+\section{Introduction}
+
+This document is an introduction to writing classes and packages for
+\LaTeX{}, with special attention given to upgrading existing
+\LaTeX~2.09 packages to \LaTeXe{}. The latter subject is also
+covered in an article by Johannes Braams published in TUGboat~15.3.
+
+It is somewhat of an historical document now, since \LaTeXe{} came into
+existence in 1994.
+
+\subsection{Writing classes and packages for \LaTeXe}
+
+\LaTeX{} is a document preparation system that enables the document
+writer to concentrate on the contents of their text, without bothering
+too much about the formatting of it. For example, chapters are
+indicated by |\chapter{<title>}| rather than by selecting 18pt bold.
+
+The file that contains the information about how to turn logical
+structure (like `|\chapter|') into formatting (like `18pt bold ragged
+right') is a \emph{document class}. In addition, some features (such
+as colour or included graphics) are independent of the document class
+and these are contained in \emph{packages}.
+
+One of the largest differences between \LaTeX~2.09 and \LaTeXe{} is in
+the commands used to write packages and classes. In \LaTeX~2.09,
+there was very little support for writing |.sty| files, and so writers
+had to resort to using low-level commands.
+
+\LaTeXe{} provides high-level commands for structuring packages.
+It is also much easier to build classes and packages on top of each
+other, for example writing a local technical report class |cetechr|
+(for the Chemical Engineering department) based on |article|.
+
+\subsection{Overview}
+
+This document contains an overview of how to write classes and
+packages for \LaTeX{}. It does \emph{not} introduce all of the
+commands necessary to write packages: these can be found in either
+\emph{\LaTeXbook} or \emph{\LaTeXcomp}. But it does describe the new
+commands for structuring classes and packages.
+
+\begin{description}
+
+\item[Section~\ref{Sec:general}] contains some general advice about
+ writing classes and packages. It describes the difference between
+ classes and packages, the command naming conventions, the use of
+ |doc| and |docstrip|, how \TeX's primitive file and box commands
+ interact with \LaTeX{}. It also contains some hints about general
+ \LaTeX{} style.
+
+\item[Section~\ref{Sec:structure}] describes the structure of classes
+ and packages. This includes building classes and packages on top of
+ other classes and packages, declaring options and declaring
+ commands. It also contains example classes.
+
+\item[Section~\ref{Sec:commands}] lists the new class and package
+ commands.
+
+ \item[Section~\ref{Sec:upgrade}] gives detailed advice on how to
+ upgrade existing \LaTeX~2.09 classes and packages to \LaTeXe{}.
+
+\end{description}
+
+\subsection{Further information}
+
+For a general introduction to \LaTeX{}, including the new features of
+\LaTeXe{}, you should read \emph{\LaTeXbook}
+by Leslie Lamport~\cite{A-W:LLa94}.
+
+A more detailed description of the new features of \LaTeX, including an
+overview of more than 200 packages and nearly 1000 ready to run examples, is
+to be found in \emph{\LaTeXcomp\ second edition} by Frank Mittelbach and
+Michel Goossens~\cite{A-W:MG2004}.
+
+The \LaTeX{} system is based on \TeX{}, which is
+described in \emph{The \TeX book} by Donald E.~Knuth~\cite{A-W:DEK91}.
+
+There are a number of documentation files which accompany every copy
+of \LaTeX{}. A copy of \emph{\LaTeX{} News} will come out with each
+six-monthly release of \LaTeX{}, and is found in the files
+|ltnews*.tex|. The author's guide \emph{\usrguide} describes the new
+\LaTeX{} document features; it is in |usrguide.tex|. The guide
+\emph{\fntguide} describes the \LaTeX{} font selection scheme for
+class- and package-writers; it is in |fntguide.tex|. Configuring
+\LaTeX{} is covered by the guide \emph{\cfgguide} in
+\texttt{cfgguide.tex} whilst the philosophy behind our policy on
+modifying \LaTeX{} is described in \emph{\modguide} in
+\texttt{modguide.tex}.
+
+The documented source code (from the files used to produce the kernel
+format via |latex.ltx|) is now available as
+\emph{The \LaTeXe\ Sources}.
+This very large document also includes an index of
+\LaTeX{} commands. It can be typeset from the \LaTeX{} file
+|source2e.tex| in the |base| directory, using the source files and
+the class file |ltxdoc.cls| from this directory.
+
+For more information about \TeX{} and \LaTeX{}, please contact your
+local \TeX{} Users Group, or the international \TeX{} Users Group.
+Addresses and other details can be found at:

+\end{quote}
+
+
+\subsection{Policy on standard classes}
+
+Many of the problem reports we receive concerning the standard classes
+are not concerned with bugs but are suggesting, more or less politely,
+that the design decisions embodied in them are `not optimal' and
+asking us to modify them.
+
+There are several reasons why we should not make such changes to these
+files.
+\begin{itemize}
+\item
+ However misguided, the current behaviour is clearly what was
+ intended when these classes were designed.
+\item
+ It is not good practice to change such aspects of `standard classes'
+ because many people will be relying on them.
+\end{itemize}
+
+We have therefore decided not to even consider making such
+modifications, nor to spend time justifying that decision. This does
+not mean that we do not agree that there are many deficiencies in the
+design of these classes, but we have many tasks with higher priority
+than continually explaining why the standard classes for \LaTeX{}
+cannot be changed.
+
+We would, of course, welcome the production of better classes, or of
+packages that can be used to enhance these classes. So your first
+thought when you consider such a deficiency will, we hope, be ``what
+can I do to improve this?''
+
+Similar considerations apply to those parts of the kernel that are
+implementing design decisions, many of which should be left to the
+class file but are not in the current system. We realise that in such
+cases it is much more difficult for you to rectify the problem
+yourself but it is also the case that making such changes in the
+kernel would probably be a major project for us; therefore such
+enhancements will have to wait for \LaTeX3.
+
+\section{Writing classes and packages}
+\label{Sec:writing}
+
+This section covers some general points concerned with writing
+\LaTeX{} classes and packages.
+
+
+\subsection{Old versions}
+
+If you are upgrading an existing \LaTeX~2.09 style file then we
+recommend freezing the 2.09 version and no longer maintaining it.
+Experience with the various dialects of \LaTeX{} which existed in the
+early 1990's suggests that maintaining packages for different versions
+of \LaTeX{} is almost impossible. It will, of course, be necessary
+for some organisations to maintain both versions in parallel for some
+time but this is not essential for those packages and classes
+supported by individuals: they should support only the new standard
+\LaTeXe{}, not obsolete versions of \LaTeX{}.
+
+
+\subsection{Using `docstrip' and `doc'}
+
+If you are going to write a large class or package for \LaTeX{} then
+you should consider using the |doc| software which comes with
+\LaTeX{}.
+\LaTeX{} classes and packages written using this can be
+processed in two ways: they can be run through \LaTeX{}, to produce
+documentation; and they can be processed with |docstrip|, to produce
+the |.cls| or |.sty| file.
+
+The |doc| software can automatically generate indexes of definitions,
+indexes of command use, and change-log lists. It is very useful for
+maintaining and documenting large \TeX{} sources.
+
+The documented sources of the \LaTeX{} kernel itself, and of the
+standard classes, etc, are |doc| documents; they are in the |.dtx|
+files in the distribution. You can, in fact, typeset the source code
+of the kernel as one long document, complete with index, by running
+\LaTeX{} on |source2e.tex|. Typesetting these documents uses the
+class file |ltxdoc.cls|.
+
+For more information on |doc| and |docstrip|, consult the files
+|docstrip.dtx|, |doc.dtx|, and \emph{\LaTeXcomp}. For examples of its
+use, look at the |.dtx| files.
+
+\subsection{Is it a class or a package?}
+\label{Sec:classorpkg}
+
+The first thing to do when you want to put some new \LaTeX{} commands
+in a file is to decide whether it should be a \emph{document class} or a
+\emph{package}. The rule of thumb is:
+\begin{quote}
+ If the commands could be used with any document class, then make
+ them a package; and if not, then make them a class.
+\end{quote}
+
+There are two major types of class: those like |article|, |report| or
+|letter|, which are free-standing; and those which are extensions or
+variations of other classes---for example, the |proc| document class,
+which is built on the |article| document class.
+
+Thus, a company might have a local |ownlet| class for printing letters
+with their own headed note-paper. Such a class would build on top of
+the existing |letter| class but it cannot be used with any other
+document class, so we have |ownlet.cls| rather than |ownlet.sty|.
+
+The |graphics| package, in contrast, provides commands for including
+images into a \LaTeX{} document. Since these commands can be used
+with any document class, we have |graphics.sty| rather than
+|graphics.cls|.
+
+
+\subsection{Command names}
+
+\LaTeX{} has three types of command.
+
+There are the author commands, such as |\section|, |\emph| and
+|\times|: most of these have short names, all in lower case.
+
+There are also the class and package writer commands:
+most of these have long mixed-case names such as the following.
+\begin{verbatim}
+ \InputIfFileExists \RequirePackage \PassOptionsToClass
+\end{verbatim}
+
+Finally, there are the internal commands used in the \LaTeX{}
+implementation, such as |\@tempcnta|, |\@ifnextchar| and |\@eha|:
+most of these commands contain |@| in their name, which means they
+cannot be used in documents, only in class and package files.
+
+Unfortunately, for historical reasons the distinction between these
+commands is often blurred. For example, |\hbox| is an internal
+command which should only be used in the \LaTeX{} kernel, whereas
+|\m@ne| is the constant $-1$ and could have been |\MinusOne|.
+
+However, this rule of thumb is still useful: if a command has |@| in
+its name then it is not part of the supported \LaTeX{} language---and
+its behaviour may change in future releases! If a command is
+mixed-case, or is described in \emph{\LaTeXbook}, then you can rely on
+future releases of \LaTeXe{} supporting the command.
+
+\subsection{Box commands and colour}
+\label{Sec:colour}
+
+Even if you do not intend to use colour in your own documents, by
+taking note of the points in this section you can ensure that your
+class or package is compatible with the |color| package. This may
+benefit people using your class or package who have access to colour
+printers.
+
+The simplest way to ensure `colour safety' is to always use \LaTeX{}
+box commands rather than \TeX{} primitives, that is use |\sbox| rather
+than |\setbox|, |\mbox| rather than |\hbox| and |\parbox| or
+the |minipage| environment rather than |\vbox|.
+The \LaTeX{} box commands have new options which mean that they are now
+as powerful as the \TeX{} primitives.
+
+As an example of what can go wrong, consider that in
+|{\ttfamily <text>}|
+the font is restored just \emph{before} the |}|, whereas in the
+similar looking construction
+|{\color{green} <text>}|
+the colour is restored just \emph{after} the final |}|. Normally this
+distinction does not matter at all; but consider a primitive \TeX{}
+box assignment such as:
+\begin{verbatim}
+ \setbox0=\hbox{\color{green} <text>}
+\end{verbatim}
+Now the colour-restore occurs after the |}| and so is \emph{not}
+stored in the box. Exactly what bad effects this can have depends on
+how colour is implemented: it can range from getting the wrong
+colours in the rest of the document, to causing errors in the
+dvi-driver used to print the document.
+
+Also of interest is the command |\normalcolor|. This is
+normally just |\relax| (i.e., does nothing)
+but you can use it rather like |\normalfont| to
+set regions of the page such as captions or section headings to the
+`main document colour'.
+
+
+\subsection{Defining text and math characters}
+\label{Sec:chars}
+
+Because \LaTeXe{} supports different encodings, definitions of commands
+for producing symbols, accents, composite glyphs, etc.\ must be
+defined using the commands provided for this purpose and described in
+\emph{\fntguide}. This part of the system is still under development
+so such tasks should be undertaken with great caution.
+
+Also, |\DeclareRobustCommand| should be used for encoding-independent
+commands of this type.
+
+Note that it is no longer possible to refer to the math font set-up
+outside math mode: for example, neither |\textfont 1| nor
+|\scriptfont 2| are guaranteed to be defined in other modes.
+
+
+\subsection{General style}
+\label{Sec:general}
+
+The new system provides many commands designed to help you produce
+well-structured class and package files that are both robust and
+portable. This section outlines some ways to make intelligent use of
+these.
+
+\subsubsection{Loading other files}
+\label{Sec:loading}
+
+\NEWdescription{1995/12/01}
+\LaTeX{} provides these commands:
+\begin{verbatim}
+ \LoadClass \LoadClassWithOptions
+ \RequirePackage \RequirePackageWithOptions
+\end{verbatim}
+for using classes or packages inside other classes or packages. We
+recommend strongly that you use them, rather than the primitive
+|\input| command, for a number of reasons.
+
+Files loaded with |\input <filename>| will not be listed in the
+|\listfiles| list.
+
+If a package is always loaded with |\RequirePackage...| or |\usepackage|
+then, even if its loading is requested several times, it will be
+loaded only once. By contrast, if it is loaded with |\input| then it
+can be loaded more than once; such an extra loading may waste time and
+memory and it may produce strange results.
+
+If a package provides option-processing then, again, strange results
+are possible if the package is |\input| rather than loaded by means of
+|\usepackage| or |\RequirePackage...|.
+
+If the package |foo.sty| loads the package |baz.sty| by use of
+|\input baz.sty| then the user will get a warning:
+\begin{verbatim}
+ LaTeX Warning: You have requested package `foo',
+ but the package provides `baz'.
+\end{verbatim}
+Thus, for several reasons, using |\input| to load packages is not a
+good idea.
+
+Unfortunately, if you are upgrading the file |myclass.sty| to a class
+file then you have to make sure that any old files which contain
+|\input myclass.sty| still work.
+
+This was also true for the standard classes (|article|, |book| and
+|report|), since a lot of existing \LaTeX~2.09 document styles contain
+|\input article.sty|. The approach which we use to solve this is
+to provide minimal files |article.sty|, |book.sty| and |report.sty|,
+which simply load the appropriate class files.
+
+For example, |article.sty| contains just the following lines:
+\begin{verbatim}
+ \NeedsTeXFormat{LaTeX2e}
+ \@obsoletefile{article.cls}{article.sty}
+ \LoadClass{article}
+\end{verbatim}
+You may wish to do the same or, if you think that it is safe to do so,
+you may decide to just remove |myclass.sty|.
+
+\subsubsection{Make it robust}
+
+We consider it good practice, when writing packages and classes, to use
+\LaTeX{} commands as much as possible.
+
+Thus, instead of using |\def...| we recommend using one of
+|\newcommand|, |\renewcommand| or |\providecommand|; |\CheckCommand| is
+also useful. Doing this makes
+it less likely that you will inadvertently redefine a command, giving
+unexpected results.
+
+When you define an environment, use |\newenvironment| or
+|\renewenvironment| instead |\def\foo{...}| and |\def\endfoo{...}|.
+
+If you need to set or change the value of a \m{dimen} or \m{skip}
+register, use |\setlength|.
+
+To manipulate boxes, use \LaTeX{} commands such as |\sbox|,
+|\mbox| and |\parbox| rather than |\setbox|, |\hbox| and |\vbox|.
+
+Use |\PackageError|, |\PackageWarning| or |\PackageInfo| (or the
+equivalent class commands) rather than |\@latexerr|, |\@warning| or
+|\wlog|.
+
+It is still possible to declare options by defining |\ds@<option>| and
+calling |\@options|; but we recommend the |\DeclareOption| and
+|\ProcessOptions| commands instead. These are more powerful and use
+less memory. So rather than using:
+\begin{verbatim}
+ \def\ds@draft{\overfullrule 5pt}
+ \@options
+\end{verbatim}
+you should use:
+\begin{verbatim}
+ \DeclareOption{draft}{\setlength{\overfullrule}{5pt}}
+ \ProcessOptions\relax
+\end{verbatim}
+
+The advantage of this kind of practice is that your code is more
+readable and, more important, that it is less likely to break when
+used with future versions of \LaTeX{}.
+
+\subsubsection{Make it portable}
+
+It is also sensible to make your files are as portable as possible. To
+ensure this; they should contain only visible 7-bit text; and the
+filenames should contain at most eight characters (plus the three
+letter extension). Also, of course, it \textbf{must not} have the
+same name as a file in the standard \LaTeX{} distribution, however
+similar its contents may be to one of these files.
+
+It is also useful if local classes or packages have a common prefix,
+for example the University of Nowhere classes might begin with |unw|.
+This helps to avoid every University having its own thesis class, all
+called |thesis.cls|.
+
+If you rely on some features of the \LaTeX{} kernel, or on a package,
+please specify the release-date you need. For example, the package
+error commands were introduced in the June 1994 release so, if you use
+them then you should put:
+\begin{verbatim}
+ \NeedsTeXFormat{LaTeX2e}[1994/06/01]
+\end{verbatim}
+
+\subsubsection{Useful hooks}
+
+Some packages and document styles had to redefine the command
+|\document| or |\enddocument| to achieve their goal. This is no
+longer necessary. You can now use the `hooks' |\AtBeginDocument| and
+|\AtEndDocument| (see Section~\ref{Sec:delays}). Again, using these
+hooks makes it less likely that your code breaks with future versions
+of \LaTeX{}. It also makes it more likely that your package can work
+together with someone else's.
+
+\NEWdescription{1996/12/01}
+However, note that code in the |\AtBeginDocument| hook is part of the
+preamble. Thus there are restrictions on what can be put there; in
+particular, no typesetting can be done.
+
+\section{The structure of a class or package}
+\label{Sec:structure}
+
+\LaTeXe{} classes and packages have more structure than \LaTeX~2.09
+style files did. The outline of a class or package file is:
+\begin{description}
+\item[Identification] The file says that it is a \LaTeXe{} package or
+ class, and gives a short description of itself.
+\item[Preliminary declarations]
+ Here the file declares some commands and can also load
+ other files. Usually these commands will be just those needed for
+ the code used in the declared options.
+\item[Options] The file declares and processes its options.
+\item[More declarations] This is where the file does most of its work:
+ declaring new variables, commands and fonts; and loading other files.
+\end{description}
+
+\subsection{Identification}
+
+The first thing a class or package file does is identify itself.
+Package files do this as follows:
+\begin{verbatim}
+ \NeedsTeXFormat{LaTeX2e}
+ \ProvidesPackage{<package>}[<date> <other information>]
+\end{verbatim}
+For example:
+\begin{verbatim}
+ \NeedsTeXFormat{LaTeX2e}
+ \ProvidesPackage{latexsym}[1994/06/01 Standard LaTeX package]
+\end{verbatim}
+Class files do this as follows:
+\begin{verbatim}
+ \NeedsTeXFormat{LaTeX2e}
+ \ProvidesClass{<class-name>}[<date> <other information>]
+\end{verbatim}
+For example:
+\begin{verbatim}
+ \NeedsTeXFormat{LaTeX2e}
+ \ProvidesClass{article}[1994/06/01 Standard LaTeX class]
+\end{verbatim}
+\NEWdescription{1998/06/19}
+The \m{date} should be given in the form `\textsc{yyyy/mm/dd}' and
+must be present if the optional argument is used (this is also true
+for the |\NeedsTeXFormat| command).
+Any derivation from this syntax will result in low-level \TeX{}
+errors---the commands expect a valid syntax to speed up the daily
+usage of the package or class and make no provision for the case that
+the developer made a mistake!
+
+This date is checked whenever a user specifies a date in their
+|\documentclass| or |\usepackage| command. For example, if you wrote:
+\begin{verbatim}
+ \documentclass{article}[1995/12/23]
+\end{verbatim}
+then users at a different location
+would get a warning that their copy of |article| was out of
+date.
+
+The description of a class is displayed when the class is used. The
+description of a package is put into the log file. These descriptions
+are also displayed by the |\listfiles| command. The phrase
+\texttt{Standard LaTeX} \textbf{must not} be used in the identification
+banner of any file other than those in the standard \LaTeX{}
+distribution.
+
+
+\subsection{Using classes and packages}
+
+The first major difference between \LaTeX~2.09 style files and
+\LaTeXe{} packages and classes is that \LaTeXe{} supports
+\emph{modularity}, in the sense of building files from small
+building-blocks rather than using large single files.
+
+A \LaTeX{} package or class can load a package as follows:
+\begin{verbatim}
+ \RequirePackage[<options>]{<package>}[<date>]
+\end{verbatim}
+For example:
+\begin{verbatim}
+ \RequirePackage{ifthen}[1994/06/01]
+\end{verbatim}
+This command has the same syntax as the author command |\usepackage|.
+It allows packages or classes to use features provided by other
+packages. For example, by loading the |ifthen| package, a package
+writer can use the `if\dots then\dots else\dots' commands provided
+by that package.
+
+A \LaTeX{} class can load one other class as follows:
+\begin{verbatim}
+ \LoadClass[<options>]{<class-name>}[<date>]
+\end{verbatim}
+For example:
+\begin{verbatim}
+ \LoadClass[twocolumn]{article}
+\end{verbatim}
+This command has the same syntax as the author command |\documentclass|.
+It allows classes to be based on the syntax and appearance of another
+class. For example, by loading the |article| class, a class writer
+only has to change the bits of |article| they don't like, rather than
+writing a new class from scratch.
+
+\NEWfeature{1995/12/01}
+The following commands can be used in the common case that you want to
+simply load a class or package file with exactly those options that
+are being used by the current class.
+\begin{verbatim}
+ \LoadClassWithOptions{<class-name>}[<date>]
+ \RequirePackageWithOptions{<package>}[<date>]
+\end{verbatim}
+For example:
+\begin{verbatim}
+ \LoadClassWithOptions{article}
+ \RequirePackageWithOptions{graphics}[1995/12/01]
+\end{verbatim}
+
+\subsection{Declaring options}
+
+\NEWdescription{1998/12/01}
+The other major difference between \LaTeX~2.09 styles and \LaTeXe{}
+packages and classes is in option handling. Packages and classes can
+now declare options and these can be specified by authors; for
+example, the |twocolumn| option is declared by the |article| class.
+Note that the name of an option should contain only those characters
+allowed in a `\LaTeX{} name'; in particular it must not contain any
+control sequences.
+
+An option is declared as follows:
+\begin{verbatim}
+ \DeclareOption{<option>}{<code>}
+\end{verbatim}
+For example, the |dvips| option (slightly simplified)
+to the |graphics| package is implemented as:
+\begin{verbatim}
+ \DeclareOption{dvips}{\input{dvips.def}}
+\end{verbatim}
+This means that when an author writes |\usepackage[dvips]{graphics}|,
+the file |dvips.def| is loaded. As another example, the |a4paper|
+option is declared in the |article| class to set the |\paperheight|
+and |\paperwidth| lengths:
+\begin{verbatim}
+ \DeclareOption{a4paper}{%
+ \setlength{\paperheight}{297mm}%
+ \setlength{\paperwidth}{210mm}%
+ }
+\end{verbatim}
+Sometimes a user will request an option which the class
+or package has not explicitly declared. By default this will produce
+a warning (for classes) or error (for packages); this behaviour
+can be altered as follows:
+\begin{verbatim}
+ \DeclareOption*{<code>}
+\end{verbatim}
+For example, to make the package |fred| produce a warning rather than
+an error for unknown options, you could specify:
+\begin{verbatim}
+ \DeclareOption*{%
+ \PackageWarning{fred}{Unknown option `\CurrentOption'}%
+ }
+\end{verbatim}
+Then, if an author writes |\usepackage[foo]{fred}|, they will get a
+warning \texttt{Package fred Warning: Unknown option `foo'.} As
+another example, the |fontenc| package tries to load a file
+|<ENC>enc.def| whenever the \m{ENC} option is used. This
+can be done by writing:
+\begin{verbatim}
+ \DeclareOption*{%
+ \input{\CurrentOption enc.def}%
+ }
+\end{verbatim}
+\NEWdescription{1998/12/01}
+It is possible to pass options on to another package or class, using
+the command |\PassOptionsToPackage| or |\PassOptionsToClass| (note
+that this is a specialised operation that works only for option
+names). For example, to pass every unknown option on to the |article|
+class, you can use:
+\begin{verbatim}
+ \DeclareOption*{%
+ \PassOptionsToClass{\CurrentOption}{article}%
+ }
+\end{verbatim}
+If you do this then you should make sure you load the class at some
+later point, otherwise the options will never be processed!
+
+So far, we have explained only how to declare options, not how to
+execute them. To process the options with which the file was called,
+you should use:
+\begin{verbatim}
+ \ProcessOptions\relax
+\end{verbatim}
+This executes the \m{code} for each option that was both specified and
+declared (see Section~\ref{Sec:commands.options} for details of how
+this is done).
+
+For example, if the |jane| package file contains:
+\begin{verbatim}
+ \DeclareOption{foo}{\typeout{Saw foo.}}
+ \DeclareOption{baz}{\typeout{Saw baz.}}
+ \DeclareOption*{\typeout{What's \CurrentOption?}}
+ \ProcessOptions\relax
+\end{verbatim}
+and an author writes |\usepackage[foo,bar]{jane}|, then they will see
+the messages \texttt{Saw foo.} and \texttt{What's bar?}
+
+\subsection{A minimal class file}
+
+Most of the work of a class or package is in defining new commands, or
+changing the appearance of documents. This is done in the body of the
+package, using commands such as |\newcommand| or |\setlength|.
+
+\LaTeXe{} provides several new commands to help class and package
+writers; these are described in detail in Section~\ref{Sec:commands}.
+
+There are four things that every class file \emph{must} contain: these
+are a definition of |\normalsize|, values for |\textwidth| and
+|\textheight| and a specification for page-numbering. So a minimal
+document class file\footnote {This class is now in the standard
+distribution, as \texttt{minimal.cls}.} looks like this:
+\begin{verbatim}
+ \NeedsTeXFormat{LaTeX2e}
+ \ProvidesClass{minimal}[1995/10/30 Standard LaTeX minimal class]
+ \renewcommand{\normalsize}{\fontsize{10pt}{12pt}\selectfont}
+ \setlength{\textwidth}{6.5in}
+ \setlength{\textheight}{8in}
+ \pagenumbering{arabic} % needed even though this class will
+ % not show page numbers
+\end{verbatim}
+However, this class file will not support footnotes, marginals,
+floats, etc., nor will it provide any of the 2-letter font commands
+such as |\rm|; thus most classes will contain more than this minimum!
+
+\subsection{Example: a local letter class}
+
+A company may have its own letter class, for setting letters in the
+company style. This section shows a simple implementation of such a
+class, although a real class would need more structure.
+
+The class begins by announcing itself as |neplet.cls|.
+\begin{verbatim}
+ \NeedsTeXFormat{LaTeX2e}
+ \ProvidesClass{neplet}[1995/04/01 NonExistent Press letter class]
+\end{verbatim}
+Then this next bit passes any options on to the |letter| class, which
+is loaded with the |a4paper| option.
+\begin{verbatim}
+ \DeclareOption*{\PassOptionsToClass{\CurrentOption}{letter}}
+ \ProcessOptions\relax
+ \LoadClass[a4paper]{letter}
+\end{verbatim}
+In order to use the company letter head, it redefines the
+|firstpage| page style: this is the page style that is used on
+the first page of letters.
+\begin{verbatim}
+ \renewcommand{\ps@firstpage}{%
+ \renewcommand{\@oddhead}{<letterhead goes here>}%
+ \renewcommand{\@oddfoot}{<letterfoot goes here>}%
+ }
+\end{verbatim}
+And that's it!
+
+\subsection{Example: a newsletter class}
+
+A simple newsletter can be typeset with \LaTeX{}, using a variant of the
+|article| class.
+The class begins by announcing itself as |smplnews.cls|.
+\begin{verbatim}
+ \NeedsTeXFormat{LaTeX2e}
+ \ProvidesClass{smplnews}[1995/04/01 The Simple News newsletter class]
+
+ \newcommand{\headlinecolor}{\normalcolor}
+\end{verbatim}
+It passes most specified options on to the |article| class: apart from
+the |onecolumn| option, which is switched off, and the |green| option,
+which sets the headline in green.
+\begin{verbatim}
+ \DeclareOption{onecolumn}{\OptionNotUsed}
+ \DeclareOption{green}{\renewcommand{\headlinecolor}{\color{green}}}
+
+ \DeclareOption*{\PassOptionsToClass{\CurrentOption}{article}}
+
+ \ProcessOptions\relax
+\end{verbatim}
+It then loads the class |article| with the option |twocolumn|.
+\begin{verbatim}
+ \LoadClass[twocolumn]{article}
+\end{verbatim}
+Since the newsletter is to be printed in colour, it now loads the
+|color| package. The class does not specify a device driver option
+since this should be specified by the user of the |smplnews| class.
+\begin{verbatim}
+ \RequirePackage{color}
+\end{verbatim}
+The class then redefines |\maketitle| to produce the title in 72pt
+Helvetica bold oblique, in the appropriate colour.
+\begin{verbatim}
+ \renewcommand{\maketitle}{%
+ \twocolumn[%
+ \fontsize{72}{80}\fontfamily{phv}\fontseries{b}%
+ \fontshape{sl}\selectfont\headlinecolor
+ \@title
+ ]%
+ }
+\end{verbatim}
+It redefines |\section| and switches off section numbering.
+\begin{verbatim}
+ \renewcommand{\section}{%
+ \@startsection
+ {section}{1}{0pt}{-1.5ex plus -1ex minus -.2ex}%
+ {1ex plus .2ex}{\large\sffamily\slshape\headlinecolor}%
+ }
+
+ \setcounter{secnumdepth}{0}
+\end{verbatim}
+It also sets the three essential things.
+\begin{verbatim}
+ \renewcommand{\normalsize}{\fontsize{9}{10}\selectfont}
+ \setlength{\textwidth}{17.5cm}
+ \setlength{\textheight}{25cm}
+\end{verbatim}
+In practice, a class would need more than this: it would provide
+commands for issue numbers, authors of articles, page styles and so
+on; but this skeleton gives a start. The |ltnews| class file is not
+much more complex than this one.
+
+\section{Commands for class and package writers}
+\label{Sec:commands}
+
+This section describes briefly each of the new commands for class and
+package writers. To find out about other aspects of the new system,
+you should also read \emph{\LaTeXbook}, \emph{\LaTeXcomp} and
+\emph{\usrguide}.
+
+\subsection{Identification}
+
+The first group of commands discussed here are those used
+to identify your class or package file.
+
+\begin{decl}
+|\NeedsTeXFormat| \arg{format-name} \oarg{release-date}
+\end{decl}
+This command tells \TeX{} that this file should be processed using a
+format with name \m{format-name}. You can use the optional argument
+\m{release-date} to further specify the earliest release date of the
+format that is needed. When the release date of the format is older
+than the one specified a warning will be generated. The standard
+\m{format-name} is \texttt{LaTeX2e}. The date, if present, must be in
+the form \textsc{yyyy/mm/dd}.
+
+Example:
+\begin{verbatim}
+ \NeedsTeXFormat{LaTeX2e}[1994/06/01]
+\end{verbatim}
+
+\begin{decl}
+|\ProvidesClass| \arg{class-name} \oarg{release-info} \\
+|\ProvidesPackage| \arg{package-name} \oarg{release-info}
+\end{decl}
+This declares that the current file contains the definitions for the
+document class \m{class-name} or package \m{package-name}.
+
+The optional \m{release-info}, if used, must contain:
+\begin{itemize}
+ \item the release date of
+ this version of the file, in the form \textsc{yyyy/mm/dd};
+\item optionally followed by a space and a short description, possibly
+ including a version number.
+\end{itemize}
+The above syntax must be followed exactly so that this information
+can be used by |\LoadClass| or |\documentclass| (for classes) or
+|\RequirePackage| or |\usepackage| (for packages) to test that the
+release is not too old.
+
+The whole of this \m{release-info} information is displayed by
+|\listfiles| and should therefore not be too long.
+
+Example:
+\begin{verbatim}
+ \ProvidesClass{article}[1994/06/01 v1.0 Standard LaTeX class]
+ \ProvidesPackage{ifthen}[1994/06/01 v1.0 Standard LaTeX package]
+\end{verbatim}
+
+\begin{decl}
+ |\ProvidesFile| \arg{file-name} \oarg{release-info}
+\end{decl}
+This is similar to the two previous commands except that here the full
+filename, including the extension, must be given. It is used for
+declaring any files other than main class and package files.
+
+Example:
+\begin{verbatim}
+ \ProvidesFile{T1enc.def}[1994/06/01 v1.0 Standard LaTeX file]
+\end{verbatim}
+
+Note that the phrase \texttt{Standard LaTeX} \textbf{must not} be used
+in the identification banner of any file other than those in the
+standard \LaTeX{} distribution.
+
+\subsection{Loading files}
+\label{Sec:loadf}
+
+\NEWfeature{1995/12/01}
+This group of commands can be used to create your own document class or
+package by building on existing classes or packages.
+\begin{decl}
+ |\RequirePackage| \oarg{options-list} \arg{package-name}
+ \oarg{release-info}\\
+ |\RequirePackageWithOptions| \arg{package-name}
+ \oarg{release-info}
+\end{decl}
+Packages and classes should use these commands to load other packages.
+
+The use of |\RequirePackage| is the same as the author command
+|\usepackage|.
+
+Examples:
+\begin{verbatim}
+ \RequirePackage{ifthen}[1994/06/01]
+ \RequirePackageWithOptions{graphics}[1995/12/01]
+\end{verbatim}
+
+\begin{decl}
+ |\LoadClass| \oarg{options-list} \arg{class-name}
+ \oarg{release-info}\\
+ |\LoadClassWithOptions| \arg{class-name}
+ \oarg{release-info}
+\end{decl}
+\NEWfeature{1995/12/01}
+These commands are for use \emph{only} in class files, they cannot be
+used in packages files;
+they can be used at most once within a class file.
+
+The use of |\LoadClass| is the same as
+the use of |\documentclass| to load a class file.
+
+Examples:
+\begin{verbatim}
+ \LoadClass{article}[1994/06/01]
+ \LoadClassWithOptions{article}[1995/12/01]
+\end{verbatim}
+
+\NEWfeature{1995/12/01}
+The two |WithOptions| versions simply load the class (or package) file
+with exactly those options that are being used by the current file
+(class or package). See below, in \ref{Sec:opmove}, for further
+discussion of their use.
+
+
+\subsection{Option declaration}
+\label{Sec:commands.options.dec}
+
+\NEWdescription{1998/12/01}
+The following commands deal with the declaration and handling of
+options to document classes and packages. Every option name must be a
+`\LaTeX{} name'.
+
+There are some commands designed especially for use within the
+\m{code} argument of these commands (see below).
+
+\begin{decl}
+ |\DeclareOption| \arg{option-name} \arg{code}
+\end{decl}
+This makes \m{option-name} a `declared option' of the class or package
+in which it is put.
+
+The \m{code} argument contains the code to be executed if that option
+is specified for the class or package; it can contain any valid
+\LaTeXe{} construct.
+
+Example:
+\begin{verbatim}
+ \DeclareOption{twoside}{\@twosidetrue}
+\end{verbatim}
+
+\begin{decl}
+ |\DeclareOption*| \arg{code}
+\end{decl}
+This declares the \m{code} to be executed for every option which is
+specified for, but otherwise not explicitly declared by, the class or
+package; this code is called the `default option code' and it can
+contain any valid \LaTeXe{} construct.
+
+If a class file contains no |\DeclareOption*| then, by default, all
+specified but undeclared options for that class will be silently
+passed to all packages (as will the specified and declared options for
+that class).
+
+If a package file contains no |\DeclareOption*| then, by default, each
+specified but undeclared option for that package will produce an error.
+
+
+\subsection{Commands within option code}
+\label{Sec:within.code}
+
+These two commands can be used only within the \m{code} argument of
+either |\DeclareOption| or |\DeclareOption*|. Other commands commonly
+used within these arguments can be found in the next few subsections.
+
+\begin{decl}
+ |\CurrentOption|
+\end{decl}
+This expands to the name of the current option.
+
+\begin{decl}
+ |\OptionNotUsed|
+\end{decl}
+This causes the current option to
+be added to the list of `unused options'.
+
+\NEWfeature{1995/06/01}
+ You can now include hash marks (\texttt{\#}) within these \m{code}
+ arguments without special treatment (formerly, it had been
+ necessary to double them).
+
+\subsection{Moving options around}
+\label{Sec:opmove}
+
+These two commands are also very useful within the \m{code} argument
+of |\DeclareOption| or |\DeclareOption*|:
+\begin{decl}
+ |\PassOptionsToPackage| \arg{options-list} \arg{package-name}\\
+ |\PassOptionsToClass| \arg{options-list} \arg{class-name}
+\end{decl}
+The command |\PassOptionsToPackage| passes the option names in
+\m{options-list} to package \m{package-name}.
+This means that it adds the \m{option-list} to the
+list of options used by any future |\RequirePackage| or |\usepackage|
+command for package \m{package-name}.
+
+Example:
+\begin{verbatim}
+ \PassOptionsToPackage{foo,bar}{fred}
+ \RequirePackage[baz]{fred}
+\end{verbatim}
+is the same as:
+\begin{verbatim}
+ \RequirePackage[foo,bar,baz]{fred}
+\end{verbatim}
+
+Similarly, |\PassOptionsToClass| may be used in a class file to pass
+options to another class to be loaded with |\LoadClass|.
+
+\NEWdescription{1995/12/01}
+The effects and use of these two commands should be contrasted with
+those of the following two (documented above, in \ref{Sec:loadf}):
+\begin{verbatim}
+ \LoadClassWithOptions
+ \RequirePackageWithOptions
+\end{verbatim}
+The command |\RequirePackageWithOptions| is similar to
+|\RequirePackage|, but it always loads the required package with
+exactly the same option list as that being used by the current class
+or package, rather than with any option explicitly supplied or passed
+on by |\PassOptionsToPackage|.
+
+The main purpose of |\LoadClassWithOptions| is to allow one class to
+simply build on another, for example:
+\begin{verbatim}
+ \LoadClassWithOptions{article}
+\end{verbatim}
+This should be compared with the slightly different construction
+\begin{verbatim}
+ \DeclareOption*{\PassOptionsToClass{\CurrentOption}{article}}
+ \ProcessOptions\relax
+ \LoadClass{article}
+\end{verbatim}
+As used above, the effects are more or less the same, but the first is
+a lot less to type; also the |\LoadClassWithOptions| method runs
+slightly quicker.
+
+If, however, the class declares options of its own then
+the two constructions are different. Compare, for example:
+\begin{verbatim}
+ \DeclareOption{landscape}{\@landscapetrue}
+ \ProcessOptions\relax
+ \LoadClassWithOptions{article}
+\end{verbatim}
+with:
+\begin{verbatim}
+ \DeclareOption{landscape}{\@landscapetrue}
+ \DeclareOption*{\PassOptionsToClass{\CurrentOption}{article}}
+ \ProcessOptions\relax
+ \LoadClass{article}
+\end{verbatim}
+In the first example, the \textsf{article} class will be loaded with
+option |landscape| precisely when the current class is called with
+this option. By contrast, in the second example it will never be
+called with option \texttt{landscape} as in that case \textsf{article}
+is passed options only by the default option handler, but this handler
+is not used for |landscape| because that option is explicitly
+declared.
+
+\subsection{Delaying code}
+\label{Sec:delays}
+
+These first two commands are also intended primarily for use within
+the \m{code} argument of |\DeclareOption| or |\DeclareOption*|.
+
+\begin{decl}
+ |\AtEndOfClass| \arg{code}\\
+ |\AtEndOfPackage| \arg{code}
+\end{decl}
+These commands declare \m{code} that is saved away internally and then
+executed after processing the whole of the current class or package
+file.
+
+Repeated use of these commands is permitted: the code in the
+arguments is stored (and later executed) in the order of their
+declarations.
+
+\begin{decl}
+ |\AtBeginDocument| \arg{code}\\
+ |\AtEndDocument| \arg{code}
+\end{decl}
+These commands declare \m{code} to be saved internally and executed
+while \LaTeX{} is executing |\begin{document}| or |\end{document}|.
+
+The \m{code} specified in the argument to |\AtBeginDocument| is
+executed near the end of the |\begin{document}| code, \emph{after} the
+font selection tables have been set up. It is therefore a useful
+place to put code which needs to be executed after everything has been
+prepared for typesetting and when the normal font for the document is
+the current font.
+
+\NEWdescription{1995/12/01}
+The |\AtBeginDocument| hook should not be used for code that does any
+typesetting since the typeset result would be unpredictable.
+
+The \m{code} specified in the argument to |\AtEndDocument| is
+executed at the beginning of the |\end{document}| code,
+\emph{before} the final page is finished and before any leftover
+floating environments are processed. If some of the \m{code} is to be
+executed after these two processes, you should include a |\clearpage|
+at the appropriate point in \m{code}.
+
+Repeated use of these commands is permitted: the code in the
+arguments is stored (and later executed) in the order of their
+declarations.
+
+\begin{decl}[1994/12/01]
+ |\AtBeginDvi| \arg{specials}
+\end{decl}
+These commands save in a box register things which are written to the
+|.dvi| file at the beginning of the `shipout' of the first page of the
+document.
+
+This should not be used for anything that will add any typeset
+material to the |.dvi| file.
+
+Repeated use of this command is permitted.
+
+
+\subsection{Option processing}
+\label{Sec:commands.options}
+
+\begin{decl}
+ |\ProcessOptions|
+\end{decl}
+This command executes the \m{code} for each selected option.
+
+We shall first describe how |\ProcessOptions| works in a package file,
+and then how this differs in a class file.
+
+To understand in detail what |\ProcessOptions| does in a package file,
+you have to know the difference between \emph{local} and \emph{global}
+options.
+\begin{itemize}
+\item \textbf{Local options} are those which have been explicitly
+ specified for this particular package in the \m{options} argument of
+ any of these:
+\begin{quote}
+ |\PassOptionsToPackage{<options>}| \ |\usepackage[<options>]|\\
+ |\RequirePackage[<options>]|
+\end{quote}
+\item \textbf{Global options} are any other options that are specified
+ by the author in the \m{options} argument of
+ |\documentclass[<options>]|.
+\end{itemize}
+For example, suppose that a document begins:
+\begin{verbatim}
+ \documentclass[german,twocolumn]{article}
+ \usepackage{gerhardt}
+\end{verbatim}
+whilst package |gerhardt| calls package |fred| with:
+\begin{verbatim}
+ \PassOptionsToPackage{german,dvips,a4paper}{fred}
+ \RequirePackage[errorshow]{fred}
+\end{verbatim}
+then:
+\begin{itemize}
+\item |fred|'s local options are |german|, |dvips|, |a4paper|
+ and |errorshow|;
+\item |fred|'s only global option is |twocolumn|.
+\end{itemize}
+
+When |\ProcessOptions| is called, the following happen.
+\begin{itemize}
+\item \emph{First}, for each option so far declared in |fred.sty|
+ by |\DeclareOption|, it looks to see if that option is either a
+ global or a local option for |fred|: if it is then the corresponding
+ code is executed.
+
+ This is done in the order in which these options
+ were declared in |fred.sty|.
+\item \emph{Then}, for each remaining \emph{local} option, the command
+ |\ds@<option>| is executed if it has been defined somewhere (other
+ than by a |\DeclareOption|); otherwise, the `default option code' is
+ executed. If no default option code has been declared then an error
+ message is produced.
+
+ This is done in the order in which these
+ options were specified.
+\end{itemize}
+Throughout this process, the system ensures that the code declared for
+an option is executed at most once.
+
+Returning to the example, if |fred.sty| contains:
+\begin{verbatim}
+ \DeclareOption{dvips}{\typeout{DVIPS}}
+ \DeclareOption{german}{\typeout{GERMAN}}
+ \DeclareOption{french}{\typeout{FRENCH}}
+ \DeclareOption*{\PackageWarning{fred}{Unknown `\CurrentOption'}}
+ \ProcessOptions\relax
+\end{verbatim}
+then the result of processing this document will be:
+\begin{verbatim}
+ DVIPS
+ GERMAN
+ Package fred Warning: Unknown `a4paper'.
+ Package fred Warning: Unknown `errorshow'.
+\end{verbatim}
+Note the following:
+
+\begin{itemize}
+\item the code for the |dvips| option is executed before that for the
+ |german| option, because that is the order in which they are declared
+ in |fred.sty|;
+\item the code for the |german| option is executed only once, when the
+ declared options are being processed;
+\item the |a4paper| and |errorshow| options produce the warning from
+ the code declared by |\DeclareOption*| (in the order in which they
+ were specified), whilst the |twocolumn| option does not: this is
+ because |twocolumn| is a global option.
+\end{itemize}
+
+In a class file, |\ProcessOptions| works in the same way, except
+that: \emph{all} options are local; and the default value for
+|\DeclareOption*| is |\OptionNotUsed| rather than an error.
+
+\NEWdescription{1995/12/01}
+Note that, because |\ProcessOptions| has a |*|-form, it is wise to
+follow the non-star form with |\relax|, as in the previous examples,
+since this prevents unnecessary look ahead and possibly misleading
+error messages being issued.
+
+\begin{decl}
+ |\ProcessOptions*| \\
+ |\@options|
+\end{decl}
+This is like |\ProcessOptions| but it executes the options in the
+order specified in the calling commands, rather than in the order of
+declaration in the class or package. For a package this means that the
+global options are processed first.
+
+The |\@options| command from \LaTeX~2.09 has been made equivalent to
+this in order to ease the task of updating old document styles to
+\LaTeXe{} class files.
+
+\begin{decl}
+ |\ExecuteOptions| \arg{options-list}
+\end{decl}
+
+For each option in the \m{options-list}, in order,
+this command simply executes the command
+|\ds@<option>| (if this command is not defined, then that option is
+silently ignored).
+
+It can be used to provide a `default option list' just before
+|\ProcessOptions|. For example, suppose that in a class file you want
+to set up the default design to be: two-sided printing; 11pt fonts;
+in two columns. Then it could specify:
+\begin{verbatim}
+ \ExecuteOptions{11pt,twoside,twocolumn}
+\end{verbatim}
+
+
+\subsection{Safe file commands}
+
+These commands deal with file input; they ensure that the non-existence
+of a requested file can be handled in a user-friendly way.
+
+\begin{decl}
+|\IfFileExists| \arg{file-name} \arg{true} \arg{false}
+\end{decl}
+If the file exists then the code specified in \m{true} is
+executed.
+
+If the file does not exist then the code specified in \m{false} is
+executed.
+
+This command does \emph{not} input the file.
+
+\begin{decl}
+ |\InputIfFileExists| \arg{file-name} \arg{true} \arg{false}
+\end{decl}
+This inputs the file \m{file-name} if it exists and, immediately
+before the input, the code specified in \m{true} is executed.
+
+If the file does not exist then the code specified in \m{false} is
+executed.
+
+It is implemented using |\IfFileExists|.
+
+
+\subsection{Reporting errors, etc}
+
+These commands should be used by third party classes and packages to
+report errors, or to provide information to authors.
+
+\begin{decl}
+ |\ClassError| \arg{class-name} \arg{error-text} \arg{help-text}\\
+ |\PackageError| \arg{package-name} \arg{error-text} \arg{help-text}
+\end{decl}
+These produce an error message. The \m{error-text} is displayed and the
+|?| error prompt is shown. If the user types |h|, they will be shown
+the \m{help-text}.
+
+Within the \m{error-text} and \m{help-text}: |\protect| can be used to
+stop a command from expanding; |\MessageBreak| causes a line-break;
+and |\space| prints a space.
+
+Note that the \m{error-text} will have a full stop added to it, so do
+not put one into the argument.
+
+For example:
+\begin{verbatim}
+ \newcommand{\foo}{FOO}
+ \PackageError{ethel}{%
+ Your hovercraft is full of eels,\MessageBreak
+ and \protect\foo\space is \foo
+ }{%
+ Oh dear! Something's gone wrong.\MessageBreak
+ \space \space Try typing \space <<return>>
+ \space to proceed, ignoring \protect\foo.
+ }
+\end{verbatim}
+produces this display:
+\begin{verbatim}
+ ! Package ethel Error: Your hovercraft is full of eels,
+ (ethel) and \foo is FOO.
+
+ See the ethel package documentation for explanation.
+\end{verbatim}
+If the user types |h|, this will be shown:
+\begin{verbatim}
+ Oh dear! Something's gone wrong.
+ Try typing <<return>> to proceed, ignoring \foo.
+\end{verbatim}
+
+\begin{decl}
+ |\ClassWarning| \arg{class-name} \arg{warning-text}\\
+ |\PackageWarning| \arg{package-name} \arg{warning-text}\\
+ |\ClassWarningNoLine| \arg{class-name} \arg{warning-text}\\
+ |\PackageWarningNoLine| \arg{package-name} \arg{warning-text}\\
+ |\ClassInfo| \arg{class-name} \arg{info-text}\\
+ |\PackageInfo| \arg{package-name} \arg{info-text}
+\end{decl}
+The four |Warning| commands are similar to the error commands, except
+that they produce only a warning on the screen, with no error prompt.
+
+The first two, |Warning| versions, also show the line number where the
+warning occurred, whilst the second two, |WarningNoLine| versions, do
+not.
+
+The two |Info| commands are similar except that they log the
+information only in the transcript file, including the line number.
+There are no |NoLine| versions of these two.
+
+Within the \m{warning-text} and \m{info-text}: |\protect| can be used to
+stop a command from expanding; |\MessageBreak| causes a line-break;
+and |\space| prints a space.
+Also, these should not end with a full stop as one is
+automatically added.
+
+
+\subsection{Defining commands}
+\label{Sec:commands.define}
+
+\LaTeXe{} provides some extra methods of (re)defining commands that are
+intended for use in class and package files.
+
+\NEWfeature{1994/12/01}
+The \texttt{*}-forms of these commands should be used to define
+commands that are not, in \TeX{} terms, long. This can be useful for
+error-trapping with commands whose arguments are not intended to
+contain whole paragraphs of text.
+
+\begin{decl}
+ |\DeclareRobustCommand| \arg{cmd} \oarg{num} \oarg{default}
+ \arg{definition}\\
+ |\DeclareRobustCommand*| \arg{cmd} \oarg{num} \oarg{default}
+ \arg{definition}
+\end{decl}
+This command takes the same arguments as |\newcommand| but it declares
+a robust command, even if some code within the \m{definition} is
+fragile. You can use this command to define new robust commands, or
+to redefine existing commands and make them robust. A log is put into
+the transcript file if a command is redefined.
+
+For example, if |\seq| is defined as follows:
+\begin{verbatim}
+ \DeclareRobustCommand{\seq}[2][n]{%
+ \ifmmode
+ #1_{1}\ldots#1_{#2}%
+ \else
+ \PackageWarning{fred}{You can't use \protect\seq\space in text}%
+ \fi
+ }
+\end{verbatim}
+Then the command |\seq| can be used in moving arguments, even though
+|\ifmmode| cannot, for example:
+\begin{verbatim}
+ \section{Stuff about sequences $\seq{x}$}
+\end{verbatim}
+
+Note also that there is no need to put a |\relax| before the
+|\ifmmode| at the beginning of the definition; this is because the
+protection given by this |\relax| against expansion at the wrong time
+will be provided internally.
+
+\begin{decl}
+ |\CheckCommand| \arg{cmd} \oarg{num} \oarg{default}
+ \arg{definition}\\
+ |\CheckCommand*| \arg{cmd} \oarg{num} \oarg{default}
+ \arg{definition}
+\end{decl}
+This takes the same arguments as |\newcommand| but, rather than define
+\m{cmd}, it just checks that the current definition of \m{cmd} is
+exactly as given by \m{definition}. An error is raised if these
+definitions differ.
+
+This command is useful for checking the state of the system before
+your package starts altering the definitions of commands. It allows
+you to check, in particular, that no other package has redefined the
+same command.
+
+\subsection{Moving arguments}
+
+\NEWdescription{1994/12/01}
+The setting of protect whilst processing (i.e.~moving) moving arguments
+has been reimplemented, as has the method of writing information from
+the |.aux| file to other files such as the |.toc| file. Details can
+be found in the file |ltdefns.dtx|.
+
+We hope that these changes will not affect many packages.
+
+\section{Miscellaneous commands, etc}
+\label{Sec:commands.misc}
+
+\subsection{Layout parameters}
+
+\begin{decl}
+|\paperheight|\\
+|\paperwidth|
+\end{decl}
+These two parameters are usually set by the class to be the size of
+the paper being used. This should be actual paper size, unlike
+|\textwidth| and |\textheight| which are the size of the main text
+body within the margins.
+
+
+\subsection{Case changing}
+\label{sec:case}
+
+\begin{decl}
+ |\MakeUppercase| \arg{text} \\
+ |\MakeLowercase| \arg{text}
+\end{decl}
+
+\NEWfeature{1995/06/01}
+\TeX{} provides two primitives |\uppercase| and |\lowercase| for
+changing the case of text. These are sometimes used in document
+classes, for example to set information in running heads in all
+capitals.
+
+Unfortunately, these \TeX{} primitives do not change the case of
+characters accessed by commands like |\ae| or |\aa|. To overcome this
+problem, \LaTeX{} provides two new commands |\MakeUppercase| and
+|\MakeLowercase| to do this.
+
+For example:
+\begin{quotation}
+\begin{tabular}{rl}
+ |\uppercase{aBcD\ae\AA\ss\OE}| & \uppercase{aBcD\ae\AA\ss\OE}\\
+ |\lowercase{aBcD\ae\AA\ss\OE}| & \lowercase{aBcD\ae\AA\ss\OE}\\
+ |\MakeUppercase{aBcD\ae\AA\ss\OE}| &
+ \MakeUppercase{aBcD\ae\AA\ss\OE}\\
+ |\MakeLowercase{aBcD\ae\AA\ss\OE}| & \MakeLowercase{aBcD\ae\AA\ss\OE}
+\end{tabular}
+\end{quotation}
+
+The commands |\MakeUppercase| and |\MakeLowercase| themselves are
+robust, but they have moving arguments.
+
+The commands use the \TeX{} primitives |\uppercase| and |\lowercase|,
+and so have a number of unexpected `features'. In particular, they
+change the case of everything (except characters in the names of
+control-sequences) in their text argument: this includes mathematics,
+environment names, and label names.
+
+For example:
+\begin{verbatim}
+ \MakeUppercase{$x+y$ in \ref{foo}}
+\end{verbatim}
+produces $X+Y$ and the warning:
+\begin{verbatim}
+ LaTeX Warning: Reference `FOO' on page ... undefined on ...
+\end{verbatim}
+In the long run, we would like to use all-caps fonts rather than any
+command like |\MakeUppercase| but this is not possible at the moment
+because such fonts do not exist.
+
+\NEWdescription{1995/12/01}
+In order that upper/lower-casing will work reasonably well, and in
+order to provide any correct hyphenation, \LaTeXe{} \emph{must} use,
+throughout a document, the same fixed table for changing case.
+The table used is designed for the font encoding |T1|; this works well
+with the standard \TeX{} fonts for all Latin alphabets but will cause
+problems when using other alphabets.
+
+\subsection{The `openany' option in the `book' class}
+
+\NEWdescription{1996/06/01}
+The |openany| option allows chapter and similar openings to
+occur on left hand pages. Previously this option affected only
+|\chapter| and |\backmatter|. It now also affects
+|\part|, |\frontmatter| and |\mainmatter|.
+
+\subsection{Better user-defined math display environments}
+
+\begin{decl}
+ |\ignorespacesafterend|
+\end{decl}
+
+\NEWfeature{1996/12/01}
+\NEWdescription{2003/12/01}
+Suppose that you want to define an environment for displaying text
+that is numbered as an equation. A straightforward way to do this is
+as follows:
+\begin{verbatim}
+ \newenvironment{texteqn}
+ {\begin{equation}
+ \begin{minipage}{0.9\linewidth}}
+ {\end{minipage}
+ \end{equation}}
+\end{verbatim}
+However, if you have tried this then you will probably have noticed
+that it does not work perfectly when used in the middle of a paragraph
+because an inter-word space appears at the beginning of the first
+line after the environment.
+
+There is now an extra command (with a very long name) available that
+you can use to avoid this problem; it should be inserted as shown here:
+\begin{verbatim}
+ \newenvironment{texteqn}
+ {\begin{equation}
+ \begin{minipage}{0.9\linewidth}}
+ {\end{minipage}
+ \end{equation}
+ \ignorespacesafterend}
+\end{verbatim}
+
+This command may also have other uses.
+
+\subsection{Normalising spacing}
+
+\begin{decl}
+ |\normalsfcodes|
+\end{decl}
+
+\NEWfeature{1997/06/01}
+This command should be used to restore the normal settings of the
+parameters that affect spacing between words, sentences, etc.
+
+An important use of this feature is to correct a problem, reported by
+Donald Arseneau, that punctuation in page headers has always (in all
+known \TeX{} formats) been potentially wrong whenever a page break
+happens while a local setting of the space codes is in effect. These
+space codes are changed by, for example, the command
+\verb|\frenchspacing|) and the \textsf{verbatim} environment.
+
+It is normally given the correct definition automatically in
+|\begin{document}| and so need not be explicitly set; however, if it
+is explicitly made nonempty in a class file then automatic
+default setting will be over-ridden.
+
+
+\section{Upgrading \LaTeX~2.09 classes and packages}
+\label{Sec:upgrade}
+
+This section describes the changes you may need to make when you
+upgrade an existing \LaTeX{} style to a package or class but we shall
+start in optimistic mode.
+
+Many existing style files will run with \LaTeXe{} without any
+modification to the file itself. When everything is running OK,
+please put a note in the newly created package or class file to record
+that it runs with the new standard \LaTeX{}; then distribute it to
+your users.
+
+\subsection{Try it first!}
+\label{Sec:try-it}
+
+The first thing you should do is to test your style in `compatibility
+mode'. The only change you need to make in order to do this is,
+possibly, to change the extension of the file to |.cls|: you should
+make this change only if your file was used as a main document style.
+Now, without any other modifications, run \LaTeXe{} on a document that
+uses your file. This assumes that you have a suitable collection of
+files that tests all the functionality provided by your style file.
+(If you haven't, now is the time to make one!)
+
+You now need to change the test document files so that they are
+\LaTeXe{} documents: see \emph{\usrguide} for details of how to do
+this and then try them again. You have now tried the test documents
+in both \LaTeXe{} native mode and \LaTeX~2.09 compatibility mode.
+
+\subsection{Troubleshooting}
+\label{Sec:trouble}
+
+If your file does not work with \LaTeXe{}, there are two likely
+reasons.
+\begin{itemize}
+\item \LaTeX{} now has a robust, well-defined designer's interface for
+ selecting fonts, which is very different from the \LaTeX~2.09
+ internals.
+\item Your style file may have used some \LaTeX~2.09 internal commands
+ which have changed, or which have been removed.
+\end{itemize}
+
+When you are debugging your file, you will probably need more
+information than is normally displayed by \LaTeXe. This is achieved
+by resetting the counter |errorcontextlines| from its default value of
+$-1$ to a much higher value, e.g.~999.
+
+\subsection{Accommodating compatibility mode}
+
+Sometimes an existing collection of \LaTeX~2.09 documents makes it
+inconvenient or impossible to abandon the old commands entirely.
+If this is the case, then it is possible to accommodate both conventions
+by making special provision for documents processed in compatibility
+mode.
+
+\begin{decl}
+|\if@compatibility|
+\end{decl}
+This switch is set when a document begins with |\documentstyle| rather
+than |\documentclass|. Appropriate code can be supplied for either
+condition, as follows:
+\begin{verbatim}
+ \if@compatibility
+ <code emulating LaTeX 2.09 behavior>
+ \else
+ <code suitable for LaTeX2e>
+ \fi
+\end{verbatim}
+
+
+\subsection{Font commands}
+
+Some font and size commands are now defined by the document class
+rather than by the \LaTeX{} kernel. If you are upgrading a
+\LaTeX~2.09 document style to a class that does not load one of the
+standard classes, then you will probably need to add definitions for
+these commands.
+
+\begin{decl}
+ |\rm| |\sf| |\tt| |\bf| |\it| |\sl| |\sc|
+\end{decl}
+None of these short-form font selection commands are defined in the
+\LaTeXe{} kernel. They are defined by all the standard class files.
+
+If you want to define them in your class file, there are several
+reasonable ways to do this.
+
+One possible definition is:
+\begin{verbatim}
+ \newcommand{\rm}{\rmfamily}
+ ...
+ \newcommand{\sc}{\scshape}
+\end{verbatim}
+This would make the font commands orthogonal; for example
+|{\bf\it text}| would produce bold italic, thus: \textbf{\textit{text}}.
+It will also make them produce an error if used in math mode.
+
+Another possible definition is:
+\begin{verbatim}
+ \DeclareOldFontCommand{\rm}{\rmfamily}{\mathrm}
+ ...
+ \DeclareOldFontCommand{\sc}{\scshape}{\mathsc}
+\end{verbatim}
+This will make |\rm| act like |\rmfamily| in text mode (see above) and
+it will make |\rm| select the |\mathrm| math alphabet in math mode.
+
+Thus |${\rm math} = X + 1$| will produce `${\rm math} = X + 1$'.
+
+If you do not want font selection to be orthogonal then you can
+follow the standard classes and define:
+\begin{verbatim}
+ \DeclareOldFontCommand{\rm}{\normalfont\rmfamily}{\mathrm}
+ ...
+ \DeclareOldFontCommand{\sc}{\normalfont\scshape}{\mathsc}
+\end{verbatim}
+This means, for example, that |{\bf\it text}| will produce medium
+weight (rather than bold) italic, thus: \textit{text}.
+
+\begin{decl}
+ |\normalsize| \\
+ |\@normalsize|
+\end{decl}
+The command |\@normalsize| is retained for compatibility with
+\LaTeX~2.09 packages which may have used its value; but redefining it
+in a class file will have no effect since it is always reset to have
+the same meaning as |\normalsize|.
+
+This means that classes \emph{must} now redefine |\normalsize| rather
+than redefining |\@normalsize|; for example (a rather incomplete one):
+\begin{verbatim}
+ \renewcommand{\normalsize}{\fontsize{10}{12}\selectfont}
+\end{verbatim}
+Note that |\normalsize| is defined by the \LaTeX{} kernel to be an
+error message.
+
+\begin{decl}
+ |\tiny| |\footnotesize| |\small| |\large|\\
+ |\Large| |\LARGE| |\huge| |\Huge|
+\end{decl}
+None of these other `standard' size-changing commands are defined in
+the kernel: each needs to be defined in a class file if you need it.
+They are all defined by the standard classes.
+
+This means you should use |\renewcommand| for |\normalsize| and
+|\newcommand| for the other size-changing commands.
+
+
+\subsection{Obsolete commands}
+
+Some packages will not work with \LaTeXe{}, normally because they relied
+on an internal \LaTeX{} command which was never supported and has now
+changed, or been removed.
+
+In many cases there will now be a robust, high-level means of
+achieving what previously required low-level commands. Please consult
+Section~\ref{Sec:commands} to see if you can now use the \LaTeXe{}
+class and package writers commands.
+
+Also, of course, if your package or class redefined any of the kernel
+commands (i.e.~those defined in the files |latex.tex|, |slitex.tex|,
+|lfonts.tex|, |sfonts.tex|) then you will need to check it very
+carefully against the new kernel in case the implementation has
+changed or the command no longer exists in the \LaTeX2e{} kernel.
+
+Too many of the internal commands of \LaTeX~2.09 have been
+re-implemented or removed to be able to list them all here. You must
+check any that you have used or changed.
+
+We shall, however, list some of the more important commands which are
+no longer supported.
+
+\begin{decl}
+ |\tenrm| |\elvrm| |\twlrm| \dots\\
+ |\tenbf| |\elvbf| |\twlbf| \dots\\
+ |\tensf| |\elvsf| |\twlsf| \dots\\
+ \qquad$\vdots$
+\end{decl}
+The (approximately) seventy internal commands of this form are no longer
+defined. If your class or package uses them then \emph{please}
+replace them with new font commands described in \emph{\fntguide}.
+
+For example, the command |\twlsf| should be replaced by:
+\begin{verbatim}
+ \fontsize{12}{14}\normalfont\sffamily\selectfont
+\end{verbatim}
+
+Another possibility is to use the |rawfonts| package, described in
+\emph{\usrguide}.
+
+Also, remember that many of the fonts preloaded by \LaTeX~2.09
+are no longer preloaded.
+
+\begin{decl}
+ |\vpt| |\vipt| |\viipt| \dots
+\end{decl}
+These were the internal size-selecting commands in \LaTeX~2.09.
+(They can still be used in \LaTeX~2.09 compatibility mode.)
+Please use the command |\fontsize| instead: see \emph{\fntguide} for
+details.
+
+For example, |\vpt| should be replaced by:
+\begin{verbatim}
+ \fontsize{5}{6}\normalfont\selectfont
+\end{verbatim}
+
+\begin{decl}
+ |\prm|, |\pbf|, |\ppounds|, |\pLaTeX| \dots
+\end{decl}
+\LaTeX~2.09 used several commands beginning with |\p| in order to
+provide `protected' commands. For example, |\LaTeX| was defined to be
+|\protect\pLaTeX|, and |\pLaTeX| was defined to produce the \LaTeX{}
+logo. This made |\LaTeX| robust, even though |\pLaTeX| was not.
+
+These commands have now been reimplemented using
+|\DeclareRobustCommand|
+(described in Section~\ref{Sec:commands.define}).
+If your package redefined one of the |\p|-commands then you must
+remove the redefinition and use |\DeclareRobustCommand| to redefine the
+non-|\p| command.
+
+\begin{decl}
+|\footheight|\\
+|\@maxsep|\\
+|\@dblmaxsep|
+\end{decl}
+These parameters are not used by \LaTeXe{} so they have been removed,
+except in \LaTeX~2.09 compatibility mode. Classes should no longer
+set them.

\section{Introduction}
-This document is an introduction to writing classes and packages for
-\LaTeX{}, with special attention given to upgrading existing
-\LaTeX~2.09 packages to \LaTeXe{}. The latter subject is also
-covered in an article by Johannes Braams published in TUGboat~15.3.
-
-\subsection{Writing classes and packages for \LaTeXe}
-
-\LaTeX{} is a document preparation system that enables the document
-writer to concentrate on the contents of their text, without bothering
-too much about the formatting of it. For example, chapters are
-indicated by |\chapter{<title>}| rather than by selecting 18pt bold.
-
-The file that contains the information about how to turn logical
-structure (like `|\chapter|') into formatting (like `18pt bold ragged
-right') is a \emph{document class}. In addition, some features (such
-as colour or included graphics) are independent of the document class
-and these are contained in \emph{packages}.
+\LaTeXe{} was released in 1994 and added a number of then-new concepts to
+\LaTeX{}. For package and class authors, these are described in
+\texttt{clsguide-historic}, which has largely remained unchanged. Since then,
+the \LaTeX{} team have worked on a number of ideas, firstly a programming
+language for \LaTeX{} (L3 programming layer) and then a range of tools for
+authors which build on that language. Here, we describe the current, stable set
+of tools provided by the \LaTeX{} kernel for package and class developers. We
+assume familiarity with general \LaTeX{} usage as a document author, and that
+the material here is read in conjunction with \texttt{usrguide}, which provides
+information for general \LaTeX{} users on up-to-date approaches to creating
+commands, etc.
-One of the largest differences between \LaTeX~2.09 and \LaTeXe{} is in
-the commands used to write packages and classes. In \LaTeX~2.09,
-there was very little support for writing |.sty| files, and so writers
-had to resort to using low-level commands.
+\section{Writing classes and packages}
+\label{Sec:writing}
-\LaTeXe{} provides high-level commands for structuring packages.
-It is also much easier to build classes and packages on top of each
-other, for example writing a local technical report class |cetechr|

+This section covers some general points concerned with writing
+\LaTeX{} classes and packages.
-\subsection{Overview}
+\subsection{Is it a class or a package?}
+\label{Sec:classorpkg}
-This document contains an overview of how to write classes and
-packages for \LaTeX{}. It does \emph{not} introduce all of the
-commands necessary to write packages: these can be found in either
-\emph{\LaTeXbook} or \emph{\LaTeXcomp}. But it does describe the new
-commands for structuring classes and packages.
+The first thing to do when you want to put some new \LaTeX{} commands
+in a file is to decide whether it should be a \emph{document class} or a
+\emph{package}. The rule of thumb is:
+\begin{quote}
+ If the commands could be used with any document class, then make
+ them a package; and if not, then make them a class.
+\end{quote}
-\begin{description}
+There are two major types of class: those like |article|, |report| or
+|letter|, which are free-standing; and those which are extensions or
+variations of other classes---for example, the |proc| document class,
+which is built on the |article| document class.
-\item[Section~\ref{Sec:general}] contains some general advice about
- writing classes and packages. It describes the difference between
- classes and packages, the command naming conventions, the use of
- |doc| and |docstrip|, how \TeX's primitive file and box commands
- interact with \LaTeX{}. It also contains some hints about general
- \LaTeX{} style.
+Thus, a company might have a local |ownlet| class for printing letters
+with their own headed note-paper. Such a class would build on top of
+the existing |letter| class but it cannot be used with any other
+document class, so we have |ownlet.cls| rather than |ownlet.sty|.
-\item[Section~\ref{Sec:structure}] describes the structure of classes
- and packages. This includes building classes and packages on top of
- other classes and packages, declaring options and declaring
- commands. It also contains example classes.
+The |graphics| package, in contrast, provides commands for including
+images into a \LaTeX{} document. Since these commands can be used
+with any document class, we have |graphics.sty| rather than
+|graphics.cls|.
-\item[Section~\ref{Sec:commands}] lists the new class and package
- commands.
+\subsection{Using `docstrip' and `doc'}
- \item[Section~\ref{Sec:upgrade}] gives detailed advice on how to
- upgrade existing \LaTeX~2.09 classes and packages to \LaTeXe{}.
+If you are going to write a large class or package for \LaTeX{} then
+you should consider using the |doc| software which comes with
+\LaTeX{}.
+\LaTeX{} classes and packages written using this can be
+processed in two ways: they can be run through \LaTeX{}, to produce
+documentation; and they can be processed with |docstrip|, to produce
+the |.cls| or |.sty| file.
-\end{description}
+The |doc| software can automatically generate indexes of definitions,
+indexes of command use, and change-log lists. It is very useful for
+maintaining and documenting large \TeX{} sources.

-\subsection{Old versions}
-
-If you are upgrading an existing \LaTeX~2.09 style file then we
-recommend freezing the 2.09 version and no longer maintaining it.
-Experience with the various dialects of \LaTeX{} which existed in the
-early 1990's suggests that maintaining packages for different versions
-of \LaTeX{} is almost impossible. It will, of course, be necessary
-for some organisations to maintain both versions in parallel for some
-time but this is not essential for those packages and classes
-supported by individuals: they should support only the new standard
-\LaTeXe{}, not obsolete versions of \LaTeX{}.

-\subsection{Is it a class or a package?}
-\label{Sec:classorpkg}
-
-The first thing to do when you want to put some new \LaTeX{} commands
-in a file is to decide whether it should be a \emph{document class} or a
-\emph{package}. The rule of thumb is:
-\begin{quote}
- If the commands could be used with any document class, then make

\subsection{Command names}
-\LaTeX{} has three types of command.
+Prior to the introduction of the L3~programming layer described in the next
+section, \LaTeX{} had three types of command.
There are the author commands, such as |\section|, |\emph| and
|\times|: most of these have short names, all in lower case.
@@ -289,117 +190,97 @@ However, this rule of thumb is still useful: if a command has |@| in
its name then it is not part of the supported \LaTeX{} language---and
its behaviour may change in future releases! If a command is
mixed-case, or is described in \emph{\LaTeXbook}, then you can rely on
-future releases of \LaTeXe{} supporting the command.
-
-\subsection{Box commands and colour}
-\label{Sec:colour}
-
-Even if you do not intend to use colour in your own documents, by
-taking note of the points in this section you can ensure that your
-class or package is compatible with the |color| package. This may
-benefit people using your class or package who have access to colour
-printers.
-
-The simplest way to ensure `colour safety' is to always use \LaTeX{}
-box commands rather than \TeX{} primitives, that is use |\sbox| rather
-than |\setbox|, |\mbox| rather than |\hbox| and |\parbox| or
-the |minipage| environment rather than |\vbox|.
-The \LaTeX{} box commands have new options which mean that they are now
-as powerful as the \TeX{} primitives.
-
-As an example of what can go wrong, consider that in
-|{\ttfamily <text>}|
-the font is restored just \emph{before} the |}|, whereas in the
-similar looking construction
-|{\color{green} <text>}|
-the colour is restored just \emph{after} the final |}|. Normally this
-distinction does not matter at all; but consider a primitive \TeX{}
-box assignment such as:
+future releases of \LaTeX{} supporting the command.
+
+\subsection{Programming support}
+
+As noted in the introduction, the \LaTeX{} kernel today loads dedicated support
+from programming, here referred to as the L3 programming layer but also often
+called \pkg{expl3}. Details of the general approach taken by the L3
+programming layer are given in the document \texttt{expl3}, while a reference
+for all current code interfaces is available as \texttt{interface3}. This layer
+contains two types of command: a documented set of commands making up the API
+and a large number of private internal commands. The latter all start with two
+underscores and should not be used outside of the code module which defines
+them. This more structured approach means that using the L3 programming layer
+does not suffer from the somewhat fluid situation mentioned above with
+`\texttt{@} commands'.
+
+We do not cover the detail of using the L3 programming layer here. A good
+introduction to the approach is provided at
+\url{https://www.alanshawn.com/latex3-tutorial/}.
+
+\subsection{Box commands and color}
+\label{Sec:color}
+
+Even if you do not intend to use color in your own documents, by taking note of
+the points in this section you can ensure that your class or package is
+compatible with the |color| package. This may benefit people using your class
+or package and wish to use color.
+
+The simplest way to ensure `color safety' is to always use \LaTeX{} box
+commands rather than \TeX{} primitives, that is use |\sbox| rather than
+|\setbox|, |\mbox| rather than |\hbox| and |\parbox| or the |minipage|
+environment rather than |\vbox|. The \LaTeX{} box commands have new options
+which mean that they are now as powerful as the \TeX{} primitives.
+
+As an example of what can go wrong, consider that in |{\ttfamily <text>}| the
+font is restored just \emph{before} the |}|, whereas in the similar looking
+construction |{\color{green} <text>}| the color is restored just \emph{after}
+the final |}|. Normally this distinction does not matter at all; but consider a
+primitive \TeX{} box assignment such as:
\begin{verbatim}
\setbox0=\hbox{\color{green} <text>}
\end{verbatim}
-Now the colour-restore occurs after the |}| and so is \emph{not}
-stored in the box. Exactly what bad effects this can have depends on
-how colour is implemented: it can range from getting the wrong
-colours in the rest of the document, to causing errors in the
-dvi-driver used to print the document.
-
-Also of interest is the command |\normalcolor|. This is
-normally just |\relax| (i.e., does nothing)
-but you can use it rather like |\normalfont| to
-set regions of the page such as captions or section headings to the
-`main document colour'.
-
-
-\subsection{Defining text and math characters}
-\label{Sec:chars}
-
-Because \LaTeXe{} supports different encodings, definitions of commands
-for producing symbols, accents, composite glyphs, etc.\ must be
-defined using the commands provided for this purpose and described in
-\emph{\fntguide}. This part of the system is still under development
-so such tasks should be undertaken with great caution.
-
-Also, |\DeclareRobustCommand| should be used for encoding-independent
-commands of this type.
-
-Note that it is no longer possible to refer to the math font set-up
-outside math mode: for example, neither |\textfont 1| nor
-|\scriptfont 2| are guaranteed to be defined in other modes.
+Now the color-restore occurs after the |}| and so is \emph{not} stored in the
+box. Exactly what bad effects this can have depends on how color is

-|\input baz.sty| then the user will get a warning:
+If the package |foo.sty| loads the package |baz.sty| by use of |\input baz.sty|

-
-Unfortunately, if you are upgrading the file |myclass.sty| to a class
-file then you have to make sure that any old files which contain
-|\input myclass.sty| still work.
-
-This was also true for the standard classes (|article|, |book| and
-|report|), since a lot of existing \LaTeX~2.09 document styles contain
-|\input article.sty|. The approach which we use to solve this is
-to provide minimal files |article.sty|, |book.sty| and |report.sty|,

\subsubsection{Make it robust}
We consider it good practice, when writing packages and classes, to use
\LaTeX{} commands as much as possible.
-Thus, instead of using |\def...| we recommend using one of
-|\newcommand|, |\renewcommand| or |\providecommand|; |\CheckCommand| is
-also useful. Doing this makes
-it less likely that you will inadvertently redefine a command, giving
-unexpected results.
+Thus, instead of using |\def...| we recommend using one of |\newcommand|,
+|\renewcommand| or |\providecommand| for programming and for defining document
+interfaces |\NewDocumentCommand|, etc. (see \texttt{usrguide} for details of
+these commands).
-When you define an environment, use |\newenvironment| or
-|\renewenvironment| instead |\def\foo{...}| and |\def\endfoo{...}|.
+When you define an environment, use |\NewDocumentEnvironment|, etc., (or
+|\newenvironment|, etc., for simple cases) instead of using |\def\foo{...}| and

-register, use |\setlength|.
+If you need to set or change the value of a \m{dimen} or \m{skip} register, use
+|\setlength|.

-|\mbox| and |\parbox| rather than |\setbox|, |\hbox| and |\vbox|.
+To manipulate boxes, use \LaTeX{} commands such as |\sbox|, |\mbox| and
+|\parbox| rather than |\setbox|, |\hbox| and |\vbox|.
-Use |\PackageError|, |\PackageWarning| or |\PackageInfo| (or the
-equivalent class commands) rather than |\@latexerr|, |\@warning| or
-|\wlog|.
-
-It is still possible to declare options by defining |\ds@<option>| and
-calling |\@options|; but we recommend the |\DeclareOption| and
-|\ProcessOptions| commands instead. These are more powerful and use
-less memory. So rather than using:
-\begin{verbatim}
- \def\ds@draft{\overfullrule 5pt}
- \@options
-\end{verbatim}
-you should use:
-\begin{verbatim}
- \DeclareOption{draft}{\setlength{\overfullrule}{5pt}}
- \ProcessOptions\relax
-\end{verbatim}
+Use |\PackageError|, |\PackageWarning| or |\PackageInfo| (or the equivalent
+class commands) rather than |\@latexerr|, |\@warning| or |\wlog|.
-The advantage of this kind of practice is that your code is more
-readable and, more important, that it is less likely to break when
-used with future versions of \LaTeX{}.
+The advantage of this kind of practice is that your code is more readable and
+accessible to other experienced \LaTeX{} programmers.
\subsubsection{Make it portable}
-It is also sensible to make your files are as portable as possible. To
-ensure this; they should contain only visible 7-bit text; and the
-filenames should contain at most eight characters (plus the three
-letter extension). Also, of course, it \textbf{must not} have the
-same name as a file in the standard \LaTeX{} distribution, however
-similar its contents may be to one of these files.
+It is also sensible to make your files are as portable as possible. To ensure
+this, files must not have the same name as a file in the standard \LaTeX{}
+distribution, however similar its contents may be to one of these files. It is
+also still lower risk to stick to file names which use only the ASCII range:
+whilst \LaTeX{} works natively with UTF-8, the same cannot be said with
+certainty for all tools. For the same reason, avoid spaces in file names.
-It is also useful if local classes or packages have a common prefix,
-for example the University of Nowhere classes might begin with |unw|.
-This helps to avoid every University having its own thesis class, all
-called |thesis.cls|.

please specify the release-date you need. For example, the package

+error commands were introduced in the June 2022 release so, if you use

- \NeedsTeXFormat{LaTeX2e}[1994/06/01]
+ \NeedsTeXFormat{LaTeX2e}[2022-06-01]
\end{verbatim}
\subsubsection{Useful hooks}
-Some packages and document styles had to redefine the command
-|\document| or |\enddocument| to achieve their goal. This is no
-longer necessary. You can now use the `hooks' |\AtBeginDocument| and
-|\AtEndDocument| (see Section~\ref{Sec:delays}). Again, using these
-hooks makes it less likely that your code breaks with future versions
-of \LaTeX{}. It also makes it more likely that your package can work
-together with someone else's.
-
-\NEWdescription{1996/12/01}
-However, note that code in the |\AtBeginDocument| hook is part of the
-preamble. Thus there are restrictions on what can be put there; in
-particular, no typesetting can be done.
+It is sometimes necessary for a package to arrange for code to be
+executed at the start or end of the preamble, at the end of the document
+or at the start of every use of an environment. This can be carried
+out by using hooks. As a document author, you will likely be familiar with
+|\AtBeginDocument|, a wrapper around the more powerful command |\AddToHook|.
+The \LaTeX{} kernel provides a large number of dedicated hooks (applying in
+a pre-defined location) and generic hooks (applying to arbitrary commands):
+the interface for using these is described in \texttt{lthooks} . There are
+also hooks to apply to files, described in \texttt{ltfilehooks}.

-The other major difference between \LaTeX~2.09 styles and \LaTeXe{}
-packages and classes is in option handling. Packages and classes can
-now declare options and these can be specified by authors; for

+\LaTeX{} supports two methods for creating options: a key--value system and a
+`simple text' approach. The key--value system is recommended for new classes
+and packages, and is more flexible in handling of option classes than the
+simple text approach. Both option methods use the same basic structure within
+the \LaTeX{} source: declaration of options first then processing options in a
+second step. Both also allow options to be passed on to other packages or an
+underlying class. As the `classical' simple text approach is conceptually more
+straight-forward to illustrate, it is used here to show the general structure:

-The following commands deal with the declaration and handling of
-options to document classes and packages. Every option name must be a
-`\LaTeX{} name'.
+As noted earlier, a sophisticated hook system is available and described in
+\texttt{lthooks}. Here, we document a small set of convenient short names for
+common hooks.
-There are some commands designed especially for use within the
-\m{code} argument of these commands (see below).
+These first two commands are also intended primarily for use within the
+\m{code} argument of |\DeclareOption| or |\DeclareOption*|.
\begin{decl}
- |\DeclareOption| \arg{option-name} \arg{code}
+ |\AtEndOfClass| \arg{code}\\
+ |\AtEndOfPackage| \arg{code}
\end{decl}
-This makes \m{option-name} a `declared option' of the class or package
-in which it is put.
-
-The \m{code} argument contains the code to be executed if that option
-is specified for the class or package; it can contain any valid
-\LaTeXe{} construct.
+These commands declare \m{code} that is saved away internally and then executed
+after processing the whole of the current class or package file.
-Example:
-\begin{verbatim}
- \DeclareOption{twoside}{\@twosidetrue}
-\end{verbatim}
+Repeated use of these commands is permitted: the code in the arguments is
+stored (and later executed) in the order of their declarations.
\begin{decl}
- |\DeclareOption*| \arg{code}
+ |\AtBeginDocument| \arg{code}\\
+ |\AtEndDocument| \arg{code}
\end{decl}
-This declares the \m{code} to be executed for every option which is
-specified for, but otherwise not explicitly declared by, the class or
-package; this code is called the `default option code' and it can
-contain any valid \LaTeXe{} construct.
+These commands declare \m{code} to be saved internally and executed while
+\LaTeX{} is executing |\begin{document}| or |\end{document}|.
-If a class file contains no |\DeclareOption*| then, by default, all
-specified but undeclared options for that class will be silently
-passed to all packages (as will the specified and declared options for
-that class).
+The \m{code} specified in the argument to |\AtBeginDocument| is executed near
+the end of the |\begin{document}| code, \emph{after} the font selection tables
+have been set up. It is therefore a useful place to put code which needs to be
+executed after everything has been prepared for typesetting and when the normal
+font for the document is the current font.
-If a package file contains no |\DeclareOption*| then, by default, each
-specified but undeclared option for that package will produce an error.
+The |\AtBeginDocument| hook should not be used for code that does any
+typesetting since the typeset result would be unpredictable.
+The \m{code} specified in the argument to |\AtEndDocument| is executed at the
+beginning of the |\end{document}| code, \emph{before} the final page is
+finished and before any leftover floating environments are processed. If some
+of the \m{code} is to be executed after these two processes, you should include
+a |\clearpage| at the appropriate point in \m{code}.

+Repeated use of these commands is permitted: the code in the arguments is

+\label{Sec:opt:keyval}
-These two commands can be used only within the \m{code} argument of
-either |\DeclareOption| or |\DeclareOption*|. Other commands commonly
-used within these arguments can be found in the next few subsections.
+As with any key--value input, using key--value pairs as package or class
+options has two parts: creating the key options and setting (using) them.
+Options created in this way \emph{may} be used after package loading as general
+key--value settings: this will depend on the nature of the underlying code.
\begin{decl}
- |\CurrentOption|
+ |\DeclareKeys| \oarg{family} \arg{declarations}
\end{decl}
-This expands to the name of the current option.
+This command creates a series of options from a comma-separated
+\m{declarations} list. Each entry in this list is a key--value pair, with the
+\m{key} having one or more \m{properties}. A small number of `basic'
+\m{properties} are described below. The full range of properties, provided by
+\texttt{l3keys}, can also be used for more powerful processing. See
+\texttt{interface3} for the full details.
+
+The basic properties provided here are
+\begin{itemize}
+ \item \texttt{.code} --- execute arbitrary code
+ \item \texttt{.if} --- sets a \TeX{} |\if...| switch
+ \item \texttt{.ifnot} --- sets an inverted \TeX{} |\if...| switch
+ \item \texttt{.store} --- stores a value in a macro
+ \item \texttt{.usage} -- defines whether the option can be given only
+ when loading (\texttt{load}), in the preamble (\texttt{preamble}) or
+ has no limitation on scope (\texttt{general})
+\end{itemize}
+The part of the \meta{key} before the \m{property} is the \m{name}, with the
+\m{value} working with the \m{property} to define the behaviour of the option.
+
+For example, with
+\begin{verbatim}
+\DeclareKeys[mypkg]
+ {
+ draft.if = @mypkg@draft ,
+ draft.usage = preamble ,
+ name.store = \@mypkg@name ,
+ name.usage = load ,
+ second-name.store = \@mypkg@other@name
+ }
+\end{verbatim}
+three options would be created. The option \texttt{draft} can be given anywhere
+in the preamble, and will set a switch called |\if@mypkg@draft|. The option
+\texttt{name} can only be given during package loading, and will save whatever
+value it is given in |\@mypkg@name|. Finally, the option \texttt{second-name}
+can be given anywhere, and will save its value in |\@mypkg@other@name|.
+
+Keys created \emph{before} the use of |\ProcessKeyOptions| act as package
+options.
\begin{decl}
- |\OptionNotUsed|
+ |\DeclareUnknownKeyHandler| \oarg{family} \arg{code}
\end{decl}
-This causes the current option to
-be added to the list of `unused options'.
+The command |\DeclareUnknownKeyHandler| may be used to define the behavior when
+an undefined key is encountered. The \m{code} will receive the unknown key name
+as |#1| and the value as |#2|. These can then be processed as appropriate,
+e.g.~by forwarding to another package.
-\NEWfeature{1995/06/01}
- You can now include hash marks (\texttt{\#}) within these \m{code}
- arguments without special treatment (formerly, it had been
- necessary to double them).
+\begin{decl}
+ |\ProcessKeyOptions| \oarg{family}
+\end{decl}
+The |\ProcessKeyOptions| function is used to check the current option list
+against the keys defined for \m{family}. Global (class) options and local
+(package) options are checked when this function is called in a package.

-\subsection{Option processing}
-\label{Sec:commands.options}
-
-\begin{decl}
- |\ProcessOptions|
-\end{decl}
-This command executes the \m{code} for each selected option.
-
-We shall first describe how |\ProcessOptions| works in a package file,
-and then how this differs in a class file.
-
-To understand in detail what |\ProcessOptions| does in a package file,
-you have to know the difference between \emph{local} and \emph{global}
-options.
-\begin{itemize}
-\item \textbf{Local options} are those which have been explicitly
- specified for this particular package in the \m{options} argument of
- any of these:
-\begin{quote}
- |\PassOptionsToPackage{<options>}| \ |\usepackage[<options>]|\\
- |\RequirePackage[<options>]|
-\end{quote}
-\item \textbf{Global options} are any other options that are specified
- by the author in the \m{options} argument of
- |\documentclass[<options>]|.
-\end{itemize}
-For example, suppose that a document begins:
-\begin{verbatim}
- \documentclass[german,twocolumn]{article}
- \usepackage{gerhardt}
-\end{verbatim}
-whilst package |gerhardt| calls package |fred| with:
-\begin{verbatim}
- \PassOptionsToPackage{german,dvips,a4paper}{fred}
- \RequirePackage[errorshow]{fred}
-\end{verbatim}
-then:
-\begin{itemize}
-\item |fred|'s local options are |german|, |dvips|, |a4paper|
- and |errorshow|;
-\item |fred|'s only global option is |twocolumn|.
-\end{itemize}
-
-When |\ProcessOptions| is called, the following happen.
-\begin{itemize}
-\item \emph{First}, for each option so far declared in |fred.sty|
- by |\DeclareOption|, it looks to see if that option is either a
- global or a local option for |fred|: if it is then the corresponding
- code is executed.
-
- This is done in the order in which these options
- were declared in |fred.sty|.
-\item \emph{Then}, for each remaining \emph{local} option, the command
- |\ds@<option>| is executed if it has been defined somewhere (other
- than by a |\DeclareOption|); otherwise, the `default option code' is
- executed. If no default option code has been declared then an error
- message is produced.
-
- This is done in the order in which these
- options were specified.
-\end{itemize}
-Throughout this process, the system ensures that the code declared for
-an option is executed at most once.
-
-Returning to the example, if |fred.sty| contains:
-\begin{verbatim}
- \DeclareOption{dvips}{\typeout{DVIPS}}
- \DeclareOption{german}{\typeout{GERMAN}}
- \DeclareOption{french}{\typeout{FRENCH}}
- \DeclareOption*{\PackageWarning{fred}{Unknown `\CurrentOption'}}
- \ProcessOptions\relax
-\end{verbatim}
-then the result of processing this document will be:
-\begin{verbatim}
- DVIPS
- GERMAN
- Package fred Warning: Unknown `a4paper'.
- Package fred Warning: Unknown `errorshow'.
-\end{verbatim}
-Note the following:
-
-\begin{itemize}
-\item the code for the |dvips| option is executed before that for the
- |german| option, because that is the order in which they are declared
- in |fred.sty|;
-\item the code for the |german| option is executed only once, when the
- declared options are being processed;
-\item the |a4paper| and |errorshow| options produce the warning from
- the code declared by |\DeclareOption*| (in the order in which they
- were specified), whilst the |twocolumn| option does not: this is
- because |twocolumn| is a global option.
-\end{itemize}
-
-In a class file, |\ProcessOptions| works in the same way, except
-that: \emph{all} options are local; and the default value for
-|\DeclareOption*| is |\OptionNotUsed| rather than an error.
-
-\NEWdescription{1995/12/01}
-Note that, because |\ProcessOptions| has a |*|-form, it is wise to
-follow the non-star form with |\relax|, as in the previous examples,
-since this prevents unnecessary look ahead and possibly misleading
-error messages being issued.
-
-\begin{decl}
- |\ProcessOptions*| \\
- |\@options|
-\end{decl}
-This is like |\ProcessOptions| but it executes the options in the
-order specified in the calling commands, rather than in the order of
-declaration in the class or package. For a package this means that the
-global options are processed first.
-
-The |\@options| command from \LaTeX~2.09 has been made equivalent to
-this in order to ease the task of updating old document styles to
-\LaTeXe{} class files.
-
-\begin{decl}
- |\ExecuteOptions| \arg{options-list}
-\end{decl}
-
-For each option in the \m{options-list}, in order,
-this command simply executes the command
-|\ds@<option>| (if this command is not defined, then that option is
-silently ignored).
-
-It can be used to provide a `default option list' just before
-|\ProcessOptions|. For example, suppose that in a class file you want
-to set up the default design to be: two-sided printing; 11pt fonts;
-in two columns. Then it could specify:
-\begin{verbatim}
- \ExecuteOptions{11pt,twoside,twocolumn}
-\end{verbatim}
-
+In the first example, the \textsf{article} class will be loaded with option
+|landscape| precisely when the current class is called with this option. By
+contrast, in the second example it will never be called with option |landscape|
+as in that case \textsf{article} is passed options only by the default option
+handler, but this handler is not used for |landscape| because that option is
+explicitly declared.

-\subsection{Defining commands}
-\label{Sec:commands.define}
-
-\LaTeXe{} provides some extra methods of (re)defining commands that are
-intended for use in class and package files.
-
-\NEWfeature{1994/12/01}
-The \texttt{*}-forms of these commands should be used to define
-commands that are not, in \TeX{} terms, long. This can be useful for
-error-trapping with commands whose arguments are not intended to
-contain whole paragraphs of text.
-
-\begin{decl}
- |\DeclareRobustCommand| \arg{cmd} \oarg{num} \oarg{default}
- \arg{definition}\\
- |\DeclareRobustCommand*| \arg{cmd} \oarg{num} \oarg{default}
- \arg{definition}
-\end{decl}
-This command takes the same arguments as |\newcommand| but it declares
-a robust command, even if some code within the \m{definition} is
-fragile. You can use this command to define new robust commands, or
-to redefine existing commands and make them robust. A log is put into
-the transcript file if a command is redefined.
-
-For example, if |\seq| is defined as follows:
-\begin{verbatim}
- \DeclareRobustCommand{\seq}[2][n]{%
- \ifmmode
- #1_{1}\ldots#1_{#2}%
- \else
- \PackageWarning{fred}{You can't use \protect\seq\space in text}%
- \fi
- }
-\end{verbatim}
-Then the command |\seq| can be used in moving arguments, even though
-|\ifmmode| cannot, for example:
-\begin{verbatim}
- \section{Stuff about sequences $\seq{x}$}
-\end{verbatim}
-
-Note also that there is no need to put a |\relax| before the
-|\ifmmode| at the beginning of the definition; this is because the
-protection given by this |\relax| against expansion at the wrong time
-will be provided internally.
-
-\begin{decl}
- |\CheckCommand| \arg{cmd} \oarg{num} \oarg{default}
- \arg{definition}\\
- |\CheckCommand*| \arg{cmd} \oarg{num} \oarg{default}
- \arg{definition}
-\end{decl}
-This takes the same arguments as |\newcommand| but, rather than define
-\m{cmd}, it just checks that the current definition of \m{cmd} is
-exactly as given by \m{definition}. An error is raised if these
-definitions differ.
-
-This command is useful for checking the state of the system before
-your package starts altering the definitions of commands. It allows
-you to check, in particular, that no other package has redefined the
-same command.
-

+ |\MakeTitlecase| \arg{text}
\end{decl}
-\NEWfeature{1995/06/01}
-\TeX{} provides two primitives |\uppercase| and |\lowercase| for
-changing the case of text. These are sometimes used in document
-classes, for example to set information in running heads in all
-capitals.
-
-Unfortunately, these \TeX{} primitives do not change the case of
-characters accessed by commands like |\ae| or |\aa|. To overcome this
-problem, \LaTeX{} provides two new commands |\MakeUppercase| and
-|\MakeLowercase| to do this.
-
-For example:
-\begin{quotation}
-\begin{tabular}{rl}
- |\uppercase{aBcD\ae\AA\ss\OE}| & \uppercase{aBcD\ae\AA\ss\OE}\\
- |\lowercase{aBcD\ae\AA\ss\OE}| & \lowercase{aBcD\ae\AA\ss\OE}\\
- |\MakeUppercase{aBcD\ae\AA\ss\OE}| &
- \MakeUppercase{aBcD\ae\AA\ss\OE}\\
- |\MakeLowercase{aBcD\ae\AA\ss\OE}| & \MakeLowercase{aBcD\ae\AA\ss\OE}
-\end{tabular}
-\end{quotation}
-
-The commands |\MakeUppercase| and |\MakeLowercase| themselves are
-robust, but they have moving arguments.
-
-The commands use the \TeX{} primitives |\uppercase| and |\lowercase|,
-and so have a number of unexpected `features'. In particular, they
-change the case of everything (except characters in the names of
-control-sequences) in their text argument: this includes mathematics,
-environment names, and label names.
-
-For example:
-\begin{verbatim}
- \MakeUppercase{$x+y$ in \ref{foo}}
-\end{verbatim}
-produces $X+Y$ and the warning:
-\begin{verbatim}
- LaTeX Warning: Reference `FOO' on page ... undefined on ...
-\end{verbatim}
-In the long run, we would like to use all-caps fonts rather than any
-command like |\MakeUppercase| but this is not possible at the moment
-because such fonts do not exist.
-
-\NEWdescription{1995/12/01}
-In order that upper/lower-casing will work reasonably well, and in
-order to provide any correct hyphenation, \LaTeXe{} \emph{must} use,
-throughout a document, the same fixed table for changing case.
-The table used is designed for the font encoding |T1|; this works well

-\label{Sec:upgrade}
-
-This section describes the changes you may need to make when you
-upgrade an existing \LaTeX{} style to a package or class but we shall
-start in optimistic mode.
-
-Many existing style files will run with \LaTeXe{} without any
-modification to the file itself. When everything is running OK,

-that it runs with the new standard \LaTeX{}; then distribute it to
-your users.
-
-\subsection{Try it first!}
-\label{Sec:try-it}
-
-The first thing you should do is to test your style in `compatibility
-mode'. The only change you need to make in order to do this is,
-possibly, to change the extension of the file to |.cls|: you should
-make this change only if your file was used as a main document style.
-Now, without any other modifications, run \LaTeXe{} on a document that
-uses your file. This assumes that you have a suitable collection of
-files that tests all the functionality provided by your style file.
-(If you haven't, now is the time to make one!)
-
-You now need to change the test document files so that they are
-\LaTeXe{} documents: see \emph{\usrguide} for details of how to do
-this and then try them again. You have now tried the test documents
-in both \LaTeXe{} native mode and \LaTeX~2.09 compatibility mode.

+\subsection{Querying localisation}
+
+Localisation information is needed to customise a range of outputs. The
+\LaTeX{} kernel does not itself manage localisation, which is well-served by
+the bundles \pkg{babel} and \pkg{polyglossia}. To allow the kernel and other
+packages to access the current localisation information provided by \pkg{babel}
+or \pkg{polyglossia}, the command \cs{BCPdata} is defined by the kernel. The
+initial kernel definition expands to tag parts for \texttt{en-US}, as the
+kernel does not track localisation but does start out with a broadly US~English
+setup. However, if \pkg{babel} or \pkg{polyglossia} are loaded, it is redefined
+expand to the BCP-47 information from the appropriate package. The supported
+arguments are the BCP-47 tag breakdowns:
\begin{itemize}
-\item \LaTeX{} now has a robust, well-defined designer's interface for
- selecting fonts, which is very different from the \LaTeX~2.09
- internals.
-\item Your style file may have used some \LaTeX~2.09 internal commands
- which have changed, or which have been removed.
+ \item \texttt{tag} The full BCP-47 tag (e.g.~\texttt{en-US})
+ \item \texttt{language} (e.g.,~\texttt{de})
+ \item \texttt{region} (e.g.,~\texttt{AT})
+ \item \texttt{script} (e.g.,~\texttt{Latn})
+ \item \texttt{variant} (e.g.,~\texttt{1901})
+ \item \texttt{extension.t} (transformation, e.g.,~\texttt{en-t-ja})
+ \item \texttt{extension.u} (additional locale
+ information, e.g.,~\texttt{ar-u-nu-latn})
+ \item \texttt{extension.x} (private use area, e.g.,~\texttt{la-x-classic})
\end{itemize}
+The information for the \emph{main} language for a document is be provided
+if these are prefixed by \texttt{main.}, e.g.~\texttt{main.language} will
+expand to the main language even if another language is currently active.
-When you are debugging your file, you will probably need more
-information than is normally displayed by \LaTeXe. This is achieved
-by resetting the counter |errorcontextlines| from its default value of
-$-1$ to a much higher value, e.g.~999.
-
-\subsection{Accommodating compatibility mode}
-
-Sometimes an existing collection of \LaTeX~2.09 documents makes it
-inconvenient or impossible to abandon the old commands entirely.
-If this is the case, then it is possible to accommodate both conventions
-by making special provision for documents processed in compatibility
-mode.
+In addition to the tag breakdown, the following semantic arguments are
+supported
+\begin{itemize}
+ \item \texttt{casing} The tag for case changing, e.g.~\texttt{el-x-iota}
+ could be selected rather than \texttt{el} to select a capital adscript
+ iota on uppercasing an \emph{ypogegrammeni}
+\end{itemize}
-\begin{decl}
-|\if@compatibility|
-\end{decl}
-This switch is set when a document begins with |\documentstyle| rather
-than |\documentclass|. Appropriate code can be supplied for either
-condition, as follows:
+For example, the case changing command \cs{MakeUppercase} is (conceptually)
+defined as
\begin{verbatim}
- \if@compatibility
- <code emulating LaTeX 2.09 behavior>
- \else
- <code suitable for LaTeX2e>
- \fi
+\ExpandArgs{e}\MakeUppercaseAux{\BCPdata{casing}}{#1}
\end{verbatim}
+where |#1| is the user input and the first argument to
+\cs{MakeUppercaseAux} takes two arguments, the locale and input text.
+
+\section{Commands superseded for new material}
+A small number of commands were introduced as part of \LaTeXe{} in the
+mid-1990s, are widely used but have been superseded by more modern methods.
+These are covered here as they are likely to be encountered routinely in
+existing classes and packages.
-\subsection{Font commands}
+\subsection{Defining commands}
-Some font and size commands are now defined by the document class
-rather than by the \LaTeX{} kernel. If you are upgrading a
-\LaTeX~2.09 document style to a class that does not load one of the
-standard classes, then you will probably need to add definitions for
-these commands.
+The \texttt{*}-forms of these commands should be used to define
+commands that are not, in \TeX{} terms, long. This can be useful for
+error-trapping with commands whose arguments are not intended to
+contain whole paragraphs of text.
\begin{decl}
- |\rm| |\sf| |\tt| |\bf| |\it| |\sl| |\sc|
+ |\DeclareRobustCommand| \arg{cmd} \oarg{num} \oarg{default}
+ \arg{definition}\\
+ |\DeclareRobustCommand*| \arg{cmd} \oarg{num} \oarg{default}
+ \arg{definition}
\end{decl}
-None of these short-form font selection commands are defined in the
-\LaTeXe{} kernel. They are defined by all the standard class files.
-
-If you want to define them in your class file, there are several
-reasonable ways to do this.
-
-One possible definition is:
-\begin{verbatim}
- \newcommand{\rm}{\rmfamily}
- ...
- \newcommand{\sc}{\scshape}
-\end{verbatim}
-This would make the font commands orthogonal; for example
-|{\bf\it text}| would produce bold italic, thus: \textbf{\textit{text}}.
-It will also make them produce an error if used in math mode.
+This command takes the same arguments as |\newcommand| but it declares a robust
+command, even if some code within the \m{definition} is fragile. You can use
+this command to define new robust commands, or to redefine existing commands
+and make them robust. A log is put into the transcript file if a command is
+redefined.
-Another possible definition is:
+For example, if |\seq| is defined as follows:
\begin{verbatim}
- \DeclareOldFontCommand{\rm}{\rmfamily}{\mathrm}
- ...
- \DeclareOldFontCommand{\sc}{\scshape}{\mathsc}
+ \DeclareRobustCommand{\seq}[2][n]{%
+ \ifmmode
+ #1_{1}\ldots#1_{#2}%
+ \else
+ \PackageWarning{fred}{You can't use \protect\seq\space in text}%
+ \fi
+ }
\end{verbatim}
-This will make |\rm| act like |\rmfamily| in text mode (see above) and
-it will make |\rm| select the |\mathrm| math alphabet in math mode.
-
-Thus |${\rm math} = X + 1$| will produce `${\rm math} = X + 1$'.
-
-If you do not want font selection to be orthogonal then you can
-follow the standard classes and define:
+Then the command |\seq| can be used in moving arguments, even though
+|\ifmmode| cannot, for example:
\begin{verbatim}
- \DeclareOldFontCommand{\rm}{\normalfont\rmfamily}{\mathrm}
- ...
- \DeclareOldFontCommand{\sc}{\normalfont\scshape}{\mathsc}
+ \section{Stuff about sequences $\seq{x}$}
\end{verbatim}
-This means, for example, that |{\bf\it text}| will produce medium
-weight (rather than bold) italic, thus: \textit{text}.
-\begin{decl}
- |\normalsize| \\
- |\@normalsize|
-\end{decl}
-The command |\@normalsize| is retained for compatibility with
-\LaTeX~2.09 packages which may have used its value; but redefining it
-in a class file will have no effect since it is always reset to have
-the same meaning as |\normalsize|.
-
-This means that classes \emph{must} now redefine |\normalsize| rather
-than redefining |\@normalsize|; for example (a rather incomplete one):
-\begin{verbatim}
- \renewcommand{\normalsize}{\fontsize{10}{12}\selectfont}
-\end{verbatim}
-Note that |\normalsize| is defined by the \LaTeX{} kernel to be an
-error message.
+Note also that there is no need to put a |\relax| before the |\ifmmode| at the
+beginning of the definition; this is because the protection given by this
+|\relax| against expansion at the wrong time will be provided internally.
\begin{decl}
- |\tiny| |\footnotesize| |\small| |\large|\\
- |\Large| |\LARGE| |\huge| |\Huge|
+ |\CheckCommand| \arg{cmd} \oarg{num} \oarg{default}
+ \arg{definition}\\
+ |\CheckCommand*| \arg{cmd} \oarg{num} \oarg{default}
+ \arg{definition}
\end{decl}
-None of these other `standard' size-changing commands are defined in
-the kernel: each needs to be defined in a class file if you need it.
-They are all defined by the standard classes.
-
-This means you should use |\renewcommand| for |\normalsize| and
-|\newcommand| for the other size-changing commands.
-
+This takes the same arguments as |\newcommand| but, rather than define \m{cmd},
+it just checks that the current definition of \m{cmd} is exactly as given by
+\m{definition}. An error is raised if these definitions differ.
-\subsection{Obsolete commands}
+This command is useful for checking the state of the system before your package
+starts altering the definitions of commands. It allows you to check, in
+particular, that no other package has redefined the same command.
-Some packages will not work with \LaTeXe{}, normally because they relied
-on an internal \LaTeX{} command which was never supported and has now
-changed, or been removed.
-
-In many cases there will now be a robust, high-level means of
-achieving what previously required low-level commands. Please consult
-Section~\ref{Sec:commands} to see if you can now use the \LaTeXe{}
-class and package writers commands.
-
-Also, of course, if your package or class redefined any of the kernel
-commands (i.e.~those defined in the files |latex.tex|, |slitex.tex|,
-|lfonts.tex|, |sfonts.tex|) then you will need to check it very
-carefully against the new kernel in case the implementation has
-changed or the command no longer exists in the \LaTeX2e{} kernel.
+\subsection{Option declaration}
+\label{Sec:commands.options.dec}
-Too many of the internal commands of \LaTeX~2.09 have been
-re-implemented or removed to be able to list them all here. You must
-check any that you have used or changed.
+The following commands deal with the declaration and handling of options to
+document classes and packages using a classical `simple text' approach. Every
+option name must be a `\LaTeX{} name'.
-We shall, however, list some of the more important commands which are
-no longer supported.
+There are some commands designed especially for use within the \m{code}
+argument of these commands (see below).
\begin{decl}
- |\tenrm| |\elvrm| |\twlrm| \dots\\
- |\tenbf| |\elvbf| |\twlbf| \dots\\
- |\tensf| |\elvsf| |\twlsf| \dots\\
- \qquad$\vdots$
+ |\DeclareOption| \arg{option-name} \arg{code}
\end{decl}
-The (approximately) seventy internal commands of this form are no longer
-defined. If your class or package uses them then \emph{please}
-replace them with new font commands described in \emph{\fntguide}.
+This makes \m{option-name} a `declared option' of the class or package in which
+it is put.
+
+The \m{code} argument contains the code to be executed if that option is
+specified for the class or package; it can contain any valid \LaTeXe{}
+construct.
-For example, the command |\twlsf| should be replaced by:
+Example:
\begin{verbatim}
- \fontsize{12}{14}\normalfont\sffamily\selectfont
+ \DeclareOption{twoside}{\@twosidetrue}
\end{verbatim}
-Another possibility is to use the |rawfonts| package, described in
-\emph{\usrguide}.
-
-Also, remember that many of the fonts preloaded by \LaTeX~2.09
-are no longer preloaded.
-
\begin{decl}
- |\vpt| |\vipt| |\viipt| \dots
+ |\DeclareOption*| \arg{code}
\end{decl}
-These were the internal size-selecting commands in \LaTeX~2.09.
-(They can still be used in \LaTeX~2.09 compatibility mode.)
-Please use the command |\fontsize| instead: see \emph{\fntguide} for
-details.
+This declares the \m{code} to be executed for every option which is specified
+for, but otherwise not explicitly declared by, the class or package; this code
+is called the `default option code' and it can contain any valid \LaTeXe{}
+construct.
-For example, |\vpt| should be replaced by:
-\begin{verbatim}
- \fontsize{5}{6}\normalfont\selectfont
-\end{verbatim}
+If a class file contains no |\DeclareOption*| then, by default, all specified
+but undeclared options for that class will be silently passed to all packages
+(as will the specified and declared options for that class).
+
+If a package file contains no |\DeclareOption*| then, by default, each
+specified but undeclared option for that package will produce an error.
+
+\subsection{Commands within option code}
+\label{Sec:within.code}
+
+These two commands can be used only within the \m{code} argument of either
+|\DeclareOption| or |\DeclareOption*|. Other commands commonly used within
+these arguments can be found in the next few subsections.
\begin{decl}
- |\prm|, |\pbf|, |\ppounds|, |\pLaTeX| \dots
+ |\CurrentOption|
\end{decl}
-\LaTeX~2.09 used several commands beginning with |\p| in order to
-provide `protected' commands. For example, |\LaTeX| was defined to be
-|\protect\pLaTeX|, and |\pLaTeX| was defined to produce the \LaTeX{}
-logo. This made |\LaTeX| robust, even though |\pLaTeX| was not.
-
-These commands have now been reimplemented using
-|\DeclareRobustCommand|
-(described in Section~\ref{Sec:commands.define}).
-If your package redefined one of the |\p|-commands then you must
-remove the redefinition and use |\DeclareRobustCommand| to redefine the
-non-|\p| command.
+This expands to the name of the current option.
\begin{decl}
-|\footheight|\\
-|\@maxsep|\\
-|\@dblmaxsep|
+ |\OptionNotUsed|
\end{decl}
-These parameters are not used by \LaTeXe{} so they have been removed,
-except in \LaTeX~2.09 compatibility mode. Classes should no longer
-set them.
-

+\begin{decl}
+ |\ProcessOptions|
+\end{decl}
+This command executes the \m{code} for each selected option.
-\end{thebibliography}
+We shall first describe how |\ProcessOptions| works in a package file, and then
+how this differs in a class file.
-\newpage
-\thispagestyle{empty}
+To understand in detail what |\ProcessOptions| does in a package file, you have
+to know the difference between \emph{local} and \emph{global} options.
+\begin{itemize}
+\item \textbf{Local options} are those which have been explicitly
+ specified for this particular package in the \m{options} argument of
+ any of these:
+\begin{quote}
+ |\PassOptionsToPackage{<options>}| \ |\usepackage[<options>]|\\
+ |\RequirePackage[<options>]|
+\end{quote}
+\item \textbf{Global options} are any other options that are specified
+ by the author in the \m{options} argument of
+ |\documentclass[<options>]|.
+\end{itemize}
+For example, suppose that a document begins:
+\begin{verbatim}
+ \documentclass[german,twocolumn]{article}
+ \usepackage{gerhardt}
+\end{verbatim}
+whilst package |gerhardt| calls package |fred| with:
+\begin{verbatim}
+ \PassOptionsToPackage{german,dvips,a4paper}{fred}
+ \RequirePackage[errorshow]{fred}
+\end{verbatim}
+then:
+\begin{itemize}
+\item |fred|'s local options are |german|, |dvips|, |a4paper|
+ and |errorshow|;
+\item |fred|'s only global option is |twocolumn|.
+\end{itemize}
-\section*{\LaTeXe{} Summary sheet: updating old styles}
+When |\ProcessOptions| is called, the following happen.
+\begin{itemize}
+\item \emph{First}, for each option so far declared in |fred.sty|
+ by |\DeclareOption|, it looks to see if that option is either a
+ global or a local option for |fred|: if it is then the corresponding
+ code is executed.
-Section references below are to \emph{\clsguide}.
+ This is done in the order in which these options
+ were declared in |fred.sty|.
+\item \emph{Then}, for each remaining \emph{local} option, the command
+ |\ds@<option>| is executed if it has been defined somewhere (other
+ than by a |\DeclareOption|); otherwise, the `default option code' is
+ executed. If no default option code has been declared then an error
+ message is produced.
-\begin{enumerate}
+ This is done in the order in which these
+ options were specified.
+\end{itemize}
+Throughout this process, the system ensures that the code declared for
+an option is executed at most once.
-\item Should it become a class or a package?
- See Section~\ref{Sec:classorpkg} for how to answer this question.
+Returning to the example, if |fred.sty| contains:
+\begin{verbatim}
+ \DeclareOption{dvips}{\typeout{DVIPS}}
+ \DeclareOption{german}{\typeout{GERMAN}}
+ \DeclareOption{french}{\typeout{FRENCH}}
+ \DeclareOption*{\PackageWarning{fred}{Unknown `\CurrentOption'}}
+ \ProcessOptions\relax
+\end{verbatim}
+then the result of processing this document will be:
+\begin{verbatim}
+ DVIPS
+ GERMAN
+ Package fred Warning: Unknown `a4paper'.
+ Package fred Warning: Unknown `errorshow'.
+\end{verbatim}
+Note the following:
-\item If it uses another style file, then you will need to obtain an
- updated version of this other file. Look at Section~\ref{Sec:loading}
- for information on how to load other class and package files.
+\begin{itemize}
+\item the code for the |dvips| option is executed before that for the
+ |german| option, because that is the order in which they are declared
+ in |fred.sty|;
+\item the code for the |german| option is executed only once, when the
+ declared options are being processed;
+\item the |a4paper| and |errorshow| options produce the warning from
+ the code declared by |\DeclareOption*| (in the order in which they
+ were specified), whilst the |twocolumn| option does not: this is
+ because |twocolumn| is a global option.
+\end{itemize}
-\item Try it: see Section~\ref{Sec:try-it}.
+In a class file, |\ProcessOptions| works in the same way, except that:
+\emph{all} options are local; and the default value for |\DeclareOption*| is
+|\OptionNotUsed| rather than an error.
-\item It worked? Excellent, but there are probably still some things
- you should change in order to make your file into a well-structured
- \LaTeXe{} file that is both robust and portable. So you should now
- read Section~\ref{Sec:writing}, especially~\ref{Sec:general}. You
- will also find some useful examples in Section~\ref{Sec:structure}.
+Note that, because |\ProcessOptions| has a |*|-form, it is wise to follow the
+non-star form with |\relax|, as in the previous examples, since this prevents
+unnecessary look ahead and possibly misleading error messages being issued.
- If your file sets up new fonts, font-changing commands or symbols,
- you should also read \emph{\fntguide}.
+\begin{decl}
+ |\ProcessOptions*|
+\end{decl}
+This is like |\ProcessOptions| but it executes the options in the order
+specified in the calling commands, rather than in the order of declaration in
+the class or package. For a package this means that the global options are
+processed first.
-\item It did not work? There are three possibilities here:
- \begin{itemize}
- \item error messages are produced whilst reading your file;
- \item error messages are produced whilst processing test documents;
- \item there are no errors but the output is not as it should be.
- \end{itemize}
- Don't forget to check carefully for this last possibility.
+\begin{decl}
+ |\ExecuteOptions| \arg{options-list}
+\end{decl}
- If you have got to this stage then you will need to read
- Section~\ref{Sec:upgrade} to find the solutions that will make your
- file work.
-\end{enumerate}
+It can be used to provide a `default option list' just before
+|\ProcessOptions|. For example, suppose that in a class file you want to set up
+the default design to be: two-sided printing; 11pt fonts; in two columns. Then
+it could specify:
+\begin{verbatim}
+ \ExecuteOptions{11pt,twoside,twocolumn}
+\end{verbatim}

-Or you know that your package is definitely not going to work with a

-\verb*/texdoc -l changes.txt/ you get more than thirty results and the

\section{New or improved commands}
+\subsection{Extending hooks to take arguments}
+
+Hooks have always been containers for code whose outcome was entirely
+dependent on the contents of the hook alone. If any type of contextual
+information had to be passed to the hook, it had to be done by setting
+some variable before the hook so that the code in the hook could use
+that. But this is somewhat hard to keep track of, clumsy to implement,
+and it required the programmer to have some kind of \enquote{hook before
+the hook} to do that setup.
+
+To make things a bit easier, \pkg{lthooks} was enhanced to support hooks
+with arguments. Hooks can now be declared and used with arguments, then
+the code added to these hooks can reference the hook's arguments using
+\verb|#1|, \verb|#2|, etc., so now hooks can behave more like macros
+than like \emph{token lists} (using \pkg{expl3} terminology). Regular
+argument-less hooks continue to work exactly like they did before: this
+extension is completely compatible with older documents and packages.
+
+\AddToHook{cmd/verbatim@font/after}[hack]{\small}
+To declare a hook with arguments, use
+\begin{verbatim}
+\NewHookWithArguments {<hook>} {<num args>}
+\end{verbatim}
+then, similarly, to use the code in the hook (supposing a hook declared
+with 2 arguments), write
+\begin{verbatim}
+\UseHookWithArguments {<hook>} {2} {<arg 1>} {<arg 2>}
+\end{verbatim}
+
+Or, if you want to add some code to a hook that takes arguments, write
+\begin{verbatim}
+\AddToHookWithArguments {<hook>} [<label>] {<code>}
+\end{verbatim}
+exactly like you would for regular hooks, except that the \meta{code}
+can use the arguments by referencing \verb|#1|, \verb|#2|, etc. In this
+case, if you want to add an actual parameter token (\verb|#|) to the
+\meta{code}, you have to double it, as usual.
+\RemoveFromHook{cmd/verbatim@font/after}[hack]
+
+Additionally, if you want to add \enquote{regular} code to a hook with
+arguments, you can still use \cs{AddToHook} --- in that case \verb|#|
+tokens are \emph{not} doubled. This means that a package author can
+decide to add arguments to an existing hook without worrying about
+compatibility: \cs{AddToHook} will do the right thing and will not
+mistakenly reference the newly added arguments.
+
+The commands \cs{NewReversedHookWithArguments}, \cs
+{NewMirroredHookPairWithArguments}, \cs
+{AddToHookNextWithArguments}, \cs{UseOneTimeHookWithArguments}, and
+the \pkg{expl3} conterparts of the commands discussed in this section
+were also added. The complete documentation can be found in the
+\pkg{lthooks} documentation \cite{37:lthooks-doc}.
+
+\subsubsection{Generic \texttt{cmd} hooks with arguments}
+
+Along with the possibility to pass arguments to a regular hook as
+discussed above, generic \hook{cmd} hooks now can access the arguments
+of the command they are patched into using the interface described in
+the previous section.
+
+For example, if you were to add some code to the \cs{title} command
+using hooks, you could access the actual title given in the argument.
+For example, to write the title of the document in the terminal you
+could use:
+\begin{verbatim}
+ \AddToHookWithArguments{cmd/title/before}
+ {\typeout{Document title: #1}}
+\end{verbatim}
+As with regular hooks, code added to a \hook{cmd} hook using
+\cs{AddToHook} will not be able to access the command's arguments. This
+means that, as with regular hooks, this change is completely backwards
+compatible, so previous usages of \hook{cmd} hooks will work exactly as
+they did before.

+\subsection{\cs{DeclareLowercaseMapping}, \cs{DeclareTitlecaseMapping}
+ and \cs{DeclareUppercaseMapping}}
+
+The move from a case-changing approach using \cs{lccode} and \cs{uccode} data
+to one where information is stored by a kernel-managed structure left a gap in
+the ability of the user to \emph{tune} the case changing outcomes. This has now
+been addressed by the addition of three commands
+\begin{itemize}
+ \item \cs{DeclareLowercaseMapping}
+ \item \cs{DeclareTitlecaseMapping}
+ \item \cs{DeclareUppercaseMapping}
+\end{itemize}
+which can be used to customise the outcome for codepoints. This can be applied
+generally or to a specific locale (see also the next section). A small number
+of pre-defined customisations have been set up in the kernel where the outcomes
+for \pdfTeX{} should be different for those from Unicode engines. For
+example
+\begin{verbatim}
+ \DeclareUppercaseMapping{"01F0}{\v{J}}
+\end{verbatim}
+allows \v{J} to be produced in 8-bit engines: without this customisation,
+an error would occur as there is no pre-composed \v{J} in Unicode. More detail
+is given in \texttt{usrguide}.
+%
+\githubissue{1033}
+
+\subsection{\cs{BCPdata}}
+
+Improvements in the Unicode handling for case changing have highlighted that
+the kernel has not to-date been locale-aware. The packages \pkg{babel} and
+\pkg{polyglossia} provide comprehensive locale support, but did not have
+an agreed unified interface to pass that information back to other code.
+Following discussion with the maintainers of those two bundles, the kernel
+now defines \cs{BCPdata} as a stub (so it is always defined), and \pkg{babel}
+and \pkg{polyglossia} will redefine it to provide the locale data. An agreed
+set of keywords mean that \cs{BCPdata} can be queried in a structured way
+by both the kernel and any other \enquote{consumer} packages.
+%
+\githubissue{1035}
+
+\subsection{Improve \cs{samepage}}
+
+The \cs{samepage} declaration sets various parameters to
+\texttt{10000} to prevent undesired page breaks. The
+\cs{predisplaypenalty} parameter has already by default a value of
+\texttt{10000} and to save space back in the days it was therefore not
+explicitly set. However, there are a few classes that change the
+parameter and as result the user might experience a page break in
+front of a display formula within the scope of \cs{samepage} when
+using such classes. This has now been corrected and
+\cs{predisplaypenalty} is also explicitly set to \texttt{10000}.
+%
+\githubissue{1022}
+\subsection{Groups in \cs{MakeUppercase}}
+%
+Prior to 2022, \cs{MakeUppercase} and \cs{MakeLowercase} used a brace
+group around their argument so providing a scope for any declarations
+within the argument. This grouping has been restored (also
+for \cs{MakeTitlecase}), although the underlying L3 text case commands do
+not use grouping.
+%
+\githubissue{1021}
+
+\subsection{Extension of the \cs{label} command}
+
+Previously, in standard \LaTeX{}, the \cs{label} command wrote a \cs{newlabel} declaration into
+the \texttt{.aux} file and stored two values in
+second argument of this \cs{newlabel} command:
+\cs{@currentlabel}, which normally contains the state of the current
+counter and \cs{thepage} for the current page number.
+
+The packages \pkg{hyperref} and
+\pkg{nameref} then patched the \cs{label} command to store five values instead.
+In addition to the above they saved \cs{@currentlabelname}, which normally contains the
+current title text and can be retrieved with \cs{nameref}, and
+\cs{@currentHref}, which is the name of the destination needed to create an
+active link. The fifth argument was only used if external
+references were loaded with the \pkg{xr-hyper} package.
+
+Starting with this release, the number of values stored in \cs{newlabel} have been unified.
+\cs{label} now writes a
+\cs{newlabel} command that always contains five values in the second argument (each in a brace group):
+\cs{@currentlabel}, \cs{thepage}, \cs{@currentlabelname},
+\cs{@currentHref}, and \cs{@kernel@reserved@label@data} (which is reserved for the kernel).
+
+Additionally, a hook with the name \texttt{label} has been
+added. It takes one argument: the label string.
+Code added to the hook can refer to this argument with \verb+#1+.
+The hook is executed directly before the \cs{label} command writes to the \texttt{.aux} file
+but \emph{after} the \cs{@bsphack} command has done its spacing magic and it is located \emph{inside} a group, thus its code only affects the write operation.

+authors and package/class developers in the two files \texttt{usrguide} and
+\texttt{clsguide}. Over time, the team have augmented these documents as new
+methods have been added to the kernel. However, they retained there structure
+as starting from familiarity with \LaTeX{}~2.09. This meant that for new users,
+there was material which is no longer relevant, and less clarity than desirable
+in what approaches are recommended today.
+
+The two files have now been (partially) re-written, with the versions available
+previously now frozen as \texttt{usrguide-historic} and \texttt{clsguide-historic}.
+More material has been carried forward in the class/package guide than in the
+user guide, but both are worth a re-read by experienced \LaTeX{} users.
+
+
+
+\subsection{Displaying the exact release dates for \LaTeX{}}
-\section{Changes to packages in the \pkg{amsmath} category}
+In some situations it is necessary to find out the exact release dates
+for older version of the \LaTeX{} format, for example, when you need
+to use different code in a package depending on the availability of a
+certain feature and you therefore want to use
+\cs{IfFormatAtLeastTF}\texttt\{\meta{date}\texttt\} or the
+rather horrible construction \verb/\@ifl@t@r\fmtversion{/\meta{date}\texttt\},
+if you
+want to cater for formats that are older than 2020.
-\section{Changes to packages in the \pkg{graphics} category}
+Or you know that your package is definitely not going to work with a
+format before a certain \meta{date}, in which case you could use
+\verb/\NeedsTeXFormat{LaTeX2e}[/\meta{date}\texttt] to ensure that any
+ user is alerted if their format is too old.
+
+The big problem is to know the exact \meta{date} to put into such
+commands and in the past that was not that easy to find. You could have
+looked in the the file \file{changes.txt}, but that is hidden somewhere
+in your installation and if you try
+\verb*/texdoc -l changes.txt/ you get more than thirty results and the %*
+right file is by no means the first.
+
+Yukai Chou (\textsf{@muzimuzhi}) kindly provided a patch for this, so that we now have
+the exact dates for each \LaTeX{} format listed in an easy to remember
+place: in \file{ltnews.pdf} and that file conveniently also contains all major
+features and changes to \LaTeX{} over the years\Dash one of which is
+most likely the reason you need the \meta{date} date in the first
+place.
+
+It is given in parentheses in the newsletter title, thus this
+newsletter tells you that on
+%
+\makeatletter
+\mbox{\expandafter\@gobblenonyear\@year\@nil
+ -\@julianmonthtonum\@month-\two@digits\@day}
+\makeatother
+%
+the command
+\cs{NewEnvironmentCopy}, a new \texttt{shipout} hook, etc.\ was made
+available. And looking into \file{ltnews.pdf} you can now easily find
+out that the \LaTeX3 programming layer was added on 2020-02-02
+(because the date was so nice) and not on the first of the month.

+\subsection{Fresh from the press: \enquote{The \LaTeX{} Companion, third edition} is now in print}
+
+The third edition of \emph{The \LaTeX{} Companion} is now
+available. This is the end of five years of careful work and we hope
+that it will provide our readers with all the information they need to
+successfully navigate the \LaTeX{} ecosystem and efficiently produce
+beautiful documents.
+
+Since the publication of the last edition (2004) a lot has happened in
+the \LaTeX{} world and thus a complete rewrite was necessary. All
+chapters have been thoroughly revised and in many cases largely
+extended to describe new important functionality and features. More
+than 5,000 add-on packages have been analyzed in detail, out of which
+roughly 10\% have been chosen for inclusion in \emph{The \LaTeX{}
+Companion}. All important aspects of these packages are described to
+provide the user once again with a satisfying one-stop–shop experience
+for the decade to come.
+
+To cover what we thought worth describing today, the book nearly
+doubled in size. The print edition is therefore produced as a
+two-volume set and sold as a bundle. Both volumes come as hard-cover
+with ribbons to easily mark pages in the book.
+
+To give you an idea of what is covered in the third edition you can
+find some excerpts at
+\begin{quote}
+\url{https://www.latex-project.org/news/2023/03/17/TLC3}
+\end{quote}
+
+The edition is also available as an eBook (Parts I and II combined)
+consisting of PDF and ePub format without DRM. Finally, the publisher
+offers the combination of the printed books and the digital versions at
+a very attractive price not available anywhere else.

-\subsection{Fix handling of nested \env{multicols}}
+\subsection{\pkg{multicol}: Better support for CJK languages}
+
+The default minimum depth of each column in a \env{multicols}
+corresponds to the depth of a \enquote{p} in the current font. This
+helps to get some uniformity if rules are used between the columns and
+makes sense for Latin-based languages. Until now it was hard-wired,
+but for CJK (Chinese/Japanese/Korean) languages it is better to use a zero depth, because there
+all characters have the same height and depth. And even with
+Latin-based languages one might want to use the depth of a \cs{strut}
+or that of a parenthesis. So we now offer a way to adjust this while
+maintaining backward compatibility. Just redefine
+\cs{multicolmindepthstring} to hold whatever you want to get measured
+for its depth (the width is not relevant).

+ \Large \bfseries To Err is Human --- Bug Contest
+\end{center}
+
+Any mistake found and reported is a gain for all readers of our book.
+For this reason Addison-Wesley and the authors offer a prize (for 5
+periods) to the eligible person who finds the largest
+number of bugs during that period (in case of a draw a random choice
+will be made between all those with the largest number of findings).
+A person can receive at most one prize, ever; errors found by any of
+the authors do not count.
+
+Each prize is a free choice of any single computing book found on the
+Addison-Wesley/Pearson web site:
+\texttt{https://www.informit.com} (that
+is, no boxed sets or multiple volume offers).
+
+
+As usual, the authors and publisher reserve the right to make various
+decisions such as whether a reported feature is an error for
+competitive purposes or whether similar features count as a single or
+multiple errors. ---
+Good luck!

+Due to its size the third edition of \textit{The \LaTeX{} Companion} is printed
+as a two-volume set. The digital version, however, is provided as a
+single PDF or ePub. This means that a small fraction of the digital
+content differs from that of the printed version: there is only a
+single font matter, a single bibliography, and a single index, whereas
+in the printed books these are separated out. However, all versions share the main
+matter (down to the page numbering) so most of the errata applies to
+all versions, but to a few only to the digital and others only to the
+printed version. Thus, we end up with three separate lists.

+\section*{Errata for the print version (not applicable to the digital version)}
+
+The printed books differ from the digital version in that the
+biligraphy is split across both volumes (with a few repeats) and that
+the font matter of each volume has its own table of contents and list
+of figures and tables. Therefore these parts have different page
+numbers and you will see similar errata entries for both print and
+digital differing only in that respect.

+% \subsection{Arguments and redefining commands}
+% \label{sec:redef-warn}
+%
+% The code in \pkg{ltcmdhooks} does its best to find out how many
+% arguments a given command has, and to insert the appropriate call to
+% \cs{UseHookWithArguments}, so that the arguments seen by the hook are
+% exactly those grabbed by the command (the hook, after all, is a macro
+% call, so the arguments have to be placed in the right order, or they
+% won't match).
+%
+% When using the package writer interface, as discussed in
+% section~\ref{sec:pkg-author}, to change the position of the hooks in
+% your commands, you are also free to change how the hook code in your
+% command sees its arguments. When a \hook{cmd} hook is declared with
+% \cs{NewHook} (or \cs{NewHookWithArguments} or other variations of
+% that), it loses its \enquote{generic} nature and works as a regular
+% hook. This means that you may choose to declare it without
+% arguments regardless if the command takes arguments or not, or
+% declare it with arguments, even if the command takes none.
+%
+% However, this flexibility should not be abused. When using a
+% nonstandard configuration for the hook arguments, think reasonably:
+% a user will expect that the argument \verb|#1| in the hook corresponds
+% to the argument's first argument, and so on. Any other configuration
+% is likely to cause confusion and, if used, will have to be well
+% documented.
+%
+% This flexibility, however, allows you to \enquote{correct} the
+% arguments for the hooks. For example, \LaTeX's \cs{refstepcounter}
+% has a single argument, the name of the counter. The \pkg{cleveref}
+% package adds an optional argument to \cs{refstepcounter}, making the
+% name of the counter argument \verb|#2|. If the author of
+% \pkg{cleveref} wanted, for whatever reason, to add hooks to
+% \cs{refstepcounter}, to preserve compatibility he could write
+% something along the lines of:
+% \begin{verbatim}
+% \NewHookWithArguments{cmd/refstepcounter/before}{1}
+% \renewcommand\refstepcounter[2][<default>]{%
+% \UseHookWithArguments{cmd/refstepcounter/before}{1}{#2}%
+% <code for \refstepcounter>}
+% \end{verbatim}
+% so that the mandatory argument, which is arg \verb|#2| in the
+% definition, would still be seen as \verb|#1| in the hook code.
+%
+% Another possibility would be to place the optional argument as the
+% second argument for the hook, so that people looking for it would be
+% able to use it. In either case, it would have to be well documented
+% to cause as little confusion as possible.

+% \subsection{Hooks with arguments}
+% \label{sec:hook-args}
+%
+% Sometimes it is necessary to pass contextual information to a hook,
+% and, for one reason or another, it is not feasible to store such
+% information in macros. To serve this purpose, hooks can be
+% declared with arguments, so that the programmer can pass along the
+% data necessary for the code in the hook to function properly.
+%
+% A hook with arguments works mostly like a regular hook, and most
+% commands that work for regular hooks, also work for hooks that take
+% arguments. The differences are when the hook is declared
+% (\cs{NewHookWithArguments} is used instead of \cs{NewHook}), then
+% code can be added with both \cs{AddToHook} and
+% \cs{AddToHookWithArguments}, and when the hook is used
+% (\cs{UseHookWithArguments} instead of \cs{UseHook}).
+%
+% \medskip
+%
+% A hook with arguments must be declared as such (before it is first
+% used, as all regular hooks) using
+% \cs{NewHookWithArguments}\Arg{hook}\Arg{number}. All code added to
+% that hook can then use \verb|#1| to access the first argument,
+% \verb|#2| to access the second, and so forth up to the number of
+% arguments declared. However, it is still possible to add code with
+% references to the arguments of a hook that was not yet declared
+% (we will discuss that later). At their core, hooks are macros, so
+% \TeX's limit of 9~arguments applies, and a low-level \TeX{} error
+% is raised if you try to reference an argument number that doesn't
+% exist.
+%
+% \medskip
+%
+% To use a hook with arguments, just write
+% \cs{UseHookWithArguments}\Arg{hook}\Arg{number} followed by a
+% braced list of the arguments. For example, if the hook \hook{test}
+% takes three arguments, write:
+%\begin{verbatim}
+% \UseHookWithArguments{test}{3}{arg-1}{arg-2}{arg-3}
+%\end{verbatim}
+% then, in the \meta{code} of the hook, all instances of \verb|#1|
+% will be replaced by \verb|arg-1|, \verb|#2| by \verb|arg-2| and so
+% on. If, at the point of usage, the programmer provides more
+% arguments than the hook is declared to take, the excess arguments
+% are simply ignored by the hook. Behaviour is
+% unpredictable\footnote
+% {The hook \emph{will} take the declared number of arguments, and
+% what will happen depends on what was grabbed, and what the hook
+% code does with its arguments.}
+% if too few arguments are provided. If the hook isn't declared,
+% \meta{number} arguments are removed from the input stream.
+%
+% \medskip
+%
+% Adding code to a hook with arguments can be done with
+% \cs{AddToHookWithArguments} as well as with the regular
+% \cs{AddToHook}, to achieve different outcomes. The main difference
+% when it comes to adding code to a hook, in this case, is firstly
+% the possibility of accessing a hook's arguments, of course, and
+% second, how parameter tokens (\verb|#|$_6$) are treated.
+%
+% Using \cs{AddToHook} in a hook that takes arguments will work as it
+% does for all other hooks. This allows a package developer to add
+% arguments to a hook that otherwise had none without having to worry
+% about compatibility. This means that, for example:
+%\begin{verbatim}
+% \AddToHook{test}{\def\foo#1{Hello, #1!}}
+%\end{verbatim}
+% will define the same macro \cs[no-index]{foo} regardless if the
+% hook \hook{test} takes arguments or not.
+%
+% Using \cs{AddToHookWithArguments} allows the \meta{code} added to
+% access the arguments of the hook with \verb|#1|, \verb|#2|, and so
+% forth, up to the number of the arguments declared in the hook.
+% This means that if one wants to add a \verb|#|$_6$ to the
+% \meta{code} that token must be doubled in the input. The same
+% definition from above, using \cs{AddToHookWithArguments}, needs to
+% be rewritten:
+%\begin{verbatim}
+% \AddToHookWithArguments{test}{\def\foo##1{Hello, ##1!}}
+%\end{verbatim}
+%
+% Extending the above example to use the hook arguments, we could
+% rewrite something like (now from declaration to usage, to get the
+% whole picture):
+%\begin{verbatim}
+% \NewHookWithArguments{test}{1}
+% \AddToHookWithArguments{test}{%
+% \typeout{Defining foo with "#1"}
+% \def\foo##1{Hello, ##1! Some text after: #1}%
+% }
+% \UseHook{test}{Howdy!}
+% \ShowCommand\foo
+%\end{verbatim}
+% Running the code above prints in the terminal:
+%\begin{verbatim}
+% Defining foo with "Howdy!"
+% > \foo=macro:
+% #1->Hello, #1! Some text after: Howdy!.
+%\end{verbatim}
+% Note how \verb|##1| in the call to \cs{AddToHookWithArguments}
+% became \verb|#1|, and the \verb|#1| was replaced by the argument
+% passed to the hook. Should the hook be used again, with a
+% different argument, the definition would naturally change.
+%
+% \bigskip
+%
+% It is possible to add code referencing a hook's arguments before
+% such hook is declared and the number of hooks is fixed. However,
+% if some code is added to the hook, that references more arguments
+% than will be declared for the hook, there will be a low-level
+% \TeX{} error about an \enquote{Illegal parameter number} at the
+% time the hook is declared, which will be hard to track down because
+% at that point \TeX{} can't know whence the offending code came
+% from. Thus it is important that package writers explicitly
+% document how many arguments (if any) each hook can take, so users
+% of those packages know how many arguments can be referenced, and
+% equally important, what each argument means.

+% because otherwise \TeX{} will throw a low-level error every time
+% some change happens to the hook (code is added, a rule is set, etc),

+% {\c__hook_hashes_tl 2}

+% {\c__hook_hash_tl 1}
+% {\c__hook_hash_tl 2}
+% ...
+% {\c__hook_hash_tl <n>}

+ \tl_set:Ne \l_@@_tmpa_tl { \@@_braced_cs_parameter:n { @@_tmp:w } }
+% \end{macrocode}
+% Now this function does the fun part. It is meant to be used with
+% \cs{prop_map_function:NN}, taking a label name in \verb|##1| and the
+% code stored in that label in \verb|##2|.
+% \begin{macrocode}
+ \cs_gset_protected:Npx \@@_normalise_fn:nn ##1 ##2
+ {
+% \end{macrocode}
+% Here we'll define two auxiliary macros: the first one throws an
+% error when it detects an invalid argument reference. It piggybacks
+% on \TeX's low-level \enquote{Illegal parameter number} error, but it
+% defines a weirdly-named control sequence so that the error comes out
+% nicely formatted. For example, if the label \enquote{badpkg} adds
+% some code that references argument \verb|#3| in the hook
+% \enquote{foo}, which takes only two arguments, the error will be:
+%\begin{verbatim}
+% ! Illegal parameter number in definition of hook 'foo'.
+% (hooks) Offending label: 'badpkg'.
+% <to be read again>
+% 3
+%\end{verbatim}
+% At the point of this definition, the error is raised if the code
+% happens to reference an invalid argument. If it was possible to
+% detect that this definition raised no error, the next step would be
+% unnecessary. We'll do all this in a group so this weird definition
+% doesn't leak out, and set \cs{tex_escapechar:D} to $-1$ so this hack
+% shows up extra nice in the case of an error.
+% \begin{macrocode}
+ \group_begin:
+ \int_set:Nn \tex_escapechar:D { -1 }
+ \cs_set:cpn
+ {
+ hook~'#1'. ^^J

+ \exp_not:v { c_@@_#1_parameter_tl }
+ {##2}
+ \group_end:
+% \end{macrocode}
+% This next macro, with a much less fabulous name, takes always nine
+% arguments, and it just transfers the code \verb|##2| under the label
+% \verb|##1| to the temporary property list. The first \meta{n}
+% arguments are taken from \cs[no-index]{l_@@_tmpa_tl}, and the other
+% $9-\meta{n}$ taken from \cs[no-index]{l_@@_tmpb_tl} (which contains

+% The default minimum depth of each column corresponds to the depth
+% of a `p' in the current font. This makes sense for Latin-based
+% languages and was hard-wired intitially, but for Asian languages
+% it is better to use a zero depth (and alternatively one might
