Luatex beta 0.30.1 released
by Taco Hoekwater 14 Oct '08

14 Oct '08

Hi all, I have just uploaded the archives for luatex 0.30.1. This release matches SVN revision #1552. There are no new features, just bugfixes and speedups: * Invalid return values from the linebreak_filter callback are now handled gracefully (was crashing) * a preinstalled ctangle is no longer needed except when cross-compiling * In 0.30.0, the .notdef fix was incorrectly applied to truetype / opentype fonts. * A bunch of all memory leaks is fixed * In lua, f:read('*a') now uses signicantly less memory * The number of \catcodetables is now limited to 64KB (for speed reasons) * Luatex could crash if there were PDF images with and without page /Group included on the same page * Lua coco now always uses setjmp (for OpenBSD compatibility) * The embedded mplib is updated to the latest svn version * # marks (characters with catcode 6) are no longer doubled inside \directlua * Handling the nul character (U+0000) with catcode 13 (active) was broken * Luatex could crash on win32 with an access violation because there was one predefined language too few (the one matching \language=-1) 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

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

Problem with a test with ^^-notation.
by Ulrike Fischer 08 Oct '08

08 Oct '08

Hello, I ran into a problem with the LaTeX-package listing related to the handling of extendedchars (it can be easily avoid by using extendedchars=false). I think I have tracked down the problem to the following difference between luatex and pdftex/xetex: \documentclass{article} \begin{document} \catcode`\^^00=13 \ifnum`^^00=0 ja \else nein \fi \end{document} When processed with LaTeX or XeLaTeX I get a document with "ja". Luatex gives "nein". Is this difference to be expected? -- Mit freundlichen Grüßen Ulrike Fischer mailto:list@nililand.de

# => ## in \directlua
by Jonathan Sauer 08 Oct '08

08 Oct '08

Hello, take the following PlainTeX file: %&luatex \def\recatcode#1{% \directlua0{% tex.sprint('\luaescapestring{\unexpanded{#1}}')% texio.write_nl('\luaescapestring{\unexpanded{#1}}')% }% } \recatcode{% \def\test#1{`#1'}% } \bye This results in This is LuaTeX, Version snapshot-0.30.0-2008093018 (Web2C 7.5.7) (MacroParameterCharacter.tex \def \test ##1{`##1'} ! Parameters must be numbered consecutively. <to be read again> ## l.1 \def \test ## 1{`##1'} \recatcode ...uaescapestring {\unexpanded {#1}}')} l.12 } ? x TeX interrupted. No pages of output. Transcript written on MacroParameterCharacter.log. So `#' is transformed into `##' when passed from TeX to Lua. Is this a bug or a feature? Jonathan
