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. +% % \MaybeStop{\setlength\IndexMin{200pt} \PrintIndex } % % @@ -366,10 +438,13 @@ % \end{macro} % \end{macro} % -% \begin{macro}{\c_@@_hash_tl} -% A constant token list that contains two parameter tokens. +% \begin{macro}{\c_@@_hash_tl,\c_@@_hashes_tl} +% Two constant token lists that contain one and two parameter tokens. +% \changes{v1.0g}{2023/04/06} +% {Rename to \cs{c_@@_hashes_tl} and add \cs{c_@@_hash_tl} (hook-args).} % \begin{macrocode} -\tl_const:Nn \c_@@_hash_tl { # # } +\tl_const:Nn \c_@@_hash_tl { # } +\tl_const:Nn \c_@@_hashes_tl { # # } % \end{macrocode} % \end{macro} % @@ -702,7 +777,7 @@ % % \changes{v1.0f}{2021/10/20} % {Correct patching by expansion+redefinition when the macro -% contains a parameter tokens (gh/697).} +% contains a parameter token (gh/697).} % Patching with expansion+redefinition is trickier than it looks like % at first glance.

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. +% % \subsection{Private \LaTeX{} kernel hooks} % % There are a few places where it is absolutely essential for @@ -1461,7 +1745,7 @@ % package/class name if called inside such a file % (see section~\ref{sec:default-label}). % -% This way one can add further code to the hook using +% This way one can add code to the hook using % \cs{AddToHook} or \cs{AtBeginDocument} using a different label % and explicitly order the code chunks as necessary, e.g., run some % code before or after another package's code.
