Hi, I use artix linux (a fork of arch with systemd alternative init systems). During the texlive package, I get this error: return { ["filename"]="/usr/share/texmf-dist/tex/generic/pgf/basiclayer/pgfcorepoints.code.tex", ["lastcontext"]="\n<inserted text> \n \\inaccessible \n<to be read again> \n \"\n\\pgfmath@catcodes ->\\catcode `\\==12 \\catcode `\\,=12 \\catcode `\\|=12 \\catcode `\\&=12 \\let \"\n \\pgfmath@char@quote \n\\pgfmathparse ->\\begingroup \\pgfmath@catcodes \n \\pgfmath@quickparsefalse \\ifpgfmathfloat \\let \\pgfmath@parse@next =\\pgfmathfloatparsenumber \\else \\let \\pgfmath@parse@next =\\pgfmathparse@ \\fi \\pgfmath@parse@next \n<argument> \\pgfmathparse \n {1cm}\\ifpgfmathmathunitsdeclared \\pgf@x \\pgfmathresult mu\\relax \\else \\pgf@x \\pgfmathresult pt\\relax \\fi \n\\pgfmath@next #1#2->#2\n \n...\nl.926 \\pgfsetxvec{\\pgfpoint{1cm}{0cm}}\n ", ["lastluaerror"]="?", ["lasttexerror"]="!

Stack overflow when using Neo Euler for math

Hi, I'm in the process of updating to TeXlive 2023 after a long time of light use with 2018.

meta-imp-fen in mkxl?
by Thomas A. Schmitz 31 Mar '23

31 Mar '23

Hi all, I wanted to use a rightbrace as background for a table, as defined in meta-imp-fen.mkiv. Unfortunately, I can't get it to work, for 2 reasons: 1. meta-imp-fen doesn't appear to be ported to mkxl. 2. When I try to compile with the --luatex switch, I get this error message: tex error > tex error on line 101 in file /mnt/shared/lmtx/tex/texmf-context/tex/context/base/mkiv/meta-imp-dum.mkiv: ! Undefined control sequence l.101 \newinteger \c_grph_replacement_n So, I'm a bit stymied right now. What can be done? All best Thomas

Numbering of figures after defining a new float
by Willi Egger 31 Mar '23

31 Mar '23

Hello everybody, I am still working on the previously mentioned project, consisting out of different parts. There are about 25 chapters in each part and most of the chapters contain figures. When using the predefined figure environment, then all figures in the figure-list are placed correctly though at each part the numbering restarts. Now I tried to implement for each part its own float environment, which enables me to produce a figure-list per part with subtitels. How ever in the newly defined floats there is no continuous numbering i.e. chapternumber.serialnumber. Instead each float get the chapter number only. How to get the numbering right? Kind regards Willi The following example shows what happens: \useMPlibrary[dum] \definefloat[Afigure][Afigures][figures] \definefloat[Bfigure][Bfigures][figures] \setuphead [part] [placehead=yes, page=yes] \setuphead [chapter] [page=no] \starttext \starttitle[title=List of figures] \startsubject[title=Figures (predefined figureenvironment)] \placelistoffigures \stopsubject \startsubject[title=Figures A] \placelistofAfigures \stopsubject \startsubject[title=Figures B] \placelistofBfigures \stopsubject \stoptitle \startpart[title=Part ONE] \startchapter[title={Chapter one in part one}] %les21 \startplaceAfigure [location=left, reference=fig:dumA, title={Dummy A}] {\externalfigure[dummy][width=0.6\textwidth]} \stopplaceAfigure \startplacefigure [location=left, reference=fig:dumB, title={Dummy B}] {\externalfigure[dummy][width=0.6\textwidth]} \stopplacefigure \startsection[title=Section A] \startplaceAfigure [location=left, reference=fig:dumC, title={Dummy C}] {\externalfigure[dummy][width=0.6\textwidth]} \stopplaceAfigure \stopsection \stopchapter \stoppart \startpart[title=Part TWO] \startchapter[title=Chapter one in part two] \startplaceBfigure [location=left, reference=fig:dumD, title={Dummy D}] {\externalfigure[dummy][width=0.6\textwidth]} \stopplaceBfigure \stopchapter \stoppart \stoptext

characters.tex.toutf bug
by Max Chernoff 30 Mar '23

30 Mar '23

Hi Hans, "characters.tex.toutf" only works if there is a backslash somewhere in its input string. This leads to some really surprising behaviour in the following example: \definefontfeature[default][tlig=no, trep=no] \startbuffer[test-bib] @article{one, author = {``Author---\v{O}ne''}, } @article{two, author = {``Author---Two''}, } \stopbuffer \usebtxdataset[test-bib.buffer] \starttext \placelistofpublications[method=dataset] \stoptext Removing the following lines elseif not find(str,"\\",1,true) then return str from the definition of "characters.tex.toutf" in "char-tex.{lmt,lua}" fixes this issue for me. Thanks, -- Max

contextgarden wiki
by Jim 30 Mar '23

30 Mar '23

At https://wiki.contextgarden.net/Wiki:About there is a Contact section, including For general questions (any questions!), start a new topic on the Context_wiki:Discussions page. If you need the help of an administrator, there is a list of administrators at Context_wiki:Administrators. There are *no* topics on the Discussions page, and the Administrators page doesn't exist. This causes me to be concerned that no one is there. Is anyone there? In case anyone wonders why I am asking... I was looking at the wiki page for "\listing", which is no longer in Mk IV (and may also not be in Mk II (I didn't check)). In 2015 both Hans and Wolfgang mentioned in this list that the command was gone. I just edited the wiki to note that the command was gone, should anyone venture there, but I think even better would be to delete the wiki page entirely. However, that sounds like a decision for senior management, and I was going to ask them, but I couldn't find the right corner office. Thoughts? Jim

Spacing problem around decimal point
by Gavin 29 Mar '23

29 Mar '23

Hi List, I’m getting strange spaces around some decimal points after a clean LMTX install. MWE: \starttext \startformula v = \frac{1.32}{1.41} = 0.935 \stopformula \stoptext This produces the result attached below. The 1.32 looks fine, but the next two numbers have excess space around the decimal point. Adding the line \showmakeup[mathglue] %\mathspacingmode=1 to the preamble reveals that the second and third decimal points are being treated as binary operators. It’s very strang. Are others getting this? Gavin

Text editors
by Alexandre Christe 28 Mar '23

28 Mar '23

Dear ConTeXt users, I'm wondering what kind of typesetting system / syntax highlighting / completion you're using. I've been using myself the simple_Context package for SublimeText which I scavenged a while ago before it was made unavailable (I wanted to attach but it's too big for the list). But it's sort of a dead-end. Open to anything from vim/neovim to emacs or more exotic. Maybe it would be nice to show the config. (And yes I've seen the Wiki page https://wiki.contextgarden.net/Text_Editors but I've the feeling some content is outdated.) Thanks in advance, Alex

xtable - what might prevent splitting?
by jbf 28 Mar '23

28 Mar '23

I cannot understand why my xtable setup does not split to the next page. As far as I can see I have it set up correctly... though obviously not! What might be wrong? Below is a sample. In the real case the number of rows would demand a second page. \setupxtable[width=4cm,option={stretch,width}] \setupxtable[split=yes] \starttext \placetable[here]{} \startxtable \startxrow \startxcell cell one \stopxcell \startxcell cell two \stopxcell \startxcell cell three\stopxcell \stopxrow ... and so on and so forth for twenty or so rows, but certainly enough to require a second page \stopxtable \stoptext Julian
