+
+The software contained herein is a fork of Donald Arseneau wrapfig
+package. It uses most of his code, but adds a new environment,
+wraptext, to the existing wrapfigure and wraptable. In addition
+most code uses the LaTeX3 functionalities.
+
+Supposedly this software is backwards compatible with Arseneau's
+original environments. Future experience may confirm this statement.
+
+The user commands are defined by means of the LaTeX3 functionalities.
+Therefore this package does not work with LaTeX2e kernels older than about 2018, although a warning is issued if the LaTeX format file is dated with a date older than 1st January 2019.

+% \begin{abstract}
+% This new package \pack{wrapfig2} is a fork that upgrades Donald
+% Arseneau's package \pack{wrapfig} (version 2.6, dated 2003) by
+% adding some \LaTeXiii definitions that accept a final optional star;
+% its presence changes the meaning of the first optional
+% argument so that it becomes a correction to the number of lines
+% that must be indented in order to receive the wrapped object.
+% A new environment is added to the traditional \Env{wrapfigure}
+% and \Env{wraptable}, namely \Env{wraptext}; it may be used
+% to wrap a small framed text block on a grey background; the
+% philosophy of this new environment is similar to that of the
+% other two environments, but the syntax is different.
+% \end{abstract}
+%
+%^^A%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+% \paragraph{Caution} This package requires a fairly recent
+% \LaTeX kernel, otherwise it won't work; any \LaTeX kernel dated
+% at least 2020 is~OK.
+%^^A%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+%
+%^^A%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+% \section{Introduction}
+%^^A%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+%
+% The purpose of this package is twofold. On one side it tries
+% to modernise the original software by Donald Arseneau by
+% upgrading it to the \LaTeXiii modern language. On the other it
+% creates a new environment, with the same philosophy
+% of the original Arseneau's ones, such that a document author
+% can emphasise short blocks of text by framing them while
+% typesetting the text on a coloured background by means of
+% the \pack{tcolorbox} functionalities, and wrapping this
+% inserted text with the surrounding main text.
+%
+% The original software had some idiosyncrasies; Donald Arseneau
+% described them in the documentation of his package; I am sorry
+% to say that such idiosyncrasies have not been reduced; but in any case
+% the solution is to wrap the inserted object with a sufficient
+% number of lines, i.e. by a sufficiently long paragraph.
+%
+% The above implies that no wrapped object code should be inserted
+% by the end of a paragraph; again no object code should be inserted
+% within any list; not even close to the end or to the
+% beginning of section. Arseneau's code is capable of
+% specifying the wrapping number of lines such that two or more
+% paragraphs can be indented so as to wrap a longish insertion,
+% but it is wise to avoid such risky situations. Moreover, if the
+% inserted figure or table has a numbered caption, the number might
+% not result in the correct order with the normal corresponding
+% floating objects.
+%
+% Therefore the usefulness of the wrapping procedure depends very
+% much from the document author ability to move around his/her code
+% until a suitable position is found. Certainly a good place is
+% within a longish first section at the beginning of a new chapter.
+%
+% The code of this package does not do anything to correct such
+% idiosyncrasies. They are caused by the limitations of the
+% \cs{ShipOut} native \TeX/\LaTeXe macro, and very little can be done in
+% addition to what Arseneau already did.
+%
+% Another purpose of this package is to add an option so that the
+% \meta{number of indented lines} argument does not mean the total
+% number, but the correction number to add-to or subtract-from to the
+% value computed by the default mechanism devised by Arseneau. We assume
+% that any user first uses the software to insert an object to be wrapped
+% by the surrounding text without specifying any value with the
+% specific optional argument; then evaluates the result, and if the
+% space below the wrapped object is too large, or if such space is
+% too small s/he counts the necessary number of lines and specifies
+% it to be processed during another document compilation. When the
+% object to be wrapped is tall, it is very easy to miscount the
+% necessary number of lines, while is is very easy to evaluate the
+% necessary small correction to the default computed value.
+%
+% A third purpose of this package is to define a new environment,
+% \Env{wraptext}, to wrap a framed text block typeset on a grey
+% background as if it were a figure. On \texttt{texstackexchange}
+% a solution was suggested to a user who was asking for such an
+% arrangement; the solution resorted to a specific use of the
+% \Env{wrapfigure} environment. We thought that an \emph{ad hoc}
+% solution would be a better one, since the parameters to be used for a
+% figure have nothing or little to do with a text, therefore most
+% of them would be useless with a wrapped text. Nevertheless the
+% \meta{location} of the wrapped text and the optional correction
+% of the indented lines number would still be necessary. We added also
+% the possibility of optionally specifying the measure of the
+% wrapped text, even if this measure should not be too different
+% from a half of the wrapping text measure: with a value too different
+% from \texttt{0.5\cs{linewidth}} either the wrapped text has problems
+% with inter word spaces and hyphenation because of the small measure,
+% or, on the opposite, the indented lines of the wrapping text have
+% similar problems.
+%
+%^^A%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+% \section{Environment syntax}
+%^^A%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+%
+% The new syntax for \Env{wrapfigure} and \Env{wraptable} is backwards
+% compatible with the original one: just a final optional star is
+% added to the original list of arguments.
+% As the list of arguments shows, the \Env{wraptext} environment has
+% similar features, but all its arguments are optional, so that they
+% may be specified independently from one another, provided that, when
+% they are more than one, they are specified in the order
+% shown in the syntax table.
+%
+% The optional star is available only for the standard \Env{wrapfigure}
+% and \Env{wraptable} environments because the backwards compatibility
+% requires the first four optional and mandatory arguments. When the
+% optional star is specified, the \meta{indented lines number} is
+% interpreted as the correction to the computed number.

+%

+%\section{Examples}
+%^^A%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+% We display some examples by using fake objects such that suitably
+% long paragraphs are available; some fake language long paragraphs are
+% obtained by means of the \pack{kantlipsum} package functionalities.
+% They contain paragraphs that look as Kant's sentences, but we
+% doubt that Immanuel Kant ever wrote such texts\dots
+%
+%^^A%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+% \subsection{A wrapped figure}
+%^^A%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+%
+%
+%\begin{wrapfigure}{r}{50mm}*
+%\centering\unitlength=1mm
+%\begin{picture}(40,30)
+%\polygon(0,0)(40,0)(40,30)(0,30)
+%\Line(0,0)(40,30)\Line(0,30)(40,0)
+%\end{picture}
+%\caption{A rectangle}
+%\end{wrapfigure}
+%
+% \kant[1]
+%
+%
+% The code used to type the above figure is the following:
+%
+%\begin{flushleft}\obeylines%
+%\noindent\Bambiente{wrapfigure}\Marg{r}\Marg{50mm}
+%\cs{centering}\cs{unitlength}=1mm
+%\Bambiente{picture}\texttt{(40,30)}

+%\Eambiente{picture}
+%\cs{caption}\Marg{A rectangle with its diagonals}
+%\Eambiente{wrapfigure}
+%~
+%\cs{kant}\Oarg{1}
+%\end{flushleft}
+%
+% No asterisk was used because the package succeeded to correctly
+% compute the necessary number of indented lines.
+%
+%^^A%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+% \subsection{A wrapped table}
+%^^A%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+% Wrapping a small table is a little more difficult than wrapping
+% a figure, because the width of the inserted object is not known
+% exactly in advance and is difficult to estimate; therefore it is
+% possible that several trial compilations are necessary. In any
+% case a \cs{centering} command might help to center the table
+% within the indention of the wrapping text. Nevertheless the
+% software can compute the object width if a zero value is specified
+% or if the mandatory \meta{width} parameter is completely omitted;
+% this second possibility is a feature of this package, that uses a
+% \LaTeXiii property by which even a braced argument can be treated
+% as an optional argument with a predefined default value; see below
+% more details about this feature.
+%
+%\begin{wraptable}{l}
+%\centering
+% \begin{tabular}{cc}
+% \hline
+% First & Second\\
+% Third & Fourth\\
+% \hline
+%\end{tabular}
+%\caption{A small table}
+%\end{wraptable}
+%
+%\kant[2]
+%
+% The above wrapped small table has been typeset by means of the
+% following code.
+%\begin{flushleft}\ttfamily\obeylines
+%\Bambiente{wraptable}\Marg{l}
+%\quad\cs{centering}
+%\quad\Bambiente{tabular}\Marg{cc}
+%\qquad\cs{hline}
+%\qquad First \& Second\string \\
+%\qquad Third \& Fourth\string \\
+%\qquad\cs{hline}
+%\quad\Eambiente{tabular}
+%\quad\cs{caption}\Marg{A small table}
+%\Eambiente{wraptable}
+%\cs{kant}\Oarg{2}
+%\end{flushleft}
+%
+% You notice the absence of the braced width value; as said above,
+% this braced value is optional, and the software autonomously
+% computes the width of the wrapped object. This feature may be
+% useful in many instances, although we think that a smart use of
+% this width parameter might yield better looking results.
+%
+% On the opposite if the user estimates that the table with its
+% caption might use 5 lines, and specified such a value as the
+% first (optional) argument to the environment, the result would
+% be this poor one, with the last caption line overlapping the
+% wrapping text.
+%
+%\begin{wraptable}[5]{l}
+%\centering
+% \begin{tabular}{cc}
+% \hline
+% First & Second\\
+% Third & Fourth\\
+% \hline
+%\end{tabular}
+%\caption{A small table}
+%\end{wraptable}
+%\kant[2]
+%
+% If
+%
+%^^A%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+% \subsection{A wrapped text}
+%^^A%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+%
+% \begin{wraptext}
+% Text, text, text, text, text, text, text, text, text, text, text.
+% \end{wraptext}
+% \kant[3]
+%\enlargethispage{-2\baselineskip}
+%
+% The above example was typeset with this simple code:
+%\begin{flushleft}\obeylines
+% \Bamb{wraptext}
+% \ttfamily Text, text, text, text, text, text, text, text, text, text, text.
+% \Eamb{wraptext}
+% \cs{kant}[3]
+%\end{flushleft}
+%
+% As it was previously shown, the syntax for the \Env{wraptext}
+% environment is a little different from that of the other two
+% environments. The logic behind it is substantially the same;
+% the \meta{width} parameter is optional; its preset value is
+% half the column width, that in one column typesetting mode
+% coincides with the text width. The wrapped text is typeset
+% in justified mode within a \Env{minipage} environment; the
+% measure of this mini page should not be too small (unless
+% the text is less than one line long) otherwise the inter
+% word spacing might be too large; at the same time the measure
+% of the mini page cannot be too large, otherwise the indented
+% wrapping lines, generally justified, might get a bad word
+% spacing. Therefore it is suggested to avoid specifying the
+% optional \meta{widh} outside the range of 40\% to 60\% the
+% column width. Actually specifying \texttt{0.2\cs{textwidth}}
+% or \texttt{0.4\cs{columnwidth}} when typesetting in two column
+% mode produces approximately the same result, because
+% \cs{columnwidth} is a little less than half the \cs{textwidth}.
+%
+% A warning is necessary: if a caption is entered
+% within the environment, such caption gets typeset within the
+% background coloured frame. We think that a framed text does not
+% require any caption; if such caption were necessary, then the
+% user should resort to other means, for example, to a standalone
+% small PDF file containing the framed shaded text to be imported
+% as a figure with the \amb{wrapfigure} environment.
+%
+%^^A%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+% \section{Remarks}
+%^^A%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+%
+% The syntax of the original environments \amb{wrapfigure} and
+% \amb{wraptable} has not been changed, except for a last optional
+% star. The fact that the last braced argument is optional does not
+% change the backward compatibility with the original environments.
+%
+% Therefore the optional \meta{line number} argument maintains its
+% meaning, unless the optional star is specified; in such a case that
+% number assumes the meaning of a correction to the computed number
+% of the indented lines.
+%
+% The mandatory \meta{placement} maintains its meaning and the legal
+% values are \texttt{l} (left), \texttt{r} (right), \texttt{L}
+% (floating left), \texttt{R} (floating right), \texttt{i}
+% (inner margin), \texttt{o} (outer margin), \texttt{I}
+% (floating inner margin), \texttt{O} (floating outer margin).
+%
+% We tested all of them, but as a personal choice we prefer to
+% place the wrapped object at the left of the text, without
+% floating it and irrespective of the page number parity.
+%
+% As in the previous examples, we prefer to specify the wrapping
+% environment before a sufficiently long paragraph. Should the
+% paragraph be too short to completely wrap the object, all
+% the environments are capable of counting the number of indented
+% lines and to apply the \cs{overhang} command with the remaining
+% line number to the following paragraph(s); in these circumstances
+% it might be necessary to recourse to the optional star in order
+% to correct the indention, since the mechanism does not consider
+% the inter paragraph spacing that \TeX introduces only at ship~out
+% time.
+%
+% We avoid also to enter the wrapping environment before paragraphs
+% that are close to a page break; this action would tickle the
+% idiosyncrasies of the software, and requires moving the wrapping
+% environment some paragraphs before or after the preferred one; but
+% this can be done only while reviewing the document, because any
+% change in the previous source text might change the situation
+% if this adjustment is done while still editing the document.
+%
+% With the standard environments the optional parameter \meta{overhang}
+% does exactly what its name implies: the wrapped object protrudes
+% into the adjacent margin exactly by the specified amount. This
+% parameter is not available for the \Env{wraptext} environment;
+% we believe that a wrapped text logically pairs the wrapping text;
+% of course this opinion might be wrong and in future upgrades we
+% might add this functionality.
+%
+% The \meta{width} parameter has been already sufficiently described;
+% we just remember that for \Env{wraptext} this parameter is optional
+% and its default value amounts to half the current measure; it can
+% be specified but it should not be too different from 50\% the
+% current measure. For the standard environments this parameter value
+% is mandatory, but, we recall, for the redefined environments
+% \env{wrapfigure} and \env{wraptable}, this braced argument is optional.
+%
+%^^A%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+% \section{Other floating objects}
+%^^A%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+% Pictures and textual arrays may be floated by means of the standard
+% \amb{figure} and \amb{table} environments. But other floating
+% objects may be defined by means of the \pack{float} package,
+% just to name one, or classes. Besides floating, the main difference
+% is the name of the caption “label”: Figure, Table, Algorithm,
+% Example, and so on.
+%
+% If floating is not necessary, this package (as well as the original
+% one) allows to use the underlying environment \Env{wrapfloat}
+% that uses the same syntax as \Env{wrapfigure} plus the mandatory
+% name of the new object: even a figure might be introduced without
+% using \amb{wrapfigure}, by using instead:
+%\begin{flushleft}\ttfamily\obeylines
+%\Benv{wrapfloat}\Marg{figure}\oarg{line number}\marg{placement}\%
+%\quad \oarg{overhang}\marg{width}\meta{$\star$}
+%\qquad\qquad\meta{image}
+%\Eenv{wrapfloat}
+%\end{flushleft}
+% Another \meta{object} may be wrapped by using:
+%\begin{flushleft}\ttfamily\obeylines
+%\Benv{wrapfloat}\marg{object name}\oarg{line number}\marg{placement}\%

+% \section{The code}
+%^^A%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+%
+% Here we describe and comment the code of this package; essentially
+% only the initial parts need some comments; because the final ones
+% are almost identical to the original Arseneau's code.
+%
+% We start with the usual specification of the format name and date,
+% and the identification of this specific package. We possibly load
+% the \pack{etoolbox} package, because we immediately need a
+% test on the existence of an @-protected macro; should this macro
+% already been defined by the class or other packages (including a
+% previous loading of this package or the previous Arseneau's one)
+% the loading is immediately aborted. If is was not previously loaded,
+% we load the \pack{xfp} package, that allows us to perform precise
+% calculations. Loading the \pack{xparse} package is necessary in
+% order to use one of its rare features that did not migrate
+% to the \LaTeX kernel. From the \LaTeX News Letter dated October 2020:
+%\begin{quote}
+% Most, but not all, of the argument types defined by \pack{xparse}
+% are now supported at the kernel level. In particular, the types
+% \texttt{g/G}, \texttt{l} and \texttt{u} are not provided by the
+% kernel code; these are \emph{deprecated} but still available by
+% explicitly loading \pack{xparse}. All other argument types are
+% now available directly within the \LaTeXe kernel.
+%\end{quote}
+% For now their availability eases the treatment of the backwards
+% compatibility of this software with the original \pack{wrapfig}
+% functionality. It deals with the mandatory \meta{width} argument
+% of the \pack{wrapfigure}, \pack{wraptable}, and \pack{wrapfloat}
+% environments, where it was possible to specify a zero value.
+% Now it is possible to omit it completely because it is a
+% \emph{braced optional argument}.

+% Next we define some dimensions, boxes, token registers, \TeX counters,
+% and alias names. The \cs{WF at correctlines@switch} \TeX numeric register
+% (not a \LaTeX counter) is going to be used a boolean switch; if its
+% value is zero, il means “false”, otherwise is “true”; in the other
+% definitions below, it will be set only to 0 or 1, depending on the
+% presence of the optional star.

+%
+% In what follows we are going to use very often the functionalities
+% of the \pack{xparse} package that are mostly already included into
+% the \LaTeX kernel; but, since we use one of this functionalities that
+% have not migrated to the \LaTeX kernel, we load it, as they remain
+% available with that package; nevertheless we specified a
+% \LaTeX format date insuring that the \LaTeXiii syntax is available.
+%
+% Should the format file be an older one, a multitude of errors would be
+% produced, and the user should take care to load the \pack{xparse}
+% and \pack{xfp} packages before loading \pack{wrapfig2}.
+% Notice that most of the \pack{xparse} package functionalities
+% at the date required for the format file are already included. The
+% \pack{xparse} package has been available about in 2018; should the user
+% have available a definitely older \TeX system installation, s/he
+% should upgrade it, or must avoid using this \pack{wrapfig2} package
+% and use the original one; if s/he needs to wrap text, s/he should
+% resort to some ingenious tricks to do it.
+%
+% The opening command of the \Env{wrapfloat} environment receives
+% the mandatory and optional arguments plus the name of the particular
+% object to be wrapped. It is used to define the prefix label of the
+% caption number in case that the object is described with a caption. The
+% optional star is not explicit, because it is going to be read by
+% the \cs{WF at wr} macro.
+%
+% The closing command of \Env{wrapfloat} performs most of
+% the work necessary to wrap the box that contains the object
+% to be wrapped, but certain tasks are demanded to other service
+% macros.
+%
+% It may set the width of the box if the \meta{width} parameter
+% is specified; otherwise it closes the \cs{hbox} that was used;
+% then it closes the main vertical box \cs{WF at box}. After executing
+% \cs{WF at floatstyhook}, necessary when package \pack{float.sty}
+% has been used, it saves the \meta{overhang} value to be used when
+% wrapping is actually performed; then it verifies if the box height
+% is too high to fit, or is too short; possibly re-boxes this box
+% in the same box register with a negative initial vertical skip
+% that raises the box contents.
+%
+% The definitions of the \Env{wrapfigure} and \Env{wraptable}
+% environments are very simple by means of the underlaying
+% \Env{wrapfloat} environments.
+% \begin{macrocode}
+\NewDocumentEnvironment{wrapfigure}{o m o G{0pt}}%
+ {\wrapfloat{figure}[#1]{#2}[#3]{#4}}%
+ {\endwrapfloat}
+
+\NewDocumentEnvironment{wraptable}{o m o G{0pt}}%
+ {\wrapfloat{table}[#1]{#2}[#3]{#4}}%
+ {\endwrapfloat}
+
+% \end{macrocode}
+%
+% The definition of the \Env{wraptext} environment is more detailed,
+% because most of the computations must be done on the actual text
+% to be wrapped, that does not have a specific width; moreover the
+% inserted text must not be too wide, nor too short in order to avoid
+% problems for its justification or the justification of the wrapping
+% text. The framed box width is preset to 50\% of the normal text measure,
+% but it can be optionally specified to a different value (not too
+% different from 50\%), while for the other environments the wrapped
+% material width is an \emph{optional braced parameter}.
+%
+% For what concerns the \Env{wraptext} environment, see below,
+% because the code is a little more complicated and requires some
+% explanation.
+% In facts the first statement argument description list does not
+% contain any descriptor for an optional star. There is no need
+% because the computation of the insertion block height is pretty
+% precise and at most the user might desire one line more or less
+% depending on the measure of the whole text, and that of the
+% inserted block and/or the measure of the indented wrapped lines.
+%
+% It is true that some of the input parameters specified to the opening
+% command with \LaTeXiii are available also to the closing commands; see
+% the last paragraph of section~2 in the \pack{xparse} documentation.
+% But the following definition, besides using special delimiters for
+% optional parameters, uses the separate opening and closing
+% macros of the \Env{wrapfloat} environment; such procedure
+% apparently breaks this second availability of the input parameters,
+% therefore it is necessary to save them into local macros or count
+% registers (assignments of \TeX count registers are \emph{local},
+% while assignment of the \LaTeX\ named counters, through the
+% \cs{setcounter} macro and its siblings, are \emph{global}) so
+% that we can use their values within the closing commands.
+%
+% The \cs{NWF at box} has been assigned at the beginning; remember
+% that \LaTeXiii registers of any kind are not limited in number
+% as they were some years ago even with \LaTeXe.
+% The last opening commands are conceived to box the object to be
+% wrapped, typeset within a \Env{minipage} with the default or
+% specified width; such box, and the \Env{tcolorbox} and
+% \Env{minipage} environments are closed at the beginning of the
+% closing commands, so that what is necessary in order to place the
+% wrapped boxed text is easy to be executed.
+%
+% The number of indented lines is computed by means of the
+% \cs{fpeval} \LaTeXiii function; among the operands of this
+% function there is the value \texttt{2} used to take into
+% account the vertical space used by \Env{tcolorbox} to
+% separate the frame from its contents. It is possible that
+% a value of \texttt{3} might reduce the probability of using the
+% \meta{line number correction}. But it is not always true and we
+% found that the chosen value is a better choice.
+%
+% Eventually the opening \Env{wrapfloat} statement is created by
+% expanding the whole line complete of arguments, by means of the
+% usual trick of defining a dummy macro within a group that contains
+% among its expansion the group closing command, so that while
+% it is being executed, it deletes itself from memory.
+% \begin{macrocode}

+ \ignorespaces
+}
+
+% \end{macrocode}
+%
+% Now comes the definition of the fundamental environment \Env{wrapfloat};
+% compared to the original Arseneau's definition it is much longer,
+% but it contains the code that Arseneau, who wrote the code in
+% \LaTeXe language, had to split in several macros in order to
+% handle the multitude of interspersed mandatory and optional
+% arguments.
+%
+% The main function of this environment is to handle the box that
+% contains the figure, or the table, or the framed test, or what
+% else, so that the inserted box is preceded and followed by the
+% suitable vertical spaces, and it is possible to compute the
+% number of lines to be indented; often this computed number is correct;
+% but in certain cases, when the code is used too close or
+% within prohibited wrapping text, such number might need to be
+% corrected. As it can be seen the optional star is not among
+% the argument descriptors of the opening commands; it will be
+% the following macro \cs{WR at wr} to take care of examining
+% the list of arguments and see if a star has been specified and
+% not yet read by the preceding commands.
+%
+% In order to handle any kind of wrapped object, this environment
+% first argument is the \meta{caption label}. It may remain blank;
+% but for wrapping figures or tables their respective definitions
+% specify the name of the floating object they belong to; it is not
+% necessary that there exists a floating environment with the same
+% name of the wrapped object, when its wrapping environment is not
+% specified with a floating \meta{placement} argument.

+%
+% The working macro \cs{WF at wr} is defined with the \LaTeXiii
+% language; it grabs all the optional and mandatory arguments
+% in a single step, contrary to \LaTeXe that requires to split
+% the various steps in separate macros. In the definition code
+% we use also some commands, such as \cs{unless}, originally
+% defined by the \eTeX typesetting program extensions, that have
+% been included in the \pdfLaTeX, \XeLaTeX and \LuaLaTeX kernels
+% several years ago.
+%
+% Notice that the optional first (optional) argument, that represents
+% the number of indented lines or their correction number, is saved
+% into the macro \cs{WF at wli}, but if this argument is not specified,
+% \cs{WF at wli} is assigned the value zero. The same happens for the
+% \meta{overhang} optional argument.
+%
+% After these adjustments, it computes the box total height plus some
+% fixed amounts needed mostly to set the wrapped material below the
+% first wrapping text first line. Here is where the \LaTeXiii
+% \cs{fpeval} computing macro comes into play so as to assign such
+% height to \cs{WF at size}. Some unusual macros are executed; they
+% were devised by Arseneau to deal with possibly floating wrapped
+% objects. The optional star is not accepted by this macro; if the user
+% specified it, it is still in the input flux; notice that the
+% \Env{wraptext} environment does not accept the optional star; if
+% the user specifies it for this environment, an asterisk appears
+% at the beginning of the wrapped text.
+%
+% The mandatory \texttt{\#4} \meta{width} parameter (actually a
+% \meta{optional braced parameter}) may be specified
+% to be \texttt{0pt}; in any case \texttt{0pt} is the default parameter
+% value; if so, the object is treated at its natural width, by
+% boxing it into an hbox and using this hbox width as the working width

+}
+
+% \end{macrocode}
+%
+% At this point the main box \cs{WF at box} is opened in order to
+% store the object to be wrapped; with this box height the software
+% is going to compute the number of lines to be indented, unless
+% such a number has been specified and no star was added to the
+% input parameters.
+%
+% Also the \amb{wraptext} environment uses a box to collect the
+% framed text; the name of this second box must be different from
+% \cs{WF at box} otherwise interference of the various tasks produces
+% unrecoverable errors. This is why at the beginning of this
+% package we defined two different boxes: \cs{WF at box} and \cs{NWF at box}.
+%
+% The trick of creating an alias for the \cs{caption} macro is
+% used by Arseneau to redefine one of the two macros according to
+% certain conditions. Here \cs{wf at caption} is actually redefined
+% if the \meta{width} parameter has been specified.
+% \begin{macrocode}
+\def\wf at caption{\relax% redefine \wf at caption in case \hsize is zero
+ \ifdim\hsize>\z@
+ \let\caption\wf@@caption
+ \else
+ \unskip \egroup \hsize\wd\z@ \@parboxrestore \box\z@% empty \box0
+ \fi
+ \caption
+}
+
+% \end{macrocode}
+%
+% One of these unusual macros was introduced by Arseneau
+% to deal with paragraph parameters and possibly to float the
+% object to be wrapped.
+% \begin{macrocode}
+\def\WF at startfloating{%
+ \WF at everypar\expandafter{\the\everypar}\let\everypar\WF at everypar
+ \WF@@everypar{\ifvoid\WF at box\else\WF at floathand\fi \the\everypar

+}}
+
+% \end{macrocode}
+% The following macro is for floating wrapping environments.
+% \begin{macrocode}

+% Here comes the very important macro that counts the wrapping indented
+% lines, so that wrapping is correct; of course the limitations
+% of the \TeX and \LaTeX processing (needed to ship out a complete

+% paragraphs and/or those inserted between entries of various
+% listings. The idiosyncrasies of this package arise from the
+% fact that this macro cannot preview actions that have not
+% yet taken place when this macro is executed.
+%
+% This macro is the one that counts the lines to be indented by
+% rounding the division of the box height by the current base
+% line skip. Notice that \texttt{WF at wrappedlines} is the name
+% of a \LaTeX named counter, not of a \TeX numeric register;
+% therefore special LaTeX commands, such as \cs{setocounter} or
+% \cs{value}, have to be used in order to set or access the
+% numerical value stored within the \TeX register associated

+%
+% The next macro is the one that actually indents the wrapping text lines
+% and keeps track of the number of such processed lines. It can work
+% on more than a single paragraph. It resorts to service macros that
+% reiterate as long as the number of indented lines is lower than the
+% computed number of lines. Possibly this process could be defined by
+% means od the \texttt{dowhile} or \texttt{whiledo} \LaTeXiii functions.

+%
+% While this one issues a warning when a wrapping environment is
+% too close to another one.
+% \begin{macrocode}
+\def\WF at collision{\WF at warning{Collision between wrapping environments}}%
+
+% \end{macrocode}
+%
+% And this one is when two wrapping environments are too close to

+% Arseneau says that his \pack{wrapfig} package is already compatible
+% with package \pack{float.sty}, since, after defining a new float
+% \meta{foo}, it suffices to define the new environment
+% \Env{wrap\meta{foo}}. This fork version of his package should do
+% the same: is suffices to mimic the definitions of environments
+% \Env{wrapfigure} or \Env{wraptable}.
+%
+% Here there is some Arseneau's code that renders his \pack{wrapfig}
+% code compatible with \cs{newfloat} of class \class{memoir}, and
+% with \cs{newfoatlist} of package \pack{ccaption}. We leave his code
+% hereafter; but we did not test it with this package.
