\changes{v0.0}{2018/09/05}{some user documentation} +% \section{The Purpose of this Package} +% This package has been made to give users a chance to combine the features of +% Piet van Oostrum's \Package{fancyhdr} \autocite{package:fancyhdr} with the +% features of \Package{scrlayer} \autocite{package:scrlayer}. In other words: +% It has been made to combine the page layers of \Package{scrlayer} with the +% page styles of \Package{fancyhdr}. +% +% In this combination compatibility with \Package{fancyhdr} is the first aim! +% Usability and the freedom provided by \Package{scrlayer} is only the second +% one. Compatibility with other packages or classes of \KOMAScript{} +% \cite{package:koma-script} is not a primary aim. Perhaps it will become an +% optional feature in future. Abolishing any real or virtual limitations of +% \Package{fancyhdr} other than make it possible to use layers is not an aim +% and will not be an aim in future. +% +% If you need a better combination of page styles and layers, you should +% either use the low level interface of \Package{scrlayer} to define your page +% styles or\,---\,and this is the recommendation of the author\,---\,use +% \Package{scrlayer-scrpage} instead of \Package{scrlayer-fancyhdr} or +% \Package{fancyhdr}. If you need more compatibility with other parts of +% \KOMAScript, i.\,e.\@ with the \KOMAScript{} classes, you should use +% \Package{scrlayer-scrpage} instead of \Package{scrlayer-fancyhdr} or +% \Package{fancyhdr}. +% +% +% \section{How it works} +% To combine \Package{fancyhdr} and \Package{scrlayer}, +% \Package{scrlayer-scrpage} loads both packages. After loading +% \Package{fancyhdr} it redefines page style \Pagestyle{@fancy} (up to +% \Package{fancyhdr} version 3.10) resp. \Pagestyle{f@nch@fancycore} (from +% \Package{fancyhdr} version 4) to make it a layer page style of +% \Package{scrlayer} using the newly defined layers \texttt{fancy.head.even}, +% \texttt{fancy.head.odd}, \texttt{fancy.foot.even} and +% \texttt{fancy.foot.odd}. The \texttt{\dots head\dots} layers are background +% layers like the page head of \Package{fancyhdr}'s page styles (or other +% usual page styles). The \texttt{\dots foot\dots} layers are foreground +% layers like the page footer of \Package{fancyhdr}'s page styles (or other +% usual page styles). The \texttt{\dots even} layers are restricted to even +% pages, that means left side pages in two-sided documents. The \texttt{\dots +% odd} layers are restricted to odd pages, that means right side pages in +% two-sided documents or all pages in single-sided documents. +% +% \DescribeMacro\ps@@fancy +% \DescribeMacro\ps@f@nch@fancycore +% \DescribeMacro\ps@fancyplain +% \DescribeMacro\ps@plain@fancy +% Note: Page style \Pagestyle{@fancy} (up to \Package{fancyhdr} version 3.10) +% resp. \Pagestyle{f@nch@fancycore} (from \Package{fancyhdr} version 4) is an +% internal basic page style of package \Package{fancyhdr}. It is used for the +% user page style \Pagestyle{fancy}. The user page style \Pagestyle{fancy} is +% also used for \Package{fancyhdr}'s deprecated page style +% \Pagestyle{fancyplain}, that also redefines page style \Pagestyle{plain} to +% be \Package{fancyhdr}'s internal page style \Pagestyle{plain@fancy}, that +% also uses \Pagestyle{fancy} but with \Macro{if@fancyplain} set to +% \Macro{iftrue}. There is also a deprecated command +% \Macro{fancyplain}\Parameter{plain code}\Parameter{fancy code}, that uses +% the \meta{plain code} if \Macro{if@fancyplain} is \Macro{iftrue} and +% \meta{fancy code} if \Macro{if@fancyplain} is \Macro{iffalse}. +% +% Note: Page styles defined using \Package{fancyhdr}'s command +% \Macro{fancypagestyle} also always use page style \Pagestyle{fancy} and so +% the internal basic page style \Pagestyle{@fancy} (up to \Package{fancyhdr} +% version 3.10) resp. \Pagestyle{f@nch@fancycore} (from \Package{fancyhdr} +% version 4). +% +% As a result of the two notes above, every page style of \Package{fancyhdr} +% always uses the same internal basic page style \Pagestyle{@fancy} (up to +% \Package{fancyhdr} version 3.10) resp. \Pagestyle{f@nch@fancycore} (from +% \Package{fancyhdr} version 4). As a result of redefining page style +% \Pagestyle{@fancy} (up to \Package{fancyhdr} version 3.10) +% resp. \Pagestyle{f@nch@fancycore} (from \Package{fancyhdr} version 4) to be +% a layer page style, users can add layers to or remove layers from all +% \Package{fancyhdr} page styles by adding layers to or remove layers from +% page style \Pagestyle{@fancy} (up to \Package{fancyhdr} version 3.10) +% resp. \Pagestyle{f@nch@fancycore} (from \Package{fancyhdr} version 4). You +% cannot add layers to or remove layers from \Package{fancyhdr}'s single page +% styles \Pagestyle{fancy}, \Pagestyle{fancyplain}, \Pagestyle{plain@fancy} or +% the page styles defined using \Macro{fancypagestyle} directly. So using +% layers is a all or nothing feature with \Package{scrlayer-scrpage}. However, +% you can use the second argument of \Macro{fancypagestyle} to add or remove +% layers whenever one of the \Package{fancyhdr} page styles is activated. So +% this is a move from the \Package{scrlayer} interface of adding or removing +% layers to single page styles to the \Package{fancyhdr} interface of defining +% modifications of page style \Pagestyle{fancy}. +% +% Another such movement from an \Package{scrlayer} user interface to a +% \Package{fancyhdr} user interface is the decision whether or not automatic +% running heads are used. \Package{scrlayer} provides the options +% \Option{automark} and \Option{manualmark} and commands \Macro{automark} and +% \Macro{manualmark} to do this decision and also to configure commands like +% \Macro{partmark}, \Macro{chaptermark}, \Macro{sectionmark} etc. With +% \Package{scrlayer-fancyhdr} also using page style \Pagestyle{@fancy} (up to +% \Package{fancyhdr} version 3.10) resp. \Pagestyle{f@nch@fancycore} (from +% \Package{fancyhdr} version 4) does switch to automatic running heads. The +% first activation of page style \Pagestyle{fancy} still redefines +% \Macro{chaptermark} and \Macro{sectionmark}, if a class with \Macro{chapter} +% is used, or \Macro{sectionmark} and \Macro{subsectionmark}, if a class +% without \Macro{chapter} is used. However, you still can use +% \Macro{manualmark} and \Macro{automark} after switching to a +% \Package{fancyhdr} page style to configure the running heads. So this +% movement is only partial. +% +% \DescribeMacro\ps@headings +% \DescribeMacro\ps@myheadings +% \DescribeMacro\ps@plain +% Note: Currently, neither \Package{scrlayer} nor \Package{fancyhdr} nor +% \Package{scrlayer-fancyhdr} do redefine page styles \Pagestyle{headings} or +% \Pagestyle{myheadings} by default. And neither \Package{scrlayer} nor +% \Package{fancyhdr} nor \Package{scrlayer-fancyhdr} do redefine page style +% \Pagestyle{plain} unless you are activating the deprecated +% \Package{fancyhdr} page style \Pagestyle{fancyplain}. So if you like to use +% layers on \Pagestyle{plain} pages, i.\,e. usually the first page of a +% chapter or part or the page with a title head, you have to either use +% \Package{fancyhdr}'s deprecated page style \Pagestyle{fancyplain} or +% redefine page style \Pagestyle{plain} either using \Macro{fancypagestyle} as +% documented in the \Package{fancyhdr} manual or using +% \Macro{DeclareNewPageStyleByLayers}, documented in the \KOMAScript{} manual. +% However from version 4.0 \Package{fancyhdr} provides options +% \Option{myheadings} and \Option{headings} to redefine the corresponding page +% style. \Package{scrlayer-fancyhdr} also provides these options and passes +% them to \Package{fancyhdr}. +% +% \DescribeMacro\ps@empty +% \DescribeMacro\ps@@empty +% Note: Pagestyle \Pagestyle{empty} is somehow special. \Package{scrlayer} +% redefines it to be a layer page style. And \Package{fancyhdr}'s internal +% page style \Pagestyle{@empty} is the same like \Pagestyle{empty}. So +% \Pagestyle{@empty} also uses the layers of \Pagestyle{empty} but you should +% not try to modify it directly using the interface of +% \Package{scrlayer}. Moreover, if \Package{fancyhdr} is loaded before +% \Package{scrlayer-scrpage}, \Package{fancyhdr}'s internal page style +% \Pagestyle{@empty} is not a copy of \Package{scrlayer}'s layer page style +% \Pagestyle{empty} but the original standard page style +% \Pagestyle{empty}. However, with \Package{scrlayer-fancyhdr} package +% \Package{fancyhdr} does not longer use the internal page style +% \Pagestyle{@empty}. So you would not need to know this. +% +% \section{How to use the Package} +% +% To use the package you have to load it, e.\,g., using: +%\begin{verbatim} +% \usepackage{scrlayer-fancyhdr} +%\end{verbatim} +% instead of loading \Package{scrlayer} and \Package{fancyhdr} or before or +% after loading one of these packages. However it is recommended to replace +% loading \Package{scrlayer} and \Package{fancyhdr} by loading +% \Package{scrlayer-fancyhdr} because this avoids option +% clashes. \Package{scrlayer-fancyhdr} provides all options of +% \Package{scrlayer} and \Package{fancyhdr} and passes them to +% \Package{scrlayer} resp. \Package{fancyhdr}. Nevertheless +% sometimes it may be useful to be able to additionally load +% \Package{scrlayer} or \Package{fancyhdr}. +% +% \DescribeMacro\ps@@fancy +% \DescribeMacro\ps@f@nch@fancycore +% \DescribeMacro\ps@fancy +% \DescribeMacro\ps@fancyplain +% \DescribeMacro\ps@plain@fancy +% \DescribeMacro\fancypagestyle +% After this you should be able to use the page styles and commands of +% \Package{fancyhdr} and to add layers to or remove layers from the +% \Package{fancyhdr}'s internal basic page style \Package{@fancy} (up to +% \Package{fancyhdr} version 3.10) resp. \Pagestyle{f@nch@fancycore} (from +% \Package{fancyhdr} version 4). Note, you are not able to add layers to or +% remove layers from \Package{fancyhdr}'s page styles \Pagestyle{fancy}, +% \Pagestyle{fancyplain}, \Pagestyle{plain@fancy} or page styles defined by +% \Macro{fancypagestyle}. However adding layers to or removing layers from +% \Pagestyle{@fancy} (up to \Package{fancyhdr} version 3.10) +% resp. \Pagestyle{f@nch@fancycore} (from \Package{fancyhdr} version 4) will +% always change all these page styles! +% +% \DescribeMacro\ps@plain +% \DescribeMacro\ps@headings +% \DescribeMacro\ps@myheadings +% \DescribeMacro\ps@empty +% Note: Loading \Package{scrlayer-fancyhdr} will not make page style +% \Pagestyle{plain} nor \Pagestyle{headings} nor \Pagestyle{myheadings} or any +% other page style but \Pagestyle{empty} to automatically be a layer page +% style! But if you are using option \Option{headings} or \Option{myheadings} +% package \Package{fancyhdr} redefines the corresponding page styles to be +% \Package{fancyhdr} page styles\,---\,and so become layer page styles. +% +% \section{Known Issues} +% +% Please note, the follow issues are either notes to the package author or +% notes to the user to avoid them reporting the same issues again and +% again. Listing these issues does not say they are bugs or features. +% +% \begin{itemize} +% \item +% \DescribeMacro\ps@fancy +% \DescribeMacro\ps@f@nch@fancycore +% \DescribeMacro\ps@fancyplain +% \DescribeMacro\fancypagestyle +% \DescribeMacro\ps@@fancy +% You are not able to add layers to the user level page style +% \Pagestyle{fancy} or \Pagestyle{fancyplain} or any page style defined by +% \Macro{fancypagestyle} but only to the internal page style +% \Pagestyle{@fancy} (if you are using \Package{fancyhdr} up to version +% 3.10) resp. \Pagestyle{f@nch@fancycore} (if you are using +% \Package{fancyhdr} from version 4). This is intended as explained in this +% manual. +% \item +% \DescribeMacro\ps@@empty +% Using \Package{fancyhdr}'s internal page style \Pagestyle{@empty} +% could have strange results. However, there is a simple solution for this: +% Don't use the internal \Pagestyle{@empty} but always the user level page +% style \Pagestyle{empty}! +% \item +% \DescribeMacro\ps@@fancy +% \DescribeMacro\ps@f@nch@fancycore +% The vertical position of the page header does differ a little bit, if +% \Package{scrlayer-fancyhdr} is used instead of \Package{fancyhdr}. This +% could be fixed by a modification of the layers \texttt{fancy.head.odd} and +% \texttt{fancy.head.even} using \Option{addvoffset}. More tests are needed. +% \end{itemize} +% +%\iffalse +% +%\fi +% +% \StopEventually{} +% +% \section{Implementation of \Package{scrlayer-fancyhdr}} +% \label{sec:scrlayer-fancyhdr} +% +% \iffalse +%<*package> +% \fi +% +% This section if for developers only. +% +% We need \Package{scrlayer} at least version 2021/02/15, +% \begin{macrocode} +%<*init> +\RequirePackage{scrlayer}[2021/02/15] +% +% \end{macrocode} +% Because before \cs{scrlayer@do@inherited@options} would not be defined. And +% we need it, to inherit all options of \Package{scrlayer}. +% \begin{macrocode} +%<*options> +\scrlayer@do@inherited@options{\scrlayer@inherit@option} +% +% \end{macrocode} +% +% And the very first thing at the body, after definition of the options is to +% process the options. +% \begin{macrocode} +%<*body> +\KOMAProcessOptions +% +% \end{macrocode} +% +% Note: The main problem of this interface is, that it tries to implement the +% user interface of package \Package{fancyhdr} by Piet van Oostrum, that is +% completely different from \Package{scrlayer} and not really compatible with +% \Package{scrlayer}, using \Package{scrlayer}. This means, that +% \Package{scrlayer-fancyhdr} never can be a drop-in replacement of +% \Package{fancyhdr}. Nevertheless it can help to let \Package{scrlayer} and +% \Package{fancyhdr} coexist. To do so +% \begin{itemize} +% \item the lowest level of \Package{fancyhdr} should not be the page style +% but a layer +% \item the page styles of \Package{fancyhdr} should be layer page styles +% \item init code of the page styles of \Package{fancyhdr} should use the +% layer page init code +% \end{itemize} +% Currently it is unsure whether it would be best to do a new implementation +% or to load original \Package{fancyhdr} and to only modify some things. First +% I'll try the second method. Currently we explicitly provide the options of +% \Package{fancyhdr}. +% \begin{macrocode} +%<*options> +\DeclareOption{nocheck}{\PassOptionsToPackage{nocheck}{fancyhdr}} +\DeclareOption{compatV3}{\PassOptionsToPackage{compatV3}{fancyhdr}} +\DeclareOption{myheadings}{\PassOptionsToPackage{myheadings}{fancyhdr}} +\DeclareOption{headings}{\PassOptionsToPackage{headings}{fancyhdr}} +% +% \end{macrocode} +% \begin{macrocode} +%<*body> +\RequirePackage{fancyhdr} +% +% \end{macrocode} +% +% We need at least one new layer for the new layer page style +% \Pagestyle{fancy}.

To do so \Package{fancyhdr} first uses a different +% page style definition, that does the initialization and redefines the page +% style afterwards. This is still active with \Package{scrlayer-fancyhdr}. +% Additionally, \Package{fancyhdr} redefines \cs{@mkboth} at every selection +% of the internal page style \Pagestyle{@fancy} +% resp. \Pagestyle{f@nch@fancycore}. This can be adapted using the +% \Option{onselect} feature of the new layer page style \Pagestyle{@fancy} +% resp. \Pagestyle{f@nch@fancycore}. In my opinion, the +% |\let\@mkboth\markboth| used by page style \Pagestyle{headings} of, e.\,g., +% the standard classes or the \KOMAScript{} classes would be best +% here. However, \Package{fancyhdr} uses the uncommon +% |\def\@mkboth{\protect\markboth}|, which would fail if a class or package +% tests \cs{@mkboth} using |\ifx\@mkboth\markboth|. However, \KOMAScript's +% \cs{IfActiveMkBoth} (see the \Package{scrbase} chapter in the \KOMAScript{} +% manual) does also recognize the \Package{fancyhdr} definition and copying +% this is more compatible with \Package{fancyhdr}. +% \begin{macrocode} +\@ifpackagelater{fancyhdr}{2019/03/21}{% + \DeclarePageStyleByLayers[ + onselect={\def\@mkboth{\protect\markboth}}, + ]{f@nch@fancycore}{% + fancy.head.odd,fancy.head.even,fancy.foot.odd,fancy.foot.even + }% +}{% + \DeclarePageStyleByLayers[ + onselect={\def\@mkboth{\protect\markboth}}, + ]{@fancy}{% + fancy.head.odd,fancy.head.even,fancy.foot.odd,fancy.foot.even + }% +} +% +% \end{macrocode} +% Note: Redefining page style \Pagestyle{@fancy} +% resp. \Pagestyle{f@nch@fancycore} instead of \Pagestyle{fancy} +% does also mean, that features like options \Option{automark} and +% \Option{manualmark} resp. \cs{automark} and \cs{manualmark} are not fully +% supported by \Package{scrlayer-fancyhdr}. Also currently the font features +% of the \KOMAScript{} classes are not supported by +% \Package{scrlayer-fancyhdr}. However you are now able to combine other +% features of \Package{scrlayer} with features of \Package{fancyhdr} and you +% can, e.g., use \Package{scrlayer-notecolumn} with +% \Package{scrlayer-fancyhdr}. +% \end{macro}%^^A \@mkboth +% \end{macro}%^^A \ps@@fancy +% \end{macro}%^^A \ps@f@nch@fancycore +% +% A future release of \Package{scrlayer-fancyhdr} may even provide the font +% features of the \KOMAScript{} classes and a working +% \Option{markcase}. However, in this case I would have to redefine the +% initial page style \Pagestyle{fancy} and the layers above. +% +% \iffalse +% +% \fi +% +% \Finale +% +\endinput +% +% End of file `scrlayer-fancyhdr.dtx'. +% + +%%% Local Variables: +%%% mode: doctex +%%% mode: flyspell +%%% ispell-local-dictionary: "en_GB" +%%% TeX-master: t +%%% End: -- cgit v1.2.3
