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)

Can \directlua be nested?
by Jonathan Sauer 01 Feb '08

01 Feb '08

Hello, can \directlua be nested, i.e. \directlua0{\directlua0{tex.print('foo()')}} to call Lua function 'foo'? Of course this example is contrived, but I could imagine the situation where Lua code is created by TeX macros which in turn use \directlua). Thanks in advance, Jonathan

reimplementing various scripts in texlua
by Norbert Preining 18 Jan '08

18 Jan '08

Hi Lua Gurus, we are planning to reimplement various scripts which are at the core of TeX Live (and many other TeX distributions) in texlua. I guess all of you know what we are talking about: mktexlsr, updmap, fmtutil, mktexupd, mktexnam, ... As a finger exercise in lua programming I started implementing mktexupd. Ok, it is not perfect, but AFAIS it does the same as the shell scripts. If one or more of you want to give a helping hand (much appreciated) please take a look at the telxive-svn, trunk/Master/tlpkg/texlua: http://www.tug.org/svn/texlive/trunk/Master/tlpkg/texlua/ and send me scripts, or check them in yourself, or just go over the scripts and fix bugs, etc etc. Any help is appreciated. Not that I say we will get these scripts running by TL2008, but for TL2009 it would be nice.

Wishlist interactive shell
by Norbert Preining 18 Jan '08

18 Jan '08

Hi Taco, is it complicated to add an interactive shell to texlua? I mean I don't need readline support or all the stuff, but playing around on a console would be fun. If this is too much bloat I am fine without it.

os.exec and waiting for process
by Norbert Preining 18 Jan '08

18 Jan '08

Dear Taco, dear all, Reinhard Kotucha wrote a support script in texlua but there is a strange thing: os.exec(...) does not wait for the process to terminate. Now my question is: Is there any way to do that, i.e., to call a different program and wait for it to terminate, resembling the perl 'system' call. Thanks a lot and all the best Norbert ------------------------------------------------------------------------------- Dr. Norbert Preining <preining(a)logic.at> Vienna University of Technology Debian Developer <preining(a)debian.org> Debian TeX Group gpg DSA: 0x09C5B094 fp: 14DF 2E6C 0307 BE6D AD76 A9C0 D2BF 4AA3 09C5 B094 ------------------------------------------------------------------------------- DUNBOYNE (n.)

luatex and context for Debian
by Norbert Preining 06 Jan '08

06 Jan '08

Dear all, I have updated luatex and context so currently I can even run MkIV documents ;-) Debian/sid users should have them already. Debian/etch users should get luatex 0.20.2-1 from deb http://people.debian.org/~preining/TeX/ luatex/ deb-src http://people.debian.org/~preining/TeX/ luatex/ Currently I have only i386 packages, but will build amd64 for etch soon. And maybe powerpc builds can be organized. For context 2007.12.18-1 please add deb http://people.debian.org/~preining/TeX/ context/ deb-src http://people.debian.org/~preining/TeX/ context/ Just for completeness, it is good to have: texlive: deb http://people.debian.org/~preining/TeX/ tl2007/ deb-src http://people.debian.org/~preining/TeX/ src/ latin modern: deb http://people.debian.org/~preining/TeX/ lmodern/ deb-src http://people.debian.org/~preining/TeX/ lmodern/ For Ubuntu users of the development version (i.e., that tracking sid more or less) luatex can be found at deb http://people.debian.org/~preining/TeX/ luatex-sid/ deb-src http://people.debian.org/~preining/TeX/ luatex-sid/ Please comment if you find something missing.
