|

|
% A central thing in \LaTeX is the usage of \enquote{theorems}.
|
||||||
|
% With \enquote{theorems} we actually mean \enquote{environments} that typically
|
||||||
|
% have a title, some style applied to their contents and are numbered throughout
|
||||||
|
% the document, often later referenced by number and / or name.
|
||||||
|
%
|
||||||
|
% Mechanisms for generating such environments are packages like
|
||||||
|
% \pkg{amsthm}, \pkg{ntheorem}, \pkg{thmtools}.
|
||||||
|
%
|
||||||
|
% While the mechanism in \pkg{thmtools} are pretty versatile and suffice
|
||||||
|
% for almost all needs, it is pretty time-consuming to largely change
|
||||||
|
% the behavior of environments, or have small variants of these.
|
||||||
|
%
|
||||||
|
% This package aims at both providing a versatile mechanism, \meta{theorem group}s,
|
||||||
|
% to structure theorems into groups that can subsequently easily altered,
|
||||||
|
% as well as a mechanism for easily generating \meta{theorem families}.
|
||||||
|
%
|
||||||
|
% As the author is of the opinion that of the mentioned theorem controlling packages
|
||||||
|
% \pkg{thmtools} provides the most versatile interface, the \pkg{groupthm}
|
||||||
|
% will be working on top of \pkg{thmtools} and use this as a backend for declaring
|
||||||
|
% the \meta{theorem}s themselves.
|
||||||
|
%
|
||||||
|
% Thus, any styles supported by \pkg{thmtools} will be supported by \pkg{groupthm}
|
||||||
|
% as well, by passing them to \pkg{thmtools}.

|
||||||
|
% \subsection{Theorem groups}
|
||||||
|
% \label{sec:theorem-groups}
|
||||||
|
% A \meta{theorem group} is some named group holding some properties for
|
||||||
|
% the \meta{theorem}s that are contained in this group.
|
||||||
|
% Each \meta{theorem} can, when declared, be part of arbitrarily many \meta{theorem group}s,
|
||||||
|
% and will be subject to the styles these groups defined.
|
||||||
|
%
|
||||||
|
% This enables to group similar \meta{theorem}s and alter them at a late stage of
|
||||||
|
% document development in a unique manner, by only having to change the
|
||||||
|
% definition of the \meta{theorem group}, and not all \meta{theorem}s separately.
|
||||||
|
%
|
||||||
|
% The properties. such a \meta{theorem group} can hold are as follows
|
||||||
|
%
|
||||||
|
%
|
||||||
|
% \begin{description}
|
||||||
|
% \item[\kw{prename}] A prefix (any \meta{token list}) that will be inserted
|
||||||
|
% before the theorem name of each member of this \meta{theorem group}.
|
||||||
|
% \item[\kw{postname}] A suffix (any \meta{token list}) that will be
|
||||||
|
% inserted before the theorem name for each member of this \meta{theorem group}.
|
||||||
|
% This could be e.g.~some \enquote{$\star$} appended to the name to indicate
|
||||||
|
% variants of environments.
|
||||||
|
% \item[\kw{mapname}] A \meta{function} (some macro that takes exactly one argument)
|
||||||
|
% that is applied to the \kw{name}.
|
||||||
|
% \item[\kw{thmtools}] A \meta{clist} of key-value pairs that are passed to the underlying
|
||||||
|
% \pkg{thmtools} backend of the \meta{theorem}.
|
||||||
|
% This allows e.g.~to set the \kw{topskip} of a certain class of \meta{theorem}s.
|
||||||
|
% \end{description}
|
||||||
|
%
|
||||||
|
% The most versatile key here is certainly the \kw{thmtools} key,
|
||||||
|
% providing the most customization to an end user (like you).
|
||||||
|
%
|
||||||
|
% As mentioned, each \meta{theorem} can be member of arbitrary many \meta{theorem group}s,
|
||||||
|
% and will posses their corresponding properties.
|
||||||
|
%
|
||||||
|
% To adjust finer controlling of these \meta{theorem group}s, \meta{theorem group}s can inherit from each other, and \meta{theorem group}s are subject to a hierarchy that controls precedence in case
|
||||||
|
% of conflicting properties of different \meta{theorem group}s a \meta{theorem} may be part of.
|
||||||
|
%
|
||||||
|
% This hierarchy can of course be controlled by the user.
|
||||||
|
%
|
||||||
|
% \subsection{Grouped theorems}
|
||||||
|
%
|
||||||
|
% A \meta{grouped theorem} is just a theorem that is a member of
|
||||||
|
% a given set of groups (possibly empty).
|
||||||
|
% It behaves just a regular theorem, except that by changing the definition of
|
||||||
|
% its theorem groups, we can alter its behavior.
|
||||||
|
%
|
||||||
|
%
|
||||||
|
% It is the core concept of the \pkg{groupthm} package.
|
||||||
|
% For brevity, we will often talk about \enquote{theorems},
|
||||||
|
% although in fact we mean \enquote{grouped theorems}.
|
||||||
|
%
|
||||||
|
% \subsection{Theorem families}
|
||||||
|
% Often, one needs some small \meta{theorem variant}s of some \meta{theorem}, the most typical
|
||||||
|
% example being \vocab{starred} version of \meta{theorem}s that are not numbered
|
||||||
|
% in contrast to their counterparts.
|
||||||
|
%
|
||||||
|
% \begin{verbatim}
|
||||||
|
% \begin{theorem}
|
||||||
|
% This theorem is numbered.
|
||||||
|
% \end{theorem}
|
||||||
|
%
|
||||||
|
% \begin{theorem*}
|
||||||
|
% This theorem is not numbered.
|
||||||
|
% Probably because we do not want a reference to it.
|
||||||
|
% \end{theorem*}
|
||||||
|
% \end{verbatim}
|
||||||
|
% \todo{insert code example output}
|
||||||
|
%
|
||||||
|
% \pkg{groupthm} extends this idea and provides a versatile mechanism to define a
|
||||||
|
% \meta{theorem family}, which is based on some \meta{theorem name} and
|
||||||
|
% parses additional arguments / syntax to control the \meta{theorem groups}
|
||||||
|
% that this environment is a part of.
|
||||||
|
%
|
||||||
|
% So, in addition the name of a \meta{theorem}, the corresponding environment will
|
||||||
|
% accept some options and toggle the membership of certain \meta{theorem groups},
|
||||||
|
% thus further customizing its appearance.
|
||||||
|
%
|
||||||
|
% This can lead e.g.~to usages like the following:
|
||||||
|
%
|
||||||
|
% \begin{verbatim}
|
||||||
|
% \begin{theorem}*
|
||||||
|
% This theorem has a visual * at its name.
|
||||||
|
% \end{theorem}
|
||||||
|
% \end{verbatim}
|
||||||
|
% \todo{code}
|
||||||
|
%
|
||||||
|
% Providing this consists of two parts:
|
||||||
|
% declaring the \meta{theorem family} by listing the groups that can be toggled
|
||||||
|
% by this \meta{theorem family}, and declaring the actual option parsing
|
||||||
|
% of the \meta{theorem family}, which then controls the membership in these groups
|
||||||
|
% (and of course prior to this the definition of the desired \meta{theorem group}s).
|
||||||
|
%
|
||||||
|
%
|
||||||
|
%
|
||||||
|
% \subsection{General notions}
|
||||||
|
%
|
||||||
|
% In many cases, there are a number of variants of some command,
|
||||||
|
% call it for example \cs{Foo}.
|
||||||
|
% Then the documentation will look like
|
||||||
|
% %
|
||||||
|
% \begin{function}{\NewFoo, \RenewFoo, \ProvideFoo, \DeclareFoo}
|
||||||
|
% Defines some \kw{foo} \ldots
|
||||||
|
% \end{function}
|
||||||
|
% %
|
||||||
|
% and will not mention anything about the variants.
|
||||||
|
% This follows some general naming convention that also \pkg{xparse} uses,
|
||||||
|
% and is the following:
|
||||||
|
%
|
||||||
|
% \begin{description}
|
||||||
|
% \item[\cs{NewFoo}]
|
||||||
|
%
|
||||||
|
% Defines \kw{foo} if not defined already.
|
||||||
|
% This emits an error in case it has been defined yet.
|
||||||
|
%
|
||||||
|
% \item[\cs{RenewFoo}]
|
||||||
|
%
|
||||||
|
% Redefines \kw{foo} if defined already.
|
||||||
|
% This emits an error in case it has \emph{not} been defined yet.
|
||||||
|
%
|
||||||
|
% \item[\cs{ProvideFoo}]
|
||||||
|
%
|
||||||
|
% Defines \kw{foo} if it is not defined already.
|
||||||
|
% This does not emit an error if \kw{foo} is already defined
|
||||||
|
% (and has no effect in this case).
|
||||||
|
%
|
||||||
|
% \item[\cs{DeclareFoo}]
|
||||||
|
%
|
||||||
|
% Defines \kw{foo} in disregard of any
|
||||||
|
% existing definitions. Any old definition will be overwritten (if present).
|
||||||
|
% \end{description}
|
||||||
|
% %
|
||||||
|
% The documentation margin will list all variants that are available,
|
||||||
|
% they follow their respective conventions.
|
||||||
|
%
|
||||||
|
%
|
||||||
|
% \begin{texnote}
|
||||||
|
% The \pkg{thmtools} package, unfortunately, dose not follow this convention,
|
||||||
|
% as its \cs{declaretheorem} command actually behaves like a \cs{newtheorem}.
|
||||||
|
% The reason for this is that \pkg{amsthm} already defines \cs{newtheorem}.
|
||||||
|
%
|
||||||
|
% Thus, actually, calls to \cs{NewGroupedTheorem} will have an underlying
|
||||||
|
% \cs{declaretheorem}, but you do not have to bother with this.

% The \meta{keys} available are the same as introduced in \autoref{sec:theorem-groups}:

% Inheritance is transitive, when defining a new theorem, we just flatten out the

|

|
% The reason for the two groups \kw{starred} and \kw{unnumbered}
|
||||||
|
% to both exist is that the \kw{starred} group is \emph{meant} to be applied
|
||||||
|
% to theorems that were called with a \enquote{*} in their name (thus the name),
|
||||||
|
% whereas the \enquote{unnumbered} group \emph{means} that the environment
|
||||||
|
% is 'just unnumbered'.
|
||||||
|
%
|
||||||
|
% This has two reasons:
|
||||||
|
% First, this enables more fine-tuning of the behavior of the theorems in post-processing
|
||||||
|
% of a document.
|
||||||
|
% Second, more importantly, this distinguishes semantically between the environments
|
||||||
|
% \kw{theorem} and \kw{theorem*}, even if \kw{theorem} is in the \kw{unnumbered} group.
|
||||||
|
%
|
||||||
|
% So assuming that \kw{theorem} is member of the \kw{unnumbered} group, both calls
|
||||||
|
%
|
||||||
|
% \begin{verbatim}
|
||||||
|
% \begin{theorem}
|
||||||
|
% This is not numbered.
|
||||||
|
% \end{theorem}
|
||||||
|
% \begin{theorem*}
|
||||||
|
% This is not numbered.
|
||||||
|
% \end{theorem*}
|
||||||
|
% \end{verbatim}
|
||||||
|
%
|
||||||
|
% are defined and will produce the same result by default, but we could still
|
||||||
|
% change the definition of the \kw{starred} group later to do anything we want.

|
||||||

A central thing in \LaTeX is the usage of \enquote{theorems}.
|
|
||||||
With \enquote{theorems} we actually mean \enquote{environments} that typically
|
|
||||||
have a title, some style applied to their contents and are numbered throughout
|
|
||||||
the document, often later referenced by number and / or name.
|
|
||||||
|
|
||||||
Mechanisms for generating such environments are packages like
|
|
||||||
\pkg{amsthm}, \pkg{ntheorem}, \pkg{thmtools}.
|
|
||||||
|
|
||||||
While the mechanism in \pkg{thmtools} are pretty versatile and suffice
|
|
||||||
for almost all needs, it is pretty time-consuming to largely change
|
|
||||||
the behavior of environments, or have small variants of these.
|
|
||||||
|
|
||||||
This package aims at both providing a versatile mechanism, \meta{theorem group}s,
|
|
||||||
to structure theorems into groups that can subsequently easily altered,
|
|
||||||
as well as a mechanism for easily generating \meta{theorem families}.
|
|
||||||
|
|
||||||
As the author is of the opinion that of the mentioned theorem controlling packages
|
|
||||||
\pkg{thmtools} provides the most versatile interface, the \pkg{groupthm}
|
|
||||||
will be working on top of \pkg{thmtools} and use this as a backend for declaring
|
|
||||||
the \meta{theorem}s themselves.
|
|
||||||
|
|
||||||
Thus, any styles supported by \pkg{thmtools} will be supported by \pkg{groupthm}
|
|
||||||
as well, by passing them to \pkg{thmtools}.

||||||

|
||||||
\section{Concepts}

|
|
||||||
\subsection{Theorem groups}
|
|
||||||
\label{sec:theorem-groups}
|
|
||||||
A \meta{theorem group} is some named group holding some properties for
|
|
||||||
the \meta{theorem}s that are contained in this group.
|
|
||||||
Each \meta{theorem} can, when declared, be part of arbitrarily many \meta{theorem group}s,
|
|
||||||
and will be subject to the styles these groups defined.
|
|
||||||
|
|
||||||
This enables to group similar \meta{theorem}s and alter them at a late stage of
|
|
||||||
document development in a unique manner, by only having to change the
|
|
||||||
definition of the \meta{theorem group}, and not all \meta{theorem}s separately.
|
|
||||||
|
|
||||||
The properties. such a \meta{theorem group} can hold are as follows
|
|
||||||
|
|
||||||
|
|
||||||
\begin{description}
|
|
||||||
\item[\kw{prename}] A prefix (any \meta{token list}) that will be inserted
|
|
||||||
before the theorem name of each member of this \meta{theorem group}.
|
|
||||||
\item[\kw{postname}] A suffix (any \meta{token list}) that will be
|
|
||||||
inserted before the theorem name for each member of this \meta{theorem group}.
|
|
||||||
This could be e.g.~some \enquote{$\star$} appended to the name to indicate
|
|
||||||
variants of environments.
|
|
||||||
\item[\kw{mapname}] A \meta{function} (some macro that takes exactly one argument)
|
|
||||||
that is applied to the \kw{name}.
|
|
||||||
\item[\kw{thmtools}] A \meta{clist} of key-value pairs that are passed to the underlying
|
|
||||||
\pkg{thmtools} backend of the \meta{theorem}.
|
|
||||||
This allows e.g.~to set the \kw{topskip} of a certain class of \meta{theorem}s.
|
|
||||||
\end{description}
|
|
||||||
|
|
||||||
The most versatile key here is certainly the \kw{thmtools} key,
|
|
||||||
providing the most customization to an end user (like you).
|
|
||||||
|
|
||||||
As mentioned, each \meta{theorem} can be member of arbitrary many \meta{theorem group}s,
|
|
||||||
and will posses their corresponding properties.
|
|
||||||
|
|
||||||
To adjust finer controlling of these \meta{theorem group}s, \meta{theorem group}s can inherit from each other, and \meta{theorem group}s are subject to a hierarchy that controls precedence in case
|
|
||||||
of conflicting properties of different \meta{theorem group}s a \meta{theorem} may be part of.
|
|
||||||
|
|
||||||
This hierarchy can of course be controlled by the user.
|
|
||||||
|
|
||||||
\subsection{Grouped theorems}
|
|
||||||
|
|
||||||
A \meta{grouped theorem} is just a theorem that is a member of
|
|
||||||
a given set of groups (possibly empty).
|
|
||||||
It behaves just a regular theorem, except that by changing the definition of
|
|
||||||
its theorem groups, we can alter its behavior.
|
|
||||||
|
|
||||||
|
|
||||||
It is the core concept of the \pkg{groupthm} package.
|
|
||||||
For brevity, we will often talk about \enquote{theorems},
|
|
||||||
although in fact we mean \enquote{grouped theorems}.
|
|
||||||
|
|
||||||
\subsection{Theorem families}
|
|
||||||
Often, one needs some small \meta{theorem variant}s of some \meta{theorem}, the most typical
|
|
||||||
example being \vocab{starred} version of \meta{theorem}s that are not numbered
|
|
||||||
in contrast to their counterparts.
|
|
||||||
|
|
||||||
\begin{verbatim}
|
|
||||||
\begin{theorem}
|
|
||||||
This theorem is numbered.
|
|
||||||
\end{theorem}
|
|
||||||
|
|
||||||
\begin{theorem*}
|
|
||||||
This theorem is not numbered.
|
|
||||||
Probably because we do not want a reference to it.
|
|
||||||
\end{theorem*}
|
|
||||||
\end{verbatim}
|
|
||||||
\todo{insert code example output}
|
|
||||||
|
|
||||||
\pkg{groupthm} extends this idea and provides a versatile mechanism to define a
|
|
||||||
\meta{theorem family}, which is based on some \meta{theorem name} and
|
|
||||||
parses additional arguments / syntax to control the \meta{theorem groups}
|
|
||||||
that this environment is a part of.
|
|
||||||
|
|
||||||
So, in addition the name of a \meta{theorem}, the corresponding environment will
|
|
||||||
accept some options and toggle the membership of certain \meta{theorem groups},
|
|
||||||
thus further customizing its appearance.
|
|
||||||
|
|
||||||
This can lead e.g.~to usages like the following:
|
|
||||||
|
|
||||||
\begin{verbatim}
|
|
||||||
\begin{theorem}*
|
|
||||||
This theorem has a visual * at its name.
|
|
||||||
\end{theorem}
|
|
||||||
\end{verbatim}
|
|
||||||
\todo{code}
|
|
||||||
|
|
||||||
Providing this consists of two parts:
|
|
||||||
declaring the \meta{theorem family} by listing the groups that can be toggled
|
|
||||||
by this \meta{theorem family}, and declaring the actual option parsing
|
|
||||||
of the \meta{theorem family}, which then controls the membership in these groups
|
|
||||||
(and of course prior to this the definition of the desired \meta{theorem group}s).
|
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
\subsection{General notions}
|
|
||||||
|
|
||||||
In many cases, there are a number of variants of some command,
|
|
||||||
call it for example \cs{Foo}.
|
|
||||||
Then the documentation will look like
|
|
||||||
%
|
|
||||||
\begin{function}{\NewFoo, \RenewFoo, \ProvideFoo, \DeclareFoo}
|
|
||||||
Defines some \kw{foo} \ldots
|
|
||||||
\end{function}
|
|
||||||
%
|
|
||||||
and will not mention anything about the variants.
|
|
||||||
This follows some general naming convention that also \pkg{xparse} uses,
|
|
||||||
and is the following:
|
|
||||||
|
|
||||||
\begin{description}
|
|
||||||
\item[\cs{NewFoo}]
|
|
||||||
|
|
||||||
Defines \kw{foo} if not defined already.
|
|
||||||
This emits an error in case it has been defined yet.
|
|
||||||
|
|
||||||
\item[\cs{RenewFoo}]
|
|
||||||
|
|
||||||
Redefines \kw{foo} if defined already.
|
|
||||||
This emits an error in case it has \emph{not} been defined yet.
|
|
||||||
|
|
||||||
\item[\cs{ProvideFoo}]
|
|
||||||
|
|
||||||
Defines \kw{foo} if it is not defined already.
|
|
||||||
This does not emit an error if \kw{foo} is already defined
|
|
||||||
(and has no effect in this case).
|
|
||||||
|
|
||||||
\item[\cs{DeclareFoo}]
|
|
||||||
|
|
||||||
Defines \kw{foo} in disregard of any
|
|
||||||
existing definitions. Any old definition will be overwritten (if present).
|
|
||||||
\end{description}
|
|
||||||
%
|
|
||||||
The documentation margin will list all variants that are available,
|
|
||||||
they follow their respective conventions.
|
|
||||||
|
|
||||||
|
|
||||||
\begin{texnote}
|
|
||||||
The \pkg{thmtools} package, unfortunately, dose not follow this convention,
|
|
||||||
as its \cs{declaretheorem} command actually behaves like a \cs{newtheorem}.
|
|
||||||
The reason for this is that \pkg{amsthm} already defines \cs{newtheorem}.
|
|
||||||
|
|
||||||
Thus, actually, calls to \cs{NewGroupedTheorem} will have an underlying
|
|
||||||
\cs{declaretheorem}, but you do not have to bother with this.
|
|
||||||
\end{texnote}

\section{Theorem groups}
|
|
||||||
|
|
||||||
\subsection{Defining theorem groups}
|
|
||||||
|
|
||||||
\begin{function}{\NewTheoremGroup, \RenewTheoremGroup, \ProvideTheoremGroup, \DeclareTheoremGroup}
|
|
||||||
\begin{syntax}
|
|
||||||
\cs{NewTheoremGroup}[\meta{keys}]\{\meta{theorem group}\}
|
|
||||||
\end{syntax}
|
|
||||||
|
|
||||||
This introduces a new \meta{theorem group} with the given name.
|
|
||||||
The \meta{keys} available are the same as introduced in \autoref{sec:theorem-groups}:
|
|
||||||
|
|
||||||
\begin{description}
|
|
||||||
\item
|
|
||||||
|
|
||||||
\kw{prename} = \meta{token list}.
|
|
||||||
Insert the \meta{token list} in front of the theorem name.
|
|
||||||
|
|
||||||
\item
|
|
||||||
|
|
||||||
\kw{postname} = \meta{token list}.
|
|
||||||
Insert the \meta{token list} after the theorem name.
|
|
||||||
|
|
||||||
\item
|
|
||||||
|
|
||||||
\kw{mapname} = \meta{function}.
|
|
||||||
Apply this \meta{function} to the theorem name.
|
|
||||||
|
|
||||||
\item
|
|
||||||
|
|
||||||
\kw{thmtools} = $\{$\meta{clist}$\}$.
|
|
||||||
Pass these options to \pkg{thmtools}.
|
|
||||||
|
|
||||||
\end{description}
|
|
||||||
|
|
||||||
For uniqueness of the given options, the \meta{clist} given to the \kw{thmtools} key
|
|
||||||
has to be surrounded by a pair of braces.
|
|
||||||
|
|
||||||
\begin{texnote}
|
|
||||||
The \kw{mapname} is expected to be a function of \cs{fun:n}.
|
|
||||||
It is subject to an \kw{x}-type expansion prior to being passed further to \pkg{thmtools}.
|
|
||||||
\end{texnote}
|
|
||||||
|
|
||||||
\end{function}
|
|
||||||
|
|
||||||
\subsection{Controlling theorem group precedence}
|
|
||||||
|
|
||||||
\begin{function}{\DeclareTheoremGroupRule}
|
|
||||||
\begin{syntax}
|
|
||||||
\cs{DeclareTheoremGroupRule}[\meta{keyname}]%
|
|
||||||
\{\meta{theorem group 1}\}\{\meta{relation}\}\{\meta{theorem group 2}\}
|
|
||||||
\end{syntax}
|
|
||||||
|
|
||||||
This declares some relation between the two theorem groups,
|
|
||||||
controlling their order of application in case a theorem is member
|
|
||||||
of both groups.
|
|
||||||
|
|
||||||
The \meta{keyname} can be one of \kw{prename}, \kw{postname}, \kw{mapname}, \kw{thmtools}.
|
|
||||||
If present, it declares the corresponding relation only for this subkey.
|
|
||||||
This can lead to \meta{theorem group 1} overwriting \meta{theorem group 2} when given
|
|
||||||
contradictory \pkg{thmtools} options, but the \kw{prename} of \meta{theorem group 1}
|
|
||||||
being applied after the one of \meta{theorem group 2}.
|
|
||||||
When the \meta{keyname} is not given, this applies to all keywords.
|
|
||||||
|
|
||||||
\begin{texnote}
|
|
||||||
The \meta{keyname} is just passed to the corresponding argument
|
|
||||||
of the \kw{lthooks} package.
|
|
||||||
If the option argument is not present, \kw{??} is used, this has the described effect.
|
|
||||||
\end{texnote}
|
|
||||||
|
|
||||||
The behavior of the relations is based on the \cs{DeclareHookRule} command
|
|
||||||
from the \pkg{xparse} package, and all respective keys are in fact available,
|
|
||||||
but typically not needed, so the reader of this manual is referred to the
|
|
||||||
\todoref{lthooks} packages documentation for a list of the full keys.
|
|
||||||
For us, the following list will suffice:
|
|
||||||
|
|
||||||
\begin{description}
|
|
||||||
\item[\kw{higher} or \kw{after} or \kw{\string>}]
|
|
||||||
|
|
||||||
\meta{theorem group 1} takes precedence over \meta{theorem group 2}.
|
|
||||||
Its \kw{prename} is applied after the one of \meta{theorem group 2}.
|
|
||||||
|
|
||||||
\item[\kw{lower} or \kw{before} or \kw{\string<}]
|
|
||||||
|
|
||||||
\meta{theorem group 2} takes precedence over \meta{theorem group 1}.
|
|
||||||
Its \kw{prename} is applied after the one of \meta{theorem group 1}.
|
|
||||||
|
|
||||||
\end{description}
|
|
||||||
|
|
||||||
\begin{texnote}
|
|
||||||
The \meta{relation} is first stripped,
|
|
||||||
then checked if it matches either \kw{higher} or \kw{lower}
|
|
||||||
and in this case replaced by the corresponding \pkg{lthooks} variant
|
|
||||||
of the relation.
|
|
||||||
The rest is passed as is to \pkg{lthooks} and thus subject to the usual
|
|
||||||
normalization process of \pkg{lthooks}.
|
|
||||||
\end{texnote}
|
|
||||||
|
|
||||||
\end{function}
|
|
||||||
|
|
||||||
|
|
||||||
\subsection{Inheritance of theorem groups}
|
|
||||||
\begin{function}{\AddTheoremGroupParent}
|
|
||||||
\begin{syntax}
|
|
||||||
\cs{AddTheoremGroupParent}\{\meta{theorem group 1}\}\{\meta{theorem group 2}\}
|
|
||||||
\end{syntax}
|
|
||||||
Declares \meta{theorem group 1} to \enquote{inherit} all properties
|
|
||||||
of \meta{theorem group 2}.
|
|
||||||
In other words, \meta{theorem group 2} is a parent of \meta{theorem group 1}
|
|
||||||
in a usual inheritance graph.
|
|
||||||
|
|
||||||
The definitions of the groups themselves are unchanged,
|
|
||||||
but each new theorem defined with \meta{theorem group 1} will also
|
|
||||||
have the properties of \meta{theorem group 2}.
|
|
||||||
|
|
||||||
Inheritance is transitive, when defining a new theorem, we just flatten out the
|
|
||||||
inheritance graph and apply all properties.
|
|
||||||
|
|
||||||
Inheritance is subject to the usual theorem group hierarchies as discussed in \todoref.
|
|
||||||
This can even yield to situations, where \meta{theorem group 1} inherits
|
|
||||||
from \meta{theorem group 2}, but \meta{theorem group 2} overwrites
|
|
||||||
\meta{theorem group 1}.
|
|
||||||
\end{function}
|
|
||||||
|
|
||||||
\subsection{Appending to theorem groups}
|
|
||||||
\begin{function}{\AppendToTheoremGroup}
|
|
||||||
\begin{syntax}
|
|
||||||
\cs{AppendToTheoremGroup}[\meta{keys}]\{\meta{theorem group}\}
|
|
||||||
\end{syntax}
|
|
||||||
Adds the properties given as \meta{keys} to the theorem group.
|
|
||||||
The syntax for the \meta{keys} is the same as in \cs{NewTheoremGroup}.
|
|
||||||
\end{function}
|
|
||||||
|
|
||||||
\subsection{Default theorem groups}
|
|
||||||
|
|
||||||
There are a number of theorem groups that \pkg{group them} will initially declare
|
|
||||||
and that have certain special treatment in some places.
|
|
||||||
|
|
||||||
\begin{function}{all}
|
|
||||||
Every declared grouped theorem is a member of this group.
|
|
||||||
|
|
||||||
Initially, this group has no effect (i.e.~an empty property list).
|
|
||||||
It can be redefined by the user to alter the behavior of all grouped theorems
|
|
||||||
in a unified way.
|
|
||||||
|
|
||||||
It is the lowest theorem group in the hierarchy by default.
|
|
||||||
\end{function}
|
|
||||||
|
|
||||||
\begin{function}{starred}
|
|
||||||
This is group that shall represent the standard variant of theorems that
|
|
||||||
are called with a \enquote{*} in the environment name.
|
|
||||||
Theorems of this group are not numbered.
|
|
||||||
|
|
||||||
The user should not add theorems to this group by hand,
|
|
||||||
as this is handled in a unified way by default.
|
|
||||||
\todoref{}
|
|
||||||
|
|
||||||
It is the highest theorem group in the hierarchy by default,
|
|
||||||
except for \cs{unnumbered},
|
|
||||||
with which it has no relation.
|
|
||||||
\end{function}
|
|
||||||
\addtocounter{footnote}{-1}
|
|
||||||
|
|
||||||
\begin{function}{unnumbered}
|
|
||||||
Theorems in this group are not numbered.
|
|
||||||
|
|
||||||
It is the highest theorem group in the hierarchy by default,
|
|
||||||
except for \cs{starred},
|
|
||||||
with which it has no relation.
|
|
||||||
\end{function}
|
|
||||||
|
|
||||||
The reason for the two groups \kw{starred} and \kw{unnumbered}
|
|
||||||
to both exist is that the \kw{starred} group is \emph{meant} to be applied
|
|
||||||
to theorems that were called with a \enquote{*} in their name (thus the name),
|
|
||||||
whereas the \enquote{unnumbered} group \emph{means} that the environment
|
|
||||||
is 'just unnumbered'.
|
|
||||||
|
|
||||||
This has two reasons:
|
|
||||||
First, this enables more fine-tuning of the behavior of the theorems in post-processing
|
|
||||||
of a document.
|
|
||||||
Second, more importantly, this distinguishes semantically between the environments
|
|
||||||
\kw{theorem} and \kw{theorem*}, even if \kw{theorem} is in the \kw{unnumbered} group.
|
|
||||||
|
|
||||||
So assuming that \kw{theorem} is member of the \kw{unnumbered} group, both calls
|
|
||||||
|
|
||||||
\begin{verbatim}
|
|
||||||
\begin{theorem}
|
|
||||||
This is not numbered.
|
|
||||||
\end{theorem}
|
|
||||||
\begin{theorem*}
|
|
||||||
This is not numbered.
|
|
||||||
\end{theorem*}
|
|
||||||
\end{verbatim}
|
|
||||||
|
|
||||||
are defined and will produce the same result by default, but we could still
|
|
||||||
change the definition of the \kw{starred} group later to do anything we want.
|
|
||||||
|
|
||||||
\begin{texnote}
|
|
||||||
The mentioned hierarchies are kept intact for newly defined theorem groups,
|
|
||||||
i.e.~for each new such group, two theorem group rules are created.
|
|
||||||
\end{texnote}

\section{Grouped Theorems}
|
|
||||||
|
|
||||||
\subsection{Defining grouped theorems}
|
|
||||||
|
|
||||||
\begin{function}{\NewGroupedTheorem, \ProvideGroupedTheorem}
|
|
||||||
\begin{syntax}
|
|
||||||
\cs{NewGroupedTheorem}[\meta{keys}]\{\meta{theorem name}\}
|
|
||||||
\end{syntax}
|
|
||||||
This defines \meta{theorem name} as a new theorem environment.
|
|
||||||
Its properties can be set by the following keys:
|
|
||||||
|
|
||||||
\begin{description}
|
|
||||||
|
|
||||||
\item
|
|
||||||
|
|
||||||
\kw{name} $=$ \meta{displayed name}.
|
|
||||||
If given, this is the displayed name of the environment in the document.
|
|
||||||
If not present, the \meta{theorem name} is also used as the \meta{displayed name}
|
|
||||||
in capitalized form.
|
|
||||||
|
|
||||||
\item
|
|
||||||
|
|
||||||
\kw{group} $=$ \{\meta{clist}\}
|
|
||||||
|
|
||||||
Makes this theorem a member of the listed groups.
|
|
||||||
It will inherit all respective properties of these groups.
|
|
||||||
|
|
||||||
If groups are present more than one time, this has no (additional) effect.
|
|
||||||
|
|
||||||
\item
|
|
||||||
|
|
||||||
\kw{thmtools} = \{\meta{clist}\}
|
|
||||||
|
|
||||||
Passes these option to the \pkg{thmtools} environment that is declared internally.
|
|
||||||
|
|
||||||
\end{description}
|
|
||||||
\end{function}
|
|
||||||
|
|
||||||
\begin{function}{\NewGroupedTheorem*,\ProvideGroupedTheorem*}
|
|
||||||
\begin{syntax}
|
|
||||||
\cs{NewGroupedTheorem*}[\meta{keys}]\{\meta{theorem name}\}
|
|
||||||
\end{syntax}
|
|
||||||
Behaves the same as \cs{NewGroupedTheorem},
|
|
||||||
but also adds the theorem to the default \kw{unnumbered} group,
|
|
||||||
thus resulting in the environment not being numbered.
|
|
||||||
|
|
||||||
This is thus equivalent to using \cs{NewGroupedTheorem} and adding the
|
|
||||||
\kw{unnumbered} group.
|
|
||||||
\end{function}
|
|
||||||
|
|
||||||
\begin{function}{\NewTheorem, \ProvideTheorem}
|
|
||||||
\begin{syntax}
|
|
||||||
\cs{NewTheorem}[\meta{keys}]\{\meta{theorem name}\}
|
|
||||||
\end{syntax}
|
|
||||||
|
|
||||||
This behaves essentially the same as \cs{NewGroupedTheorem},
|
|
||||||
but will define two grouped theorems, namely \meta{theorem name} and \meta{theorem name*}.
|
|
||||||
|
|
||||||
The \meta{theorem name*} environment has the same properties as the \meta{theorem name},
|
|
||||||
but will be member of the \kw{starred} theorem group.
|
|
||||||
It is thus not recommended to call \cs{NewTheorem}
|
|
||||||
with an actual \enquote{*} in the environment name, since both environments
|
|
||||||
will be generated.
|
|
||||||
\end{function}
|
|
||||||
|
|
||||||
\begin{function}{\NewTheorem*, \ProvideTheorem*}
|
|
||||||
\begin{syntax}
|
|
||||||
\cs{NewTheorem}[\meta{keys}]\{\meta{theorem name}\}
|
|
||||||
\end{syntax}
|
|
||||||
Combines the behavior of \cs{NewGroupedTheorem*} and \cs{NewTheorem}, thus
|
|
||||||
declaring \meta{theorem} to (additionally) be member of the \kw{unnumbered}
|
|
||||||
and \meta{theorem*} to (additionally) be member of the \kw{starred} group.
|
|
||||||
|
|
||||||
As mentioned in \todoref, by default both environments will behave the same.
|
|
||||||
\end{function}
|
|
||||||
|
|
||||||
\subsection{Defining families of grouped theorems}
|
|
||||||
|
|
||||||
\begin{function}{\NewGroupedTheoremFamily, \ProvideGroupedTheoremFamily}
|
|
||||||
\begin{syntax}
|
|
||||||
\cs{NewTheoremFamily}[\meta{keys}]\{\meta{theorem name}\}
|
|
||||||
\end{syntax}
|
|
||||||
|
|
||||||
Defines a family of grouped theorems.
|
|
||||||
The \meta{keys} accept the same arguments as the \cs{NewGroupedTheorem} macro.
|
|
||||||
However, for each \emph{subset} of the given groups,
|
|
||||||
a grouped theorem is defined.
|
|
||||||
|
|
||||||
These grouped theorems are not meant to be accessed directly (but could),
|
|
||||||
so we omit their actual (internal) names here.
|
|
||||||
To call these, some \kw{GroupedTheoremFamilyOptions} have to specified,
|
|

|
||||||
\end{function}
|
|
||||||
|
|
||||||
\begin{function}{\NewGroupedTheoremFamily*, \ProvideGroupedTheoremFamily*}
|
|
||||||
Behaves the same as \cs{NewGroupedTheoremFamily}, but also adds each variant
|
|
||||||
to the default \kw{unnumbered} group, thus resulting in the environments not being
|
|
||||||
numbered.
|
|
||||||
|
|
||||||
This is \emph{almost} equivalent to calling \cs{NewGroupedTheoremFamily}
|
|
||||||
with the \kw{unnumbered} group being present, as it does not generate the variants
|
|
||||||
where the \kw{unnumbered} group is not present.
|
|
||||||
\end{function}
|
|
||||||
|
|
||||||
\begin{function}{\NewTheoremFamily, \ProvideTheoremFamily}
|
|
||||||
This behaves essentially the same as \cs{NewGroupedTheoremFamily},
|
|
||||||
but will add the \kw{starred} group to the list of groups and also generate variants
|
|
||||||
for these.
|
|
||||||
|
|
||||||
It is thus not recommended to call \cs{NewTheoremFamily} with the \kw{starred}
|
|
||||||
group explicitly given, since this is added anyways.
|
|
||||||
\end{function}
|
|
||||||
|
|
||||||
\begin{function}{\NewTheoremFamily*, \ProvideTheoremFamily*}
|
|
||||||
Combines the behavior of \cs{NewGroupedTheoremFamily*} and \cs{NewTheoremFamily}, thus
|
|
||||||
declaring all variants to (additionally) be member of the \kw{unnumbered}
|
|
||||||
group, and also generates definitions with and without the \kw{starred} group.
|
|
||||||
|
|
||||||
As mentioned in \todoref, by default both environments will behave the same.
|
|
||||||
\end{function}
|
|
||||||
|
|

\begin{function}{\AddTheoremToGroup}
|

||||||
\begin{syntax}
|
|
||||||
\cs{AddTheoremToGroup}\{\meta{theorem group}\}
|
|
||||||
\end{syntax}
|
|
||||||
|
|
||||||
Means that the current invocation of a theorem family should
|
|
||||||
call the theorem variant with the given group.
|
|
||||||
|
|
||||||
Can only be used in the body of \cs{NewGroupedTheoremFamilyOptions} or similarly.
|
|
||||||
\end{function}
|
|
||||||
|
|
||||||
\begin{function}
|
|
||||||
{
|
|
||||||
\NewGroupedTheoremFamilyOptions, \RenewGroupedTheoremFamilyOptions,
|
|
||||||
\ProvideGroupedTheoremFamilyOptions, \DeclareGroupedTheoremFamilyOptions
|
|
||||||
}
|
|
||||||
\begin{syntax}
|
|
||||||
\cs{NewGroupedTheoremFamilyOptions}\{\meta{theorem name}\}\{\meta{argument specifiation}\}%
|
|
||||||
\{\meta{selection body}\}
|
|
||||||
\end{syntax}
|
|
||||||
|
|
||||||
Defines a new environment with options, given by \meta{theorem name}.
|
|
||||||
The \meta{argument specification} can be any valid \pkg{xparse} argument specification.
|
|
||||||
|
|
||||||
The \meta{selection body} is there to process the options of
|
|
||||||
the \meta{argument specification} and select which variant of the \meta{theorem name}
|
|
||||||
to enter.
|
|
||||||
The arguments are available as usual with \pkg{xparse} by \kw{\#1}, \kw{\#2}, \ldots
|
|
||||||
|
|
||||||
The body may also call any number of \cs{AddTheoremToGroup} calls,
|
|
||||||
which enables the corresponding groups.
|
|
||||||
|
|
||||||
When the environment is called within the document, the options are parsed
|
|
||||||
as with \pkg{xpars} and the \meta{selection body} is executed.
|
|
||||||
Immediately after, the theorem variant of \meta{theorem name} with the specified groups
|
|
||||||
by \cs{AddTheoremToGroup} is called.
|
|
||||||
|
|
||||||
At the end of the environment, the \meta{selection body} is executed again and the
|
|
||||||
called theorem variant is ended again.
|
|
||||||
|
|
||||||
The possible theorem variants that the newly declared environment will call
|
|
||||||
\emph{have to be generated subsequently} by a call to the \cs{NewGroupedTheoremFamily}
|
|
||||||
function.
|
|
||||||
|
|
||||||
\end{function}
|
|
||||||
|
|
||||||
\begin{function}
|
|
||||||
{
|
|
||||||
\NewGroupedTheoremFamilyOptions*, \RenewGroupedTheoremFamilyOptions*,
|
|
||||||
\ProvideGroupedTheoremFamilyOptions*, \DeclareGroupedTheoremFamilyOptions*
|
|
||||||
}
|
|
||||||
\begin{syntax}
|
|
||||||
\cs{NewGroupedTheoremFamilyOptions*}\{\meta{theorem name}\}\{\meta{argument specifiation}\}%
|
|
||||||
\{\meta{selection body}\}
|
|
||||||
\end{syntax}
|
|
||||||
|
|
||||||
Does the same as \cs{NewGroupedTheoremFamilyOptions},
|
|
||||||
but calls the variants with the additional \kw{unnumbered} group.
|
|
||||||
|
|
||||||
The possible theorem variants have to be generated
|
|
||||||
with the \cs{NewGroupedTheoremFamily*} command before.
|
|
||||||
|
|
||||||
\end{function}
|
|
||||||
|
|
||||||
\begin{function}
|
|
||||||
{
|
|
||||||
\NewTheoremFamilyOptions, \RenewTheoremFamilyOptions,
|
|
||||||
\ProvideTheoremFamilyOptions, \DeclareTheoremFamilyOptions
|
|
||||||
}
|
|
||||||
\begin{syntax}
|
|
||||||
\cs{NewTheoremFamilyOptions}\{\meta{theorem name}\}\{\meta{argument specifiation}\}%
|
|
||||||
\{\meta{selection body}\}
|
|
||||||
\end{syntax}
|
|
||||||
|
|
||||||
This behaves essentially the same as \cs{NewGroupedTheoremFamilyOptions},
|
|
||||||
but also declares the environment \meta{theorem name*},
|
|
||||||
which behaves the same but calls the theorem variants with the additional \kw{starred}
|
|
||||||
subgroup.
|
|
||||||
|
|
||||||
The possible theorem variants have to be generated with the \cs{NewTheoremFamily}
|
|
||||||
command before.
|
|
||||||
|
|
||||||
\end{function}
|
|
||||||
|
|
||||||
\begin{function}
|
|
||||||
{
|
|
||||||
\NewTheoremFamilyOptions*, \RenewTheoremFamilyOptions*,
|
|
||||||
\ProvideTheoremFamilyOptions*, \DeclareTheoremFamilyOptions*
|
|
||||||
}
|
|
||||||
|
|
||||||
Combines the behavior of \cs{NewGroupedTheoremFamilyOptions*} and \cs{NewTheoremFamilyOptions},
|
|
||||||
thus declaring both \meta{theorem name} and \meta{theorem name*} environments,
|
|
||||||
the latter calling the \kw{starred} variants of the theorem family,
|
|
||||||
and both of them calling \kw{unnumbered} variants of the family.
|
|
||||||
|
|
||||||
The possible theorem variants have to be generated with the \cs{NewTheoremFamily*}
|
|
||||||
command before.
