How to stop lists from being double-spaced?

05 Apr '25

When I set items in a list, like this: \starttext\startitemize[n]\startitem \input knuth \stopitem\startitem \input knuth \stopitem\stopitemize\stoptext ...it ends up placing the items in double-space, or similar, where there's about a gap of one text-height between lines, instead ofthe usual gap between lines. If you render the above, it makes a gap between the two quotes. Is there a way to make it have normal line width? --Joel

pdfuaid metadata info not added to xmp

Hans, compiling the following source: \setupbackend[format=pdf/ua-2] \setuptagging[state=start] \setupstructure[state=start] \setupbackend [format=PDF/A-3a, intent=sRGB IEC61966-2.1, level=0] \setupexternalfigures[location=default] \starttext \externalfigure[cow][label={this is a cow}] \stoptext I’m afraid that veraPDF warns about ua-1 missing metadata info (https://github.com/veraPDF/veraPDF-validation-profiles/wiki/PDFUA-Part-1-ru…) This should be the reason why veraPDF cannot autodetect that the output from the sample above is PDF/UA-2 (althought it passes this validation profile when specified). I see that lines 600 to 750 from lpdf-fmt.lmt include these metadata (even with WTPDF-1.0 accesibility and reuse), but somehow they don’t end up in the output PDF document. Could you take a look at this? Many thanks for your help, Pablo

update
by Hans Hagen 04 Apr '25

04 Apr '25

We pushed the first post texlive 2025 update. Apart from a few pending patches, we spend some time on what we call retrotex and retropost. retrotex: Due to external factors the decision was made to let luatex math default to a more conservative handling of fonts: we just assume that opentype fonts are implemented like traditional tex fonts. This makes math in the engine behave like xetex. The primitives that relate to controling some aspects of math rendering are obsolete (we also removed experimental additional italics mode code). This change doesn't affect ConTeXt (MkIV) because there we do things differently. The adapted engine will be used in texlive 2026 (but we already have it in the distribution). retropost: We had to spend some time on fixing a bug in the mp library, one that was introduced when the additional number models were implemented and that surfaced when testing files of a power user. It was a rather nasty one that only showed up when using equations with no viable solution. In the process we (MS and HH) had to consult the metafont books, because we basically had to check all relevant code, and then fell in love with bitmaps. That made us decide to bring back bitmaps in the mp engine even if it sounds somewhat going back in time. We actually had some other reasons but those will be revealed at the meeting. tariffs: Talking of the ctx meeting, we might have to make some decisions there. A recent post on the list indicated that some installations default to letter size paper format, which one canconsider a bad idea but let's put that aside. The fact that installations can adapt that way, makes that we can also implement a tex tariffs system (tts) in accordance with current and upcoming European guidelines. For instance we can make context run 25 percent slower when the main language is us-english or 50 percent when fonts originating at (spineless) big tech companies are used. It's not that hard to do this (via directives). We assume that at some point tex installations used in the usa have to provide similar means but we leave that to those responsible for the distributions. After all, they already have to deal with excluding files that show traces of support for commercial fonts. At the meeting we might also decide to default to Canadian English patterns or those used in GB. And who knows if and when we're forced to (or feel that we have to) remove software components from the engine that relate too much to big tech or come with unacceptable demands for conformance. The good news here is that we have no dependencies that can't be overcome. Maybe we should also support the euro as math marker or just ditch the dollar for that purpose. Mixed in with preparations for the upcoming BT we will come back to some issues reported on the list. We've been a bit silent for various reasons but Wolfgang made sure all went well which feels good.

nested context/lua calls
by Mohammad Hossein Bateni 03 Apr '25

03 Apr '25

Hello, I have some code like this: --------------------------------- \def\MakeSomething{... some code that returns number 12} \startluacode function WorkWithSomething(data) -- call MakeSomething to obtain 12 -- base on the value above make some decisions end WorkWithSomething(some_data) \stopluacode --------------------------------- If I use context.MakeSomething() inside the lua block, this is buffered till the end of the block, so I can't get the result and work with it. If MakeSomething is a command already "edef-ed", I can use tokens.getters.macro.MakeSomething to find the value. If MakeSomething has an argument which is determined within the lua block, then I can't use this hack. The ugly partial solution I have found is to change the signature of WorkWithSomething to receive an argument and then I replicate the parameters of MakeSomething on the TeX side: --------------------------------- \def\MakeSomething#1{...} \startluacode function WorkWithSomething(data,MakeSomethingOutput) -- we wanted to use some computation on data to obtain input to MakeSomething -- then call MakeSomething to obtain its result end \stopluacode \ctxlua{WorkWithSomething(some_data, "\MakeSomething{replicate processing on data to obtain input to this macro}")} --------------------------------- Is there a more elegant solution? Ideally I want a way to start a TeX process under Lua, and process the macros there before I get to the next line of Lua code. In my motivation, MakeSomething is \datasetvariable. I wanted to look up something in the dataset and use it for the rest of computation/typesetting. Thanks a lot, --Mohammad

How to get TABLE to start on the same page, split when needed?
by Joel 02 Apr '25

02 Apr '25

I was using tabulate, but ended up with some strange error I could not track down. So I switched to using TABLE, the error went away, but now I have a new problem: If the TABLE is really big, but fits on the next page, it seems to add a \pagebreak before, then shows the table. This is wasting way too much paper, it means I have instructions, then the activity appears on the entirely next page, with a big unneeded blank space given. I need the table to start, then split whenever the end of the page is reached. In the wiki, I found this comment from 2021: "Beware: Split tables often begin not on the page (or in the column, if you use them) where they could start, but on/in the next one.This is a known limitation due to the complicated calculation of remaining space on the page." Is this still an error in TABLE, or is there a fix? --Joel

wrong compressmethod=separator as stopper too?
by Pablo Rodriguez 28 Mar '25

28 Mar '25

Dear list, I have the following sample: \setuppapersize[A7] \setuplinenote[paragraph=yes, compressmethod=separator, compress=yes, compressseparator={\|\|}] \starttext \dorecurse{25} {a\linenote{b} } \stoptext The || separator is also used as a stopper. As far as I understood (and ConTeXt behaved like that last time I used this feature) the separator command replaces the repeated line number. It should not be used as an stopper (or to mark the separation with next line). Could anyone be so kind to confirm that this is unintended and that I’m not missing anything?

mathmatrix: Aligning row baseline to text baseline
by Kirill Davidov 27 Mar '25

27 Mar '25

Greetings, This is little more than a pet peeve of mine, but the `location=normal` option for `mathmatrix` has the matrix's center row baseline misaligned with the baseline of the math around. The severity of the misalignment seems to correlate with interline space settings — more space, worse the misalignment. Is it possible to align the baselines? I've been spoiled by LaTeX's `tabularray` package — it has an undocumented value for its `baseline` key. Setting it to `M` does exactly what I want. This MWE demonstrates the misalignment with a double line spacing: % start MWE \setupinterlinespace[line=5.6ex] \startdocument \startformula \showboxes = \matrix{=} \stopformula \stopdocument % stop MWE Kirill

footnotes with separate lines
by jbf 27 Mar '25

27 Mar '25

I am wondering if there is a solution to the problem I have just encountered. I have a footnote that requires separate lines. I have achieved that in a straightforward case as follows: \footnote{1770 – the discovery\\ 1778 – the invasion\\ 1824 – the war of extermination\\ 1901 – the Constitution} That works, but if I add \setupinteraction[state=start] to the file it does not. That particular footnote causes the compilation to go into an endless loop. All other footnotes are ok. I tried replacing the \\ with \crlf but that has the same result. I tried \start...\stoplines in the hope that this might work inside a footnote, but it doesn't. Of course, I do not understand what is happening between 'interaction' and what I am doing with this particular footnote, but clearly it is problematic. Any way I can get my separate lines and still have interaction working in that file? Julian

Dear list, I have the following sample: \setuppapersize[A7] \starttext \definecolumnset [paral] [n=2] \definesubcolumnset[paral][1][1] \definesubcolumnset[paral][2][2] \startcolumnset[paral] \startsubcolumnset[1] abce \stopsubcolumnset \startsubcolumnset[2] abcd \stopsubcolumnset \flushsubcolumnsets[spread] \startsubcolumnset[1] abc% \inframed [background=color, backgroundcolor=lightgreen, frame=off] {e} \stopsubcolumnset \startsubcolumnset[2] abc% \inframed [background=color, backgroundcolor=lightred, frame=off] {d} \stopsubcolumnset \flushsubcolumnsets[spread] \stopcolumnset \stoptext What I want to achieve is automatic text comparison between versions of the same text (in different subcolumnsets). The first line shows different versions text. I wonder whether there would be an automatic way to get the \inframed highlighting with any character that differs from the other column (it might be different, or just missing or being added). I think this may be possible with ConTeXt, but I don’t know how to achieve it automagically. Any ideas on how to get this automatic text comparison? Many thanks in advance, Pablo

Dear List, Me again, I have a question to this formula. I want to use 0.222 222 222_3, but I get 0.222222222_3. And another question too: how can I say, that I want not so much place between formula lines? \setuppapersize[A4] \setupbodyfont[thermes, 8pt] \starttext \startformula x_1 = 0.222 222 222_3 \stopformula \stoptext I want to have \startformula x_1= 0.222 222 222 x_1=0.222 222 222 \stopformula , but not \startformula a=b a=b \stopformula Many thanks for your help and tips.

Problem with Named setuplayout
by Jethro Djan 25 Mar '25

25 Mar '25

Dear list, There seems to be a problem with setuplayout[name][ .. = ..]. I got this problem when I updated to the newest version. MWE: \setuplayout[examFirstPage][ topspace=7mm, top=5mm, header=10pt, headerdistance=2pt, height=280mm, width=160mm, margin=20mm, footerdistance=0pt, footer=0pt, ] \definemakeup[examFirstPage][ pagestate=start, footerstate=start, top=, ] \starttext Hello \stoptext When I remove "[examFirstPage]', it works fine. Has a change been introduced about how to use it this way? Yours sincerely, Jethro

Problem with \reference and \at
by Ursula Hermann 24 Mar '25

24 Mar '25

Dear List, If I compile the following example, \usecolors[svg] \setupinteraction [state=start, contrastcolor=cornflowerblue] \reference[other]{Seite 33} \it Hinweis: Beachten Sie die Konvention aus \at{Seite 33}[other] die Formuloierung. The Link is here, but I get : Seite 33 1. What can I do, to not have the 1, after the page Number? Cause If I try the same example, but use \goto, then it works, but I wanted the page number. Many Thanks Uschi

Problem with \reference and \at. Sorry, forgot \starttext, and \stoptext
by Ursula Hermann 24 Mar '25

24 Mar '25

Dear List, I am sorry, I forgot \starttext and \stoptext in the example. The problem is, that after Seite 33, there is also the Number 1, I do not want to use. \usecolors[svg] \setupinteraction [state=start, contrastcolor=cornflowerblue] \starttext \reference[other]{Seite 33} \it Hinweis: Beachten Sie die Konvention aus \at{Seite 33}[other] die Formulierung. \stoptext What is wrong here? Many thanks Uschi

Problem with JPEG2000 inclusion in 2025.02.28 update
by Jim 23 Mar '25

23 Mar '25

I use JPEG2000 images and, unit the most recent update, these worked fine for me (i.e., anywhere a "normal" JPEG could be included, a JPEG2000 could be included). This seems to have come to a crashing halt with the 2025.02.28 update. Now I just get the gray box. Here is an example of it not working (I have attached a .JP2 image of ConTeXt's favourite cow): %%%% begin here \setupexternalfigures[location={local,default}] \starttext \line{% \externalfigure[cow.pdf][height=1in]% \hss \externalfigure[cow-jp2.jp2][height=1in]} \stoptext %%%% end here I get the same problem with .JPX (JPEG2000 Part 2) images (which are the ones I really want to use). This is a show-stopper for the document I produce. Can anyone suggest either (a) a workaround so that I can include JPEG2000 images (aside from converting them to JPEGs and including those), or (b) tell me how I can revert to the previous version of ConTeXt? (Unfortunately, my web search for installing an older version is polluted by mostly non-ConTeXt uses of the word "context".) Thanks. Jim

help with \flushsubcolumnsets[spread]
by Pablo Rodriguez 23 Mar '25

23 Mar '25

Dear list, first of all, sorry for not providing a MWE, but it is really hard in this case. To enjoy the new added abilities for parallel texts in ConTeXt, I’m making a six-language version of an ancient Greek text. Columns setup (using landscape A4), so there are two pages: \definecolumnset [parallel] [n=3, align={lesswidows,lessclubs,lessbroken,lessorphans}, ] All works fine, but I have a single passage that has problems. It’s a chapter with title and two lines of text (in original Greek) and title and three/four lines of translation. Chapter setup reads (for the relevant parts): \setuphead[chapter] [before={\blank[none, preference]\testcolumn[5]}, after={\blank[none, samepage]}] Well, the problem is that only the Greek text appears at the end of the first page (no translation is shown at the end of the first or second page), and all translations appear at the beginning of the third and fourth page (no Greek text at the beginning of the third page). How can I make that ConTeXt prioritizes leaving one (or two) orphan line(s), but flushes that Greek text and the five translations? Many thanks for your help, Pablo

How to span an image across two pages with a caption?
by Joel 22 Mar '25

22 Mar '25

I am trying to do this, basically my document has some floats, with captions, that appear within the text, but occasionally, I want some special images to be rendered across the full page (left and right). The text of the chapter should appear on the pages before this and after it, but not on the page with these images. And the page number/headings shouldn't appear. Ideally the caption just is displayed bottom left, on the left-side / verso page. Is there a simple way to achieve that? I found and modified this code on-line, which it works well, but it isn't flexible, in that my document might have 20 more such images, and this way that its defined means a lot of redundant code used: %%% Full-Page Graphics \unprotect \useexternalfigure [railroad] [P1976-48-33b] [ width=2\paperwidth, height=\paperheight, ] \newcount\railcount \def\pickhalfrail_cmd{% \setupclipping [nx=2,ny=1]% \ifnum\railcount>0 \ifodd\pagenumber %% clip right half \clip[x=2,y=1] \else %% clip left half \clip[x=1,y=1] \fi{\externalfigure[railroad]}% \global \advance \railcount \minusone \fi% } \defineoverlay [pickhalfrail] [\pickhalfrail_cmd] \setupbackgrounds [paper] [background=pickhalfrail] \def\railbackgrounds{% \pagebreak \null \pagebreak \global\railcount=2 \page[imagetopagebreak] \null \page[imagetopagebreak] \null \page[imagetopagebreak] \null } %% Adjust page style to hide text when images appear \definepagebreak[imagetopagebreak][yes,header,footer]
