+# `luaoptions`
+Option handling for LuaLaTeX packages
+
+This package has been extracted from
+[`lyluatex`](https://github.com/jperon/lyluatex) where it was originally
+developed as supporting functionality. However, as it turned out it is useful
+as a building block for LuaLaTeX packages in general, and the development of
+[`luaformatters`](https://github.com/lualatex-tools/luaformatters) made it
+clear that the option handling code had to be moved to a standalone package.
+
+Initially there is no extensive documentation available since the package wasn't
+originally intended to be exposed to third-party packages or even end-users;
+the best sources of documentation are `lyluatex` and `luaformatters` codes,
+and the docstrings of `luaoptions.lua` and `luaoptions-lib.lua`.

+\section{Introduction}\label{introduction}}
+
+\texttt{luaoptions} is a LuaLaTeX package providing extensive support
+for handling \emph{options}, on package level and locally. It is hosted
+at \url{https://github.com/lualatex-tools/luaoptions} and maintained by
+Jacques Peron
+(\href{mailto:cataclop@hotmail.com}{\nolinkurl{cataclop@hotmail.com}})
+and Urs Liska
+(\href{mailto:git@ursliska.de}{\nolinkurl{git@ursliska.de}}). The
+package was originally developed as part of the \texttt{lyluatex}
+package\footnote{\url{https://github.com/jperon/lyluatex}} but has now
+been extracted as a standalone package because we realized it can be a
+useful tool for arbitrary LuaLaTeX packages having to deal with
+\emph{options} -- both \emph{package options} and \emph{optional macro
+arguments}. A \texttt{lyluatex} installation should not be a dependency
+for packages that want to make use of option handling but are not
+interested in music engraving \dots
+
+\texttt{luaoptions} allows the declaration of sets of options, along
+with defaults, expected/allowed values and limited type checking. These
+options can be enforced as package options, changed at any point during
+a document, or overwritten locally by optional macro arguments. It is
+also possible to instantiate an \texttt{Options} object as an
+independent Lua object, without linking it to a package.
+\texttt{luaoptions} can be used to enforce and prepopulate options, or
+it can be used to simply handle the parsing of optional
+\texttt{key=value} arguments into proper Lua tables.
+
+The main use of \texttt{luaoptions} is to define package options as
+follows:
+
+\begin{Shaded}
+\begin{Highlighting}[]
+\FunctionTok{\textbackslash{}RequirePackage}\NormalTok{\{luaoptions\}}
+\FunctionTok{\textbackslash{}directlua}\NormalTok{\{}
+\NormalTok{  local \_opt = lua\_options}
+\NormalTok{  lua\_options.register(\textquotesingle{}myoptions\textquotesingle{}, \{}
+\NormalTok{    [\textquotesingle{}option\textquotesingle{}] = \{\textquotesingle{}default value\textquotesingle{}, \textquotesingle{}other value\textquotesingle{}, \textquotesingle{}\textquotesingle{}\},}
+\NormalTok{    [\textquotesingle{}otheroption\textquotesingle{}] = \{\textquotesingle{}default\textquotesingle{}, validator\},}
+\NormalTok{    [\textquotesingle{}yetanotheroptions\textquotesingle{}] = \{\},}
+\NormalTok{  \})}
+\NormalTok{\}}
+\end{Highlighting}
+\end{Shaded}
+
+\texttt{validator} is a function that returns \texttt{true} when the
+defined option is valid, \texttt{false} otherwise. \texttt{luaoptions}
+itself contains predefined such functions.
+
+After that, defined options are available in a lua table, which can be
+used by the mean of the \texttt{client} command:
+
+\begin{Shaded}
+\begin{Highlighting}[]
+\KeywordTok{local}\NormalTok{ myopts }\OperatorTok{=}\NormalTok{ lua\_options}\OperatorTok{.}\NormalTok{client}\OperatorTok{(}\StringTok{\textquotesingle{}myoptions\textquotesingle{}}\OperatorTok{)}
+\NormalTok{tex}\OperatorTok{.}\NormalTok{sprint}\OperatorTok{(}\NormalTok{myopts}\OperatorTok{.}\NormalTok{option}\OperatorTok{)}
+\end{Highlighting}
+\end{Shaded}
+
+This initial release does \emph{not} include documentation beyond this
+short introduction; please refer to the docstrings in
+\texttt{luaoptions.lua} and \texttt{luaoptions-lib.lua} for more
+information.
+
+For the time being it is possible to look into how some of our own
+packages make use of \texttt{luaoptions}:
