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.

Luatex beta 0.30.2 released
by Taco Hoekwater 20 Oct '08

20 Oct '08

Hi all, I have just uploaded the archives for luatex 0.30.2. This release matches SVN revision #1568. This release fixes a few (rather serious) bugs: * The Lua coco change from 0.30.1 is reverted as it gave trouble on MacOSX. Lua coco on non-intel OpenBSD platforms is now explicitly turned off. * The lua file reading speedup in 0.30.1 broke reading of files larger than 100MB. * Reading of font-related files was broken when there was a find callback, but no read callback. * The texmf.cnf array size setup values were ignored whenever --lua was given on the commandline (instead of only when texconfig.kpse_init is set to false). * glyphs with negative widths resulted in incorrect horizontal placement (overlapping) of the string in the output PDF. * Using \latelua could sometimes result in an invalid output PDF, and the argument token list was expanded too early * There was a read buffer overrun in the mapfile parser * There are two new variables in the status table: status.callbacks and status.indirect_callbacks (execution counts). The archives (source and binaries) can be downloaded from supelec, as usual: http://foundry.supelec.fr/projects/luatex/ Bugs and feature requests can be added to the issue tracker at http://tracker.luatex.org Have fun, Taco _______________________________________________ dev-luatex mailing list dev-luatex(a)ntg.nl http://www.ntg.nl/mailman/listinfo/dev-luatex
