-% \author{Copyright (C) 1994,1995 by Mike Piff}

-%
-% \section{Introduction}
-%
-% This package is a modification of the author's previous style option
-% |answers|, which has been in use for a few years,
-% and was based upon the
-% \TeX book idea of binding solutions to exercises. I have taken the
-% opportunity with this revision to alter the format of the solutions,
-% so that they are now presented as \LaTeX\ environments rather than
-% being started with a command and ended with the end of the surrounding
-% environment, a wholly un-\LaTeX y way of doing things!
-%
-% The other main change is that several file
-% handles are allowed to be active
-% at once. This allows some solutions in a book (for instance) to go
-% to the appendices, and some to go to a separate file, to be printed and
-% handed to the students as the course progresses.
-% Moreover, the actual physical files opened with each file handle
-% can now be varied in the same job, allowing many different files
-% to be created according to the same format. Thus, for instance,
-% each chapter of a book could create its own solution file, allowing
-% the user to use |\include| on both chapters and solutions.
-%
-% Finally, any number of solution-types may now be bound to any file, not
-% just the two old ones, solution and hint. The format of each solution
-% type is under the complete control of the user.
-%
-% \section{The documentation driver file}
-%
-% This is the driver file that produces this documentation.
-% We use the document class provided by the \LaTeXe\ distribution
-% for producing the documentation.
-% \begin{macrocode}
-%<*driver>
-\documentclass{ltxdoc}
-\RecordChanges
-\begin{document}
- \DocInput{answers.dtx}
- \PrintIndex
- \PrintChanges
-\end{document}
-%</driver>
-% \end{macrocode}
-%
-% \section{User interface}
-%
-% The package needs to be included with the command
-% \begin{verbatim}
-% \usepackage[nosolutionfiles]{answers}
-% \end{verbatim}
-% If the optional argument is given, solutions appear at that point
-% in the text, rather than being written to external files.
-% This allows a demonstrator's version to be produced.
-%
-% \DescribeMacro{\Newassociation}
-% After that, there should be several declarations of the form
-% \begin{verbatim}
-% \Newassociation{xxx}{yyy}{zzz}
-% \end{verbatim}
-% where |xxx| is an environment in the document, and |yyy| is an
-% environment which will surround the contents of |xxx| when it is
-% written to symbolic file handle |zzz|.
-% The names |xxx|, |yyy| and |zzz| should consist of letters
-% only, not numbers, punctuation or spaces.
-%
-% \DescribeMacro{\solutionextension}
-% By default, output will go to |zzz.tex| if |zzz| is open.
-% The command |\solutionextension| can be redefined to change |tex| to
-% some other extension. Alternatively, the output filename can be
-% changed as an optional parameter to |\Opensolutionfile|, and each
-% |\Opensolutionfile| on the same handle can use a different physical
-% file. By default, |\solutionpoint| is added before |\solutionextension|.
-% Redefine it to remove it. (It has the obvious default value of a
-% period.
-%
-% \DescribeMacro{\Opensolutionfile}
-% \DescribeMacro{\Closesolutionfile}
-% At some point the user types
-% \begin{verbatim}
-% \Opensolutionfile{zzz}
-% ...
-% \Closesolutionfile{zzz}
-% \end{verbatim}
-% to create a file of solutions written by environments |xxx| to
-% environments |yyy|.
-% If this construction is used several times, then several files
-% of solutions will be created.
-% The user may wish these files to have different names.
-% If the form |\Opensolutionfile{zzz}[www]|, then |www.tex| is used as
-% actual file output name rather than |zzz.tex|. This allows file
-% handle |zzz| to create many files |www.tex|, say one for each
-% chapter of a book, or one for each problem sheet. These could then
-% be processed using |\include| commands. The same value of
-% |\solutionextension| is used for the optional argument as for the
-% main argument.
-% The name |www| should follow the usual file naming conventions.
-%
-% \DescribeMacro{\Writetofile}
-% In addition, material can be written directly to a file by means of
-% |\Writetofile|.
-% Its first argument is the file handle |zzz| and its second is
-% the line of text to be written.
-% It is most important to remember that any control words
-% in the line to be written should be preceded by |\protect|,
-% otherwise the primitive \TeX\ |\write| command will expand them.
-% Also, as the argument is read in \TeX' usual way before being
-% written, any trailing spaces after a control word will disappear
-% unless precautions are taken. Thus, to write |\xx yyy| to the file,
-% the user can type |\protect\xx\space yyy|.
-%
-% \DescribeEnv{Filesave}
-% Alternatively, a block of text can be saved to file handle
-% |zzz| by means of
-% \begin{verbatim}
-% \begin{Filesave}{zzz}
-% ....
-% \end{Filesave}
-% \end{verbatim}
-% around it once, |zzz| has been opened.
-% The restrictions that apply to |\Writetofile| above do not apply
-% to this environment.
-%
-% \DescribeMacro{\Readsolutionfile}
-% One of the generated files can be read using
-% \begin{verbatim}
-% \Readsolutionfile{zzz}
-% \end{verbatim}
-% provided the file has not been closed and re-opened.
-% Alternatively, simply |\input| or |\include| it if preferred.
-%
-% None of the file operations should have any effect if the file
-% handle |zzz| has not been opened, or if |nosolutionfiles| is specified.
-%
-% \section{A simple example}
-%
-% Here is a straightforward example to illustrate how these macros
-% are used.

-% Three sorts of solution are written to two different files.

-% \begin{macrocode}
-\Newassociation{solution}{Soln}{test}
-\Newassociation{hint}{Hint}{test}

-% \section{The file interface}
-%
-% \begin{macro}{\Opensolutionfile}
-% Before we can write solutions, we must open the solution file(s).
-% The command to do this takes a single parameter, which should usually be
-% a file name without extension. Thus it should probably be
-% restricted to a string of at most 8 letters for portability.
-% This operation will not truncate any existing open file.
-% However, if the second optional parameter is specified, this
-% determines the actual filename, and the first parameter is then
-% an arbitrary symbolic file handle name.

-\def\Opensolutionfile#1{%

-% \end{macrocode}
-%
-% Note that the two file commands each provide a hook which allows them to
-% perform extra tasks.
-% For instance, the opening operation could be made to
-% write extra information to the file by redefining the appropriate hook.
-% The closing operation could if required do an immediate |\input| of the
-% solution file contents. For example,
-% \begin{verbatim}
-% \newcommand{\Openxxxhook}[2]{%
-% \Writetofile{#1}{\protect\section{#2}}%
-% }%
-% \newcommand{\Closexxxhook}[1]{%
-% \Readsolutionfile{#1}%

-% \end{verbatim}
-% and then
-% \begin{verbatim}
-% \Opensolutionfile{xxx}{Answers to selected problems}
-% ...
-% \Closesolutionfile{xxx}
-% \end{verbatim}
-% The default behaviour is to ignore the one parameter. Note that if you
-% redefine their behaviour, you must remember that the first parameter is
-% always the file handle.
-% \end{macro}
-% \end{macro}
-%
-% \begin{macro}{\Readsolutionfile}
-% The operation of reading the file of solutions can be done with the
-% following command.
-% \begin{macrocode}
-\def\Readsolutionfile#1{%
- \Ifanswerfiles{%
- \Iffileundefined{#1}{}{%

-% that is to write to one of these handles
-% must know which handle to write to,

-% by the command |\xxxlabel|, which takes one argument by default.
-% The argument is passed to it by the command |\xxxparams|,
-% which expands to |{\Currentlabel}|, a synonym for |{\@currentlabel}|,
-% and this argument is written automatically by the source environment.
-% The label appears in boldface by default.
-% We could easily change the behaviour of this environment by changing
-% these two commands. For example
-% \begin{verbatim}
-% \renewcommand{\xxxlabel}[1]{\emph{Solution to #1}}
-% \renewcommand{\xxxparams}{{\Currentlabel(p.\thepage)}}
-% \end{verbatim}
-% would provide a number and page reference in italic.
-%
-% More complicated behaviour could be produced by redefining the |xxx|
-% environment itself to take a different number of parameters. Note
-% however that |\xxxparams| must be redefined to provide those parameters.
