fittingpage dimensions
by Thangalin 15 May '25

15 May '25

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. For the next sixty seconds, this station will conduct a test of the Emergency Broadcast System. This is only a test. The broadcasters of your area in voluntary cooperation with the FCC and other authorities have developed this system to keep you informed in the event of an emergency.

This concludes this test of the Emergency Broadcast System. \stopbuffer \setupcolumns[n=2, balance=yes] \starttext \placecontent \startchapter[title={January}] \startcolumns \startitemize \dorecurse{13}{ \startframedtextitem \getbuffer \stopframedtextitem} \stopitemize \stopcolumns \stopchapter \stoptext

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

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

Typical font size and interline space for Adobe Garamond Premier Pro.
by Pawel Urbanski 13 May '25

13 May '25

Hi Everyone, Adobe Garamond Premier Pro is a very popular font. Understanding that typesetting is both art and science it is not easy to find some neat guidelines on values for size and spacing for this particular font. There are threads on the web that mostly relate to self-publishing with regular text editors. I'm currently drafting a book using the 5.5x8.5 trim size, with typical outer margins of 0.5 inch and the inner one of 0.75 (including the gutter). Would you mind sharing the values for font size and any spacing adjustment for Garamond Premier? I am currently using 11.5pt for font size, and adjust spacing from the default 2.8ex to 2.9ex. Using whitespace between paragraphs set to small, in addition to the former values. It gives me roughly 35...36 lines per page. Thank you for your answers... Pawel

The showlayout command output is missing cutspace value.
by Pawel Urbanski 13 May '25

13 May '25

Hi Everyone, I've noticed one thing while tweaking my layout. Namely, the \showlayout command output is missing the value for the cutspace. The values for margins, text area, and backspace is listed, but the mentioned cutspace. The documentation says that cutspace is equal to backspace when cutspace is equal to zero. We can obviously set it to the desired value. Listing it in the output would be useful and complete the values for layout keys when debugging. Sending it as a possible thing to consider. All the best, Pawel

How to force indents to always appear, even after figure?
by Joel 13 May '25

13 May '25

\starttext \setupindenting[yes, big, always] \input knuth \placefigure{...}{% \externalfigure[cow][frame=on, width=.6666\textwidth]% }% \input knuth \stoptext With the code above, you will notice that after the figure is placed, the next paragraph no longer gets an indent. My copy editor has warned that because my target audience is children, this will confuse them, so I need to make sure the start of a new paragraph always has an indent. I tried adding the 'always' detail to \setupindenting, see above, but that didn't help. What setting will make sure the start of my paragraph always gets an indent? Note, in my passage, I've marked every single paragraph with \startparagraph and \stopparagraph. --Joel

bytemap problem
by Keith McKay 11 May '25

11 May '25

Hi all, I've been playing with bytemaps (see the latest LuaMetaFun manual) and I have come across a problem when I create more than 15 bytemaps. This came about as part of a bigger project where I create a large bytemap and then make smaller bytemaps with the data from the large bytemap. I've made a MWE below %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% \startMPpage i := 1; for x = 1 upto 5: for y := 1 upto 5: newbytemap i of (250,250,3); setbytemap i to (floor(uniformdeviate(255) + 1),floor(uniformdeviate(255) + 1),floor(uniformdeviate(255) + 1)); fill unitsquare xyscaled (250,250) shifted ((x) * 255, (y) *255) withbytemap i; i := i + 1; endfor; endfor; \stopMPpage %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% The MWE above is for a 5 X 5 grid of randomly generated colours and you can see that the last 10m squares are black. Changing x or y to 3 will give 15 coloured squares, but a 4 X 4 grid and above gives black squares above 15 coloured squares. I can't see anything wrong with the code so I'm wondering if it is a bug. Any advice would be gratefully received. I'm running the latest update on a mac mini M1. Thanks Best Wishes Keith

Images and Accessibility (ConTeXt LMTX 2025.04.28)
by Matthias Weber 11 May '25

11 May '25

Dear All, I am starting a new thread as requested. I can confirm that > > the following should work with current latest (from yesterday, > LuaMetaTeX 2.11.07 20250427 + ConTeXt LMTX 2025.04.28 14:29): > > \enabledirectives [backend.usetags=testing] > \setuptagging[state=start] > \setupstructure[state=start] > \setupbackend > [format=PDF/A-3a] > \setupbackend[format=pdf/ua-1] > \setupexternalfigures[location=default] > \starttext > \externalfigure[hacker][label={this is an image}] > > \startparagraph > a > \stopparagraph > \stoptext produces a PDF that passes the accessibility check in the current Adobe Acrobat. In particular, it passes the alternate text checks. Hovering over the image shows the alternate text in Acrobat. However, VoiceOver (on the Mac) does not read the alternate text; it completely ignores the existence of the image. In Preview, no alternate text is shown or read. So it seems that the only benefit is that readers with vision can see an alternate text... I don’t have access to a Windows machine, so I cannot test what other screen readers can do with this document. Thanks, Matthias
