% \section{Introduction}
%
%    The \edmac{} macros \cite{EDMACTUG} for typesetting critical editions 
% of texts
% have been available for use with TeX for some years. Since \edmac{}
% became available there had been a small but constant demand for a
% version of \edmac{} that could be used with LaTeX. The \Eledmac{}
% package was introduced in 2003 in an attempt to satisfy that request.
% 
%    Some critical editions contain texts in more than one form, such as
% a set of verses in one language and their translations in another. In
% such cases there is a desire to be able to typeset the two texts, together
% with any critical apparatus, in parallel. The \Eledpar{} package
% is an extension to \Eledmac{} that enables two texts and their
% apparatus to be set in parallel, either in two columns or on pairs of
% facing pages.
%
%    The package has to try and coerce \TeX{} into paths it was not designed
% for. Use of the package, therefore, may produce some surprising results.
%
% This manual contains a general description of how to use 
% \Eledpar{} starting in section~\ref{howto};
% the complete source code for the package,
% with extensive documentation (in sections~\ref{overview}
% through \ref{end}); 
% and an Index to the source code. As \Eledpar{} is an adjunct to \Eledmac{}
% I assume that you have read the \Eledmac{} manual. Also \Eledpar{} requires
% \Eledmac{} to be used, preferably at least version 0.10 (2011/08/22).
% You do not need to  read the source code for this package in order to 
% use it but doing so may help to answer any questions you might have.
% On a first reading,
% I suggest that you should skip anything after the general documentation in
% sections~\ref{howto} until~\ref{overview}, 
% unless you are particularly interested in the innards of \Eledpar.
%
%
% \section{The \Lpack{\eledpar} package}\label{howto}
%
% A file may mix \emph{numbered} and \emph{unnumbered} text.
% Numbered text is printed with marginal line numbers and can include
% footnotes and endnotes that are referenced to those line numbers:
% this is how you'll want to print the text that you're editing.
% Unnumbered text is not printed with line numbers, and you can't
% use \Eledmac's note commands with it: this is appropriate for
% introductions and other material added by the editor around the
% edited text.
%
% The \Eledpar{} package lets you typeset two \emph{numbered} texts in
% parallel. This can be done either as setting the `Leftside' and `Rightside'
% texts in two columns or on facing pages.
% In the paired pages case footnotes are placed at the bottom of the page
% on which they are called out --- that is, footnotes belonging to the left
% are set at the foot of a left (even numbered) page, and those for right
% texts are at the bottom of the relevant right (odd numbered) page. However,
% in the columnar case, all footnotes are set at the bottom left of the 
% page on which they are called out --- they are not set below the 
% relevant column. 
% The line numbering schemes need not be the same for the two texts.
%
% \subsection{General}
%
% \Eledmac{} essentially puts each chunk of numbered text 
% (the text within a \cs{pstart} \ldots \cs{pend}) into a box and then 
% following the \cs{pend} extracts the text line by line from the box 
% to number and print it. More precisely, the text is first put into the
% the box as though it was being typeset as normal onto a page and
% any notes are stored without being typeset. Then each typeset line 
% is extracted from the box and any notes for that line are recalled.
% The line, with any notes, is then output for printing, possibly with
% a line number attached. Effectively, all the text is typeset and then
% afterwards all the notes are typeset.
% 
%
% \Eledpar{} similarly puts the left and right chunks into boxes but can't 
% immediately output the text after a \cs{pend} --- it has to wait until
% after both the left and right texts have been collected before it can 
% start processing. This means that several boxes are required and possibly
% TeX has to store a lot of text in its memory; both the number of potential
% boxes and memory are limited. If TeX's memory is overfilled the recourse is
% to reduce the amount of text stored before printing.
%
% \DescribeMacro{\maxchunks}
% It is possible to have multiple chunks in the left and right texts before
% printing them. The macro \cs{maxchunks}\marg{num} specifies the maximum
% number of chunks within the left or right texts. This is initially set as: \\
% \verb?\maxchunks{5120}? \\
% meaning that there can be up to 5120 chunks in the left text and up to 
% 5120 chunks in 
% the right text, requiring a total of 10240 boxes. If you need more chunks
% then you can increase \cs{maxchunks}. The \cs{maxchunks} must be called in the preamble.
%
% TeX has a limited number of boxes; if you get an error
% message along the lines of `no room for a new box', then load the package etex, which needs pdflatex or xelatex. If you \cs{maxchunks} is too little
%you can get a \Eledmac{} error message along the
% lines: `Too many \cs{pstart} without printing. Some text will be lost.'
% then you will have to either increase \cs{maxchunks} or use the
% parallel printing commands (\cs{Columns} or \cs{Pages}) more frequently.
%
% When typesetting verse using \cs{syntax}, each line is treated as a chunk,
% so be warned that if you are setting parallel verses you might have to 
% increase \cs{maxchunks} much more than it appears at first sight.
%
%    In general, \Eledmac{} is a TeX resource hog, and \Eledpar{} only 
% makes things worse in this respect.
%
% \section{Parallel columns}\label{columns}
%
% \DescribeEnv{pairs}
% Numbered text that is to be set in columns must be within a \verb?pairs?
% environment. Within the environment the text for the lefthand and righthand
% columns is placed within the \verb?Leftside? and \verb?Rightside? 
% environments, respectively; these are described in more detail below
% in section~\ref{leftright}.
%
% \DescribeMacro{\Columns}
% The command \cs{Columns} typesets the texts in the previous pair of
% \verb?Leftside? and \verb?Rightside? environments. 
% The general scheme for parallel columns looks like this:
% \begin{verbatim}
% \begin{pairs}
% \begin{Leftside} ... \end{Leftside}
% \begin{Rightside} ... \end{Rightside}
% \Columns
% \begin{Leftside} ... \end{Leftside}
% ...
% \Columns
% \end{pairs}
% \end{verbatim}
%
% There is no required pagebreak before or after the columns.
%
% \DescribeMacro{\Lcolwidth}
% \DescribeMacro{\Rcolwidth}
% The lengths \cs{Lcolwidth} and \cs{Rcolwidth} are the widths of the left
% and right columns, respectively. By default, these are: \\
% \verb?\setlength{\Lcolwidth}{0.45\textwidth}? \\
% \verb?\setlength{\Rcolwidth}{0.45\textwidth}? \\
% They may be adjusted if one text tends to be `bulkier' than the other.
%
% \DescribeMacro{\columnrulewidth}
% \DescribeMacro{\columnseparator}
% The macro \cs{columnseparator} is called between each left/right pair
% of lines. By default it inserts a vertical rule of width 
% \cs{columnrulewidth}. As this is initially defined to be 0pt the rule
% is invisible. For a visible rule between the columns you could try: \\
% \verb?\setlength{\columnrulewidth}{0.4pt}? \\
% You can also modify \cs{columnseparator} if you want more control.
% When you use \cs{stanza}, the visible rule may shift when a verse has a hanging indent. To prevent shifting, use \cs{setstanzaindents} outside the \verb|Leftside| or \verb|Rightside| environment.
%
%
% \section{Facing pages}\label{pages}
%
% \DescribeEnv{pages}
% Numbered text that is to be set on facing pages must be within a \verb?pages?
% environment. Within the environment the text for the lefthand and righthand
% pages is placed within the \verb?Leftside? and \verb?Rightside? 
% environments, respectively.
%
% \DescribeMacro{\Pages}
% The command \cs{Pages} typesets the texts in the previous pair of
% \verb?Leftside? and \verb?Rightside? environments. 
% The general scheme for parallel pages looks like this:
% \begin{verbatim}
% \begin{pages}
% \begin{Leftside} ... \end{Leftside}
% \begin{Rightside} ... \end{Rightside}
% \Pages
% \begin{Leftside} ... \end{Leftside}
% ...
% \Pages
% \end{pages}
% \end{verbatim}
% The \verb?Leftside? text is set on lefthand (even numbered) pages and
% the \verb?Rightside? text is set on righthand (odd numbered) pages.
% Each \cs{Pages} command starts a new even numbered page. After parallel
% typesetting is finished, a new page is started.
% 
% \DescribeMacro{\Lcolwidth}
% \DescribeMacro{\Rcolwidth}
% Within the \verb?pages? environment the lengths \cs{Lcolwidth} and 
% \cs{Rcolwidth} are the widths of the left
% and right pages, respectively. By default, these are set to the normal
% textwidth for the document, but can be changed within the environment if
% necessary.
%
% \DescribeMacro{\goalfraction}
% When doing parallel pages \Eledpar{} has to guess where TeX is going to 
% put pagebreaks and hopefully get there first in order to put the pair of
% texts on their proper pages. When it thinks that the fraction 
% \cs{goalfraction} of a page has been filled, it finishes that page and 
% starts on the other side's text. The definition is: \\
% \verb?\newcommand*{\goalfraction}{0.9}? \\
% If you think you can get more on a page, increase this. On the other hand,
% if some left text overflows onto an odd numbered page or some right text
% onto an even page, try reducing it, for instance by: \\
% \verb?\renewcommand*{\goalfraction}{0.8}?
%
% \section{Left and right texts}\label{leftright}
%
% Parallel texts are divided into Leftside and Rightside. The form of the
% contents of these two are independent of whether they will be set 
% in columns or pages.
%
% \DescribeEnv{Leftside}
% \DescribeEnv{Rightside}
% The left text is put within the \verb?Leftside? environment and the 
% right text likewise in the \verb?Rightside? environment. The number of 
% \verb?Leftside? and \verb?Rightside? environments must be the same.
%
% Within these environments you can designate the line numbering scheme(s)
% to be used. 
% \DescribeMacro{\firstlinenum}
% \DescribeMacro{\linenumincrement}
% \DescribeMacro{\firstsublinenum}
% \DescribeMacro{\sublinenumincrement}
% The \Eledmac{} package originally used counters for specifying the 
% numbering scheme; now both \Eledmac\footnote{when used with \Lpack{ledpatch}
% v0.2 or greater.} and
% the \Eledpar{} package use macros instead. Following 
% \cs{firstlinenum}\marg{num} the first line number will be \meta{num}, and
% following \cs{linenumincrement}\marg{num} only every \meta{num}th
% line will have a printed number. Using these macros inside the
% \verb?Leftside? and \verb?Rightside? environments gives you independent 
% control over the left and right numbering schemes. The \cs{firstsublinenum}
% and \cs{sublinenumincrement} macros correspondingly set the numbering
% scheme for sublines.
%
% \DescribeMacro{\pstart}
% \DescribeMacro{\pend}
% In a serial (non-parallel) mode, each numbered paragraph, or chunk, 
% is contained
% between the \cs{pstart} and \cs{pend} macros, and the paragraph is output
% when the \cs{pend} macro occurs. The situation is somewhat different
% with parallel typesetting as the left text (contained within \cs{pstart}
% and \cs{pend} groups within the \verb?Leftside? environment) has to be
% set in parallel with the right text (contained within its own \cs{pstart}
% and \cs{pend} groups within the corresponding \verb?Rightside? environment)
% the \cs{pend} macros cannot immediately initiate any typesetting ---
% this has to be controlled by the \cs{Columns} or \cs{Pages} macros.
% Several chunks may be specified within a \verb?Leftside? or 
% \verb?Rightside? environment.
% A multi-chunk text then looks like:
% \begin{verbatim}
% \begin{...side}
%   % \beginnumbering
%   \pstart first chunk \pend
%   \pstart  second chunk \pend
%   ...
%   \pstart  last chunk \pend
%   % \endnumbering
% \end{...side}
% \end{verbatim}
% Numbering, via \cs{beginnumbering} and \cs{endnumbering}, may extend
% across several \verb?Leftside? or \verb?Rightside? environments. 
% Remember, though,
% that the Left/Right sides are effectively independent of each other.
%
% Generally speaking, controls like \cs{firstlinenum} or \cs{linenummargin}
% apply to sequential and left texts. To effect right texts only they have 
% to be within a \verb?Rightside? environment. 

% If you are using the 
% \Lpack{babel} package with different languages 
% (via, say, \cs{selectlanguage}) for the left and right texts it is 
% particularly important to select the appropriate language within the
% \verb?Leftside? and \verb?Rightside? environments. The initial language
% selected for the right text is the \Lpack{babel} package's default. Also,
% it is the \emph{last} \cs{selectlanguage} in a side that controls the
% language used in any notes for that side when they get printed. If
% you are using multilingual notes then it is probably safest to explicitly
% specify the language(s) for each note rather than relying on the language
% selection for the side. The right side language is also
% applied to the right side line numbers.
%
% Corresponding left and right sides must have the same number of
% paragraph chunks --- if there are four on the left there must be four
% on the right, even if some are empty. The start of each pair of left and
% right chunks are aligned horizontally on the page. The ends may
% come at different positions --- if one chunk is shorter than the other
% then blank lines are output on the shorter side until the end of the longer
% chunk is reached. 
%
% However, sometime if the left pstarts are much greater than right pstarts,
% or \emph{vice-versa},
% you can decide to shift the pstarts on the left and right side.
% That means the start of pstarts are not aligned horizontally on the page,
% the shift is offset at the end of each double pages.
% To enable this function, load eledpar with the option \verb+shiftedpstarts+.
% \section{Numbering text lines and paragraphs}
%
% \DescribeMacro{\beginnumbering}
% \DescribeMacro{\endnumbering}
% Each section of numbered text must be preceded by
% \cs{beginnumbering} and followed by \cs{endnumbering}, like: \\
% \cs{beginnumbering} \\
% \meta{text} \\
% \cs{endnumbering} \\
% These have to be separately specified within \verb?Leftside? and
% \verb?Rightside? environments.
%
% The \cs{beginnumbering} macro resets the line number to zero,
% reads an auxiliary file called \meta{jobname}.\file{nn} (where
% \meta{jobname} is the name of the main input file for this job,
% and \file{nn} is 1 for the first numbered section, 2 for
% the second section, and so on), and then creates a new version of
% this auxiliary file to collect information during this run. 
% Separate auxiliary files are maintained for right hand texts and
% these are named \meta{jobname}.\file{nnR}, using the `R' to distinguish
% them from the left hand and serial (non-parallel) texts.
%
% \DescribeMacro{\memorydump}
% The command \cs{memorydump} effectively performs an \cs{endumbering}
% immediately followed by a \cs{beginnumbering} while not restarting the
% numbering sequence. This has the effect of clearing TeX's memory of previous
% texts and any associated notes, allowing
% longer apparent streams of parallel texts. The command should be applied
% to both left and right texts, and after making sure that all previous
% notes have been output. For example, along the lines of:
% \begin{verbatim}
% \begin{Leftside}
%   \beginnumbering
%   ...
% \end{Leftside}
% \begin{Rightside}
%   \beginnumbering
%   ...
% \end{Rightside}
% \Pages
% \begin{Leftside}
%   \memorydump
%   ...
% \end{Leftside}
% \begin{Rightside}
%   \memorydump
%   ...
% \end{verbatim}
%
% \DescribeMacro{\Rlineflag}
% The value of \cs{Rlineflag} is appended to the line numbers of the
% right texts. Its default definition is: \\
% \verb?\newcommand*{\Rlineflag}{R}? \\
% This may be useful for parallel columns but for parallel pages it might
% be more appropriate to redefine it as: \\
% \verb?\renewcommand*{\Rlineflag}{}?.
%
% \DescribeMacro{\printlinesR}
% \DescribeMacro{\ledsavedprintlines}
% The \cs{printlines} macro is ordinarily used to print the line number 
% references for critical footnotes. For footnotes from right side texts 
% a special version is supplied, called \cs{printlinesR}, which incorporates
% \cs{Rlineflag}. (The macro \cs{ledsavedprintlines} is a copy of the original
% \cs{printlines}, just in case \ldots). As provided, the package makes no
% use of \cs{printlinesR} but you may find it useful. For example, if you only
% use the B footnote series in righthand texts then you may wish to flag
% any line numbers in those footnotes with the value of \cs{Rlineflag}. You
% could do this by putting the following code in your preamble:
% \begin{verbatim}
% \let\oldBfootfmt\Bfootfmt
% \renewcommand{\Bfootfmt}[3]{%
%   \let\printlines\printlinesR
%   \oldBfootfmt{#1}{#2}{#3}}

%\changes{v0.9}{2011/10/01}{Possibility to number \cs{pstart}.}
% It's possible to insert a number at every \cs{pstart} command. You must use the \DescribeMacro{\numberpstarttrue}\cs{numberpstarttrue} command to have it. You can stop the numerotation with \DescribeMacro{\numberpstartfalse}\cs{numberpstartfalse}. You can redefine the commands \DescribeMacro{\thepstartL}\cs{thepstartL} and \DescribeMacro{\thepstartR}\cs{thepstartR} to change style. The numbering restarts on each \cs{beginnumbering}
% \section{Verse}
%
% If you are typesetting verse with \Eledmac{} you can use the \cs{stanza}
% construct, and you can also use this in right or left parallel texts.
% In this case each verse line is a chunk which has two implications.
% (1) you can unexpectedly exceed the \cs{maxchunks} limit or the overall
% limit on the number of boxes, and (2) left and right verse lines are
% matched, which may not be desirable if one side requires more print lines
% for verse lines than the other does.
%
% \DescribeEnv{astanza}
% \Eledpar{} provides an \verb?astanza? environment which you can use instead
% of \cs{stanza} (simply replace \verb?\stanza? by \verb?\begin{astanza}? and
% add \verb?\end{astanza}? after the ending \verb?\&?). Within the 
% \verb?astanza? environment each verse line is treated as a paragraph, 
% so there must be no blank lines in the environment otherwise there will
% be some extraneous vertical spacing.
%
%    If you get an error message along the lines of `Missing number, 
% treated as zero \cs{sza@0@}' it is because you have forgotten to use
% \cs{setstanzaindents} to set the stanza indents.
%
% \DescribeMacro{\skipnumbering}
% The command \cs{skipnumbering} when inserted in a line of parallel text
% causes the numbering of that particular line to be skipped. This can
% useful if you are putting some kind of marker (even if it is only a 
% blank line) between stanzas. Remember, parallel texts must be numbered
% and this provides a way to slip in an `unnumbered' line.
%
%    The \verb?astanza? environment forms a chunk but you may want to
% have more than one stanza within the chunk. Here are a couple of ways of 
% doing that with a blank line between each internal stanza, and with
% each stanza numbered. First some preliminary definitions:
% \begin{verbatim}
% \newcommand*{\stanzanum}[2][\stanzaindentbase]{%
%   \hskip -#1\llap{\textbf{#2}}\hskip #1\ignorespaces}
% \newcommand{\interstanza}{\par\mbox{}\skipnumbering}
% \end{verbatim}
% And now for two stanzas in one. In this first example the line numbering
% repeats for each stanza.
% \begin{verbatim}
% \setstanzaindents{1,0,1,0,1,0,1,0,1,0,1}
% \begin{pairs}
% \begin{Leftside}
%   \firstlinenum{2}
%   \linenumincrement{1}
%   \beginnumbering
%   \begin{astanza}
%     \stanzanum{1} First in first stanza &
%                   Second in first stanza &
%                   Second in first stanza &
%                   Third in first stanza &
%                   Fourth in first stanza &
%     \interstanza
%     \setline{2}\stanzanum{2} First in second stanza &
%                   Second in second stanza &
%                   Second in second stanza &
%                   Third in second stanza &
%                   Fourth in second stanza \&
%   \end{astanza}
%   ...
% \end{verbatim}
% And here is a slightly different way of doing the same thing, but with
% the line numbering being continuous.
% \begin{verbatim}
% \setstanzaindents{1,0,1,0,1,0,0,1,0,1,0,1}
% \begin{pairs}

% \section{Implementation overview}\label{overview}
%
%    TeX is designed to process a single stream of text, which may include
% footnotes, tables, and so on. It just keeps converting its input into
% a stream typeset pages. It was not designed for typesetting two texts
% in parallel, where it has to alternate from one to the other. Further,
% TeX essentially processes its input one paragraph at a time --- it is
% very difficult to get at the `internals' of a paragraph such as the
% individual lines in case you want to number them or put some mark at the
% start or end of the lines.
%
%    \Eledmac{} solves the problem of line numbering by putting the paragraph
% in typeset form into a box, and then extracting the lines one by one 
% from the box for TeX to put them onto the page with the appropriate page
% breaks. Most of the \Eledmac{} code is concerned with handling this box
% and its contents.
%
%    \Eledpar's solution to the problem of parallel texts is to put the two
% texts into separate boxes, and then appropriately extract the pairs of
% lines from the boxes. This involves duplicating 
% much of the original box code for an extra right text box. The other, 
% smaller,
% part of the code is concerned with coordinating the line extractions from
% the boxes.
%
%    The package code is presented in roughly in the same order as in \Eledmac.

%    \end{macrocode}
%  With the option `shiftedpstarts' a long pstart one the left side (or in the right side) don't make a blank on the corresponding pstart, but the blank is put on the bottom of the page. Consequently, the pstarts on the parallel pages are shifted, but the shifted stop at every end of pages.
% The \cs{shiftedverses} is kept for backward compatibility.

% \subsection{Line-number counters and lists}

%
% \begin{macro}{\line@numR}
% \begin{macro}{\subline@numR}
% \begin{macro}{\absline@numR}
% The count \cs{line@numR} stores the line number that's used in
% the right text's marginal line numbering and in notes. 
% The count \cs{subline@numR} stores
% a sub-line number that qualifies \cs{line@numR}. 
% The count \cs{absline@numR} stores the
% absolute number of lines since the start
% of the right text section: that is, the number we've actually printed, 
% no matter what numbers we attached to them.

% \begin{macro}{\insertlines@listR}
% \begin{macro}{\actionlines@listR}
% \begin{macro}{\actions@listR}
% Now we can define the list macros that will be created from the
% line-list file.  They are directly analagous to the left text ones.
% The full list of action codes and their meanings is given in the \Eledmac{}
% manual.
%
% Here are the commands to create these lists:
%
%    \begin{macrocode}
\list@create{\line@listR}
\list@create{\insertlines@listR}
\list@create{\actionlines@listR}

% \subsection{Reading the line-list file}
%
%
% \begin{macro}{\read@linelist}
% \cs{read@linelist}\marg{file} is the control sequence

% (via \cs{line@list@stuff}) to open and process a

% Make sure that the \cs{maxlinesinpar@list} is empty (otherwise things

% in there).
%    \begin{macrocode}

%    \end{macrocode}
% Now get the file and interpret it.
%    \begin{macrocode}
  \get@linelistfile{#1}%
  \endgroup
%    \end{macrocode}
%
% When the reading is done, we're all through with the
% line-list file. All the information we needed
% from it will now be encoded in our list macros.
% Finally, we
% initialize the \cs{next@actionline} and \cs{next@action} macros,
% which specify where and what the next action to be taken is.
%    \begin{macrocode}
  \ifledRcol

%
% This version of \cs{read@linelist} creates list macros

% macro memory limitations.
%
% \subsection{Commands within the line-list file}
%

% We send the paragraph into a box

% the paragraph ends we
% slice the paragraph into its component lines; to each line we
% add any notes or line numbers, add a command to write to the
% line-list, and then at last send the line to the vertical list.
% This section contains all the code for this processing.

% \section{Fixing babel}
%
%    With parallel texts there is the possibility that the two sides
% might use different languages via \verb?babel?. On the other hand,
% \verb?babel? might not be called at all (even though it might be already
% built into the format).
% \changes{v0.2}{2004/12/20}{Added section of babel related code}
%
%    With the normal sequential text each line is initially typeset
% in the current language environment, and then it is output at which
% time its attachments are typeset (in the same language environment.
% In the parallel case lines are typeset in their current language but
% an attachment might be typeset outside the language environment
% of its line if the left and right side languages are different.
% To counter this, we have to make sure that the correct language is
% used at the proper times.
