De plus amples informations sont disponibles +% dans \cite{bk:lamport} et \cite{bk:GMS94}. Les options +% suppl\'ementaires qui peuvent \^etre utilis\'ees dans le pr\'eambule +% ainsi que celles qui ont un sens l\'eg\`erement diff\'erent sont +% d\'ecrites dans la table~\ref{tab+opt}. +% +% \DescribeMacro\extrarowheight +% Il y a un nouveau param\`etre, la longueur =\extrarowheight=, qui, si +% elle est positive, est ajout\'ee \`a la hauteur normale de chaque +% ligne de la table, alors que la profondeur reste la m\^eme. Ceci est +% important pour les tables comportant des lignes horizontales car +% normalement ces lignes touchent les lettres majuscules. +% Par exemple, nous avons utilis\'e =\setlength{\extrarowheight}{1pt}= +% dans la table~\ref{tab+opt}. +% +% \begin{table}[t] +% \begin{center} +% \setlength{\extrarowheight}{1pt} +% \begin{tabular}{|>{\tt}c|m{9cm}|} +% \hline +% \multicolumn{2}{|c|}{Options inchang\'ees}\\ +% \hline +% l & Colonne cadr\'ee \`a gauche. \\ +% c & Colonne centr\'ee. \\ +% r & Colonne cadr\'ee \`a droite. \\ +% p\{width\} & \'Equivalente \`a =\parbox[t]{width}=. \\ +% @\{decl.\} & Supprime l'espace entre les colonnes et le +% remplace par \texttt{decl.}. \\ +% \hline +% \multicolumn{2}{|c|}{Options nouvelles}\\ +% \hline +% m\{width\} & D\'efinit une colonne de largeur \texttt{width}. +% Chaque entr\'ee sera centr\'ee en proportion du +% reste de la ligne. Ceci est assez semblable \`a +% =\parbox{width}=. \\ +% \hline +% b\{width\} & \'Equivalente \`a =\parbox[b]{width}=. \\ +% \hline +% >\{decl.\} & Peut \^etre utilis\'ee avant une option \texttt{l}, \texttt{r}, +% \texttt{c}, \texttt{p}, \texttt{m} ou +% \texttt{b}. Ceci ins\`ere \texttt{decl.} +% directement en t\^ete de l'entr\'ee dans la colonne. \\ +% \hline +% <\{decl.\} & Peut \^etre utilis\'ee apr\`es une option \texttt{l}, \texttt{r}, +% \texttt{c}, \texttt{p}, \texttt{m} ou +% \texttt{b}. Ceci ins\`ere \texttt{decl.} +% juste apr\`es l'entr\'ee dans la colonne. \\ +% \hline +% | & Ins\`ere une ligne verticale. La distance entre +% deux colonnes sera augment\'ee de l'\'epaisseur +% de la ligne, contrairement \`a la d\'efinition +% originale de \LaTeX.\\ +% \hline +% !\{decl.\} & Peut \^etre utilis\'ee n'importe o\`u et correspond \`a l'option +% \texttt{|}. La diff\'erence est que +% \texttt{decl.} sera ins\'er\'ee \`a la place +% d'une ligne verticale, donc +% cette option ne supprime pas l'espace +% normalement ins\'er\'e entre +% les colonnes, contrairement \`a =@{...}=.\\ +% \hline +% \end{tabular} +% \end{center} +% \caption{Les options du pr\'eambule.} \label{tab+opt} +% \end{table} +% +% +% Nous allons pr\'esenter quelques exemples des nouvelles options du +% pr\'eambule. +% \begin{itemize} +% \item +% Si vous d\'esirez utiliser une fonte sp\'eciale (par exemple +% =\bfseries=) dans une colonne cadr\'ee \`a gauche, ceci peut se +% faire avec =>{\bfseries}l=. Vous n'\^etes plus oblig\'es de +% commencer chaque entr\'ee par =\bfseries=. +% \item +% Dans les colonnes qui ont \'et\'e engendr\'ees par \texttt{p}, +% \texttt{m} ou \texttt{b}, la valeur par d\'efaut de =\parindent= +% est 0pt. Ceci peut \^etre modifi\'e par:\\ +% =>{\setlength{\parindent}{1cm}}p=. +% \item +% les options \texttt{<} et \texttt{>} avaient \'et\'e +% d\'evelopp\'ees \`a l'origine pour l'application suivante: +% =>{$}c<{$}= engendre une colonne en mode math\'ematique +% dans un environnement \textsf{tabular}. Si vous utilisez ce type +% de pr\'eambule dans un environnement \textsf{array}, vous +% obtenez une colonne en mode~LR car les dollars suppl\'ementaires +% annulent ceux d\'ej\`a pr\'esents. +% \item +% Vous pouvez aussi penser \`a des applications plus complexes. Un +% probl\`eme classique peut facilement \^etre r\'esolu avec la +% s\'equence +% =>{\centerdots}c=\linebreak[0]=<{\endcenterdots}=. +% Pour centrer des nombres sur leurs points d\'ecimaux, il +% suffit\,\footnote{C'est Frank Mittelbach qui le +% dit!}~(juste~?) de d\'efinir les macros suivantes: +% \begin{verbatim} +%{\catcode`\.\active\gdef.{\egroup\setbox2\hbox\bgroup}} +%\def\centerdots{\catcode`\.\active\setbox0\hbox\bgroup} +%\def\endcenterdots{\egroup\ifvoid2 \setbox2\hbox{0}\fi +% \ifdim \wd0>\wd2 \setbox2\hbox to\wd0{\unhbox2\hfill}\else +% \setbox0\hbox to\wd2{\hfill\unhbox0}\fi +% \catcode`\.12 \box0.\box2} +%\end{verbatim} +% Attention: ces macros ne marchent pas si une cellule comporte +% plusieurs points d\'ecimaux ou si le tableau est utilis\'e en argument +% d'une autre commande. Une approche bien meilleure est d'utiliser le +% package \texttt{dcolumn.sty} \'ecrit par David Carlisle. +% \item +% En utilisant =c!{\hspace{1cm}}c= vous \'elargissez d'un +% centim\`etre l'espace entre deux colonnes, tandis que +% =c@{\hspace{1cm}}c= vous donne exactement un centim\`etre +% d'espace entre deux colonnes. +% \end{itemize} +% +% \subsection{D\'efinir de nouveaux types de colonnes} +% +% \DeleteShortVerb{\=} +% \MakeShortVerb{\"} +% \DescribeMacro{\newcolumntype} +% Alors qu'il est pratique de taper +% \begin{quote} +% ">{"\meta{quelques d\'eclarations}"}{c}<{"\meta{quelques +% autres d\'eclarations}"}" +% \end{quote} +% si vous avez une colonne particuli\`ere dans une seule table, cela +% devient peu pratique si vous utilisez souvent des colonnes de cette +% forme. La nouvelle version vous permet de d\'efinir un nouveau +% sp\'ecificateur de colonne, par exemple \texttt{x}, qui remplacera +% plusieurs commandes de sp\'ecificateurs de colonnes\footnote{Cette +% commande \'etait appel\'ee \texttt{\textbackslash{}newcolumn} dans +% \texttt{newarray.sty}. Actuellement, la commande +% \texttt{\textbackslash{}newcolumn} est toujours valide (mais affiche +% un message d'avertissement). Dans les versions ult\'erieures, elle +% dispara\^{\i}tra.}. +% Nous pouvons donc d\'efinir: +% \begin{quote} +% "\newcolumntype{x}{>{"\meta{ d\'eclarations}"}{c}<{"\meta{autres +% d\'eclarations}"}}"\hspace*{-3cm} ^^A no overfull from this line +% \end{quote} +% On peut alors utiliser le sp\'ecificateur de colonne \texttt{x} dans +% les arguments de pr\'eambule de tous les environnements \texttt{array} +% ou \texttt{tabular} dans lesquels vous d\'esirez ce format. +% +% Il est habituel d'avoir besoin de colonnes en mode math\'ematique +% et en mode~LR +% dans le m\^eme tableau. Si nous d\'efinissons: +% \begin{quote} +% "\newcolumntype{C}{>{$}c<{$}}" \\ +% "\newcolumntype{L}{>{$}l<{$}}" \\ +% "\newcolumntype{R}{>{$}r<{$}}" +% \end{quote} +% alors nous pouvons utiliser \texttt{C} pour avoir un mode~LR centr\'e +% dans un \texttt{array}, ou un mode math\'ematique centr\'e dans +% un \texttt{tabular}. +% +% L'exemple donn\'e plus haut pour les <<~points d\'ecimaux centr\'es~>> +% pourrait \^etre affect\'e \`a un sp\'ecificateur \texttt{d} par la +% commande suivante: +% \begin{quote} +% "\newcolumntype{d}{>{\centerdots}c<{\endcenterdots}}" +% \end{quote} +% +% Cette solution centre toujours le point dans la colonne. Ceci n'est +% pas tr\`es joli si la colonne est form\'ee de grands nombres, mais +% avec peu de d\'ecimales. Une autre solution d'une colonne \texttt{d} +% est: +% \begin{quote} +% "\newcolumntype{d}[1]{>{\rightdots{#1}}r<{\endrightdots}}" +% \end{quote} +% o\`u les macros ad\'equates seraient\footnote{Le package +% \texttt{dcolumn.sty} contient des commandes plus robustes bas\'ees sur +% ces id\'ees.}: +% \begin{verbatim} +% \def\coldot{.}% Ou si vous pr\'ef\'erez, \def\coldot{\cdot} +% {\catcode`\.=\active +% \gdef.{$\egroup\setbox2=\hbox to \dimen0 \bgroup$\coldot}} +% \def\rightdots#1{% +% \setbox0=\hbox{$1$}\dimen0=#1\wd0 +% \setbox0=\hbox{$\coldot$}\advance\dimen0 \wd0 +% \setbox2=\hbox to \dimen0 {}% +% \setbox0=\hbox\bgroup\mathcode`\.="8000 $} +% \def\endrightdots{$\hfil\egroup\box0\box2} +%\end{verbatim} +% Notez que "\newcolumntype" accepte le m\^eme argument optionnel que +% "\newcommand" pour d\'eclarer le nombre d'arguments pour le +% sp\'ecificateur de colonne. Maintenant vous pouvez +% sp\'ecifier "d{2}" dans votre pr\'eambule pour une colonne de +% nombres ayant au plus deux d\'ecimales. +% +% Une utilisation assez diff\'erente de "\newcolumntype" +% tire parti du fait que le texte de remplacement dans cette commande +% peut si nécessaire faire r\'ef\'erence \`a plus d'une colonne. +% Supposons maintenant que notre document contienne de nombreux +% environnements \texttt{tabular} utilisant le m\^eme pr\'eambule, +% mais que vous vouliez en essayer d'autres. La d\'efinition originale +% dans \LaTeX\ (par Leslie Lamport) vous permettait de faire (bien que +% ce soit sans doute un usage incorrect du syst\`eme): +% \begin{quote} +% "\newcommand{\X}{clr}"\\ +% "\begin{tabular}{\X}" \ldots +% \end{quote} +% \texttt{array.sty} fait bien attention de ne pas d\'evelopper le +% pr\'eambule, et donc la solution ci-dessus ne marche pas avec le +% nouveau sch\'ema.

Au contraire, avec +% \texttt{array.sty}, une table qui rentre juste dans la largeur +% \verb=\textwidth= peut produire un d\'ebordement horizontal. +% \item +% Avec le \LaTeX{} standard, modifier l'\'epaisseur des barres peut +% d\'et\'eriorer l'apparence des tables si on ne modifie pas en m\^eme +% temps les param\`etres \verb=\tabcolsep=, etc, l'espace entre la +% barre et la colonne pouvant alors devenir trop petit (ou trop +% grand). En fait, la surimpression de texte est m\^eme possible. +% Au contraire, avec \texttt{array.sty}, la modification de cette +% largeur marche souvent sans probl\`eme parce que les espaces de +% s\'eparation (comme \verb=\tabcolsep=, etc) ne d\'ependent pas de +% l'\'epaisseur des barres. +% \item +% Avec le \LaTeX{} standard, les tableaux encadr\'es pr\'esentent des +% coins bizarres parce que les barres horizontales se terminent au +% milieu des barres verticales.

Les anciennes +% versions consid\'eraient ">{"\meta{decl1}"}>{"\meta{decl2}"}" +% comme \'equivalant \`a ">{"\meta{decl1}\meta{decl2}"}". +% Cependant, cela emp\^eche l'utilisateur de remplacer les +% param\`etres d'une commande "\newcolumntype" d\'efinie en utilisant +% ces d\'eclarations. Par exemple, supposons que nous utilisons un +% sp\'ecificateur de colonne \texttt{C} (d\'efini au-dessus) dans un +% environnement \texttt{array}. Le \texttt{C} indique du texte +% centr\'e dans la colonne, alors que ">{\bfseries}C", qui est +% r\'e\'ecrit en ">{\bfseries}>{$}c<{$}" ne peut pas sp\'ecifier une +% colonne de texte en gras, parce que le pr\'eambule ressemblera en +% fait \`a "\hfil$\bfseries$#$ $\hfil" et donc le texte dans la +% colonne n'est pas affect\'e par la commande "\bfseries"\,! La +% version actuelle inverse l'ordre de ces d\'eclarations, et ainsi +% l'exemple pr\'ec\'edent fournit un pr\'eambule de la forme "\hfil$" +% "$\bfseries#$" "$\hfil", les dollars s'annulant mutuellement pour +% donner l'effet escompt\'e. +% +% \item L'utilisation de "\extracolsep" est sujette aux deux +% restrictions suivantes. Il doit y a voir au plus une commande +% "\extracolsep" par sp\'ecificateur "@" ou "!", et cette commande +% doit \^etre entr\'ee telle quelle, elle ne doit pas \^etre le +% r\'esultat du d\'eveloppement d'une commande. +% +% Ainsi, "\newcommand{\ef}{\extracolsep{\fill}}" \ldots "@{\ef}" ne +% marche pas avec ce package. Cependant, il est possible d'utiliser +% \`a la place une construction comme +% "\newcolumntype{e}{@{\extracolsep{\fill}}". +% +% \item Comme indiqu\'e dans le \LaTeX{} book, afin de d\'efinir la +% commande "\multicolumn", chaque colonne \`a l'exception de la +% premi\`ere est compos\'ee du texte compris dans la cellule et de ce +% qui se trouve dans l'espace entre les colonnes situ\'e +% \emph{apr\`es} cette colonne. Cela signifie que dans un tableau avec +% comme pr\'eambule "|l|l|l|l|", une entr\'ee telle que +% "\multicolumn{2}{|c|}" est incorrecte si elle n'intervient pas dans la +% premi\`ere colonne. +% +% Dans le \LaTeX{} standard, cette erreur n'est pas tellement visible +% parce que cette version ajoute des espaces n\'egatifs, si bien que +% chaque "|" n'occupe pas de place horizontalement. Mais dans ce +% package, les lignes verticales conservent leur \'epaisseur, on voit +% alors deux lignes si deux barres ont \'et\'e sp\'ecifi\'ees. +% \end{itemize} +% +% +% +% \changes{v2.2b}{1994/02/04}{Suppression de l'invite en mode interactif} +% +% \StopEventually{ +% +% +% \begin{thebibliography}{1} +% \bibitem{bk:GMS94} \textsc{M.~Goossens}, \textsc{F.~Mittelbach} +% et \textsc{A.~Samarin}. +% \newblock The \LaTeX{} Companion. +% \newblock +% Addison-Wesley, Reading, Massachusetts, 1994. +% \bibitem{bk:knuth} \textsc{D.

The underlying algorithm was developed by +% \textsc{Lamport} (resp.\ \textsc{Knuth}, see texhax V87\#??), and it +% has been extended and improved. +% +% The user preamble will be read \textsf{token} by \textsf{token}. A +% \textsf{token} is a single character like \texttt{c} or a block +% enclosed in ={...}=. For example the preamble of +% =\begin{tabular}=\linebreak[0]={lc||c@{\hspace{1cm}}}= consists of +% the \textsf{token} \texttt{l}, \texttt{c}, \texttt{|}, \texttt{|}, +% \texttt{@} and =\hspace{1cm}=. +% +% The currently used \textsf{token} and the one, used before, are needed +% to decide on how the construction of the preamble has to be +% continued. +% In the example mentioned above the \texttt{l} causes the preamble +% to begin with =\hskip\tabcolsep=. Furthermore +% =# \hfil= would be appended to define a flush left column. +% The next \textsf{token} is a \texttt{c}. Because it was preceded by an +% \texttt{l} it generates a new column. This is done with +% =\hskip \tabcolsep & \hskip \tabcolsep=. The column which is to +% be centered will be appended with =\hfil # \hfil=. +% The \textsf{token} \texttt{|} would then add a space of +% =\hskip \tabcolsep= +% and a vertical line because the last +% \textsf{tokens} was a \texttt{c}. +% The following \textsf{token} \texttt{|} would only add a space +% =\hskip \doublerulesep= because it was preceded by the +% \textsf{token} \texttt{|}. We will not discuss our example further but +% rather take a look at the general case of constructing preambles. +% +% The example shows that the desired preamble for the +% =\halign= can be constructed as soon as the action of all +% combinations +% of the preamble \textsf{tokens} are specified. There are 18 such +% \textsf{tokens} +% so we have $19 \cdot 18 \string= 342$ combinations if we count the +% beginning of +% the preamble as a special \textsf{token}. Fortunately, there are many +% combinations which generate the same spaces, so we can define +% \textsf{token} classes. We will identify a +% \textsf{token} within a class with a number, so we can insert the +% formatting (for example of a column). +% Table~\ref{tab+Klassen} lists all \textsf{token} classes and +% their corresponding numbers. +% \begin{table}[ht] +% \begin{center} +% \begin{tabular}[t]{>{\ttfamily}ccc} +% \textsf{token} & =\@chclass= & =\@chnum= \\[2mm] +% c & 0 & 0 \\ +% l & 0 & 1 \\ +% r & 0 & 2 \\ +% p-arg & 0 & 3 \\ +% t-arg & 0 & 4 \\ +% b-arg & 0 & 5 \\ +% | & 1 & 0 \\ +% !-arg & 1 & 1 \\ +% <-arg & 2 & --- \\ +% >-arg & 3 & --- +% \end{tabular} +% \kern3mm \vrule \kern3mm% +% \begin{tabular}[t]{>{\ttfamily}ccc} +% \textsf{token} & =\@chclass= & =\@chnum= \\[2mm] +% Start & 4 & --- \\ +% @-arg & 5 & --- \\ +% ! & 6 & --- \\ +% @ & 7 & --- \\ +% < & 8 & --- \\ +% > & 9 & --- \\ +% p & 10 & 3 \\ +% t & 10 & 4 \\ +% b & 10 & 5 +% \end{tabular} +% \end{center} +% \caption{Classes of preamble \textsf{tokens}} +% \label{tab+Klassen} +% \end{table} +% +% +% \begin{macro}{\@chclass} +% \begin{macro}{\@chnum} +% \begin{macro}{\@lastchclass} +% The class and the number of the current \textsf{token} are saved in +% the +% \textsf{count} registers =\@chclass= +% and =\@chnum=, while the class of the previous +% \textsf{token} is stored in the +% \textsf{count} register =\@lastchclass=. +% All of the mentioned registers are already allocated in +% \texttt{latex.tex}, +% which is the reason why the following three lines of code are +% commented out. +% Later throughout the text I will not mention it again explicitely +% whenever I use a =%= sign.

Nested $*$--expressions are dealt with +% correctly, that means $*$--expressions are not substituted if +% they are in explicit braces, as in =@{*}=. +% +% This macro is called via +% =\@xexpast=\meta{preamble}=*0x\@@=. +% The $*$--expression =*0x= is being used to terminate the +% recursion, +% as we shall see later, and =\@@= serves as an argument +% delimiter. =\@xexpast= has four arguments. The first +% one is the part of the +% user preamble before the first $*$--expression while the second +% and third ones are the arguments of the first $*$--expression +% (that is \textit{N} and \textit{String} in the notation mentioned +% above). +% The fourth argument is the rest of the preamble. +% \begin{macrocode} +\def\@xexpast#1*#2#3#4\@@{% +% \end{macrocode} +% The number of copies of \textit{String} (=#2=) that are to be +% produced will be saved in a \textsf{count} register. +% \begin{macrocode} + \@tempcnta #2 +% \end{macrocode} +% We save the part of the preamble which does not +% contain a $*$--form (=#1=) +% in a \PlainTeX\ \textsf{token} register. +% We also save \textit{String} (=#3=) using a \LaTeX\ +% \textsf{token} register. +% \begin{macrocode} + \toks@={#1}\@temptokena={#3}% +% \end{macrocode} +% Now we have to use a little trick to produce \textit{N} copies of +% \textit{String}. +% We could try =\def\@tempa{#1}= and then +% \textit{N} times =\edef\@tempa{\@tempa#3}=.

So we have to find a +% way to inhibit the expansion of those arguments. +% +% We will solve this problem with \textsf{token} registers. We need +% one register for every \texttt{!}\ and \texttt{@}, while we need two +% for every \texttt{c}, \texttt{l}, \texttt{r}, \texttt{m}, \texttt{p} +% or \texttt{b}. This limits the number of columns of a table because +% there are only 256 \textsf{token} registers. But then, who needs +% tables with more than 100 columns? +% +% One could also find a solution which only needs two or three +% \textsf{token} registers by proceeding similarly as in the macro +% =\@xexpast= (see page \pageref{@xexpast}). The advantage of our +% approach is the fact that we avoid some of the problems that arise +% with the other method\footnote{Maybe there are also historical +% reasons.}. +% +% So how do we proceed? Let us assume that we had =!{foo}= in the +% user preamble and say we saved \texttt{foo} in +% \textsf{token} register $5$. Then we call +% =\@addtopreamble{\the@toks5}= where +% =\the@toks= is defined in a way that it does not expand +% (for example it could be equivalent to =\relax=). Every +% following call +% of =\@addtopreamble= leaves =\the@toks5= unchanged in +% =\@preamble=. If the construction of the preamble is completed +% we change the definition of =\the@toks= to +% =\the\toks= and expand =\@preamble= for the last time. +% During this process all parts of the form +% =\the@toks=\meta{Number} +% will be substituted by the contents of the respective \textsf{token} +% registers. +% +% As we can see from this informal discussion the construction of the +% preamble has to take place within a group, so that the +% \textsf{token} registers we use will be freed later on. For that +% reason we keep all assignments to =\@preamble= global; therefore the +% replacement text of this macro will remain the same after we leave +% the group. +% +% \begin{macro}{\count@} +% We further need a \textsf{count} register to remember which +% \textsf{token} register is to be used next.

E.g.\ a =5= saved in the +% \textsf{token} register $2$ would lead \TeX\ to insert the contents +% of \textsf{token} register $15$ instead of $1$ later on. +% +% The example above referred to an older version of =\save@decl= which +% inserted a =\relex= inside the token register. This is now moved to +% the places where the actual token registers are inserted (look for +% =\the@toks=) because the old version would still make =@= +% expressions to moving arguments since after expanding the second +% register while looking for the end of the number the contents of the +% token register is added so that later on the whole register will be +% expanded. This serious bug was found after nearly two years +% international use of this package by Johannes Braams. +% \end{macro} +% +% +% +% How does the situation look like, if we want to add another column +% to the preamble, i.e.\ if we have found a \texttt{c}, \texttt{l}, +% \texttt{r}, \texttt{p}, \texttt{m} or \texttt{b} in the user +% preamble? In this case we have the problem of the \textsf{token} +% register from =>{..}= and =<{..}= having to be inserted at this +% moment because formating instructions like =\hfil= have to be set +% around them. On the other hand it is not known yet, if any =<{..}= +% instruction will appear in the user preamble at all. +% +% We solve this problem by adding two \textsf{token} registers at a +% time. This explains, why we have freed the \textsf{token} registers +% in =\prepnext@tok=. +% +% \begin{macro}{\insert@column} +% \begin{macro}{\@sharp} +% We now define the macro =\insert@column= which will do +% this work for us. +% \begin{macrocode} +\def\insert@column{% +% \end{macrocode} +% Here, we assume that the \textsf{count} register +% =\@tempcnta= has saved the value $=\count@= - 1$. +% \begin{macrocode} + \the@toks \the \@tempcnta +% \end{macrocode} +% Next follows the =#= sign which specifies the place +% where the text of the column shall be inserted.

This is to allow user +% preambles of the form, ">{foo}>{bar}..". Users are not encouraged to +% enter such expressions directly, but they may result from the +% rewriting of "\newcolumntype"'s. +% \begin{macrocode} +\def\save@decl{\toks \count@ = \expandafter\expandafter\expandafter + {\expandafter\@nextchar\the\toks\count@}} +% \end{macrocode} +% \end{macro} +% \begin{macro}{\@mkpream} +% The main modification to "\@mkpream" is to replace the call to +% "\@xexpast" (which expanded $*$-forms) by a loop which expands +% all "\newcolumntype" specifiers. +% \begin{macrocode} +\def\@mkpream#1{\gdef\@preamble{}\@lastchclass 4 \@firstamptrue + \let\@sharp\relax \let\@startpbox\relax \let\@endpbox\relax +% \end{macrocode} +% Now we remove possible $*$-forms and user-defined column +% specifiers in the user preamble by repeatedly executing the list +% "\NC@list" until the re-writes have no more effect. The +% expanded preamble will then be in the token register +% "\@temptokena". Actually we need to know at this point that +% this is not "\toks0". +% \begin{macrocode} + \@temptokena{#1}\@tempswatrue + \@whilesw\if@tempswa\fi{\@tempswafalse\the\NC@list}% +% \end{macrocode} +% Afterwards we initialize all registers and macros, that we need +% for the build-up of the preamble. +% \begin{macrocode} + \count@\m@ne + \let\the@toks\relax + \prepnext@tok +% \end{macrocode} +% Having expanded all tokens defined using "\newcolumntype" (including +% "*"), we evaluate the remaining tokens, which are saved in +% "\@temptokena".

This is allowed in +% \texttt{newarray.sty} as documented in the introduction. Removing +% the test for this case makes class 9 equivalent to class 10, and +% so this macro is redundant. It is "\let" to "\relax" to save +% space. +% \begin{macrocode} +\let\@classix\relax +% \end{macrocode} +% \end{macro} +% +% \begin{macro}{\@classviii} +% In \texttt{newarray.sty} explicitly allow class 2, as repeated +% \texttt{<} expressions are accepted by this package. +% \begin{macrocode} +\def\@classviii{\ifnum \@lastchclass >\z@\ifnum\@lastchclass=\tw@\else + \@preamerr 4\@chclass 6 \@classvi \fi\fi} +% \end{macrocode} +% \end{macro} +% +% \begin{macro}{\@classv} +% Class 5 is \texttt{@}-expressions (and is also called by class 1) +% This macro was incorrect in Version~1. Now we do not expand the +% "@"-expression, but instead explicitly replace an +% "\extracolsep" command by an assignment to "\tabskip" by a +% method similar to the "\newcolumntype" system described above. +% "\d@llarbegin" "\d@llarend" were introduced in V2.01 to match +% \texttt{array.sty} 2.0h. +% \begin{macrocode} +\def\@classv{\save@decl + \expandafter\NC@ecs\@nextchar\extracolsep{}\extracolsep\@@@ + \@addtopreamble{\d@llarbegin\the@toks\the\count@\relax\d@llarend}% + \prepnext@tok} +% \end{macrocode} +% \end{macro} +% +% \begin{macro}{\NC@ecs} +% Rewrite the first occurrence of "\extracolsep{1in}" to +% "\tabskip1in\relax".

To this end we extend the +% array parsing mechanism to include a hook which can be used by this +% (or another) package to do some additional parsing. +% +% \begin{macro}{\@tabarray} +% This macro tests for an optional bracket and then calls up +% "\@@array" or "\@@array[c]" (as default). +% \begin{macrocode} +%<*package> +\def\@tabarray{\@ifnextchar[{\@@array}{\@@array[c]}} +% \end{macrocode} +% \end{macro} +% \begin{macro}{\@@array} +% This macro tests could then test an optional delimiter before the +% left brace of the main preamble argument.
