%%
%% === Installing and Calling ===
%% The file 'fnlineno.sty' is provided ready, installation only requires
%% putting it somewhere where \TeX\ finds it
%% (which may need updating the filename data
%% base).\footnote{\url{http://www.tex.ac.uk/cgi-bin/texfaq2html?label=inst-wlcf}}
%%
%% As usually, 'fnlineno.sty' is loaded by
%% % \begin{verbatim}
%% `\usepackage{fnlineno}'
%% % \end{verbatim}
%% below the `\documentclass' line and before `\begin{document}'.
%%
%% === Limitations ===
%% v0.55 %%% v0.5 %% 2011/02/09
%% should really work
%% the way users expect, %% 2011/02/09
%% but please consider:
%% % In the \strong{present version (v0.4)}, 'flnineno.sty' is just
%% % ``work in progress"---with at least the following issues:
%% \begin{enumerate}
%% % \item Lines are numbered in an order
%% % that you may not like, in the presence of
%% % footnotes.
%% % Overcoming this failure by automagic
%% % will be the major further work on the package!
%% % (v0.5!?)
%% %
%% % \item The package is not expected to work with 'manyfoot'
%% % (neither 'ednotes' ... future work!).
%%
%% \item Nothing is known about compatibility with
%% packages (other than 'manyfoot' and 'bigfoot')
%% providing footnote features beyond standard \LaTeX.
%%
%% \item `\lipsum[<opt-arg>]' in main text produces
%% a different number of paragraphs ...
%%
%% %% 2010/12/18:
%% % \item `\pagebreak' (without optional argument, or
%% % `\pagebreak[4]') in footnotes prints footnote parts
%% % (splits) in wrong order.\footnote{TODO:
%% % (i)~extra case (using flag) in &\output
%% % with $&\outputpenalty=-10000$;
%% % \emph{or}
%% % (ii)~redefine &\pagebreak in footnotes ...}
%% %% 2010/12/19, "tried" "assumed" 2010/12/21:
%% \item v0.41 tried supporting `\pagebreak' in footnotes
%% for manual control of splitting footnotes.
%% %% 2010/12/20f.:
%% However, it wrongly assumed that `\pagebreak[4]'
%% forces a footnote split, cf. Section~\ref{sec:sw};
%% users better still don't use `\pagebreak'
%% in footnotes!
%%
%% \item Much of the code is ``guessed" without complete
%% knowledge of \TeX\ internals and without having
%% tested many possible cases.
%% %% 2010/12/27:
%% \item \emph{Local} switching to ``pagewise" numbering
%% won't be possible for a while; we rather assume
%% that you \emph{always} want ``pagewise" numbering.
%%
%% \item Nothing has been tried to offer choices about the
%% \emph{style} of numbering footnotes.

%% == Implementation ==
%% === Terms ===
%% ``\strong{OTR}" is short for \textit{``output routine"},
%% ``\strong{MVL}" is short for \textit{``main vertical list"}.
%% %%% TODO "acro"
%%
%% === Basic Strategy ===
%% \LaTeX's |\@footnotetext| writes the footnote text into the
%% insertion register. For numbering the footnote lines,
%% \emph{we here} do not execute this `\@footnotetext'
%% immediately after placing |\@footnotemark|,
%% but postpone its |\insert| a little so it
%% is executed only after the main text paragraph has been
%% broken into lines. Right below the line that contains the
%% footnote mark, a special new ``slot" of the \strong{OTR}
%% is called that interchanges ``the page so far" with the
%% footnote text. When the latter has been typeset,
%% another ``slot" of the OTR puts ``the page so far"
%% back to the MVL and immediately after that fills the footnote
%% text as just typeset on the MVL into the `\insert' register.
%%
%% Passing footnotes from horizontal mode to vertical mode
%% resembles 'lineno''s `\PostponeVadjust', but a
%% different \strong{list} |\FNLN@list|
%% must store code
%% (\textit{a})~for the footnote \strong{mark} and
%% (\textit{b})~for the footnote \strong{text}.
%% %%% (TODO: move this paragraph)
%%
%% === Package Options ===

%% ==== Modifying Footnote Commands ====
%% In order to number |\footnote| lines and make

%% In line numbering mode, `\@footnotetext' will act as

%%
%% === ``Continuous'' Numbering ===
%% \label{sec:cont}
%% ==== Goal ====
%% With v0.5, for the first time we try to get a
%% ``pagewise" numbering such that, if a main text line
%% has a footnote,
%% (\textit{i})~its printed number is just the natural
%% successor of the printed number of the previous main
%% text line
%% (instead of continuing previous numbering with the
%% lines of the footnote first),
%% and (\textit{ii})~the printed numbers of footnote lines
%% just continue the printed numbers of the main text lines.
%% This ``obvious'' desirement is not easy to achieve;
%% already pagewise numbering of main text lines,
%% without numbering footnote lines, has been somewhat
%% ingenious.
%%
%% ==== How to Number Lines Pagewise ====
%% The basic idea of 'lineno''s pagewise numbering is:
%% \begin{enumerate}
%% \item Each numbered line of the document is identified
%% by a unique counter value, an ``absolute" number.
%% \item For each page (and column), the range of absolute
%% line numbers occurring on them is recorded
%% (or actually: the first and the last number).
%% \item The ``public," ``human-readable" (``pagewise")
%% format of a given absolute line number $l$ is generated by
%% (\textit{i})~finding the page (and column) with
%% first number $n$ and last number $k$ such that
%% $n\leq l\leq k$,
%% (\textit{ii}) ``printing" $l-n+1$ in ``columnwise"
%% mode, otherwise $l-m+1$ where $m$ is the first
%% absolute line number in the left-hand column of the
%% same page.
%% \end{enumerate}
%% \strong{Generating} the ``pagewise" representation for a
%% given absolute line number $l$ thus may be summarized as
%% \emph{finding the corresponding \emph{\strong{offset}} value}
%% to be subtracted ($n$, $n+1$, $m$, or $m+1$ ...).
%%
%% When \emph{footnote} lines are to be numbered as well,
%% a little problem is the order in which main text and
%% footnote lines increment the absolute counter.
%% 'lineno''s mechanism for this is started immediately
%% after a paragraph has been broken into lines.
%% Each line of the paragraph then calls a macro
%% generating the line number. 'fnlineno' now interrupts
%% numbering of main text lines at a line issuing a footnote.
%% The footnote text is typeset, including numbering its
%% lines at each end of a footnote paragraph. When the
%% footnote text has been sent into the `\insert' register,
%% numbering of main text lines is resumed.
%%
%% Up to v0.4 (a development version), we used the \emph{same}
%% absolute counter for main text and footnote lines.
%% When a page $p$ has more than one main text line and the first
%% one has a long footnote continued on the next page~$p+1$,
%% there is no ``range" of absolute line numbers
%% characterizing page~$p$ any more,
%% because the greatest absolute line number of page~$p$
%% exceeds the absolute line numbers of the footnote continued
%% on page~$p+1$.
%%
%% 'lineno''s procedure can be revived by numbering
%% main text lines and footnote lines independently
%% from each other. We use \emph{two} absolute counters,
%% one is incremented with main text lines only,
%% the other with footnote lines only.
%% Numbering of main text lines just will not be affected
%% by numbering of the footnote lines.
%%
%% Almost the same will hold for footnote lines.
%% Each page (and column) will have a characteristic
%% ``range" of absolute footnote line numbers $\{n,\dots,k\}$.
%% The only notable difference will be that for footnote line~$l$
%% we print $(l-n+1)+(K-N+1) = (K+l)-(N+n)+2$ instead of
%% $l-n+1$---where $\{N,\dots,K\}$ is the range of \emph{main text}
%% line numbers of the page (and column).
%%
%% The previous discussion of \strong{generating} the printed
%% line number from its absolute version
%% has assumed that corresponding \strong{offset} values
%% have been given somehow, or that the ``line number ranges"
%% for pages are known from somewhere.
%% In fact, these ranges are \strong{computed} at the
%% \strong{start} of a \LaTeX\ run \emph{before} typesetting,
%% when reading the `.aux' file for the first
%% time. They are used in the entire document.
%% While typesetting, each numbered line of main text leaves
%% a record of its absolute number and page number in the new
%% version of the `.aux' file that the run creates,
%% a two-parameter macro `\@LN'. With 'fnlineno.sty',
%% there will be new `\@FLN' entries of the same type.
%% These `.aux' entries are used for building
%% the page range data for the next run.
%% When the document source has been changed, at least
%% \emph{two runs} will usually be required
%% to get correct line numbers in page margins,
%% and \emph{another} run will be needed so references
%% to line numbers by `\ref' and `\linelabel' are correct.
%%
%% ==== Summary of Changes ====
%% Variants of 'lineno.sty''s code for ``pagewise"
%% numbering are following. Sometimes we generalize
%% `pagewise' stuff from 'lineno' and re-implement pagewise
%% numbering of main text lines as a special case,
%% the other special case being numbering of footnote lines.
%%
%% Five things need modifications:
%% \begin{description}
%% \item[Building page info macros:]
%% Processing `\@LN' and `\@FLN' `.aux' entries will
%% use shared building macros, the difference is
%% obtained by switching \strong{name spaces}.
%% (It may be notable that a page may get one
%% info macro for main text and another for
%% footnote text, if it contains footnote text.)
%% \item[Logging:]
%% While typesetting, the shared logging macro
%% is switched to write either `\@LN' or `\@FLN'
%% to the `.aux' file. Also, `\c@linenumber'
%% may refer to either the main text or to the
%% footnote text counter.
%% \item[Generating ``pagewise" format:]
%% The choice of `\c@linenumber' also determines
%% which counter is incremented, and again
%% name spaces for page info macros are switched.
%% For footnote lines,
%% a tail macro for adding the number of main text lines
%% will be activated.
%% \item[Referencing:]
%% The `.aux' file may have entries from `\linelabel'
%% containing large numbers from an ``absolute" counter.
%% In generating the ``human-readable" number,
%% it must be known whether it is a main text or a
%% footnote line number.
%% %% 2010/12/28:
%% An additional complication is referring to a
%% main text line from a footnote and vice versa---thinking
%% of global changes in generating the number.
%% Or even think of the case referring from unnumbered text
%% to numbered text!
%% (I have wondered before if the entry couldn't be
%% the ready human-readable number, TODO!)
%% %% 2010/12/27:
%% \item[Lists of ``vertical tasks":]
%% 'lineno.sty' (v4) has introduced two lists of
%% tasks that were issued in horizontal mode
%% but only can be completed after breaking a paragraph
%% into lines: one for `\linelabel's and one for `\vadjust'
%% items that must wait until the line number has been
%% attached. It is essential that the tasks are processed
%% in the same order in vertical mode as they were
%% issued in horizontal mode. As we are now interrupting
%% processing of main text paragraphs for processing
%% footnotes, tasks for footnote text must be lined up
%% in separate lists than tasks for main text.
%% This is indeed essential for the previous issue
%% of getting `\linelabel' work in footnotes as well
%% as in main text.
%% \end{description}
%%
%% ==== Info Building ====
%% % These macros
%% |\@LN|, |\@FLN|, and |\@FNLN|
%% are processed at reading the `.aux' file before typesetting only.
%% The \strong{interface} to \strong{generating}
%% ``pagewise" and footnote line numbers just are |\LN@Pfirst|
%% and |\FLN@Pfirst|, eventually pointing to the first page/column
%% with numbered main text lines or footnote lines, resp.
\def \FLN@Pfirst {\nextLN\relax}
%% This initialization of `\FLN@Pfirst' is just the same
%% as the one of `\LN@Pfirst' in 'lineno.sty';
%% their expansions are changed as soon
%% as such a page is found, replacing the `\relax' by the
%% corresponding page info macro.
%%
%% `\LN@Pfirst' and `\FLN@Pfirst' are passed to
%% |\testFirstNumberedPage| via the hook |\FNLN@first@numbered|
%% that by default is the same as `\LN@first':
\def \FNLN@first@numbered {\LN@Pfirst}
%% (oh, it must be `\def' here to recognize the change ...).
%% This must be changed by `\setfootnotelinenumbers'
%% (`\let' then, as when called the change will have happened).
%%
%% Moreover, they are passed to |\NumberedPageCache|
%% (the page info macro where a search starts,
%% ``current" page/column) as its initialization;
%% the ``generating" macros then change the
%% latter macro following `\nextLN' in the page info macros.
%%
%% In this sense, no other ``name space switching" is needed
%% for communication with other functions.
%%
%% 'lineno.sty' has changed |\LastNumberedPage| globally ...
%% the last page with numbered \emph{footnote} lines
%% may well be another one than the last page with
%% numbered \emph{main} text lines ...
%% But fortunately, also `\LastNumberedPage'
%% is needed in reading the `.aux' before typesetting only
%% (`\@onlypreamble' is \LaTeX's disabling command):
\@onlypreamble\LastNumberedPage
%% In 'lineno.sty', we have `\def\LastNumberedPage{first}'.
%% We need the same for the footnote variant |\FNLN@last@numbered|
%% (to be handled globally!):
\global \let \FNLN@last@numbered \LastNumberedPage
\@onlypreamble \FNLN@last@numbered
%% |\@FNLN{<names>}<last-numbered>{<line>}{<page>}|
%% \\[\smallskipamount]
%% generalizes 'lineno.sty''s `\@LN{<line>}{<page>}'
%% to re-implement it.
%% There is an additional parameter argument <names>
%% for choosing name spaces
%% and a parameter <last-numbered> for choosing the macro
%% storing the ``last numbered page."
%% (An argument without braces expects a macro name.)
\newcommand* \@FNLN [4]{{%
\expandafter\@@LN
\csname #1#4C\@LN@column \expandafter\endcsname
\csname #1O#4\endcsname
{#3}{#4}{#1}{#2}}}
\@onlypreamble\@FNLN
%% As in 'lineno.sty' `\@LN' calls `\@@LN', a new variant
%% of `\@@LN' is called by `\@FLN' here, but it gets one
%% additional parameter for passing <names>
%% and another for passing <last-numbered> from `\@FLN'.
%% So the new syntax is\\[\smallskipamount]
%% |\@@LN<info><first-page-line>{<line>}{<page>}{<names>}<last-numbered>|:
\renewcommand* \@@LN [6]{%
\ifx#1\relax
\ifx#2\relax\gdef#2{#3}\fi
\expandafter\@@@LN\csname #5#6\endcsname#1%
\xdef#1{\lastLN{#3}\firstLN{#3}%
\pageLN{#4}{\@LN@column}{#2}\nextLN\relax}%
\else
\def\lastLN##1{\noexpand\lastLN{#3}}%
\xdef#1{#1}%
\fi
\xdef#6{#4C\@LN@column}}
\@onlypreamble\@@LN
%% 'lineno.sty''s |\@@@LN| does not need any adjustment.
%%
%% 'lineno.sty''s |\@LN{<line>}{<page>}| is reimplemented as
\def \@LN {\@FNLN{LN@P}\LastNumberedPage}
%% ---so `\@LN' really does the same as before, including name spaces.
%%
%% |\@FLN{<line>}{<page>}| is the other special case of the
%% new `\@FNLN'---an `F' precedes the earlier names, and
%% |\FNLN@last@numbered| is the storing macro initialized above:
\def \@FLN {\@FNLN{FLN@P}\FNLN@last@numbered}
%% For logging, we make both unexpandable: %% 2010/12/27
% \AtBeginDocument{\let\@LN\relax \let\@FLN\relax}
%% ... but this way nothing appears in the file!? TODO ...
\@onlypreamble\@LN \@onlypreamble\@FLN
%% For reading the `.aux' finally, we do what
%% 'lineno' does with `\@LN':
\AtEndDocument{\let\@FLN\@gobbletwo}
%%
%% ==== Tool for Reusing Global Operations with Macros ====
%% %% 2010/12/28
%% 'lineno.sty' v4 provides list handling (changing lists globally)
%% and global changes of `\NumberedPageCache'.
%% We want to use them in ``main text" mode
%% as well as in ``footnote" mode.
%% To use such an operation on <ln-macro> for <fln-macro>,
%% we `\global\let<ln-macro><fln-macro>', apply the operations,
%% and finally `\global\let<fln-macro><ln-macro>'.
%% However, we are not only interested in how <fln-macro>
%% is changed this way, rather <ln-macro> also is used as input
%% for some operations, and we can choose which <fln-macro>
%% should be used as input. To switch from working on/with
%% <fln-1> to <fln-2> using <ln-macro> with an option
%% to use <fln-1> later again, a tool
%% |\GStoreUse<ln-macro><fln-1><fln-2>| is provided
%% (should render later switchings much better readable):
\newcommand* \GStoreUse [3]{\global\let#2#1\global\let#1#3}
%% I.e., current content of #1 is stored in #2, then
%% #1 attains the content of #3.
%%
%% ==== General Settings for Typesetting Stage ====
%% % %% 2011/01/01: %% 2011/01/02: wrong!
%% % With 'ednotes', it turns out that the heading is not quite
%% % correct, 'ednotes'' special `\newlabel' mechanism evaluates
%% % `\getpagewiselinelabel' already for building its note
%% % info macros at the first reading of the `.aux' file.
%%
%% %% 2010/12/27:
%% Oh my dear, it seems that all the switching
%% for the footnote variant of `pagewise' must be global
%% (I can't find something useful using `\aftergroup' quickly).
%% Therefore, I render 'lineno''s |\setpagewisenumbers|
%% acting globally:
\renewcommand*\setpagewiselinenumbers{%
\global\let \theLineNumber \thePagewiseLineNumber
\global\let \c@linenumber \c@pagewiselinenumber
\global\let \makeLineNumber \makePagewiseLineNumber
}
%% I just force this, hehe ...
\setpagewiselinenumbers
%% As a counterpart to `\c@pagelinenumber',
%% |\c@footnotelinenumber| is reserved for the
%% absolute footnote line numbers:
\newcount\c@footnotelinenumber
%% %% 2011/01/01 severe-bug fix, why didn't show up?:
%% |\FNLN@@cache| stores `\NumberedPageCache'
%% as from ``main" mode:
\let \FNLN@@cache \NumberedPageCache
%% |\FNLN@cache| stores `\NumberedPageCache'
%% as from ``footnote" mode; its initial content is the
%% counterpart or analogue to `\LN@Pfirst':
\def \FNLN@cache {\FLN@Pfirst}
%% %% 2010/12/28:
%% |\FNLN@foot@cache| and |\FNLN@main@cache|
%% switch |\NumberedPageCache|:
\def \FNLN@foot@cache {%
\GStoreUse \NumberedPageCache \FNLN@@cache \FNLN@cache}
\def \FNLN@main@cache {%
\GStoreUse \NumberedPageCache \FNLN@cache \FNLN@@cache}
%% |\FNLN@labels| will be the counterpart to
%% 'lineno.sty''s `\@LN@labellist':
\global\let \FNLN@labels \@empty
%% |\FNLN@vadjusts| will be the counterpart to
%% 'lineno''s `\@LN@vadjustlist':
\global\let \FNLN@vadjusts \@empty
%% %% separation for referencing 2010/12/28:
%% Settings for footnote line numbers first resemble
%% `\setpagewiselinenumbers'; but more changes
%% are needed, and results from main text numbering
%% must be stored.
%% Some of the settings are needed \emph{locally} for
%% generating numbers for labels, collected in
%% |\setgetfootnotelinenumbers|; for this purpose
%% nothing must be stored explicitly:
\newcommand* \setgetfootnotelinenumbers {%
%% Change of `\theLineNumber' is omitted as we are \emph{reading},
%% not writing a label.
\let\c@linenumber\c@footnotelinenumber
% \let\makeLineNumber\makeFootnoteLineNumber
%% But in fact, |\makeFootnoteLineNumber| and
%% |\makePagewiseLineNumber| will be the same.
%% The difference is made by the choice of
%% |\FNLN@first@numbered| and |\NumberedPageCache|
%% for the line range searches.
\let \FNLN@first@numbered \FLN@Pfirst
\let \FNLN@finish \FNLN@add
}
%% |\setfootnotelinenumbers| performs all the settings
%% for typesetting footnotes in line numbering mode
%% \emph{globally},
%% including storing results from typesetting main text:
\newcommand* \setfootnotelinenumbers {%
\globaldefs\@ne
%% The previous line also renders `\setgetfootnotelinenumbers' global:
\setgetfootnotelinenumbers
%% |\theLineNumber| is used for `\linelabel' entries.
%% `\thePagewiseLineNumber' is replaced by
%% |\theFootnoteLineNumber|:
\let\theLineNumber\theFootnoteLineNumber
%% Logging to `.aux':
\def \FNLN@log {\string\@FLN}%
%% %% 2010/12/28:

}
%% For switching back to ``main text mode,"
%% again some settings may need a local variant---for

%% This is the purpose of |\setgetpagewiselinenumbers|:
\newcommand* \setgetpagewiselinenumbers {%
\let \FNLN@first@numbered \LN@Pfirst
\let \FNLN@finish \@gobbletwo

%% |\unsetfootnotelinenumbers| stores the ``current"

\globaldefs\@ne \setgetpagewiselinenumbers \globaldefs\z@ %% v0.53
\setpagewiselinenumbers
}
%% |\makeFootnoteLineNumber| actually only copies
%% |\makePagewiseLineNumber|, different results are obtained
%% be changing hooks. The command first calls
%% logging---|\logtheLineNumber|,
%% then generating the ``public" line number---|\getLineNumber|
%% (which in turn only is a copy of |\testNumberedPage|
%% in 'lineno.sty').
\@ifdefinable\makeFootnoteLineNumber
{\let \makeFootnoteLineNumber \makePagewiseLineNumber}
%%
%% ==== Logging ====
%% |\logtheLineNumber| is redefined to log both
%% main text and footnote line numbers.
\def \logtheLineNumber {%
\protected@write\@auxout{}{%
\FNLN@log{\the\c@linenumber}{\noexpand\the\c@LN@truepage}}}
%% |\FNLN@log| is the hook for the difference,
%% its default expansion |\@LN| is made for
%% \emph{main text} line numbers:
\gdef \FNLN@log {\string\@LN}
%%
%% ==== ``Public" Line Numbers ====
%% Fortunately, these commands don't need to know much about
%% name spaces. The interfaces to them are
%% |\NumberedPageCache|---changing globally---and
%% |\FNLN@first@numbered|. Our
%% |\FNLN@cache| is initialized
%% by analogy to its counterpart `\NumberedPageCache'
%% (a minute name space change):
\def \FNLN@cache {\FLN@Pfirst}
%% |\testFirstNumberedPage{<integer>}| from 'lineno.sty'
%% is modified by replacing `\LN@Pfirst' only:

%% ==== Referencing ====

%% 'lineno.sty''s `\thePagewiseLineNumber'
%% and `\getpagewiselinenumber{<integer>}'
%% are generalized and re-implemented
%% % by |\theWiseLineNumber| and |\getwiselinenumber|
%% by macros that then serve to implement
%% referring to footnote line numbers.
%%
%% |\theWiseLineNumber{<trans>}| leaves a `\protect'ed call
%% to a one-parameter macro <trans> in the `.aux' file:
\newcommand* \theWiseLineNumber [1]{\protect #1{\the\c@linenumber}}
%% |\getwiselinenumber{<choice>}{<integer>}| executes <choice>
%% before applying `\testNumberedPage' to <integer>---within
%% a local group:
