This has +% been noted in the \LaTeX\ bugs database.^^A +% \footnote{See \url{http://www.Uni-Mainz.DE/cgi-bin/ltxbugs2html}: +% \href{http://www.latex-project.org/cgi-bin/ltxbugs2html?pr=latex/2361}{latex/2361}, +% \href{http://www.latex-project.org/cgi-bin/ltxbugs2html?pr=latex/2484}{latex/2484}, +% \href{http://www.latex-project.org/cgi-bin/ltxbugs2html?pr=latex/2617}{latex/2617}.} +% +% +% The problem occurs most likely when a marginpar appears near +% the top of a page. The problem is exacerbated when +% the page break penalties are adjusted so that the page look is +% quite ragged. In cases like this, if there is a deal of white +% space on a page, the marginpars on the next page will be on the +% wrong side for the same length of the page. +% The reason for this is that the \LaTeX\ output routine is not +% in complete synchronization with the \TeX\ page breaker, so that +% sometimes +% material might still move to a later page \emph{after} \LaTeX's +% marginpar algorithm has determined a page number for the marginpar. +% +% The fix suggested in the bugs database is to insert |\pagebreak| +% commands at the places where the page breaks naturally fall; +% then the marginpars will appear on the correct side. However, this is +% awkward and unpleasant work for a document that changes +% regularly, and seems to fly against the spirit of \LaTeX. +% +% A different approach was suggested by D. E. Knuth in his +% \emph{Macros for Jill}\footnote{Originally published in TUGboat +% \textbf{8}, pp.~309--314, reprinted in his \emph{Digital +% Typography} pp.~185--193.}: make two |.dvi| files, one with all +% notes in the left margin, the other one with all notes in the +% right margin. Then print the odd pages from one file, and the +% even pages from the other file; merge them by hand. +% +% However, Knuth also mentions the possibility to use an auxiliar +% file to save the page information for each marginpar and use this +% information to position it correctly in a second \TeX\ run; and +% this is the strategy adopted by \PackageName. +% Each marginpar is assigned a unique number; the output routine +% writes the number of the last marginpar of each page\slash column +% to the |.aux| file, and this information is used in +% |\@addmarginpar| to position the current marginpar on the correct +% margin. +% +% +% ^^A -------------------------------------------------- +% \section{Usage} +% ^^A -------------------------------------------------- +% Just insert |\usepackage{mparhack}| into your document preamble. +% After the first run, you'll probably get the warning message +% `\texttt{Marginpars may have changed. Rerun to get them right}'. +% This is similar to \LaTeX's warning `\texttt{Label(s) may have +% changed}'; it indicates that the |.aux| file doesn't contain the +% information needed to position the marginpars correctly, due to +% some changes in the document since the last run. The warning +% should go away after running \LaTeX\ again (eventually several +% times if there's also a table of contents etc.). +% +% \DescribeMacro{debug}^^A +% If you think something is going wrong, the package also has a +% \texttt{debug} option; this will output a lot of tracing +% information and will add numbers to the marginpars in the |.dvi| +% file for reference. +% +% +% ^^A -------------------------------------------------- +% \section{Bugs\slash Restrictions} +% ^^A -------------------------------------------------- +% \begin{itemize} +% \item +% The package works with the |twocolumn| document option, but not +% with the |multicol| package (you can't use marginpars inside +% the |multicols| environment). +% \item +% The package uses one command sequence per page, and the total number +% of command sequences available is limited on most \TeX\ systems. +% Note however that most current \TeX\ implementations +% can allocate more than several thousand command names, and some can +% be configured to allocate more than the default during run-time, +% so this shouldn't be a problem for moderately sized documents. +% \item +% The package has to hook into three commands of the \LaTeX2e\ output +% routine (by redefining some command), so it requires at least +% \LaTeX\ version 1997/04/14 and might break with future \LaTeX\ +% versions that change these commands. +% We try to detect this by requiring a version newer than 1997/04/14 +% and using some heuristics to check if the redefinitions have worked. +% You should watch out for this warning message:\par +% {\ttfamily\footnotesize\begin{tabular}{@{}l@{}l@{}} +%LaTeX Warning:&\ You have requested release `1997/04/14' of LaTeX,\\ +% &\ but only release `...' is available. +% \end{tabular}}\par\noindent +% It might be that the package also works with older versions of \LaTeX, +% but this hasn't been tested. If one of the heuristics detects an incompatible +% change, it will raise an error:\par +% {\ttfamily\footnotesize\begin{tabular}{@{}l@{}} +%Package mparhack Error: Couldn't hook into command `xyz'. +% \end{tabular}}\par\noindent +% \vskip-\lastskip\noindent +% It might also happen that the heuristics don't detect a change +% properly. If the package simply seems to fail, this could be a reason. +% In both cases, please send a bug report to +% \href{mailto:stefanulrich@users.sourceforge.net}{\texttt{stefanulrich@users.sourceforge.net}} +% (if neccessary including the +% |.log| file of your \LaTeX\ run with the \texttt{debug} +% package option enabled). Suggestions/improvements are also welcome, +% of course. +% \end{itemize} +% +% ^^A -------------------------------------------------- +% \section{Acknowledgements} +% ^^A -------------------------------------------------- +% Thanks to Donald Arseneau and Robin Fairbairns for providing +% detailed hints\footnote{in \texttt{<23AUG199920123097@erich.triumf.ca>} and +% \texttt{<7prb8s\$dpr\$1@pegasus.csx.cam.ac.uk>}, respectively.} +% on how to implement the page referencing mechanism using only one +% label per page (instead of one label each marginpar, as in a +% previous version). +% +% ^^A -------------------------------------------------- +% ^^A Place to stop if implementation shouldn't be printed +% ^^A -------------------------------------------------- +% +% \typein[\answer]% +% {^^JPrint an annotated listing of the macro definitions (y/n)?

Then when reading the |.aux| +% file at the begin of the \LaTeX\ run, |\mph@nr| will be substitued +% by the number of the last marginpar (the value of the |\mph@nr| command +% read before that), +% and |\mph@setcol| will assign that number to the command sequence |\csname| +% |mph@last@|$x{\texttt{:}}$|\thepage\endcsname|; so this will contain +% the number of the last marginpar on column\slash page $x{\texttt{:}}$|\thepage|. +% +% Later on, in the document itself, |\@addmarginpar| will be able to check the value of +% |\csname| |mph@last@|$x{\texttt{:}}$\Com{thepage}\Com{end\-csname}, +% using the current values for $x$ and |\thepage|. Then there are two +% cases: +% +% (a) |\csname| |mph@last@|$x{\texttt{:}}$|\thepage\endcsname| is +% undefined, which means that there has been no |.aux| file +% previously, or that there are more pages\slash marginpars than in +% the previous run; in this case, |\@addmarginpar| will fall back to using +% the value of |\c@page| to determine the current page number (yielding the +% same result as without this package), or +% +% (b) |\csname| |mph@last@|$x{\texttt{:}}$|\thepage\endcsname| is defined as +% an integer $z$, the number of the last marginpar on |\thepage|. +% Then $z \leq n$, the number of the current marginpar.^^A +% \footnote{$z$ cannot be greater than $n$: this would +% mean that \TeX\ had shifted some material (including a marginpar) +% from later pages to earlier pages, which AFAIK cannot happen.} +% While $z < n$, the page counter will be incremented (inside a group) +% until |\csname| |mph@last@|$x{\texttt{:}}$|\thepage\endcsname| for +% that new page is $\geq n$, or until +% we end up in case (a). The incremented value for the page counter +% now represents the actual page number of the current marginpar, +% and it will be used instead of the original page counter in the +% check for even-\slash oddness. +% +% ^^A -------------------------------------------------- +% \subsection{Code} +% ^^A -------------------------------------------------- +% +% We need at least \LaTeX\ version 1997/04/14 which introduced +% |\normalsfcodes| into |\@outputdblcol|. +% \begin{macrocode} +%<*sty> +\NeedsTeXFormat{LaTeX2e}[1997/04/14] +\ProvidesPackage{mparhack} + [2003/05/22 v1.3a (T.

As a heuristic of +% detecting whether we change the appropriate commands, we check +% the values of some special counters \Com{mph@chk@xyz} that get +% incremented by some of the `hooks'. +% +% \changes{v1.3a}{2003/05/22}{% +% Use \Com{g@addto@macro} for \Com{@outputpage} to +% improve compatibility with e.g. the memoir class +% }% +% \changes{v1.2}{2000/02/29}{% +% Added \Com{CheckCommand*} for \Com{@addmarginpar}, \Com{@outputpage} +% and \Com{@outputdblcol} +% }% +% \changes{v1.2b}{2000/09/01}{% +% Replaced \Com{CheckCommand*} and the full redefinitions of +% \Com{@addmarginpar}, \Com{@outputpage} and \Com{@outputdblcol} +% by hooking into certain commands inside them +% }% +% +% \begin{macro}{\mph@error} +% Error message if something suspicious happened with the redefintions: +% \begin{macrocode} +\newcommand\mph@error[1]{% + \PackageError{mparhack}{% + Couldn't hook into command `#1' + }{% + This means that a LaTeX version incompatible with + mparhack.sty^^J% + has been used.
