Wiki update
by Taco Hoekwater 16 Jan '24

16 Jan '24

Hi all, I just updated the wiki ConTeXt to 20240108. The <context> tag on the wiki by default uses luametatex (LMTX), but if you want luatex instead (MKIV), you can still do that by using <context mode=“mkiv”>. There have been some problems recently because Hans’ new binaries needed a newer version of various system libraries. I fixed that this morning after Hraban spotted the issue, but it means that there may be wiki pages with ConTeXt processing errors in them now. These can be recognised by either the colorised “error” output, or some cryptic “copy failed” message instead of the actual output. If you see one of those pages, Edit it. For the colorised “error” output you need to make a tiny change to the example itself (because that “error” output is correct as far as the wiki software can tell, so you have to force it to regenerate). For the “copy failed” case, you just have to start an edit and then immediately save again. The wiki will autogenerate any missing examples on save.

Limit of the size of the email message is 100KB.
by luigi scarso 16 Jan '24

16 Jan '24

Hi all, the ml has (as always as far as I can remember) the limit of 100KB for the maximum size of the message. I have noticed that lately several messages are over the limit, and all I can do is write to the sender and discard the message, and this could happen a couple of days later the message has been received. So...just stay within the limit, if you can. -- luigi

Perhaps I need to go and contemplate the sins of my formatting choices... :-) Jim

issue with \setuptyping (and XML sources)
by Pablo Rodriguez 14 Jan '24

14 Jan '24

Dear list, the issue I’m experiencing comes from XML sources typeset with ConTeXt. I have tried, but I found no way to get a minimal sample. For code fragments in the XML source, I use: \bgroup\xmlprettyprinttext{#1}{none}\egroup To which I apply: \setuptyping [style={\tt\wider}, margin=yes, align={right, broad}, blank={3*halfline}, before={\blank[3*halfline]}, after={\blank[3*halfline]}] Could anyone be so kind to explain me why the first three options from \setuptyping work (style, margin and alignment), and the other three don’t work at all? Sorry, I think it has to be a stupid mistake of mine (but I don’t know which one it might be). Many thanks for your help, Pablo

font error in float placement?
by Henning Hraban Ramm 14 Jan '24

14 Jan '24

(LMTX, latest beta with self-compiled binary on OSX-intel.) With my book, I run into an Lua error while placing a sidefloat. If I comment \externalfigure or replace the image with a different one, the error disappears. I can’t reproduce it in a minimal example, so I guess it depends on the current surroundings. Since it points to some font handling and the figure is a PDF containing fonts, I guess it might depend on the new handling of fonts in PDFs, but it doesn’t change regardless of \setupexternalfigures[compact=preset:merge] or other settings.

Why the way key-value argument is called affected the document's output?
by 111414w＠gmail.com 13 Jan '24

13 Jan '24

Hi, I was cleaning and formatting my context file and then when I compiled it, the output I got introduced extra vertical spacings at the section headings that weren't there in the previous compilations. I had to spend enormous amount of time trying to fix it so to emulate my previous outputs. Turns out the problem was how I called one of the key-value argument in the document. I really wanna know the reason why it did influenced the output? Provided below is the minimal source code (and it is producing different outputs, meaning the vertical spacings are not same, on my device running the version released in the September and also tested with the latest release.) """ %% differences in outputs, for how "grid=yes" is called. %% Type 1. %\setuplayout[grid=yes] %% Type 2. %\setuplayout[ %grid=yes %] \setuphead[section][grid=low] %% needed to observe the output difference \starttext \title{Alpha} \subsection{Beta} \input{knuth} \stoptext """ Best regards, Ali

Width of captions and notes in outer margin not correct on even pages
by Milan cel Mare 09 Jan '24

09 Jan '24

Hi, I have observed that the widths of captions and also notes on even pages is not as I would expect them to be. Reading through the documentation I figured out that the width for captions has to be set manually when they are placed in the outer margin. I did so by setting it to width=\outermarginwidth. But it seems that for captions the width is derived from the inner margin width on even pages. The width of notes in the outer margin placed with \inouter is also off on even pages. They are too narrow and do not "fill" the available space (things seems to work for notes in inner margins though). Here is an example: \setuppapersize[A4] \setuplayout[backspace=40mm, width=100mm, leftmargindistance=5mm, leftmargin=30mm, rightmargindistance=5mm, rightmargin=50mm, topspace=10mm] \setuppagenumbering[alternative=doublesided] \setupcaptions[location={outermargin, low}, width=\outermarginwidth, headcolor=red, color=green, style={\tfx\setupinterlinespace}, align=width] \setupexternalfigures[location=default] \setupmargindata[style={\tfx}, stack=yes] \setupmargindata[inouter][color=orange] \setupmargindata[ininner][color=blue] \showframe \starttext \section{Margin Tests} \input knuth Some more stuff\inouter{Some multi-line text to be placed in the outer margin to check whether it is positioned correctly.} to read\inouter{Another multi-line text to be placed in the outer margin to check whether it is positioned correctly.}. \startplacefigure[title={A lengthy caption perfectly suited to perform some tests, which cause lines to wrap.}] {\externalfigure[cow][maxwidth=80mm]} \stopplacefigure More stuff\ininner{A1, A2, A3, A4 are well-known paper formats used in Europe and in some other places.}. \input zapf Some more stuff\inouter{Some multi-line text to be placed in the outer margin to check whether it is positioned correctly.} to read. \startplacefigure[title=A SVG test with a long caption to cause line wraps.] {\externalfigure[cow][maxwidth=70mm]} \stopplacefigure More stuff\ininner{A1, A2, A3, A4 are well-known paper formats used in Europe and in some other places.} to read. \input knuth \stoptext As a workaround the width for captions can be set to width=\rightmarginwidth, but how can I solve the issue with the notes?

Setuphead issue!

Hi, I'm a bit puzzled by the mkiv /setuphead/ command of ConTeXt!

Now I'd like to have _no vertical space_ before and after the header. I've tried just that by setting either *before=* and *after=* and *before=\blank[none]* and *after=\blank[none]*. But none of these seem to work. Any idea? Gerard --

MetaFun path joiners && and &&&& do not like single point paths
by Gavin 09 Jan '24

09 Jan '24

Hi MetaFun fans, Following a suggestion of Hans, I experimented with && and &&& and &&&& for joining paths in MetaFun. The joiner &&& produces one long path, but && and &&&& seem to produce a disconnected path which includes all the original paths. However, if one of the paths is a single point, then it connects it. MWE below. I spotted this on my globes module, where we saw an extra line appear for a very specific orientation of the globe. I guessed that this orientation had an island right on the horizon, so that only one boundary point was visible, creating a singe point path for that island. I should probably fix my module so it doesn’t do that. However, it might be nice to have && and &&&& deal with this situation gracefully.

Hi, With the build farm still down I now use an alternative build, that is, I run a compile script on s bunch of machines and hope for the best. In the process I decided to drop 32 bit installers (users can generate bins themselves if needed). I also drop bsd version and just use the latest. For OSX I use a retired macbook air that Hans vd Meer sent me that has an old operating system but new enough so that its xcode can make intel and arm binaries. The linux binaries have teh problem that they depend on glibc versions and I'm assuming a reasonable up to date system so I use opensuse leap (which is not even that new with it comes to glibc but we use it on servers here). texmf-win64 : laptop (linux subsystem on windows) texmf-windows-arm64 : laptop (native visual studio) texmf-linux-64 : linux-opensuse-leap (latest leap 15) texmf-linux-aarch64 : raspberrypi (latest debian) texmf-linuxmusl-64 : linux-alpine-64 (whatever) texmf-osx-64 : airbook/118/hvdm (older xcode) texmf-osx-arm64 : airbook/118/hvdm (older xcode) texmf-freebsd-amd64 : openbsd-amd64-14 (latest) texmf-openbsd-amd64 : openbsd-amd64-74 (latest) If your platform doesn't work you can download the texmf.zip, context-texmf.zip and installation.pdf and start from there: create the tree, compile from source, move the binaries and it should just work.

multipage metapost output from ConTeXt
by Emanuel Han 06 Jan '24

06 Jan '24

How can I achieve multipage metapost output from ConTeXt? The result should be a multipage pdf. It contains just a metapost graphic per page. The graphic has always the same bounding box and evolves from page to page: Some elements to be drawn are added, and some others would ideally also be removed, while keeping elements which has already been drawn on previous pages. I can manage when it is not possible to remove elements (in that case I'll just cover them with a covering element). I saw that it is possible to achieve my goal with standalone metapost, as described here: https://tex.stackexchange.com/questions/471662/mptopdf-is-multipage-output-… But I'll need to achieve this with Metapost inside ConTeXt because I use labels in Metapost which print text in Japanese, Korean , Arabic and Roman script: Thanks to ConTeXt, I can define appropriate fonts for each script. All this works already in my working example. The only unsolved problem is to ship out multiple pages. For the minimal working example, I didn't remove the font defining part, because having 4 different fonts is a condition of my use case. The graphic on the other hand is some simple dummy nonsense graphic not from my project. The graphic is in the provided example drawn as a summing up of layered drawing steps (6 steps, to be precise), so no removing is implemented here (because I don't know how that would be done). If each of the figures 1 to 6 of my mwe can be put alone on a page, I'd be already very happy. Now, they're put on top of each other all on the same single page, also on top of figure 0. The desired multipage pdf will be used in presentation mode of a pdf viewer and skipped forward and backward from page to page (that is from drawing step to drawing step). mwe: \enableregime[utf] % enable unicoded input \definefontfamily [RomanFont] [rm] [calluna] \definefontfamily [KoreanFont] [rm] [applemyungjo] \definefontfamily [JapaneseFont] [rm] [hannotatesc] \definefontfeature [fea] [mode=node,language=dflt,script=arab, init=yes, medi=yes, fina=yes, isol=yes, calt=yes, rlig=yes, tlig=yes, trep=yes, curs=yes, kern=yes, mark=yes ] \starttypescript [serif] [notonaskharabic] \definefontsynonym [notonaskharabic-Light] [name:notonaskharabic] [features=fea] \definefontsynonym [notonaskharabic-Bold] [name:notonaskharabic] [features=fea] \definefontsynonym [notonaskharabic-Italic] [name:notonaskharabic] [features=fea] \definefontsynonym [notonaskharabic-Bold-Italic] [name:notonaskharabic] [features=fea] \stoptypescript \starttypescript [serif] [notonaskharabic] \usetypescript[serif][fallback] \definefontsynonym [Serif] [notonaskharabic-Light] [features=fea] \definefontsynonym [SerifItalic] [notonaskharabic-Italic] [features=fea] \definefontsynonym [SerifBold] [notonaskharabic-Bold] [features=fea] \definefontsynonym [SerifBoldItalic] [notonaskharabic-Bold-Italic] [features=fea] \stoptypescript \starttypescript [notonaskharabic] \definetypeface [notonaskharabic] [rm] [serif] [notonaskharabic] [default] \stoptypescript \usetypescript[notonaskharabic] \setupbodyfont [RomanFont] \starttext \startMPcode picture p[]; path bb; %bounding box z0 = (0,0); z1 = (60,40); z2 = (40,90); z3 = (10,70); z4 = (30,50); z5 = (90,70); z6 = (-10,70); path A; A = z0..z1..z2..z3..z4 ; pair AStartPoint; AStartPoint = point 0 of A; pair AEndPoint; AEndPoint = point 4 of A; path B; B = z5..z6; pair BStartPoint; BStartPoint = point 0 of B; pair BEndPoint; BEndPoint = point 1 of B; path C; C = AStartPoint..AEndPoint; % drawing steps: p1:=image( draw A withcolor red; ); p2:=image( label(textext("\JapaneseFont 日本語"), AEndPoint); ); p3:=image( label(textext("\notonaskharabic \textdir TRT دانگ") scaled 1.2, AStartPoint); ); p4:=image( label(textext("\KoreanFont 한국어"), BStartPoint); ); p5:=image( label(textext("\RomanFont bāng"), BEndPoint); draw C withcolor green; ); p6:=image( draw B withcolor blue; ); beginfig(0); %% the whole picture for the common bbox for k=1 upto 6: draw p[k]; endfor bb:=bbox(currentpicture); endfig; for $=1 upto 6: beginfig($); for k=1 upto $: draw p[k]; endfor setbounds currentpicture to bb; endfig; endfor \stopMPcode \stoptext

Local alternative to \input
by Jeroen 04 Jan '24

04 Jan '24

I have a document that is getting a lot of mark-up instructions for creating tables and placing figures. I would like to move this out of the main text flow. The easiest way would be using \input, but i rather place all this at the bottom of the file and just refer to it with something like \localinput or so to a textblock at the bottom of the same file. What would be the easiest way to implement this?

underbrace label across two lines
by Dean Hung 20 Dec '23

Hi list, Following on from Aditya's solution to my previous question, I have run into a separate issue and would appreciate any assistance. Sometimes text under the underbrace can become quite long, and should be split into two (or more) lines. In the example below, "firstline" should be the top line of the underbrace label, and "secondline" should be on the lower line of the underbrace label, but as it stands, both are printed on the same line. \underbrace[mindepth=0.5cm]{\tf x+y+z}_{\vrule width 0pt height 0.5cm\relax\text{firstline secondline}} I have tried using \\ and \crlf, but to no avail. Any help would be greatly appreciated! Dean

install-modules script and git URLs
by Pablo Rodriguez 20 Dec '23

Hi Hraban and Taco, the install-modules script doesn’t allow .tar.gz as compression format to install modules. .tar.gz seems to be the compression format offered for modules that are uploaded using a git URL. Hraban explained in August that thee server could be configured to get .zip compression for modules in git checkout. Sorry, I know that you are both very busy, but could it be this issue fixed? Using git to upload module versions is way more easy than uploading .zip files. Many thanks for your help to both, Pablo

Seeking advice for module that draws globes
by Gavin 19 Dec '23

19 Dec '23

Hello ConTeXters, I wrote a little ConTeXt module for drawing globes. I would love some advice on how to improve it and share it. The code is quite short (about 250 lines). Most of the work is done by Lua, which reads the data files and calculates paths. These paths are passed to MetaFun, which draws the globe. Below is an example document with the output. (I attached a small .png of the output for the mailing list. The output PDF has excessive detail.) The module (code and data) is on GitHub at https://github.com/GavinPolhemus/luageo. \usemodule [luageo] \startMPpage GlobeDiameter = 10cm ; fill fullcircle scaled GlobeDiameter withcolor .9white ; % Fill a circle with the water color. drawglobe(23, 0) scaled GlobeDiameter withcolor .75white ;% Draw the land, centered on the given latitude and longitude. draw fullcircle scaled GlobeDiameter withcolor black ; % Add a border, if you want. \stopMPpage I am a novice at both Lua and MetaPost. I’m also new to Git and have never shared anything of substance with the ConTeXt community. (This barely counts as substantive, but I figure it’s best to start small.) I’m sure many of you could find opportunities for improvement with even a quick glance at the code. I welcome anything, from advice on performance to suggestions about the license. My most pressing questions are these: 1. How do I avoid redrawing diagrams with every typeset? The globe above takes about 0.7s, which is not bad, but it adds up in a book with many diagrams. 2. How do I organize this according to TDS for sharing? I know what TDS is and why it’s important, but that’s about it! 3. Should I be creating a namespace for this module, or launching a separate MetaFun instance? I have a general sense of what “namespace” and “instance” mean is this context, but I don’t know the consequences or the how-to. I’d like to share this module, even though the potential demand is tiny, at best. I’m going through the Module Writing Guidelines (https://wiki.contextgarden.net/Modules#Module_writing_guidelines) but there is a lot that I don’t understand in those instructions. Questions 2 and 3 above relate to the instructions that are most mysterious to me. I think I can figure most of the others out. I have been using ConTeXt for several years to write a high school physics textbook (along with the problem sets, tests, equations sheets, etc.). I wrote this module because I needed globes in some diagrams. I found an old MetaPost tool, mp-geo, that seemed to have the right ingredients, but I couldn’t get it to work, so I wrote my own tool using the data files from mp-geo. Hans and others on the list gave me valuable advice for these globes a couple years ago (and gave other valuable advice on all sorts of things before and since). Many diagrams in my physics book use TikZ and pgfplots. I'd like to convert everything to MetaFun. I think the best way will be writing a few more modules for things like graphs (including polar and 3D plots), simple circuits, simple Feynman diagrams, etc. I’m hoping that these would be useful to the ConTeXt community. The luageo module has the basic design I’d like to use for the others: Lua for data handling and calculations, producing paths that are drawn by MetaFun. With some mentoring from the generous ConTeXt community, I’m hoping we can provide MetaFun alternatives to some of the TikZ libraries. I have an alpha version of luagraph by Alan Braslau, which was helpful in designing luageo. Working on luagraph is my next project. Gavin

increase vertical between underbrace and equation

Hi ConText friends, I am trying to increase the vertical distance between the underbrace and the part of the equation above the underbrace. \startformula \underbrace{x+y+z}_{\blank[1cm]\mathrm{my text here}} \stopformula I've tried using \blank and \vspace, but to no avail. For example: \underbrace{x+y+z}_{\blank[1cm]\mathrm{my text here}} ...does not work. The documentation on underbrace (and overbrace, underbracket, etc...) in the ContextGarden wiki seems to be very limited, and I was not able to find any user-supplied arguments for increasing this vertical distance. There are various solutions available for LaTex, and they require external packages (e.g., BigStrut, vphantom) that redefine the strut height. I hope I'm missing something simple... Any help would be greatly appreciated! DY Hung

How to input first n lines from file?

16 Dec '23

With the command `\input file`, I can input the entire contents of `file.tex`. Is there a way to limit it to the first n lines, for instance, something like `\input[10]` file would only input the first 10 lines from `file.tex` and ignore the rest of the lines. --Joel

LMTX: Command handling, Interface between TeX and Lua
by Gerion Entrup 14 Dec '23

14 Dec '23

Hi, I'd like to understand more of the inner workings of LMTX. When I understand it right, most of the code is now processed in Lua but I was not able to find it. For example, I tried to find out how setupitemgroup is handled (just as an example of a more complex command). The wiki has a (kind of) autogenerated description: https://wiki.contextgarden.net/Command/setupitemgroup I found the data for this (at least this is my guess) here: tex/texmf-context/tex/context/interface/mkiv/i-itemgroup.xml Are these xml files created by hand or somehow generated? Now, when I use `\setupitemgroup[itemize:1][symbol=3,itemalign=middle]`: How are the arguments handled and is this a generic process or specific to each command? Is there a simple way to define a new command/environment and handle the keyword arguments in Lua? For example defining a frontend command like this: \startsomething[firstword={Some},secondword={Text}] Body \stopsomething which I can handle in some lua code like this: function something(firstword, secondword, body) tex.print(firstword) tex.print(secondword) tex.print(body) end Are there any resources beside the context code itself where I can learn that?

ConTeXt support for Nova text editor (MacOS)
by Paul Mazaitis 09 Dec '23

09 Dec '23

Hello, list! I'm working on a ConTeXt language extension for the Nova editor by Panic software (https://nova.app/) The extension is here: https://github.com/pmazaitis/nova-context/releases/tag/0.6.0 ...currently in beta, but fairly functional. This version of the extension supports: * Syntax Highlighting * Folding for (most) environments * Navigating by Symbols (headings: chapter, section, etc.) * Spell-checking of body text and section titles * Managing builds with Nova's tasks system (As an aside, this extension uses an updated version of the ConTeXt tree-sitter parser [https://github.com/pmazaitis/tree-sitter-context] that can now recognize (most) environments and use them to parse out the document hierarchy.) Limitations at the moment: not all environments are supported (only those with \start and \stop commands right now), and the extension only supports English. Happy for any bug reports, etc., -Paul

framed: rounded corner oddity

Hi, in my ConTeXt book, some examples for \framed with rounded corners look odd, as if the MetaPost calculation of rounded corners fails. I can’t find a minimal example that shows the problem, and I can’t imagine which of the settings in my extensive environment would cause it. Find below the code that works on its own, but causes the results as shown in the attachments within my book. There’s nowhere a \setupframed, and nothing that should influence MetaPost. Do you have any clue for what I should look?

\unit{mercury} renders as m (meter) and \unit{millimetermercury} doesn't work as expected
by Marco Patzer 05 Dec '23

05 Dec '23

Hi! I'm struggling with the rendering of a particular liquid metal: %% renders as m (meter), not as Hg \unit{mercury} %% renders as mm·m, not as mmHg \unit{millimetermercury} This is strange, since both “mercury” and “millimetermercury” are defined in phys-dim.lua. To get mercury recognised as a unit this can be used: \registerunitshortcut [mercury=mercury] Now \unit{mercury} renders correctly as Hg. Why is that \registerunitshortcut necessary? Is it even correct to use it like this? However, even then millimetermercury doesn't render correctly: %% renders as mm·Hg, not as mmHg \unit{millimetermercury} How to get millimetermercury render as mmHg? And “inch mercury” render as inHg? I can't find “inchmercury” in phys-dim.lua, only “millimetermercury”, should it be added? Example: %% \enabletrackers [physics.units] %% inch should render as “in” %% \setupunittext [inch=in] \starttext \unit{mercury}\crlf %% renders: mm · m \unit{12 millimetermercury}\crlf %% renders: mm · m \unit{12 inchmercury}\crlf %% renders: in · m %% why is this necessary to get mercury rendered as Hg? \registerunitshortcut [mercury=mercury] \unit{12 millimetermercury}\crlf %% renders: mm · Hg \unit{12 inch mercury}\crlf %% renders: in · Hg \stoptext Questions: 1) Why is \unit{mercury} not working, although it's listed in phys-dim.lua? 2) Is the call \registerunitshortcut [mercury=mercury] necessary/correct? 3) How to make \unit{millimetermercury} render as mmHg and \unit{inch mercury} render as inHg?

mathalignment; alignment of columns
by wolfgangbackes＠mail.de 28 Nov '23

28 Nov '23

Something as elementary as "mathenvironment" can't really be faulty, can it? According to my recent tests, a mathalignment environment does not seem to react (any more) to the values of the "align" option. The source code hab been rendered correctly a few years ago, Minimal example 1: \starttext \startformula \startmathalignment[n=2,align={left, right}] \NC always aligned to the right \NC = u + at, \NR \NC d \NC = ut + \frac12 at^2. \NR \stopmathalignment \stopformula \stoptext Despite "align={left, right}", the first column is aligned to the right and the second to the left. This does not change, no matter which values I assign to "align", for example align={middle, middle}. The align option is also ignored in the case of other column numbers., for example: \starttext \startformula \startmathalignment[n=1,align=left] \NC This single column should \NR \NC be left-aligned, \NR \NC but it is centered. \NR \stopmathalignment \stopformula \stoptext What am I missing here? Where is my mistake? Regards Wolfgang

In the MWE, is there a more "ConTeXt way" to accomplish the task of adding captions to tables, figures, blockquotes, etc? % SOT \startbuffer[demo] <body> <p><span class="caption">Caption 1 <a data-type="tbl" name="lbl-1"/></span></p> <table>table 1 with caption</table> <table>table 2 without caption</table> <p><span class="caption">Caption 3 <a data-type="tbl" name="lbl-2"/></span></p> <table>table 3 with caption</table> </body> \stopbuffer \startxmlsetups xml:demo \xmlsetsetup{\xmldocument}{*}{-} \xmlsetsetup{\xmldocument}{a|p|body|table}{xml:*} \xmlsetsetup{\xmldocument}{span[@class='caption']}{xml:span} \define\CaptionText{} \define\AnchorXref{} \stopxmlsetups \startxmlsetups xml:span \define\CaptionText{\xmlflush{#1}} \stopxmlsetups \startxmlsetups xml:a \define\AnchorXref{\xmlatt{#1}{data-type}-\xmlatt{#1}{name}} \stopxmlsetups \startxmlsetups xml:body \xmlflush{#1} \stopxmlsetups \startxmlsetups xml:p \xmlflush{#1}\par \stopxmlsetups \startxmlsetups xml:table \blank \doifelsetext{\CaptionText}{% \startplacetable[ title={\ignorespaces\CaptionText{}\removeunwantedspaces.}, reference={\AnchorXref} ] \define\CaptionText{} \define\AnchorXref{} }{ \startplacetable } \startembeddedxtable \startxtablebody[body] \startxrow \startxcell \xmlflush{#1} \stopxcell \stopxrow \stopxtablebody \stopembeddedxtable \stopplacetable \blank \stopxmlsetups \xmlregistersetup{xml:demo} \starttext \xmlprocessbuffer{demo}{demo}{} \stoptext % EOT

Compatibility Issue with TikZ/Spy Library in ConTeXt: Seeking Solutions
by wolfgangbackes＠mail.de 24 Nov '23

24 Nov '23

Hello, I am reaching out to seek assistance regarding a compatibility issue I have encountered after installing ConTeXt on a new computer. The problem arises when attempting to compile documents that utilize the spy library; the LuaTeX engine returns the following error message: "error (luacall): invalid number mtx-context | fatal error: return code: 1" Unfortunately, the error message provides no additional clues. To investigate further, I created a minimal example, which you can easily verify at https://context-on-web.eu/. The example employs the spy library within a TikZ environment. Surprisingly, the same example runs without error on my local LaTeX engine, indicating a potential compatibility issue between ConTeXt and the spy library. Here is the minimal example for your reference: \starttext \usemodule[tikz] \usetikzlibrary {spy} \starttikzpicture[spy using overlays={size=12mm}] \draw (0,0) -- (1,1) -- (2,-1); \spy [blue,magnification=5] on (1,1) in node at (3,0); \stoptikzpicture \stoptext I am curious if anyone else has encountered a similar problem with the spy library and ConTeXt and, if so, if there is a known solution. Any insights or guidance would be greatly appreciated. Thank you for your time and assistance. Best regards, Wolfgang Backes

Dear List, After a few changes i have here an example: It works, but what I wanted to know is why are there round brackets after writing \starttheroem if i compile it. Should be without round brackets. I have the following example, the text was in a PDF from 2008, called: Theorems in ConTeXt, and also my text with the margin: \definemargindata [MyInMargin][inright] \definemarginframed[MyInMargin][topframe=on,bottomframe=on,rulethickness=1pt,width=1cm] \margintext{\blackrule[color=black, height=0.25ex, width=1cm]\\}\blackrule[color=black, height=0.25ex, width=7cm] \setupenumerations [ before={\blank[big]}, after={\blank[big]}, location=serried, width=broad, distance=0.5em, headstyle=bold, titlestyle=normal, way=bytext, conversion=numbers] \defineenumeration [theorem] [ text=Theorem, title=yes, style=italic, list=all, listtext={Theorem }] \starttext \margintext{2.1.1}{\starttheorem {The square on the hypotenuse is equal to the sum of the squares on the other two sides.

externalfigure crashed
by Hans van der Meer 22 Nov '23

22 Nov '23

When \externalfigure could not find the file it used to graciously place a rectangle kindly telling the user that the file has not been found. But now, however, it seems the default in this case is a crash. Very annoying in comparison with the earlier behaviour. I might make a mistake, but the MWE is as simple as can be. The filename is test.jpeg, then this runs ok: \starttext \externalfigure[test.jpeg][] \stoptext But this crashes, see the log: \starttext \externalfigure[test.jpg][] \stoptext yours sincerely dr.

Re: xmlpos values doubled
by Benjamin Buchmuller 22 Nov '23

22 Nov '23

Hi list, I came across this old thread as I was trying to use \xmlpos{#1} to "dynamically" create references such as \item[mystep:\xmlpos{#1}] to be referenced when other elements of this node are parsed at a later point. In fact, it seems that \xmlpos{#1} returns duplicate values. This might indeed be the intended meaning of \xmlpos{#1} as it seems related to the XML query foo/bar/index() which only looks up the position in the parent node. (I noticed that if I run this repeatedly, I get somehow different values from times to times. I can't say why.) Anyways, I was wondering if there is a TeX command to access the absolute position of an element in the tree? Similar to foo/bar[rootposition()] (or foo/bar[order()]? – Can't make sense of the entry in the XML manual.) Thank you for your help!

Markdown to HTML cross-references
by Thangalin 22 Nov '23

22 Nov '23

Hi list, I'm looking to implement a consistent syntax for cross-references in KeenWrite <https://keenwrite.com/> and am wondering what you think would make the most sense for translating into ConTeXt commands. First, some background (the first two give an overview, the others are cross-reference references for various syntaxes): - https://talk.commonmark.org/t/cross-references-and-citations/4013/7 - https://thesynack.com/posts/markdown-captions - https://quarto.org/docs/authoring/cross-references.html - https://mystmd.org/guide/cross-references - https://lierdakil.github.io/pandoc-crossref - https://github.com/tomduck/pandoc-eqnos I'm leaning towards the following syntax: Markdown Item (table, blockquote, TeX block, figure, code, R chunk, etc.) : caption text {#type:label} See [@type:label] for details. There's a unit test that shows what's currently being generated with a number of examples for images, tables, blockquotes, internationalization, and so on: https://gitlab.com/DaveJarvis/KeenWrite/-/blob/main/src/test/java/com/keenw… The code is a work-in-progress; so the tests may have changed depending on if/when you view the Java source code. Presently, the captions produce anchor references, mostly. The following seems easier to typeset using ConTeXt: <p><span class="caption">Meschiya Lake - Lucky Devil <a data-type="lyrics" name="blues" /></span></p> This diverges from the HTML specification for tables (table/caption) and figures (figure/figcaption). It would also mean having to write ConTeXt macros that flip the spans and anchors to produce a caption such as: *Lyrics 1.1.* Meschiya Lake - Lucky Devil While there are plenty of ways of presenting captions (e.g., multi-column images with sub-figure numbers) the majority of cross-references are to a single "thing" with a single "caption". What are your thoughts on this proposal? (Keeping in mind I'm the only person working on KeenWrite and while I'm trying to keep the syntax compatible with pandoc, implementing the full pandoc-crossref syntax is out of scope for me. Thank you!

Drawing calligraphy practice grid in metafun
by Andres Conrado Montoya 21 Nov '23

21 Nov '23

Hello list I've been working on a little project of mine. I give calligraphy workshops and I have been using a nice tool created by Josselin Cuette, available at http://ductus.josselincuette.com/ to generate practice templates for interested people. However, I would prefer to have an offline solution. This adventure started with the usual insidious idea: "I could do this in ConTeXt! And this is a great opportunity to learn metafun!" A couple weeks later, I have an almost ready product! It compiles fine, but I have the following issue: The template creates a Line, composed of Sections. And uses variables to assign a measurement for the nib-width, and an amount of ascender, x-height and descender Sections (nib-widths), to compose a Line. But also, I would like to, if needed, display nib-width marks on the left side. My code so far generates marks, but only for the first Line. I think they are generated but maybe they are placed on top of each other, maybe? I'm not sure why my logic is not working. Also, if I change the amount for ascenders, descenders of x-height, the marks are not drawn correctly. My current path for a mark is a custom path emulating two unit squares, nib-width size, on top of each other, with the top one shifted a nib-width to the right. A little bit like a chess board, or a scale ruler on a map. But this would only work in Lines that have an even amount of Sections. I'm not sure how to proceed with that... I tried using unit squares, but that made things very complex, and after fumbling around I managed to get this far. If you can take a look, or have some advice, it would be greatly appreciated. I hope it is understandable.

learning about the grid
by Miguel Diaz 20 Nov '23

20 Nov '23

Hi everyone, being a newbie I just discovered how different setups for the grid may affect my (very simple) document. In the Details manual (which of course I don't understand because of my unexperience) I read that many people don't use the grid, but when I configure grid=no the whole lines of a section are printed one over the other. Playing with the options and setupinterlinespace I got the unhappily desired 1.3ex that may school requieres for the teaching programs (grid=line, interlinespace=1.3ex), but I somehow feel that's not the right way to go. 1. Why are the lines printed one over the other when grid=no? how do profis then use context without grid? 2. Is there a document where I can read how the grid is conceived to work for the many options in a simple way? thanks in advance

Problem with textstyle

Vertically aligned alternating fillers

Hi! A while back Wolfgang presented a nice solution for alternating fillers: https://www.mail-archive.com/ntg-context@ntg.nl/msg67677.html It works if the text has a constant width.

Example: \usemodule [visual] \definefiller [pavel-0] [alterntive=symbol, method=global, width=2em, leftmargin=.5em, rightmargin=.5em, symbol=\clap{.}] \definefiller [pavel-1] [pavel-0] [align=left] \definefiller [pavel-2] [pavel-0] [align=middle] \newconditional\PavelState \global\setfalse\PavelState \define\PavelFiller {\ifconditional\PavelState \global\setfalse\PavelState \filler[pavel-1]%% \else \global\settrue\PavelState \filler[pavel-2]%% \fi} \def\oneword {\getrandomnumber\n{1}{100}\fakenwords{1}{\n}} \starttext %% dots are vertically aligned \dorecurse{6}{%% Foo \PavelFiller Bar\par} \hairline %% dots are not aligned \dorecurse{6}{%% \oneword\PavelFiller\oneword\par} \stoptext Marco LMTX 2023.09.04 19:15
