Repeating binary operators with split multiline formulas
by Adam Reviczky 21 Aug '22

21 Aug '22

Hi, Since there has been a lot of work done on the math side of things, I wanted to ask if there is an automated way to have binary operators repeated when splitting a formula. From the MKIV math manual there is an option to move the operators into the new line: \setupmathematics[setups=math:spacing:split] \setupformulas[split=yes,align=flushleft] \startformula x\dorecurse{30}{ + #1x^{#1x}} = 10 \stopformula Would it be possible to achieve this via a custom setup like math:spacing:split to get an output like this? 𝑥 + 1𝑥1𝑥 + 2𝑥2𝑥 + 3𝑥3𝑥 + 4𝑥4𝑥 + 5𝑥5𝑥 + 6𝑥6𝑥 + 7𝑥7𝑥 + 8𝑥8𝑥 + 9𝑥9𝑥 + 10𝑥10𝑥 + + 11𝑥11𝑥 + 12𝑥12𝑥 + 13𝑥13𝑥 + 14𝑥14𝑥 + 15𝑥15𝑥 + 16𝑥16𝑥 + 17𝑥17𝑥 + 18𝑥18𝑥 + 19𝑥19𝑥 + + 20𝑥20𝑥 + 21𝑥21𝑥 + 22𝑥22𝑥 + 23𝑥23𝑥 + 24𝑥24𝑥 + 25𝑥25𝑥 + 26𝑥26𝑥 + 27𝑥27𝑥 + 28𝑥28𝑥 + + 29𝑥29𝑥 + 30𝑥30𝑥 = 10 Adam

A few questions about texmfcnf.lua and mtxrun in TexLive.
by amano.kenji 20 Aug '22

20 Aug '22

I'm currently using TexLive 2021 from Gentoo Linux. TexLive 2022 may behave with slight differences. * How does /usr/share/texmf-local/web2c/texmfcnf.lua override /usr/share/texmf-dist/web2c/texmfcnf.lua? According to mtxrun --configurations, /usr/share/texmf-dist comes later than /usr/share/texmf-local. It seems to me that texmf-dist should override texmf-local. * mtxrun --resolve-path '$SELFAUTOPARENT' resolves selfautoparent to '.' which is the current working directory if selfautodir is /usr. I think mtxrun refuses to accept '/' as selfautoparent and assigns the current working directory to selfautoparent. Is this a bug?

Color property of \setupurl
by Joaquín Ataz López 20 Aug '22

20 Aug '22

Good morning everyone. I have been doing some tests on the "color" property of \setupinteraction and the "color" property of \setupurl and my feeling is that the color of the hyperlinks is always controlled by \setupinteraction. Could someone clarify me in what kind of context the color of a hyperlink is controlled by the "color" property of \setupurl? -- Joaquín Ataz López Derecho civil Universidad de Murcia | jal(a)um.es

Write a long chapter title in two lines
by Jeong Dal 19 Aug '22

19 Aug '22

Dear all, A few days ago, I sent an email as follows. But it is linked to another subject because I choose reply of another subject. So, I send the same mail again. Thank you for reading. Best regards, Dalyoung ********** I’d like to write a long chapter title in two lines if it is longer than the textwidth. It is OK when I use just bigger fonts. But it writes the long title in one line if I use outlined font for title as in MWE. Is there a way to write it in two lines using the outlined font? Thanks, Best regards, Dalyoung \startuseMPgraphic{outlineT} draw outlinetext.b (\MPvar{tt}) (withcolor .75white) (withcolor .725blue withpen pencircle scaled .75pt);%\MPvar{thick}); \stopuseMPgraphic \definefont[BigFontOne][NotoSansCJKkr-Bold sa 4] \define[1]\outlineTitle{\useMPgraphic{outlineT}{tt="#1"}} \setuphead[chapter] [textcommand=\outlineTitle, style=\BigFontOne, numbercommand=\outlineTitle, % align = middle, number=yes] \setupexternalfigures[location={default,local,global}] %\definefont[fancy][Zapfino at 24pt] \starttext \startchapter[title={Very Long Long Long Title}] \startcombination[3*1] {\externalfigure[cow] [combination]}{cow} {\externalfigure[mill] [combination]}{mill} {\externalfigure[hacker][combination]}{hacker} \stopcombination \stopchapter \stoptext

Using MathTime Pro 2 fonts in ConTeXt
by Sebastian Leonardo Molina Diaz 18 Aug '22

18 Aug '22

Years ago it was asked if someone could provide a typescript for the MathTime Pro2 fonts. However, the conversation ended nowhere, so I want to ask how should I format a typescript to use such fonts. Below is the link of the related conversation: https://mailman.ntg.nl/pipermail/ntg-context/2010/051611.html Thanks in advance. -- *Aviso legal:* El contenido de este mensaje y los archivos adjuntos son confidenciales y de uso exclusivo de la Universidad Nacional de Colombia.

Re: [NTG-context] How can I make a Gentoo Linux package for ConTeXt LMTX?

Right now, the only files available for download that I'm aware of are the latest versions. This is problematic from a reproducibility standpoint, since if you have multiple people, say, writing a large textbook, it would make sense that they wouldn't want to upgrade their systems constantly in case something breaks. These people can easily just avoid upgrades, but if someone new joins the team, they can only download the newest version. However, that won't necessarily match the older version that everyone else has, which can lead to problems. Having older versions available would also help in the case of major short-term regressions, since users would be able to (manually) downgrade to an older version if necessary. An easy solution to this would be the following: instead of overwriting the whole "/install-lmtx/" tree on every update, you would install all the new files to something like "/install-lmtx-2022-08-07/", then have "/install-lmtx/" be a symlink to the latest "/install-lmtx-YYYY-MM-DD/". I don't think that this would be very hard to implement from a technical perspective, and the only downside that I can think of would be extra disk space used. This is a fairly common implementation among other software. One other solution would be to have "dl.contextgarden.net" mirror a zip/binary combo once every few months or so. These would often be out of date, but they would provide a stable archive that would be useful in cases like this. This is just a suggestion though; it's not something that I personally need, although I see how it could be potentially valuable for others. Thanks, -- Max

Suggestions for project structures, environment inheritance, local overrides
by denis.maier＠unibe.ch 17 Aug '22

17 Aug '22

Hi everyone One of my current main projects where I use ConTeXt is typesetting journal articles from xml sources. As the journal appears only online, we've decided to publish each article individually. I have a working setup, but I occasionally ponder whether I could make things more smootly. Currently, my folder structure looks roughly like this : 2022 -- _assets -- article1 ---- source ---- md ---- xml ---- pdf ---- html -- article2 etc. Usually, I receive Word files that get transformed via pandoc to markdown, polished, and from there to XML. HTML is produced via XSLT, PDF via ConTeXt. Transformations are performed with the help of a makefile. The _assets folder contains a bunch of helper files, scripts, and two environment files used by ConTeXt : jats.tex -> contains the setup for JATS XML layout.tex -> contains layout settings Now, this mostly works, but I sometimes struggle with things like overrides/additions for specific articles. Say, I have the global definitions, but I need to make small changes for one specific article? Or, I need to add something to one specific article, but I don't want to add this to the <environment> files. I guess my question is something like this : - How could a painless solution for such a scenario look like? - Should you just load multiple environment files and override earlier settings? (How would that work with xml setups?) Best, Denis

Bug (?) with \placefigure[right]
by Bruce Horrocks 16 Aug '22

16 Aug '22

Things start to go awry after about 5 or 6 iterations, 12 shows it up clearly with three or so nearly blank (except for the subject) pages produced. \setuppapersize [A5] [A5] \starttext \dorecurse{12}{ \subject{Some heading} \placefigure[right] {} {\externalfigure[cow.pdf] [width=3cm]} \input lorem } \stoptext I actually want \placefigure[right,none] in my real doc but that also goes awry. LMTX current version: 2022.08.05 11:44 My actual requirement is to have a set of short biographies, including a small 'passport' photo, for each contributor to a book. So any suggestions on how to wrap text around the photo that avoids this issue would be welcome. — Bruce Horrocks Hampshire, UK

\nolimits no effect in LMTX
by Stefan Haller 16 Aug '22

16 Aug '22

Hello, The \nolimits macro has no effect in LMTX, but works fine in the context mkiv version of my texlive installation. Small example: \starttext \startformula \sum\nolimits_{i=1}^{n} a_i \stopformula \stoptext In LMTX the sub- and superscripts are incorrectly placed below and above the sum operator. Can someone have a look what's going wrong? Thanks in advance! Best regards, Stefan Haller
