For the -last few releases of \TeX~Live, the experimental programming foundation for -\LaTeX3 has been available under the name \package{expl3}. Despite large -warnings that the code would probably change in the future, we wanted to show -that there was progress being made, no matter how slowly. Since then, some -people have looked at the code, provided feedback, and~--- most -importantly~--- actually tried using it. Although it is yet early days, we -believe that the ideas behind the code are sound and there are only `cosmetic -improvements' that need to be made before \package{expl3} is ready for the -\LaTeX~package author masses. - -\section{What currently exists} - -The current \LaTeX3 code consists of two main branches: the -\package{expl3} modules that define the underlying programming environment, -and the `\package{xpackage}s', which are a suite of packages that are written -with the \package{expl3} programming interface and provide some higher-level -functionality for what will one day become \LaTeX3 proper. Both \package{expl3} and -parts of the \package{xpackages} are designed to be used \emph{on top} of -\LaTeXe, so new packages can take advantage of the new features while still -allowing to be used alongside many of the vast number of \LaTeXe\ packages on -\textsc{ctan}. - -\section{What's happening now} - -In preparation for a minor overhaul of the \package{expl3} code, we are -writing a comprehensive test suite for each module. These tests allow us to -make implementation changes and then test if the code still works as before. -They are also highlighting any minor shortcomings or omissions in the code. -As the tests are being written, our assumptions about what should be called -what and the underlying naming conventions for the functions and datatypes are -being questioned, challenged, and noted for further rumination. - -At the time of writing, we are approximately half-way through writing the test -suite. Once this task is complete, which we plan for the first -half of 2009, we will be ready to make changes without worrying about breaking -anything. - -\section{What's happening soon} - -So what do we want to change? The current \package{expl3} codebase has -portions that date to the pre-\LaTeXe\ days, while other modules have been -more recently conceived. It is quite apparent when reading through the sources -that some unification and tidying up would improve the simplicity and -consistency of the code. In many cases, such changes will mean nothing more -than a tweak or a rename. - -Beyond these minor changes, we are also re-thinking the exact notation behind -the way functions are defined. There are currently a handful of different -types of arguments that functions may be passed (from an untouched single -token to a complete expansion of a token list) and we're not entirely happy -with how the original choices have evolved now that the system has grown -somewhat. We have received good feedback from several people on ways that we -could improve the argument syntax, and as part of the upcoming changes to the -\package{expl3} packages we hope to address the problems that we currently -perceive in the present syntax. - -\section{What's happening later} - -After the changes discussed above are finished, we will begin freezing the core -interface of the \package{expl3} modules, and we hope that more package -authors will be interested in using the new ideas to write their own code. -While the core functions will then remain unchanged, more features and new -modules will be added as \LaTeX3 starts to grow. - -Some new and/or experimental packages will be changing to use the -\package{expl3} programming interface, including \package{breqn}, -\package{mathtools}, \package{empheq}, \package{fontspec}, and -\package{unicode-math}. (Which is one reason for the lack of progress in -these latter two in recent times.) There will also be a version of the -\package{siunitx} package written in \package{expl3}, in parallel to the -current \LaTeXe\ version. These developments will provide improvements to -everyday \LaTeX\ users who haven't even heard of The \LaTeX{} Project. - -Looking towards the long term, \LaTeX3 as a document preparation system needs -to be written almost from scratch. A high-level user syntax needs to be -designed and scores of packages will be used as inspiration for the -`out-of-the-box' default document templates. \LaTeXe\ has stood up to the test -of time~--- some fifteen years and still going strong~--- and it is now time -to write a successor that will survive another score. - -\end{document} -- cgit v1.2.3
