+\section{Introduction}
+\subsection{History}
+To typeset Japanese documents with \TeX, ASCII p\TeX~\cite{ptex} has
+been widely used in Japan. There are other methods---for example, using
+Omega and OTP~\cite{omega}, or with the CJK package---to do so, however,
+these alternative methods did not become a majority. The author thinks
+that this is because p\TeX\ enables us to produce high-quality documents
+(e.g.,~supporting vertical typesetting), and the appearance of p\TeX\ is
+earlier than alternatives described above.
+
+However, p\TeX\ has been left behind from the extensions of \TeX\
+such as \eTeX\ and \pdfTeX, and the diffusion of UTF-8 encoding. In
+recent years, the situation become better, because of developments
+of |ptexenc|~\cite{ptexenc} by Nobuyuki Tsuchimura (\hbox{土村展之}),
+$\varepsilon$-p\TeX~\cite{eptex} by the author,~and up\TeX~\cite{uptex}
+by Takuji Tanaka (田中琢爾). However, continuing this approach, namely, to develop
+an engine extension localized for Japanese, is not wise. This approach
+needs lots of work for \emph{each} engine, and since \LuaTeX\ has an ability
+to hook \TeX's internal process by using Lua callbacks, the necessity of
+an engine extension is getting smaller.
+
+
+There were several experimental attempts to typeset
+Japanese documents with \LuaTeX\ before. Here we cite three examples:
+\begin{itemize}
+\item |luaums.sty|~\cite{luaums} developed by the author. This
+ experimental package is for creating a certain Japanese-based presentation
+ with \LuaTeX.
+\item the \emph{luajalayout} package~\cite{luajalayout}, formerly known as the
+ \emph{jafontspec} package, by Kazuki Maeda (前田一貴). This package is based on
+ \LaTeXe\ and \emph{fontspec} package.
+\item the \emph{luajp-test} package~\cite{luajp-test}, a test package made by
+ Atsuhito Kohda (香田温人), based on articles on the web page~\cite{joylua}.
+\end{itemize}
+However, these packages are based on \LaTeXe, and do not have much
+ability to control the typesetting rule. And it is inefficient that more
+than one people separately develop similar packages. Development of the
+\LuaTeX-ja package is started initially by the author and Kazuki Maeda, because of
+these situations.
+
+\subsection{Development Policy of \LuaTeX-ja}
+\label{ssec-pol}
+The first aim of the \LuaTeX-ja project is to implement features (from the
+'primitive' level) of p\TeX\ as macros under \LuaTeX, so \LuaTeX-ja is
+much affected by p\TeX. However, as development proceeds, some
+technical/conceptual difficulties are arisen. Hence we changed the aim
+of the project as follows:
+\begin{itemize}
+\item\emph{\LuaTeX-ja offers at least the same flexibility of
+ typesetting that p\TeX\ has.}
+
+ We think that the ability of producing outputs conformed to
+ JIS~X~4051~\cite{jisx4051}, the Japanese Industrial Standard for
+ typesetting, or to a technical note~\cite{w3c} by W3C is not enough;
+ if one wants to produce very incoherent outputs for some reason, it
+ should be possible.
+In this point, previous attempts of Japanese typesetting with \LuaTeX\
+ which we cited in the previous subsection are inadequate.
+
+p\TeX\ has some flexibility of typesetting, by changing internal
+ parameters such as |\kanjiskip| or |\prebreakpenalty|, and by using
+ custom JFM (Japanese TFM). Therefore we decided to include these
+ functionality to \LuaTeX-ja.
+
+\item\emph{\LuaTeX-ja isn't mere re-implementation or porting of p\TeX;
+ some (technically and/or conceptually) inconvenient features of
+ p\TeX\ are modified.}
+
+ We describe this point in more detail at the next section.
+\end{itemize}
+
+
+\subsection{Contents of this Paper}
+Here we describe the contents of the rest of this paper briefly. In
+Section~2, we describe major differences between p\TeX\ and \LuaTeX-ja.
+In Section~3, we show the current status of the \LuaTeX-ja package. In
+Section~4, we describe some internal routines of \LuaTeX-ja. We hope
+that the materials in this section have good applications.
+
+\subsection*{About the Project}
+This \LuaTeX-ja project is hosted by SourceForge.jp. The official wiki
+is located on
+\url{http://sourceforge.jp/projects/luatex-ja/wiki/FrontPage}. There is
+no stable version at Oct.\ 15, 2011, however the development source can be
+obtained from the git repository. Members of the project are as follows
+(in random order): Hironori Kitagawa, Kazuki Maeda, Takayuki Yato,
+Yusuke Kuroki, Noriyuki Abe, Munehiro Yamamoto, Tomoaki Honda,
+and~Shuzaburo Saito.
+
+
+\section{Major differences with \pTeX}
+In this section, we look at several major differences between p\TeX\
+and our \LuaTeX-ja. For general information of Japanese typesetting and the
+overview of p\TeX, please see Okumura~\cite{ptexjp}.
+
+
+\subsection{Names of Control Sequences}
+\label{ssec-csname} Since p\TeX\ is an engine modification of Knuth's
+original \TeX82 engine, some primitives added by it take a form that is
+very difficult to be simulated by a macro. For example, an additional
+primitive |\prebreakpenalty|$\langle\hbox{\it
+char\_code}\rangle$|[=]|$\langle\hbox{\it penalty}\rangle$ in p\TeX\
+sets the amount of penalty inserted before a character whose code is
+$\langle\hbox{\it char\_code}\rangle$ to $\langle\hbox{\it
+penalty}\rangle$, and this form |\prebreakpenalty|$\langle\hbox{\it
+char\_code}\rangle$ can be also used for retrieving the value.
+
+Moreover, there are some parameters which values of them at the end of a
+horizontal box or that of a paragraph are effective in whole box or
+paragraph. These parameters were implemented as additional internal
+parameters in \pTeX. However, the implementation of these parameters in
+\LuaTeX-ja is not so easy; we will discuss on it in
+Subsection~\ref{ssec-stack}.
+
+From above 2~problems we discussed above, the assignment and retrieval
+of most parameters in \LuaTeX-ja are summarized into the following
+3~control sequences:
+\begin{itemize}
+\item |\ltjsetparameter{|$\langle\hbox{\it
+ name}\rangle$|=|$\langle\hbox{\it value}\rangle$|,...}|: for local
+ assignment.
+\item |\ltjglobalsetparameter|: for global assignment. These two control
+ sequences obey the value of |\globaldefs| primitive.
+\item |\ltjgetparameter{|$\langle\hbox{\it
+ name}\rangle$|}[{|$\langle\hbox{\it optional
+ argument}\rangle$|}]|: for retrieval. The returned value is always
+ a string.
+\end{itemize}
+
+\subsection{Line-break after a Japanese Character}
+\label{ssec-line}
+
+Japanese texts can break lines almost everywhere, in contrast with
+alphabetic texts can break lines only between words (or use
+hyphenation). Hence, p\TeX's input processor is modified so that a
+line-break after a Japanese character doesn't emit a space. However,
+there is no way to customize the input processor of \LuaTeX, other than
+to hack its CWEB-source. All a macro package can do is to modify an input line before
+when \LuaTeX\ begin to process it, inside the |process_input_buffer|
+callback.
+
+Hence, in \LuaTeX-ja, a comment letter (we reserve U+FFFFF for this
+purpose) will be appended to an input line, if this line ends with a Japanese
+character\footnote{Strictly speaking, it also requires that the catcode
+of the end-line character is 5~(\emph{end-of-line}). This condition is
+useful under the verbatim environment.}. One might jump to a conclusion
+that the treatment of a line break by p\TeX\ and that of \LuaTeX-ja are
+totally same, however they are different in the respect that \LuaTeX-ja's
+judgement whether a comment letter will be appended the line is done
+\emph{before} the line is actually processed by \LuaTeX.
+
+Figure~\ref{fig-linebreak} shows an example of this situation; the
+command at the first line marks most of Japanese characters as
+`non-Japanese characters'. In other words, from that command onward, the
+letter `あ' will be treated as an alphabetic character by
+\LuaTeX-ja. Then, it is natural to have a space between `あ' and `y' in
+the output, where the actual output in the figure does not so. This is
+because `あ' is considered a Japanese character by \LuaTeX-ja,
+when \LuaTeX-ja does a decision whether U+FFFFF will be added to the
+input line~2.
+

+\caption{A notable sample showing the treatment of a line break after a
+Japanese character.}\label{fig-linebreak}
+\end{figure}
+
+\subsection{Separation between `real' fonts and Metrics}
+\label{ssec-sepmet}
+
+Traditionally, most Japanese fonts used in typesetting are not
+proportional, that is, most glyphs have same size (in most cases,
+square-shaped). Hence, it is not rare that the contents of different
+JFMs are essentially same, and only differ in their names. For example,
+|min10.tfm| and |goth10.tfm|, which are JFMs shipped with p\TeX\ for
+seriffed \emph{mincho} family and sans-seriffed \emph{gothic} family,
+differ their |FAMILY| and |FACE| only. Moreover, |jis.tfm| and
+|jisg.tfm|, which consists a parts of \emph{jis} font metric, which is
+used in \emph{jsclasses}~\cite{jsclasses} by Haruhiko Okumura (奥村晴彦),
+are totally same as binary files. Considering this situation, we
+decided to separate `real' fonts and metrics used for them in
+\LuaTeX-ja. Typical declarations of Japanese fonts in the style of plain
+\TeX\ are shown in Figure~\ref{fig-jfdef}. We would like to add several
+remarks:
+\begin{itemize}
+\item A control sequence |\jfont| must be used for Japanese fonts, instead of |\font|.
+\item \LuaTeX-ja automatically loads the \emph{luaotfload} package, so
+ |file:| and |name:| prefixes, and various font features can be
+ used as the line~1 in Figure~\ref{fig-jfdef}.
+\item The |jfm| key specifies the metric for the font. In
+ Figure~\ref{fig-jfdef}, both fonts will use a metric stored in a
+ Lua script named |jfm-ujis.lua|. This metric is the standard
+ metric in \LuaTeX-ja, and is based on JFMs used in the \emph{otf}
+ package~\cite{otf}.
+\item The |psft:| prefix can be used to specify name-only, non-embedded
+ fonts. When one display a pdf with these fonts, actual fonts which
+ will be used for them depend on a pdf reader.
+\end{itemize}
+The specification of a metric for \LuaTeX-ja is similar to that of a JFM
+(see \cite{ptexjp}); characters are grouped into several classes, the
+size information of characters are specified for each class, and
+glue/kern insertions are specified for each pair of classes. Although
+the author have not tried, it may be possible to develop a program that
+`converts' a JFM to a metric for \LuaTeX-ja. \LuaTeX-ja offers three
+metrics by default; |jfm-ujis.lua|, |jfm-jis.lua| based on the
+\emph{jis} font metric, and |jfm-min.lua| based on old |min10.tfm|.
+
+ Note that |-kern| in features
+is important, since kerning information from real font itself will
+clash with glue/kern informations from the metric.
+

+\caption{Typical declarations of Japanese fonts.}

+
+\subsection{Insertion of Kerns and/or Glues for Japanese Typesetting: the Timing}
+\label{ssec-jglue}
+
+As described in \cite{luatexref}, \LuaTeX's kerning and ligaturing
+processes are totally different from those of \TeX82. \TeX82's process is
+done just when a (sequence of) character is appended to the current
+list. Thus we can interrupt this process by writing as
+|f{}irm|. However, \LuaTeX's process is \emph{node-based}, that is, the
+process will be done when a horizontal box or a paragraph is ended, so
+|f{}irm| and |firm| yield same outputs under \LuaTeX.
+
+The situation for Japanese characters is more complicated.
+Glues (and kerns) which are needed for Japanese
+typesetting will be divided into the following three categories:
+\begin{itemize}
+\item Glue (or kern) from the metric of Japanese fonts (\emph{JFM glue},
+ for short).
+
+\item Default glue between a Japanese character and an alphabetic
+ character (\emph{xkanjiskip}, for short), usually 1/4 of
+ full-width (\emph{shibuaki}) with some stretch and shrink for
+ justifying each line.
+\item Default glue between two consecutive Japanese characters
+ (\emph{kanjiskip}, for short). The main reason of this glue is to
+ enable breaking lines almost everywhere in Japanese texts. In most
+ cases, its natural width is zero, and some stretch/shrink for
+ justifying each line.
+\end{itemize}
+In p\TeX, these three kinds of glues are treated differently. A JFM glue
+is inserted when a (sequence of) Japanese character is appended to the
+current list, same as the case of alphabetic characters in \TeX82. This
+means that one can interrupt the insertion process by saying |{}|. A
+\emph{xkanjiskip} is inserted just before `hpack' or line-breaking of a
+paragraph; this timing is somewhat similar to that of \LuaTeX's kerning
+process. Finally, A \emph{kanjiskip} is not appeared as a node anywhere;
+only appears implicitly in calculation of the width of a horizontal box,
+that of breaking lines, and the actual output process to a DVI
+file. These specifications made p\TeX's behavior very hard to
+understand.
+
+\LuaTeX-ja inserts glues in all three categories simultaneously inside
+|hpack_filter| and |pre_linebreak_filter| callbacks. The reasons of
+this specification are to behave like alphabetic characters in \LuaTeX\
+(as described in the first paragraph), and to clarify the specification
+for \LuaTeX-ja's process.

+\label{fig-ptexjfm}
+\end{figure}
+
+Now we will take a look inside the insertion process itself, and describe 4~points.
+
+\begin{description}
+\item[Ignored Nodes]
+As noted in the previous subsection, the insertion process in p\TeX\ can
+ be interrupted by saying |{}| or anything else\footnote{This
+ is why some tricks like \texttt{ちょ\char`\{\char`\}っと} for
+ \texttt{min10.tfm} and other `old' JFMs work.}. This leads
+ the second row in Table~\ref{tab-jfmglue}, or
+ Figure~\ref{fig-ptexjfm}. `The process is interrupted' means
+ that p\TeX\ does not think the letter `】\inhibitglue' is
+ followed by `\inhibitglue【', hence two half-width glues are
+ inserted between between `】\inhibitglue' and `\inhibitglue【',
+ where one is from `】\inhibitglue' and another is from
+ `\inhibitglue【'.
+
+ On the other hand, in \LuaTeX-ja, the process is done inside
+ |hpack_filter| and |pre_linebreak_filter| callbacks. Hence,
+ \emph{anything that does not make any node will be
+ ignored}\ in \LuaTeX-ja, as shown in (1) in
+ Table~\ref{tab-jfmglue}. \LuaTeX-ja also ignores any nodes
+ which does not make any contribution to current horizontal
+ list---\emph{ins\_node}, \emph{adjust\_node},
+ \emph{mark\_node}, \emph{whatsit\_node} and
+ \emph{penalty\_node}---, as shown in (4).
+
+
+By the way, around a \emph{glyph\_node} $p$ there may be some nld odes
+ attached to $p$. These are an accent and kerns for
+ positioning it, and a kern from the italic
+ correction\footnote{\TeX82 (and \LuaTeX) does not distinguish
+ between explicit kern and a kern for italic correction. To
+ distinguish them, an additional subtype for kern is introduced
+ in p\TeX. On the other hand, \LuaTeX-ja uses an additional attribute and
+ redefines \texttt{\char`\\/}.} for $p$. It is natural that
+ these attachments should be ignored inside the process. Hence
+ \LuaTeX-ja takes this approach, as the latest version of
+ p\TeX\ (p3.2). This explains (2) in the figure.
+
+Summerizing above, one should put an empty horizontal box |\hbox{}| to
+ where he wants to interrupt the insertion process in
+ \LuaTeX-ja as (3) in the figure.
+
+\item[Fonts with the Same Metric]
+Recall that \LuaTeX-ja separated `real' fonts and metrics, as in Subsection~\ref{ssec-sepmet}.
+Consider the following input, where all Japanese fonts use same metric
+ (in \LuaTeX-ja), and |\gt| selects \emph{gothic} family for
+ the current Japanese font family:
+\begin{quote}
+\begin{verbatim}
+明朝）\gt （ゴシック
+\end{verbatim}
+\end{quote}
+If the above input is processed by p\TeX, since the insertion process is
+ interrupt by |\gt|, the result looks like
+\begin{quote}
+\mc 明朝）\hbox{}\gt （ゴシック
+\end{quote}
+However this seems to be unnatural, since two Japanese fonts in the
+ output use the same metric, i.e.,~the same
+ typesetting rule. Hence, we decided that Japanese fonts with
+ the same metric are treated as one font in the insertion
+ process of \LuaTeX-ja. Thus, the output from the above input
+ in \LuaTeX-ja looks like:
+\begin{quote}
+\mc 明朝）\gt （ゴシック
+\end{quote}
+One might have the situation that this default behavior is not
+ suitable. \LuaTeX-ja offers a way to cope with this case, but
+ we leave it to the manual~\cite{man}.
+
+\item[Fonts with Different Metrics]
+In the case where two consecutive Japanese characters use different metrics and/or
+ different size is similar. Consider the following input where
+ the \emph{mincho} family and the \emph{gothic} family use
+ different metrics:
+\begin{quote}
+\begin{verbatim}
+漢）\gt （漢）\large （大
+\end{verbatim}
+\end{quote}
+As the previous paragraph, this input yields the following, by p\TeX:
+\begin{quote}
+\mc 漢）\hbox{}\gt （漢）\hbox{}\large （大
+\end{quote}
+We thought that amounts of spaces between parentheses in above output
+ are too much. So we changed the default behavior of
+ \LuaTeX-ja so that the amount of a glue between two Japanese
+ characters with different metrics is the average of a glue
+ from the left character and that from the right
+ character. For example, Figure~\ref{fig-diffmet} shows the
+ output from above input. The width of glue indicated `(1)' is
+ $(a/2 + a/2)/2 = 0.5a$, and the width of glue indicated `(2)'
+ is $(a/2 + 1.2a/2)/2 = 0.55a$. This default behavior can be
+ changed by \textsf{diffrentmet} parameter of \LuaTeX-ja.

+\end{center}
+\caption{Fonts with different metrics.}
+\label{fig-diffmet}
+\end{figure}
+
+\item[\emph{kanjiskip} and \emph{xkanjiskip}]
+In p\TeX, the value of \emph{xkanjiskip} is controlled by a skip named
+ |\xkanjiskip|. A defect of this implementation is that the
+ value of \emph{xkanjiskip} is not connected with the size of
+ the currnt Japanese font. It seems that |EXTRASPACE|,
+ |EXTRASTRETCH|, |EXTRASHRINK| parameters in a JFM are
+ reserved for specifying the default value of
+ \emph{xkanjiskip} in a unit of the design size, but p\TeX\
+ did not use these parameters.
+
+Considering this situation of p\TeX, \LuaTeX-ja can use the value of
+ \emph{xkanjiskip} that specified in a metric. If the value of
+ \emph{xkanjiskip} on user side (this is the
+ \textsf{xkanjiskip} parameter in |\ltjsetparameter|) is
+ |\maxdimen|, then the \LuaTeX-ja use the specification from
+ the current used metric as the actual value of
+ \emph{xkanjiskip}.
+This description also applies for \emph{kanjiskip}.
+\end{description}
+
+
+\section{Current Status of Development}
+At the moment, \LuaTeX-ja can be used under plain \TeX, and under
+\LaTeXe. Generally speaking, one only has to read |luatexja.sty|, by |\input|
+command or |\usepackage| (in~\LaTeXe), if you merely want to typeset
+Japanese characters. We look more detail by parts.
+
+\subsection{`Engine Extension'}
+The lowest part of \LuaTeX-ja corresponds the p\TeX\ extension as
+\emph{an engine extension of \TeX}. We, the project menbers, think that
+this part is almost done. Other features of \LuaTeX-ja which we have not
+described are the followings:
+\begin{description}
+\item[Setting the Range of `Japanese characters'] This feature is
+ inspired by up\TeX. up\TeX\ has an additional primitive named
+ |\kcatcode| for setting how a character is treated among an
+ alphabetic character, \emph{kana}, \emph{kanji},
+ \emph{Hangul}, or~\emph{an other CJK character}. and the
+ assignment of |\kcatcode| can be done by a Unicode
+ block\footnote{There are some exceptions. For example,
+ U+FF00--FFEF (Halfwidth and Fullwidth Forms) are divided into
+ three blocks in recent up\TeX.}.
+
+\LuaTeX-ja uses a slightly different approach. Because there are many
+ Unicode blocks already in Basic Multilingual Plane which are
+ not included in most Japanese fonts, so it would be
+ inefficient to toggle by a Unicode block. Furthermore, the
+ basic Japanese character set JIS~X~0208 are not just union of
+ Unicode blocks; for example, the intersection of JIS~X~0208
+ and Latin-1 Supplement is shown in Table~\ref{tab-inter}.
+ Considering these two points, to customize the range of
+ Japanese characters in \LuaTeX-ja, one has to define
+ character ranges in his source in advance.
+
+\item[Shifting Baseline]
+In order to make a match between Japanese fonts and alphabetic fonts,
+ sometimes shifting the baseline of alphabetic characters may
+ be needed. p\TeX\ has a dimension |\ybaselineshift|, which
+ corresponds the amount of shifting down the baseline of alphabetic
+ characters. This is useful for Japanese-based documents, but
+ not for documents mainly in languages with alphabetic
+ characters.
+
+Hence, \LuaTeX-ja extends p\TeX's |\ybaselineshift| to Japanese
+ characters. Namely, \LuaTeX-ja offers two parameters,
+ \textsf{yjabaselineshift} and \textsf{yalbaselineshift}, for the
+ amount of shifting the baseline of Japanese characters and
+ that of alphabetic characters, respectively.

+\subsection{Patches for plain \TeX\ and \LaTeXe}
+p\TeX\ has a patch for plain \TeX, namely |ptex.tex|, that for \LaTeXe\
+macro (this patch and \LaTeXe\ consist \emph{p\LaTeXe}), and
+|kinsoku.tex| which includes the default setting of \emph{kinsoku
+shori}, the Japanese hyphenation. We ported them to \LuaTeX-ja, except
+the codes related to vertical typesetting, since \LuaTeX-ja doesn't
+support vertical typesetting yet. We remark two points related to the
+porting:
+\begin{description}
+\item[Default Range of Japanese Characters]
+As described in the previos subsection, \LuaTeX-ja can customize the
+range of Japanese characters. \LuaTeX-ja predefines 8~character ranges,
+as shown in Table~\ref{tab-chrrng}. Almost of these ranges are just the
+union of Unicode blocks, and determined from the Adobe-Japan1-6 character
+collection~\cite{aj16}, and JIS~X~0208. And, among these 8~ranges, the
+ ranges~2, 3, 6, 7, and~8 are considered ranges of Japanese
+ characters, and others are considered ranges of alphabetic
+ characters.
+
+This default setting is suitable for Japanese-based documents, however it
+ causes that other packages which use Unicode fonts do not work
+ correctly. For example, |\times| provided by the
+ |unicode-math| package is the character U+00D7, which belongs
+ to the range~8, and |\textendash| provided by the |EU2|
+ encoding used in the \emph{fontspec} package is the
+ character U+2013, which belongs to the range~3. hence, these
+ character cannot be typeset correctly with the default range setting.
+
+\begin{table}
+\caption{Predefined ranges in \LuaTeX-ja}
+\label{tab-chrrng}
+\begin{center}
+\begin{tabular}{@{\bf}rl}
+1&(Additional) Latin characters which is not belonged in the range~8.\\
+2&Greek and Cyrillic letters.\\
+3&Punctuations and miscellaneous symbols.\\
+4&Unicode blocks which does not intersect with Adobe-Japan1-6.\\
+5&Surrogates and supplementary private use Areas.\\
+6&Characters used in Japanese typesetting.\\
+7&Characters possibly used in CJK typesetting, but not in Japanese.\\
+8&Characters in Table~\ref{tab-inter}.
+\end{tabular}
+\end{center}
+\end{table}
+
+
+\item[Behavior of\/ {\tt\char92fontfamily\/}]
+The control sequence |\fontfamily| in p\LaTeXe\ changes the current alphabetic
+ font family and/or the current Japanese font family,
+ depending the argument. More concretely,
+ |\fontfamily{|$\langle\hbox{\it arg\/}\rangle$|}| changes the
+ current alphabetic font family to $\langle\hbox{\it
+ arg\/}\rangle$, if and only if one of the following
+ conditions are satisfied:
+\begin{itemize}
+\item An alphabetic font family named $\langle\hbox{\it arg\/}\rangle$ in
+ \emph{some} alphabetic encoding already defined in the document.
+\item There exists an alphabetic encoding $\langle\hbox{\it
+ enc\/}\rangle$ already defined in the document such that a font
+ definition file $\langle\hbox{\it enc\/}\rangle\langle\hbox{\it
+ arg\/}\rangle$|.fd| exists.
+\end{itemize}
+The same criterion is used for changing Japanese font family.
+
+To work this behavior well, a list of all (alphabetic) encodings defined
+ already in the document is needed. However, since \LuaTeX-ja
+ is loaded as a package, \LuaTeX-ja cannot have this list.
+ Hence \LuaTeX-ja adopted a different approach, namely
+ |\fontfamily{|$\langle\hbox{\it arg\/}\rangle$|}| changes the
+ current alphabetic font family to $\langle\hbox{\it
+ arg\/}\rangle$, if and only if:
+\begin{itemize}
+\item An alphabetic font family named $\langle\hbox{\it arg\/}\rangle$ in
+ the current alphabetic encoding $\langle\hbox{\it enc\/}\rangle$.
+\item A font definition file $\langle\hbox{\it enc\/}\rangle\langle\hbox{\it
+ arg\/}\rangle$|.fd| exists.
+\end{itemize}
+
+
+\end{description}
+
+
+
+\subsection{Classes for Japanese Documents}
+To produce `high-quality' Japanese documents, we need not only that
+Japanese characters are correctly placed, but also class files for
+Japanese documents. In p\TeX, there are two major families of classes:
+\emph{jclasses} which is distributed with the official p\LaTeXe\ macros,
+and \emph{jsclasses}. At the present, \LuaTeX-ja
+simply contains their counterparts: \emph{ltjclasses} and
+\emph{ltjsclasses}. However, the policy on classess is not determined
+now, and we hope to have another family of classes which are useful in
+commercial printing. In the author's opinion, \emph{ltjclasses} is
+better to stay as an example of porting of class files for \pTeX\ to
+\LuaTeX-ja.
+
+\subsection{Patches for Packages}
+Apart from patches for the \LaTeXe~kernel and classes for Japanese
+documents, we need to make patches for several packages. At the present,
+we considered the following packages, and made patches or porting for
+the former two packages.
+
+\begin{description}
+\item[The \emph{fontspec} package] The \emph{fontspec} package is built
+ on NFSS2, hence control sequences offered by the
+ \emph{fontspec} package, such as |\setmainfont|, are only
+ effective for alphabetic fonts if \LuaTeX-ja is loaded. The
+ optional package \texttt{luatexja-\penalty0fontspec.sty}
+ offers these counterparts for Japanese fonts, with additional
+ `j' in the name of control sequences, such as
+ |\setmainjfont|.
+
+\item[The \emph{otf} package]
+This package is widely used in p\TeX\ for characters which is
+not in JIS~X~0208, and for using more than one weight in \emph{mincho}
+and \emph{gothic} font families. Therefore \LuaTeX-ja supports features
+in the \emph{otf} package, by loading \texttt{luatexja-\penalty0otf.sty}
+ manually. Note that characters by |\UTF{xxxx}| and
+ |\CID{xxxx}| are not appended to the current list as a
+ \emph{glyph\_node}, so they are not affected by callbacks by
+ the \emph{luaotfload} package. We have another remark; |\CID|
+ does not work with TrueType fonts.
+
+\item[The \emph{listings} package]
+It is well-known that there is a patch |jlisting.sty| of the
+ \emph{listings} package for p\LaTeXe. Generally speaking, it
+ also can be used in \LuaTeX-ja. However, it seems to be that
+ a Japanese character after a space does not recieve any
+ process of the \emph{listings} package; this is inconvinient
+ when we use the \emph{showexpl} package.
+\end{description}
+
+
+
+\section{Implementation}
+\subsection{Handling of Japanese Fonts}
+In p\TeX, there are three slots for maintaining current fonts, namely
+|\font| for alphabetic fonts, |\jfont| for Japanese font (in horizontal
+direction) and |\tfont| for Japanese font (in vertical direction). With
+these slots, we can manage the current font for alphabetic characters
+and that for Japanese characters separately in p\TeX. However, \LuaTeX\
+has only one slot for maintaining the current font, as \TeX82. This
+situation leads a problem: how can we maintain the `current Japanese
+font'?
+
+There are three approaches for this problem. One approach is to make a
+mapping table from alphabetic fonts to corresponding Japanese fonts
+(here we don't assume that NFSS2 is available). Another approach is
+that we always use composite fonts with alphabetic fonts and Japanese
+fonts. The third approach is that the information of the current
+Japanese font is stored in an attribute. We adopted the third approach,
+since \LuaTeX-ja is much affected by p\TeX\ as we noted in
+Subsection~\ref{ssec-pol}.
+
+As in Figure~\ref{fig-jfdef}, \LuaTeX-ja uses |\jfont| for defining
+Japanese font, as p\TeX. However, since the information of the current
+Japanese font is stored into an attribute, control sequences defined by
+|\jfont| (e.g.,~|\foo| and |\bar| in Figure~\ref{fig-jfdef}) is
+not representing a font by the means of \TeX82. In other words, each of
+these control sequences is just an assignment to an attribute, therefore
+they cannot be an argument of |\the|, |\fontname|, or |\textfont|.
+
+\subsection{Overview of the Processes}
+Now we describe an outline of the \LuaTeX-ja's process briefly.
+\begin{description}
+\item[Treatment of Line-breaks after a Japanese Character] This part is
+ described already in Subsection~\ref{ssec-line}. Done in the
+ |process_input_buffer| callback.
+\item[Font Replacement] In the |hyphenate| callback, \LuaTeX-ja looks
+ into for each \textit{glyph\_node}~$p$ in the list. If the
+ character represented by $p$ is considered as a Japanese
+ character, the font used in $p$ is replaced by the value of
+ |\ltj@curjfnt|, `the current Japanese font' at~$p$. Also the
+ character class of the character is looked up at this time.
+
+Furthermore the subtype of $p$ is subtracted by 1 to suppress
+ hyphenation around it by \LuaTeX, since later processes of
+ \LuaTeX-ja take care of all things about Japanese characters.
+\end{description}
+%
+Following processes are all executed in |pre_linebreak_filter| and
+|hpack_filter| callback. These processes are main routines of \LuaTeX-ja.
+
+\begin{description}
+\item[Examination of Stack Level] The horizontal list which
+ is the content of a horizontal box is traversed,
+to determine what is the level of \LuaTeX-ja's internal stack at the end
+ of the list. This is needed because of the place of
+ the |hpack_filter| callback in the source of \LuaTeX. We will discuss more
+ detail in Subsection~\ref{ssec-stack}.
+
+\item[Insertion of Glues/Kerns for Japanese Typesetting]
+This part is already described at Subsection~\ref{ssec-jglue}.
+
+\item[Adjustument of the Position of (Japanese) Characters]
+We will discuss the detail about this in Subsection~\ref{ssec-width}.
+\end{description}
+
+The callbacks by the \emph{luaotfload} package, e.g.,~replacement of
+glyphs according to font features, are executed just after `Examination
+of Stack Level' above.
+
+\subsection{Stack Management}
+\label{ssec-stack}
+
+As we noted in Subsection~\ref{ssec-csname}, parameters that the values
+at the end of a horizontal box or that of a paragraph are effective in
+whole box or paragraph, such as \emph{kanjiskip}, cannot be implemented
+by internal integers or registers of other types in \TeX. We explain it
+in this section.
+
+\begin{figure}
+\begin{lstlisting}
+void package(int c)
+{
+ ...
+ d = box_max_depth;
+ unsave();
+ save_ptr -= 4;
+ if (cur_list.mode_field == -hmode) {
+ cur_box = filtered_hpack(cur_list.head_field,
+ cur_list.tail_field, saved_value(1),
+ saved_level(1), grp, saved_level(2));
+ subtype(cur_box) = HLIST_SUBTYPE_HBOX;
+ } else {
+\end{lstlisting}
+\caption{An extract of a CWEB-source \texttt{tex/packaging.w} of \LuaTeX}
+\label{fig-ltsrc}
+\end{figure}
+
+Figure~\ref{fig-ltsrc} is an extract of a CWEB-source
+\texttt{tex/packaging.w} of \LuaTeX\ (SVN revision 4358). This function
+is called just when an explicit |\hbox{...}| or |\vbox{...}| is ended, and
+the function |filtered_hpack()| is where the |hpack_filter| and then the
+actual `hpack' process are performed. Notice that the |unsave()|
+function is called before |filtered_hpack()|. This is the problem;
+because of |unsave()|, we can retrive only the values of registers
+\emph{outside} the box, even in the |hpack_filter| callback.
+
+To cope with this problem, \LuaTeX-ja has its own stack system, based on
+Lua codes in \cite{stack-mail}. Furthermore, \emph{whatsit} nodes whose
+\emph{user\_id} is 30112 (\emph{stack\_node}, for short) will be
+appended to the current horizontal list each time the current stack
+level is incremented, and their values are the values of
+|\currentgrouplevel| at that time. In the beginning of the |hpack_filter|
+callback, the list in question is traversed to determine whether the
+stack level at the end of the list and that outside the box coincides.
+
+Let $x$ be the value of |\currentgrouplevel|, and $y$ be the current
+stack level, both inside the |hpack_filter| callback, i.e.,~outside a
+horizontal box. Consider a list which represents the content of the box,
+then we have:
+\begin{itemize}
+\item A \emph{stack\_node} whose value is $x+1$ (since all materials in
+ the box are included in a group |\hbox{...}|, the value is at
+ least $x+1$) in the list represents an assignment related to the
+ stack system in just top-level of the list, like
+\begin{quote}
+\begin{verbatim}
+\hbox{...(assignment)...}
+\end{verbatim}
+\end{quote}
+In this case, the current stack level is incremented to $y+1$ after the assignment.
+\item A \emph{stack\_node} whose value is more than $x+1$ in the list represents
+an assignment inside another group contained in the box. For example,
+ the following input creates
+a \emph{stack\_node} whose value is $x+3=(x+1)+2$:
+\begin{quote}
+\begin{verbatim}
+\hbox{...{...{...(assignment)}...}...}
+\end{verbatim}
+\end{quote}
+\end{itemize}
+Thus, we can conclude that the stack level at the end of the list is
+$y+1$, if and only if there is a \emph{stack\_node} whose value is
+$x+1$. Otherwise, the stack level is just $y$.
+
+\subsection{Adjustment of the Position of Japanese Characters}
+\label{ssec-width}
+
+The size of a glyph specified in a metric and that of the real font
+usually differ. For example, the letter `\inhibitglue【' is half-width
+in |jfm-ujis.lua| or |jis.tfm|, while this letter is full-width like `【'
+in most TrueType fonts used in Japanese typesetting, such as
+IPA~Mincho. Hence the adjustment of position of such glyphs is
+needed. In the context of p\TeX, this process was performed using virtual fonts.
+
+On the other hand, Lua\TeX-ja does the adjustment by encapsuling a glyph
+into a horizontal box. There are two main reasons why we adopted this
+method; one is that we feared Lua codes for coexisting with callback by
+|luaotfload| package would be large if we use virtual fonts, and the
+other is to cope with the shifting of the baseline of characters at the
+same time.

+\end{picture}
+\end{center}
+\caption{The position of the `real' glyph.}
+\label{fig-pos}
+\end{figure}
+
+Figure~\ref{fig-pos} shows the adjustment process. A large square $M$ is
+the imaginary body which is specified in the metric, and a vertical
+rectangle is the imaginary body of a real glyph. First, the real glyph
+is aligned with respect to the width of $M$. In the figure, the real
+glyph is aligned `middle'; this setting is useful for the full-width
+middle dot `・'. We have other settings, namely, `left' and `right'.
+After that, it is shifted according to the value of |left| and |down|,
+which are specified in the metric. The final position of the real glyph
+is shown by the gray rectangle~$R$. If the amount of shifting the baseline is
+not zero, $M$ (and hence the real glyph) is shifted by that amount.
+
+We would like to remark briefly about the vertical position of a glyph.
+A JFM (or the metric used in \LuaTeX-ja) and the real font used for it
+may have different height or depth. In that case, it may look better if
+the real glyph is shifted vertically to match the height-depth ratio
+specified in the metric. This situation is carefully studied by
+Otobe~\cite{min10}. Here the policy on this problem is not determined
+now, however we want to offer several solutions by \LuaTeX-ja.
+
+\section{Conclusion}
+We have discussed about our \LuaTeX-ja package, which is much affected
+by p\TeX. For now, it can be used for experimental use, however there
+are much refinements which are needed for regular use. The author hopes
+that this paper and this project contribute the typesetting Japanese,
+and possibly other Asian languages, under \LuaTeX.

+Lua\TeX-ja は，p\TeX と同等あるいはそれ以上の水準の日本語組版を，
+次世代標準\TeX エンジンであるLua\TeX で可能にすることを目的とした，開発中のマクロパッケージである．
+本発表では，Lua\TeX-ja の現在の状況について，p\TeX との相違点を中心に報告する．
+
+\section{開発方針}
+\begin{itemize}
+\item \emph{最低でもp\TeX と同等の組版の自由度を確保する．}
+p\TeX のprimitiveに相当するレベルから開発を行う．
+\item \emph{p\TeX との100\%互換は目的としない．}
+p\TeX において不自然/不都合な実装があれば，積極的に改める．
+\end{itemize}
+
+
+\section{p\TeX との主な違い}
+\subsection{縦書きはまだ未実装}
+落ち着いてきたら縦書きも開発したいが，現状は左横書きのみに集中している．
+
+\subsection{命令名称の変更}
+大半のパラメタへの代入は\:{ltjsetparameter}へ
+{\tt \.{key}=\.{value}}の形で渡す．
+
+例：行頭禁則用ペナルティ({\sf prebreakpenalty})
+\begin{center}\medskip\small%
+\begin{tabular}{lll}
+\toprule
+&p\TeX&Lua\TeX-ja\\\midrule
+代入&\:{prebreakpenalty}\.{chr}{\tt =}\.{pena}&
+\verb+\ltjsetparameter{prebreakpenalty={+\.{chr}{\tt,}\.{pena}\verb+}}+\\
+取得&\:{prebreakpenalty}\.{chr}（count）&
+\verb+\ltjgetparameter{prebreakpenalty}{+\.{chr}\verb+}+（string）\\
+\bottomrule
+\end{tabular}
+\end{center}
+\
+
+\subsection{行末が和文文字の場合の改行の扱い}
+Lua\TeX の仕様上，「前行行末時の設定値」で判定するad hocな仕様．
+%1行を外部から読み込むとき，前行行末のcatcodeの状態で，行の末尾が次の形のときに改行を無視する：
+%\[
+% \hbox{(catcodeが11 or 12の和文文字)}\hbox{(catcodeが1 or 2の文字)}^*
+%\]
+
+\subsection{和文間・和欧文間の空白挿入処理}
+p\TeX のそれをベースに，1から書き直しを行った．
+\begin{enumerate}
+\item 空白挿入処理をノードベースに変更（Lua\TeX の合字・カーニング処理に合わせた）．
+\item \inhibitglue「和文フォント」はメトリックと実際の字形，そしてサイズとの組で定義される：
+\begin{center}
+$\tt\mathcode`\:="703A\mathcode`\*="7020
+\mathcode`\=="703D\mathcode`\-="702D\mathcode`\|="705C%"
+\mathcode`\<="707B\mathcode`\>="707D
+|jfont|tenmin=\underbrace{\tt psft:Ryumin-Light}_{\text{PostScriptフォント（非埋込）}}:%
+\underbrace{\tt jfm=ujis}_{\text{メトリック}}*at*13.5|jQ
+$\smallskip
+\end{center}
+空白挿入処理では，メトリックとサイズの同じ和文フォントは同一視される．
+
+\item 異なるメトリック・サイズの2つの和文文字の間には，両メトリックから決まる空白の平均値が入る．
+\end{enumerate}
+
+\begin{center}\medskip\small%
+\begin{tabular}{ccc}
+\toprule
+\textbf{入力}&\textbf{p\TeX}&\textbf{Lua\TeX-ja}\\\midrule
+$
+\tt\mathcode`\:="703A\mathcode`\*="7020
+\mathcode`\=="703D\mathcode`\-="702D\mathcode`\|="705C%"
+\mathcode`\<="707B\mathcode`\>="707D
+あ\overbrace{\tt）<|gt（}^{\text{2.}}い
+\overbrace{\tt）<>（}^{\text{1.}}>う\overbrace{\tt）<|Large（}^{\text{3.}}え>
+$
+&\large あ）\hbox{}{\gt（い）\hbox{}（}う）\hbox{}{\Large（え}&
+\large あ）{\gt（い）{}（}う）{\Large（え}\\
+\bottomrule
+\end{tabular}
+\end{center}
+\
+
+\section{現在の実装状況}
+\subsection{\inhibitglue 「エンジン拡張部分」%
+\centerbaseline{\scriptsize\normalfont}{（\TeX\inhibitglue →\inhibitglue p\TeX のエンジン拡張部分
+に相当）}}\ \par概ね実装済みであるが，細かい仕様変更の可能性あり．また，
+従来ではprimitiveとして実装されていた機能をLuaコードと\TeX マクロを用いて実装しな
+いといけないので，予想外のバグの可能性があるとともに，処理速度が非常に遅い．
+
+\subsection{\LaTeXe への対応
+\centerbaseline{\scriptsize\normalfont}{（p\LaTeXe 実装に相当）}}\ \par
+p\LaTeXe のソースを参考に，NFSS2へのパッチなど主な部分の実装は行った．
+まだ自前の日本語用クラスファイルは製作しておらず，
+八登さんによるBXjsclsを使用するのが現状では手っ取り早い．
+\centerbaseline{\scriptsize\normalfont}{（本文書も同クラスを使用している）}
+
+
+\subsection{{\tt fontspec}, {\tt otf}パッケージの対応}\ \par
+\verb+\setmainjfont+, \verb+\CID+など一部の機能が実装され，ある程度は使える状況である．
