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 ?

LuaTeX build error on sparc64/amd64 within TeX Live
by Edd Barrett 12 Oct '08

12 Oct '08

Hello, I am making TeX Live packages for OpenBSD and have hit problems with 64 bit architectures: ---8<---lcoco.c:334:22: ucontext.h: No such file or directory lcoco.c:372: error: syntax error before "ucontext_t" lcoco.c: In function `coco_main': lcoco.c:446: error: structure has no member named `ctx' lcoco.c:446: error: structure has no member named `back' lcoco.c: In function `lua_newcthread': lcoco.c:463: error: structure has no member named `ctx' lcoco.c:463: error: structure has no member named `ctx' lcoco.c:463: error: structure has no member named `ctx' lcoco.c:463: error: structure has no member named `ctx' lcoco.c:463: error: structure has no member named `ctx' lcoco.c: In function `luaCOCO_resume': lcoco.c:479: error: structure has no member named `back' lcoco.c:479: error: structure has no member named `ctx' lcoco.c: In function `luaCOCO_yield': lcoco.c:493: error: structure has no member named `ctx' lcoco.c:493: error: structure has no member named `back' gmake[4]: *** [lcoco.o] Error 1 gmake[4]: Leaving directory `/usr/ports/print/texlive/base/w-texlive_base-2008/t exlive-20080816-source/work/libs/lua51' gmake[3]: *** [posix] Error 2 gmake[3]: Leaving directory `/usr/ports/print/texlive/base/w-texlive_base-2008/t exlive-20080816-source/work/libs/lua51' gmake[2]: *** [../../libs/lua51/liblua.a] Error 2 gmake[2]: Leaving directory `/usr/ports/print/texlive/base/w-texlive_base-2008/t exlive-20080816-source/work/texk/web2c' gmake[1]: *** [all] Error 1 gmake[1]: Leaving directory `/usr/ports/print/texlive/base/w-texlive_base-2008/t exlive-20080816-source/work/texk' gmake: *** [all] Error 1 *** Error code 2 ---8<--- OpenBSD does not use ucontext.h, but interestingly this error does not show on i386. For now I have disabled luatex in the build, due to luatex being in an experimental stage, but I thought it would be good to report this and get on top of it early rather than later. Also I was wondering if it will be possible to build luatex with an external lua (not the one in texlive), but I realise that may not be a question for this list. -- Best Regards Edd http://students.dec.bournemouth.ac.uk/ebarrett

Luatex beta 0.30.0 released
by Taco Hoekwater 30 Sep '08

30 Sep '08

Hi all, I have just uploaded the archives for luatex 0.30.0. This release matches SVN revision #1521. New features: * Readable \tex internal params that are counts, attrs, or dimens are now returned as numbers instead of strings, and skips as node objects. Read-write access to tex's skip registers added: tex.skip[0] etc. * new callback: 'linebreak_callback' to replace the internal paragraph breaking code * the tex table now supports more readable 'convert' values: tex.fontname, tex.pdffontname, tex.pdffontobjnum, tex.pdffontsize, tex.uniformdeviate, tex.number, tex.romannumeral, tex.pdfpageref, tex.pdfxformname (each takes a number as argument) * new readable parameter: tex.fontidentifier(number) returns the \csname associated with that font id * luatex now outputs \FONT<nr> instead of \^^@ in Overfull/Underfull messages if the font's id text is zero (like for expanded fonts) (#77) * luatex --version is split into --version and --credits * There is now (again) an svn revision number in luatex --version (#91) * Add support for more read-only internal access from lua: tex.lastpenalty, tex.lastkern, tex.lastskip, tex.lastnodetype, tex.inputlineno, tex.badness, tex.pdftexversion, tex.pdflastobj, tex.pdflastxform, tex.pdflastximage, tex.pdflastximagepages, tex.pdflastannot, tex.pdflastxpos, tex.pdflastypos, tex.pdfrandomseed, tex.pdflastlink, tex.luatexversion, tex.Alephversion, tex.Omegaversion, tex.Alephminorversion, tex.Omegaminorversion, tex.eTeXminorversion, tex.eTeXversion, tex.currentgrouplevel, tex.currentgrouptype, tex.currentiflevel, tex.currentiftype, tex.currentifbranch, tex.pdflastximagecolordepth (#81) * the old --src-specials are replaced by --synctex (#63) * the \expanded primitive is backported from pdftex 1.50 (#43) * luatex now comes with libpng 1.2.32 * experimental: tex.definefont(string, number) associates a csname string with a font id number Bugs fixed compared to 0.29.0: * dashes were exported wrongly by MPlib * multi-item \discretionaries were broken in various ways (#78, mailinglist) * read_font_info was sometimes called recursively from lua-loaded virtual fonts * do_vf was sometimes called on lua-loaded fonts that where already known to be virtual * trailing junk in tfm files is now ignored (needed for ecrm fonts) * pdf_ignored_dimen was initialized too late, breaking \prevdepth handling and causing output lines to overlap eachother (#72) * pdf.immediateobj() had a printf-related bug * the fontname terminal logging is fixed for strange font file names * lua tex array assignments now listen to the globaldefs setting (tex.count[0] etc) (#92,partial) * \parshape was broken (#70) * there is no longer a ".tex" extension forced on very input file (#74) * eof() for mapfiles was true one byte too soon (#76) * out of range \lefthyphenmin and \righthyphenmin settings now actually disable hyphenation (#90) * tex.unset_attribute() looked too far ahead when a to-be-unset attribute id not only did not exist in the node, but was also higher than the highest set attribute on the node. (#65) * the parameters attr and page_name of read_image() were swapped (this broke \pdfimage with attributes) * tex filenames with spaces in them on the command line are now allowed again (#30) * sometimes pfb fonts were included multiple times without valid reason (#29) * some parts of the pdftex 1.40.9 PNG transparancy hack were still present and caused transparant png handling to fail * \localinterlinepenalty and \localbrokenpenalty were broken * special case catcode tables are now handled better (#23) * the handling of missing .notdef charstrings in old pfb fonts is fixed (#27) 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

BIG news! Thank you, Taco (and friends) ^_^ especially for integrating the synctex support, now I am happy editing with Jonathan's TeXworks editor. btw, what's cooking for 0.40.0? math support or page building?

Problem with complex discretionaries in \hyphenation
by Jonathan Sauer 30 Sep '08

30 Sep '08

Hello, the following PlainTeX file demonstrates my problem: %&luatex \hyphenation{De{k-}{k}{ck}en-licht} \showhyphens{Deckenlicht} % A \hyphenation{Dec-ken-licht} \showhyphens{Deckenlicht} % B \hyphenation{Schne{k-}{k}{ck}en-haus-bau-mei-ster} \showhyphens{Schneckenhausbaumeister} % C \bye This results in: This is LuaTeX, Version snapshot-0.29.1-2008092618 (Web2C 7.5.7) (HyphenationProblem.tex Underfull \hbox (badness 10000) in paragraph at lines 21--21 [][] \tenrm Dek-ke-nlicht Underfull \hbox (badness 10000) in paragraph at lines 25--25 [][] \tenrm Dec-ken-licht Underfull \hbox (badness 10000) in paragraph at lines 30--30 [][] \tenrm Schnek-ke-nhau-sba-ume-ister ) (see the transcript file for additional information) No pages of output. Transcript written on HyphenationProblem.log. B is correct, but A (should be `Dek-ken-licht' instead of `Dek-ke-nlicht' and C (should be `Schnek-ken-haus-bau-mei-ster' instead of `Schnek-ke-nhau-sba-ume-ister') are not: All hyphenation points after the complex discretionary seem to be shifted one character to the left. I'm using the trunk as of friday. What am I doing wrong? Thanks, Jonathan
