Re: which parameter is for adjust the distance between items in a list?
by hf＠hongfeng.ch 25 Apr '24

25 Apr '24

thank you. just tried, not worked out yet. Here it is my text: ``` setuplist[height=0] \startitemize[n] \item It's impossible --- don't waste my time. \item It's possible, but not worth doing. \item I said it was a good ideal all along. \stopitemize ``` Now the distance between the items is equal to the blank space between paragraphs. I want to reduce it equal to the distance between the lines of a paragraph.

what are the interaction between \showframe and \realpageno in \startuseMPgraphic ?

I can not figure out why this progress bar only works when \showframe is activated. When you comment on \showframe, it's as if \realpageno is at zero.

Why don't footnotes appear in floats or figures?
by Joel 24 Apr '24

24 Apr '24

I'm three days out from sending my work to an editor, and found some serious problem: many footnotes just aren't rendering. I have a history text that uses ConTeXt-SBL for the citations, as such, it has lots of footnotes. Sometimes the footnotes are just in the main text, but sometimes also in figure captions, inside floats, inside tables that are inside floats, inside tabulations inside floats, etc. What I find alarming is it is frequently not rendering all of the footnote messages at the bottom of the page. The actual footnote number within the body is rendered, but no number is listed in at the bottom of the page. So I might see a list of footnotes, for instance, on page 1, I only get footnotes 1, 2, 3, 5, and 6, but 4 was mysteriously skipped. ---------------1 message2 message3 message5 message6 message After a lot of trial-and-error and checking logs and checking my BibTeX files for errors, running everything through BibTex Tidy, etc., and failures to make a minimum working example, I found a single pattern: If the footnote marker appears on the SAME page as the footnote text, it has no problem rendering the footnote. But, if ConTeXt decides to move a float a page or two later on--as it frequently seems to do---such that the footnote marker and footnote text at bottom of page should be on DIFFERENT pages, the footnote message at the bottom of the page won't render. I've seen some 2+ year old mailing list posts suggesting ConTeXt might have issues with footnotes; they appear to be similar to my issue--is that still a problem? Is there a fix or workaround? Old fixes I could finding in the mailing list don't seem to work with current versions of ConTeXt anymore. --Joel

Why are ConTeXt-SBL endnotes empty?
by Joel 22 Apr '24

22 Apr '24

A few years back, I tried using endnotes with ConTeXt-SBL, and it failed to compile. I'm forced to try again (due to some other issue with footnotes), and instead of compiling to error, it compiles, but the footnote's message ends up being empty. Why is it appearing empty? Is there a fix? Here is a minimum working example: \usemodule[publ-imp-sbl] \startbuffer [bib] @Article{na2006, title={Volcanoes \word{of} New Mexico}, year={2006}, journal={New Mexico Earth Matters}, publisher={New Mexico Bureau \word{of} Geology \word{and} Mineral Resources}, volume={6}, number={1}, location={Socorro, New Mexico} } @Book{clark1989, author = {Clark, William}, title = {Railroads \word{and} railroad towns \word{in} New Mexico}, publisher = {New Mexico Magazine}, year = {1989}, address = {Albuquerque, New Mexico}, isbn = {9780937206126} } \stopbuffer \usebtxdataset[bib.buffer] \setupbtx[dataset=default] \usebtxdefinitions[sbl] \setupbtx[sbl] \setupnote[footnote][location=none] \starttext \input knuth \cite[clark1989] \placenotes[footnote] \startchapter[title=Bibliography] \placelistofpublications \stopchapter \stoptext --Joel

How to isolate serious errors from warnings?
by Joel 20 Apr '24

20 Apr '24

I'm about to have a lengthy (2,000+ page) document published. Normally if it compiles and looks okay, I regard that as meaning no errors appeared, but I've noticed that sometimes ConTeXt will still compile, even if something isn't displayed on screen as it should: (1) I tried placing a table inside a startitemize environment, as instead of it not compiling, it left a message in the document warning that wasn't supported. (2) In another case, I had an image that ConTeXt couldn't find, as I mispelled the filenmame, and it fully compiled and made a PDF, without me noticing. (3) Or maybe in some case, a font couldn't be found for a specific character, so a single character in the file isn't displaying. Those are just some examples; I intended for something to be printed on the PDF, but it isn't showing there. Since a document of this size will have a lot of messages, is there a way to adjust the settings, from "show everything" to "show some" to "show only serious errors"? Or maybe to use > to send the errors to another file for careful study? (using Linux if that matters) --Joel

Most recent context doesn't like synctex?
by Jim 15 Apr '24

15 Apr '24

Hi, I have both TeXlive 2024 and the stand-alone ConTeXt distribution on my system. Recently, the stand-alone ConTeXt distribution seems to not create a synctex file any more. Specifically, /usr/local/context/tex/texmf-linux-64/bin/context --once --texutil --synctex=1 --nonstop file.tex does not create a .synctex file (and deletes it, if it is there), whereas the TeXlive version /usr/local/texlive/2024/bin/x86_64-linux/context --once --texutil --synctex=1 --nonstop nwg_newsletter_2024_04.tex does create the .synctex file. The ConTeXt distribution version *does* create the file if --nonstop is *not* used. Knowing that, I can work around this for now, although emacs+auctex probably won't be happy without --nonstop. I updated the stand-alone ConTeXt a few minutes ago, so I'm up to date on that. Is this a bug introduced by some recent change? Thanks. Jim

That seems to be a bit tricky, at least for me. (I'm afraid that \getmarking[xxx][top] was intended for that and it is not feasible at all.) At page 1 the header should read "secA", at page 2 again "secA" (because the very first text belongs to "secA"), and at page 3 "secC" (because the very first text (the section title) belongs to "secC"). Unfortunatly \getmarking[][] does not behave like I expacted. I understand the keywords of \getmarking in the wiki (https://wiki.contextgarden.net/Command/getmarking) as listed below: • previous: marking at the bottom of the page BEFORE the current page (no page before then empty) • next: marking at the top of the page AFTER the current page (no page after then bottom of current page) • top: marking at the top of the current page • bottom: marking at the bottom of the current page • first: first marking that starts at the current page (no first than behaving like top) • last: last marking that starts at the current page (no last than behaving like bottom) • current: last stored marking while deciding on pagebreaking between the current page and the (potential) following page • default: first According to these thoughts, I started with \getmarking[Datum][top]. But "top" seems not to work, there is no difference between "top" and "first", "top" behaves like "first". My second thought: Generally \getmarking[Datum][first] would be perfect, so I've thought something like \doifelse{\fetchmark[Datum][next] of the page before the current page}{\fetchmark[Datum][previous]} {\getmarking[Datum][previous]} {\getmarking[Datum][first]} could work. (Honestly I don't know how to do "\fetchmark[Datum][next] of the page before the current page}". The first page would need a special treatment too.) But: At page 2 \getmarking[Datum][next] (Nx) contains "secB" but at top of page 3 is not "secB" but "secC". So \getmarking[Datum][next] does not seem to contain the correct information I need, therefore I don't get any further. Any ideas: How do I write the marking of the very first text at the current page to the header? Thank you in advance, Matthias

Back in the 90s
by Riviera Taylor 13 Apr '24

Hello, I was reading about the history of ConTeXt in the Not So Short Introduction To ConTeXt and I have a historical question. I noticed that the PDF specification was published in 1993 yet ConTeXt was invented in 1991. The book suggests that PDF output was handled by the PdfTeX engine in MKII in 2005. What sort of output did the software produce before PdfTeX was introduced? Was this the same as the output produced by the software before the publication of the PDF specification? Kind regards, Riviera she, her, hers https://wiki.contextgarden.net/User:River

Very bizarre bug
by Thomas A. Schmitz 07 Apr '24

07 Apr '24

Hi everybody, this is bizarre, but hear me out: a file that I have has a mixture of xml, TeX and Lua. It compiles cleanly, no problem, on macos and linux. I also have a little raspberry pi on which I have installed lmtx. The file compiles, BUT: it has one additional page. The first page of the document is empty and has the word "on" in the upper left hand corner of the text area. I have checked several times, it always comes out like this. Everything else is exactly the same - context version, file and environment files (everything under git, so really identical). The "on" does not appear if I just make a "hello world" document on the raspi. So my question is: how can I begin to explore where this word creeps in? I suspect it's something in the linux-aarch64 tree or some test for this architecture that is the culprit, but what would be a good way to trace it? All best Thomas

incosistent output of --- dash
by madiazm.eoicc＠gmail.com 07 Apr '24

07 Apr '24

Hi everyone, I'm a bit puzzled because I usually don't get an em-dash when I type tree hyphens. If I use the command \emdash, no problem but when I use the hyphens some days it works... and somedays I see three small hyphens. I tried it on overleaf and of ContextOnWeb with the same inconsistency. If I create a new file it usually works right; but when I overwrite an existing file subtituting a hyphen for three where the dash should be I sometimes get it right and sometimes wrong. It is not the pdf viewer since I get good or bad results in all, the overleaf pdf preview tool, the context on web preview tool and the mozilla integrated pdf viewer. Am I missing something on the use of this ligature? (the question is just out of curiosity, since I plan to create a command that adds a hairspace after or before the dash, since I don't like it to stick to some letters like "o". thanks

statistical charts module re-published
by Henning Hraban Ramm 05 Apr '24

Hi, since the Akela server at Mendel University is down since a while, I got no response from Tomáš, and it would be a pity to lose this module, I re-published the statistical charts module at https://codeberg.org/fiee/context-statistical-charts I’ll also put it on modules.contextgarden.net This is version 0.31, tagged by me as 2020-09-11 (date of the presentation). I’m sure there’s a newer version somewhere, at least at Ramkumar’s, and I’d like to update the repo to that. Also the sources for the documentation are missing. Authors, please help me save your work! Hraban

Have a look at these beautiful font designs: https://esadtype.esad-amiens.fr/ Unfortunately the fonts are not available (yet). Take your time to browse the papers about intention, design process etc. I just browsed the dissertation about the (Vietnamese) "Dilinh" font and found the considerations interesting. "Gul" has matching Devanagari & Latin, "Tarisel" has variations from readable text to abstracted lombardic unciale, and "Wierd" has matching deconstructivist outlines for Arabic & Latin… Hraban

what about "textdisplay"?
by Henning Hraban Ramm 02 Apr '24

02 Apr '24

A while ago, I was pointed (by Wolfgang or Hans, I guess) to \start/stoptextdisplay to enhance whitespace handling around images. I wanted to document it, but can’t find it in the sources: $ context --find=textdisplay mtx-context | …/tex/texmf-context/doc/context/sources/general/manuals/ontarget/ontarget-profiles.tex mtx-context | mtx-context | 196 \starttextdisplay … mtx-context | 277 \stoptextdisplay mtx-context | mtx-context | …/tex/texmf-context/doc/context/sources/general/manuals/ontarget/ontarget-standardize.tex mtx-context | mtx-context | 888 \starttextdisplay … mtx-context | 941 \stoptextdisplay mtx-context | These two documents use it and compile flawlessly.

context editor support / syntax highlighting for Pulsar
by Henning Hraban Ramm 01 Apr '24

01 Apr '24

Hi Hans (et al.), find attached a slightly extended version of the "interface" script that can also generate the list of commands in cson format for Pulsar/Atom. It just creates a basic list of commands for syntax highlighting; for a complete plugin, "grammars" and "settings" are missing, see https://codeberg.org/fiee/language-context (Yes, this approach is oldfashioned and a plugin could do a lot more, but I don’t speak TypeScript.) The generated cson file is for "snippets", like in: https://codeberg.org/fiee/language-context/src/branch/master/snippets/langu… There, I added information from the interface files and also from the wiki, if existing. I don’t know how to do that in the lua script. --- function flushers.pulsar(collected) for interface, whatever in next, collected do local commands = whatever.commands local environments = whatever.environments local result, r = { }, 0 r = r + 1 ; result[r] = "'.text.tex.context':\n" for i=1,#commands do r = r + 1 ; result[r] = format("\t'\\%s':\n",commands[i]) r = r + 1 ; result[r] = format("\t\tprefix: '%s'\n",commands[i]) -- can we have some information? --r = r + 1 ; result[r] = format("\t\tdescription: 'level: primitive; interface: i-tex.xml'",'') -- no URL if command starts with "stop" r = r + 1 ; result[r] = format("\t\tdescriptionMoreURL: 'https://wiki.contextgarden.net/Command/%s'\n",commands[i]) end io.savedata(format("language-context-%s.cson",interface), concat(result),"\n") end end --- Also, the "en" interface is empty, everything is in "common", so the iteration over interfaces makes no sense here. Actually, Atom/Pulsar could work with a tree sitter parser (https://github.com/pmazaitis/tree-sitter-context) but I don’t know how to use it. [TextMate] For TextMate and other editors that use TM bundles, it might make sense to update https://github.com/pgundlach/context.tmbundle At least the list of commands could be automatically converted from the interface files, but it’s more involved than what mtx-interface does. [Visual Studio Code / VSCodium] BTW, is the ConTeXt language server for VS Code public anywhere? (Ramkumar KB promised…) Or is "mtxrun --script=vscode --lsfile" the same? Hraban

upload
by Hans Hagen 01 Apr '24

01 Apr '24

Hi, There is a new lmtx upload. -- The svg inclusion via metapost has been upgraded and cleanup a bit, using some more recent metapost features. There are some new (not yet all documented metapost) features. -- In the process, support for LCH colors has been added, which is documented in the (eg luametafun manual). -- The math manual is not yet there because we were distracted by improving support for envelopes (penbased outlines) in metafun. This is still work in progress, some is present and discussed in the manual, and we'll come back to that sometime next month. Given the next item, we also might need to change some in the manual (different focus). -- Because we have users who have to conform to the European Accessibility Act we have been wondering how to deal with that and at Mikaels place there are two demands: distinctive colors and tagging and especially math (somehow validators love to check that). Colors never were an issue as they can be controlled, and tagging math neither, especially because nothing was/is done with it anyway, but ... we are happy that we found a reasonable (more modern and future proof) way out. As explained / shown in the attached document we're basically forced to choose a different approach with math (a pity as we worked hard to get the rendering right but the attached file works fine in the viewers that we tested). -- We like to hear from users what other demands wrt accessibility there are. We're not interested in the (commercial) big money aspects (of pdf and tagging) nor in the politics behind it (changes over time). What are the demands, so that we can see how to make it work or just work around it (as it's kind of boring to cook uyp complex features , esp compared to playing with metapost). -- Furthermore .. the usual bits and pieces as discussed on the list and otherwise. -- If you have troubles (crash) you need to wipe the cache due to a change in lua bytecode storage (no easy way to catch it).

How to get an image to fill the maximum available space?
by Joel 30 Mar '24

30 Mar '24

I have code like this: \placefigure[here, force]{my caption}{% \externalfigure[#1][frame=on, maxheight=1.2\textwidth, maxwidth=\textwidth]% }% I need some images to appear in a book. I need them to keep their proper ratios, but scale up to the maximize the available space. The image can't be more than \textwidth wide, and can't ever be more than 1.2\textwidth high. The problem I am getting with this code, and it does seem to be limiting the images to be not bigger than those two dimensions above, is some of the images, for reasons I can't understand, are appearing really tiny and aren't scaling up to fill as much space as is possible. I can't explain why this is happening--the images themselves are very very high resolution. Is there any way to modify the code to make sure the image stretches up to be the biggest it can, without exceeding the sizes I've listed? --Joel

Visually balanced columns
by Alexey Kryukov 27 Mar '24

27 Mar '24

Hi list, I'd like to know if its is possible to get visually balanced mixedcolumns in lmtx. For example, if I have \blank's between paragraphs, I would like them to be stretched or expanded by a such way that the bottommost lines have the same vertical position -- no matter, how many lines there are in each column and how exactly they are aligned. If I understand correctly, that's how the multicols environment in LaTeX works, and that's how old-multicolumns worked -- but this module seems to be no longer supported in lmtx. I tried to disable gridfitting for startcolumns, but it produces a completely distorted output. -- Regards, Alexey Kryukov <anagnost at yandex dot ru> Moscow State University Faculty of History

start/end pages in ToC
by Alan Bowen 26 Mar '24

26 Mar '24

Our journal is currently in the process of moving to continuous publication of items in a given volume as they are ready. This entails re-jigging the ToC so that it now includes the start and end page numbers of each item. So far, I have everything pretty much in the right place, but for the page numbers I am getting only “??”. I am not sure why this is happening and would be grateful if someone could tell me why or point me to documentation that explains the problem and how to solve it. Many thanks in advance. My minimalish working example: \definehead[SourceTitle][chapter] \setuphead[SourceTitle][page=yes, footer={ItemData}] \definehead[StudyTitle][chapter] \setuphead[StudyTitle][page=yes, footer={ItemData}] \definetext[ItemData][footer][ {\at[\Reference]– \at[\namedstructureuservariable{}{authorInitials}endPage]} ] \setuplist[SourceTitle][ state=start, textcolor=black, alternative=startendpages, criterium=all, headnumber=no, interaction=page, numberalign=flushright, before={\blank[2.2ex, fixed]}, inbetween=\endgraf, ] \setuplist[StudyTitle][ state=start, textcolor=black, alternative=startendpages, criterium=all, headnumber=no, interaction=all, numberalign=flushright, before={\blank[2.2ex, fixed]}, inbetween=\endgraf, ] \define\ToCEntry{% \structurelistuservariable{author}\crlf \structurelistuservariable{title}\hfill% \at[\structurelistuservariable{reference}]–% \at[\structurelistuservariable{authorInitials}endPage] } \definelistalternative[startendpages] [renderingsetup=list:startendpages] \startsetups[list:startendpages] {\ToCEntry} \vglue1pc \stopsetups \starttext {\tfa\bf Contents} \blank[line, fixed] \WORD{Sources} \blank[halfline, fixed] \placelist[SourceTitle][criterium=all] \blank[line, fixed] \WORD{Studies} \blank[halfline, fixed] \placelist[StudyTitle][criterium=all] \page[makeup] \setnumber[userpage][1] \def\Reference{RefSo01} \startSourceTitle[reference={\Reference}, bookmark=Source01, title={}][ title=Source01, author=Author01, authorInitials=ABC, reference={\Reference}, ] \input knuth \page \dorecurse{25}{\input ward\par} \reference[ABCendPage]{} \stopSourceTitle \page[makeup] \setnumber[userpage][1] \def\Reference{RefSo02} \startSourceTitle[reference={\Reference}, bookmark=Source02, title={}][ author=Author02, title=Source02, authorInitials=PQR, reference={\Reference}, ] \input knuth \page \dorecurse{10}{\input ward\par} \reference[PQRendPage]{} \stopSourceTitle \page[makeup] \setnumber[userpage][1] \def\Reference{RefSt01} \startStudyTitle[reference={\Reference}, bookmark=Study01, title={}][ author=Author03, title=Study01, authorInitials=XYZ, reference={\Reference}, ] \input knuth \blank[big] \page \dorecurse{15}{\input ward\par} \reference[XYZendPage]{} \stopStudyTitle \page[makeup] \stoptext Alan

FreeBSD 13.2
by Roger Mason 22 Mar '24

22 Mar '24

Hello, I've been away from ConTeXt for some time but now I want to install it on my FreeBSD 13.2 system(s) (I have not switched any machines to 14.0 yet). After unpacking, running the install scripts results in: ld-elf.so.1: /home/rmason/Software/Context/bin/mtxrun: Undefined symbol "__libc_start1(a)FBSD_1.7" I assume this is because mtxrun is compiled for FreeBSD 14.0. Thus, I need (I think) to compile it for 13.2. Are there instructions somewhere on how to do this? If I get a working installation I'm happy to contribute the FreeBSD 13.2 binaries back to the project, if someone will tell me how. Thanks, Roger

Dear List, On the first page I had this example: \definepapersize[MyBook][width=19cm,height=29.7cm] \setuppapersize[MyBook][MyBook] % Prints on paper the size of MyBook %\setuppapersize[MyBook][A4] %Would print MyBook-size pages on A4 paper \setupbodyfont[modern, 12.50pt] \definemargindata [MyInMargin][inleft] \definemarginframed[MyInMargin][topframe=on,bottomframe=on,rulethickness=1pt,width=1.90cm] \defineenumeration [theorem] [ text=Theorem, title=yes, width=fit, distance=0.2em, alternative=serried, ] \definetextbackground[GrayBackground][ location=paragraph, background=color, backgroundcolor=lightgray, leftoffset=.5\bodyfontsize, rightoffset=.5\bodyfontsize, topoffset=.5\bodyfontsize, bottomoffset=.5\bodyfontsize, frame=off,] \margintext{\blackrule[color=black, height=0.10ex, width=1cm]\\} \blackrule[color=black, height=0.10ex, width=13.50cm] \starttext \margintext {1.1.1} {\bf Beispiel 3.2.17. (Vertauschung von All- und Existenzquantor).} \par So I have here an example from the second page: \definemargindata[inrightmargin][right][margin=margin,width=.50em\rightmarginwidth,style=,color=] \definemarginframed[MyInMargin][topframe=on,bottomframe=on,rulethickness=1pt, width=.90cm] \blackrule[color=black, height=0.10ex, width=13.40cm] {\blackrule[color=black, height=0.10ex, width=1cm, distance=.90cm]\par \defineenumeration [theorem] [ text=Theorem, title=yes, width=fit, distance=0.2em, alternative=serried, ] \inright{3.2.22} {\bf Theorem 3.2.22 (Rechenregeln für Quantoren)}. Seien \m P(\m x)und My problem here is that there is not the same distance between the the text and the margintext . And now the margintext should be on the right side. So maybe someone could help me please. Many thanks.

Use of marking
by Thomas Meyer 22 Mar '24

22 Mar '24

HI folks, yesterday while reading along I learned how to suppress the chapter numbers in sections. That was something I was looking for myself. But how do you use marking correctly in startsection? I would like to see "1. Kapitel - 1. Aufgabe" in the header on the right. How can I automate this with marking? And how can I reduce the space between the number (1.) and the title (Kapitel or Aufgabe)? Thanks for your help Thomas

Hi, When inserting pages with \copypages, the included pages are slightly shifted to the left and to the bottom. Minimal example: % test-file.tex: \setuplayout[page] \starttext \input tufte \vfill \input tufte \stoptext % test.tex: \starttext \copypages[test-file.pdf] \stoptext How could I avoid this offset please?

command line arguments

Following up on the other imposition question, I'm trying to make an example file that shows an imposition schema according to command line arguments. This way it works for the number of pages, as used in \dorecurse{\Pages}{…}, but not for the imposition schema. Typesetting \Schema looks right, but \setuparranging doesn’t work. Where's my error? \def\Schema{\doifelsedocumentargument{schema}{\getdocumentargument{schema}}{1*8}} \def\Pages{\doifelsedocumentargument{numberofpages}{\getdocumentargument{numberofpages}}{16}} \setuparranging[\Schema] Find the full example attached, I call it like context --autopdf=auto --arrange impositiontest.tex --schema=TRYPTICHON --numberofpages=32 Hraban

Re: can we do binding correction?
by Andres Conrado Montoya 20 Mar '24

20 Mar '24

There is some mention of a mechanism to get binding correction from an old article in the wiki about emulating the Koma TypeArea from LaTeX, you can see it in https://wiki.contextgarden.net/KOMA-scrartcl_Type_Area There is also some discussion about the subject in SE: https://tex.stackexchange.com/questions/38682/rules-of-thumb-for-size-of-bi… However, that discussion is 12 years old and the links referenced as sources are dead now. I have found with experience that a formula to calculate the binding correction for a saddle stitch binding, not more than 4 pages in a signature (only one fold in the middle) usually is 1/2 the circumference of a circle with radius *r*, being *r* the thickness of the paper times the amount of physical signatures. Something like: \frac{π \times t \times s}{2}. I have not tried a formula for more folds in a signature. The thing is, you have to recalculate for each signature fold. The innermost will have displacement zero, the second one a little bit more, the third a little bit more, and on and on until we reach the outermost signature. However, it is necessary to say that unless you are using a particularly thick paper, or you are using too many pages for a saddle stitch bind (my personal and professional opinion would be no more than 80, but better 60), the displacement is usually negligible. For example, let's say the paper thickness is 0.1 mm (which is 0.0001 meters) and there are 40 pages in 10 signatures. The radius would be 0.0001 meters per signature * 10 signatures = 0.001 meters. Then, half the circumference would be 1/2 * 3.14159 * 0.001 meters ≈ 0.0016 meters or 1.6mm at the last signature. Unless there was a displacement of more than, say, 4 mm, I wouldn't worry too much about it. -- Andrés Conrado Montoya Andi Kú andresconrado(a)gmail.com http://sesentaycuatro.com http://messier87.com http://chiquitico.org ---------------------------------------- Los fines no justifican los medios, porque la medida verdadera de nuestro carácter está dada por los medios que estamos dispuestos a utilizar, no por los fines que proclamamos. ---------------------------------------- “You develop an instant global consciousness, a people orientation, an intense dissatisfaction with the state of the world, and a compulsion to do something about it.

can we do binding correction?
by Hraban Ramm 20 Mar '24

20 Mar '24

Hi, this question was rised in my ConTeXt beginners workshop* at Chemnitz Linux Days today: Can I configure binding correction for saddle-stitched or thread-bound booklets, and if, does it only work with arranging (imposition) or can I enable it somehow for the layout (if the printshop does the imposition)? Also I recognized I'm not sure about the difference of the layout parameters backspace and cutspace. Hraban *) 8 participants who endured 3 hours of me mostly talking… Further questions that I couldn't answer for sure were about PDF/A or PDF/UA and how color profiles are handled within ConTeXt and at printshops (my monitor is profiled, but I know I have to edit images "too bright" to have them look right in print). I need to investigate further before I can ask precise questions. When JUH yesterday had his shorter talk about "corporate publishing with Markdown and ConTeXt", the lecture hall was stuffed.

Adjusted Chapter Headings

I have some style adjustments for the chapters. The chapter "numbers" need to be Boek I, Boek II, etc. A vertical separator was introduced with an inframe.

Hi all, I've had a few patches applied to my installation for a little while now, so I figured that I should send them in.

See the definition of "l_checkmodep" in "liolib.c". * Some of the pgfplots 3D shaders appear to be broken, see https://tex.stackexchange.com/a/708121 . * The TikZ "RGB" colour model does not currently work properly.

How to track down source of [entry not flushed] displaying in indexes?
by Joel 14 Mar '24

14 Mar '24

I have some custom registers that I use to index some information. When compiled, it just prints [entry not flushed] instead of printing some of the page numbers. I have tens of thousands of lines of code, so have no idea how to break the problem down to a minimal example. What does [entry not flushed] mean? What kind of feature in my document do I need to search for that might explain why this is appearing? Here is the minimal code used in my index, as you see it isn't showing the error, so something else in the document is causing it: \setvalue{W3}{this is text for W3} \defineregister[learnedshort][compress=yes] \setupregister[learnedshort][style=sansbold, textstyle=slanted, n=3, pagenumber=yes, indicator=no] % \defineregister[learnedlong][compress=yes] \setupregister[learnedlong][style=sansbold, textstyle=slanted, n=2, pagenumber=yes, indicator=no] % \define[1]\learnedis{% \txt{} \getvalue{#1} \learnedshort{#1} \learnedlong{#1} } \define[1]\learned{% \textreference[textref#1]{\expanded{\currentstructuretitle}} \reference[ref#1]{}% % \learnedshort{#1} \learnedlong{\getvalue{#1}} } \starttext \learned{W3} \startchapter[title=Standards] \placeregister[learnedlong] \stopchapter \stoptext

Creating a module for calligraphy practice templates
by Andres Conrado Montoya 12 Mar '24

12 Mar '24

Hello, list! I've been working on a module to typeset calligraphy practice templates using ConTeXt and MetaPost. You are welcome to check it out on github: https://github.com/conradolandia/pauta I'm not including a MWE because the repository has all the current code. I hope this is fine. I did not want to clutter the list with too much text. The module is only a single file (t-pauta.mkxl) and some examples of use and documentation that are still somewhat unfinished, but I've tried to document the source code as much as I could. If you need clarification about anything, please let me know. (At the root of the repository, there is a file build.lua, that is not really part of the project, just a custom tool I use to process the files, a sort of minimal build system. You can ignore it.) I welcome any kind of suggestions and dire warnings. I've tried to read the wiki and the manuals carefully and made as many tests as possible, and in general it works fine, but I have ADHD and things frequently get over my head. There are still some things that don't work as they should, and things that need improvement: 1. I use top/bottom areas to display some info. These areas are not being handled properly so far. For example, if I place a chapter before the Pauta macro invocation, there will be data on the top and bottom areas in the last page of the chapter. I've tried using \page and clearing the areas, which feels like cheating, but still does not work well. Any ideas on how to better handle this are more than welcome. 2. I'm using what I found at https://wiki.contextgarden.net/System_Macros/Handling_Arguments and \getparameters to handle the arguments for my Pauta macro, but today I found out about \processaction at https://wiki.contextgarden.net/Module_Parameters and I'm not really sure if I should change my module to work with this instead of \getparameters. In general, after checking the source code of several modules, I'm not really sure how much I have to follow the guidelines at https://wiki.contextgarden.net/Module_Parameters or if those are the most current recommendations. 3. I'm including in my module the code of the file hatching.mp that can be found at https://ctan.org/tex-archive/graphics/metapost/contrib/macros/hatching. I did this for portability reasons, since it's less than 70 lines and has not been updated in 20 years. But if it's better to have this in a separate file, please let me know. Also, if a better method to create pattern filled paths is available, please let me know, I confess I didn't look too much into it yet. This has solved my requirement so far. 4. I want to be as close as possible to the new LMTX syntax and way of doing things. so If you think I'm doing something in anachronistic ways, please let me know. In general, if someone wants to check it out and provide feedback so I can improve it, with the objective of eventually being shared on modules.contextgarden.net, will be much appreciated.

update
by Hans Hagen 11 Mar '24

11 Mar '24

Hi, Todays update has a fix for the compact mode slant interference (as explained by Wolfgang a few days ago). Hopefully that works out well. We (MS and HH) also managed to make curve detection more accurate (the decision routine that is responsible for straight lines in the MP output) so that extreme paths with control points way beyond reasonable still produce the right output (before we could get a wrong bbox due to clipping the curve in the backend). One can actually also force "always curve" with "withcurvature 1" (more variants might follow) but that is more or us to have a test option. Curvature detection is mostly a pdf efficiency feature and normally users should rely on the default to work okay. Other new mp features are relative and absolute points which makes it possible to define paths in a turtle graphics way (a bit like hlineto and vline in postscript), a native "--" operator (equivalent but somewehat more efficient on huge generated paths). The luametafun manual has a chapter on paths that describes some of this. Yet another new feature is "firstcontrol" and "secondcontrol" that is an addendum to controls that makes both control points the same when only one is given. Finally there is a fix in mp where some directions, think { dir 120 }, gave the wrong result due to sign swapping (so it was seen as { dir 200} or { dir -60 }) as side effect of negative zeros fed into tan2. This became obvious when MS reprocessed a graphic, as last year we switched from scsled (no bug) to double (long time bug exposed). (The bug is also present in LuaTeX double/binary mode but it will be fixed there too.) The rest is not (yet) worth mentioning, Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | www.pragma-ade.nl | www.pragma-pod.nl -----------------------------------------------------------------

issue with module update
by Pablo Rodriguez 11 Mar '24

11 Mar '24

Dear list, I have just updated a module named PresVoz. I get the standard directory (https://modules.contextgarden.net/dl/presvoz/) and (https://modules.contextgarden.net/dl/presvoz-{%version%}.zip) but no https://modules.contextgarden.net/dl/presvoz.zip (with current version). So when updating the module, I get it only uninstalled. The two most recent updates (this one and the one before) had this issue. Is there something I am missing here?

weird character normalization in the wiki
by Pablo Rodriguez 11 Mar '24

11 Mar '24

Dear list, https://wiki.contextgarden.net/Greek#Monotonic_and_Acute_Accent includes two samples that should display the difference betweeen the monotonic accent and the polytonic acute accent (which generate two different characters for each such accented vowel). Excluding other implications, these are two different characters. In some fonts each pair of different characters for each accented letter lead to the same glyph, in other fonts those glyphs are different. This sample shows the difference (there should display two slightly different accents [unless there is some character normalization on the way]): \definefontfamily[mainface][rm][EBGaramond] \setupbodyfont[mainface, 500pt] \definecolor [tred] [r=1,t=.5,a=1] \definecolor [tblue] [b=1,t=.25,a=1] \starttext \startTEXpage[offset=1ex] \startoverlay {\color[tred]{Ά}} {\color[tblue]{Ά}} \stopoverlay \stopTEXpage \stoptext The problem that I have is tricky. Thanks to character normalization (at least in Firefox), searching for "á" will also find "a" (unless “Match diacritics” is enabled). I’m afraid the wiki is performing some character normalization, which renders samples in https://wiki.contextgarden.net/Greek#Monotonic_and_Acute_Accent useless. Searching for "Ά" in https://wiki.contextgarden.net/Greek should give not more than 4 matches (not case-sensitive and with “Match diacritics” [or similar filter for your browser] enabled). I‘m afraid I get none. While editing the article searching for "Ά" (case-insensitive and not normalizing characters), gave me 4 matches, but only in the source (no ocurrence was found in the preview). Once changes are saved, "Ά" occurrences dissapear (since they seem to be normalized). Sure, they may be a workaround to type codepoints instead of characters (such as with \utfchar{0x1fbb}, but wouln’t it be possible to disable that character normalization in the wiki? Many thanks for your help, Pablo

has the statistical charts module a new home?
by Henning Hraban Ramm 11 Mar '24

11 Mar '24

Hi Tomáš et al., the site https://akela.mendelu.cz/~thala/statcharts/ and actually the whole server disappeared. Is there a new download location for the charts module? It would be nice if we could just host it on https://modules.contextgarden.net, then it could also get installed via the mtxrun script. Hraban

How to set section title based on section content?
by Joel 09 Mar '24

09 Mar '24

How to set section title based on section content? I have a document that has some structures like this: \starttext \startsection[title={Animals}] \event{\input knuth } \stopsection \startsection[title={Books}] \event{\input knuth } \stopsection \stoptext The event macro runs a bunch of conditionals, deciding which content to place inside the section. It places any one of neary 200 possible different types of content there. Sadly when I wrote the code, I thought generic titles would be okay. Now I realize I need to be more specific, giving titles that match the content inside. I could move the section titles inside the \event macro, but it means rewriting ~200 other macros. In other words, how do I define a section title by defining it somewhere in the content of the \event macro? \starttext \startsection[\whatistitle] %<-- would display "Neon Tetras" \event{\thetitleis{Neon Tetras}\input knuth } \stopsection \startsection[\whatistitle] %<-- would display "Detective Stories" \event{\thetitleis{Detective Stories}\input knuth } \stopsection \stoptext

Font version parse question

Hello all, The font tweak file libertinus_math.lfg tests for a font version of *7.040*, but the result of the version parse is *7.040;RELEASE*, resulting in an error message. I do not know if this is the fault of the parser or of the font metadata. Changing the test in the .lfg file fixes the error, but that is not a long-term solution. The exact message I get in the log is: mathematics > tweak > 'LibertinusMath-Regular', size 10, math size 0, version 'Version, 7.040;RELEASE' found, version 'Version 7.040' expected This is not a high-priority issue for me -- I have nothing in this document that would benefit -- but others may appreciate a fix. -- Rik

multicolumn title and abstact (bachotex) using tugboat.mkxl
by damien＠thiriet.web4me.fr 07 Mar '24

07 Mar '24

Hello, I am currently writing my paper for last year's BachoTeX proceedings. I am using tugboat.mkxl module to design the layout. In bachotex proceedings, the author's data and abstract are on a single column and the article is usually typeset on two columns. Comments in tugboat.mkxl states: %D We have several column mechanisms and they all serve a different purpose. Here we %D use pagecolumns. They support much of what we can do in single columns, but of %D course there are exceptions. Floats can go into columns of aremoved to the top or %D bottom when there is no room. We don't span mid column. Notes can go in columns %D or at the end. We can start with a single column (for titles and such). I can't figure out which part of the file should be used/adapted to start with a single column. What I did is to put datas and abstract in a frame and use \placefigure. As stated in pagecolumns manual, everything is put on the top of next page. (BTW, there is a typo: «of aremoved») I don't know, whether this MWE helps is relevant, but just in case, here is what I did: * copy tugboat.mkxl to a new file p-bachotex.mkxl * changed p-bachotex.mkxl like this: \startsetups bachotex:naglowek:columns \defineframedtext [Dane] \setupframedtext [Dane] [width=18cm , align=normal, frame=no] \definenarrower [Streszczenia] [2*middle] \startplacefigure [location={here,none}] {\startDane {\tfa\getvariable{tugboat}{author}}\par \getvariable{tugboat}{address}\par {\tt\getvariable{tugboat}{email}}\par \startStreszczenia \doifelsebufferempty {abstract} { % no abstract } { \blank[line] \enforced\let\\\endgraf \setups[tugboat:abstract:setup] \startAbstracts[title={Abstract}] \stopAbstracts } \stopStreszczenia \stopDane} \stopplacefigure \stopsetups \startsetups tugboat:article:start \starttext \setups{tugboat:columns:presets} \setups{tugboat:banner:setup:\getvariable{tugboat}{type}} \setupheadertexts [\setups{tugboat:banner:text:article}] [pagenumber] \setuppagenumber [number=\getvariable{tugboat}{page}] \startmode[columns] \startpagecolumns \stopmode \setups[tugboat:introduction:article] \doifmodeelse{columns}{ \setups{bachotex:naglowek:columns} } { \setups{bachotex:naglowek:nocolumns} } \stopsetups My article begins so: \enablemode [columns] \usemodule [bachotex] % skipped tugboat variables for this MWE \StartAbstract \input tufte \StopAbstract \StartArticle \input knuth \StopArticle Thank you for your help Damien T

.jpx and .jxl
by Jim 05 Mar '24

05 Mar '24

Recently I've been trying to make some PDFs smaller by using better compression of JPEG pictures. I was happy to see that \externalfigure cheerfully accepts .jp2 (JPEG 2000) files. However, my understanding (and I could well be wrong, but I've seen it multiple places) is that JPEG 2000 *Part 2* files should have extension .jpx, not .jp2. By default, ConTeXt does not recognize .jpx. But if I rename a .jpx file to have a .jp2 extension, then ConTeXt properly processes the file and I see the picture in the PDF. Q: are there any plans to make ConTeXt recognize the .jpx extension? If not, can anyone suggest some ConTeXt code which allows me to tell ConTeXt to process a .jpx file as a .jp2 file? I have also been investigating the use to JPEG-XL files (.jxl). One of the interesting aspects of JXL files is that .jpg files can be **losslessly** compressed into .jxl files. (That is, you can recover the exact .jpg from the .jxl file if you want, so there is no further degradation of the image by doing this lossless compression.) I have been seeing 20% to 30% reduction in file sizes by converting JPGs into JXLs, which I would be happy to make use of in my PDFs, if possible. Bonus question: is there any plan to support JXL files in ConTeXt? Thanks. Jim

enhancing documentation: initials

It’s defined in context/base/mkiv/typo-drp.lua But I found no difference between first, last, and none; just "auto" includes the mark in the initial, and it works only with a few languages, e.g. English and French, but not e.g. German or Dutch: """ \mainlanguage[de] \setuppapersize[A6] \setupinitial[n=2,color=orange,] \starttext \start \setupinitial[method=first] \placeinitial \quotation{Keine andere Kunst hat mehr Berechtigung, ihren Blick auf die zukünftigen Jahrhunderte zu richten als die Typographie.}\wordright{Giambattista Bodoni} \stop \start \setupinitial[method=last] \placeinitial \quotation{Nationalökonomie ist, wenn die Leute sich wundern, warum sie kein Geld haben.}\wordright{Kurt Tucholsky} \stop \start \setupinitial[method=auto] \placeinitial \quotation{Der Mensch wird auf natürlichem Wege hergestellt, doch empfindet er dies als unnatürlich und spricht nicht gern davon.}\wordright{Kurt Tucholsky} \stop \start \setupinitial[method=none] \placeinitial \quotation{Keine andere Kunst hat mehr Berechtigung, ihren Blick auf die zukünftigen Jahrhunderte zu richten als die Typographie.}\wordright{Giambattista Bodoni} \stop \stoptext """

Wiki page : Mixed languages sample (French, Ancient Greek, Arabic, Chinese)
by Jean-Pierre Delange 01 Mar '24

Dear List, Several years ago I tried to write documents, mainly lectures, but also essays, in which I tried to make several languages (Romance and non-Romance) coexist. Here below is an example of an attempt to compose an acceptable document, in the form of an exercise in which Arabic and Chinese are introduced into a document written in French.

Lorsqu'il s'agit de rédiger en français un document un peu complexe, avec des citations — ou des références — dans une autre langue, qui en particulier n'a pas les mêmes exigences que le français, ni les mêmes {\em signes diacritiques} on se heurte à quelques difficultés. Les suites logicielles comme Microsoft Office ou LibreOffice ne manquent pas de puissance, mais à vrai dire, dès que nous entrons dans les exigences de l'édition professionnelle, qui consistent à présenter un texte lisible et enrichi (en notes, etc.), la situation devient vite techniquement assez pénible. La situation la plus courante que nous rencontrons dans les Lettres, en Philosophie, en Histoire, et plus généralement dans les Humanités, est celle d'un texte dans lequel il y a des citations d'auteurs grecs ou latin, avec des références en notes de bas de page, qui contiennent du grec. Cela pourrait être quelque chose comme ceci : \blank\startnarrower[1*left,1*right]\tfx\setupinterlinespace \noindent \quotation{Ἔφη γάρ οἱ Σωκράτη ἐντυχεῖν λελουμένον τε καὶ τὰς βλαύτας ὑποδεδεμένον, ἃ ἐκεῖνος ὀλιγάκις ἐποίει· καὶ ἐρέσθαι αὐτὸν ὅποι ἴοι οὕτω καλὸς γεγενημένος. καὶ τὸν εἰπεῖν ὅτι· Ἐπὶ δεῖπνον εἰς Ἀγάθωνος. χθὲς γὰρ αὐτὸν διέφυγον τοῖς ἐπινικίοις, φοβηθεὶς τὸν ὄχλον· ὡμολόγησα δ᾽ εἰς τήμερον παρέσεσθαι. ταῦτα δὴ ἐκαλλωπισάμην, ἵνα καλὸς παρὰ καλὸν ἴω}. \noindent \quotation{Je rencontrai, dit-il, Socrate, sortant du bain et les pieds chaussés de sandales, ce qui n'est guère dans ses habitudes, et je lui demandai où il allait si beau. Il me répondit : «Je vais dîner chez Agathon.

Cependant, l'utilisation de ce logiciel repose sur un ensemble assez important de déclarations et il est nécessaire d'avoir une longue pratique pour arriver à jouer avec, sinon la puissance, du moins la finesse de \LaTeX. Les commandes sont très nombreuses et il faut recourir souvent à un Manuel pour se remémorer les subtilités qui ont permis d'atteindre tel rendu à l'impression. Bien entendu, il existe des logiciels commerciaux d'aide à l'édition professionnelle pour le secteur des Humanités. Mais d'une part ils sont payants et relativement coûteux pour une personne, sans parler du prix des licences pour les groupements professionnels d'enseignants et de chercheurs. Devant cet état de choses, on peut se tourner vers \ConTeXt, qui n'est pas une alternative à \LaTeX, mais une manière plus synthétique (voire plus élégante) d'utiliser \LaTeX. \ConTeXt, de même que \LaTeX, est une suite logicielle qui contient les macros de \LaTeX, les routines du langage {\em Perl}, ainsi que les macros de \LuaTeX. On peut donc définir à peu près tout ce qui est exigé au niveau de l'édition professionnelle, sans entrer dans la connaissance technique du langage \LaTeX. Bien entendu, on n'échappera pas à un certain nombre de questions techniques, si l'on veut travailler avec ce type d'outil : pour le mathématicien, rendre possible la présentation et l'édition parfaites d'équations complexes, mais aussi de schémas et de tableaux nécessite un apprentissage assez poussé. C'est vrai aussi pour les les utilisateurs qui viennent des Humanités, qui connaissent leur domaine, et qui veulent rédiger un document simple, un article de revue, voir des chapitres entiers d'un ouvrage. Très certainement, ce sont les éditeurs qui se chargent de la mise en page (sur la base d'une feuille de style Word) du document que l'on veut publier. Mais parfois, s'il s'agit d'un dossier de plusieurs articles, voire d'une édition avec une aide financière à la publication, on aimerait avoir la main sur la qualité du document imprimé. C'est une des raisons qui font que l'on pourrait désirer maîtriser la chaîne éditoriale, non seulement pour se passer éventuellement d'un éditeur, mais pour disposer d'un aperçu de son propre travail. \section{Faire coexister du Grec, du Chinois et de l'Arabe dans le même texte} Il n'est pas d'usage commun de lire dans le même document du texte courant en français, une référence en grec, par exemple, lorsque dans le {\em Timée}, Platon indique que le plus difficile est de commencer par un commencement qui soit naturel (κατὰ φύσιν ἀρχήν)\inmargin{Platon, {\em Timée}, 29b.}, une indication du nom du philosophe chinois {\em Tchouang Tseu} (en {\em pinyin}\footnote{Le {\em pinyin} (chinois classique 漢語拼音, littéralement “assembler les sons de la langue des Han”), est une romanisation de la langue chinoise, qui est écrite en alphabet latin. Ainsi, au lieu d'écrire 漢語拼音 en chinois traditionnel, ou bien 汉语拼音 en chinois simplifié, on écrira {\em Hànyù Pīnyīn}.} Zhuangzi et en chinois classique et simplifié : 莊周/庄周). Si l'on ajoute à cela une référence au philosophe arabo-persan Farabi\footnote{Al-Fārābī est nommé dans la philosophie arabe médiévale {\em le second maître}, le premier étant Aristote.} (Al-Fārābī, محمد فارابی), par le biais d'une précision sur Platon, avec des indications sur son nom en arabe, on aura fait le tour de quelques difficultés qui se présentent à ceux qui voudraient établir avec soin des documents un peu exigeants. % \showframe \startMyFrame[Title=Conclusion] \setcharacterspacing[frenchpunctuation] \startlines Pour éditer un texte un peu complexe, avec plusieurs langues non-romanes utilisées occasionnellement, on peut faire appel à \ConTeXt.

Le code est réutilisable et c'est vrai aussi pour les utilisateurs qui viennent des multiples horizons des {\em Humanités}, qui connaissent leur domaine de compétence et qui veulent rédiger un document simple, un article de revue, voir des chapitres entiers d'un ouvrage. \stoplines \stopMyFrame \stoptext

A new problem with space in third itemize
by Ursula Hermann 01 Mar '24

01 Mar '24

Dear List, This is my little example: the problem is, that everything was fine, in itemize 1 and 2. In the third itemize i have a problem, because after n^3 and after \Rightarrow there should be a spaace , if I want to write : \Rightarrow n ungerade, but it says nungerade, what I dont want,. \startitemize[n] {\it \item \m{\forall n ∈ \naturalnumbers:n^2 >n\Rightarrow>1,\par}\nospace \par \item \m{\forall n ∈ \naturalnumbers:3\mid n\Rightarrow 4 \mid n,\par} \nospace \par \item \m{\forall n ∈ \naturalnumbers:n^3 ungerade \Rightarrow n ungerade \par} Uschi

Structuring a magazine or booklet
by Jean-Pierre Delange 29 Feb '24

29 Feb '24

Dear list, I am reading up on how to replace InDesign with CTX when producing a newsletter, using 2 or 3 double-sided A3 sheets containing text in two columns per page (with images). I'm looking for an example of a composition structure. Unfortunately, the wiki page devoted to projects seems meagre. The link to an example given by Hans at the bottom of the page: Hans Hagen (2011) Project Structure, ConTeXt magazine #1101 is a dead link. For example, if I take a notebook consisting of 2 A3 sheets, folded to give 8 pages, the first page, which is an odd page, will be printed on the back of sheet 1, as will page 8. Page 2 is printed on the same sheet, but on the front as an even page. However, note that page 3 (odd) is printed (as an odd page, like page 1) on the reverse of sheet 2. Then pages 4 and 5 are printed on the front of sheet 2, while page 6 faces page 3 on the back of sheet 2. Page 7 is on the same front as page 2 (sheet 1) and finally, page 8 faces (on the back of sheet 1) page 1. My question is this: is there a way to automate the placement of text and images on the right pages with ConTeXt, or do you have to organise everything manually with a layout? Does anyone have more detailed information? I'd be delighted to add this information to the Wiki page. Thank you for your help. JP

\in, \at, and labletext
by Ursula Hermann 29 Feb '24

29 Feb '24

Dear List, In the Documentation IntroCTX_eng_s.pdf at page 170 , I found the two examples with \in and \at, and also the lable. The Problem is, that in the following sentence only the number (3.1) is a placed formula in an example, should have a link. Without the brackets. The sentence says: Task 1: Formulate equivalents according to rule (3.1): Sorry, I have no example. Uschi
