% \title{The |catechis| Package, v2.6} \author{Donald P.\

%
% \maketitle
%
% \begin{abstract}
% \noindent
% The catechism (a text consisting of explicitly-stated and
% usually numbered questions and answers) has long been an
% important vehicle for teaching the basics of concepts.
% \LaTeX, however, does not by default have much facility
% for producing such texts. The |catechis| package provides
% a number of highly customizable macros for writing
% catechisms, including a numbered question-and-answer
% environment; comments on answers; and citations.
% \end{abstract}
%
% \tableofcontents
%
% \section{Introduction}
%
% Catechisms are largely known for basic religious
% instruction, and this has indeed been their primary use.
% For this reason alone, \LaTeX\ ought to have some
% facilities for authoring them. Furthermore, the form is
% useful for other topics, as well; it provides an easy way
% to give basic information on a topic, making it easily
% extractable by eye from the full text, while still
% allowing more advanced discussion for those who wish to
% plunge more deeply into a given question.
%
% |catechis| is packaged according to the \LaTeX\
% \textsc{docstrip} utility, which allows automatic
% extraction of code and documentation from the same files.
%
% This is version 2.0 of |catechis|; it represents a mostly
% complete rewrite of the package, which is therefore much
% simpler and more robust.
%
% \section{The State of the \TeX\ for Catechisms}
% \label{sect:state}
%
% \LaTeX\ has basically no provision for producing
% well-formed catechisms. It's easy enough to fake it, of
% course; for example:
%
% \begin{verbatim}
% \begin{enumerate}
% \item\textbf{Who made us?} \\ God made us.
% \item\textbf{Why did God make us?} \\ God made us to
% know Him, love Him, and serve Him, and by so doing
% to gain everlasting life with Him in Heaven.
% \end{enumerate}
% \end{verbatim}
%
% This gives the following result:
%
% \exline
%\begin{enumerate}
% \item\textbf{Who made us?} \\ God made us.
% \item\textbf{Why did God make us?} \\ God made us to
% know Him, love Him, and serve Him, and by so doing
% to gain everlasting life with Him in Heaven.
%\end{enumerate}
% \exline
%
% However, this solution is far from satisfactory. It's
% unportable, fit really only for this one document;
% uncustomizable, because it's hard-wired to do only this
% one thing; unmodifiable, at least automatically, because
% it uses explicit visual formatting in the text; and far
% too wordy. What is desired is something more along the
% lines of the following:
%
% \begin{verbatim}
% \catques{Who made us?}{God made us.}
% \catques{Why did God make us?}{God made us to
% know Him, love Him, and serve Him, and by so doing
% to gain everlasting life with Him in Heaven.}
% \end{verbatim}
%
% Which, with the |catechis| package, produces this:
%
% \exline
% \catques{Who made us?}{God made us.}
% \catques{Why did God make us?}{God made us to
% know Him, love Him, and serve Him, and by so doing
% to gain everlasting life with Him in Heaven.}
% \catques{What will happen if the question is really long,
% so that it wraps to the next line?}{It will work properly,
% with the wrapped line appropriately indented. The answer,
% as you have already seen, will behave likewise.}
% \exline
%
% |catechis| provides these facilities and more to produce
% high-quality, useful catechisms.
%
% \section{Basic Usage}
% \label{sect:basics}
%
% The most basic usage of |catechis| is encompassed by the
% \DescribeMacro{\catques}|\catques| macro:
%
% \begin{center}
% \cmd{\catques} \marg{question} \marg{answer}
% \end{center}
%
% There is no more to this than meets the eye. Both
% arguments are mandatory, though either may be empty; the
% first is the question, and the second is the answer. It
% is often helpful to indent sensibly to keep these more
% readable in the source:
%
% \begin{verbatim}
% \catques{What is the question?}{%
% The question is, ``What is the question?''}%
% \end{verbatim}
%
% This produces the following:
%
% \exline
% \catques{What is the question?}{The question is, ``What is the question?''}%
% \exline
%
% Our next macro, \DescribeMacro{\catcomment}|\catcomment|,
% really shows the genius of the catechism concept. The
% question and answer are the \emph{basic} information; it's
% easily followed up by a comment, which is visually
% separate and can be skipped by those interested in, or
% only ready for, the basics, but is still sensibly placed
% and ready for those who wish it.
%
% \exline
% \catques{What is the question?}{The question is, ``What is the question?''}%
% \catcomment{This is a comment. It's very interesting, it
% wraps and indents correctly, and the package's default
% comment style is demonstrated here.}
% \catques{How are the questions numbered? Are they
% numbered sequentially, throughout the text?}{Yes, the
% questions are numbered sequentially throughout the text.
% You can reset the numbers manually, which we'll talk about
% later; but by default, there is one question stream which
% is numbered from 1 on up.}
% \catcomment{We're numbering questions sequentially to show
% that you can have catechism questions scattered throughout
% a text, or your text can be entirely in the form of a
% catechism. |catechis| works either way.}
% \exline
%
% There is also the \DescribeMacro{\catexplic}|\catexplic|
% command, which works essentially identically to
% |\catcomment| but can include paragraph breaks and is
% intended for much lengthier commentary on the answer.
%
% \begin{verbatim}
% \catques{What is the question?}{The question is, ``What is the question?''}%
% \catcomment{This is a comment. It's very interesting, it
% wraps and indents correctly, and the package's default
% comment style is demonstrated here.}
% \catexplic{We can make some really impressive things
% happen with this command. While comments allow
% short explanatory comments on an answer, explics
% give us field to go on for a long time, if we want.
%
% We can put in paragraph breaks, and we can even do the
% following:
% \begin{compactenum}
% \item We can put lists in them!
% \item Isn't that cool? This can provide a great way to
% give advanced information on a topic that people can read
% if they want, or just skip on to the next question!
% \end{compactenum}\restoreindents
%
% You can really produce beautiful catechetical works using
% this facility, which will do a great job of instructing
% people at all levels of expertise.
% }%
% \end{verbatim}
%
% \exline
% \catques{What is the question?}{The question is, ``What is the question?''}%
% \catcomment{This is a comment. It's very interesting, it
% wraps and indents correctly, and the package's default
% comment style is demonstrated here.}
% \catexplic{We can make some really impressive things
% happen with this command. While comments allow
% short explanatory comments on an answer, explics
% give us field to go on for a long time, if we want.
%
% We can put in paragraph breaks, the indentation of which
% we can control with fine granularity; and we can even do the
% following:
%
% \begin{compactenum}
% \item We can put lists in them!
% \item Isn't that cool? This can provide a great way to
% give advanced information on a topic that people can read
% if they want, or just skip on to the next question!
% \end{compactenum}\restoreindents
%
% You can really produce beautiful catechetical works using
% this facility, which will do a great job of instructing
% people at all levels of expertise.
%
% }%
% \exline
%
% You'll note that lists \emph{will} hose all of
% |catechis|'s careful indentation, so after using one in a
% |\catexplic|, you must issue
% \DescribeMacro{\restoreindents}|\restoreindents| to get
% everything back to normal.
%
% Catechisms also routinely provide citations to support
% their claims; |catechis| provides for this, too. A
% heading for a group of citations is printed by issuing
% \DescribeMacro{\catcitetitle}|\catcitetitle|, and each
% individual citation is printed by issuing the |\catcite|
% command, which takes the citation as the first argument
% and the source as the second:
%
% \begin{center}
% \DescribeMacro{\catcite}
% \cmd{\catcite} \marg{citation} \marg{source}
% \end{center}
%
% An example:
%
% \begin{verbatim}
% \catcitetitle
% \catcite{For the apparel oft proclaims the man.}{Polonius}
% \catcite{And this above all: to thine own self be true; /
% and it must follow, as the night the day, / that thou
% canst not be false to any man.}{Polonius}
% \end{verbatim}
%
% \exline
% \catcitetitle
% \catcite{For the apparel oft proclaims the man.}{Polonius}
% \catcite{And this above all: to thine own self be true; /
% and it must follow, as the night the day, / that thou
% canst not be false to any man.}{Polonius}
% \exline
%
% Because this will often not result in proper spacing,
% |catechis| provides an environment,
% \DescribeMacro{catcitations}|catcitations|, which
% will insert appropriate spacing before and after the
% citations. This environment will automatically run
% |\catcitetitle| for you.
%
% \begin{verbatim}
% \begin{catcitations}
% \catcite{For the apparel oft proclaims the man.}{Polonius}
% \catcite{And this above all: to thine own self be true; /
% and it must follow, as the night the day, / that thou
% canst not be false to any man.}{Polonius}
% \end{catcitations}
% \end{verbatim}
%
% \exline
% \begin{catcitations}
% \catcite{For the apparel oft proclaims the man.}{Polonius}
% \catcite{And this above all: to thine own self be true; /
% and it must follow, as the night the day, / that thou
% canst not be false to any man.}{Polonius}
% \end{catcitations}
% \exline
%
% Lastly, |catechis| gives some provisions for more
% customary catechetical enumerates. It uses standard
% features from the |paralist| package for this, and simply
% makes those the default.
%
% \begin{verbatim}
% \catques{Can we do enumerates?}{Yes, we can do those; we
% can even do them in a special way, so that it looks more
% like the way catechisms customarily look.}
% \catcomment{Just check this out; we have here a comment
% giving slightly more detailed information, then an
% enumerate giving \emph{much} more detailed information.}
% \begin{enumerate}
% \item Here, we have the first item, with some extra
% details elaborating on what was said before.
% \item Here, we have another item.
% \item Here, we have still another.
% \end{enumerate}
% \end{verbatim}
%
% \exline
% \catques{Can we do enumerates?}{Yes, we can do those; we
% can even do them in a special way, so that it looks more
% like the way catechisms customarily look.}
% \catcomment{Just check this out; we have here a comment
% giving slightly more detailed information, then an
% enumerate giving \emph{much} more detailed information.}
% \begin{compactenum}
% \item Here, we have the first item, with some extra
% details elaborating on what was said before.
% \item Here, we have another item.
% \item Here, we have still another.
% \end{compactenum}
% \exline
%
% \section{Customization}
% \label{sect:custom}
%
% Pretty much everything in the package can be customized.
% The names of the necessary commands and lengths are fairly
% predictable: they will start with |\cat|, be followed by
% the type of thing (|ques|, |comm|, |explic|, etc.), and
% then the property to be set (|sty|, |indent|, |hindent|,
% etc.).
%
% In all cases, lengths are set with |\setlength|, while
% commands are set with |\newcommand| or |\def|.
%
% \begin{description}
% \vitem|catquesnum| \DescribeMacro{catquesnum} The counter
% which |catechis| maintains for the questions. It can be
% set or reset with the usual \LaTeX\ counter commands
% (e.g., |\setcounter|, |\addtocounter|).
% \vitem|\thecatquesnum| \DescribeMacro{\thecatquesnum} The
% actual typeset version of |catquesnum|. By default, this
% is defined as |\renewcommand{\thecatquesnum}{\arabic{catquesnum}.}|.
% \vitem|\catquesnumwd| \DescribeMacro{\catquesnumwd} The
% width of the box in which |catechis| typesets the question
% number. By default, |2em|.
% \vitem|\catquesindent| \DescribeMacro{\catquesindent}
% The indentation of the first line of the question in
% |\catques|. By default, |0em|.
% \vitem|\catqueshindent| \DescribeMacro{\catqueshindent}
% The indentation of subsequent lines of the question in
% |\catques|. By default, |2em|.
% \vitem|\catquessty| \DescribeMacro{\catquessty} The style
% in which the question will be printed in |\catques|. By
% default, |\bfseries|.
% \vitem|\catansindent| \DescribeMacro{\catansindent}
% The indentation of the first line of the answer in
% |\catques|. By default, |2em|.
% \vitem|\catanshindent| \DescribeMacro{\catanshindent}
% The indentation of subsequent lines of the answer in
% |\catques|. By default, |2em|.
% \vitem|\catanssty| \DescribeMacro{\catanssty} The style
% in which the answer will be printed in |\catques|. By
% default, empty.
% \vitem|\catcommindent| \DescribeMacro{\catcommindent}
% The indentation of the first line of the comment in
% |\catcomment|. By default, |2em|.
% \vitem|\catcommhindent| \DescribeMacro{\catcommhindent}
% The indentation of subsequent lines of the comment in

% Finally, the list settings are all from |paralist|, so
% that package's documentation should be consulted for
% changing the defaults set up for them.
%
% These options are sufficient to manipulate |catechis|
% into behaving however you'd like.
%
% \section{Implementation}
%
% Start by requiring |paralist|, to take care of our custom
% enumerates.
% \begin{macrocode}
\RequirePackage{paralist}
\setdefaultenum{(a)}{(1)}{(i)}{(A)}
\setdefaultleftmargin{3.8em}{}{}{}{}{}
% \end{macrocode}
% Now we create the indentations and styles for the default
% question counter, the questions themselves, and the
% answers. We also set sensible defaults.
% \begin{macrocode}
\newlength{\catquesindent}\setlength{\catquesindent}{0em}
\newlength{\catqueshindent}\setlength{\catqueshindent}{2em}
\newlength{\catansindent}\setlength{\catansindent}{2em}
\newlength{\catanshindent}\setlength{\catanshindent}{2em}
\newlength{\catquesnumwd}\setlength{\catquesnumwd}{2em}
\newcounter{catquesnum}\setcounter{catquesnum}{0}
\def\catquesnumsty{\bfseries}
\def\catquessty{\bfseries}
\def\catanssty{}
\renewcommand{\thecatquesnum}{\arabic{catquesnum}.}
% \end{macrocode}
% Here, we define the catechism question macro. Nothing
% much surprising here.
% \begin{macrocode}
\def\catques#1#2{%
\stepcounter{catquesnum}%
\def\@currentlabel{\thecatquesnum}%
{\parindent=\catquesindent\hangindent=\catqueshindent\hangafter=1%
{\par\leavevmode\hbox to\catquesnumwd{\catquesnumsty\thecatquesnum\hfil}%
\catquessty #1}\par\nobreak}%
{\parindent=\catansindent\hangindent=\catanshindent\hangafter=1%
{\par\catanssty #2}\par}%
}%
% \end{macrocode}
% Define the catechism comments, and set sensible defaults
% for the settings.
% \begin{macrocode}
\def\catcommsty{}
\newlength{\commindent}\setlength{\commindent}{2em}
\newlength{\commhindent}\setlength{\commhindent}{2em}
\def\catcomment#1{%
{\parindent=\commindent\hangindent=\commhindent\hangafter=1%
{\par\catcommsty #1}\par}
}%
% \end{macrocode}
% Define the catechism explications (longer than comments,
% allowing paragraph breaks), and set sensible defaults for
% their settings.
% \begin{macrocode}
\def\catexplicsty{\small}
\newlength{\explicindent}\setlength{\explicindent}{4em}
\newlength{\explichindent}\setlength{\explichindent}{2em}
\long\def\catexplic#1{%
{\par\everypar={\parindent=\explicindent\hangindent=\explichindent\hangafter=1}%
{\par\catexplicsty\ #1}\par}%
}%
% \end{macrocode}
% Because lists always seem to run roughshod over
% indentation settings, and because it's easier to do this
% than to write custom lists just for this package, we
% define |\restoreindents| to fix settings after a list in a
% |\catexplic|.
% \begin{macrocode}
\def\restoreindents{%
\par%
\everypar={%
\parindent=\explicindent%
\hangindent=\explichindent%
\hangafter=1%
}%
\par%
}%
% \end{macrocode}
% Define the commands to produce citation titles, and set
% sensible defaults; also for the citation environment.
% \begin{macrocode}
\def\catcitetitlesty{\Large\scshape}%
\def\catcitetitleword{Citations}%
\def\catcitetitle{%
\hbox to\linewidth{%
\hfil%
{\catcitetitlesty\catcitetitleword}%
\hfil%
}%
\penalty10000%
}%
\newlength\catcitationbefskip\catcitationbefskip=1em%
\newlength\catcitationaftskip\catcitationaftskip=1em%
\def\catcitations{%
\leavevmode%
\vskip\catcitationbefskip%
\catcitetitle%
}%
\def\endcatcitations{%
\leavevmode%
\vskip\catcitationaftskip%
}%
% \end{macrocode}
% Define actual citations macros and lengths.
% \begin{macrocode}
\def\catcitesty{\itshape}%
\def\catsrcsty{}%
\newlength{\catciteindent}\setlength{\catciteindent}{0em}%
\newlength{\catcitehindent}\setlength{\catcitehindent}{0em}%
\newlength{\catsrcindent}\setlength{\catsrcindent}{2em}%
\newlength{\catsrchindent}\setlength{\catsrchindent}{2em}%
\def\catcite#1#2{%
{\parindent=\catciteindent\hangindent=\catcitehindent\hangafter=1%
{\par\catcitesty #1}\par}%
\penalty10000%
{\parindent=\catsrcindent\hangindent=\catsrchindent\hangafter=1%
{\par\catsrcsty#2}\par}%
}%
\let\scripture=\catcite
% \end{macrocode}

% And that's it. Happy \TeX{}ing!
