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 ?

Commit messages in Cron Daemon
by Giuseppe Bilotta 30 Jul '08

Hello all, would it be possible to enhance the Cron Daemon commit emails by adding the commit message for every logged commit? Just having a list of changed files is nowhere as interesting as knowing what the changes were for :) Thanks, -- Giuseppe "Oblomov" Bilotta

0.29: Overlapping lines with OTF
by Jonathan Sauer 30 Jul '08

30 Jul '08

Hello, when using OpenType fonts with beta 0.29, all lines are typeset at the same height, thus overlapping each other. This does not happen with T1 fonts nor with beta 0.27.0. I have attached the PlainTeX test file as well as the result in 0.27 and 0.29. Thanks in advance, Jonathan

Can't find file without extension
by Manuel Pégourié-Gonnard 29 Jul '08

29 Jul '08

Hi, I just tried the following: mpg@siegel:~% echo '\\bye' > foobar mpg@siegel:~% pdftex foobar This is pdfTeXk, Version 3.1415926-1.40.9 (Web2C 7.5.7) %&-line parsing enabled. entering extended mode (./foobar ) No pages of output. Transcript written on foobar.log. mpg@siegel:~% luatex foobar This is LuaTeX, Version snapshot-0.25.4-2008071722 (Web2C 7.5.7) ! I can't find file `foobar.tex'. <*> foobar Please type another input file name: Looks like luatex doesn't want to eat files without extensions, while pdftex accepts them. Is it a feature? Manuel.

ecrm1000
by Javier Bezos 28 Jul '08

28 Jul '08

I think this question has popped up before, but I couldn't find it. When I try to typeset any LaTeX document with the default T1 fonts, I get the following error: ! Font \T1/cmr/m/n/10=ecrm1000 at 10pt not loadable: metric data not found or bad. LuaTeX finds the file (as kpse.find_file shows) and in fact it should find it, because I have a copy in the local directory. If I switch to another font (ae, mathmazo, etc.) it works fine and I was able to typeset several documents by using the process_input_buffer to convert the 8-bit input to a pseudo utf8 text which can be applied inputenc to (ie, with active characters). Just a dirty trick, of course, but it worked. Another question. Has someone attempted to make LuaTeX/LaTeX compatible with existing T1 and the like fonts? (without using active characters, I mean). After reading the manual for 0.29 I've inferred this part is still under development. I'm reading the lua files from ConTeXt, so I presume I'll have more questions soon. Any further pointers? I'm interested mainly in LaTeX (LuaLaTeX?). Thanks Javier ------------------------- http://www.tex-tipografia.com

Core Dumped While Compiling Impatient
by Yue Wang 28 Jul '08

28 Jul '08

Hi, Taco, LuaTeX cored (sorry, the core dumped is too large so I cannot mail you directly) while compiling Karl's ``TeX for impatients''. It seems a bug in math mode. Please have a check. Thank you! (I generate the plain TeX format like this : \pdfoutput1\input plain\dump, and compile it using ``luatex -fmt=./plain.fmt book) Yue Wang
