For various reasons, including its +quality, portability, stability and availability, \TeX{} spread very +rapidly and can nowadays be best described as a world-wide de facto +standard for high quality typesetting. Although it is most famous for +its ability to typeset mathematics, it is being used for many other +types of document, particularly those with multi-lingual requirements. + + + The \TeX{} system is fully programmable. This allows the development +of high-level user interfaces whose input is processed by \TeX{}'s +interpreter to produce low-level typesetting instructions; these are +input to +\TeX{}'s typesetting engine which outputs the format of each page in a +device-independent page-description language. + +Many people have made use of this powerful feature of \TeX{} and +developed their own front-ends; the most commonly used such packages +are \AmSTeX{} and \lamstex{} by Michael +Spivak~\cite{AMS:MSp90,TpC:MSp89} and \LaTeX{} by Leslie +Lamport~\cite{A-W:LLa86}. The development of \AmSTeX{} was sponsored +by the American Mathematical Society, a publishing house which now +processes and typesets the majority of its output using \TeX{}. + + The principal aim of \AmSTeX{} was to simplify the user interface to +the sophisticated built-in math-typesetting capabilities of \TeX{}. +It therefore does not provide support for certain more general +document processing requirements (such as symbolic cross-references, +automatic numbering, etc.); it is therefore most appropriate for short +articles which contain lots of formulas. + +The \LaTeX{} system, on the other hand, supports the needs of long +documents such as textbooks and manuals. It was designed to separate +content and form as much as possible by providing the user with a +generic (i.e.~logical rather than visual) markup interface; this is +combined with style files in which the formatting is specified. +Nevertheless, \LaTeX{} also provides a complete set of direct +formatting instructions; these allow the user to access the full power +of \TeX{}'s typesetting expertise when preparing the final version of +the document. + + Recent years have shown that the concepts and approach of \LaTeX{} +have become widely accepted. Indeed, \LaTeX{} has become the standard +method of communicating and publishing documents in many academic +disciplines. +This has led to many publishers accepting +\LaTeX{} source for articles and books. The American Mathematical +Society, for example, now provides a \LaTeX{} style +option~\cite{AMS:AMSLaTeX90b} which makes the math-typesetting +features of \AmSTeX{} available to users of \LaTeX{}. But the use of +\LaTeX{} in the publishing industry goes further: Elsevier Science +Publishers, for example, +are developing a system~\cite{Cork:NPo91} +which links \SGML{} (for electronic storage of documents in +databases) and \LaTeX{} (for formatting these +documents). + +The use of \LaTeX{}, together with \sgml{}, is now also spreading +into industrial environments, where the technical qualities of \TeX{} +together with the concepts of \LaTeX{} are considered a powerful +combination of great potential importance to such areas as corporate +documentation~\cite{cpc:RWo90} and database +publishing. + + + With the spreading use of SGML-compliant systems, such as the Grif +editor, \LaTeX{} again is a common choice as the formatter for high +quality typeset output~\cite{embull:HLe92}. +A typical SGML Document Type Definition (DTD) uses concepts similar +to those of \LaTeX{}. Therefore, as in the Euromath system, the +formatting is often implemented by simply mapping document elements to +\LaTeX{} constructs rather than directly to `raw +\TeX'~\cite{Kluwer:EvHe90}. +This enables the sophisticated analytical and processing techniques +built in to much of the \LaTeX{} software to be exploited; and it +avoids the need to program in \TeX{}. + +Such developments ensured that the uses of \LaTeX{} have become +widespread, both geographically and typographically. However, they +have also pushed the system way beyond its original intended purpose. +Moreover, as most people who have been involved in the production of +style files will agree, they have demonstrated that the current +version, whilst making the author's job easier, provides little +assistance to developers of new applications. Thus there can be no +doubts about the need for the continued development of \LaTeX{} into a +new, improved, front-end to \TeX{}---one that will serve the +typesetting needs of the nineties and beyond---so that is what we +intend the \LaTeX3 project to provide. + + +\section{History} + +The original goals for the development of a new version of +\LaTeX{} are described +in a paper~\cite{Stanford:MS89} presented in 1989 at the 10th annual +meeting of the \TeX{} Users Group at Stanford---it was also at this +time that Leslie Lamport expressed his full support for such a +project. +However, we have since +discovered that those original goals did not touch many of the +deficiencies of the current system. + +New applications of \LaTeX{} have highlighted many +limitations of its interface (both for authors of documents and for +designers of styles); and further research on such problems +led us to the conclusion +that one gains very little by just providing more and more +specialized style files to solve this or that special problem. +This is because many of these deficiencies and limitations have their +source in \LaTeX{}'s internal concepts and +design~\cite{Stanford:MS89,cahgut:MS90,Cork:MS91}. + +The most important of those original goals, and one that is still a +core part of the \LaTeX3 system and a +central concern of the project team, is the provision of a good +style design interface\Dash one that allows easy +implementation of various layouts. (Easy, of course, is relative: we +mean `as easy as possible, given the complexity of the task'.) +In order to make \LaTeX3 a fully flexible and +extensible system, a major effort is needed in the near future in +order to get this interface `right'. + + + +\section{Aims} + +The principle aims guiding our work on the project's development are +as follows. +\begin{itemize} +\item +The \LaTeX3 system will provide high quality typesetting for +a wide variety of document types and typographic requirements. + \item For authors, it will be easy to use since it will be +highly automated, but controllable. +\item +For editors and designers, it will support the direct formatting +commands which are essential to the fine-tuning of document layout. + \item It will process complex structured documents and + support a document syntax that allows automatic + translation of documents conforming to commonly used + \SGML{} document type definitions + into \LaTeX{} documents\Dash this syntax will therefore, for + example, support the \SGML{} concepts of `attribute' (or + `named argument') + and `short reference', in such a way that these can be easily + linked to the corresponding \SGML{} features. +\item +\LaTeX3 will be designed as an open system and, +like the present version, it will + be usable with any standard \TeX{} system and will thus + be available on a very wide range of platforms. + +\item + Its highly modular design will provide a system that is +flexible and extensible, with well-defined and fully documented +interfaces. + +\item + The code itself will also be thoroughly documented and the + modular design will help to make the system + easy to maintain and enhance. + +\item + We shall also provide extensive catalogues containing many + examples that are carefully designed to make the learning time + for new users (including designers, editors and programmers) + as short as possible. + + \end{itemize} + + + +\section{Available now!} + +In some important +areas, the extra facilities of \LaTeX3 are already +available to current \LaTeX{} users. +\begin{itemize} +\item +The New Font Selection Scheme (NFSS) is now in widespread use, +providing very general and powerful tools for setting up and accessing +all available fonts. A new version (NFSS2) has recently been released, +which extends the flexibility of the system in the following areas of +font management. + +\begin{itemize} +\item + Scalable fonts, e.g., support for PostScript +fonts. +\item +Encodings, i.e., support for multilingual documents allowing change of +font encoding (code page) within a document. + +\item +Math symbols, facilitating access to a wide range of symbols. + +\item +Math typesetting using any suitable family of fonts, eg Lucida or +Adobe Times. + +\end{itemize} + +\item + With \AmSLaTeX{}~\cite{AMS:AMSLaTeX90b} +the capabilities of \LaTeX{} for mathematical typesetting +have reached at least the standard of \AmSTeX. +\item + Work by Frank Mittelbach and David Carlisle, together with valuable +suggestions by several +others, has made available more sophisticated tabular +processing~\cite{unp:MC92}. +\item +Various forms of multiple-column formatting are also now +available~\cite{unp:FMi92}. +\item Johannes Braams~\cite{tub:JBr93} has produced a new version of the +`Babel system' to support a wide range of languages. +\end{itemize} + + + + +\section{New features} +\LaTeX3 will provide much new and enhanced functionality in addition +to the above facilities; and its +`\LaTeX3 programming language' will enable it to be further extended +in a controlled way. + +Here are further details of some of the many planned improvements. + + \begin{itemize} + \item A robust author interface: providing interactive error +recovery linked to an on-line help system. + + \item Languages: +the typesetting will be +customisable for use with different languages +(as will the whole system, \eg the error/help components). +In particular, there will be support for mixed language documents and +for multiple languages within one paragraph to be correctly hyphenated. + + \item Table formatting: a large number of extensions in this area +will be available, including: + \begin{itemize} + \item multi-page tables; + \item automated column width calculation; + \item a variety of designs for ruled tables; + \end{itemize} + +\item Float handling: +the major problem in processing floats (\eg tables and figures) +is the precise specification of +the designer's rules concerning how to position them. The new system +will make it possible to implement a large range of such positioning +algorithms, including the requirements of multi-column formatting, +whilst also supporting explicit positioning commands. + +\item Many of the non-typesetting aspects of document +processing will be automated, providing a +flexible interface to cover a wide range of requirements and styles in +the following areas: + \begin{itemize} + \item citations and bibliographies; + \item cross-references; + \item indexing, etc.; + \item tables of contents, etc.; + \item multiple marks. + \end{itemize} + +\item +The enhanced functionality in the area of mathematical typesetting +will include: + \begin{itemize} + \item alignments in displayed formulas; + \item alphabets, symbols, embellishments; + \item commutative (arrow) diagrams. + \end{itemize} +These will extend many of the features which are +already available in the current version of +\AmSLaTeX{}~\cite{AMS:AMSLaTeX90b}. + +The system will also support the elements defined in the `standard SGML +DTD for mathematical expressions' which is currently under +development~\cite{embull:BSy92}. + +\item The typesetting requirements of many other areas +will also be addressed---some examples: + +\begin{itemize} +\item +technical documentation (\eg offset layout, change bars); +\item +academic publishing in the humanities (\eg critical text editions); +\item +structural formulas in chemistry; +\item +integration of graphical structures, including shading and colour; +\end{itemize} + \end{itemize} + + +\section{Interfaces} + +As we said earlier, the design specification interface is probably +the most significant single new feature of \LaTeX3. It will +have two clearly separated parts: +\begin{itemize} +\item[--] +the creation of the generic mark-up (\eg +environments) used by the author in creating the \LaTeX{} +form of the document; +\item[--] +the specification of how (in \SGML{} language) the document elements +will be formatted. +\end{itemize} +This will simplify the production of different layouts for the same +document type. It will also enable \LaTeX{} documents to be created +and modified by structured document editors, such as Arbortext +Publisher and Grif. Indeed, these two parts are direct analogues of +the following components of the Grif system: the `generic structure +definition (or S) language' and the `presentation description (or P) +language'~\cite{man:GrifL92}. + +However, in order to support the requirements of high quality +typesetting, the \LaTeX3 equivalent of the P language will need to be +even richer than the Grif language. Despite the complexity of the +task, this part of the `designer interface' will help to make the +following straightforward: +\begin{itemize} +\item specification of a wide variety of typographic design rules; +\item linking of the elements in a document type to the desired + formatting; +\item specifying and modifying all of the parameters + that influence the layout. +\end{itemize} + +Another important interface will be the \LaTeX3 programming language, +used for producing enhancements and extensions: it will be an entirely +new language based on data structures and operations suited to the +kind of programming required by document processing applications and +to the expression of visual components of the layout process. Built +on this language there will be high-level generic functions that allow +the straightforward expression of common layout components. + + + +\section{Resources} + +The majority of the work, including conceptualisation, modelling, +prototyping, implementation and testing, +is being undertaken by a dozen individuals under the technical +direction of Frank Mittelbach. +This work is, in most cases including that of the technical director, +done entirely in their spare time and so +involves, as you can imagine, a lot of enthusiasm to keep the +project alive. +A large number of other individuals and organisations have contributed +in one way or another to the effort, and we are confident that this +number will continue to rise. + + There are, nevertheless, many other tasks still to be done in support + of the \LaTeX3 project. These can be worked on concurrently with the + development of the \LaTeX3 kernel system. Furthermore, some of these + tasks require special expertise not found among the core programming + team. Initial research, analysis, and other work on these tasks by + volunteers will, we are sure, greatly speed up the process of + integrating a number of desirable features into \LaTeX3. + +For this reason a `volunteer task list' has been set up: this +describes briefly the individual tasks, which require a wide variety +of expertise and time involvement. It will be updated at regular +intervals and a copy is available, via anonymous {\tt ftp} from `ctan' +sites: {\tt ftp.shsu.edu}, {\tt ftp.dante.de}, {\tt ftp.tex.ac.uk}, in +the directory\\ + {\tt tex-archive/info/ltx3pub}.\\ +For access via mail server, send mail to {\tt +fileserv@shsu.bitnet}, with no subject line and in the body write: +{\tt sendme vol-task}, or to {\tt mail-server@rus.uni-stuttgart.de}, +with no subject line and in the body write: {\tt send +soft/tex/vol-task/vol-task.tex}. If you are unable to retrieve a copy +via electronic networks, please contact Chris Rowley. + +To provide a means of communication with a large number of \LaTeX{} +users an electronic mailing list has been installed at Heidelberg. To +subscribe to this list send a mail message to +\email{listserv@vm.urz.uni-heidelberg.de}, with one line as the body +of the message (substituting your own names): +\begin{verbatim} + subscribe LaTeX-L Your-first-name Your-surname +\end{verbatim} + + +One of the major, and growing, problems is how to bring people from +all over the world together +to discuss the open questions and find new solutions. +It is important that these meetings +involve people from outside the project since we very much +need the views and +experience of typesetters, designers, publishers, etc.\ to help +eliminate the flaws +in the system and to find new and better solutions. + +We have so far held two `open workshops', in London, UK and Boston, +USA; these were hugely successful and showed that further workshops +of this kind are essential if we are to provide \LaTeX3 with a +good designer interface. + +It is now clear that our ability to maintain the current progress +will depend on adequate financial support being available for the +following purposes: +\begin{itemize} + \item enhancement of computer equipment and software for the core + development team; + \item purchase of books on typography and other related subjects; + \item essential expenses (travel, accommodation, etc.) for +meetings of the project's core development team; +and also for meetings with others, for example: testers of early +versions; publishers; typographic designers; suppliers of related + software, etc. +\end{itemize} + + + + + +\section*{References and Bibliography} + +This bibliography contains some items which are not specifically +referenced in this article: these contain further information about the +\LaTeX3 project.
