\getcommacommandsize not working in lmtx
by denis.maier＠unibe.ch 02 May '22

02 May '22

Hi, I've just ran into a behaviour that runs against what is shown on the wiki, https://wiki.contextgarden.net/System_Macros/Comma_Separated_Lists Maybe a bug? The wiki says you can use \getcommacommandsize to get the length of a comma separated list, but it does not seem to work. MWE below. Best, Denis \define\somelist {foo, bar, baz} \starttext \getcommacommandsize[\somelist] \commalistsize % Expected : 3 % Actual : 1 \expandafter\getcommalistsize\expandafter[\somelist] \commalistsize % Expected : 3 % Actual : 3 \stoptext

recursion in a table
by Henning Hraban Ramm 02 May '22

02 May '22

Hi, I was playing with the example from https://wiki.contextgarden.net/Scaling_Rotating_Mirroring_Clipping#Location… and tried to put it in a tabulate: \useMPlibrary[dum] \setupexternalfigures[width=3em,height=2em,frame=on,] %\def\TXT{\ruledhbox{\bf(XyX)}} \def\TXT{\externalfigure[pic]} \starttabulate[|l|l|l|l|l|l|] \NC\NC normal\NC depth\NC fit\NC broad\NC high\NC\NR \HL \dostepwiserecurse{0}{359}{45}{% %\expanded{\setuprotate[rotation=\recurselevel]} \NC{\expanded{\recurselevel}˚}% \NC{\ruledhbox{X\rotate[location=normal,rotation=\recurselevel]{\TXT}X}}% \NC{\ruledhbox{X\rotate[location=depth,rotation=\recurselevel] {\TXT}X}}% \NC{\ruledhbox{X\rotate[location=fit,rotation=\recurselevel] {\TXT}X}}% \NC{\ruledhbox{X\rotate[location=broad,rotation=\recurselevel] {\TXT}X}}% \NC{\ruledhbox{X\rotate[location=high,rotation=\recurselevel] {\TXT}X}}% \NC\NR} % \HL % error \stoptabulate This works, but \recurselevel is always 0. I know I must expand it (like in the original example), but I can’t make it work within the tabulation. In the first column, \expanded{\recurselevel} stays 0, and rotation=\expanded{\recurselevel} gives an error, while the \setuprotate line has no effect (if I remove "rotation=\recurselevel", of course). How would that work? Also, \HL doesn’t work at the end, and the second line of the error message makes no sense: """ I expect to see \noalign only after the \cr of an alignment. Proceed, and I'll ignore this case. mtx-context | fatal error: return code: 1 """ Hraban

Fuzzy paragraph when exporting to XML
by Aditya Mahajan 01 May '22

01 May '22

Hi, I am trying to debug a bug-report for t-vim: https://github.com/adityam/filter/issues/64 Exporting with trackers=export* gives a warning: backend > export > fuzzy paragraph: I have managed to narrow it down to the attached MWE (which does not depend on the t-vim module at all). Compiling it using $context --trackers=export\* lines gives the fuzzy paragraph warning. Any hints on how to resolve this? Thanks, Aditya

Problem with a defined colour in MetaFun
by Keith McKay 29 Apr '22

29 Apr '22

Hi, In the MWE below I define an rgb colour, myColor1, using random numbers for the r, g and b components. I then use it to fill a unitsquare the size of the page, which works as expected. In the loop that follows I then use the defined colour, myColor1, along with white and the variable r to create shades of myColor1 as in the MWE below. However, myColor1 is not recognised in the loop and seems to be replaced by black, although if I use a predefined colour, in this case BurntSienna from the crayola collection, it works as expected. I have tried a number of ways to get this to work as shown in the code but without success. I would be grateful for any suggestions.

I was able to reproduce the issue just by adding \setuplayout[grid=yes] to my "standard" test files, so I shouldn't need anything else, provided that the above beta actually fixes anything. If there are still lingering issues, then having the TeX source would likely simplify things on my end. -- Max

installing modules
by Henning Hraban Ramm 28 Apr '22

28 Apr '22

Hi, while the rsync installation shown in https://wiki.contextgarden.net/Modules#ConTeXt_LMTX works well, it doesn’t install all available modules listed in modules.contextgarden.net. E.g. lua-widow-control and metaducks are missing. Why, and how can we change that? Has it to do with the t- prefix? Hraban

Fwd: lua-widow-control module error in LMTX
by Eduardo Bohoyo 27 Apr '22

27 Apr '22

Hello, Max: As I promised you this morning, I had time this evening to read more carefully all your remarks in the last mail. And now I can answer you with more basis. In my particular case, it is not necessary to consider any of the seven possible problems you describe from highest to lowest probability. The question you asked me in the first paragraph about "interesting" features in my ConTeXt code is the key. When I uncomment grid=yes in my \setuplayout, lwc makes its real appearance on the scene. I suppose that in other documents than mine, i.e. less complex, this performance would be a success. But in my file it is, considering my current aesthetic requirements, a failure. This is because for me grid=yes is a non-negotiable part of my code. As I told you this morning when I sent you my pdf without the module activated, but with the layout my way, I understand that lwc can have problems with a text whose chapters have capital letters and small caps on the first page with less text than on the following pages; with long quotations that involve paragraphs of different layout and separated from the main text; with more than one footnote in a row, with a bibliography at the end with French indentation; with vertical spaces separating two lines within the same chapter when in the dummy text there is a supposed change of scene within the narrative; with etc. etc., etc., etc... Anyway, after uncommenting grid=yes again, I will send you the log file, as you asked me. By the way, I do get some "Widow/Orphan NOT removed on page..." in spite of the rest of "successes" that move the final lines of my pages away from the result I would like, and that you have seen in the pdf I sent you this morning. Do you want the new pdf with lwc actually acting on my file? Then you can get a better idea of what I mean by the end of some pages when I comment grid=yes (apart from the mischief that happens with the horizontal spaces in some paragraphs of the bibliographic section). Or, if you prefer, and you need more feedback, I can send you my current code to use it as a test bench for " daring " texts.

pull quotes
by jbf 27 Apr '22

27 Apr '22

Hi list, Back in March, Garulfo asked a question about pull quotes and offered two links by way of example. One of the styles in those links interested me in particular, namely https://www.societal.fr/sites/societal/files/old_site/societal-46-6-boiteux… I know how to make a pull quote in general terms, but Garulfo's question was quite specific - was there a preferred way to set an intercolumn pull quote, and presumably he also meant of the kind found in the link above. I did not see any response to his question so perhaps he received one off-list. I too would be interested to know how one might achieve precisely the kind in the example, which features a 'bracketed' pull quote. Has anyone attempted that? Julian

cropoffset reduces paper size
by Henning Hraban Ramm 25 Apr '22

25 Apr '22

Hi, at least in the current and previous LMTX beta, the paper size gets reduced if I use cropoffset as well as \setupinteractionscreen. (It is known that the PDF box settings only work with the latter.) In the MWE below, paper size gets reduced by cropoffset: \setuppapersize[A4] \setuplayout[ cropoffset=10mm, ] \setupinteractionscreen[ width=max,height=max, ] \starttext \showframe \samplefile{knuth} \stoptext If I set: \setuppapersize[A4][A4,oversized] \setuplayout[ marking=on, location=middle, cropoffset=7.5mm, ] Then the resulting paper size is A4, because the "oversized" factor is nulled by the crop offset. While I can work around this "feature", the behaviour is different from earlier versions. Can’t check with MkIV, since that doesn’t work any more, as reported by Pablo et al. Hraban

Why can I no longer place \input inside table after update?
by Joel 23 Apr '22

23 Apr '22

After I ran an update on ConTeXt, my code gets an error: \starttext \starttabulate[|p(.3\textwidth)|p(.7\textwidth)|] \HL \NC {\bf Term} \NC {\bf Definition} \NC\NR \HL \input test2.tex \HL \stoptabulate \stoptext File test2.tex contains "\NC {\bf Term} \NC {\bf Definition} \NC\NR". I also tried defining a macro earlier in the document... \define[2]\tablewordis{% \NC \NC \NC\NR \NC #1 \NC #2 \NC\NR } ...then placing that in test2.tex, e.g.: \tablewordis{my word}{my definition} I get the error: " The file ended when scanning an argument." Before the update, this code worked fine. How can I \input a file while inside a table environment, as above? Thanks, --Joel

New Tool: tree-sitter-context_en Parser
by Paul Mazaitis 22 Apr '22

22 Apr '22

Hi, everyone! I've been working on an updated tree-sitter parser for the ConTeXt file format. The parser has pretty good support for parsing a ConTeXt .tex file and producing a syntax tree for that file (and, optionally, highlighting). The parser also has support for using appropriate parsers for areas of the document that embed other languages or formats. For example: a tree-sitter parser for Lua code already exists, and this parser can call out to that parser to handle any properly demarcated Lua code (\startluacode ... \stopluacode) present in a ConTeXt document. A full list of supported inclusions (with or without available parsers), along with additional notes, are in the Garden: https://wiki.contextgarden.net/pm39_tree_sitter_parser ...and the repo for the tree-sitter-context_en parser itself is here: https://github.com/pmazaitis/tree-sitter-context_en Tree-sitter parsers support lots of language bindings with which to build tools; I've put together a very badly engineered format-aware spellchecker as a demo (may have trouble with Windows EOL encoding): https://github.com/pmazaitis/contextpyspell-demo Please, please do not use this demo in production. :) A massive caveat regarding OS support: So far this has been all developed and tested under MacOS, and seems to work pretty well in that environment. I've also tested running the parser on Linux (Ubuntu), and that was also fairly straight forward. In either case, Rust and a C compiler are required for directly using the parser (and you'll also need node/npm to rebuild the grammar itself, if you want to make any changes). I have a Windows 10 machine, and the development environment on it is a complete puzzle to me. I am learning, but: running this parser under Windows isn't something I've been able to get working. If you have Windows development experience, I'd be happy for any advice on how to support this software on that platform. A second, massive caveat for Windows support: this parser should be agnostic about how line endings are encoded, and I've done minimal testing, but it should have a lot more. Looking forward: - This parser is...lightly tested. (More testing of more domains would be helpful!) - This tooling should be useful for small utilities: a linter, a formatter, a better spellchecker? - This tooling should be useful for LSP support? Onward! -Paul

Centering figures that extend into the margin
by yann＠yannherklotz.com 20 Apr '22

20 Apr '22

Hi, I've been playing around with 'marginnote' layout similar to tufte's books. The main thing that I can't figure out is how to centre figures that extend into the margin. These should take over the whole page, but the content of the figure should be centred, which is normally the case in normal figures.

Need some hints to fix my standalon installation
by Christoph Hintermüller 20 Apr '22

20 Apr '22

Hi Have updated my standalone installation from one of the 2020 releases to the latest one running ./first-setup.sh --context=latest --modules=all Now i see the strange behavior that fraction in second equation is not typeset instead typesetting math aborts after typesetting the upper part of the fraction. A short example showing this is attached (pdf, tex, and log) Therefore i have the following questions - would it help to sacrifice the updated standalone installation and do a fresh install - What else i would have to check and probably fix to make the math working as expected - any thing else to change -- -- Christoph Hintermüller Dipl.-Ing.

Hi there just a quick question: Is there a command or package to embed the source-file (*.tex) into the resulting pdf-file, just like in LaTeX using package »embedall« <https://mirror.las.iastate.edu/tex-archive/macros/latex/contrib/embedall/em…>? Many thanks and kind regards Heinrich

Hi Pablo Many thanks. That is exactly what I need, ie. to deliver the source code embedded in the PDF. attachment works like a charm Rik pointed me — additionally — into the direction of being PDF/A compliant. PDF/A is possible with setupbackend\setupbackend[format={pdf/a-3a}] but needs fixing with acrobat-preflight to pass validation (in Acrobat and veraPDF).

xmlpos values doubled
by Ben Moon 20 Apr '22

20 Apr '22

Hello All, I'm trying to render a table stored in XML JATS format (https://jats.nlm.nih.gov/archiving/) and eventually want to use the <colgroup> tag to setup column aligning from the @align attribute, e.g., \setupTABLE [column] [\xmlpos{#1}] [align=\xmlatt{#1}{align}] Including \xmlpos{#1} I get double the value returned, i.e.: the first element in colgroup returns 2, the second returns 4 etc. Below is a MWE to show my issue. I show \xmlpos for each <col> tag in <colgroup> above the table, which returns 2, 4, 6, 8 but I expected 1, 2, 3, 4. Am I missing something or is there another way I could do this? ~~~~~~~~~~~~ \startbuffer[table] <table-wrap> <table> <colgroup> <col align="center" /> <col align="right" /> <col /> <col /> </colgroup> <thead> <tr> <th>H1 (centre)</th> <th>H2 (right)</th> <th>H3</th> <th>H4</th> </tr> </thead> <tbody> <tr> <td>A1</td> <td>A2</td> <td>A3</td> <td>A4</td> </tr> <tr> <td>B1</td> <td>B2</td> <td>B3</td> <td>B4</td> </tr> </tbody> </table> </table-wrap> \stopbuffer \startxmlsetups xml:tabletestsetups \xmlsetsetup{#1}{*}{-} % tables \xmlsetsetup{#1}{table-wrap|table}{xml:*} \xmlsetsetup{#1}{thead|tbody|tr|th|td}{xml:table:*} \xmlsetsetup{#1}{colgroup|col}{xml:*} \stopxmlsetups \xmlregistersetup{xml:tabletestsetups} \startxmlsetups xml:table-wrap \startplacetable % \contextversion \par \xmlflush{#1} \stopplacetable \stopxmlsetups \startxmlsetups xml:table \bTABLE \xmlflush{#1} \eTABLE \stopxmlsetups \startxmlsetups xml:colgroup \xmlflush{#1} \stopxmlsetups \startxmlsetups xml:col \xmlpos{#1} \xmlatt{#1}{align}\par \stopxmlsetups \startxmlsetups xml:table:thead \bTABLEhead \xmlflush{#1} \eTABLEhead \stopxmlsetups \startxmlsetups xml:table:tr \bTR \xmlflush{#1} \eTR \stopxmlsetups \startxmlsetups xml:table:th \bTH \xmlflush{#1} \eTH \stopxmlsetups \startxmlsetups xml:table:tbody \bTABLEbody \xmlflush{#1} \eTABLEbody \stopxmlsetups \startxmlsetups xml:table:td \bTC \xmlflush{#1} \eTC \stopxmlsetups \xmlprocessbuffer{main}{table}{} ~~~~~~~~~~~~ All the best, Ben Ben Moon ben(a)themoons.uk

Math functions not typeset inside MetaPost
by śrīrāma 19 Apr '22

19 Apr '22

Hi Hans, [I am sending this again since the previous mails regarding were sent during the weekend]. I am on the most recent upload of LMTX [2022.04.15 20:20]. However, when I try to use math functions inside MetaPost strings, the function is not typeset correctly. Please consider the following MWE: \starttext \startMPcode draw textext("\m{\max_i x_i}"); \stopMPcode \stoptext which produces the output attached here as an image. Instead of the mfunction maxᵢ xᵢ some form of the string mathfunctionhandlelabel is typeset. I tried to inspect \math_function_handle_label [math-ini] and also mp-mlib and mlib-pps but could not figure out what is going wrong. I wonder if there is a backslash missing somewhere. I am a little worried since I use MetaFun in conjunction with maths and could not figure out what the issue is. Please see the original post by Dalyoung here: https://mailman.ntg.nl/pipermail/ntg-context/2022/105462.html Please advise. Thank you, Sreeram

Word wrap of 'part' titles
by Bruce Horrocks 18 Apr '22

18 Apr '22

In the MWE below the 'part' title is centred but on one line only and, because it is a long title, the beginning and end are lost off the sides of the page. If it were a 'chapter' title then I could insert '\\' to cause a line break at that point. However this does not seem to work for 'part'. Is there a way of making 'part' titles wrap the same way that 'chapter' titles do? % ---begin--- \define[2]\placePartTitle{\midaligned{#2}} \definehead [Part] [part] \setuphead[Part] [ placehead=yes, style={\tfd}, command=\placePartTitle, ] \starttext \startPart[title={A very long part title that needs to be wrapped manually}] Some body text \stopPart \stoptext %---end--- — Bruce Horrocks Hampshire, UK

How to create a more human-readable syntax for displaying workbook activities?
by Joel 18 Apr '22

18 Apr '22

I am creating a student workbook. There are ~30 chapters, each containing ~20 activities, called "Activity A", "Activity B", and so on. The `workbook.tex` itself uses a recurse function, so it prints chapter 1-30. The reason I use this, is if I need to do a fast test of the code, I can compile a specific range of chapters, not the whole workbook. \define\activityA{} \define\activityB{} \dostepwiserecurse{1}{30}{1}{ \chapter{\recurselevel} \activityA \activityB } \activityA prints the workbook activity "Activity A". \activityB prints the workbook activity "Activity B". The problem comes in that some activities have varied versions. Just as an example, "Activity C might be a crossword puzzle in some chapters, but a word search in other chapters. My poor solution has been to use registercyclist: \define\altCa{print a crossword} \define[3]\altCb{print a word search} \registercyclelist{activityClist}{\altCa, \altCb{}{}{}, \altCb{}{}{}} \define\activityC{% \usecyclelist{activityClist} } This code works okay, but becomes broken if I try to change the page range in `dostepwiserecurse` when testing my code. The other problem is the syntax is super messy. Within this single line, tones of data is crammed in: \registercyclelist{activityClist}{\altCa, \altCb{}{}{}, \altCb{}{}{}} ...not only is it not easy to read which chapter gets which activity, I also have to fill in the {}{}{} with data, making it more difficult to read. How can I create a much cleaner, human-readable syntax for storing this? Is there some simpler way to tell ConTeXt Chapter 1 gets one variant, Chapter 2, 3, and 4 get another, etc.?

placing (on) layers

TeXworks on Linux
by Willi Egger 16 Apr '22

16 Apr '22

Good evening! Currently I am trying to test different editors on a Linux-box. — Tonight I installed TeXworks. Now I wanted to change the editor to use ConTeXt LMTX. I added in the tab “typesetting" the path to the executables in the TeX tree. Then I added funder editing the processing tools following the Wiki as a programme mtxrun and as parameters —script context $fullname. After restarting the application I get the error: “unknown script ‘mtx-base.lua' or ‘mtx-mtx-base.lua’” My question is, is there a user out there who knows how to fix this? Kind regards Willi

<dc:language> to XMP info?
by Pablo Rodriguez 16 Apr '22

16 Apr '22

Hi Hans, I need to access the document language using Poppler’s GObject introspection. Right now, the only way to do that would be to have <dc:language> (https://raw.githubusercontent.com/adobe/XMP-Toolkit-SDK/main/docs/XMPSpecif…) in the XMP metadata included in the PDF file. Would it be possible to have <dc:language> included in the XMP metadata (besides other DC elements, such as author, title, description or format)? Many thanks for your help, Pablo

new upload
by Hans Hagen 16 Apr '22

Hi, I uploaded a new lmtx. Apart from a experimental intersection feature in the mp library (and metafun, more will be revealed when MS an I are okay with it) there is not that much news. I decided to turn some test code into a mechanism which is illustrated below. Adaptive boxes are hboxes that act a bit like glue which means that when we hook in e.g. a graphic it can be made to adapt. We can add some more methods if needed so maybe you see other usage. The interface is rather lightweight and the overhead is quite resonable. Hans =================== \starttext \startMPdefinitions def TickTock = interim linecap := squared; save p ; path p ; p := fullsquare xysized(AdaptiveWidth,.9(AdaptiveHeight+AdaptiveDepth)) ; fill p withcolor AdaptiveColor ; draw bottomboundary (p enlarged (-AdaptiveThickness) ) withdashes (3*AdaptiveThickness) withpen pencircle scaled AdaptiveThickness withcolor white ; enddef ; \stopMPdefinitions \startsetups adaptive:test \setbox\usedadaptivebox\hbox to \usedadaptivewidth yoffset -.9\usedadaptivedepth \bgroup \hss \startMPcode TickTock ; \stopMPcode \hss \egroup \stopsetups \definecolor[adaptive:tick][.25(blue,green)] \definecolor[adaptive:tock][.75(blue,green)] \defineadaptive [tick] [setups=adaptive:test, color=adaptive:tick, foregroundcolor=white, foregroundstyle=\infofont, strut=yes] \defineadaptive [tock] [tick] [color=adaptive:tock] % with postprocessing \dorecurse{5}{ \dostepwiserecurse{1}{150}{1}{% this~#1.##1 is~#1.##1 test~#1.##1 \ifodd##1\relax \adaptivebox[tick]{\hss tick #1.##1\hss} \else \adaptivebox[tock]{\hss tock #1.##1\hss} \fi } \blank } \page % without postprocessing \dorecurse{5}{ \dostepwiserecurse{1}{150}{1}{% this~#1.##1 is~#1.##1 test~#1.##1 {\showboxes\adaptivebox[strut=yes,foregroundcolor=darkred]{\hss test #1.##1\hss}} } \blank } \page % with images % a weird one \setupexternalfigures [location={default,global}] \startsetups adaptive:test \setbox\usedadaptivebox\hbox to \usedadaptivewidth yoffset -\usedadaptivedepth \bgroup \externalfigure [cow.pdf] [width=\usedadaptivewidth, height=\dimexpr\usedadaptiveheight+\usedadaptivedepth\relax]% \egroup \stopsetups \dorecurse{5}{ \dostepwiserecurse{1}{150}{1}{% this~#1.##1 is~#1.##1 test~#1.##1 {\adaptivebox[strut=yes,setups=adaptive:test]{}} } \blank } \stoptext It actually uses an already present for a while low level engine feature that we introduced as part of the math processing update: \dorecurse {1000} {test \uleaders\ruledhbox{\hss#1\hss}\hskip2em minus 1em\ } Next on the todo is to move some experimental graphic trickery related to math (matrices) into the core but the interfacing needs some thought.

> You can use different alignment settings to move the bullet points to > the right side of your lists. Thank you Wolfgang, this is exactly what I need. One more question: I am typesetting those questions in lua, because lua vectors were more convenient for reading the whole but I am not sure how should I pass the righttoleft option. I read the cld manual and my guess is I should use function() but looks like I lack some understanding of context proceeding. This is what I did so far \startluacode userdata = userdata or {} function ListeAleatoireGauche(t) context.startitemize {"8","packed","random"} for k=1,#t do context.startitem() context.lefttoright(t[k]) context.stopitem() end context.stopitemize() end function ListeAleatoireDroite(t) context.startitemize {"8","packed","random"} for k=1,#t do context.startitem() context(t[k]) context.stopitem() end context.stopitemize() end function QCMAssociatif(t,u) context.startxtable {"frame=no","columndistance=3cm"} context.startxrow() context.startxcell() ListeAleatoireGauche(t) context.stopxcell() context.startxcell() ListeAleatoireDroite(u) context.stopxcell() context.stopxrow() context.stopxtable() end \stopluacode \starttext \startluacode Author = {"Nietzsche","God"} Quote = {"God is dead","Nietzsche is Dead"} QCMAssociatif (Author,Quote) \stoptext Damien Thiriet

fatal error in LMTX

Hi Hans, I have a minimal sample that triggers a fatal error in ConTeXt LMTX (current latest from 2022.04.11 19:27): \starttext \startfrontmatter \input zapf \stoptext This gives the following error message: mkiv lua stats > runtime: 0.386 seconds, 1 processed pages, 1 shipped pages, 2.592 pages/second mtx-context | fatal error: return code: 1 The one above is a stupid sample. But it took me about two hours to discover what was triggering the fatal error message. I wonder whether it would be possible that ConTeXt or LuaMeTaTeX could be more verbose about an opened environment that isn’t closed. Many thanks for your help and your excellent work, Pablo

Dear All, Is there a straightforward way of setting up the itemize command such that every first letter is capitalized, regardless of whether I do so in the source file? Also, is there a way to insert a comma at the end of each item except for the last, and then a full stop at the end of the last item like follows? - First item, - Second item, - Third item, - Last item. Thanks in advance. Amine

Thank you for all your answers. I will have a deeper look at them. My first comments: > If you are certain that the there will be no > multi-line item Unfortunately there are often some. History teachers are not known for loving short texts, at least in France. > Using the “columns" feature is one way to go Might be, but I do not always give the same number of answers on both columns Something I forgot to put in my MWE is that I randomize both lists. Messing the answers is a good way to prevent pupils from cheating, especially with long answers.. That makes a four columns table more cumbersome, so I believe. Damien

I am used to giving associative questions to my pupils, something like * connect the author with its ideas Friedrich Nietzsche * * "God is dead" Woody Allen * * "Nietzsche is dead, God is dead and I don't feel so good" God * * "Nietzsche is dead" I design it as a two-cells xtable with itemized lists inside. How can I have the item mark on the right side? \starttext \startitemize [8] \startitem Nietzsche \stopitem \startitem Allen \stopitem \startitem God \stopitem \stopitemize \stoptext Greetings, Damien Thiriet

Regular online meet-up
by Henning Hraban Ramm 11 Apr '22

11 Apr '22

You’re invited to join next Tuesday, February 8th, 15:00 CET (UTC+1) at https://lecture.senfcall.de/hen-rbr-rku-oke ConTeXt users of all levels are welcome! Hans offered to give a Q&A session again – please announce subjects you’d like to discuss ASAP, so that he can prepare. Regarding the date: Denis, who originally suggested Tuesday afternoon, can’t take part due to other obligations. I could also offer Wednesday or Thursday. We could also change the weekday every time, but that might be confusing. I would keep the European afternoon time, since that makes participation possible for people from America and Asia. What do you think? Vote here: https://nuudel.digitalcourage.de/tB1MHH4jx6M5uwPg (Same blurb as last time:) [Howto] * No special software installation required; most modern browsers should work (WebRTC required). * Open the above URL, accept the privacy statement, * enter your name, * click "join" (or "start" if you’re the first), * click "with microphone", allow your browser to access it, check the audio. * Your microphone is muted if you join. Activate microphone and/or camera with the buttons at the bottom. * Minimize the default presentation with the "screen" button, bottom right. * If you’d like to share your screen or upload a file, you can make yourself the presenter: Click on your user name, change the setting, then you’ll see the "screen sharing" button beside the camera button; also there’s now "manage presentations" behind the "plus" button. Beware there is only one presenter, so don’t kill someone else’s presentation. [Technical hints] * Sound is usually better if you use a headset (less noise for everyone). * Connection problems are mostly due to low bandwidth or high latency on your side, e.g. with mobile connections. * If audio/video doesn’t work for you, you can still use the text chat. * Screen sharing needs a lot of bandwidth. * You can also join with a regular telephone (audio only, of course), call +49-6151-86275-22 (German landline); then you must enter a PIN that changes every time – if you need it, ask me for it via email. Mute/unmute your microphone with "0". [Netiquette] * Please use a name that we recognize from here. Some feel uncomfortable with anonymous lurkers. * Mute your microphone while you’re not talking. * It’s nice to show your face at least when you join. * If there are connection problems, stop camera sharing. * The room is set to “everyone’s a moderator“, I trust you... See you, Hraban

two requests for ConTeXt
by Pablo Rodriguez 09 Apr '22

09 Apr '22

Hi Hans, I have a couple of suggestions to be added to a not so distant release The first one is to allow that ConTeXt LMTX also downloads the available modules. The second feature would be the addition of an "emoji" range for font fallbacks. Many thanks for your help, Pablo

Spellchecking for ConTeXt user on a Windows platform
by A A 02 Apr '22

02 Apr '22

Dear All, I'm currently using ConTeXt on a windows machine. I'd like to incorporate some sort of automated spell-checking in my workflow. I've seen that there are two options: 1. spell check the .tex source file 2. spell check the resulting pdf For the first option many resources online seem to suggest using *aspell. aspell* is however not maintained for windows and therefore hopelessly out of date. Furthermore many resources online seem to suggest skipping TeX and LaTeX control sequences does not always succeed. So I can only imagine how poorly it deals with ConTeXt control sequences. The second option as shown on this StackExchange <https://tex.stackexchange.com/questions/42843/is-there-a-spell-check-packag…> post suggests using *\loadspellchecklist. *However, on of the arguments to this command includes a text file listing - and brace yourself - *all of the correctly spelled words*. I find this both an amusing and tragic proposition, since I basically need to spellcheck based on *every word in a given language.* What options are out there for someone who would like to do serious spellchecking using ConTeXt on Windows platform, using Powershell as my command line? Regards, Amine

mkiv
by Hans Hagen 02 Apr '22

02 Apr '22

Hi, Normally when we're in the 2022 TeXlive code freeze period, there is a snapshot release but because there hasn't been that many changes, maybe a few patches, in MKIV there is no real snapshot this year. But for the sake of consistency we can consider today's version that snapshot. It basically means that MKIV has been frozen and is even more frozen now. All new stuff goes in MKXL (aka LMTX) and I suppose that next year we let that end up in TeXlive alongside frozen MKII and MKIV. Of course bugs will be fixed as usual. So, today is the day we kind of formally freeze MKIV.

new upload / more math
by Hans Hagen 01 Apr '22

01 Apr '22

Hi, As most of you know by now, Mikael and I are working on a math support upgrade. In order to let users keep up we uploaded a new version. We have been revisioning some of the more obscure constructs where we have no clue of usage, like pmod, bmod, bordermatrix etc, commands that we took (and reimplemented) decades ago from plain TeX or AMS TeX, assuming that these are standards. In this release, encouraged by the positive response we received from users regarding the new simplealignment construction, and in particular regarding the self-explaining sesac, we have decided to introduced some new constructs. First out is \startformula \startxıɹʇɐɯ \NC a_1 \NC b_1 \NC c_1 \NR \NC a_2 \NC b_2 \NC c_2 \NR \NC a_3 \NC b_3 \NC c_3 \NR \stopxıɹʇɐɯ \stopformula for rotation matrices. This was demanded for some advanced math courses that Mikael teaches. It might inspire users to come up with demands that suits their own obscure but nevertheless interesting math. At some point we realized that, with (also) scientific publishers (of math journals) moving to MS Word and Indesign, we operate in a rather peculiar niche and the fact that we use an upgraded and more granular math engine, made us wonder how to communicate all these new features and standards that we set. It is for that reason that from now on we will operate under the CMS umbrella. That abbreviation stands for ConTeXt Math Society. It has no funny swirly TeX logo which itself is a statement: in Unicode math script and calligraphic alphabets are so messed up that it is impossible to have a reliable and predictable rendering. We go for Dutch and Swedish simplicity in the spirit of W.N. Lansburgh: back to the times before TeX was written (1964). There will be no limits and boundaries set. (Talking math limits and boundaries: these can already go everywhere anyway, as can fences.) So, when we mention CMS, we mean serious math business, but kindergarten math is also embraced! There are no consequences for users: ConTeXt users with a proven math track record are automatically a member, but we are not too picky, everyone is welcome. We don't have honorary members but Taco (the first ConTeXt math user) and Aditya (the most experienced one) might consider themselves as such. Mikael Sundqvist is the chairman, which is a livelong appointment. (A nice side effect is that with Arthur living in Sweden too, that gives us a very strong position in the TeX landscape there.) So, today's upload is sort of special: welcome CMS (ConTeXt Math Shines), goodbye AMS (American Math Second). Of course we're open for suggestions and it being an open society all voices will be heard, but only proper (retro) math cf Lansburgh will be honored. Of course we only listen to ConTeXt users and, as that package is not supposed to be used for serious math, we don't bother about the few publishers left that still do math. Are we done? Not yet. We're in the middle of (colorful and graphic) alignment ornaments and after that we're going to expand and improve multi-line display formulas and equation numbering. It will be no coincidence that the cover of Landburghs book about math typesetting has a prominent 'AWE' embedded in a logo with a lion on top: we hope all users are in awe about what the TeX lion can do.

Full-page Figure?
by Michael Urban 31 Mar '22

31 Mar '22

I want to have a float (illustration for fiction, with caption) that takes up just one page, irrespective of the size of the image in the figure. This can be done with a \startmakeup, but makeup pages do not float, as near as I can tell; they interrupt the text (leaving a partly blank page); and of course they will not include headers and footers. And a float with [page] will start the figure on a new page as desired, but if the image is too small, other text will end up on the page, which is not the desired result. I want to vertically (and horizontally) center the figure on the page, with no other content but glue, in the main text block. Headers and footers should appear as normal. Is there a simple way to accomplish this? Mike

Breaking url into multiple lines results in broken link in rendered PDF
by A A 31 Mar '22

31 Mar '22

I would like to be able to break up URLs into multiple lines in my bibliography source file and still get the link to work. Here's what I have so far: *\setupinteraction [state=start]\starttext\useURL [myUrl] [ "https://www.g <https://www.g> oogle.com <http://oogle.com>" ]\goto{link}[url(myUrl)]\stoptext* Unfortunately the link does not work. When I *don't* split the URL into multiple lines, the link works again. In reality my link is very long and forces uncomfortable line continuation in my `vim` editor. How can I break up long URLs in my source `.tex` file and still get the link to work in the resulting pdf? [1]: https://tex.stackexchange.com/questions/638541/line-continuation-in-bib-fil…

Typesetting unicode characters
by Thangalin 31 Mar '22

31 Mar '22

Hi list, An XML document includes the 👍 emoji, as shown in the following snippet: <html> <head><meta charset="utf8"/></head> <body> <div class="bubblerx"> <p>Thumbs up emoji: &#55357;&#56397;</p> </div> </body </html> The document is typeset using ConTeXt, but the thumbs up emoji isn't in the PDF. Neither Noto Emoji nor Open Sans Emoji fonts will render. Does anyone have a minimal example that shows how to typeset such escaped entities? When the emoji is added directly to a document, it works fine: \definefont [TextFontEmoji] [opensansemoji] \starttext \TextFontEmoji{Thumbs up emoji: 👍} \stoptext Is there something special that needs to be set for ConTeXt to interpret the escaped unicode values as an emoji? Thank you!

Xml - Lua - context
by Thomas A. Schmitz 30 Mar '22

30 Mar '22

And here comes question 2, a very basic one: on A4 landscape pages, I want to place two images next to each other (like the spread pages of a book). What would be the preferred way of the really competent users to do this, again keeping in mind that I want to loop over page numbers in a pdf file and thus am coding in Lua. So far, I have tried or thought about: 1. Embedded xtable This is what I’m using now, an xtable of two columns for every A4 page. It works, but I wonder if it’s a good method. 2. combinations This appeared to be the most natural approach (because it’s what combinations are for), but I ran into expansion problems, added a few “function () end” in my code, but couldn’t make it compile. Combinations, combined with framed and externalfigure, are difficult to write in Lua - or am I too stupid to find the winning combination (sorry for the puns). 3. columns Again, this would seen like a natural approach, having every A4 page set up as two columns, but maybe that’s overkill? I’d be curious to know what you think! All best Thomas

Xml - lua - context
by Thomas A. Schmitz 28 Mar '22

28 Mar '22

Dear all, For a small project, I have two questions (without MWE…) on processing xml via Lua and context. I’ll write two messages so eager volunteers can reply more easily! So question one: given an xml structure like this <section> <sectiontitle> Introduction: the <em>Iliad</em> </sectiontitle> <sectionlist> Introduction: the <em>Iliad</em> </sectionlist> </section> I want to typeset the section title with some added information. Since I’m processing in a loop, I thought this would be easier in Lua, so I have something like this: local i = 0 local sessions = { “April 2”, “April 9”, “April 16” } -- etc. function xml.functions.section(t) i = i + 1 local raw_section = xml.text (t, "/sectiontitle") local section_head = i .. ". session, " .. sessions [i] .. ": " .. raw_section context.startsection { title=section_head } lxml.flush (t) context.stopsection () end However, this means that the section_head is serialized as a string and not processed according to the xml setups, so I have “the <em>Iliad</em>” in my typeset document. How can this be avoided? How can I have the <em>...</em> processed instead of serialized in the section title? Thanks for looking at my code! Thomas

Line numbering inside display math with mathalign and splitformula
by śrīrāma 28 Mar '22

28 Mar '22

Hi everyone, I have a document with lots of maths. I am using \start...\stoplinenumbering to place line numbers in the inner margins with \setuplinenumbering [location=inner, style=\ttx] The weird thing is I have many display math blocks that break across page(s) using \start...\stopsplitformula with \start...\stopmathalignment. Curiously, the line numbering does not appear in these splitformula blocks alone. (It works for \start...\stopformula) blocks[*]. Below is a MWE: %%% start example \starttext \startlinenumbering \input knuth \startformula\startmathalignment \NC {\mathcal H}_0 \NC : \text { the null hypothesis } \NR \NC {\mathcal H}_1 \NC : \text { the alternate hypothesis } \NR \stopmathalignment \stopformula \startsplitformula\startmathalignment \NC t \NC = f_t(x) \NR \NC m_t \NC = f_m(x) \NR \stopmathalignment\stopsplitformula \stoplinenumbering \stoptext %%% stop example Further, [*]when \start...\stopmathalignment is used, only one (vertically centered) line number appears for the entire block. Is there a way to have the 'usual' line numbering inside the math blocks also? It is not a big problem as such: I can do without it since important equations are numbered anyway in the document (and I can use that to refer to them) but I was just curious if it is possible and/or I have missed something. Many thanks, Sreeram

mathcal generates error in ConTeXt

Dear All, I am using pandoc to covert a file called test.tex from LaTeX to ConTeXt.

zint module on LMTX
by Pablo Rodriguez 25 Mar '22

25 Mar '22

Dear list, using latest LMTX and following the steps from https://wiki.contextgarden.net/Barcodes#Zint_module, I’m afraid I don’t get any barcode either in Linux or Windows. Minimal sample: \starttext \usemodule[zint] \barcode[alternative=isbnx, text=9783865419026, width=4cm] \stoptext Error message is rather weird on Linux: optional > using library '/home/ousia/context/tex/texmf-linux- 64/bin/lib/luametatex/zint/libzint.so' zint > unknown barcode alternative 'isbnx' zint > zint > valid barcode alternatives: zint > [...] zint > isbn zint > isbnx [...] It seems that a valid barcode alternative ends up being unknown to the library. What am I missing here? Many thanks for your help, Pablo

redefining xmlsetups inside a XML document
by mf 24 Mar '22

24 Mar '22

Hello, I'm trying to add new templates (xmlsetups) from the XML document itself. See the attached MWE. - the XML document is a simple XHTML file - in the "head" element there's a "script" element with the "type" attribute set to "text/vnd.context", whose contents are then passed to \xmlcontext - the "body" element has a "data-xmlsetups" attribute whose value should tell which xmlsetups is to be applied on the body contents (it's defined in the "script" element above) If it worked, the resulting PDF should show the body element, followed by a "Hello world!" paragraph written in red. But it does not work, because there's something I'm missing in the redefinition and application of xmlsetups. To try the MWE, type: context --environment=nested-xmlsetup.tex --forcexml nested-xmlsetup.xhtml Massi

Make footnote/endnote number not superscript?
by Bruce Horrocks 21 Mar '22

21 Mar '22

I'm editing a book that will be printed, however the authors have included URLs which will no doubt suffer from "bit rot" in no time at all. I think it will make the main text cleaner if I use endnotes rather than include the URL in-line in the text or as a (distracting) footnote. So when the author writes "See my video at <long Youtube URL>" I will print "See my video at link 1". At the back of the book, in an appendix somewhere, I then use \placenotes to display a table of the actual URLs for any readers that want to type them in. I want the "link 1" bit to be normal text rather than superscript so it's more visible. Using the \setupnote[textstyle=...] command I can change the style of the number but not the superscript placing. Is there a way to remove the superscript placing, please? Alternative solutions welcome: the URLs printed in the book will be mirrored on a web page associated with the book for as long as possible so that content that vanishes over time can be replaced with Internet Archive links as they are discovered. However the order of the book isn't finalised yet so I'd like the numbering to be sequential regardless of whether I move a chapter around later on. This is partly the reason for using \endnote because I can use a reference elsewhere in the text if necessary. Thanks in advance. — Bruce Horrocks Hampshire, UK

Good evening! I have a dictionary where I would like to include thumb-pictures in the margin. — When I use the attached code with a single \startchapter...\stopchapter, it works. However if I add another \startchapter…\stopchapter before loading the setups for the thumb-picture metafun throws an error about not having complete information for performing a transformation. I am currently using the before last version of LMTX-ConTeXT (January 21st 2022). Could someone try to compile? Thanks, kind regards Willi

\setupheadertexts for chapters with different authors

I thought this should work, since \structurelistuservariable{author} works fine to call the author name into the TOC, but the same does not work for header texts it seems: \setupheadertexts [{\hfill\getmarking[\structurelistuservariable{author}]\hfill}][] [{\hfill\documentvariable{metadata:title}\hfill}][] But it doesn't. What am I doing wrong? Julian

Tex capacity exceeded...

Thanks Hans, and Rik. Perhaps I need to take a much closer look at this file to see if I have created some grouping issues. The removal of the .tuc file is a very handy tip that I hadn't thought of, and I assume it is associated with the way Hans put it, namely, 'looks like you load the same file...' Julian

TeX capacity exceeded.... but....
by jbf 17 Mar '22

17 Mar '22

I'd like to understand what is happening in this particular instance: While playing with a suggestion to a recent request (re \currentlistentrynumber etc.) I suddenly got a compiling error: TeX capacity exceeded, sorry [file=2000]. I returned everything to how it was before I was trying out those suggestions, but still got the error, so I began the \stopdocument routine fairly early in the document... same problem still. Then I brought the \stopdocument well forward, immediately after the standard makeup pages and the document compiled. When I removed \stopdocument, the entire document compiled as it should. So the basic question is: what can be causing the error message? This has happened to me on two occasions with this document - it occurred once before I had even begun experimenting with the \currentlistentry options, so I do not think that the problem lies there. And when it occurred that time, I again solved it with \stopdocument routine, but further into the document. And similarly, once it compiled that far and I removed it, the whole document compiled once more. If it is too complicated an explanation for an email response, maybe just point me to a document that explains the issue. Julian

Calling in chapter number in list={}
by jbf 17 Mar '22

17 Mar '22

I wonder if there is a way I can call in the chapter number in the TOC, although that number is not used for chapters as such. I know the chapter number is 'remembered' anyway, so there is probably a way I can call it in just for the TOC. The context for this question is the layout for book which comprises individual contributions, and each contribution has its own author/copyright (hence the individual chapters bear a title without a number, but the editor who has compiled these wants them numbered in the TOC). I currently call the author name in the TOC with: \define[1]\SectionTocEntry{% \leftaligned{#1}\par% title. \leftaligned is needed \hskip1cm\relax\doifnot{\structurelistuservariable{author}}{}{\structurelistuservariable{author}}% } \setuphead[chapter] of course includes number=no. \setuplist[chapter] is currently set as: [label=yes,distance=1.2cm,style=normal,before=\blank,after=\blank,textstyle=normal,alternative=c,textcommand=\SectionTocEntry,] And for the moment I simply use, as part of the \startchapter[] description: list={1. This is the rather long title of the first chapter, with the number included at the beginning}. While that gives me the number of the chapter, it does not give me correct indentation when the chapter title runs to more than one line. What I would prefer to do is to be able to call the chapter number automatically with placing 1., 2., etc. in list={}. Julian

Force a hyphenation

Hi, at the moment I am dealing with a German text. Although I have \mainlanguage[de] in the preamble the word 'des Eiweißes' is hyphenated as 'des Eiwei-ßes'. Of course this should be 'des Eiweis-ses'. How can I make sure that ConTeXt is hyphenating this corerctly? Kind regards Willi

new upload
by Hans Hagen 16 Mar '22

16 Mar '22

Hi, It has been a while since there was an updaste but there it is. The most significant 'changes' are: - more automatic adaption to double sided page properties in metafun (lmtx) ... blame sreeram and me for messing up - more extensibve support for indic fonts which sreeram has documented on the wiki (fonts, translutaration etc) and - improved math rendering to be documented by by mikael in an upcoming manual ... it tooks a couple of months so it is supposed to have some impact. before we move on the the structural compoments and see what can be done beter there, we decided to release the first stage that deals with: = fixing font properties; we don't expect fonts to be improved so that's the route we follow = extensive inter atom spacing (we have many more math classes, some in the engine, some in context) and everything can be controlled (the old pairwise spacing primitives have been replaced by a more general mechanism, including support for fast setup of categories and inhertance from other classes) = idem for inter class penalties, including granular control over line breaks using a system of (in/de)creasing penalties = auto-fenced inline material across lines and linebreaks in molecules (read: complex atoms) = taking stretch and shrink in encapsulated atoms into account in linbreaks (using some new box related mechanism that is also available in text and will be explained later) = spacing at the edges that should not be there but always was there as side effect of the engine is now removed; as with other new features this can be controlled (we have rulesets for atoms to which we can add more in the future) = more detailed control over (skewed) fractions, (flattened) accents, (sized) fences, radicals ... there was already a lot there but it now combines with mentioned spacing (when relevant the context macros have been adapted to control this which is a bit cleaner) = we have a new built in muskip (tiny) but as we have an inheritance system as well as binding to variables one can set up extensive spacing models register and constant binding; the currently set values are based on math typesetting references; in the future we might have additional ones = although we did handle primes already rather transparent in mkiv / lmtx, inconsistency in fonts made us decide to make primes first class properties of atoms and molecules which means that we now have: pre super/subscripts, post super/subscripts and primes; this permits nicer anchoring under parameter control = there are more font parameters to control matters (they are not in open type but we sort of assume they are); the options that we had to control how the engine deals with fonts are now driving the process (without them being set not much is applied) and we basically assume open type fonts (where one can enable engine options for those kind of fonts but also for traditional); some experimental options for testing are gone = in the process tracing for what is done in math by the engine has been extended (mostly for ourselves) = instead of auto patching math fonts most is now under control of the goodie files; user can (as usual) make their own, but also ask Mikael to add missing bits and pieces (wrt dimensions) = most known math fonts are dealt with but there are a few exceptions: we no longer consider asana to be useful (it doesn't pass our qa and needs too much patching); erewhon is also troublesome (dimensions, missing shaped) as is concrete (idem) so we decided not to waste too much time on them now = we probably need to freeze math fonts in the distribution and only update when we know what has been changed = we got rid of quite some artifacts that normally go unnoticed (like tiny added spaces that result from always applied spacing even if not needed and/or to compensate for glyph features like too much or little side bearing): by fixing inconsistencies in fonts we could get rid of all and therefore inter atom spacing is what does the job; once you know it, you see it and there is no going back = because we zoom in we notice these things but much went unnoticed (or was just accepted) for years; it means that we think some of the things we did qualify as math micro typography (like it or not) and it does mean that documents can render differently (unlikely for display, propably also for inline unless you have plenty of math in a paragraph) == our objective has been to make it easier for users and to get rid of explicit spacing; for that we also introduced commands for differentials (that have their own class), imaginary numbers (also have their class) and we added exponential as class; fwiw, digits and factorial are classes too so again spacing has been optimized for them = whatever i forgot in the meantime mikael will add to this list There is a rough description in the 'ontarget' document. We hope you enjoy it, at least we did (and so, as we're not finished yet).

Hi! I tried to compile the MetaFun manual from /doc/context/sources/general/manuals/metafun and ran into a few issues. I don't know if that's expected or if it's supposed to work on a current LMTX. Attached are the first two issues. It takes a while to boil it down to MWEs. Let me know if I should report the other errors, too. I'm not using the failing bits myself, so I don't need fix for that. Motivation is to help find issues with the current release. Marco

help with facing page image
by jbf 11 Mar '22

11 Mar '22

I wonder if someone can help me untangle the current little mess I seem to be creating! Author wants an image on facing page to each of 10 chapters in the bodypart of the document. Assume that everything else is working properly for this document (double-sided etc.), but other than before chapter 1, I can't seem to get my facing page image to appear where it should! A question along these lines (but not quite the same) was asked back in 2019, so I started with what seemed to me to be the simplest response to this question. Here is what I have to get the image before Chapter 1 in bodymatter: \startbodymatter \definelayer[mylayer] % name of the layer [x=0mm, y=0mm, % from upper left corner of paper width=\paperwidth,height=\paperheight] % let the layer cover the full paper \setlayer[mylayer] [hoffset=2.5cm, voffset=3cm] {\externalfigure[Chapter1.jpg][width=.9\textwidth]} \doifoddpageelse {} {\pushbackground[page] \setupbackgrounds[page]%[background=color,backgroundcolor=red] [background=mylayer] \page[empty] \popbackground} \startchapter[title={Prelude}] etc..... This correctly places the Chapter1.jpg on the facing page to Chapter 1. My problem comes with Chapter 2, since Chapter 1 finishes on an even page, and this means I would need a blank odd page to follow that so that Chapter2.jpg (a different image to the first) can be on the verso of that and the Chapter itself would then start on the odd page facing that. I think the \doiffoddpageelse command above is only meant to work when a chapter ends on an odd, not an even page, but I do not know what alternative command to give. Repeating the above set of commands prior to \startchapter for chapter 2 places the image, naturally enough, behind the last page of text for Chapter 1, which is unacceptable, so I thought I could simply add a blank page or two after the chapter and it would all fall into place. I tried various ways of doing that (e.g. \page[+2], or using makeup pages), and while I can add pages that way, I can't get the image to appear. No doubt the solution is simple enough. It might also lie in the \setuphead[chapter] arrangement too. I've tried page=yes there, but to no avail. I also tried \ startsetups[chapter:before] with the pushbackground etc command and added that in with before=\directsetup{chapter:before} as suggested in the wiki, but couldn't get that to work either. By that stage I was so tangled up in the problem I may not have been able to think straight :-). Somehow, though, I think most of the elements are there. Any help would be appreciated. Julian

interlinespacing in margin notes – solved
by Henning Hraban Ramm 10 Mar '22

10 Mar '22

Hi all, esp. Hans and Massimiliano, yesterday in the online meeting we discussed (again) my margin notes problems. A quite minimal setup is shown below. My remaining problem was that the footnotes always used the interlinespacing (baseskip) of the main text. Finally I found the reason in my typescript file: \definefontfeature[default][dimensions=strut] (I guess I tried to solve the irregular line spacing with that setting.) Thank you for your patience! Now I need to adjust the linespacing and page breaking in all other parts of my current book...

"Flushbottom" / \setupalign[line] in LMTX
by denis.maier＠unibe.ch 09 Mar '22

09 Mar '22

Hi everyone, a quick follow-up to todays monthly meeting: A couple of months ago I ran into issues getting "flushbottom" typesetting right. See: Today, some of these issues seem to have been fixed.

Few quick questions
by Christoph Hintermüller 09 Mar '22

09 Mar '22

Hi I'm still stuck with also providing my lecture notes as epub in addtion to its PDF version. The last year, when I tried figure what is wrong, Hans indicated a tool, a program, which allows to verify that that all start* stop* tag pairs are symmetric and placed in correct order. I just cant remember how it is called. Can anybody help here? Second are there any limits in how large files exproted to XML, XHTML etc can be. Does the exporter automatically try to split huge documents into multiple exported documents when some size is exceeded or was or is such a feature allways experiemental up to mkIV and what could break proper slitting which contexts, commands should not be active to avoid breakage. My current setup is neither a fresh install of latest standalone nor texlive installation. This task is still pending. I just have done some partial update mixing 2020 Texlife with 2021 standlalone by calling update.sh. So the aborting of the export in the middle of a hundred pages long document with plenty of floats and the heavy use of Aditya's t-vim package might additionally be worsened by some inconsistencies of my currently not clean installation. But to rule out or properly tackle down I think I believe knowing about possible Limitations of exporter in mkIV if any to be saving a lot of time The abort in xml export also occurs when i inline all files exempt t- vim code snippets, png or svg files replacing meta post images into one huge document removing any \input commands. Therefore i want to check first on the inlined document if there would by any asymetric start* stop* before persuing further.

APS bib: literals and small error in "pages" field
by Jack Hill 07 Mar '22

07 Mar '22

Hi, Two things here: 1. There is an extra . on the end of lines 732 and 734 of publ-imp-aps.mkvi which causes references to be rendered like "p.. 417" and "pp.. 417--418". 2. Suppose I have a literal such as @literal{company, text = {Company Name (n.d.) {\it Webpage name}. Retrieved 22 February, 2022, from https://www.example.com} } how can I cite this without the (company) appearing in the bibliography list? For reference I'm using \usebtxdefinitions[aps] Jack

Makeup on same page as main content
by mastermind_ x 05 Mar '22

05 Mar '22

Hi all, I would like to create a makeup environment that will contain author, university logo and date and other information that doesn’t occupy its own page that I can define in an environment file and reuse. The logo and date should occupy the margins at the top at the left and right respectively. Then there will be course information on the left and a framed assignment box on the right (as it will have special fonts). Much like the title of a latex article class. It should look something like this: [logo] [date] --------------------------------------------- [course]: [Code] [assignment] [name] [ ] [class] [ 1 ] ---------------------------------------------- body Any pointers on how I can achieve this?

LMTX | (.\) at end of line causes fatal error
by Richard Mahoney 05 Mar '22

05 Mar '22

Something I've noticed for a little while now, although it may be long standing, I'm not sure. If one ends some of the lines in the input files with a full stop (.) and a back slash (\) then LMTX will fail to compile with a fatal error. The only way to recover is to go through each of the files and ensure that no line ends with (.\). Is this a bug?

mathalignment not working (? again ?)
by śrīrāma 02 Mar '22

02 Mar '22

Hi, While setting some rather large set of equations in a document I could not achieve proper alignment of columns in mathalignment. Below is a demonstrative example: \starttext \placeformula \startformula \startmathalignment[n=7,align={right,left,right,left,right,left,right}] \NC x_1 \NC + \NC x_2 \NC + \NC 6x_3 \NC = \NC 170, \NR \NC 3x_1 \NC - \NC 110x_2 \NC - \NC x_3 \NC = \NC 4, \NR \NC 14x_1 \NC + \NC 13x_2 \NC + \NC 10x_3 \NC = \NC 25. \NR \stopmathalignment \stopformula \startformula \startmathalignment[align={left,right}] \NC \sin^2 x + \cos^2 x \NC = 1 \NR \NC e^{iπ} \NC = -1 \NR \stopmathalignment \stopformula \stoptext The first example is from the wiki and the second one is just something I wrote as an example. Compiling the above, I see that the equations are not aligned as requested. There was an earlier discussion on this here: https://www.mail-archive.com/ntg-context@ntg.nl/msg97115.html However, I have: mtx-context | current version: 2022.01.21 20:13 where I have verified that the fix therein is present (in math-ali.mkxl). Have I gone wrong somewhere ? Thanks, Sreeram

Re: [NTG-context] Problems with itemize with several columns
by Xavier B. 25 Feb '22

25 Feb '22

It seems that putting \column before itemize of 'c', forces 'c' together with this content. Repeating this step produces what I want: \startexercici[exercici:operacions-amb-fraccions-2]{multiplicació i divisió} Opereu: \startitemize[a, columns, three] \item \startformula 3 \cdot \frac{5}{3} \stopformula \item \startformula \frac{3}{4} \cdot \frac{2}{5} \stopformula \column \item \startformula \frac{1}{3} \cdot \frac{3}{4} \div \frac{1}{5} \stopformula \item \startformula 5 \div \frac{7}{10} \cdot 7 \div \frac{2}{5} \stopformula \column \item \startformula \frac{1}{2} \cdot \frac{1}{2} \stopformula \item \startformula \frac{3}{2} \div \frac{2}{3} \div \frac{5}{4} \stopformula \column \item \startformula \frac{2}{3} \colon \frac{2}{5} \stopformula \item \startformula \frac{3}{4} \colon \frac{1}{2} \cdot 6 \stopformula \item \startformula \frac{2}{3} \colon \frac{3}{4} \cdot \frac{1}{2} \stopformula \stopitemize \stopexercici @fv leung said I have to replace frac for dfrac, but it mess up the following content in my book.

Item (c) will need the same amount of space, shown by the red line.
