This process has -made the status of different modules clearer, so that both the team themselves -and everyone else know what is going on. - -The `Big Bang' changes were not shipped to \textsc{ctan} until after the \TeX{} -Live 2011 freeze, as we did not want to end up with a \textsc{dvd} containing -badly broken code. The update went to \textsc{ctan} soon after \TeX{} Live 2011 -shipped, and has now propagated around the world. The new package naming -(\pkg{l3kernel}, \pkg{l3packages} and \pkg{l3experimental}) has caused some -surprises for a small number of users, but there have not been any major -issues with the changes at the code level. - -The `Big Bang' has attracted attention from programmers outside of the -\LaTeX3 team, with useful feedback arriving on the -\texttt{LaTeX-L} list and TeX.sx, in particular. One area that this has -highlighted is the need to document carefully when changes to the `stable' -parts of the \LaTeX3 codebase occur. All changes to \pkg{l3kernel} now -come with an explicit date for the change in the documentation, which means -that programmers can check exactly when the features they want were introduced. - -Another key part of supporting \LaTeX3 use beyond the team is making it easy -to check on the version of \LaTeX3 installed. To support that, the file date -of the main \pkg{expl3} package is now set each time there is a release of the -\LaTeX3 material to \textsc{ctan}. This means that the \LaTeXe{} -\cs{@ifpackagelater} test can be used reliably to detect if the installed -version of \LaTeX3 is going to supply the functions that a programmer is -using. - -\section{Deforming boxes} - -Additions to both the \LaTeX3 stable material and more experimental modules -continue. Joseph Wright has been working on adding `native' drivers for -\LaTeX3 to support box transformations. These allow box rotation, clipping -and scaling with the drivers \texttt{dvips}, \texttt{xdvipdfmx} and direct -\textsc{pdf} output. - -The development of clipping support for the \texttt{xdvipdfmx} driver has also allowed -us to suggest improvements to the \LaTeXe{} graphics drivers, enabling clipping -with the \XeTeX{} engine. - -\section{A \TeX{}-based regex engine} - -Bruno Le Floch has been %working across the codebase, %% omitted to avoid page break -improving the efficiency -and robustness of a number of \LaTeX3 functions. Most notably, he has -created a purely \TeX{}-based regular expression (regex) system for \LaTeX3. -This is currently experimental, but is already proving useful and will -hopefully stabilise over the coming months. - -Bruno's regex system works with all of the supported engines (pdf\TeX{}, -\XeTeX{} and \LuaTeX{}). He has implemented the core ideas of standard -regex systems, along with some \TeX{}-specifics to allow matching and -replacing -the content of token lists % correct? -by category code. - -\section{\pkg{xparse} improves} - -The \pkg{xparse} module has been overhauled, making the internal code -more efficient and adding additional argument types. This has also allowed -us to deal with a number of internal bugs, meaning that argument grabbing -is now more reliable. - -The argument grabbers themselves have been reworked so that in the event of an error, -the user will normally get a meaningful message from \TeX{} rather than -one pointing to \pkg{xparse} internal function names. This should help -in tracking down erroneous input in real documents. - -\section{The galley} - -As detailed in the last issue, work on the galley module has been continuing. -Discussion of Joseph's reimplementation of the galley concepts highlighted -some important areas to work on, with the nature of the template concept -being particularly significant. - -More work is still needed to finalise the galley concepts, but it is clear that -some of this will require feedback from other areas. Joseph therefore hopes -to finish work on the current round of galley improvements by the end of -February, and to return to them once some other areas have been addressed. - -\section{Relationships between document items} - -The \textsc{tug}2011 meeting took place in October in India. Frank Mittelbach -spoke there about ideas for describing the design relationship between document elements. -% omit calling it "ldb" here because that name will likely change (last I heard?) -These ideas allow a document designer to specify the design of a document element -based on its context within a document, and progress in this area will likely -lead to an extension in the \pkg{xtemplate} system. - -\end{document} |
