Why does \setvalue not work inside \startbodymatter?
by Joel 19 May '25

19 May '25

I have a document setup with: \starttext\startfrontmatter(contains all front matter content)\stopfrontmatter \startbodymatter \stopbodymatter \startbackmatter \stopbackmatter\stoptext I was noticing very strange behavior where \setvalue was not showing up as \getvalue. I put it in lots of pllaces, but in the main part of the document, it wasn't working. Its like it was never set. After a lot of testing, I discovered if \setvalue is set inside \startbodymatter, its value stays unset. But I can set it in the front matter, backmatter, anywhere else. Here is my minimum working example, note that \getvalue{B} never appears, it was set within the bodymatter. \setvalue{A}{this is a test} \starttext \startbodymatter \setvalue{B}{Why is hits one missing?} \stopbodymatter \startbackmatter \dostepwiserecurse{1}{3}{1}{ \setvalue{C}{this is yet another test} \getvalue{A} \getvalue{B} \getvalue{C} } \stopbackmatter \stoptext What is going on? Should I no longer be using the \startbodymatter, etc. items? --Joel

How to scale a TABLE to \textwidth?
by Joel 19 May '25

19 May '25

I have a large table that spans multiple pages long. Its just about 1" too wide on the page, so I tried using various means to scale it just a little, such that it fits the page width. For example, I tried this way, by wrapping it inside \scale, but that ends up instead of splitting across pages, will and up seemingly putting it in an invisible box and causing it to split and display two (or more) parts side-by-side. Instead of the next part of the table appearing on the second page, it gets rendered really really small, and the second part of the table rendered right next to the first. What's a better solution to making my table fit the \textwidth when its just a bit too wide? --Joel \starttext \scale[width=\textwidth]{ \bTABLE[split=repeat, frame=off, setups=standards, option=stretch] \bTR \bTD \eTD \bTD 1 \eTD \bTD 2 \eTD \bTD 3 \eTD \bTD 4 \eTD \bTD 5 \eTD \bTD 6 \eTD \bTD 7 \eTD \bTD 8 \eTD \bTD 9 \eTD \bTD 10 \eTD \bTD 11 \eTD \bTD 12 \eTD \bTD 13 \eTD \bTD 14 \eTD \bTD 15 \eTD \bTD 16 \eTD \bTD 17 \eTD \bTD 18 \eTD \bTD 19 \eTD \bTD 20 \eTD \bTD 21 \eTD \bTD 22 \eTD \bTD 23 \eTD \bTD 24 \eTD \bTD 25 \eTD \bTD 26 \eTD \bTD 27 \eTD \bTD here is some text \eTD \bTD 29 \eTD \bTD 30 \eTD \bTD 31 \eTD \bTD 32 \eTD \bTD 33 \eTD \bTD 34 \eTD \bTD 35 \eTD \bTD 36 \eTD\eTR%% \bTR \bTD \eTD \bTD 1 \eTD \bTD 2 \eTD \bTD 3 \eTD \bTD 4 \eTD \bTD 5 \eTD \bTD 6 \eTD \bTD 7 \eTD \bTD 8 \eTD \bTD 9 \eTD \bTD 10 \eTD \bTD 11 \eTD \bTD 12 \eTD \bTD 13 \eTD \bTD 14 \eTD \bTD 15 \eTD \bTD 16 \eTD \bTD 17 \eTD \bTD 18 \eTD \bTD 19 \eTD \bTD 20 \eTD \bTD 21 \eTD \bTD 22 \eTD \bTD 23 \eTD \bTD 24 \eTD \bTD 25 \eTD \bTD 26 \eTD \bTD 27 \eTD \bTD 28 \eTD \bTD 29 \eTD \bTD 30 \eTD \bTD 31 \eTD \bTD 32 \eTD \bTD 33 \eTD \bTD 34 \eTD \bTD 35 \eTD \bTD 36 \eTD\eTR%% \bTR \bTD \eTD \bTD 1 \eTD \bTD 2 \eTD \bTD 3 \eTD \bTD 4 \eTD \bTD 5 \eTD \bTD 6 \eTD \bTD 7 \eTD \bTD 8 \eTD \bTD 9 \eTD \bTD 10 \eTD \bTD 11 \eTD \bTD 12 \eTD \bTD 13 \eTD \bTD here is some text \eTD \bTD 15 \eTD \bTD 16 \eTD \bTD 17 \eTD \bTD 18 \eTD \bTD 19 \eTD \bTD 20 \eTD \bTD 21 \eTD \bTD 22 \eTD \bTD 23 \eTD \bTD 24 \eTD \bTD 25 \eTD \bTD 26 \eTD \bTD 27 \eTD \bTD 28 \eTD \bTD here is some text \eTD \bTD 30 \eTD \bTD 31 \eTD \bTD 32 \eTD \bTD 33 \eTD \bTD 34 \eTD \bTD 35 \eTD \bTD 36 \eTD\eTR%% \bTR \bTD \eTD \bTD 1 \eTD \bTD 2 \eTD \bTD 3 \eTD \bTD 4 \eTD \bTD 5 \eTD \bTD 6 \eTD \bTD 7 \eTD \bTD 8 \eTD \bTD 9 \eTD \bTD 10 \eTD \bTD 11 \eTD \bTD 12 \eTD \bTD 13 \eTD \bTD 14 \eTD \bTD 15 \eTD \bTD 16 \eTD \bTD 17 \eTD \bTD 18 \eTD \bTD 19 \eTD \bTD 20 \eTD \bTD 21 \eTD \bTD 22 \eTD \bTD 23 \eTD \bTD 24 \eTD \bTD 25 \eTD \bTD 26 \eTD \bTD 27 \eTD \bTD 28 \eTD \bTD 29 \eTD \bTD 30 \eTD \bTD 31 \eTD \bTD 32 \eTD \bTD here is some text here is some text here is some text here is some texthere is some texthere is some texthere is some texthere is some text\eTD \bTD 34 \eTD \bTD 35 \eTD \bTD 36 \eTD\eTR%% \bTR \bTD \eTD \bTD 1 \eTD \bTD 2 \eTD \bTD 3 \eTD \bTD 4 \eTD \bTD 5 \eTD \bTD 6 \eTD \bTD 7 \eTD \bTD 8 \eTD \bTD 9 \eTD \bTD 10 \eTD \bTD 11 \eTD \bTD 12 \eTD \bTD 13 \eTD \bTD 14 \eTD \bTD 15 \eTD \bTD 16 \eTD \bTD 17 \eTD \bTD 18 \eTD \bTD 19 \eTD \bTD 20 \eTD \bTD 21 \eTD \bTD 22 \eTD \bTD 23 \eTD \bTD 24 \eTD \bTD 25 \eTD \bTD 26 \eTD \bTD 27 \eTD \bTD 28 \eTD \bTD 29 \eTD \bTD 30 \eTD \bTD 31 \eTD \bTD 32 \eTD \bTD 33 \eTD \bTD 34 \eTD \bTD 35 \eTD \bTD 36 \eTD\eTR%% \bTR \bTD \eTD \bTD 1 \eTD \bTD 2 \eTD \bTD 3 \eTD \bTD 4 \eTD \bTD 5 \eTD \bTD 6 \eTD \bTD 7 \eTD \bTD 8 \eTD \bTD 9 \eTD \bTD 10 \eTD \bTD 11 \eTD \bTD 12 \eTD \bTD 13 \eTD \bTD 14 \eTD \bTD 15 \eTD \bTD 16 \eTD \bTD 17 \eTD \bTD 18 \eTD \bTD 19 \eTD \bTD 20 \eTD \bTD 21 \eTD \bTD 22 \eTD \bTD 23 \eTD \bTD 24 \eTD \bTD 25 \eTD \bTD 26 \eTD \bTD 27 \eTD \bTD 28 \eTD \bTD 29 \eTD \bTD 30 \eTD \bTD 31 \eTD \bTD 32 \eTD \bTD 33 \eTD \bTD 34 \eTD \bTD 35 \eTD \bTD 36 \eTD\eTR%% \bTR \bTD \eTD \bTD 1 \eTD \bTD 2 \eTD \bTD 3 \eTD \bTD 4 \eTD \bTD 5 \eTD \bTD 6 \eTD \bTD 7 \eTD \bTD 8 \eTD \bTD 9 \eTD \bTD 10 \eTD \bTD 11 \eTD \bTD 12 \eTD \bTD 13 \eTD \bTD 14 \eTD \bTD 15 \eTD \bTD 16 \eTD \bTD 17 \eTD \bTD 18 \eTD \bTD 19 \eTD \bTD 20 \eTD \bTD 21 \eTD \bTD 22 \eTD \bTD 23 \eTD \bTD 24 \eTD \bTD 25 \eTD \bTD 26 \eTD \bTD 27 \eTD \bTD 28 \eTD \bTD 29 \eTD \bTD 30 \eTD \bTD 31 \eTD \bTD 32 \eTD \bTD 33 \eTD \bTD 34 \eTD \bTD 35 \eTD \bTD 36 \eTD\eTR%% \bTR \bTD \eTD \bTD 1 \eTD \bTD 2 \eTD \bTD 3 \eTD \bTD 4 \eTD \bTD 5 \eTD \bTD 6 \eTD \bTD 7 \eTD \bTD 8 \eTD \bTD 9 \eTD \bTD 10 \eTD \bTD 11 \eTD \bTD 12 \eTD \bTD 13 \eTD \bTD 14 \eTD \bTD 15 \eTD \bTD 16 \eTD \bTD 17 \eTD \bTD 18 \eTD \bTD 19 \eTD \bTD 20 \eTD \bTD 21 \eTD \bTD 22 \eTD \bTD 23 \eTD \bTD 24 \eTD \bTD 25 \eTD \bTD 26 \eTD \bTD 27 \eTD \bTD 28 \eTD \bTD 29 \eTD \bTD 30 \eTD \bTD 31 \eTD \bTD 32 \eTD \bTD 33 \eTD \bTD 34 \eTD \bTD 35 \eTD \bTD 36 \eTD\eTR%% \bTR \bTD \eTD \bTD 1 \eTD \bTD 2 \eTD \bTD 3 \eTD \bTD 4 \eTD \bTD 5 \eTD \bTD 6 \eTD \bTD 7 \eTD \bTD 8 \eTD \bTD 9 \eTD \bTD 10 \eTD \bTD 11 \eTD \bTD 12 \eTD \bTD 13 \eTD \bTD 14 \eTD \bTD 15 \eTD \bTD 16 \eTD \bTD 17 \eTD \bTD 18 \eTD \bTD 19 \eTD \bTD 20 \eTD \bTD 21 \eTD \bTD 22 \eTD \bTD 23 \eTD \bTD 24 \eTD \bTD 25 \eTD \bTD 26 \eTD \bTD 27 \eTD \bTD 28 \eTD \bTD 29 \eTD \bTD 30 \eTD \bTD 31 \eTD \bTD 32 \eTD \bTD 33 \eTD \bTD 34 \eTD \bTD 35 \eTD \bTD 36 \eTD\eTR%% \eTABLEbody \eTABLE } \stoptext

intent in \setupbackend
by jbf 19 May '25

19 May '25

I have a 2022 version of ConTeXt which I have used for the last 3 years. It has no problem with: \setupbackend [format=PDF/X-1a:2001, intent=SWOP2006_Coated3v2.icc] Recently I set up a separate more recent 2025 version of ConTeXt, and I get an error with the above intent statement. If I remove intent entirely, everything compiles correctly. I don't understand a great deal about the 'intent' statement, so bear with my ignorance. For the most part, whatever I produce is printed in BW/grayscale, not color. Two questions: (1) what has changed with the latest ConTeXt that causes this error with that color profile? (2) If preparing for BW/grayscale printing only, should I be using a different profile? I am assuming I cannot simply omit intent= completely. Julian

Placement of captions in a combination of figures
by Willi Egger 18 May '25

18 May '25

Hello, I need to place several figures into a combination. However the captions of the individual figures appear on the right side, where I would prefer them to appear at the bottom. How to change the location of these captions? \starttext \startplacefigure [location=middle, title=, number=] \startcombination[2*2] {\externalfigure[dummy][width=.5\textwidth]{a}} {\externalfigure[dummy][width=.5\textwidth]{b}} {\externalfigure[dummy][width=.5\textwidth]{c}} {\externalfigure[dummy][width=.5\textwidth]{d}} \stopcombination \stopplacefigure \stoptext Best Willi

issue with "intent=cmyk"
by Pablo Rodriguez 18 May '25

18 May '25

Hi Hans and Mikael, https://www.pragma-ade.com/general/manuals/standards.pdf#page=3 seems to miss the CGATS001Compat-v2-micro.icc color profile "intent=cmyk". But lines 504-506 from lpdf-fmt.lmt read: elseif intent == variables.cmyk then intent = "CGATS001Compat-v2-micro.icc" profile = "sRGB-v4.icc,CGATS001Compat-v2-micro.icc" The grayscale color profile is missing (at least, when compared with "intent=rgb"). Is this actually intended? Many thanks for your help, Pablo

fittingpage dimensions

Hi all! How do you make a fittingpage (or TEX page) that has the same dimensions as all other pages in the PDF file? % snip \definefittingpage[CorruptedPage] \setupfittingpage[CorruptedPage][ width=\paperwidth, height=\paperheight ] \starttext \dorecurse{15}{\input knuth} \startfittingpage[CorruptedPage] \dorecurse{15}{\input ward} \stopfittingpage \stoptext % snip At the very bottom of the pages, the left page is shorter than the right page. current version: 2024.11.01 19:19 Thank you!

Accessibility and typesetting with Context.
by Pawel Urbanski 15 May '25

15 May '25

Hi Everyone, Following up after the side discussion during the meet-up call, here my ideas that can be useful in the accessibility context: 1. Understanding the broader context around the interaction of the PDF readers, screen readers and text-to-speech engines. 2. Drawing attention to the aspects of information that can be or cannot be expressed in different modalities. 3. Giving examples of content and its presentation or interpretation by the assistive technologies in everyday life. Last but not least, I was thinking about doing something like "Ask me anything" on the list to gather questions and do quick and slow responses. I am definitely very eager to try the maths case of preparsing and preinterpreting the tagged output. I will put a simple document to replicate that curious case of Chrome/Brave and Adobe Reader giving differentcontent to NVDA. The list is intentional, for it is a rather broad topic. I want to get the idea what is the most interesting for people in the wild. A side note about me: I had my first experience with Latex years ago, but got back to Context through Pandoc and Markdown. I am working on a book and needed something that gives me stable output and good editing experience. I am blind myself, and have some experience with coding or code reviews. The accessibility aspect developed somehow naturally during my ohter projects. My website for the curious: https://www.pawelurbanski.com/ All the best, Pawel

Enumerations: How to place an itemized list's index above an item's contents?
by Michael Guravage 15 May '25

15 May '25

Greetings, I have 365 short poems; one for each day of the year. I thought I'd wrap each month in an enumeration and use the item numbers as titles. My MWE raises several questions: How do I center an index above its item? How do I keep an index and its item together? How do I keep an item's text together? Here I've resorted to an ugly kludge where I wrap each item in a \start-\stopframedtext pair. What's the right way? Perhaps an itemized list is the wrong approach. Any suggestions would be appreciated. With kind regards, Michael \setupbodyfont[10pt] \usesymbols[mvs] \setupsymbolset [martinvogel 2] \def\ornament{\darkred\symbol[Radioactivity]} \starttexdefinition Ornamentation #1 \framed[frame=on] {\ornament\ {#1}\ \ornament} \stoptexdefinition \starttexdefinition OrdinalDate #1 \Ornamentation{\tfb\getmarking[chapter]\space\ordinalnumber{#1}} \stoptexdefinition \definesymbol [ordinal_symbol] [{\OrdinalDate{\currentitemnumber}}] \setupitemize[symbol=ordinal_symbol] \definestartstop[framedtextitem] [before={\startitem\startframedtext}, after={\stopframedtext\stopitem}] \startbuffer This is a test.

regular online meet-up
by Henning Hraban Ramm 14 May '25

14 May '25

You’re invited to our regular online meet-up, this upcoming Wednesday, May 14th, _20:00_ CEST (UTC+2) at https://lecture.senfcall.de/hen-rbr-rku-oke (same, but shorter: https://u.mtxrun.eu/ctxmtg) Beware, we moved the nominal time one hour later during DLST, so it’s the same as in winter! Last time it looked like this would fit more participants. ConTeXt users of all levels are welcome! Looking forward to seeing you, Hraban (Same blurb as always:) [Howto] * No special software installation required; most modern browsers should work (WebRTC required). * Open the URL above, 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 at a time, 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, esp. with mobile connections. * Sometimes leaving and re-entering helps. * If audio/video doesn’t work for you, you can still use the text chat. * Screen sharing needs a lot of bandwidth. * BigBlueButton documentation applies: https://bigbluebutton.org/tutorials/ [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...

setups issue
by jbf 13 May '25

I have the following command which I am using as part of \setuphead[chapter]: \define[2]\MyChapterCommand% {\framed[frame=on,bottomframe=on,leftframe=off,rightframe=off,topframe=off,align=middle] {\vbox{\headtext{chapter} #1 \blank #2}}} Together with the rest of the \setuphead[chapter] elements, it functions correctly, as indeed it should But as soon as I place the full description of the chapter head between a \startsetups.... \stopsetups (since I wanted to create a few different chapter possibilities as setups to choose from), the hashes in the above command cause an error. The error reads: You meant to type ## instead of # right?..... fatal error... Why is this? Julian
