Snapshot 20070307
by Taco Hoekwater 10 May '12

10 May '12

Hi all, I decided to do a snapshot now instead of waiting for friday, because I want to start concentrating on something else besides font support issues. What's new: * Non-CID PostScript-based Opentype fonts are now combined over the entire document, and properly subsetted. The code is borrowed from xdvipdfmx with some minor adjustments Adding support for CID-keyed OpenType fonts would not be hard but at the moment I lack example input (and incentive). * A small extension to the virtual fonts structure: you can use f.fonts[1] = { 'id' = 38} to do a backreference to a previously defined font. This saves quite a few computations * There was a bug in the handling of \leaders in the output whereby it's width was taken to be twice what it should be while writing to the PDF, fixed now. * The font inclusion code is cleaned up a bit by Hartmut. * Some compilation problems were fixed. * There is (quite a bit of) debugging information printed out when OTPs are in use, because I am tracking down a bug reported by Idris. The input of each and every OTP step is shown on the terminal in a line line this: [57902][1568][58423][1568][58408][1568][58921] those are the decimal values of ocp i/o characters. If you don't need them, don't worry about it. Happy TeXing, Taco ----- Downloading and installation details: If you go to https://foundry.supelec.fr/frs/?group_id=10 you will see that there are three new released files: * luatex-snapshot-20070307.tar.bz2 This is the source tree. * luatex-snapshot-20070307-win32.zip A cross-compiled (mingw) windows binary. This is a web2c based binary, so it needs a texmf.cnf file (It will NOT work if you have only miktex installed). * luatex-snapshot-20070307-linux-i386.tar.bz2 An intel 32 linux binary (2.6.17)

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 ?

Traversing node list
by Khaled Hosny 30 Oct '08

30 Oct '08

I'm wondering why, in the following code, the first \hbox{} is not seen by the lua function while the second one is seen i.e. \hbox{} at paragraph beginning isn't seen. \directlua0{ local function traverse(h) for n in node.traverse (h) do texio.write_nl('node id='..node.type(n.id)) if n.id == node.id('hlist') then traverse(n.list) end end end callback.register('pre_linebreak_filter', function(h) traverse(h) return true end ) } \hbox{Not seen} Hello \hbox{seen} \bye Regards, -- Khaled Hosny Arabic localizer and member of Arabeyes.org team

How to build luatex on Ubuntu 8.04 desktop?
by dhj 29 Oct '08

29 Oct '08

I want to build luatex-beta-0.30 on my Ubuntu 8.04. I run ./build.sh or ./build.sh.linux, it return error. ~/luatex-beta-0.30.0$ ./build.sh Your make is a GNU-make; I will use that ignore warnings and errors about the main texmf tree checking whether make sets $(MAKE)... yes checking for gcc... gcc checking for C compiler default output file name... configure: error: C compiler cannot create executables See `config.log' for more details. My gcc version is: :~/luatex-beta-0.30.0$ gcc -v Using built-in specs. Target: i486-linux-gnu Configured with: ../src/configure -v --enable-languages=c,c++,fortran,objc,obj-c++,treelang --prefix=/usr --enable-shared --with-system-zlib --libexecdir=/usr/lib --without-included-gettext --enable-threads=posix --enable-nls --with-gxx-include-dir=/usr/include/c++/4.2 --program-suffix=-4.2 --enable-clocale=gnu --enable-libstdcxx-debug --enable-objc-gc --enable-mpfr --enable-targets=all --enable-checking=release --build=i486-linux-gnu --host=i486-linux-gnu --target=i486-linux-gnu Thread model: posix gcc version 4.2.3 (Ubuntu 4.2.3-2ubuntu7) Could anyone tell me what's the problem? Thanks!

string library with utf-8 support
by Olivier Binda 28 Oct '08

28 Oct '08

Hello, I developped a Japanese dictionnary in XeTeX. It compiles just fine in luatex but I would like to code the commands in Lua instead of TeX. To make the code faster, cleaner, simpler and more powerfull. Yet, I need to be able to manipulate utf-8 strings (find, substring, replace, length, etc...). Is there a simple way to do that in LUA ? Will there be one day a luatex library for utf8 string managments ? (because it seems the string library is just for strings with 1 byte characters and it is really lacking) Keep up the good work. Olivier Binda
