Warning: "nodes: unable to store reference from lua in tex"
by Lukas/ConTeXt 26 Feb '21

26 Feb '21

Hello, after I renewed ConTeXt MkIV, I started to get the following warning: " ... luatex warning > nodes: unable to store reference from lua in tex ... (repeated more times) " This happens when I try to typeset a looo...ong table (by \start/\stop-tabulate) over several pages. It used to work OK with a Ctx version several months (or half year) ago. Is there a simple way to overtake the problem? MWE: ---- \starttext \startluacode context[[ \starttabulate[|Tr|] \HL \NC AABBCC \NC\AR \HL[3] ]] for i = 1, 4000 do context.NC(i) context.NC() context.AR() end context[[ \HL \stoptabulate ]] \stopluacode \stoptext ---- Best regards, Lukas

Help figuring why long document stops short in xml export
by Christoph Hintermüller 24 Feb '21

24 Feb '21

Hi What command line parameters, trackers etc I should activate when i want to figure why my document lacks content worth of several pages in xml export while the pdf which is created in parallel contains all pages. I'm using mtx-context | ConTeXt Process Management 1.04 mtx-context | mtx-context | main context file: <prefixpath>/tex/texmf- context/tex/context/base/mkiv/context.mkiv mtx-context | current version: 2021.02.14 16:39 mtx-context | main context file: <prefixpath>/tex/texmf- context/tex/context/base/mkxl/context.mkxl mtx-context | current version: 2021.02.14 16:39 Would switching to lmtx may be helpful in at least figuring why or be the only known solution? The Document it self is my lecture notes which are about 125 Pages long. The xml export ends at Page 63. Are there any known commands which can cause exporter to give up early and thus should in export be avoided or be put in mode dependent block hiding them form exporter. Any hint what i should, would have to check and how to hopefully grabe any hint where to amend the document to get full output. Currently i have not made images mode dependent (pdf:metapost, xml:png/svg). Could that be a reason why exporter finally ends document early? I'm sorry to be so clue less to not be able to provide more information. The document it self is too big to be posted and i do not want to make it public anyway, but if required i can provide a share link. Best Christoph Hintermüller

Letter module not found by LMTX
by Henning Hraban Ramm 24 Feb '21

24 Feb '21

Hi, I just stumbled upon this, no time for further checks ATM: \usemodule[letter] can’t find the installed letter/correspondence module in LMTX mode, while MkIV works flawlessly. Don’t know if other modules are affected. Hraban

Possible problem with context using the ARM 64bit download for Apple Silicon M1
by Keith McKay 23 Feb '21

23 Feb '21

Hi all I have been using ConTeXt (X86 64bits) on my mac mini Apple Silicon M1 and it works well using Rosetta translation for the M1. I recently installed the ARM 64bits version (separately from the X86 64bits version) which I assume does not require translation using Rosetta. However I had a error with the lmt_shade command in the ARM 64bits ConTeXt verson but not in with the X86 64bits version of ConTeXt. The MWE is shown below. This is actually taken from the LuaMetaFun manual. I also noticed that some figures are missing in the manual (Chapter 7, Shade) which is part of the ARM 64bit tree but not in the manual in the X86 64bits tree.

Arbitrary equation tags... again
by Jairo A. del Rio 23 Feb '21

23 Feb '21

Hi. list. Is it possible to assign an arbitrary equation tag in ConTeXt? I've seen solutions here; https://tex.stackexchange.com/questions/400257/tag-equation-in-context-with… but none of them works as expected (either the formula counter is still incrementing with arbitrary conversions or cross-references don't work). I imagine some things have changed in 2021 and I hope a better solution is feasible nowadays. Best regards, Jairo

[LMTX] fonts problem (again)
by kaddour kardio 23 Feb '21

23 Feb '21

Hi! Once again i'm unable to load my system's font which is working well with MKIV. i have followed the steps : export OSFONTDIR=~/.local/share/fonts:/usr/share/fonts:/usr/share/texmf/fonts/opentype/ mtxrun --generate mtx run --make mtxrun --script fonts --reload without success. This problem occurred to me since december 2020, i update LMTX weekly from the archlinux user repo (aur) binary. Any suggestions? -- Dr YAHYAOUI Mohamed Kaddour, cardiologue .

lmtx error: You can't use 'integer 340' in internal vertical mode
by juh 23 Feb '21

23 Feb '21

Hi, I can't yet provide a mwe as the project is quite complex and includes color profiles and bleed. I can process it with context. When I process it using lmtx but without colorprofiles and bleed, it works. When I process it using lmtx with colorprofiles and bleed, it get this error: tex error > tex error on line 1 in file ./prod-poster-motiv-souveraenitaet.tex: You can't use 'integer 340' in internal vertical mode <macro> \page_shipouts_arrange ...setbox \shipoutscratchbox \hpack {\getobject \??arrangedpage {\the \realpageno }}\fi \pusharrangedpage \shipoutscratchbox \deadcycles \zerocount \endgroup <macro> \page_boxes_shipout ...tbox \shipoutscratchbox \hpack {#1}\page_shipouts_handle {\finalizeshipoutbox \shipoutscratchbox \box \shipoutscratchbox } \fi \setnextrealpageno \the \everyaftershipout \ifcase \c_page_boxes_flush_n \else \page_boxes_flush_after \fi <macro> \page_otr_construct_and_shipout #1#2#3->\forgetall \page_boxes_shipout {\page_boxes_constructed_page #1#2} \page_otr_flush_pending_content \page_otr_check_for_pending_inserts \inpagebodytrue \pagebodymode \plusone \page_otr_command_flush_saved_floats \page_otr_command_set_vsize \str <macro> \currentcolorname \page_otr_command_side_float_output \ifconditional \c_page_sides_short \global \setfalse \c_page_sides_short \else \global \d_page_sides_vsize \d_page_sides_vsize_reset \global \c_page_sides_n_of_lines \zerocount \fi <macro> \currentcolorname \ifcsname \??otrtriggers \the \outputpenalty \endcsname \lastnamedcs \else \page_otr_command_routine \fi <output> {\inotrtrue \the \everybeforeoutput \page_otr_triggered_output_routine \relax \the \everyafteroutput } ... <line 3.47> \stopproduct Are there changes with modes or setupbackend in lmtx?
