textdir inside boxes
by Khaled Hosny 18 Apr '09

18 Apr '09

In Aleph, when changin textdir outside a box, the textdir inside the box is not changed. For example: \textdir TRT \setbox0 = \hbox{textdir: \the\textdir , boxdir: \the\boxdir0} \box0 \bye In Aleph, bot will remain TLT. However, in Omega textdir inside the box will get updated to TRT as well. IMO, Omega behaviour makes more sense. The current behaviour just make things more complex. I spent several hours trying to debug why in the following latex example, the second section number is misplaced: \documentclass{article} \begin{document} \section{Test} \textdir TRT\pardir TRT \section{Test} \end{document} I turned out that latex buts section number inside an hbox, which is TLT here.

A native support for SVG
by TeXWorld 18 Apr '09

18 Apr '09

Hello, I'm a ConTeXt (and LaTeX too) user. When I want to make a vector picture, I'm trying most of the time to use programs who can export PGF/TikZ or PStricks. A lot of users like me don't "program" their vector pictures and use wysiwyg programs like Inkscape or Illustrator to generate PStricks ou PGF/TikZ code. Of course whatever program used, we can find a SVG export. SVG is the most spread and the most used format to store vector pictures. I request a native support for SVG in XeTeX and in LuaTeX, I think it would be a great thing. Of course when I want to include SVG pictures in my documents I can convert them to pdf before but the problem is that labels and texts won't be compiled : fonts will be wrong. What do you think about this ? Do you think it's something possible ?

Implementing \pdfmatch via LPEG - opinions?
by David Kastrup 17 Apr '09

17 Apr '09

Hi, I am pondering using \pdfmatch for some application that might eventually be migrated to LuaTeX. My scraps of half-knowledge right of the top of my head indicate that LPEG is compiled into LuaTeX, and that LPEG contains a module that is able to parse regular expression syntax into LPEG. Given those basics, do people see major stumbling blocks for implementing a mostly compatible \pdfmatch as LuaTeX macros? If not, I might just use \pdfmatch in my application and leave the problem of a LuaTeX based implementation for later. All the best, -- David Kastrup
