+ +\begin{minipage}[t]{0.55\linewidth} +Let's now try to draw a non-inverting amplifier based on op-amps; the canonical implementation can be, for example, \href{https://www.electronics-tutorials.ws/opamp/opamp_3.html}{this one from ``electronics tutorials''}. +Obviously, the style and form of drawing a circuit is often a matter of personal tastes and, maybe even more important, of the details you are focusing on; drawing a non-inverting amplifier will be different if you are drawing it to \emph{explain how it works} or if you are simply using it in a more complex circuit, assuming its operation well known by the reader. Anyway, the final objective is to have a circuit like the one on the right, drawn so that it is easy to reuse. +\end{minipage}\hfill +\begin{minipage}[t]{0.4\linewidth} +\begin{circuitikz}[baseline=(OA.+), ] + \ctikzset{amplifiers/fill=cyan!20, component text=left} + \draw (0,0) node[above]{$v_i$} to[short, o-] ++(1,0) + node[op amp, noinv input up, anchor=+](OA){\texttt{OA1}} + (OA.-) -- ++(0,-1) coordinate(FB) + to[R=$R_1$] ++(0,-2) node[ground]{} + (FB) to[R=$R_2$, *-] (FB -| OA.out) -- (OA.out) + to [short, *-o] ++(1,0) node[above]{$v_o$} + ; +\end{circuitikz} +\end{minipage} + +We have to start the drawing from a generic point. Given that the idea is to have a reusable block, instead of positioning the op-amp and build around it, we will start from the input ``pole'': + +\begin{LTXexample}[varwidth=true] +\begin{circuitikz}[] + \draw (0,0) node[above]{$v_i$} to[short, o-] ++(1,0) + node[op amp, noinv input up, anchor=+](OA){\texttt{OA1}} + ; +\end{circuitikz} +\end{LTXexample} + +In this snippet, notice that the only absolute coordinate is the first one; that will enable us to ``copy and paste'' the circuit in several places, or create a macro for it. We position a text node above it, and then draw a wire with a pole to a relative \texttt{(1,0)} coordinate: in other word, we \emph{move} 1~unit to the right drawing a short-circuit, which is the same as a wire. The usage of \texttt{to[short...]} simplifies the position of the pole, but notice that we could have also written: +\begin{lstlisting}[numbers=none] + \draw (0,0) node[above]{$v_i$} node[ocirc]{} -- ++(1,0) ... +\end{lstlisting} +with the same result. + +The second step is to position the op-amp. We can check the manual and see the component's description (section~\ref{sec:amplifiers}): +\begin{groupdesc} + \circuitdesc*{op amp}{Operational amplifier}{}( +/180/0.2, -/180/0.2, out/0/ +0.2, up/90/0.2, down/-90/0.2 ) +\end{groupdesc} +where we notice the type of the component (it is a node-type component, so we have to use +\texttt{node} to position it) and the available ``anchors'': points we can use to position the shape or to connect to. Not all the anchors are \emph{explicitly} printed in the description box; you should read further in the manual and you'll see a ``\emph{component} anchors'' (\ref{sec:amplifiers-anchors}) section with the relevant information. + +Anyway, the op-amp must be connected with the \texttt{+} anchor to our input wire, so we say \texttt{anchor=+} in the option lists; this shifts the whole element so that the named anchor will lie at the current position of the path. Moreover, normally the shape has the inverting input on the bottom side, and we want it the other way around, so we use also \texttt{noinv input up} in the keys defining the node. We could also have flipped the shape with \texttt{yscale=-1}, but in this case we should have considered the effects on anchors and on the text; see section~\ref{sec:mirroring-and-flipping}. + +Now we can draw the resistors; let's start with $R_1$. We will draw it going down vertically from the \texttt{-} anchor --- we have named the node \texttt{OA} so that will be \texttt{OA.-}. We will need to connect the $R_2$ also, so we do the following: +\begin{itemize} + \item draw a wire going down, and mark a point where we want the feedback resistor to connect; + \item then draw $R_1$ and finally + \item draw the ground node. +\end{itemize} + +\begin{LTXexample}[varwidth=true] +\begin{circuitikz}[scale=0.8, transform shape] + \draw (0,0) node[above]{$v_i$} to[short, o-] ++(1,0) + node[op amp, noinv input up, anchor=+](OA){\texttt{OA1}} + (OA.-) -- ++(0,-1) coordinate(FB) + to[R=$R_1$] ++(0,-2) node[ground]{} + ; +\end{circuitikz} +\end{LTXexample} + +We only miss the feedback resistor now. We will use \emph{orthogonal coordinates}, writing: +\begin{lstlisting}[numbers=none] + \draw (FB) to[R=$R_2$] (FB -| OA.out) -- (OA.out) +\end{lstlisting} + +The meaning is the following: +\begin{itemize} + \item move the current point to the coordinate named \texttt{FB}; + \item put a resistor, with label $R_2$, from here \textbf{to}\dots + \item the coordinates which is on the horizontal of \texttt{FB} and on the vertical of \texttt{OA.out}: the \texttt{-|} coordinate operation is quite mnemonic; + \item then continue drawing to \texttt{OA.out}. +\end{itemize} + +You can use a separate \verb|\draw| command or just continue the path you were writing; the choice is just personal preference, but be warned that it can affect the drawing of poles (see section~\ref{sec:bipole-nodes} about this if you notice strange things). + +Finally, we add the output and a couple of nodes: + +\begin{LTXexample}[varwidth=true] +\begin{circuitikz}[scale=0.8, transform shape] + \draw (0,0) node[above]{$v_i$} to[short, o-] ++(1,0) + node[op amp, noinv input up, anchor=+](OA){\texttt{OA1}} + (OA.-) -- ++(0,-1) coordinate(FB) + to[R=$R_1$] ++(0,-2) node[ground]{} + (FB) to[R=$R_2$, *-] (FB -| OA.out) -- (OA.out) + to [short, *-o] ++(1,0) node[above]{$v_o$} + ; +\end{circuitikz} +\end{LTXexample} + +The last step to obtain the final look is to add a bit of styling.

Style should be coherent for all the document body, so avoiding stating it for every circuit is normally the best strategy. + +\subsubsection{Reusing the circuit: the easy way} +\begingroup % to keep changes local + +The easiest way to reuse the circuit is to put it in a macro. This is a very flexible way of doing it; the only drawback is that the only easy way to position it is using the first coordinate: you will not be able to move the component using ``anchors''; that is more complex and will need the use of subcircuits (but you will loose parameters\dots see section~\ref{sec:subcircuits}). + +Defining a macro for our amplifier could be as easy as this: + +\ctikzset{amplifiers/fill=cyan!20, component text=left} +\newcommand\myNIA[4]{%1: name of this amplifier, %2 start coordinate, %3 R1, %4 R2 + \draw #2 coordinate(#1-in) to[short] ++(1,0) + node[op amp, noinv input up, anchor=+](#1-OA){\texttt{#1}} + (#1-OA.-) -- ++(0,-1) coordinate(#1-FB) + to[R=#3] ++(0,-2) node[ground]{} + (#1-FB) to[R=#4, *-] (#1-FB -| #1-OA.out) -- (#1-OA.out) + to [short, *-] ++(1,0) coordinate(#1-out) + ; +} +\begin{lstlisting} +\newcommand\myNIA[4]{%1: name of this amplifier, %2 start coordinate, %3 R1, %4 R2 + \draw #2 coordinate(#1-in) to[short] ++(1,0) + node[op amp, noinv input up, anchor=+](#1-OA){\texttt{#1}} + (#1-OA.-) -- ++(0,-1) coordinate(#1-FB) + to[R=#3] ++(0,-2) node[ground]{} + (#1-FB) to[R=#4, *-] (#1-FB -| #1-OA.out) -- (#1-OA.out) + to [short, *-] ++(1,0) coordinate(#1-out) + ; +} +\end{lstlisting} + +We remove the open poles (it's better to draw them at the end to avoid artefacts) and then we make the names of the coordinates and of the nodes unique, by prepending a parameter that we will provide at every invocation.

If +% |#7| does not match |#2|, then the optional argument is missing, we use the +% default |-NoValue-|, and put back the argument |#7| in the input stream. +% +% If it does match, then interesting things need to be done.

The hook +% \meta{code} is wrapped in the command inside a call to +% \cs{UseHook}|{cmd/|\meta{name}|/before}|, so the arguments +% passed to the command are \emph{not} available in the hook +% \meta{code}. +% +% \item[\hook{cmd/\meta{name}/after}] +% +% This hook is similar to \hook{cmd/\meta{name}/before}, but it is +% executed at the very end of the command body. This hook is +% implemented as a reversed hook. +% \end{description} +% +% The hooks are not physically present before +% \verb=\begin{document}= (i.e., using a command in the preamble +% will never execute them) and if nobody has declared any code for +% them, then they are not added to the command code ever. For +% example, if we have the following definition +%\begin{verbatim} +% \newcommand\foo[2]{Code #1 for #2!} +%\end{verbatim} +% then executing \verb=\foo{A}{B}= will simply run +% \verb*=Code A for B!= +% as it was always the case. However, if somebody, somewhere (e.g., +% in a package) adds +%\begin{verbatim} +% \AddToHook{cmd/foo/before}{<before code>} +%\end{verbatim} +% then, after |\begin{document}| the definition of \cs[no-index]{foo} will be: +%\begin{verbatim} +% \renewcommand\foo[2]{\UseHook{cmd/foo/before}Code #1 for #2!} +%\end{verbatim} +% and similarly \verb=\AddToHook{cmd/foo/after}{<after code>}= +% alters the definition to +%\begin{verbatim} +% \renewcommand\foo[2]{Code #1 for #2!\UseHook{cmd/foo/after}} +%\end{verbatim} +% +% In other words, the mechanism is similar to what \pkg{etoolbox} +% offers with \tn{pretocmd} and \tn{apptocmd} with the important +% differences +% \begin{itemize} +% \item +% +% that code can be prepended or appended (i.e., added to the +% hooks) even if the command itself is not defined, because the +% defining package has not yet been loaded +% +% \item +% +% and that by using the hook management interface it is now +% possible to define how the code chunks added in these places +% are ordered, if different packages want to add code at these +% points. +% +% \end{itemize} +% +% +% +% +% \section{Restrictions and Operational details} +% \label{sec:restrictions} +% +% Adding arbitrary material to commands is tricky because most of the +% time we do not know what the macro expects as arguments when expanding +% and \TeX{} doesn't have a reliable way to see that, so some guesswork +% has to be employed. +% +% \subsection{Patching} +% +% The code here tries to find out if a command was defined with +% \tn{newcommand} or \tn{DeclareRobustCommand} or +% \tn{NewDocumentCommand}, and if so it \emph{assumes} that the argument +% specification of the command is as expected (which is not fail-proof, +% if someone redefines the internals of these commands in devious ways, +% but is a reasonable assumption). +% +% If the command is one of the defined types, the code here does a +% sandboxed expansion of the command such that it can be redefined again +% exactly as before, but with the hook code added. +% +% If however the command is not a known type (it was defined with +% \tn{def}, for example), then the code uses an approach similar to +% \pkg{etoolbox}'s \tn{patchcmd} to retokenize the command with the hook +% code in place. This procedure, however, is more likely to fail if the +% catcode settings are not the same as the ones at the time of command's +% definition, so not always adding a hook to a command will work. +% +% \subsubsection{Timing} +% +% When \cs{AddToHook} (or its \pkg{expl3} equivalent) is called with +% a generic |cmd| hook, say, \hook{cmd/foo/before}, for the first time +% (that is, no code was added to that same hook before), in the preamble +% of a document, it will store a patch instruction for that command +% until |\begin{document}|, and only then all the commands which had +% hooks added will be patched in one go. That means that no command in +% the preamble will have hooks patched into them. +% +% At |\begin{document}| all the delayed patches will be executed, and +% if the command doesn't exist the code is still added to the hook, +% but it will not be executed. After |\begin{document}|, when +% \cs{AddToHook} is called with a generic |cmd| hook the first time, +% the command will be immediately patched to include the hook, and if +% it doesn't exist or if it can't be patched for any reason, an error +% is thrown; if \cs{AddToHook} was already used in the preamble no new +% patching is attempted. +% +% This has the consequence that a command defined or redefined after +% |\begin{document}| only uses generic |cmd| hook code if +% \cs{AddToHook} is called for the first time after the definition is +% made, or if the command explicitly uses the generic hook in its +% definition by declaring it with \cs{NewHookPair} adding \cs{UseHook} as +% part of the code.\footnote{We might change this behavior in the main +% document slightly after gaining some usage experience.} +% +% +% \subsection{Commands that look ahead} +% \label{sec:look-ahead} +% +% Some commands are defined in different ``steps'' and they look ahead +% in the input stream to find more arguments. If you try to add some +% code to the \hook{cmd/\meta{name}/after} hook of such command, it will +% not work, and it is not possible to detect that programmatically, so +% the user has to know (or find out) which commands can or cannot have +% hooks attached to them. +% +% One good example is the \tn{section} command. You can add something +% to the \hook{cmd/section/before} hook, but if you try to add something +% to the \hook{cmd/section/after} hook, \tn{section} will no longer +% work. That happens because the \tn{section} macro takes no argument, +% but instead calls a few internal \LaTeX{} macros to look for the +% optional and mandatory arguments. By adding code to the +% \hook{cmd/section/after} hook, you get in the way of that scanning. +% +% +% +% \section{Package Author Interface} +% +% The \hook{cmd} hooks are, by default, available for all commands +% that can be patched to add the hooks. For some commands, however, +% the very beginning or the very end of the code is not the best place +% to put the hooks, for example, if the command looks ahead for +% arguments (see section~\ref{sec:look-ahead}). +% +% If you are a package author and you want to add the hooks to your +% own commands in the proper position you can define the command and +% manually add the \cs{UseHook} calls inside the command in the proper +% positions, and manually define the hooks with \cs{NewHook} or +% \cs{NewReversedHook}. When the hooks are explicitly defined, +% patching is not attempted so you can make sure your command works +% properly. For example, an (admittedly not really useful) command +% that typesets its contents in a framed box with width optionally +% given in parentheses: +% \begin{verbatim} +% \newcommand\fancybox{\@ifnextchar({\@fancybox}{\@fancybox(5cm)}} +% \def\@fancybox(#1)#2{\fbox{\parbox{#1}{#2}}} +% \end{verbatim} +% If you try that definition, then add some code after it with +% \begin{verbatim} +% \AddToHook{cmd/fancybox/after}{<code>} +% \end{verbatim} +% and then use the \cs[no-index]{fancybox} command you will see that it +% will be completely broken, because the hook will get executed in the +% middle of parsing for optional \texttt{(...)} argument. +% +% If, on the other hand, you want to add hooks to your command you can +% do something like: +% \begin{verbatim} +% \newcommand\fancybox{\@ifnextchar({\@fancybox}{\@fancybox(5cm)}} +% \def\@fancybox(#1)#2{\fbox{% +% \UseHook{cmd/fancybox/before}% +% \parbox{#1}{#2}% +% \UseHook{cmd/fancybox/after}}} +% \NewHook{cmd/fancybox/before} +% \NewReversedHook{cmd/fancybox/after} +% \end{verbatim} +% then the hooks will be executed where they should and no patching +% will be attempted. It is important that the hooks are declared with +% \cs{NewHook} or \cs{NewReversedHook}, otherwise the command hook +% code will try to patch the command. Note also that the call to +% |\UseHook{cmd/fancybox/before}| does not need to be in the +% definition of \cs[no-index]{fancybox}, but anywhere it makes sense +% to insert it (in this case in the internal +% \cs[no-index]{@fancybox}). +% +% Alternatively, if for whatever reason your command does not support +% the generic hooks provided here, you can disable a hook with +% \cs{DisableHook}\footnote{Please use \cs{DisableHook} if at all, only +% on hooks that you \enquote{own}, i.e., for commands that your +% package or class defines and not second guess +% whether or not hooks of other packages should get disabled!}, so +% that when someone tries to add code to it they will get an error. +% Or if you don't want the error, you can simply declare the hook with +% \cs{NewHook} and never use it. +% +% +% The above approach is useful for really complex commands where for +% one or the other reason the hooks can't be placed at the very +% beginning and end of the command body and some hand-crafting is +% needed. However, in the example above the real (and in fact only) +% issue is the cascading argument parsing in the style developed long +% ago in \LaTeX~2.09. Thus, a much simpler solution for this case is +% to replace it with the modern \cs{NewDocumentCommand} syntax and +% define the command as follows: +% \begin{verbatim} +% \DeclareDocumentCommand\fancybox{D(){5cm}m}{\fbox{\parbox{#1}{#2}}} +% \end{verbatim} +% If you do that then both hooks automatically work and are patched +% into the right places. +% +% \StopEventually{\setlength\IndexMin{200pt} \PrintIndex } +% +% +% +% \section{The Implementation} +% +% \subsection{Execution plan} +% +% To add |before| and |after| hooks to a command we will need to peek +% into the definition of a command, which is always a tricky thing to +% do. Some cases are easy because we know how the command was defined, +% so we can assume how its \meta{parameter text} looks like (for example +% a command defined with \tn{newcommand} may have an optional argument +% followed by a run of mandatory arguments), so we can just expand that +% command and make it grab |#1|, |#2|, etc.\@ as arguments and +% define it all back with the hooks added. +% +% Life's usually not that easy, so with some commands we can't do that +% (a |#1| might as well be |#|$_{12}$|1|$_{12}$ instead of the expected +% |#|$_{6}$|1|$_{12}$, for example) so we need to resort to ``patching'' +% the command: read its \tn{meaning}, and tokenize it again with +% \tn{scantokens} and hope for the best. +% +% So the overall plan is: +% \begin{enumerate} +% \item +% Check if a command is of a known type (that is, defined with +% \tn{newcommand}\footnote{It's not always possible to reliably +% detect this case because a command defined with no optional +% argument is indistinguishable from a \tn{def}ed command.}, +% \cs[no-index]{DeclareRobustCommand}, or +% \cs[no-index]{New(Expandable)DocumentCommand}), and if is, take +% appropriate action. +% \item +% If the command is not a known type, we'll check if the command can +% be patched. Two things will prevent a command from being +% patched: if it was defined in a nonstandard catcode setting, or +% if it is an internal expl3 command with |__|\meta{module} in its +% name, in which case we refuse to patch. +% \item +% If the command was defined in nonstandard catcode settings, we +% will try a few standard ones to try our best to carry out the +% pathing. If this doesn't help either, the code will give up and +% throw an error. +% \end{enumerate} +% +% +% \begin{macrocode} +%<@@=hook> +% \end{macrocode} +% +% \changes{v1.0b}{2021/05/24}{Use \cs{msg_...} instead of \cs{__kernel_msg...}} +% +% \begin{macrocode} +%<*2ekernel|latexrelease> +\ExplSyntaxOn +%<latexrelease>\NewModuleRelease{2021/06/01}{ltcmdhooks} +%<latexrelease> {The~hook~management~system~for~commands} +% \end{macrocode} +% +% \subsection{Variables} +% +% \begin{macro}[int]{\g_hook_patch_action_list_tl} +% Pairs of |\if<cmd>..\patch<cmd>| to be used with +% \tn{robust@command@act} when looking for a known patching +% rule.

Patching by retokenization is done by +% getting the \tn{meaning} of the command, doing the necessary +% manipulations on the generated string, and the retokenizing that again +% by using \tn{scantokens}. +% +% Patching by retokenization is definitely a riskier business, because +% it relies that the tokens printed by \tn{meaning} produce the exact +% same tokens as the ones in the original definition. That is, the +% catcode régime must be exactly(ish) the same, and there is no way of +% telling except by trial and error. +% +% \begin{macro}{\@@_retokenize_patch:Nnn} +% This is the macro that will control the whole process. First we'll +% try out one final, rather trivial case, of a command with no +% arguments; that is, a token list. This case can be patched with +% the expand-and-redefine routine but it has to be the very last case +% tested for, because most (all?) robust commands start with a +% top-level macro with no arguments, so testing this first would +% short-circuit \tn{robust@command@act} and the top-level macros would +% be incorrectly patched. In that case, we just check if the +% \cs{cs_argument_spec:N} is empty, and call +% \cs{@@_patch_expand_redefine:NNnn}. +% \begin{macrocode} +\cs_new_protected:Npn \@@_retokenize_patch:Nnn #1 #2 #3 + { + \@@_patch_debug:x { ..~command~can~only~be~patched~by~rescanning } + \str_if_eq:eeTF { \cs_argument_spec:N #1 } { } + { \@@_patch_expand_redefine:NNnn \c_false_bool #1 {#2} {#3} } + { +% \end{macrocode} +% +% Otherwise, we start the actual patching by retokenization job.

As usual, more detail on individual changes +can be found in the \texttt{changes.txt} files in the distribution +and, of course, in the documented sources~\cite{33:source2e}. + + + +\section{Extending the hook concept to paragraphs} + +Largely triggered by the need for better control of paragraph text +processing, in particular when producing tagged PDF output, we have +changed \LaTeX{} so that the kernel gains control both at the start +and at the end of each paragraph. This is done in a manner that is (or +should be) transparent to both packages and documents. + +Besides the addition of internal control points for the exclusive use +of the \LaTeX{} kernel, we also implemented four public hooks that can +be used in packages or documents (via the normal hook management +declarations) to achieve special effects, etc. Until now, such +enhancements required redefinitions of \cs{everypar} or \cs{par}, +which led to the usual issues since such changes can easily conflict +with changes made by other packages. + +The documentation of these new \enquote{paragraph hooks}, together +with a few examples, is in \file{ltpara-doc.pdf} and, for those who +want to study it, the (quite interesting) code can be found in +\file{ltpara-code.pdf}. Additionally, both of these files are included +as part of the full kernel documentation in \file{source2e.pdf}. + + + +\section{Extending the hook concept to commands} + +Up to now, hook management covered hooks for only a few core areas, +such as the hooks for the \cs{shipout} process or those in the +\env{document} environment, as well as some \enquote {generic} hooks, +both for file loading (helpful for patching such files) and for +arbitrary environments (the hooks executed within \cs{begin} and +\cs{end}). This concept of \enquote{generic hooks} has now been +extended to provide \hook{/before} and \hook{/after} hooks for any +(document-level) command\Dash in theory at least. + + +In practice, these new generic \hook{cmd} hooks, especially the +\hook{cmd/.../after}, hooks may fail with commands that are too +complex to be automatically patched, breaking if the hook contains any +code. These restrictions are documented in +\texttt{ltcmdhooks-doc.pdf}. +% +However, given that these hooks are mainly meant for developers who +wish to provide better interoperability between different packages, +and between packages and the \LaTeX{} kernel, these restrictions are, +we hope, of minor importance. Indeed, for commands where this +mechanism can't be applied, one is in the same situation as before; +and for all others there will be a noticeable improvement. + +These hooks will be especially important for our current project to +provide accessible and tagged PDF output~\cite{33:blueprint} because +we will eventually have to patch many third-party packages, and this +must be done in controlled and standardized ways. + + + + +\section{Other hook business} + + +\subsection{Shipping out a page while bypassing hooks} + +In the 2020 October release, several hooks were added to control the +process of constructing and shipping out a page box: these support, +for example, the addition of background or foreground material +to some or all pages. + + +We have now added a command, called \cs{RawShipout}, which does not do +any rebuilding of the page box and so does not run most of these +hooks. When using this new command, essential internal book-keeping +is still carried out, such as updating the \texttt{totalpages} counter +and adding \texttt{shipout/firstpage} or \texttt{shipout/lastpage} +material when appropriate. + + +\subsection{A new Lua callback in \pkg{ltshipout}, +for custom attributes} + +For use just before shipping out a page, there is now a \LuaTeX{} +callback \texttt{pre\_shipout\_filter} to contain final adjustments to +the box being shipped out. This is particularly useful for +Lua\TeX\ packages which flag (using, for example, attributes or +properties) elements on a page in order to apply effects (such as the +insertion of \enquote{color commands}) to these elements at shipout. + + + +\section{Improved handling of file names} + +\subsection[File names with spaces, multiple dots or\\ + \acro{utf-8} characters] + {File names with spaces, multiple dots or \acro{utf-8} characters} + +In one of the recent \LaTeX{} releases we improved the interface +for specifying file names so that they can now safely contain spaces +(as is common these days), +more than one dot character, and also \acro{utf-8} characters +outside the \acro{ascii} range. +In the past this was only possible by applying a special syntax +in the case of spaces, +while file names with several dots often failed, +as did most \acro{utf-8} characters. + + +\subsubsection{Consequences for file names in \cs{include}} + +\TeX{} has a built-in rule saying that you can normally leave out the +extension if it is \texttt{.tex}. Thus \verb=\input{file}= and +\verb=\input{file.tex}= both load \file{file.tex} (if it exists). +While this is convenient most of the time, it is a little awkward in +some scenarios (for example, when both \file{file} and \file{file.tex} +exist) and also when you manually try to implement the rule. + +\LaTeX{} therefore had one special syntax for \cs{include} and +\cs{includeonly}: they always expected that +their arguments contain a +file name\footnote{In the case of \cs{includeonly}, a comma-separated list of such names.} +with no extension given, + so that it had to be \texttt{.tex}. Thus, + when you mistakenly wrote +\verb=\include{mychap.tex}= (for example, +because you changed from \cs{input} +to \cs{include}), +\LaTeX{} went ahead and looked for the +file \file{mychap.tex.tex} for inclusion and tried to +use the file \file{mychap.tex.aux} for internal (auxiliary) information. The reason was that +\cs{include} had to construct both +of these file names from the given +argument and it didn't bother to do +anything special +with the supplied +extension \texttt{.tex}. + +With the new implementation this has +changed: +the extension \texttt{.tex} +now gets removed/ignored if it was +supplied. +Thus \verb=\include{mychap.tex}= now +no longer looks for \file{mychap.tex.tex} +but loads +\file{mychap.tex} +and uses \file{mychap.aux}. +% +\githubissue{486} + + + +\subsection{Normalization of robust commands in file names} + +The handling of file names has been modified so that \verb|\string| is +applied to normalize robust commands within the file name. +Previously, for example, \verb|\input{\sqrt{2}}| would cause +\LaTeX\ to loop indefinitely whereas with +the new normalization +it looks for the file named \verb|sqrt {2}.tex| +(and therefore very likely reports ``file not found''). +% +\githubissue{481} + + + + +\subsection{Fix for \env{filecontents} with \acro{utf-8} + chars in the file name} + +Since a few releases back, the \env{filecontents} environment has +allowed \acro{utf-8} characters in the file name. There was, however, +a bug that would not allow \emph{over}writing a file with \acro{utf-8} +characters in its name. This has been fixed and now +\env{filecontents} allows any characters in the file name. +% +\githubissue{415} + + + +\section{Updates to the font selection scheme} + + +\subsection{A new hook in \cs{selectfont}} + +After \cs{selectfont} has changed the font, we now run a hook (\hook{selectfont}) +so that packages can make final \mbox{adjustments}. This functionality was +originally provided by the \pkg{everysel} package but our +implementation is slightly different and uses the standard hook +management. +% +\githubissue{444} + + +\subsection{Change of font series/shape delayed until \cs{selectfont}} + +With the NFSS extensions introduced in 2020, the font series and shape +settings can be influenced by changes to the font family. The +settings of these two are now therefore delayed until \cs{selectfont} +is executed; this avoids unnecessary or incorrect substitutions that +may otherwise happen due to the order of declarations. +% +\githubissue{444} + + + +\section{Glyphs, characters \& encodings} + +\subsection{Improved copy\,\&\,paste for \pdfTeX{} documents} + +When compiling with \pdfTeX{}, additional information +(from the file \texttt{glyphtounicode.tex}) is now added automatically +to the PDF file in order to improve copying from, and searching in, +text. + +In particular, this allows the most common ligatures to be copied as +intended from all generated PDF files without the need to explicitly +load the package \pkg{cmap}. +% +\githubissue{465} + + + + + +\subsection{Support for more Unicode characters} + + +\LaTeX\ is quite capable of typesetting characters such as +\enquote{\d{m}}, but until now it could not access some Unicode +characters from the Latin Extended Additional block. This meant that, +for example, there were no Unicode mappings for some characters that +are used to write Sanskrit words in Latin transliteration (as seen in +books about yoga, Buddhist philosophy, etc.). +% +These characters have now been added so that they can be entered +directly instead of using \verb=\d{m}=, etc. +% +\githubissue{484} + + + + + +\subsection{More ``dashes'' in encodings \texttt{OT1}, + \texttt{T1} and \texttt{TU}} + +When pasting in text from external sources, one can encounter these +three Unicode characters +% +\texttt{"2011} (non-breaking hyphen), +\texttt{"2012} (figure dash) and +\texttt{"2015} (horizontal bar), +% +in addition to the more common +% +\texttt{"2013} (en-dash) and \texttt{"2014} (em-dash). +% +In the past, these first three produced an error message when used +with \pdfTeX{} (since they are not available in \texttt{OT1} or +\texttt{T1} encoded fonts). They now typeset an approximation to the +glyph: e.g., the ``figure dash'' is approximated by an en-dash. + +With Unicode engines they either work (when the glyph is contained in +the selected Unicode font) or they typeset nothing, producing a +``Missing character'' warning in the log file. + +With all engines these characters can also now be accessed using the +command names \cs{textnonbreakinghyphen}, \cs{textfiguredash} and +\cs{texthorizontalbar}, respectively. +% +\githubissue{404} + + +\subsection{Poor man's \cs{textasteriskcentered}} + +The \cs{textasteriskcentered} symbol, used as part of the set of +footnote symbols in \LaTeX{}, is assumed to be implemented by every +font with the \texttt{TS1} encoding (when \pdfTeX{} is used) or with +the \texttt{TU} encoding for the Unicode engines. That assumption is +unfortunately not correct for all fonts since, for example, the +\texttt{stix2} fonts don't provide this glyph. A result is that one +gets missing glyph messages when using \cs{thanks}, etc. + +Therefore \cs{textasteriskcentered} now checks whether there is such a +glyph and, if not, uses a normal \enquote{*}, but slightly enlarged +and lowered. This may not be perfect in all cases, but it is +certainly better than no glyph showing up. +% +\githubissue{502} + +\subsection {The characters from \pkg{textcomp} are in the kernel} + +A couple of releases back, the functionality of the \pkg{textcomp} +package was integrated into the \LaTeX{} kernel. Thus it is no longer +necessary to load this package in order to access glyphs such as +\cs{textcopyright}, \cs{texteuro} or \cs{textyen}. + + +At this time the opportunity was also taken to bring some order to the +chaos surrounding the question: \enquote{which glyphs from the + \texttt{TS1} encoding are available in a given font?}. This was +done using an approach based on font families and collections, with +the differing glyph coverage of the \enquote*{text symbols} being +indicated by assigning to a font family or collection a ``sub-encoding +number'' that indicates which glyphs from the \texttt{TS1} encoding are +guaranteed to be available when using a font from that family or +collection. This assignment ensures that \LaTeX{} always errs on the +side of caution, possibly claiming that a glyph is not available even +when it in fact is. + +\iffalse %%FMi but drop that + +The documented code for this can be found now in the file +\file{lttextcomp.dtx} but we hope to publish a full explanation of +the approach very soon now. + +\fi %% FMi potential drop + + + +\subsubsection + [A note on the history of ``text symbols''] + {A note on the history of ``text symbols'' and + the \texttt{TS1} encoding} + + +The \enquote{text symbol encoding} (\texttt{TS1}) was originally +designed at the Cork Conference as a companion to the \texttt{T1} +encoding. In it various symbols that are not subject to hyphenation +got assembled and the \pkg{textcomp} package was developed to make +them accessible. Unfortunately the \TeX{} community was a bit too +enthusiastic and included several symbols only available in a few +\TeX{} fonts and some, such as the capital accents, not available at +all but developed as part of the reference font implementation. + +In hindsight that was a very bad idea because it meant that other +existing fonts (at the time) and later new fonts that got developed +were unable to provide the full set of glyphs that made up the +\texttt{TS1} encoding. For existing free PostScript fonts people +took the extra effort and produced virtual fonts that faked (some) of +the missing glyphs. But this was and is a time-consuming effort so it +was done for only a few basic fonts. But even then, only some fonts +included all glyphs from \texttt{TS1} so the \pkg{textcomp} already +back then contained a long list, dividing fonts into 5 categories +according to which glyphs were implemented and which were missing. + + +When we recently integrated the functionality of the \pkg{textcomp} +into the \LaTeX{} kernel +many new free fonts had appeared and +unfortunately the chaos around the question \enquote{which glyphs of + the \texttt{TS1} encoding are implemented by which font} had +increased with it. Not only did one find many new holes, it was next to +impossible to order the set of fonts into a reasonable set of +sub-encodings that are contained in each other in a single sequence. + +In the end we decided on nine or ten sub-encodings with a reasonable +number of fonts in each so that all fonts implemented all glyphs of the +sub-encoding they got mapped to. Thus when typesetting with a font one +could be sure that a command like \cs{textcopyleft} would either +typeset the requested character (if the glyph was part of the +sub-encoding the font belonged to) or it would raise an error, saying +that the glyph is unavailable in that font. The mapping would ensure +that \LaTeX{} always errs on the side of caution, because it might +claim a glyph is unavailable even though in fact it is.\looseness-1 + +For example, the old \texttt{pcr} (PostScript Courier) font (as well +as most other older PS fonts) is mapped to sub-encoding 5 and +therefore claims that \cs{textasciigrave} is unavailable even though +in fact for Courier this is not true. If one uses such a font and this +becomes an issue then there are a couple (suboptimal) possibilities. +For one, one can alter the mapping of Courier and pretend that belongs +to a fuller sub-encoding, e.g. +\begin{verbatim} + \DeclareEncodingSubset{TS1}{pcr}{2} +\end{verbatim} +The downside is, that \LaTeX{} then believes other glyphs that are in fact +unavailable are also there, so that it is important to check that the +final document doesn't have some missing glyphs. + +An alternative is to pretend that \cs{textasciigrave} can always be +taken from the \texttt{TS1} encoding (no questions asked): +\begin{verbatim} + \DeclareTextSymbolDefault{\textasciigrave}{TS1} +\end{verbatim} +Again there is a danger that this is not true when it is used with a +different font and would then generate a missing glyph. + +Finally, and possibly the best solution, if not impossible for other +reasons, is to simply use a different font, for example, to use the +\TeX{} Gyre Cursor font (a reimplementation of Courier with a +much more complete glyph set). + + + + +\section{New or improved commands} + +\subsection{Adjusting \env{itemize} labels with \cs{labelitemfont}} + +The command \cs{labelitemfont} was introduced already with the +\LaTeX\ release 2020-02-02, but back then we forgot to describe it, so +we do this now. Its purpose is to resolve some bad formatting issues +with the \env{itemize} environment and also to make it easier to +adjust the layout when necessary. What could happen in the past was +that the \env{itemize} labels (e.g., the \textbullet{}) would +sometimes react to surrounding font changes and could then suddenly +change shape, for example to \textit{\textbullet}. + +This new command \cs{labelitemfont}, which defaults to \cs{normalfont}, +can be used to provide additional control in the typesetting of +each label. Thus by choosing +different settings other effects can be achieved. Here are two +examples: +\begin{verbatim} + \renewcommand\labelitemfont + {\normalfont\fontfamily{lmss}\selectfont} + \renewcommand\labelitemfont + {\rmfamily\normalshape} +\end{verbatim} +The first definition will take the symbols from the font Latin Modern +Sans, so that you get +% +\def\myfont#1{{\let\labelitemfont\empty\fontfamily{lmss}\selectfont#1}}% +% +\myfont\labelitemi, \myfont\labelitemii, \myfont\labelitemiii\ and +\!\!\myfont\labelitemiv\,; while the second variant freezes the font family +and shape, but leaves the series as a variable quantity, so that an +\env{itemize} in a bold context would show bolder symbols. Making +\cs{labelitemfont} empty would give you back the buggy old behavior. +% +\githubissue{497} + + +\subsection{Producing several marks for one footnote} + +It is sometimes necessary to reference the same footnote several +times: i.e., to produce several footnote marks using the same number +or symbol. This is now easily possible by placing a \cs{label} within +the referenced \cs{footnote} and referencing this label by using the +new command \cs{footref}. This means that footnote marks can be +generated to refer to arbitrary footnotes (including those in +\texttt{minipage}s). + +This \cs{footref} command has previously been available, but only when +using certain classes or the \pkg{footmisc} package. +% +\githubissue{482} + + +\subsection{Allow \cs{nocite} in the preamble} + +A natural place for \verb=\nocite{*}= would be the preamble of the +document, but for historical reasons \LaTeX{} issued an error message +if it was placed there. This command is now allowed in the preamble. +% +\githubissue{424} + + +\subsection{Made \cs{\textbackslash} generally robust} + +In 2018 most \LaTeX{} user-level commands were made robust, including +the \cs{\textbackslash} command. However, \cs{\textbackslash} gets +redefined in various environments and not all these cases were caught: +such as, in particular, its use as the row delimiter in \env{tabular} +structures. This has been corrected so that \cs{\textbackslash} +should now be robust in all circumstances. + + +This change also fixed one anomaly present in the past: +in a tabular preamble of the form +\finalvspace*{-.3\baselineskip} +\begin{quote} + \hspace*{-.15em}\verb={l=\texttt{\string>}\verb={raggedright}p{10cm}r}= % stupid class +\end{quote} +\finalvspace*{-.3\baselineskip} +a \cs{\textbackslash} in the second column would have the definition +used within \cs{raggedright} and so it would not indicate the +(premature) end of the \env{tabular}. Thus, for example,% +\finalvspace*{-.3\baselineskip} +\begin{quote} + \verb=a & b1 \\ b2 & c \\= +\end{quote} +\finalvspace*{-.3\baselineskip} +was interpreted as a single row of the \env{tabular} (as intended), +whereas +\finalvspace*{-.3\baselineskip} +\begin{quote} + \verb=a & \\ b2 & c \\= +\end{quote} +\finalvspace*{-.3\baselineskip} +resulted in two rows! This happened because the \cs{\textbackslash} +directly following the \verb=&= got interpreted while it still had the +\enquote{end the row} meaning and not yet the \enquote{start a new + line within the second column} meaning. + +With \cs{\textbackslash} now being robust, the special scanning mode +initiated by the \verb=&= ends immediately when this command is seen: +the second column is therefore then started, which results in the +\cs{\textbackslash} being interpreted as being within that column and +hence as having its expected, within-column, meaning. + +We have restored consistency here: now both of the above lines +produce a single \env{tabular} row. +% +As before, you can +put \cs{raggedright}\cs{arraybackslash} in the \env{tabular}'s +preamble for a column to ensure that \cs{\textbackslash} is always +interpreted as a tabular row separator when used in that column. And +you can use \cs{tabularnewline} to explicitly ask for a new table row, +even when \cs{\textbackslash} has a different meaning within the +current column. +% +\githubissue{548} + + + + +\subsection{Allow extra space between name and address in \pkg{letter} class} + +The \cs{opening} command in the \pkg{letter} class expects the name +and address to be separated by \verb=\\=, but it didn't allow the use +of an optional argument to add some extra space after the name. The +code has now been slightly altered to allow this. +% +\githubissue{427} + + + +\subsection{Additions to \cs{tracingall}} + +In July 2020 David Jones suggested an extension to \TeX{} engines, +that added the possibility to set \cs{tracinglostchars}\texttt{=3} in +order to generate an error message in case some character is missing +from a font. In previous years, a warning about a missing character +was silently printed to the \texttt{.log} file\linebreak +(if $\cs{tracinglostchars}>0$) and to the terminal\linebreak + (if ${}>1$). This extension was added for \TL{} and \MiKTeX{} +(except in Knuth's \TeX, of course), +so that with $\cs{tracinglostchars}>2$ you now also get an +error message for each missing glyph. + +Later, in January 2021, Petr Olšák suggested yet another extension: +a new primitive +\mbox{parameter} +% +\cs{tracingstacklevels} that, when both it and \cs{tracingmacros} are +positive, will add to the \mbox{tracing} information for each +macro a visual indication (using dots) of +its nesting level in the macro expansion stack. + +These changes have both now been added to \LaTeX's debugging macros +\cs{tracingall} and \cs{tracingnone}, so that these two new extensions +are activated/deactivated as appropriate, so long as the \TeX{} engine +supports them. An example document demonstrating these parameters is +in the linked GitHub issue. +% +\githubissue{524} + + + + +\section{Code improvements} + +\subsection{Execute \cs{par} at the end of \cs{marginpar}} + +Previously, \LaTeX{} ended a \cs{marginpar} without ever explicitly +calling \cs{par}. This command is now explicitly added because it is +essential to the correct working of the paragraph hooks. + +Another case where this issue caused problems was the \pkg{lineno} +package, where the last line was not numbered if the \cs{marginpar} +ended without an explicit \cs{par}. +% +\githubissue{489} + + + +\subsection{Execute \cs{AtEndDocument} hook in vertical mode} + +Until now \verb=\end{document}= executed the code from the +\cs{AtEndDocument} hook as its first action. This meant that this +hook was executed in horizontal mode if the user left no empty line +after the last paragraph. As a result, one could get a spurious space +added when, for example, that code contained a \cs{write} +statement. This was fixed and now \cs{enddocument} first issues a +\cs{par} to ensure that it always goes into vertical mode. +% +\githubissue{385} + + +\subsection{Color groups made permanent} + +The use of color in certain \LaTeX{} constructs, especially boxes, +needs an extra layer of grouping to ensure that the color setting does +not \emph{escape} and continue outside the box when it shouldn't. +% +To support this, the \LaTeX{} kernel defines a number of commands, +e.g., \cs{color@begingroup} to be used in such places. + + +Until now, these commands were initially set as no-ops and only the +color packages redefined them to become real groups; this methodology +complicates the coding as one has to account for a group being present +or not (\mbox{depending} on what is loaded in the document). +% +The kernel therefore now permanently adds these \enquote{color groups}. +% +\githubissue{488} + + +\subsection{Provide the raw option list to key/value option handlers} + +Before any further processing of the option list, the original +(un-normalized, \enquote{raw} and unchanged) list of package or class +options is now saved, as \cs{@raw@opt@...}; this list is not used by +the standard option processing code but it is now available for use by +extended class/package processing systems. Note that, for +compatibility reasons, the standard option processing code has not +been changed. + + + +One +aspect of this +change does affect the standard \mbox{processing}: any tokens to the +right of an \texttt{=} +sign are \mbox{removed} +from consideration +when constructing +the \enquote{\mbox{unused} option list}. +For example, in +this release \texttt{clip=true} and +\texttt{clip=false} both contribute \texttt{clip} to the list of +options that have been used. +% +\githubissue{85} + + +\subsection{New for \pkg{latexrelease}\,: \cs{NewModuleRelease}} + +To explain the need for this new feature, we shall consider the +following example: in the 2020-10-01 release, \LaTeX's new hook +management system was added to the kernel (see \cite{33:ltnews32}) +and, as with all changes to the kernel, it was added to +\pkg{latexrelease}; this made it possible to roll back to a date where +this module didn't yet exist, or to roll forward from an older +\LaTeX{} release to get the hook management system (by loading the +\pkg{latexrelease} package). +% +However, this method of rolling back from a later release to the +2020-10-01 release didn't quite work because it would try to define +all the commands from \pkg{lthooks} again; and this would of course +result in the expected errors from commands defined with +\cs{newcommand} or (as in \pkg{lthooks}) \cs{cs\_new:Npn}. + +To solve such issues, we now provide \cs{NewModuleRelease} so that +completely new modules can be defined using the facilities of +\pkg{latexrelease} in such a way that, when rolling back or forward, +the system will know whether the code of the new module has to be read +or completely ignored. More details on this can be found in the +\pkg{latexrelease} documentation (get this with +\verb|texdoc latexrelease|). +% +\githubissue{479} + + +\subsection{Small fix for rolling back prior to 2020-02-02} + +Whereas the \pkg{latexrelease} package can usually emulate an older +\LaTeX{} kernel without much problem, rolling back to before the +2020-02-02 release didn't work properly: this is because the +management of the \cs{ExplSyntaxOn/Off} status for packages (after an +\pkg{expl3}-based package is loaded) cannot be removed by the rollback +without messing up the catcodes.

Most often this is a character, but +% there are also many commands that can be used only in horizontal mode. +% If any of them is encountered, \TeX{} will immediately back up +% (i.e., the character or command is read later again), adds a +% \cs{parskip} glue to the current vertical list unless the list is +% empty, switches to +% horizontal mode, starts its special \enquote{start of paragraph +% processing} and only then rereads the character or command that +% caused the mode change.\footnote{Already not quite true: the +% command \cs{noindent} starts the paragraph but influences the +% special processing by suppressing the paragraph indentation box +% normally inserted by it.} +% +% This \enquote{start of paragraph +% processing} first adds an empty box at the start of the +% horizontal list of width \cs{parindent} (which represents the +% paragraph indentation) unless the paragraph was started with +% \cs{noindent} in which case no such box is +% added\footnote{That's a bit different from placing a zero-sized +% box!}. It then reads and processes all tokens stored in the +% special engine token register \cs{everypar}. After that it reads +% and processes whatever has caused the paragraph to start. +% +% Thus out of the box, \TeX{} offers the possibility to put some +% special code into \cs{everypar} to gain control at (more or less) +% the start of the paragraph. For example, in LaTeX{} and a number +% of packages, special code like the following is sometimes used: +%\begin{verbatim} +% \everypar{{\setbox\z@\lastbox}\everypar{} ...} +%\end{verbatim} +% This removes the paragraph indentation box again (that was already +% placed by \TeX), then resets \cs{everypar} so that it doesn't do +% anything on the next paragraph start and then does whatever it +% wants to do, e.g., in an \cs{item} of a list it will typeset the label in +% front of the paragraph text. +% However, there is only one such \cs{everypar} token register and +% if different packages and/or the kernel all attempt to add their +% own code here, coordination is very difficult if not impossible. +% +% The process when the paragraph ends has different mechanisms and interfaces. +% A paragraph ends when the engine primitive \cs{par} is called +% while \TeX{} is in unrestricted horizontal mode, i.e., is +% building a paragraph. At other times this primitive does nothing +% or generates as an error depending on the mode \TeX{} is in, +% e.g., the \cs{par} in +% \verb=\hbox{a\par b}= is ignored, but \verb=$a\par b$= would complain. +% +% If this primitive ends the paragraph it does some special +% \enquote{end of horizontal list} processing, then calls \TeX{} paragraph +% builder that breaks the horizontal list into lines then these +% lines are added as boxes to the enclosing vertical list and +% \TeX{} returns to vertical mode. +% +% This \cs{par} command can be given explicitly, but there are also +% situations in which \TeX{} is generating it on the fly. Most +% often this happens when \TeX\ encounters a blank line which is +% automatically changed to a \cs{par} command which is then +% executed. The other possibility is that \TeX{} encounters a +% command which is incompatible with horizontal processing, e.g., +% \cs{vskip} (a request for adding vertical space). In such case it +% silently backs up, and inserts a \cs{par} in the hope that this +% gets it out of horizontal mode and makes the offending command +% acceptable. + +% The important point to note here is that \TeX{} really inserts +% the command \cs{par} which can be redefined. Thus, it may not have +% its original \enquote{primitive} meaning and therefore may not end the +% horizontal list and call the paragraph builder. This approach +% offers some flexibility but also allows you to easily produce a +% \TeX{} document that loops forever, for example, the simple line +%\begin{verbatim} +% A \let\par\relax \vskip +%\end{verbatim} +% will start a horizontal list at \texttt{A}, redefines \cs{par}, +% then sees \cs{vskip} and inserts \cs{par} to end the +% paragraph. But this now only runs \cs{relax} so nothing changes +% and \cs{vskip} is read again, issues a \cs{par} which \ldots. In +% short, it takes a plain \TeX{} document with five tokens to run +% forever (as not even memory is consumed and therefore eventually +% exhausted). +% +% There are no other ways than changing \cs{par} to gain control at +% the end of a paragraph, i.e., there is no token list like +% \cs{everypar} that is inserted, i.e., the only way to change the +% default behavior is to modify the action that \cs{par} executes +% with similar issues as outlined before: different processes need +% to ensure that they do not overwrite their modifications or +% worse, think that the \cs{par} in front of them is the engine +% primitive while in fact it has already been changed by other +% code. +% +% +% To make matters slightly worse there are a few places where +% \TeX{} handles the situation differently (most likely for speed +% reasons back when computers were much slower). If \TeX{} finds +% itself in unrestricted horizontal mode at the end of building a +% vertical box (or an \cs{insert}, \cs{vadjust} or at the end of +% executing the output routine code), it will finish the horizontal +% list not by issuing a \cs{par} command (which would be consistent +% with all other places, but by simply executing the primitive version +% of \cs{par} regardless of the definition that \cs{par} has at the +% time. +% +% Thus, if you have carefully crafted a redefined \cs{par} to execute +% some special actions at the end of a paragraph and you write +% something like +%\begin{verbatim} +% \vbox{Some paragraph ... text.} +%\end{verbatim} +% you will find that your code has never run for the last paragraph +% in that box. \LaTeX{} avoids this problem, by making sure that +% all its boxes (such as \cs{parbox} or the \env{minipage} +% environment, etc.) all internally add an explicit \cs{par} at the +% end so that such code is run and \TeX{} finds itself in vertical +% mode already without the need to start up the paragraph builder +% internally. But, of course, this only works for boxes under direct +% control of the \LaTeX{} kernel, if some package uses low-level +% \cs{vbox}es without adding this precaution the \TeX{} +% optimization kicks in and no special \cs{par} code is executed. +% +% And there is another optimization that is painful: if a paragraph +% is interrupted by a mathematical display, e.g., \verb=\[...\]= in +% \LaTeX{} or \verb=$$...$$= in plain \TeX{}, then \TeX{} will +% resume horizontal mode afterward, i.e., build a new horizontal +% list (without inserting an indentation box or \cs{everypar} at +% that point). However, if that list immediately ends with an +% explicit or implicit \cs{par} then \TeX{} will simply throw away +% this \enquote{null} paragraph and not do its usual \enquote{end +% of horizontal list} processing, so this special case need to be +% accounted for when introducing some extended processing. +% +% +% +% \section{The new mechanism implemented for \LaTeX{}} +% +% To improve the situation (and also to support automatic tagging +% of PDF documents) we now offer public as well as private hooks at +% the start and end of the paragraph processing. The public hooks +% can be used by packages (or by the user in the preamble or +% within the document) and using the hook mechanisms it is possible +% to reorder or arrange code from different packages in a way that +% it can safely coexist. +% +% To make that happen we have to make use of the basic +% functionality that is offered by \TeX{}, e.g., we install +% special code inside \cs{everypar} to provide hooks at the +% beginning and we redefine \cs{par} to do some special processing +% when appropriate to install hooks at the end of the paragraph. +% +% In order to make this work, we have to ensure that package use of +% \cs{everypar} is not overwriting our code. This is done through a +% trick: we basically hide the real \cs{everypar} from the packages +% and offer them a new token register (with the same name). So if +% they install their own code it doesn't overwrite ours. Our code +% then inserts the new \cs{everypar} at the right place inside the +% process so that it looks as if it was the primitive +% \cs{everypar}.\footnote{Ideally, \cs{everypar} wouldn't be used +% at all by packages and instead they would simply write their code +% into the hooks now offered by the kernel. However, while this is +% the longterm goal and clearly an improvement (because then the +% packages do no longer need to worry about getting their code +% overwritten or needing to account for already existing code in +% \cs{everypar}), this will not happen overnight. For that reason +% support for this legacy method is retained.} +% +% At the end of the paragraph it would be great if we could use a +% similar trick. However, due to the fact that \TeX{} inserts the +% token \cs{par} (that doesn't have a defined meaning) we can't hide +% \enquote{the real thing\textsuperscript{TM}} and offer the +% package an indistinguishable alternate. +% +% Fortunately, \LaTeX{} has already redefined \cs{par} for its own +% purposes. As a result there aren't many packages that attempt to +% change \cs{par}, because without a lot of extra care that would +% fail miserably. But bottom line, if you load a package that +% alters \cs{par} then the end of paragraph hooks are most likely +% not executing while that redefinition is +% active.\footnote{Similarly to the \cs{everypar} situation, the +% remedy is that such packages stop doing this and instead add +% their alterations into the paragraph hooks now provided.} +% +% +% +% \subsection{The provided hooks} +% +% +% \begin{variable}{para/before, +% para/begin, +% para/end, +% para/after +% } +% The following four public hooks are defined and executed for +% each paragraph: +% \begin{description} +% +% \item[\hook{para/before}] +% +% This hook is executed after the kernel hook +% \cs{@kernel@before@para@before} (discussed below) in vertical +% mode immediately after \TeX{} has contributed \cs{parskip} to +% the vertical list and before the actual paragraph processing in +% horizontal mode starts. +% +% This hook should either not produce any typeset material or add +% only vertical material. If it starts a paragraph an error is +% generated. The reason is that we are in the starting process of +% processing a paragraph and so this would lead to endless +% recursion.\footnote{One could allow it but only if the newly +% started paragraph is processed without any hooks. Furthermore +% correct spacing would be a bit of a nightmare so for now this +% is forbidden.} +% +% \end{description} +% \end{variable} +% +% \vspace{-\bigskipamount} +% +% \begin{description} +% +% \item[\hook{para/begin}] +% +% This hook is executed after the kernel hook +% \cs{@kernel@before@para@begin} (discussed below) in horizontal +% mode immediately before the indentation box is placed (if there +% is any, i.e., if the paragraph hasn't been started with +% \cs{noindent}). +% +% The indentation box to be typeset is available to the hook as +% \cs{IndentBox} and its automatic placement (after the hook is +% executed) can be prevented through \cs{OmitIndent}. +% More precisely \cs{OmitIndent} voids the box. +% +% The indentation box is then typeset directly +% after the hook execution by something equivalent to +% \cs{box}\cs{IndentBox} followed by the current content of +% the token register \cs{everypar} that it is available to the +% kernel or to packages (that run some legacy code). +% +% One has to be careful not to add any code to the hook that +% starts its own paragraph (e.g., by adding a \cs{parbox} or a +% \cs{marginpar} inside) because that would call the hook inside +% again (as a new paragraph is started there) and thus lead to an +% endless recursion ending only after exhausting the available +% memory. This can only be done by making sure that is not +% executed for the inner paragraphs (or at least not recursively +% forever). +% +% +% \item[\hook{para/end}] +% +% This hook is executed at the end of a paragraph when \TeX{} is +% ready to return to vertical mode and after it has removed the +% last horizontal glue (but not kern) placed on the horizontal +% list. The code is still executed in horizontal mode so it is +% possible to add further horizontal material at this point, but +% it should not alter the mode (even a temporary exit from +% horizontal mode would create chaos---any attempt will cause an +% error message)! After the hook has ended the kernel hook +% \cs{@kernel@after@para@end} is executed and then \TeX{} returns to +% vertical mode. +% +% The hook is offered as public hook, but because of the +% requirement to stay within horizontal mode one needs to be +% careful in what is placed into the hook.\footnote{Maybe we +% should guard against that, but it would be rather tricky to +% implement as mode changes can happen across group boundaries so +% one would need to keep a private stack just for that. Well, +% something to ponder.} +% +% This hook is implemented as a reversed hook. +% +% \item[\hook{para/after}] +% +% This hook is executed directly after \TeX{} has returned to +% vertical mode and after any material that migrated out of the +% horizontal list (e.g., from a \cs{vadjust}) has processed. +% +% This hook should either not produce any typeset material or add +% only vertical material. +% However, for this hook starting a new paragraph is not a +% disaster so that it isn't prevented. +% +% This hook is implemented as a reversed hook. +% +% Once that hook code has been processed the kernel hook +% \cs{@kernel@after@para@after} is executed as the final action +% of the paragraph processing. +% +% \end{description} +% +% \begin{variable}{\@kernel@before@para@before, +% \@kernel@after@para@after, +% \@kernel@before@para@begin, +% \@kernel@after@para@end, +% } +% As already mentioned above there are also four kernel hooks that +% are executed at the start and end of the processing. +% \begin{description} +% +% \item[\cs{@kernel@before@para@before}] +% For future extensions, not currently used by the kernel. +% +% +% \item[\cs{@kernel@after@para@after}] +% For future extensions, not currently used by the kernel. +% +% +% \item[\cs{@kernel@before@para@begin}] +% +% Used by the kernel to implement tagging. This hook is executed +% at the very beginning of a paragraph after \TeX{} has switched to +% horizontal mode but before any indentation box got added or any +% \cs{everypar} was run. +% +% It should not generate typeset material that could alter the +% position. Note that it should never leave hmode, otherwise you +% will end with a loop! We could guard against this, but since it +% is an internal kernel hook that shouldn't be touched this isn't +% checked. +% \end{description} +% \end{variable} +% +% \vspace{-\bigskipamount} +% +% \begin{description} +% +% \item[\cs{@kernel@after@para@end}] +% +% Used by the kernel to implement tagging. It is executed +% directly after the public \hook{para/end} hook. After it there +% is a quick check that we are still in horizontal mode, i.e., +% that the public hook has not mistakenly ended horizontal mode +% prematurely (this is an incomplete check just testing the mode +% and could perhaps be improved (at the cost of speed)). +% +% \end{description} +% +% +% \subsection{Altered and newly provided commands} +% +% \begin{function}{\par,\endgraf,\para_end:} +% An explicit request for ending a paragraph is known in plain +% \TeX{} under the name \cs{endgraf} where it simply calls the +% paragraph primitive (regardless of what \cs{par} may have as its +% current definition). In \LaTeX{} \cs{endgraf} with that behavior +% was also made available. +% +% With the new paragraph handling in \LaTeX{}, ending a paragraph +% means a bit more than just calling the engine's paragraph +% builder: the process also has to add any hook code for the end of +% a paragraph. Thus +% \cs{endgraf} was changed to provide this additional functionality +% (and so by extension \cs{par} subject to its current meaning). +% +% The \pkg{expl3} name for the functionality is \cs{para_end:}. +% \end{function} +% +% \begin{quote} +% \textbf{Note:} \em The next two commands are still under +% discussion and may slightly change their semantics (as described +% in the document) and/or their names between now and the 2021 +% Spring release! +% \end{quote} +% +% \begin{function}{\OmitIndent,\para_omit_indent:} +% Inside the \hook{para/begin} hook one can use this command to +% suppress the indentation box at the start of the +% paragraph. (Technically it is possible to use this command +% outside the hook as well, but this should not be relied upon.) +% The box itself remains available for use. +% +% The \pkg{expl3} name for the function is \cs{para_omit_indent:}. +% \end{function} +% +% \begin{variable}{\IndentBox,\g_para_indent_box} +% The box register holding the indentation box for the paragraph is +% available for inspection (or changes) inside hooks. It remains +% available even if the \cs{OmitIndent} command was +% used; in that case it will just not be automatically placed. +% +% The \pkg{expl3} name for the box register is \cs{g_para_indent_box}. +% \end{variable} +% +% +% \begin{function}{\RawIndent,\para_raw_indent:, +% \RawNoindent,\para_raw_noindent:, +% \RawParEnd,\para_raw_end:} +% \begin{syntax} +% \cs{RawIndent} \textit{hmode material} \cs{RawParEnd} +% \cs{RawNoindent} \textit{hmode material} \cs{RawParEnd} +% \end{syntax} +% +% The commands \cs{RawIndent} and \cs{RawNoindent} are not meant +% for normal paragraph building (where the result is a textual +% paragraph in the the traditional meaning of the word), but for +% special cases where \TeX{}'s low-level algorithm is used to +% achieve special effects, but where the result is not a +% \enquote{paragraph}. +% +% They are called \enquote{raw}, because they bypass \LaTeX{}'s +% hook mechanism for paragraphs and simply invoke the low-level +% \TeX{} algorithm. I.e., they are like the original \TeX{} +% primitives \cs{indent} and \cs{noindent} (that is they execute no +% hooks other than \cs{everypar}) except that they can only be used +% in vertical mode and generate an error if found elsewhere. +% +% To avoid issues a paragraph started by them should always be +% ended by \cs{RawParEnd}\footnote{Technical note for those who +% know their \textit{\TeX book\/}: the \cs{RawParEnd} comand +% invokes the original \TeX{} engine definition of \cs{par} that +% (soley) triggers the paragraph builder in \TeX{} when found +% inside unrestricted horizontal mode and does nothing in other +% processing modes.} +% and not by \cs{par} (or a blank line), because the latter will execute +% hooks which then have no counterpart at the beginning of the +% paragraph. It is the responsibility of the programmer to make +% sure that they are properly paired. This also means that one +% should not put arbitrary user content between these commands if +% that content could contain stray \cs{par}s. +% +% The \pkg{expl3} names for the functions are +% \cs{para_raw_indent:}, \cs{para_raw_indent:} and +% \cs{para_raw_end:}. +% \end{function} +% +% +% +% \subsection{Examples} +% +% None of the examples in this section are meant for real use as +% they are far too simpleminded but they should give some ideas of +% what could be possible if a bit more care is applied. +% +% \subsubsection{Testing the mechanism} +% +% The idea is to output for each paragraph encountered some +% information: a paragraph sequence number, a level number in roman +% numerals, the environment in which this paragraph appears, and +% the line number where the start or end of the paragraph is, e.g., +% something like +%\begin{verbatim} +% PARA: 1-i start (document env. on input line 38) +% PARA: 1-i end (document env. on input line 38) +% PARA: 2-i start (document env. on input line 40) +% PARA: 3-ii start (minipage env. on input line 40) +% PARA: 3-ii end (minipage env. on input line 40) +% PARA: 2-i end (document env. on input line 41) +%\end{verbatim} +% As you can see paragraph 2 starts on line 40 and ends on 41 and +% inside a minipage started paragraph 3 (start and end on line 40). +% If you run this on some document you will find that \LaTeX{} +% considers more things \enquote{a paragraph} than you have +% probably thought. +% +% This was generated by the following hook code: +%\begin{verbatim} +% \newcounter{paracnt} % sequence counter +% \newcounter{paralevel} % level counter +%\end{verbatim} +% +% To support paragraph nesting we need to maintain a stack of the +% sequence numbers. This is most easily done using \pkg{expl3} +% functions, so we switch over. This is not a very general +% implementation, just enough for what we need and a bit of +% \LaTeXe{} thrown in as well. When popping the result gets stored +% in \cs{paracntvalue} and the \cs{ERROR} should never happen +% because it means we have tried to pop from an empty stack. +%\begin{verbatim} +% \ExplSyntaxOn +% \seq_new:N \g_para_seq +% \cs_new:Npn \ParaPush +% {\seq_gpush:No \g_para_seq {\the\value{paracnt}}} +% \cs_new:Npn \ParaPop {\seq_gpop:NNF \g_para_seq \paracntvalue \ERROR } +% \ExplSyntaxOff +%\end{verbatim} +% At the start of the paragraph increment both sequence counter and +% level and also save the then current sequence number on our stack. +%\begin{verbatim} +% \AddToHook{para/begin}{% +% \stepcounter{paracnt}\stepcounter{paralevel}% +% \ParaPush +%\end{verbatim} +% To display the sequence number we \cs{typeout} the current +% sequence and level number. The command \cs{@currenvir} gives us +% the current environment and \cs{on@line} produces a space and +% the current input line number. +%\begin{verbatim} +% \typeout{PARA: \arabic{paracnt}-\roman{paralevel} start +% (\@currenvir\space env.\on@line)}% +%\end{verbatim} +% We also typeset the sequence number as a tiny red number in a box +% that takes up no horizontal space. This helps us seeing where +% \LaTeX{} sees the start and end of the paragraphs in the +% document. +%\begin{verbatim} +% \llap{\color{red}\tiny\arabic{paracnt}\ }% +% } +%\end{verbatim} +% +% At the end of the paragraph we display sequence number and +% level again. The level counter has the correct value but we need +% to retrieve the right sequence value by popping it off the stack +% after which it is available in \cs{paracntvalue} the way we have +% set this up above. +%\begin{verbatim} +% \AddToHook{para/end}{% +% \ParaPop +% \typeout{PARA: \paracntvalue-\roman{paralevel} end \space\space +% (\@currenvir\space env.\on@line)}% +%\end{verbatim} +% We also typeset again a tiny red number with that value, this +% time sticking out to the right.\footnote{Note that this can alter +% the document pagination, because a paragraph ending in a display +% (e.g., an equation) will get an extra line---in that case our tiny number +% has an effect even though it doesn't take up any space, because +% it paragraph is no longer empty and thus isn't dropped!} +% We also decrement the level counter since our level has finished. +%\begin{verbatim} +% \rlap{\color{red}\tiny\ \paracntvalue}% +% \addtocounter{paralevel}{-1}% +% } +% \makeatother +%\end{verbatim} +% +% +% +% \subsubsection{Mark the first paragraph of each \env{itemize}} +% +% The code for this is rather simple. We apply hook code that is +% executed only once inside a hook that is executed at the begin of +% each \env{itemize}. We explicitly change the color back and +% forth so that we don't introduce grouping around the paragraph. +%\begin{verbatim} +% \AddToHook{env/itemize/begin}{% +% \AddToHookNext{para/begin}{\color{blue}}% +% \AddToHookNext{para/end}{\color{black}}% +% } +%\end{verbatim} +% As a result the first paragraph of each \env{itemize} will appear +% in blue. +% +% +% +% \subsection{Some technical notes} +% +% The code tries hard to be transparent for package code, but of +% course any change means that there is a potential for breaking +% other code. So in section we collect a few cases that may be of +% importance if low-level code is dealing with paragraphs that are +% now behaving slightly differently. The notes are from issues we +% observed and will probably grow over time. +% +% \subsubsection{Glue items between paragraphs (found with \pkg{fancypar})} +% +% In the past \LaTeX{} placed two glue items between two +% consecutive paragraph, e.g., +%\begin{verbatim} +% text1 \par text2 \par +%\end{verbatim} +% would show something like +%\begin{verbatim} +% \glue(\parskip) 0.0 plus 1.0 +% \glue(\baselineskip) 5.16669 +%\end{verbatim} +% but now there is anothe \cs{parskip} glue (that is always 0pt): +%\begin{verbatim} +% \glue(\parskip) 0.0 plus 1.0 +% \glue(\parskip) 0.0 +% \glue(\baselineskip) 5.16669 +%\end{verbatim} +% The reason is that we generate a \enquote{fake}'' paragraph to +% gain control and safely add the early hooks, but this generates +% an additional glue item. That item doesn't contribute anything +% vertically but ifsomebody writes code the unravels a constructed +% list using \cs{lastbox}, \cs{unskip} and \cs{unpenalty} then the +% code has to remove one additional glue item or else will fail. + +% +% ^^A \subsubsection{} +% +% +% +% ^^A \subsubsection{} +% +% +% +% +% +% +% \StopEventually{\setlength\IndexMin{200pt} \PrintIndex } +% +% +% \section{The Implementation} +% +% \begin{macrocode} +%<@@=para> +% \end{macrocode} +% +% \changes{v1.0g}{2021/05/24}{Use \cs{msg_...} instead of \cs{__kernel_msg...}} +% +% +% \begin{macrocode} +%<*2ekernel|latexrelease> +\ExplSyntaxOn +%<latexrelease>\NewModuleRelease{2021/06/01}{ltpara} +%<latexrelease> {Paragraph~handling~and~hooks} +% \end{macrocode} +% +% +% +% \subsection{Providing hooks for paragraphs} +% +% +% \begin{macro}{para/before,para/after,para/begin,para/end} +% The public hooks.

Otherwise the process change remains +% transparent to any legacy code for this space. +% +% We keep the standard code to be used by \cs{tex_everypar:D} in a +% separate token list because we have to switch back and forth +% for error recovery and so altering \cs{tex_everypar:D} all the +% time should be a tiny bit faster. +% \begin{macrocode} +\tl_new:N \g_@@_standard_everypar_tl +% \end{macrocode} +% Here is now its definition: +% \begin{macrocode} +\tl_gset:Nn \g_@@_standard_everypar_tl { +% \end{macrocode} +% First we remove the indentation box and store it in +% \cs{g_para_indent_box}.

And we need to make sure not to get another +% \cs{parskip} or rather (since we can't prevent that) that it is +% of zero size. +% \begin{macrocode} + \group_begin: + \tex_everypar:D {} + \skip_zero:N \tex_parskip:D + \tex_noindent:D + \group_end: +% \end{macrocode} +% That brings us back to the start of the horizontal list but we +% need to change \cs{tex_everypar:D} back to its normal content in +% case there are nested paragraphs coming up. +% \begin{macrocode} + \tex_everypar:D{\g_@@_standard_everypar_tl} +% \end{macrocode} +% +% This is followed by executing the kernel and the public hook.

That is +% they assume that \cs{everypar} is the primitive and that it will +% still be called at the start of the paragraph even if renamed. +% +% But if we have already replaced it by a token register then all +% they do is to give that token register a new name. Thus our code +% in \cs{tex_everypar:D} would call \cs{everypar} (which is their +% now token register) and the code that they added ends up in our +% token register which is then never used at all. A bit mind +% boggling I guess. +% +% So what we have to do is not to call the token register +% \cs{everypar} by its name inside \cs{tex_everypar:D} but by using +% its actual register number. +% \begin{macrocode} +\newtoks \everypar +% \end{macrocode} +% +% After we have allocated a new toks register with the name +% \cs{everypar} the actual register number is available (briefly) +% inside \cs{allocationnumber}. So instead of \cs{the}\cs{everypar} +% we have to put \cs{the}\cs{toks}\meta{allocated number} at the end of +% \cs{tex_everypar:D}. +% +% So what remains doing is to append a few tokens to the token list +% \cs{g_@@_standard_everypar_tl} which we do now. We use \texttt{x} +% expansion here to get the value of \cs{allocationnumber} in, all +% the other tokens should not be expanded at this point. + +% One important point here is to terminate the register allocation +% number with a real space. This space will get swallowed up when +% the number is read. Anything else, such as \cs{scan_stop:} would +% remain in the input and that would mean that it would interfere +% with \cs{everypar} code that attempts to scan ahead to see how +% the paragraph text starts. +% \begin{macrocode} +\tl_gput_right:Nx \g_@@_standard_everypar_tl { + \exp_not:N \the + \exp_not:N \toks + \the \allocationnumber + \c_space_tl +} +% \end{macrocode} +% \end{macro} +% +% +% \begin{macro}{\g_para_indent_box} +% For managing the indentation we need to provide a public +% accessible box register +% \begin{macrocode} +\box_new:N \g_para_indent_box +% \end{macrocode} +% \end{macro} + +% \begin{macro}{\@@_handle_indent:} +% Adding (typesetting) the indent box is straight forward. +% If it was emptied before it does nothing. +% \begin{macrocode} +\cs_new:Npn \@@_handle_indent: { + \box_use_drop:N \g_para_indent_box +} +% \end{macrocode} +% The declaration \cs{para_omit_indent:} (or +% \cs{OmitIndent}) changes that to do nothing. +% \begin{macrocode} +\cs_new:Npn \para_omit_indent: { + \box_gclear:N \g_para_indent_box +} +% \end{macrocode} +% \end{macro} +% +% +% \begin{macro}{\IndentBox,\OmitIndent} +% The \LaTeXe{} names for the indentation box and for suppressing it +% for use in the \hook{para/begin} hook. +% \begin{macrocode} +\cs_set_eq:NN \IndentBox \g_para_indent_box +\cs_set_eq:NN \OmitIndent \para_omit_indent: +% \end{macrocode} +% \end{macro} +% +% +% +% +% +% +% \begin{macro}{\para_end:} +% Adding hooks to the end of a paragraph is similar but here we +% need to alter the command that is used by \TeX{} to end horizontal +% mode and return to vertical mode, i.e., \cs{par}. +% +% This is a bit more complicated as this command can appear anywhere +% either explicitly or implicitly added by \TeX{} in certain +% situations: +% \begin{itemize} +% \item +% when using \cs{par} in the code or the document +% \item +% when using a blank line (which is converted to \cs{par}) +% \item +% when \TeX{} finds any commands incompatible with horizontal +% mode it issues a \cs{par} and then rereads the command. +% \end{itemize} +% +% Unfortunately, \TeX{} has some (these days) unnecessary +% optimization: if a \cs{vbox} ends and \TeX{} is still in +% horizontal mode it simply exercises the paragraph builder instead +% of issuing a \cs{par}. It is therefore necessary for \LaTeX{} to +% ensure that this case doesn't happen and all boxes internally +% have a \cs{par} command at their end. +% +% This \cs{par} may or may not run the ``par primitive'' (which is +% always available as \cs{tex_par:D} in \pkg{expl3}); it is +% permissible to have a changed meaning and it is in fact changed +% by \LaTeX{} in various ways at various points inside +% \texttt{latex.ltx}. For this \LaTeXe{} code has the following +% conventions: \cs{@@@@par} and \cs{endgraf} both refer to the +% default meaning (in the past this was the initex primitive) while +% \cs{par} is the current meaning which may does something else. +% +% +% We are now going to change this default meaning to run +% \cs{para_end:} instead, which ultimately executes the initex +% primitive but additionally adds our hooks when appropriate. +% This way the change is again transparent to the legacy \LaTeXe{} +% code. +% +% In most cases \cs{para_end:} should behave exactly like the +% primitive and we achieve this by simply expanding it to the +% primitive which is available to us as \cs{tex_par:D}. This way we +% don't have to care about whether \TeX{} just does nothing (e.g., +% if in vertical mode already) or generate an error, etc. +% \begin{macrocode} +\cs_new_protected:Npn \para_end: { +% \end{macrocode} +% +% The only case we care about is when we are in horizontal mode +% (i.e., doing typesetting) and not also in inner mode (i.e., +% making paragraphs and not building an \cs{hbox}. +% \begin{macrocode} +% \bool_lazy_and:nnT +% { \mode_if_horizontal_p: } +% { \bool_not_p:n { \mode_if_inner_p: } } +% { ... +% \end{macrocode} +% Since this is executed for each and every paragraph in a document +% we try to stay a fast as possible, So we are aren't using the +% above construct but two conditionals instead. Using low-level +% \cs{if_mode...} conditions would be even faster but has the +% danger to conflict with conditionals in the user hooks. +% \begin{macrocode} + \mode_if_horizontal:TF { + \mode_if_inner:F { +% \end{macrocode} +% In that case the action of the primitive would be to remove the +% last glue (not kern) from the horizontal list constructed to form +% a paragraph then append the a penalty of 10000 and the +% \cs{parfillskip} at the end and pass the whole list to the +% paragraph builder which breaks it into lines and \TeX{} then +% returns to vertical mode. +% +% What we want to do instead is to add our hook code at the end of +% the horizontal list before that happens and the code is passed to +% the paragraph builder. If there was a glue item at the end then +% it should get removed before the hook code gets added so we have +% to arrange for its removal ourselves. +% +% There is not much point in checking if there was really a glue +% item at the end of the horizontal list, instead we simply try to +% remove one using \cs{tex_unskip:D}, if there wasn't one this will +% do nothing. +% \begin{macrocode} + \tex_unskip:D +% \end{macrocode} +% The we execute the public hook (which may add final typesetting +% material) followed by the kernel hook we need for adding tagging +% support. None of this is supposed to change the mode---at the +% moment we make only a very simple test for this, more devious +% changes go unnoticed, but too bad, that will then probably +% badly backfire. +% \begin{macrocode} + \hook_use:n{para/end} + \@kernel@after@para@end + \mode_if_horizontal:TF { +% \end{macrocode} +% The final action (before getting to the point where +% \cs{tex_par:D} is called) is to add a kern item so that the +% primitive is prevented from removing glue (if there was some). If +% we don't do this and the +% horizontal list ended in several glue items we would end up with +% removing two instead of just the last one, which would be wrong. +% We use a kern as that is minimally faster. +% +% There is however one other \TeX{} optimization that hurts: in a +% sequence like this \verb=$$ ... $$ \par= \TeX{} will be in +% horizontal mode after the display, ready to receive further +% paragraph text, but since the \cs{par} follows immediately there +% is a ``null'' paragraph at the end and \TeX{} simply throws that +% away. The space between \verb=$$= and \cs{par} got already +% dropped during the display processing so the \cs{par} is not +% removing any space and appending \cs{parfillskip}, instead it +% simply goes silently to vmode. Now if we would had added something (to +% prevent glue removal) that would look to \TeX{} like material +% after the display and so we would end up with an empty paragraph +% just containing \cs{parfillskip}. +% +% We therefore check if the current hlist is empty +% (\cs{tex_lastnodetype:D} has the value \texttt{-1} and +% only if not we add our kern. +% \begin{macrocode} + \if_int_compare:w 0 < \tex_lastnodetype:D + \tex_kern:D \c_zero_dim + \fi: +% \end{macrocode} +% To run the \hook{para/after} hook we first end the +% paragraph.
