+% Changelog since version 2.4:
%--------------------------------------------------------------------
-% Version 2.4, 2011/05/22:
-%
+% Version 2.5 2015/05/07
+
% No longer betatest.
-%
-%--------------------------------------------------------------------
-% Version 2.321$\beta$, 2011/05/15:
-%
-% New environments: EnvUplevel and EnvFullwidth
-%
-% The EnvUplevel environment is similar to the command \uplevel,
-% except that \uplevel is a command taking one argument. The
-% EnvUplevel environment has the advantage that you can include
-% verbatim material (using, e.g., the \verb command) in the
-% environment. (You can't include verbatim material in the argument
-% of an \uplevel command.)
-%
-% The EnvFullwidth environment is similar to the command \fullwidth,
-% except that \fullwidth is a command taking one argument. The
-% EnvFullwidth environment has the advantage that you can include
-% verbatim material (using, e.g., the \verb command) in the
-% environment. (You can't include verbatim material in the argument
-% of a \fullwidth command.)
-%
-%--------------------------------------------------------------------
-% Version 2.320$\beta$, 2011/04/16:
-%
-% New document class options: cancelspace
-% nocancelspace
-% New commands: \cancelspace
-% \nocancelspace
-%
-% Using the document class option cancelspace is equivalent to giving
-% the command \cancelspace at the beginning of the file. The default is
-% \nocancelspace. Thus, the document class option nocancelspace has no
-% effect, but is there to avoid errors if a user is confused.
-%
-% If the user uses the document class option cancelspace and if
-% solutions are not being printed, then any space that would be added by
-% an optional argument to the solution, solutionorbox, solutionorlines,
-% or solutionordottedlines environments will not be added.
-%
-% If solutions are being printed (because the user used the document
-% class option answers or gave the command \printanswers), then the
-% option cancelspace (and the command \cancelspace) will have no
-% effect.
-%
-%--------------------------------------------------------------------
-% Version 2.319$\beta$, 2011/04/11:
-%
-% We fixed an obscure bug, in which if the user gives a \qformat
-% command, in which case they shouldn't want to give a \droppoints
-% command, but they *do* give a \droppoints command, there is an
-% error (\padded@point@block undefined).
-%
-%--------------------------------------------------------------------
-% Version 2.318$\beta$, 2011/04/05:
-%
-% \qformat and \bonusqformat are now totally independent.
-% That is: \qformat doesn't affect bonus questions, and \noqformat
-% no longer cancels \bonusqformat.
-%
-% New command: \nobonusqformat
-% \nobonusqformat does for \bonusqformat what \noqformat does for
-% \qformat.
-%
-%--------------------------------------------------------------------
-% Version 2.317$\beta$, 2011/04/02:
-%
-% We changed the definition of \numcoverpages so that on the first run
-% of latex (when \exam@lastcoverpage isn't yet defined), \numcoverpages
-% will expand to
-% 0\mbox{\normalfont\bf ??}
-% instead of
-% \mbox{\normalfont\bf ??}
-% so that the construction \romannumeral\numcoverpages will not generate
-% an error on the first run of latex.
-%
-% We also made changes and corrections to comments.
-%
-%--------------------------------------------------------------------
-% Version 2.316$\beta$, 2010/12/22:
-%
-%
-% New commands:
-%
-% \pointsinrange{rangename}
-% \bonuspointsinrange{rangename}
-%
-% If `rangename' is the name of a grading range defined using
-% \begingradingrange{rangename} and \endgradingrange{rangename}, then
-% \pointsinrange{rangename} expands to the number of points in that
-% grading range and \bonuspointsinrange{rangename} expands to the number
-% of bonus points in that grading range.
-% We also changed the checkboxes and oneparcheckboxes environments so
-% that, when solutions are being printed, a \CorrectChoice will be
-% printed with \CorrectChoiceEmphasis (along with the \checkedchar
-% that marks the \CorrectChoice). This brings the behavior in line
-% with that of the choices and oneparchoices environments.
-%
%--------------------------------------------------------------------
-% Version 2.315$\beta$, 2010/12/21:
-%
+% Version 2.408$\beta$ 2013/11/17

% New commands:
%
-% \settabletotalpoints
-% \settabletotalbonuspoints
-%
-% Each of those takes one argument. After giving the command
-% \settabletotalpoints{numpoints}, any grade or point table (partial
-% or full) will list the total points as numpoints instead of the
-% actual total number of points in the table.
-%
-% After giving the command \settabletotalbonuspoints{numbonuspoints},
-% any grade or point table will list the total bonus points as
-% numbonuspoints instead of the actual total number of bonus points in
-% the table.
+% \firstqinrange{whatever}
+% \lastqinrange{whatever}
+% \numqinrange{whatever}
%
-% These commands are intended for exams in which students are asked to
-% do some subset of the problems, but not all of them, and so the
-% total number of points possible is less than the sum of the points
-% for all of the questions.
+% where ``whatever'' is the name of a grading range.
%
+% \firstqinrange{whatever} prints the number of the first question in
+% the range.
%
-% To have one of these commands affect only a single table, confine the
-% command and the \gradetable command inside of a group, as in
+% \lastqinrange{whatever} prints the number of the last question in the
+% range.
%
-% \begingroup
-% \settabletotalpoints{100}
-% \gradetable[v][questions]
-% \endgroup
+% \numqinrange{whatever} prints the number of questions in the range.
%
-% or even just
+% We changed a couple of internal command name related to grading
+% ranges. If the user defines the range `myrange', then we now use
+
+% \range@myrange@firstp
+% \range@myrange@lastp
+% \range@myrange@firstq
+% \range@myrange@lastq
%
-% \begin{center}
-% \settabletotalpoints{100}
-% \gradetable[v][questions]
-% \end{center}

+% \tbl@myrange@firstq
+% \tbl@myrange@lastq
+
%--------------------------------------------------------------------
-% Version 2.314$\beta$, 2010/12/01:
-%
-% New user command:
-%
-% \addquestionobject
-%
-% This is for when some of a question spills onto the next page, but
-% that page doesn't have any parts, subparts, subsubparts, or choices
-% beginning on theat page (which means that the \ifincomplete command
-% won't know that any of that question is on that page). If you say
-% \addquestionobject at the very end of the question, it will write a
-% questionobject to the .aux file so that \ifincomplete will work
-% correctly.
+% Version 2.407$\beta$ 2012/12/19
+
+% New environment:
%
-% New commands used only internally:
+% solutionbox
%
-% \first@questionobject
-% \questionobject@pluspagecheck
+% The solutionbox environment is different from the other solution
+% environments (solution, solutionorbox, solutionorlines,
+% solutionordottedlines, and solutionorgrid), in that
%
-% These were just to clean up some of the internal code.
+% (1) The box is always printed, whether answers are being printed
+% or not.
%
-%--------------------------------------------------------------------
-% Version 2.313$\beta$, 2010/02/18:
+% (2) The argument giving the size of the box is a required
+% argument, not an optional argument, and so it should be enclosed
+% in braces, not in brackets. It can be either a length or
+% \stretch{number}.
%
-% Bug fix: When solutions are not being printed, the solution,
-% solutionorlines, and solutionordottedlines environments disallow
-% pagebreaks before the environment, which can pull the last line of
-% the question (or part, or etc.) preceding the environment onto the
-% next page, even when leaving a rather large space before the
-% pagebreak. We insert
+% (3) We make no use of the TheSolution environment; the solutionbox
+% environment is completely freestanding.
%
-% \penalty 0
+% If answers are not being printed then only the box is printed, with
+% nothing in it. If answers are being printed, then the solution is
+% printed inside of the box.
%
-% to allow a pagebreak before the environment. We make no change to
-% the solutionorbox environment, since it didn't have this problem.
+% Note: It's the user's responsibility to be sure that the box is
+% large enough to hold the solution! If the solution takes up too
+% much vertical space, then it will spill out of the bottom of the
+% box, overwriting whatever follows the box.
%
%--------------------------------------------------------------------
-% Version 2.312$\beta$, 2010/01/17:
+% Version 2.406$\beta$, 2012/12/16
%
-% New commands:
-%
-% \combinedgradetable
-% \combinedpointtable
-% \partialcombinedgradetable
-% \partialcombinedpointtable
-%
-% These are similar to \gradetable, \pointable, \bonusgradetable,
-% \bonuspointtable, \partialgradetable, \partialpointtable,
-% \partialbonusgradetable, and \partialbonuspointtable except that
-% these new commands list both the points and the bonus points.
-%
-% \partialcombinedgradetable and \partialcombinedpointtable take one
-% required argument, which is the name of the grading range. All four
-% of these commands take two optional arguments, the first being either
-% ``v'' or ``h'' and the second being either ``questions'' or
-% ``pages''. The possibilities are thus
+% New command:
%
-% \combinedgradetable[v][questions]
-% \combinedgradetable[v][pages]
-% \combinedgradetable[h][questions]
-% \combinedgradetable[h][pages]
-% \partialcombinedgradetable{rangename}[v][questions]
-% \partialcombinedgradetable{rangename}[v][pages]
-% \partialcombinedgradetable{rangename}[h][questions]
-% \partialcombinedgradetable{rangename}[h][pages]
-%
-% The defaults are ``v'' and ``questions''.
-%
-% The horizontal tables have separate rows for the points and bonus
-% points. The vertical tables have separate columns for the points and
-% bonus points.
-%
-% The default values for the words that appear in the tables are set by
-% the commands
-%
-% \chqword{Question:}
-% \chpgword{Page:}
-% \chpword{Points:}
-% \chbpword{Bonus Points:}
-% \chsword{Score:}
-% \chtword{Total}
-% \cvqword{Question}
-% \cvpgword{Page}
-% \cvpword{Points}
-% \cvbpword{Bonus Points}
-% \cvsword{Score}
-% \cvtword{Total:}
-%
-% The words in the table can be changed by giving any of these
-% commands with the desired word as argument.
+% \noquestionsonthispage
%
-%--------------------------------------------------------------------
-% Version 2.311$\beta$, 2010/01/10:
+% This command tells the \ifcontinuation and \ifincomplete commands
+% to assume that no part of any question is on this page. This is
+% similar to the job done by the \nomorequestions command for the
+% pages that follow the end of all of the questions.
%
-% New environment: oneparcheckboxes
%
-% The oneparcheckboxes environment is to the checkboxes environment as
-% the oneparchoices environment is to the choices environment. That is,
-% each choice is begun with either a \choice or a \correctchoice
-% command, and these will all be printed as a single paragraph. When
-% answers are not being printed, each choice will have a label
-% consisting of a box that the student can check, created by the
-% argument to the last \checkboxchar command. The default value is
-% created by the command
+% If you give the command \noquestionsonthispage on a page, then
%
-% \checkboxchar{$\bigcirc$}
+% (1) \ifcontinuation on that page will expand to its second
+% argument,
+% (2) \ifincomplete on that page will expand to its second
+% argument, and
+% (3) an \ifincomplete on an earlier page will not assume that a
+% question from that earlier page continues onto this page.
%
-% (Note the dollar signs, since \bigcirc can appear only in math
-% mode.) When answers are being printed, then any choice created
-% using the \correctchoice command will be labelled by the argument to
-% the last \checkedchar command, the default value of which is created
-% by the command
+% The way that this command affects the \ifincomplete command on
+% earlier pages is as follows: If there is a page with no questions or
+% parts or subparts or subsubparts, then the last page before that
+% with a question (or part, etc.) would normally be deemed incomplete;
+% if, however, the page with no questions (or parts, etc.) (along with
+% all adjacent pages with no questions or parts etc.) has a
+% \noquestionsonthispage command, then that last page with a question
+% (or part, etc.) will not be deemed incomplete.
%
-% \checkedchar{$\surd$}
+% Note that if you're tempted to use this command on a page that follows
+% the end of all of the questions, then you should probably use the
+% command \nomorequestions instead.
%
%--------------------------------------------------------------------
-% Version 2.310$\beta$, 2010/01/09:
-%
-% New command: \bonusqformat
-%
-% The \bonusqformat command takes one argument, with the same
-% description as for the argument of the \qformat command.
+% Version 2.405$\beta$, 2012/10/21
+%
+% It is now possible to use a parts, subparts, or subsubparts
+% environment inside one of the solution environments (solution,
+% solutionorbox, solutionorlines, solutionordottedlines, or
+% solutionorgrid) without getting problems from multiply defined
+% labels or having its points (if any) counted as being actual points
+% on the exam.
+%
+% Any \part, \subpart, or \subsubpart command inside one of the
+% solution environments now writes a \PgInfo command in the .aux file
+% of the form question2@object3, but no labels and no other \PgInfo
+% commands. In addition, if there are points assigned to any of these
+% commands inside any of the solution environments, those points are
+% not added to the points of the question or the points on the page,
+% and do not affect any gradetables or pointtables.
%
-% Note added 2011/04/05: Version 2.318$\beta$ changes the behavior so
-% that \qformat and \bonusqformat are now completely independent!
-%
-% If the user gives a \qformat command, then the argument of that
-% command is used to format both questions and bonusquestions. If,
-% after giving the \qformat command, the user gives a \bonusqformat
-% command, then the argument of the \bonusqformat command will be used
-% to format bonus questions.
-%
-% Note: The \bonusqformat command must be given *after* the \qformat
-% command, or else the \bonusqformat command will have no effect.
-%
-% Note: If the user hasn't given a \qformat command, then a
-% \bonusqformat command will have no effect.
-%
-% Note: If the user gives a \qformat command and a \bonusqformat
-% command, and then later says \noqformat, then the arguments of both
-% the \qformat and \bonusqformat commands are no longer usable. That
-% is, if the user later on once again says \qformat, and wants the bonus
-% questions to have a different format from the questions, then another
-% \bonusqformat command must be given.
-%
-% Note added 2011/04/05:: The above is changed in version 2.318$\beta$.
-% \qformat and \bonusqformat are now completely independent.
-% \noqformat cancels only \qformat, and the new command
-% \nobonusqformat cancels \bonusqformat.
-%
%--------------------------------------------------------------------
-% Version 2.309$\beta$, 2009/11/30:
+% Version 2.404$\beta$, 2012/09/03
%
-% New environment: checkboxes
-% New commands: \checkboxeshook
-% \checkboxchar
-% \checkedchar
+% New command:
%
-% The checkboxes environment is similar to the choices environment,
-% except that choices are not numbered. Instead of numbers, each
-% choice has a label consisting of a box that the student can check,
-% created by the argument to the last \checkboxchar command. The
-% default value is created by the command
+% \fillwithgrid{length}
%
-% \checkboxchar{$\bigcirc$}
+% New environment:
%
-% (Note the dollar signs, since \bigcirc can appear only in math
-% mode.) When answers are being printed, then any choice created
-% using the \correctchoice command will be labelled by the argument to
-% the last \checkedchar command, the default value of which is created
-% by the command
+% solutionorgrid
%
-% \checkedchar{$\surd$}
+% These are similar to the \fillwithlines command and the
+% solutionorlines environment.
%
-% The list parameters used in the checkboxes environment can be
-% customized by redefining \checkboxeshook, the default value of which
-% is empty. (This is similar to using \choiceshook to alter the
-% choices environment.)
+% By default, the created grids are in black. However, if you give the
+% commands
%
-%--------------------------------------------------------------------
-% Version 2.308$\beta$, 2009/11/26:
+% \usepackage{color}
+% \colorgrids
%
-% We fixed a bug that caused \bonussubpart to act like \subpart and
-% \bonussubsubpart to act like \subsubpart.
+% then the grids will be in color, by default a light gray. That
+% default color was defined by the command
%
-%--------------------------------------------------------------------
-% Version 2.307$\beta$, 2009/06/11:
+% \definecolor{GridColor}{gray}{0.8}
%
-% We fixed a bug that arose only when there were cover pages and the
-% first page of the cover pages used a different extraheadheight or
-% extrafootheight from that used on the first page of the regular pages.
-% The bug caused the first page of the regular pages to use the
-% extraheadheight and extrafootheight intended only for the first cover
-% page.
+% You can change the color by redefining the color GridColor, and you
+% can return to using black grids by giving the command
%
-%--------------------------------------------------------------------
-% Version 2.306$\beta$, 2009/03/28:
+% \nocolorgrids
%
-% We fixed a bug that arose only when the user used a figure or
-% table environment that floated to the top of a page. If that
-% happened, then a full page's worth of text was placed below
-% the figure or table, makeing the text run over the footline and off
-% the bottom of the page.
+% The default grid size and grid line thickness were set by the
+% commands
%
-% We fixed this by commenting out several lines at the end of
-% \@setheadheight and @setfootheight.
+% \setlength{\gridsize}{5mm}
+% \setlength{\gridlinewidth}{0.1pt}
%
-%--------------------------------------------------------------------
-% Version 2.305$\beta$, 2009/01/30:
-%
-% We fixed a bug to keep page breaks from occurring inside of
-% \makeemptybox. We also added \begingroup \endgroup for the off
-% chance that someone was using box0 and didn't want us to change it.
-%
-% We also fixed a bug in the solutionorbox environment that showed
-% itself when the user used \stretch in the optional argument.
+% You can change either or both of those by giving new \setlength
+% commands. The period of the grid is \gridsize (both horizontally
+% and vertically). That is, the horizontal distance from the left
+% edge of one vertical line to the left edge of the next vertical line
+% is \gridsize, as is the vertical distance from the top edge of one
+% horizontal line to the top edge of the next horizontal line. Thus,
+% each square has outer side length equal to \gridsize+\gridlinewidth.
%
%--------------------------------------------------------------------
-% Version 2.304$\beta$, 2009/01/22:
-%
-% We rewrote the definition of \makeemptybox and the solutionorbox
-% environment (created in version 2.303).
-%
-% The argument to \makeemptybox can now be either a length, or \fill, or
-% \stretch{number}.
-%
-% The optional argument to the solutionorbox environment can also be
-% either a length, or \fill, or \stretch{number}. If the optional
-% argument is omitted, then no box is printed when printanswers is
-% false.
-%
-% The minimum box height is \minboxheight, whose value is set by the
-% command
+% Version 2.403$\beta$, 2012/08/29:
%
-% \setlength\minboxheight{.1in}
-%
-% This can be changed by giving a new setlength command, but it's not
-% likely that anyone actually wants a box of height less than .1 inch.
+% We changed the code for the command \fillin (which had been modified
+% in version 2.402beta) so that if only one optional argument is used,
+% a space following that optional argument will not be ignored. We
+% did this in such a way that the second optional argument will be
+% recognized even when spaces appear in between the optional
+% arguments.
%
%--------------------------------------------------------------------
-% Version 2.303$\beta$, 2009/01/21:
+% Version 2.402$\beta$, 2012/08/21:
%
-% New command: \makeemptybox
-% New environment: solutionorbox
+% We modified the command \fillin that we had created in version
+% 2.401beta. \fillin now takes two optional arguments (and no required
+% arguments).
%
-% \makeemptybox takes one argument, which is a length, and it creates
-% an empty box of width the length of the current line and of height
-% equal to the argument. That is, the box extends from the current
-% left margin (which depends on whether we're in a question, part,
-% subpart, or subsubpart) to the right margin.
-%
-% The solutionorbox environment is similar to the solution
-% environment, except that if printanswers is false and an optional
-% argument is specified, then instead of leaving that much blank space
-% we print an empty box of that height. The optional argument must be
-% a dimension; it can not be \fill. If the optional argument is
-% missing or equal to 0pt, then when printanswers is false we print
-% nothing at all.
+% \fillin can take two optional arguments, as in
%
-% Note: This is changed in version 2.304. As of that version, the
-% argument can be a length, or \fill, or \stretch{number}.
+% \fillin[Answer][Length]
%
-%--------------------------------------------------------------------
-% Version 2.302$\beta$, 2008/10/18:
+% The first optional argument is the answer to be printed above the line
+% when \printanswers is in effect; the default value is empty. That
+% line is printed a distance of \answerclearance below the baseline.
%
-% New commands: \numcoverpages and \totalnumpages
+% The second optional argument is the length of the line that we print;
+% the default value is \fillinlinelength. The value of
+% \fillinlinelength is set with the command
%
-% \numcoverpages inserts the number of pages occupied by the
-% coverpages environment. If there is no coverpages environment,
-% it inserts 0.
+% \setlength\fillinlinelength{1in}
%
-% \totalnumpages inserts the sum of \numcoverpages and \numpages.
-% Note that if there are pages preceding a coverpages environment, then
-% those pages will not be counted by \totalnumpages.
+% and can be changed by giving a new \setlength command.
%
-% We also added \relax after some \ifnum comparisons and commented
-% out some line endings to remove, e.g., an unwanted space inserted
-% by \ifcontinuation when the page is a continuation.
+% When answers are being printed, the first optional argument is
+% printed subject to the declarations in the argument of the last
+% \CorrectChoiceEmphasis command. It is centered on the line unless
+% it is too long, in which case it extends to the right of the line.
%
%--------------------------------------------------------------------
-% Version 2.301$\beta$, 2008/09/22:

+% line is printed a distance of \answerclearance below the baseline.
+%
+% The second optional argument is the length of the line that we print;

+% When answers are being printed, the optional argument is printed
+% subject to the declarations in the argument of the last

+% is too long, in which case it extends to the right of the line.
+%
+% \fillin eats (and ignores) space characters appearing before the

+

+% \fillwithgrid is similar to \fillwithlines, except that it

+% \fillwithgrid takes one argument, which is either a length or \fill

+% from the current left margin (which depends on whether we're in a

+%
+% The default grid size and grid line thickness were set by the
+% commands
+%
+% \setlength{\gridsize}{5mm}
+% \setlength{\gridlinewidth}{0.1pt}
+%
+% You can change either or both of those by giving new \setlength
+% commands. The period of the grid is \gridsize (both horizontally
+% and vertically). That is, the horizontal distance from the left
+% edge of one vertical line to the left edge of the next vertical line
+% is \gridsize, as is the vertical distance from the top edge of one
+% horizontal line to the top edge of the next horizontal line. Thus,
+% each square has outer side length equal to \gridsize+\gridlinewidth.
+
+% By default, the created grids are in black. However, if you give the
+% commands
+%
+% \usepackage{color}
+% \colorgrids
+%
+% then the grids will be in color, by default a light gray. That
