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)

Hello, under a stable Gentoo I got for dev-tex/luatex-0.63.0 : ... * QA Notice: Package has poor programming practices which may compile * fine but exhibit random runtime failures. * luatexdir/luafontloader/fontforge/fontforge/nouiutil.c:49: warning: attempt to free a non-heap object 'buffer' * Please do not file a Gentoo bug and instead report the above QA * issues directly to the upstream developers of this software. * Homepage: http://www.luatex.org/ ... Hope this helps. -- MfG/Kind regards Toralf Förster pgp finger print: 7B1A 07F4 EC82 0F90 D4C2 8936 872A E508 7DB6 9DA3

draftmode bugs
by Heiko Oberdiek 26 Dec '10

26 Dec '10

Hello, Michael Niedermair reported two bugs in the mailing list TEX-D-L. He used lualatex, but I could reduce it to luatex -ini -draftmode Used version: This is LuaTeX, Version beta-0.65.0-2010121316 (INITEX) 1. draftmode creates output file with zero bytes: \catcode`\{=1 \catcode`\}=2 \directlua{tex.enableprimitives('',{'pdfoutput'})} \pdfoutput=1 \shipout\hbox{} \csname @@end\endcsname\end Result: LuaTeX warning: \pdfdraftmode enabled, not changing output pdf Transcript written on test.log. But test.pdf is created with zero bytes. (It does not matter if a previous test.pdf exists, it will be overwritten.) 2. Image inclusion fails in draft mode: \catcode`\{=1 \catcode`\}=2 \directlua{tex.enableprimitives('',% {'pdfoutput','pdfximage','pdfrefximage','pdflastximage'})% } \pdfoutput=1 \pdfximage{s1.png}\pdfrefximage\pdflastximage \csname @@end\endcsname\end ! LuaTeX error (setup): \pdfdraftmode cannot be changed after data is written to the PDF file. Yours sincerely Heiko Oberdiek

0.60.2 fails to build on armel in CXXLD.sh
by Jani Monoses 21 Dec '10

21 Dec '10

Hello, luatex fails to build on Ubuntu Natty Here is the build log - search for undefined http://launchpadlibrarian.net/58040388/buildlog_ubuntu-natty-armel.luatex_0… Comments on the bug report suggest the parameters are not passed correctly for the static link https://bugs.launchpad.net/ubuntu/+source/gcc-4.5/+bug/686381 Why is a static link needed btw? Does --disable-runtime-cxx-hack have some drawbacks? thanks Jani
