Fwd: Re: [tlbuild] TL25 rebuild please

Hi Hans, Someone posted on the tlbuild mailing list that LuaMetaTeX segfaults whenever making the ConTeXt format on OpenBSD. I'm all out of ideas for how to fix this, so hopefully you have some suggestions? The original thread started at https://tug.org/pipermail/tlbuild/2025q1/005651.html Thanks, -- Max -------- Forwarded Message -------- From: Robert Alessi <alessi(a)robertalessi.net> To: Max Chernoff <tex(a)maxchernoff.ca> Cc: tlbuild(a)tug.org Subject: Re: [tlbuild] TL25 rebuild please Date: 2025-03-06 12:15:08 AM > Hi Max, > > On Wed, Mar 05, 2025 at 01:00:57AM -0700, Max Chernoff wrote: > > folder, you can build a debug version with: > > > > $ export CFLAGS='-ggdb3 -O0' CXXFLAGS='-ggdb3 -O0' LDFLAGS='-ggdb3' > > $ sed -i '/-O3/d' CMakeLists.txt > > $ sed -i 's/"-s"/""/' CMakeLists.txt > > $ sed -i '/STRIP/d' cmake/luametatex.cmake > > $ mkdir debug/ && cd debug/ > > $ cmake -DCMAKE_BUILD_TYPE=Debug -DLMT_PERMIT_LUA_LIBRARIES=yes .. > > At this point I got this CMake warning: > > CMake Warning: > Manually-specified variables were not used by the project: > > LMT_PERMIT_LUA_LIBRARIES > > > $ cmake --build . --parallel 16 > > Then the build process succeeded. > > > > > The command to manually build a format is > > > > $ luametatex --ini --lua=$(kpsewhich luat-cod.lmt) $(kpsewhich cont-en.mkxl) > > > > Since you compiled with clang, I guess you'll probably use lldb, but > > with GDB and an intentionally-broken binary, this is what I get: > > > > $ gdb --args luametatex --ini --lua=$(kpsewhich luat-cod.lmt) $(kpsewhich cont-en.mkxl) > > Then I copied luametatex to my TL bin dir and I ran: > > $ lldb --arch x86_64 -- luametatex --ini --lua=$(kpsewhich luat-cod.lmt) $(kpsewhich cont-en.mkxl) > > Here is what I got: > > (lldb) target create --arch=x86_64 "luametatex" > Current executable set to '/usr/local/texlive/2025/bin/custom/luametatex' (x86_64). > (lldb) settings set -- target.run-args "--ini" "--lua=/usr/local/texlive/2025/texmf-dist/tex/context/base/mkxl/luat-cod.lmt" "/usr/local/texlive/2025/texmf-dist/tex/context/base/mkxl/cont-en.mkxl" > (lldb) r > Process 28175 launched: '/usr/local/texlive/2025/bin/custom/luametatex' (x86_64) > This is LuaMetaTeX, Version 2.11.07 initex > (/usr/local/texlive/2025/texmf-dist/tex/context/base/mkxl/cont-en.mkxl(context.mkxl(syst-ini.mkxl)(norm-ctx.mkxl)(syst-pln.mkxl)(luat-cod.mkxl<+ /usr/local/texlive/2025/texmf-dist/tex/context/base/mkxl > [...] > open source > level 1, order 35, name 'core-ini.mkxl' > loading > ConTeXt Core Macros / Additional Initialization > close source > level 1, order 35, name 'core-ini.mkxl' > open source > level 1, order 36, name 'core-env.mkxl' > loading > ConTeXt Core Macros / Environments > Process 28175 stopped > * thread #1, stop reason = signal SIGSEGV > frame #0: 0x000009667aa8c9d8 luametatex`texlib_aux_checked_register [inlined] texlib_aux_valid_register_index(L=0x000009691de9f708, slot=1, cmd=<unavailable>, base=<unavailable>, max=65535, constant_cmd=<unavailable>) at lmttexlib.c:1277:74 > 1274 } > 1275 if (index >= 0 && index <= max) { > 1276 return index; > -> 1277 } else if (index < (eqtb_size + lmt_hash_state.hash_data.ptr + 1) && eq_type(index) == constant_cmd) { > ^ > 1278 return index; > 1279 } else { > 1280 return -1; > (lldb) q > Quitting LLDB will kill one or more processes.

How to stop column text from crashing into content afterwards?
by Joel 06 Mar '25

06 Mar '25

It took a lot of trial and error, but here's the glitch I am seeing in this minimum working example: \starttext \startcolumns[n=2] \section{Title} \input knuth \section{Title} \input knuth \section{Title} \input knuth \section{Title} \startitemize \dostepwiserecurse{1}{11}{1}{ \vbox{ \startitem Question \recurselevel \startitemize \startitem A\stopitem \startitem B\stopitem \startitem C\stopitem \startitem D\stopitem \stopitemize \stopitem } } \stopitemize \stopcolumns \section{Title} \input knuth \startcolumns[n=2] \section{Title} \input knuth \section{Title} \input knuth \section{Title} \input knuth \section{Title} \startitemize \dostepwiserecurse{1}{11}{1}{ \vbox{ \startitem Question \recurselevel \startitemize \startitem A\stopitem \startitem B\stopitem \startitem C\stopitem \startitem D\stopitem \stopitemize \stopitem } } \stopitemize \stopcolumns \section{Title} \input knuth \section{Title} \input knuth \section{Title} \input knuth \stoptext If you render it and go to page 7, you will see that the item in Question 11, choices C and D are covering up "10 Title" on the same page. In my own document, this is happening a great deal. I could use a page break, but as you see here with question 11, that would leave a huge piece of the page gone. I've even seen some cases where it seems the columns start writing over each other, instead of going to the next page. So image in this documetn if question 8, 9, and 10 appeared on topo of 5, 6, and 7. Is there any way to present this terrible behavior from rendering like this? --Joel

LMTX/LuaTeX: much bigger output size in imposition
by Pablo Rodriguez 05 Mar '25

05 Mar '25

Dear list, I create booklets with the following source: \setuppapersize[A5, landscape][A4] \setuparranging[2UP] \setuplayout[page] \setuppagenumbering[alternative=doublesided] \setupinteractionscreen[option={landscape,paper}] \starttext \def\Doc{xml-mkiv.pdf} \getfiguredimensions[\Doc] \dorecurse{\noffigurepages} {\externalfigure[\Doc][page=\recurselevel, width=\textwidth]} \stoptext In this case, I need to impose the resulting PDF file again: \setuppapersize[A5, landscape][A4] \setuparranging[2TOP] \setuplayout[page] \setuppagenumbering[alternative=doublesided] \setupinteractionscreen[option={portrait,paper}] \starttext \def\Doc{booklet.pdf} \getfiguredimensions[\Doc] \dorecurse{\noffigurepages} {\externalfigure[\Doc][page=\recurselevel, width=\textwidth] \externalfigure[\Doc][page=\recurselevel, width=\textwidth]} \stoptext Generating this second booklet (from the same PDF document), LMTX generates a resulting PDF document which is four times bigger than the one generated by LuaTeX. In fact, these are the file sizes: 1.2M Mar 4 18:38 xmlpdf-lmtx.pdf 321K Mar 4 18:41 xmlpdf-luatex.pdf It seems as LMTX was (almost) disabling PDF compression on the second imposition. Would anyone be so kind to confirm this issue? Many thanks for your help, Pablo

Planned server maintenance Wednesday 5 March
by Taco Hoekwater 05 Mar '25

05 Mar '25

Hi all, Today, Wednesday 5 March we will be upgrading the operating system software of the NTG/ConTeXt Group web server. Starting at 1pm local time services like this and other ntg.nl and contextgarden.net mailing lists, the ConTeXt wiki, and the NTG and ConTeXt Group websites will be offline for a (hopefully short) period. Komende woensdag 5 maart gaan we de besturingssysteem software van de NTG/ConTeXt Group webserver upgraden. Vanaf 13:00 uur lokale tijd zijn diensten als deze en andere ntg.nl en contextgarden.net mailinglijsten, de ConTeXt wiki en de NTG en ConTeXt Group websites voor een (hopelijk korte) periode offline. Best wishes, Taco

help with \writetolist alignment
by jbf 05 Mar '25

05 Mar '25

I need a little help to get alignment of a \writebetweenlist correct. I currently have the following in the frontmatter (after the \placecombinedlist etc.) \startfrontmatter ... \starttitle[title={Introduction}] Blah blah blah \stoptitle \writebetweenlist[title]{Essays} \stopfrontmatter The Title header is almost flushleft with the margin, so I expected 'Essays' to do the same. Instead it lines up with all the Chapters in bodymatter which are indented somewhat (.5cm instead of .1cm for Title). In other words, I end up with: Introduction Essays How can I get 'Essays' to line up beneath Introduction? I thought because I am calling it a Title head it should follow what I have for title, viz., \setuplist[title][label=no,distance=.1cm,alternative=b,before=] Julian

Strange display of math when enabling export xml/html/xhtml
by Christoph Hintermüller 05 Mar '25

05 Mar '25

Dear Hans, Dear all Once angain me trying to convert my lecture notes into epub. At first: finally switching after some installation hassle to really latests context disttibution -------------------------------------------------------------------- mtx-context | Cmtx-context | ConTeXt Process Management 1.06mtx-context | mtx-context | main context file: /usr/local/share/context/tex/texmf- context/tex/context/base/mkiv/context.mkiv mtx-context | current version: 2025.02.28 18:16 mtx-context | main context file: /usr/local/share/context/tex/texmf- context/tex/context/base/mkxl/context.mkxl mtx-context | current version: 2025.02.28 18:16 onTeXt Process Management 1.06 mtx-context | mtx-context | main context file: /usr/local/share/context/tex/texmf-context/tex/context/base/mkiv/context.mkiv mtx-context | current version: 2025.02.28 18:16 mtx-context | main context file: /usr/local/share/context/tex/texmf-context/tex/context/base/mkxl/context.mkxl mtx-context | current version: 2025.02.28 18:16 -------------------------------------------------------------------- solved all my previous problems. But what i now notices is a strange behaviour regarding the math equations in the resulting html, xml and xhtml when there is at least one figure with an external graphic in the document (see attached hopefully minimal enough example). The xml/html/xhtml files contain a mathcontent tag/div which correctly contains the mathml for the equation. the tag/div it selve has the image attibute set which points to the first image file imported before. I do guess this is intended to be a fallback, in case browser or read can not properly handle and display mathml content. I do further guess that in my installation i do miss some external program or library or some environment variable is not set or not properly set. In parallel i have installed texlive - without outdated luatex context- as i do need latex for other stuff too. So my question is where and how to tweak installation to get a proper result. Best whishes Christoph

how to reset and switch fallbackfont?
by autumnus 03 Mar '25

03 Mar '25

hi, As described in the title, how to reset fallbackfont? I have created a number of Chinese typescripts and related fallbackfont (latin). However, in the actual operation process, I found that if you want to switch different fallbackfont, you must change the bodyfont at the same time (\setupbodyfont). The following is an example. How should I reset and switch to fallbackfont without changing the bodyfont? %%%%%%% \definefontfeature[zh][mode=node,script=hang,lang=zhs] \startsetups fallbacks:reset \resetfontfallback[serifwhatever] \resetfontfallback[serifboldwhatever] \resetfontfallback[serifitalicwhatever] \resetfontfallback[serifbolditalicwhatever] \stopsetups \startsetups fallback:lm \definefontfallback[serifwhatever] [lmroman10-regular] [0x0000-0x0400][force=yes] \definefontfallback[serifboldwhatever] [lmroman10-bold] [0x0000-0x0400][force=yes] \definefontfallback[serifitalicwhatever] [lmroman10-italic] [0x0000-0x0400][force=yes] \definefontfallback[serifbolditalicwhatever][lmroman10-bolditalic][0x0000-0x0400][force=yes] \stopsetups \startsetups fallback:eb \definefontfallback[serifwhatever] [ebgaramondregular] [0x0000-0x0400][force=yes] \definefontfallback[serifboldwhatever] [ebgaramondbold] [0x0000-0x0400][force=yes] \definefontfallback[serifitalicwhatever] [ebgaramonditalic] [0x0000-0x0400][force=yes] \definefontfallback[serifbolditalicwhatever][ebgaramondbolditalic][0x0000-0x0400][force=yes] \stopsetups \starttypescript [serif] [zhfont] \definefontsynonym [Serif] [AdobeSongStd-Light] [features=zh,fallbacks=serifwhatever] \definefontsynonym [SerifBold] [AdobeHeitiStd-Regular][features=zh,fallbacks=serifboldwhatever] \definefontsynonym [SerifItalic] [AdobeKaitiStd-Regular][features=zh,fallbacks=serifitalicwhatever] \definefontsynonym [SerifBoldItalic][AdobeHeitiStd-Regular][features=zh,fallbacks=serifbolditalicwhatever] \stoptypescript \starttypescript[myfont] \definetypeface[myfont][rm][serif][zhfont] \stoptypescript \usetypescript[myfont] \starttext \setups{fallback:lm} \setupbodyfont[myfont,rm,12pt] fonts {\bf fonts} {\bi fonts} {\it fonts} % will be lm font \\\the\font \setups{fallbacks:reset} \setups{fallback:eb} fonts {\bf fonts} {\bi fonts} {\it fonts} % expected eb but lm \\\the\font \setups{fallbacks:reset} \setups{fallback:eb} \setupbodyfont[myfont,rm,12pt]%% any other chinese font, and change to eb fonts {\bf fonts} {\bi fonts} {\it fonts} \\\the\font \stoptext %%%% best wishes, autumnus

New example, Distance between the background and the frame not wanted
by Ursula Hermann 03 Mar '25

03 Mar '25

Dear List, I have a little new example. What I do like to know: what command do I use, if I do not want a distance between the blackrule and the frame? I know, it is a problem with the distance, but I do not know the right command. \setuppapersize[A4] \blackrule[color=darkmagenta, height=3.ex, width=13.50cm]\par \defineframed [Me] [background=color,backgroundcolor=darkmagenta] \Me[frame=on, corner=rectangular, topframe=off, bottomframe=off, framecolor=blue]{Hello} \stoptext Many thanks Uschi

month form \currentdate in Roman numerals
by Pablo Rodriguez 03 Mar '25

03 Mar '25

Dear list, I would like to get the current month in Roman numerals (just now, it would be XII for December). The best I get is: \currentdate[\cldcontext{converters['R'] (tonumber(os.date("\letterpercent m", os.date(os.time()))))}] This strikes me as too complex (even for someone who cannot code). Is there now simpler way to write that? Just in case it may be relevant, this is part of the full day reference. Many thanks for your help, Pablo
