-exam-n: LaTeX class file for exams, version 1.1.4, 2016 December 19.
-====================================
-
-[ Mercurial revision e8a612cb25f4, 2016-12-19 16:49 +0000, tag exam-n-1.1.4 + 0 ]
-
-
-Overview
---------
-
-The class is designed to be localised to a particular institution's
-exam layout, by a suitably skilled LaTeX hacker. There are three
-possible ways of doing this, in increasing order of sophistication:
-
- 1. Make suitable adjustments to individual exam `.tex` files; or
-
- 2. Rename the distributed `exam-n.dtx` file to something more locally
- suitable, and edit it with suitable changes (search for
- `%%%CONFIGURE` for hints on where to adjust); or
-
- 3. Fork the Mercurial repository at
- [bitbucket](https://bitbucket.org/nxg/exam-n), change the
- value of the `EXAM-N` variable in the `Makefile`, and then
- edit the `exam-n.dtx` file. See the comments at the top of the
- `Makefile`.
-
-In case 2, you _must_ change the name of the `.dtx` file, and in case
-3, you must change the `EXAM-N` variable, to avoid terrible confusion
-(you probably also want to avoid the names of the other exam style
-files at CTAN, since they just might have found their way into your
-TEXINPUTS path).
-
-For general details, talk to Norman Gray <norman@astro.gla.ac.uk>.
-
-This is free software, and you are encouraged to use and adapt it as
-you see fit. Norman can give advice. If, however, you need more
-substantial help with the customisations of option 3 above, or need
-continuing support, then we can surely arrange something more
-elaborate.
-
-With the version 1.1 release, the interface should now be regarded
-as rather stable. However version 1.1 was the first to be released
-outside Glasgow University, so there may be some changes to the
-interface which will emerge with broader use, as well as some bug
-fixes. The interface _may_, therefore, yet change. If you use
-this class to produce exams, it would be wise to include a copy of
-the class file locally, rather than relying on a central version. If
-you need an earlier version of the class, let me know.
-
-
-Documentation
-------------
-
- * Documentation for question authors is in `notes-for-authors.pdf`.
- * The full version of the documentation, for 'exam conveners' (or
- equivalent) is in `exam-n.pdf`. This and the author
- documentation are built as part of the distribution.
- * Basic documentation for a LaTeX localiser is in this file (see
- above), with extra remarks at the top of the `Makefile`.
-
-There are brief release notes in exam-n.html.

+% \Lopt{mathtime}, \Lopt{mtpro2}, \Lopt{stix2}]
+% The \Lopt{cmfonts} option (the default) uses the Computer Modern fonts for the
+% document, and the other options use PostScript or OpenType fonts.
+%
+% The \Lopt{mathtime} or \Lopt{mtpro2} options select PostScript
+% Times Roman, Helvetica and Courier for the body text, plus either Mathtime or
+% Mathtime Professional~2 to typeset maths (this is commercially
+% distributed by
+% PC\TeX\footnote{\url{https://www.pctex.com/mtpro2.html}}, and
+% designed to be compatible with Times Roman). A broadly
+% compatible alternative to this is to use the \Lopt{mathptm}
+% option, but although this is free, the results aren't impressive.
+%
+% A final option is to use the \Lopt{stix2} option to choose
+% specifically and exclusively the
+% (free) STIX2 font set\footnote{\url{https://www.stixfonts.org}}
+% for both text and maths.
+% On this site, you will need to download and install
+% the files in the \url{static_otf.zip} bundle.
+% Note that the support for this option is somewhat experimental, and
+% at present, this package simply uses (serif) STIX2 roman
+% for all font shapes. Since the exam style doesn't use any sans serif by
+% default, this doesn't matter, at some level. The
+% \Lopt{sansserif} option is not compatible with this option (the option
+% won't produce any error, but neither will it produce any effect).
+%
+% \textbf{FIXME: remove this when unicode-math is working.}
+% \textbf{Note:} because of an unfortunate interaction between packages, the
+% \Lpackage{stix2} and \Lpackage{siunitx} packages can produce unexpected
+% results with some combinations of \TeX\ engine and package version
+% (specifically, \Lpackage{stix2} plus \Lpackage{siunitx}
+% and \cmd|\micro| or \cmd|\circ| can produce garbled characters
+% without \LaTeX\ reporting an error). Before \TeX Live 2021, this
+% worked correctly with Xe\LaTeX\ and Lua\LaTeX, but not with
+% pdf\LaTeX; from \TeX Live 2021 this works as expected with
+% pdf\LaTeX, but works with the other two \emph{only} if you load
+% the \Lpackage{siunitx} package with
+% \cmd|\usepackage{siunitx}[=v2]|. I hope that future versions of
+% one or other of these packages will make clear how this package
+% should handle them, in a way which avoids this special-casing.

+%
+% The handling of non-standard fonts has always been slightly
+% fragile in \LaTeX.
+% The \Lopt{mtpro2} and \Lopt{stix2} options are those currently
+% most used by the author, and are therefore the ones most likely
+% to get the various font nuances correct.
+%
+% \item[\Lopt{uprightpi}]By default $\pi$ is set slanted, as is the
+% usual \LaTeX\ default. When this is referring to the circular
+% constant, however, this should (in some typesetting styles) be set as an upright letter, in
+% fonts which support this. If the option \Lopt{uprightpi} is
+% present, then |\pi| is defined to produce an upright letter, and
+% the command |\italicpi| is defined to produce the slanted version.
+% Whether this option is supplied or not, the macro |\uppi| will
+% produce a single upright~$\pi$.
+% Note: this is at present implemented
+% only for the \Lopt{mtpro2} and \Lopt{stix2} options,

+% \subsubsection{Partmarks}
+%
% |\partmarks| is used at the end of a paragraph to indicate the
% number of marks associated with this part. The starred variant
-% |\partmarks*| is used when the end of a part is the end of a display
+% |\partmarks*| is used only when the end of a part is the end of a display
% maths block which doesn't have an equation number. This moves the
% part note up a bit, which looks nicer.
+%
+% It's also permissible to use |\partmarks| in the solution, to
+% indicate precisely where marks accrue. It's reasonable for this to
+% be more fine-grained than in the question. We don't check that the
+% partmarks in the solution add up to the mark goal.
+%
+% Manage the partmarks comments as the contents of a zero-width hbox,
+% which is sized to fit reasonably well in the margin. We insert this
+% into the output just before formatting the partmarks.
+%
+% The |\defaultpartmarkscategory| macro creates a default partmarks
+% `category'. If this is something like |{category?}|, then this
+% should prompt question authors to indicate the category in each call
+% to |\partmarks|. This can be declared within a |.clo| option file
+% (and is declared above, so that it can be read from there without error).
+%
+% Below, we must add the footnote text after the end of the paragraph,
+% otherwise this inserts vertical mode material, which causes a
+% linebreak, at least in the case where the last line is almost full.
+% Because we are using the hook mechanism, this package now depends on
+% the expl3 modules, and thus on TeXLive versions which aren't too old
+% (how old is too old? I'm not sure, but I expect TeXLive 2020 is new enough).

+% where the command is located inside a display (ie, in \TeX\ terms,
+% inside |$$...$$|); in these situations we have to use the
+% \texttt{.../after} hook instead. Such displays are most typically amsmath
+% alignment environments, but an \cmd|\halign| inside a display will
+% also qualify (see the discussion of `alignment displays' in \TeX
+% Book ch.19). There isn't a completely straightforward way of
+% detecting this situation (though amsmath's \cmd|\start@align| sets
+% \cmd|\xatlevel@| to be non-\cmd|\@empty|, which we take to indicate the
+% amsmath case), so we have to rely on the caller of this
+% command to invoke the \texttt{...@display} or \texttt{...@nodisplay}
+% variant appropriately.

+% \end{macrocode}
+%
+% First, define the questions version, for appearing in the version candidates see.
+% Here, \cmd|#1| is the possibly empty `classification' text, and \cmd|#2| is the
+% number of marks. At this point |\if@tempswa| is true if we got here
+% via the \cmd|\partmarks*| variant, and false if it's the unstarred one.
+%
+% The argument |#2| must be a number: any non-number text will not

+%
+% The |\partmarks| command increments a global counter, and we

+contents) to some
+location on the LaTeX search path. You're probably looking for a
+directory called <code>texmf-local</code>, or something like that.</p>
+
+<p>‘Move…to a suitable place’ is admittedly very vague. Here are some
+pointers, however:</p>
+<ul>
+<li>This can be the same location as your exam source files. This
+will work, but you'll have to do this for each directory.</li>
+<li>See the good generic advice in
+<a href="http://www.tex.ac.uk/cgi-bin/texfaq2html?label=inst-wlcf">the
+TeX FAQ</a>.</li>
+<li>Your LaTeX environment might have some hints on ‘installing new

+that.</li>
+<li>If you're on a unix-like OS, then the command <code>kpsewhich
+guexam.cls</code> will show you which class file LaTeX will use (so if
+it produces no result, that's telling you that LaTeX won't find the
+files); also <code>kpsepath tex</code> will display, in an admittedly
+very oblique form, the list of places where TeX will search.</li>
+<li>If you're using MikTeX, then the documentation on the
+‘<a href="https://miktex.org/howto/miktex-console">MikTeX console</a>’
+includes a section on ‘Registering a user-managed TEXMF root
+directory’. This rather obliquely says that you can ‘register a
+user-managed TEXMF root directory’. What that means is that (i)
+you should go to a folder such as
+<code>...\Users\<em>yourname</em>\AppData\MikTeX</code>, (ii) create a
+sequence of folders so that you end up with
+<code>...\MikTeX\texmf\tex\latex\exam-n</code>, and (iii) put the
+distributed <code>.sty</code> and <code>.clo</code> files in the
+latter folder. The directory <code>...\MikTex\texmf</code> is your

draft modes. You'll most typically have a \cs{partmarks} macro and a
\env{solution} environment for each \cs{part}, but they don't have to
match up, and you can have the entire solution at the end if you prefer.
-The \cs[1]{partmarks*}n command is almost the same, but places the
-mark indicator in a slightly different position which looks better
-when there would otherwise be a gap at the right of the page. It can

+
+The \cs{partmarks} command will most typically go at the end of a
+paragraph, but it may also appear inside an equation (that is, in
+\verb|\[...\]|; don't use \verb|$$...$$|), inside one or other
+\package{amsmath} display environments, or in a list or other
+environment. If it appears inside an environment, the indicator will
+appear at the \emph{end} of the environment, independent of where in
+the environment the command was typed (which implies that you can't
+have more than one inside an environment).
+
+The starred version is similar, but budges its indicator upwards
+a little, and is a heuristic alternative which is useful in some
+cases \emph{after} a list or display, or after a numbered equation, if the placement of the
+indicator is otherwise inaesthetic
+(if the style of the part-marks indicators happens to be such
+that the indicator may be mistaken for an equation number, then
+it would be wise to use either \cs{partmarks} or \cs{partmarks*}
+after the equation, instead). If you use \cs{partmarks*} within a
+display, you might be confronted by an error message, talking
+about \cs{eqno} in maths mode, which is even more incomprehensible
+than most \LaTeX\ messages.
+
Note that \cs{partmarks} ends a paragraph (\cs{partmarks*} doesn't): this is
probably good style, but if you insist on mid-paragraph marks, then a following
\verb|\noindent| will be useful. It's helpful to use \cs{partmarks} inside a
\env{solution} to indicate the distribution of marks -- this doesn't mess up
the mark-totalling calculation.
+You may optionally give a question number as an argument to the
+\env{question} environment: \cs[1]{begin\{question\}[n]}{markgoal}.
+In \opt{compose} mode, this simply sets the question number, but in the other
+modes, when the question file is included in a master file, this
+checks that the given number~$n$ is what would be assigned
+automatically, to help detect missing or out-of-order questions. If
+the question identifier is not a number, such as `D1', then you can
+provide that identifier here also, but in this case you must also set
+\cs{QuestionNumberChecksOff} in the question preamble.
+
+The \cs{partmarks} command has an optional argument which
+indicates the category of the question, thus `bookwork', `unseen',
+and so on. If this is present -- for example
+\cs[1]{partmarks[bookwork]}{5} -- then the category is included in the
+marks indicator.
+As you might hope, the \cs{partmarks*} command can take this
+optional argument also: \cs[1]{partmarks*[bookwork]}{5}.

+ <ul>
+ <li>The [siunitx] option is now on by default, and the
+ <code>\units</code> macro produces a one-time-per-document
+ warning that it will be removed in the next version.</li>
+ <li>Having two <code>\partmarks</code> commands in an
+ environment is now detected as an error (it was documented as an
+ error, but not checked, so the extra <code>\partmarks</code>
+ commands were simply ignored).</li>
+ </ul>
+ </h:dd>
+
+<h:dt>1.4.0-b1, 2022 August 7</h:dt><h:dd>
+ <ul>
+ <li>The class file now depends on a version of LaTeX which is at least
+ the 2020/10/01 release. This is so that we can use the current LaTeX
+ hooks mechanism.</li>
+ <li>Rework <code>\partmarks</code>: the <code>\partmarks</code>
+ indicator can now go <em>inside</em> most environments, including
+ list, quotes, unnumbered equations, and the various amsmath displays. In these
+ cases, the indicator will automatically appear at the end of the
+ environment. The starred variant of the command still exists, but
+ should rarely be necessary.</li>
+ </ul>
+ </h:dd>
+
+<h:dt>1.3.5-b1, 2022 July 11</h:dt><h:dd><ul>
+<li>Fix erroneous broken line before <code>\partmarks</code>, in
+compose mode, when a paragraph fills the last line.</li>
+<li>Fix support for STIX2 fonts in XeLaTeX and LuaLaTeX (it was
+working inaccurately before).</li>
+<li>Add an optional argument for <code>\part</code> to override part numbering.</li>
+<li>Use the <code>xcolor</code> package for colour management, instead
+of the core <code>color</code> package (the <code>xcolor</code>
+package is well-known and stable, and this means that we are
+compatible with TikZ).</li>
+<li><code>\partmarks</code> in solutions no longer gobble trailing space
+(doing so is probably right in questions, and is still the case, but
+<code>\partmarks</code> in solutions tend to be more interspersed with
+text).</li>
+<li><code>\label</code> within a <code>\part</code> now refers to the
+part number (as opposed to the question number).</li>
+<li>Avoid a ‘You can't use `\unskip' in vertical mode’ error,
+in certain circumstances.</li>
+<li>Add the <code>[siunitx]</code> option, indicating that we should
+load the <a href="https://www.ctan.org/pkg/siunitx">siunitx</a> package (default no).
+This is now preferred to the <code>\units</code> macro, and the latter will be
+removed in a forthcoming release.</li>
+<li>Renamed <code>A1.clo</code> to clearer <code>myclass.clo</code></li>
+<li>Repository moved from bitbucket to
+<a href="https://heptapod.host/nxg/exam-n">https://heptapod.host/nxg/exam-n</a>,
+when bitbucket dropped support for Mercurial.
+This means, incidentally, that links to specific issues at bitbucket
+are now broken.</li>
+<li>Bold-italic maths should now work correctly with STIX.</li>
+<li>Long <code>\partmarks</code> comments now appear as footnotes.</li>
+<li>Solutions are now set <code>\normalsize</code>.</li>
+<li>Bugfix: move definition of <code>\defaultpartmarkscategory</code>
+so it can be invoked within a <code>.clo</code> file straightforwardly.</li>
+<li>Define the <code>[uprightpi]</code> option to set <code>\pi</code>
+as an upright character, as appropriate for a constant (this is
+implemented fully only for the <code>[mtpro2]</code> and
+<code>[stix2]</code> options)..</li>
+<li>Note that the <code>\units</code> macro is likely to be deprecated
+in a forthcoming version, and replaced by a recommendation to use the
+standard <code>[siunitx]</code> package.</li>
+</ul></h:dd>
+
+<h:dt>1.3, 2018 November 21</h:dt><h:dd><ul>

+<h:dt>1.2.1, 2018 July 2</h:dt><h:dd><ul>
+<li>Bugfix: ignore any content which appears after
+<code>\end{document}</code>, in <code>\includequestion</code> (author)
+files (fixes issue 6).</li>
+<li>The environments <code>{figure*}</code> and <code>{table*}</code> now produce an error.</li>

+</ul>
+</h:dd>
+
+<h:dt>1.2, 2017 December 1</h:dt><h:dd><ul>
+<li>Use serif STIX2 fonts for sans and monospace cases, when using
+Lua- or XeLaTeX (the style doesn't use/encourage any sans-serif text,
+so this shouldn't matter).</li>
+<li>Fix font sizes in solutions.</li>
+<li>Adjustments to font-handling, which appear to have fixed LuaLaTeX differences.</li>
+<li>Add the <code>stix2</code> option, to use the
+<a href="http://www.stixfonts.org/">STIX2 font set</a>.</li>
+<li>Make it possible to use <code>\rubric</code> and <code>\baserubric</code> within a <code>.clo</code> file.

+% \begin{description}\item[1.4.0, 2022 October 10]\relax \P\thinspace The [siunitx] option is now on by default, and the
+% |\units| macro produces a one-time-per-document
+% warning that it will be removed in the next version. \P\thinspace Having two |\partmarks| commands in an
+% environment is now detected as an error (it was documented as an
+% error, but not checked, so the extra |\partmarks|
+% commands were simply ignored).\par\item[1.4.0-b1, 2022 August 7]\relax \P\thinspace The class file now depends on a version of LaTeX which is at least
+% the 2020/10/01 release. This is so that we can use the current LaTeX
+% hooks mechanism. \P\thinspace Rework |\partmarks|: the |\partmarks|
+% indicator can now go \emph{inside} most environments, including
+% list, quotes, unnumbered equations, and the various amsmath displays. In these
+% cases, the indicator will automatically appear at the end of the
+% environment. The starred variant of the command still exists, but
+% should rarely be necessary.\par\item[1.3.5-b1, 2022 July 11]\relax \P\thinspace Fix erroneous broken line before |\partmarks|, in
+% compose mode, when a paragraph fills the last line. \P\thinspace Fix support for STIX2 fonts in XeLaTeX and LuaLaTeX (it was
+% working inaccurately before). \P\thinspace Add an optional argument for |\part| to override part numbering. \P\thinspace Use the |xcolor| package for colour management, instead
+% of the core |color| package (the |xcolor|
+% package is well-known and stable, and this means that we are
+% compatible with TikZ). \P\thinspace |\partmarks| in solutions no longer gobble trailing space
+% (doing so is probably right in questions, and is still the case, but
+% |\partmarks| in solutions tend to be more interspersed with
+% text). \P\thinspace |\label| within a |\part| now refers to the
+% part number (as opposed to the question number). \P\thinspace Avoid a ‘You can't use `\unskip' in vertical mode’ error,
+% in certain circumstances. \P\thinspace Add the |[siunitx]| option, indicating that we should
+% load the siunitx\footnote{\url{https://www.ctan.org/pkg/siunitx}} package (default no).
+% This is now preferred to the |\units| macro, and the latter will be
+% removed in a forthcoming release. \P\thinspace Renamed |A1.clo| to clearer |myclass.clo| \P\thinspace Repository moved from bitbucket to
+% https://heptapod.host/nxg/exam-n\footnote{\url{https://heptapod.host/nxg/exam-n}},
+% when bitbucket dropped support for Mercurial.
+% This means, incidentally, that links to specific issues at bitbucket
+% are now broken. \P\thinspace Bold-italic maths should now work correctly with STIX. \P\thinspace Long |\partmarks| comments now appear as footnotes. \P\thinspace Solutions are now set |\normalsize|. \P\thinspace Bugfix: move definition of |\defaultpartmarkscategory|
+% so it can be invoked within a |.clo| file straightforwardly. \P\thinspace Define the |[uprightpi]| option to set |\pi|
+% as an upright character, as appropriate for a constant (this is
+% implemented fully only for the |[mtpro2]| and
+% |[stix2]| options).. \P\thinspace Note that the |\units| macro is likely to be deprecated
+% in a forthcoming version, and replaced by a recommendation to use the
+% standard |[siunitx]| package.\par\item[1.3, 2018 November 21]\relax \P\thinspace Add a ‘category’ optional argument to |\partmarks|, and
+% add |\defaultpartmarkscategory|.\par\item[1.2.1, 2018 July 2]\relax \P\thinspace Bugfix: ignore any content which appears after
+% |\end{document}|, in |\includequestion| (author)
+% files (fixes issue 6). \P\thinspace The environments |{figure*}| and |{table*}| now produce an error. \P\thinspace The macro |\vec| now produces correct greek bold maths. \P\thinspace Docmentation: notes on unit formatting.\par\item[1.2, 2017 December 1]\relax \P\thinspace Use serif STIX2 fonts for sans and monospace cases, when using
+% Lua- or XeLaTeX (the style doesn't use/encourage any sans-serif text,
+% so this shouldn't matter). \P\thinspace Fix font sizes in solutions. \P\thinspace Adjustments to font-handling, which appear to have fixed LuaLaTeX differences. \P\thinspace Add the |stix2| option, to use the
+% STIX2 font set\footnote{\url{http://www.stixfonts.org/}}. \P\thinspace Make it possible to use |\rubric| and |\baserubric| within a |.clo| file.
+% This was advertised as being possible, but it seems it had never been tested!\par\end{description} \ No newline at end of file
