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

comparing text with the new typo-dif.mkxl
by Pablo Rodriguez 11 May '25

11 May '25

Hi Hans, from typo-dif.mkxl, lines 16-17: > % Currently only a color can be set but I might add support for underline > % and simple background. Would it be possible to have simple (color) background implemented? After comparing texts, I realize that when few chars differ (or even only one), it is harder to notice. Colored background (with even white foreground color) is far easier to notice. Many thanks for your help, Pablo

List of abbreviations
by Jeroen 10 May '25

10 May '25

At the beginning of a report I would like to have a page with an abbreviation listing with for example HTML hypertext mark-up language CSS cascade style sheets etc The distancing where the long explanation starts should be the same at lets say 30mm from the margin and in case it jumps to a next line, it also should continue at 30mm from the margin and not back at the margin. What would be the best way to achieve this? Thanks Jeroen

\ifnum with two \recurselevel
by Pablo Rodriguez 09 May '25

09 May '25

Dear list, I have the following sample code: \starttext \startTEXpage[offset=1dk] \dostepwiserecurse{2}{6}{1}{\edef\AbC{\recurselevel}% \dostepwiserecurse{2}{7}{1}{%\AbC.\recurselevel\ /\ \ifnum\AbC < \recurselevel% \AbC:\recurselevel\ \|\| \fi} \\} \stopTEXpage \stoptext I would like to only get the numbers in the form first:second loops if and only if the value of the first loop is less than the value from the second loop. I think this should be simple, but I don’t get it with any of these conditionals: \ifnum\AbC < \recurselevel \ifnum\recurselevel > \AbC Sorry for the stupid question, but what I am missing here? Many thanks for your help, Pablo

modernizing
by Hans Hagen 08 May '25

08 May '25

Hi, At last week bachotex we (Tove, Mikael, Willi, Hans) cinducted the first in a series of experiments and presentations dealing with accessibility. After all, why bother more about pdf than of the tool that makes it. - we tested if qr codes were easier on users than tex error messages (experiment conducted with high end wooden ear-tags with qr codes made by Willi, who else) because after all humans are good in pattern recognition - we (read: Tove, well known from the "ts" unit) tested to what extend colors could be recognized (after all in Sweden PDF documents have to obey very strict rules wrt color); we will report later on this promissing "flagged pdf" (with color light bulbs triggered by pdf) experiment in an article - as side track (okay: logical follow up) we checked how users react on more vivid visual feedback (this is already supported but the manual was on purpose not yet added to the distribution); we will follow up on this at the context meeting You can do part of this experiment by adding this to the top of your file: % signal=qr (There's also a command line option plus a related script. The next upload will have the preliminary "signals.pdf" manual, just in case you have the needed equipment.) In that case an error will pop up a qr code. The idea is that after while you (or your mobile phone) will recognize these messages easier than parsing a log. It also fits more in todays paradigms. We might eplore easy installations with qr codes because after all that's how things are done these days. So, thanks to Tove, we ended up in modern times.

Hi, we just saw the Accessibility Directive, now there is another demand: the TDM protocol (concerning the reuse of protected works for AI training purposes). Is it possible to implement these TDM Metadata when producing PDF files with ConTeXt? This technique provides a way to embed the rightsholder's choice into a PDF file. (See «§6.6 TDM Metadata in PDF files»: https://www.w3.org/community/reports/tdmrep/CG-FINAL-tdmrep-20240510/#sec-p…) Steffen

cannot find fonts in a manual install; what did I miss
by damien＠thiriet.web4me.fr 30 Apr '25

30 Apr '25

Hello! Since OpenBSD has upgraded to 7.7, I performed a manual installation of LMTX standalone after upgrading to my new OS version. What I did: download cont-lmt.zip into /usr/local/context/tex/texmf-context/ mv /home/dthiriet/cont-lmt.zip . unzip cont-lmt.zip cd source/luametatex/ ./build.sh (ou si ça ne marche pas pour des raisons d’autorisation: sh build.sh) cp build/native/luametatex tex/texmf-openbsd-amd64/bin/ depuis $HOME mtxrun --generate mtxrun --script fonts --reload Everything compiles, but the fonts are not found: fonts > defining > font with asked name 'lmsans10-regular' is not found using lookup 'file' fonts > defining > unable to define 'lmsans10-regular' as 'modern-12pt-ss-tf-' fonts > defining > forced type 'otf' of 'latinmodern-math' not found fonts > defining > unable to define 'latinmodern-math.otf' as 'modern-12pt-mm-mr-' fonts > defining > unable to define 'latinmodern-math.otf' as 'modern-12pt-mm-mb-' fonts > 'fallback modern ss 12pt' is loaded When I search my texmf-context file, I cannot find these otf files, so the problem isn't that I put them in the wrong place. I compared with my previous context install, and I can see the difference is that in the former my tree looked like this /usr/local/context | |-- texmf-context/ |-- texmf-openbsd-amd64/ |-- texmf This texmf/ folder, which contains fonts/ (with lmodern otf files and so on) and web2c misses in my current tree. But the context-readme.txt AFAIU does not say anything about a texmf/ folder in the tree. What did I miss? Should I have downloaded another zip from pragma pages? Thanks, Damien

How to easily comment out/uncomment multiple lines all at once?
by Joel 27 Apr '25

27 Apr '25

I have a single *.tex file that I have setup, here's a simple minimal example: \define\macroA{This outputs some stuff.} \define\macroB{\input knuth } \define\macroC{This outputs other stuff.} \define\macroD{This outputs other stuff.} \define\macroE{This outputs other stuff.} \define[2]\macroF{This is text #1 and #2.} \define\macroG{This outputs other stuff.} \define\macroH{This outputs other stuff.} \starttext \macroA%\macroB%\macroC%\macroD%\macroE %%% some more code \macroF{a}{b}\macroG\macroH \stoptext Normally, I will compile it as above, so only two of the macros actually appear. But sometimes, for testing purposes, I want to make sure my code is functioning good, so I will go an un-comment all of the macros, and then compile, and it basically does a test, making sure all of the macros in my code function perfectly. When testing, it looks like this: \starttext \macroA\macroB\macroC\macroD\macroE %%% some more code \macroF{a}{b}\macroG\macroH \stoptext Because the actual file is quite large, commenting and un-commenting the lines takes a long time, and can lead to mistakes. Is there any simpler way to easily switch between the two versions? --Joel

How to force end-of-sentence space?
by Joel 27 Apr '25

27 Apr '25

When I have a word like "U.S." in a sentence, I'm using code like this: After the U.S.\ Army left Vietnam, they focused on... ...that seems to make sure the space between U.S. Army isn't so big. My copy editor noticed that when I use footnote, there isn't the right space after, like. Here is a sentence.\footnote{This is footnote text.} This is another sentence. They are saying that after that, the space isn't the right size. Is there something similar to the first option that makes sure a full end-of-sentence space width appears? --Joel
