management for LaTeX3

-The keys3 package is an experimental implementation of key
-management for LaTeX3. The entire package is written in
-expl3 code rather than in traditional TeX/LaTeX. The key
-model used by keys3 is based on the idea that keys are created
-by setting key properties:
-
- \keys_define:nn { module } {
- key .code:n = Hello #1,
- key .value_required:
- }
-
-The keys3 package is intended as a method for testing how key
-management might be implemented in LaTeX3. Both the methods
-used inside the package and the interface provided are intended
-to be discussed. Feedback is welcomed either by e-mail
-(joseph.wright@morningstar2.co.uk) or to the LaTeX-L mailing
-list.
-
-The experimental nature of keys3 means that it should not be
-used in production documents. However, programmers testing
-expl3, or keen to work on improved key management systems,
-are encouraged to try the package and provide feedback.
-
-keys3 is *not* an official LaTeX3 team package. Whether any of
-the ideas explored here will be taken up by the team is
-therefore unknown. However, the keys3 package should provide
-ideas on what needs to be available for key management and how
-it can be implemented.

-%\section{Key management}
-%
-% The key--value method is a popular system for creating large numbers
-% of settings for controlling function or package behaviour. For the
-% user, the system normally results in input of the form
-%\begin{verbatim}
-% \PackageControlMacro{
-% key-one = value one,
-% key-two = value two
-% }
-%\end{verbatim}
-% or
-%\begin{verbatim}
-% \PackageMacro[
-% key-one = value one,
-% key-two = value two
-% ]{argument}.
-%\end{verbatim}
-% For the programmer, the original \pkg{keyval} package gives only
-% the most basic interface for this work. All key macros have to be
-% created one at a time, and as a result the \pkg{kvoptions} and
-% \pkg{xkeyval} packages have been written to extend the ease of
-% creating keys. A very different approach has been provided by
-% the \pkg{pgfkeys} package, which uses a key--value list to
-% generate keys.
-%
-% The \pkg{keys3} package is aimed at creating a programming
-% interface for key--value controls in \LaTeX3. Keys are
-% created using a key--value interface, in a similar manner to
-% \pkg{pgfkeys}. Each key is created by setting one or more
-% \emph{properties} of the key:
-%\begin{verbatim}
-% \keys_define:nn { module }
-% key-one .code:n = code including parameter #1,
-% key-two .set = \l_module_store_tl
-% }
-%\end{verbatim}
-% These values can then be set as with other key--value approaches:
-%\begin{verbatim}
-% \keys_set:nn { module }
-% key-one = value one,
-% key-two = value two
-% }
-%\end{verbatim}
-%
-% At a document level, the \cs{keys_set:nn} macro used within a
-% document function. For \LaTeXe, a generic set up function could be
-% created with
-%\begin{verbatim}
-% \newcommand*\SomePackageSetup[1]{%
-% \@nameuse{keys_set:nn}{module}{#1}%
-% }
-%\end{verbatim}
-% or to use key--value input as the optional argument for a macro:
-%\begin{verbatim}
-% \newcommand*\SomePackageMacro[2][]{%
-% \begingroup
-% \@nameuse{keys_set:nn}{module}{#1}%
-% % Main code for \SomePackageMacro
-% \endgroup
-% }
-%\end{verbatim}
-% The same concepts using \pkg{xparse} for \LaTeX3 use:
-%\begin{verbatim}
-% \DeclareDocumentCommand \SomePackageSetup { m } {
-% \keys_set:nn { module } { #1 }
-% }
-% \DeclareDocumentCommand \SomePackageMacro { o m } {
-% \group_begin:
-% \keys_set:nn { module } { #1 }
-% % Main code for \SomePackageMacro
-% \group_end:
-% }
-%\end{verbatim}
-%
-% Key names may contain any tokens, as they are handled internally
-% using \cs{tl_to_str:n}. As will be discussed in
-% section~\ref{sec:subdivision}, it is suggested that the character
-% ``\texttt{/}'' is reserved for sub-division of keys into logical
-% groups. Macros are \emph{not} expanded when creating key names,
-% and so:
-%\begin{verbatim}
-% \tl_set:Nn \l_module_tmp_tl { key }
-% \keys_define:nn { module } {
-% \l_module_tmp_tl .code:n = code
-% }
-%\end{verbatim}
-% will create a key called \cs{l_module_tmp_tl}, and not one called
-% \texttt{key}.
-%
-%\subsection{Creating keys}
-%
-%\begin{function}{\keys_define:nn}
-% \begin{syntax}
-% "\keys_define:nn" <module> <keyval list>
-% \end{syntax}
-% Parses the <keyval list> and defines the keys listed there for
-% <module>. This function is designed for use in code, and therefore
-% does not check the category codes of characters or ignore spaces.
-%\end{function}
-%
-% Setting up and altering keys is carried out using one or more
-% properties. The properties determine how a key acts, and may require
-% zero, one or two argument: this is indicated by an argument specifier,
-% in the same way as a standard \LaTeX3 function. If only a single
-% argument is required, braces around \texttt{n} arguments can be
-% omitted.\footnote{This is a general feature of key--value input
-% methods.}
-%
-%\begin{function}{.choice:}
-% \begin{syntax}

-%\begin{function}{
-% .default:n|
-% .default:V|
-% }

-% \end{syntax}
-% Defines <key> to store the value given in <variable>. The type and
-% scope (local or global) of <variable> are determined from the
-% name. The \texttt{x} version performs an expanded assignment.
-% \begin{texnote}

-% }
-% \begin{syntax}
-% <key> .set_bool:N = <bool>
-% <key> .set_bool_inverse:N = <bool>
-% \end{syntax}
-% Defines <key> to set <bool> to <value> (which must be either
-% \texttt{true} or \texttt{false}). The \texttt{inverse} version sets
-% the switch to the opposite logical sense to the argument given.
-%\end{function}
-%
-%\begin{function}{

-%\subsection{Sub-dividing keys}
-%\label{sec:subdivision}
-%
-% When creating large numbers of keys, it may be desirable to divide
-% them into several sub-groups for a given module. This can be achieved
-% either by adding a sub-division to the module name:
-%\begin{verbatim}
-% \keys_define:nn { module / subgroup } {
-% key .code:n = code
-% }
-%\end{verbatim}
-% or to the key name:
-%\begin{verbatim}
-% \keys_define:nn { module } {
-% subgroup / key .code:n = code
-% }
-%\end{verbatim}
-% As illustrated, the best choice of token for sub-dividing keys in
-% this way is ``\texttt{/}''. This is because of the method that is
-% used to represent keys internally. Both of the above code fragments
-% set the same key, which has full name \texttt{module/subgroup/key}.
-%
-% As will be illustrated in the next section, this subdivision is
-% particularly relevant to making multiple choices.
-%
-%\subsection{Multiple choices}
-%\label{sec:choice}
-%
-% In \pkg{keys3}, multiple choices are created by setting the
-% \texttt{.choice:} property:
-%\begin{verbatim}
-% \keys_define:nn { module } {
-% key .choice:
-% }
-%\end{verbatim}
-% For keys which are set up as choices, the valid choices are generated
-% by creating sub-keys of the choice key. This can be carried out in
-% two ways.
-%
-% In many cases, choices execute similar code which is dependant only
-% on the name of the choice or the position of the choice in the
-% list of choices. Here, the keys can share the same code, and can
-% be rapidly created using the \texttt{.generate_choices:nn}
-% property:
-%\begin{verbatim}
-% \keys_define:nn { module } {
-% key .generate_choices:nn = {
-% choice-a, choice-b, choice-c
-% } {
-% You~gave~choice~``\l_keys_choice_tl'',~
-% which~is~in~position~\l_keys_choice_int
-% \~in~the~list.
-% }
-% }
-%\end{verbatim}
-%
-%\begin{variable}{
-% \l_keys_choice_tl|
-% \l_keys_choice_int|
-%}
-% Inside the code block, the variables \cs{l_keys_choice_tl} and
-% \cs{l_keys_choice_int} are available to indicate the name of the
-% current choice, and its position in the comma list. The position
-% is indexed from \(1\).
-%\end{variable}
-%
-% On the other hand, it is sometimes useful to create choices which
-% use entirely different code from one another. This can be achieved
-% by setting the \texttt{.choice:} property of a key, then manually
-% defining sub-keys.
-%\begin{verbatim}
-% \keys_define:nn { module } {
-% key choices:n,
-% key / choice-a .code:n = code-a,
-% key / choice-b .code:n = code-b,
-% key / choice-c .code:n = code-c,
-% }
-%\end{verbatim}
-%
-% It is possible to mix the two methods, but manually-created choices
-% should \emph{not} use \cs{l_keys_choice_tl} or \cs{l_keys_choice_int}.
-%
-%\subsection{Setting keys}
-%
-%\begin{function}{\keys_set:nn}
-% \begin{syntax}
-% "\keys_set:nn" <module> <keyval list>
-% \end{syntax}
-% Parses the <keyval list>, and sets those keys which are defined
-% for <module>. The behaviour on finding an unknown key can be
-% set by defining a special \texttt{unknown} key: this will be
-% illustrated later. In contrast to \cs{keys_define:nn}, this function
-% does check category codes and ignore spaces, and is therefore
-% suitable for user input.
-%\end{function}
-%
-% If a key is not known, \cs{keys_set:nn} will look for a special
-% \texttt{unknown} key for the same module. This mechanism can be
-% used to create new keys from user input.
-%\begin{verbatim}
-% \keys_define:nn { module } {
-% unknown .code:n =
-% You~tried~to~set~key~`\l_keys_path_tl'~to~`#1'
-% }
-%\end{verbatim}
-%
-%\begin{variable}{\l_keys_key_tl}
-% When processing an unknown key, the name of the key is available
-% as \cs{l_keys_key_tl}. Note that this will have been processed

-%
-%\section{Package options}
-%
-% The methods that \LaTeX3 will use to process package options are not
-% clear at the present time. However, in order to fully test the
-% \pkg{expl3} bundle fully, it is useful to be able to work with
-% the \LaTeXe\ system but using \LaTeX3 methods as far as possible.
-%
-% The \pkg{keys3} package provides an experimental method for
-% managing key--value input using \pkg{expl3} syntax. It is
-% self-contained and does not use any \LaTeXe methods. On the other
-% hand, \pkg{keys3opts2} is intended as a ``bridge'' between the
-% \LaTeXe\ kernel and \textsf{keys3}. It allows keys to be created
-% using \pkg{keys3} and processed by \LaTeXe\ as package or class
-% options.

-%\subsection{functions}
-%
-% \begin{function}{\keys_options_ltx:n}
-% \begin{syntax}
-% "\keys_options_ltx:n" <module>
-% \end{syntax}
-% The only macro for outside use. Processes the current option list
-% using the currently defined keys, checking if they exist for
-% <module>.

-%\subsection{Implementation}
-%
-% Almost everything here is based heavily on \pkg{pgfopts}, which is
-% itself a port of the appropriate code from \pkg{kvoptions} to work
-% with \pkg{pgfkeys}.
-%
-% As this package is an add-on to \pkg{keys3}, the same internal
-% module name (|\keys_|) is used here as in the main package. The lead
-% off as usual.
