Problems with --lua-switch
by Ulrike Fischer 16 Oct '08

16 Oct '08

Hello, I have writen a small init.lua-file which sets the package.path so that the lua-scripts can be found. I'm calling this init.lua with luatex --lua=init.lua --fmt=pdfluatex <file> That works fine but has the side effect that memory settings like e.g. param_size are no longer taken from the texmf.cnf but are reset to their default (in this case to 60). Is this expected? Do I have to set the texconfig-table if I load such a init-file? -- Mit freundlichen Grüßen Ulrike Fischer mailto:list@nililand.de

Bug in \latelua?
by Oliver Heins 15 Oct '08

15 Oct '08

Hi, while playing around with luatex and ledmac I produced somewhat strange PDF's. This is a minimal example: \pdfcompresslevel=0 \documentclass{article} \usepackage[T1]{fontenc} \usepackage{ledmac} \usepackage{MinionPro} \makeatletter \renewcommand*{\do@line}{% {\vbadness=10000 \splittopskip=0pt \do@linehook \l@demptyd@ta \global\setbox\one@line=\vsplit\raw@text to\baselineskip}% \unvbox\one@line \global\setbox\one@line=\lastbox \getline@num \affixline@num \hb@xt@ \linewidth{% \l@dld@ta\add@inserts\affixside@note \l@dlsn@te% left side note {\ledllfill \hb@xt@ \wd\one@line{\new@line\unhbox\one@line}% \ledrlfill\l@drd@ta% \l@drsn@te}% right side note \latelua0{}% <-- This is the new line }% \add@penalties} \makeatother \begin{document} \beginnumbering \pstart \input tufte \pend \endnumbering \end{document} I'm using the commercial Minion Pro font here, because it visualizes the faults of the pdf: The last charakter of each line is overprinted by a crossed rectangle. In case you don't have Minion Pro on your computer, I put the pdf on the web: http://sopos.org/olli/examples/lualedmac.pdf (and http://sopos.org/olli/examples/lualedmac2.pdf for a version done without the \latelua statement). Using lmodern the PDF turns out to be still faulty, though one can't see on screen. I investigated a little bit and took a look into the pdf. The pdf contains extra newlines, which appear *within* the last string of a line (so, if a line ends with »ca-«, the pdf file looks like this: ...-241(c)-3(a- )]TJ...) Here's the beginning of such a pdf file: %PDF-1.4 %ÐÔÅØ 3 0 obj << /Length 2672 >> stream BT /F19 9.9626 Tf 148.712 707.125 Td [(W)96(e)-241(t)-6(hr)-6(i)6(v)8(e)-242(in)-242(inf)8(o)12(r)-5(m)2(a)19(t)-4(io)11(n||t)-5(hic)5(k)-242(w)7(o)12(r)4(ld)3(s)-241(b)-9(e)-5(c)-3(a)18(u)3(s)-7(e)-242(o)11(f)-242(o)10(ur)-241(m)2(a)9(r)-28(v)7(e)4(lo)11(u)3(s)-241(a)8(n)4(d)-242(e)-8(v)7(er)-28(y)7(d)-2(a)17(y)-241(c)-3(a- )]TJ -14.944 -11.955 Td [(p)-5(aci)11(t)-2(y)-337(t)5(o)-336(s)-8(e)3(le)-4(c)-7(t,)-365(e)-5(di)11(t,)-363(sin)7(g)-6(le)-337(o)10(u)12(t,)-364(s)4(t)-4(r)-10(uc)-7(t)9(ur)13(e)6(,)-363(hig)-7(h)-5(lig)-7(h)18(t,)-364(g)-5(r)12(o)11(u)12(p)29(,)-363(p)-5(a)8(ir)63(,)-364(m)3(er)8(g)8(e)6(,)-363(h)2(a)9(r)-5(m)3(o)12(nize)6(, )]TJ 0 -11.955 Td [(sy)-3(n)18(t)-5(h)3(esize)6(,)-328(f)8(o)-8(c)-7(u)2(s,)-327(o)11(r)8(ga)9(nize)6(,)-328(co)11(n)4(den)8(s)-7(e)5(,)-327(r)12(e)-4(d)11(uce)6(,)-327(b)-10(o)11(i)-4(l)-308(do)15(w)-2(n,)-328(c)5(h)4(o)-8(os)-8(e)5(,)-328(c)-3(a)18(t)6(eg)8(o)12(r)-5(ize)5(,)-327(c)-3(a)18(t)-5(a)-5(log)-32(, )]TJ 0 -11.955 Td [(c)5(l)-2(a)2(s)5(sif)-16(y)72(,)-238(li)2(s)5(t,)-238(a)7(bs)5(t)-4(rac)-7(t,)-238(s)-8(c)-3(a)8(n,)-238(lo)-9(o)6(k)-235(in)18(t)6(o)29(,)-238(ide)-6(a)-5(lize)5(,)-238(i)2(s)-7(o)6(l)-2(a)18(t)6(e)6(,)-238(di)2(s)-7(cr)-6(imin)2(a)19(t)6(e)6(,)-237(di)2(s)5(t)-4(in)7(gui)3(s)4(h,)-238(s)-8(cr)12(e)-4(en, )]TJ/F19 6.9738 Tf -14.905 -11.956 Td [(\242)]TJ/F19 9.9626 Tf 14.905 0 Td [(p)11(ig)8(e)-4(o)11(n)-4(h)3(o)7(le)6(,)-270(p)11(ic)6(k)-261(o)15(v)8(er)63(,)-270(s)-8(o)11(r)-9(t,)-271(in)18(t)6(eg)-4(ra)18(t)6(e)6(,)-269(b)6(len)4(d)6(,)-270(in)7(s)5(p)-8(e)-5(c)-7(t,)-271(\235)-5(l)11(t)6(er)63(,)-270(l)11(um)19(p)29(,)-270(s)3(k)-3(i)11(p)29(,)-269(sm)3(o)-8(o)10(t)-5(h,)-271(c)5(h)19(un)-4(k, )]TJ 0 -11.955 Td [(a)17(v)8(era)5(g)8(e)6(,)-279(a)18(p)11(p)12(r)13(o)16(xim)3(a)19(t)6(e)6(,)-279(c)5(l)12(u)3(s)5(t)6(er)63(,)-279(a)4(g)-5(g)-5(r)12(ega)19(t)6(e)6(,)-278(o)10(u)12(t)-5(lin)3(e)6(,)-279(s)4(umm)3(a)9(r)-5(ize)5(,)-279(i)11(t)6(emize)6(,)-279(r)12(e)-7(v)-3(ie)-8(w)72(,)-279(di)11(p)-268(in)18(t)6(o)29(, )]TJ 0 -11.955 Td [(\236i)11(p)-277(t)-6(hr)12(o)11(ug)-6(h,)-291(b)11(r)13(o)16(ws)-7(e)4(,)-290(g)-7(l)-3(a)8(n)4(ce)-277(in)18(t)6(o)29(,)-290(le)-6(a)8(f)-277(t)-6(hr)12(o)11(ug)-6(h,)-292(s)3(k)-3(im,)-291(r)12(e\235n)4(e)6(,)-290(en)18(um)4(era)19(t)6(e)6(,)-290(g)-7(le)-6(a)8(n,)-290(sy)-3(n)3(o)11(p- )]TJ 0 -11.955 Td [(size)5(,)-226(w)-3(inn)3(o)16(w)-226(t)-6(h)3(e)-226(w)-7(h)3(e)-5(a)18(t)-226(f)-10(r)12(o)12(m)-226(t)-6(h)3(e)-226(c)5(h)3(a)9(\232)-226(a)8(n)4(d)-226(s)-8(ep)-5(a)8(ra)19(t)6(e)-226(t)-6(h)3(e)-226(s)3(h)4(e)-4(ep)-227(f)-10(r)12(o)12(m)-226(t)-6(h)3(e)-226(g)7(o)-4(a)18(ts. )]TJ 170.162 -484.184 Td [(\325)]TJ ET endstream endobj Looking in luatex.web, I found that the definition of \latelua contains a line »pdf_print_nl«.

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
