This even allows you to copy commands that consist of several internal +components, such as robust commands or those with a complex signature. +To do the same with environments, e.g., to define the environment +\env{myitemize} to be equivalent to \env{itemize}, you can now write +\begin{verbatim} + \NewEnvironmentCopy{myitemize}{itemize} +\end{verbatim} +There are also \cs{Renew...}\ and \cs{Declare...}, which may be useful +depending on the circumstances. + +In addition, we offer a \cs{ShowEnvironment} command, which displays the +\cs{begin} and \cs{end} code of the environment passed as an +argument. E.g., \verb=\ShowEnvironment{center}= results in the +following output: +\begin{verbatim} + > \begin{center}=environment: + > ->\trivlist \centering \item \relax . + <recently read> } + l. ...\ShowEnvironment{center} + > \end{center}: + > ->\endtrivlist . + <recently read> } + l. ...\ShowEnvironment{center} +\end{verbatim} +% +\githubissue{963} + + + + +\section{Code improvements} + +\subsection{\pkg{doc}: Index \texttt{\textbackslash\textvisiblespace} correctly} + +\emph{to write} +% +\githubissue{943} + + +\subsection{\pkg{doc}: Support the \pkg{upquote} package} + +The default quote and backquote characters in typewriter fonts are +typographical quotes, e.g., the input +\begin{verbatim} + \verb*/`prog 'my input'`/ +\end{verbatim} + is rendered as \verb*/`prog 'my input'`/ and not as +% +\begingroup % code to mimic upquote.sty +\catcode`'=\active +\catcode``=\active +\makeatletter +\g@addto@macro\@noligs + {\let'\textquotesingle + \let`\textasciigrave + \ifx\encodingdefault\upquote@OTone + \ifx\ttdefault\upquote@cmtt + \def'{\char13 }% + \def`{\char18 }% + \fi\fi} +\endgroup +% +\verb*/`prog 'my input'`/ as preferred by many programmers. + +This can be adjusted, for example, with the \pkg{upquote} package, +which results in the second output. However, for historical reasons +\pkg{doc} had its own definition of \cs{verb} and \env{verbatim} and +as a consequence the two packages did not cooperate. This has now +been fixed and loading \pkg{upquote} together with \pkg{doc} has the +desired effect. +% +\githubissue{953} + + +\subsection{New key for \env{filecontents}} + +The \env{filecontents} environment warns on the terminal if a file +gets overwritten even if that is intentional, +e.g., when you write a temporary file over and over again. To make +the warning less noisy in this case we added a new \texttt{nowarn} key +that redirects the overwriting warning to the transcript file. We +think that some record of the action is still required to help with +debugging, thus it is not completely silenced. The warning that +nothing gets written, because the file aready exists (and the +\texttt{force} key was not used), is not altered and still shows up on +the terminal. +% +\githubissue{958} + + + +\subsection{A further hook for shipping out pages} + +Since October 2020 the shipout process offers a number of hooks to +adjust what is happening before, during, and after the +\cs{shipout}. For example, with the \hook{shipout/before} hook, packages +can reset code they have altered (e.g., \cs{catcode}s during +verbatim-like processing) and with \hook{shipout/background} and +\hook{shipout/foreground} material can be added to the pages. +Details are given in \cite{37:ltshipout-doc}. However, what was +missing was a hook that allows a package writer to manipulate the +completed page (with foreground and background attached) just before +the actual shipout happens. + +For this we now provide the additional hook \hook{shipout}. One +use case (sometimes needed in print production) is to mirror the +whole page via \cs{reflectbox} including all the extra data that may +have been added into the fore- or background. +% +\githubissue{920} + + + +\subsection{Displaying release information in the \texttt{.log}} + +\LaTeX{} displays its release information at the very beginning of the +\LaTeX{} run on the terminal and also writes it to the transcript file +if that is already opened at this point. While this is normally true, +it is not the case if the \LaTeX{} run was started passing additional +\TeX{} code on the command line, e.g., +\begin{verbatim} +pdflatex '\PassOptionsToClass{11pt}{article} + \input{myarticle}' +\end{verbatim} +In this case the release information is displayed when +\cs{PassOptionsToClass} is processed but the transcript file is only +opened when the output file name is known, i.e., after \cs{input} has +been seen, and as a result the release information is only shown on +the terminal. + +To account for this scenario, we now repeat the release information +also at the very end of the transcript file where we can be sure that +it is open and ready to receive material. +% +\githubissue{944} + + + + + +\section{Bug fixes} + +\subsection{Incompatibility between \pkg{doc} and \pkg{unicode-math}} + +The \pkg{unicode-math} package alters the catcode of \verb=|= but does +not adjust its value for use in \pkg{doc}, with the result that +\enquote{or} module, i.e., $\langle A | B \rangle$ are displayed in a +strange way. This is now fixed with some firstaid code that will +eventually be moved into \pkg{unicode-math}. +% +\githubissue{820} + + +\subsection{A fix for \cs{hspace}} + +The change to \cs{hspace}, done in 2020 to make it \pkg{calc} aware, +had the unfortunate side effect that starting a paragraph with +\cs{hspace} would result in the execution of \cs{everypar} inside a +group (i.e., any local changes would immediately be revoked, breaking, +for example, \pkg{wrapfig} in that special situation). +% +This got fixed with the 2022-11 PL1 hotfix, so was already corrected in +the previous release, but
