Structureuservariable and long lines
by denis.maier＠unibe.ch 12 Mar '25

12 Mar '25

Hi, I have section headings where I need to output some descriptions after the label and before the heading title (which may be missing in some cases). I've thought the something like the example below should work, but the text from the variable overflows. What am I missing here? Is there maybe an easier way to reach that goal? Best, Denis \define[2]\sectionCMD {#1\par \structureuservariable{something}\par #2 } \setuphead [section] [ command=\sectionCMD, ] \starttext \startsection [title=Hello] [something=ajskdflö asjdfkl asjdföla asdf asdf asdf asdf asdf ksdföalks djföalskd föalskdföl asdjkfaöls djkfaölsdjf,] asdf \stopsection \stoptext

You’re invited to our regular online meet-up, this upcoming Wednesday, March 12th, 19:00 CET (UTC+1) at https://lecture.senfcall.de/hen-rbr-rku-oke (same, but shorter: https://u.mtxrun.eu/ctxmtg) 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...

Add text to endnote stream
by Rik Kabel 12 Mar '25

12 Mar '25

Hello all, Is there a better way to insert arbitrary text into the endnotes? I currently add "Chapter N+1 Endnotes" (appropriately formatted) to the last endnote for chapter N, but that would prefer to automate this and tie it to the chapter start (via setuphead/beforesection). -- Rik

Grid and setupparagraphs problem, LMTX and MkIV
by Rik Kabel 09 Mar '25

09 Mar '25

Hello experts, I am stumped trying to eliminate the extra vertical space in the following example. Can anybody point out where it is coming from and, more importantly, how to eliminate it. All lines should be on the grid, but the paragraphs environment clearly is introducing extra space (or removing it). I do note that the problem exists with MkIV and LMTX not giving the same result, but with neither setting on the grid. \setuplayout [grid=on] \showgrid \defineparagraphs[TwoCols] [n=2] \setupparagraphs[TwoCols] [each] [before=\blank[line],after=\blank[line], ] \setupparagraphs[TwoCols] [2] [width=.6\textwidth] \starttext \input dawkins\par \input dawkins\par \startTwoCols abc\nextTwoCols abc\stopTwoCols \startTwoCols abc\nextTwoCols abc\stopTwoCols \startTwoCols abc\nextTwoCols abc\stopTwoCols \input dawkins \stoptext -- Rik

How to prevent \reference[myrefA]{myrefA} from creating vertical emptiness?
by Joel 07 Mar '25

07 Mar '25

Here is my minimum working example: \startuseMPgraphic{FunnyFrame} picture p ; numeric w, h, o ; p := textext.rt(\MPstring{FunnyFrame}) ; w := OverlayWidth ; h := OverlayHeight ; o := BodyFontSize ; p := p shifted (2o,h-ypart center p) ; draw p ; drawoptions (withpen pencircle scaled 1pt withcolor black) ; draw (2o,h)--(0,h)--(0,0)--(w,0)--(w,h)--(xpart urcorner p,h) ; %draw boundingbox p ; setbounds currentpicture to unitsquare xyscaled(w,h) ; \stopuseMPgraphic \defineoverlay[FunnyFrame][\useMPgraphic{FunnyFrame}] \defineframedtext[FunnyText][frame=off,background=FunnyFrame, width=\textwidth] \def\StartFrame{\startFunnyText} \def\StopFrame {\stopFunnyText } \def\FrameTitle#1% {\setMPtext{FunnyFrame}{\hbox spread 1em{\hss\strut#1\hss}}} \setMPtext{FunnyFrame}{} \define\sidebarA{% \placefigure[none]{}{% \FrameTitle{\strut \bf Title}% \StartFrame% Text \StopFrame% }% }% \starttext \startparagraph \input knuth \stopparagraph\reference[myrefA]{myrefA} \sidebarA \startparagraph \input knuth \stopparagraph \stoptext I need to make a reference to the box, which I call a sidebar. I've put \reference[myrefA]{myrefA} near it, so a cross-reference will say "See the sidebar on p. 2". The problem is, its creating a strange vertical space. If I put it anywhere in front of \sidebarA, it makes a gap above the sidebar. And if I put it anywhere after \sidebarA, it puts the gap after. And if I put it inside, it causes some error and it lists as ?? instead of showing the page number. Note that this also happens with floats I have for pictures. The same problem is appearing! How do I get rid of the extra vertical gap that is appearing where I put my reference? --Joel

How to return 'setupalign' to default behavior after setting?
by Joel 07 Mar '25

07 Mar '25

My copyeditor asked me to adjust parts of the document to fit this: \setupalign[verytolerant, nothyphenated] \setupnotation[footnote][align={hyphenated, normal}] It is causing problems in other areas of the document, where its no so needed though. Is there a way to tell these commands to "go back to the default"? like \setupalign[default]\setupnotation[default] --Joel

How to stop column text from crashing into content afterwards?
by Joel 06 Mar '25

06 Mar '25

It took a lot of trial and error, but here's the glitch I am seeing in this minimum working example: \starttext \startcolumns[n=2] \section{Title} \input knuth \section{Title} \input knuth \section{Title} \input knuth \section{Title} \startitemize \dostepwiserecurse{1}{11}{1}{ \vbox{ \startitem Question \recurselevel \startitemize \startitem A\stopitem \startitem B\stopitem \startitem C\stopitem \startitem D\stopitem \stopitemize \stopitem } } \stopitemize \stopcolumns \section{Title} \input knuth \startcolumns[n=2] \section{Title} \input knuth \section{Title} \input knuth \section{Title} \input knuth \section{Title} \startitemize \dostepwiserecurse{1}{11}{1}{ \vbox{ \startitem Question \recurselevel \startitemize \startitem A\stopitem \startitem B\stopitem \startitem C\stopitem \startitem D\stopitem \stopitemize \stopitem } } \stopitemize \stopcolumns \section{Title} \input knuth \section{Title} \input knuth \section{Title} \input knuth \stoptext If you render it and go to page 7, you will see that the item in Question 11, choices C and D are covering up "10 Title" on the same page. In my own document, this is happening a great deal. I could use a page break, but as you see here with question 11, that would leave a huge piece of the page gone. I've even seen some cases where it seems the columns start writing over each other, instead of going to the next page. So image in this documetn if question 8, 9, and 10 appeared on topo of 5, 6, and 7. Is there any way to present this terrible behavior from rendering like this? --Joel

LMTX/LuaTeX: much bigger output size in imposition
by Pablo Rodriguez 05 Mar '25

05 Mar '25

Dear list, I create booklets with the following source: \setuppapersize[A5, landscape][A4] \setuparranging[2UP] \setuplayout[page] \setuppagenumbering[alternative=doublesided] \setupinteractionscreen[option={landscape,paper}] \starttext \def\Doc{xml-mkiv.pdf} \getfiguredimensions[\Doc] \dorecurse{\noffigurepages} {\externalfigure[\Doc][page=\recurselevel, width=\textwidth]} \stoptext In this case, I need to impose the resulting PDF file again: \setuppapersize[A5, landscape][A4] \setuparranging[2TOP] \setuplayout[page] \setuppagenumbering[alternative=doublesided] \setupinteractionscreen[option={portrait,paper}] \starttext \def\Doc{booklet.pdf} \getfiguredimensions[\Doc] \dorecurse{\noffigurepages} {\externalfigure[\Doc][page=\recurselevel, width=\textwidth] \externalfigure[\Doc][page=\recurselevel, width=\textwidth]} \stoptext Generating this second booklet (from the same PDF document), LMTX generates a resulting PDF document which is four times bigger than the one generated by LuaTeX. In fact, these are the file sizes: 1.2M Mar 4 18:38 xmlpdf-lmtx.pdf 321K Mar 4 18:41 xmlpdf-luatex.pdf It seems as LMTX was (almost) disabling PDF compression on the second imposition. Would anyone be so kind to confirm this issue? Many thanks for your help, Pablo

by Taco Hoekwater 05 Mar '25

05 Mar '25

Hi all, Today, Wednesday 5 March we will be upgrading the operating system software of the NTG/ConTeXt Group web server. Starting at 1pm local time services like this and other ntg.nl and contextgarden.net mailing lists, the ConTeXt wiki, and the NTG and ConTeXt Group websites will be offline for a (hopefully short) period. Komende woensdag 5 maart gaan we de besturingssysteem software van de NTG/ConTeXt Group webserver upgraden. Vanaf 13:00 uur lokale tijd zijn diensten als deze en andere ntg.nl en contextgarden.net mailinglijsten, de ConTeXt wiki en de NTG en ConTeXt Group websites voor een (hopelijk korte) periode offline. Best wishes, Taco
