Why the way key-value argument is called affected the document's output?

Hi, I was cleaning and formatting my context file and then when I compiled it, the output I got introduced extra vertical spacings at the section headings that weren't there in the previous compilations. I had to spend enormous amount of time trying to fix it so to emulate my previous outputs. Turns out the problem was how I called one of the key-value argument in the document. I really wanna know the reason why it did influenced the output? Provided below is the minimal source code (and it is producing different outputs, meaning the vertical spacings are not same, on my device running the version released in the September and also tested with the latest release.) """ %% differences in outputs, for how "grid=yes" is called. %% Type 1. %\setuplayout[grid=yes] %% Type 2. %\setuplayout[ %grid=yes %] \setuphead[section][grid=low] %% needed to observe the output difference \starttext \title{Alpha} \subsection{Beta} \input{knuth} \stoptext """ Best regards, Ali

Asking help for better way to make tickets.
by Jeong Dal 13 Jan '24

Dear all, I’d like to make a ticket on A4 as follows: 1. Use all of A4(no margin, no header, no footer,…) 2. Arange 12 tickets in the form of 3 x 4 on one page, 3. Two rows are same, 4. Numbers in the center of the ticket which is increasing. I use the following code to make it. but I think that there is a better and simpler way to do it which I don’t know. I hope that someone give me a nicer way to do it. Thank you for reading. Best regards, Dalyoung \setuppapersize[A4]%[A4] \setuplayout[ width=210mm, height=297mm, topspace=0pt, backspace=0pt, header=0mm, footer=0mm, margin=0mm, bottomspace=0mm ] \startuseMPgraphic{ticket}{i,j} path p,q; pair A,B; p := unitsquare xyscaled (67mm,73mm); A := point 0.5 of p; B := point 2.5 of p; draw p; label(textext("Text"), .25A+.75B ); label(textext("\tfd " & decimal (3*\MPvar{i}-\MPvar{j})), center p); label(textext("Text"), .75A + .25B); \stopuseMPgraphic \starttext \dorecurse{4}{ \startcombination[3*1]%distance=0mm] {\useMPgraphic{ticket}{i=\recurselevel,j=2}}{} {\useMPgraphic{ticket}{i=\recurselevel,j=1}}{} {\useMPgraphic{ticket}{i=\recurselevel,j=0}}{} \stopcombination \startcombination[3*1]%distance=0mm] {\useMPgraphic{ticket}{i=\recurselevel,j=2}}{} {\useMPgraphic{ticket}{i=\recurselevel,j=1}}{} {\useMPgraphic{ticket}{i=\recurselevel,j=0}}{} \stopcombination } \page \dostepwiserecurse{5}{8}{1}{ \startcombination[3*1]%distance=0mm] {\useMPgraphic{ticket}{i=\recurselevel,j=2}}{} {\useMPgraphic{ticket}{i=\recurselevel,j=1}}{} {\useMPgraphic{ticket}{i=\recurselevel,j=0}}{} \stopcombination \startcombination[3*1]%distance=0mm] {\useMPgraphic{ticket}{i=\recurselevel,j=2}}{} {\useMPgraphic{ticket}{i=\recurselevel,j=1}}{} {\useMPgraphic{ticket}{i=\recurselevel,j=0}}{} \stopcombination } \stoptext

The code for registers does that translation -- from an arbitrary realpage of your document to the corresponding user page number, with the right formatting -- but I could not find the code that does that in strc-reg.* source files.

Re: LMTX schema for poster

It's not clear whether the intersecting boxes are simply decorative or meant to present some sort of logical structure. I'm happy for it to be decorative, in which case fewer labels might be better.

Consider swapping the TeX and MetaPost circles so that Lua, MetaPost and TeX are read left to right as they appear in the acronym LMTX. Perhaps invert the "triangle" so that there are two circles at the top. My first idea was to show that TeX and MP are under Lua control, but Hans disagreed. So while the 3 subsystems interact, I wanted to keep TeX on top. > 7.

Use the Christmas card code / memory game code to produce patterns to use as the dots in the QR code? If the QR is large enough for people to distinguish the individual dots then it would provide a talking point? Or maybe have a copy of the card game to hand and challenge them to find a randomly drawn card in the QR code? I don’t think I understand your intention. I wouldn’t construct a QR code out of other stuff, it would become too big. Hraban

Chemnitz, Leipzig, Call for Poster
by Henning Hraban Ramm 11 Jan '24

11 Jan '24

Hi folks, in March, there’ll be Linux Days in Chemnitz/Germany (Chemnitzer Linuxtage, https://chemnitzer.linux-tage.de/2024/en/) an OSS fair. DANTE usually has a booth there, and this time I’ll help. I’d like to have a poster that shows off ConTeXt/MetaFun features. Do you have suggestions or (even better) would you like to create it? It would be nice to have for further events (last year I presented ConTeXt at FrOSCon and CCCamp and lacked a poster). In the following week and nearby, there’s Leipzig book fair (including Manga-Comic-Con), https://www.leipziger-buchmesse.de/ It’s always a great experience! Our little publishing house will have a booth again (full of books made with ConTeXt) – please visit me, if you come! Hraban

Status of Asymptote
by Alexandre Christe 10 Jan '24

10 Jan '24

Dear all, I'd like to know what is the status of Asymptote in Context. To my knowledge, metapost/metafun only support 2D (except with the additional libraries from Roegel, which would have to be cleaned up a bit). Otherwise, what shall be used for 3D drawings in Context? TikZ? Something else? Thanks in advance. Alex

A happy & healthy new year! You’re invited to the first online meet-up of the year, this upcoming Wednesday, January 10th, 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 every time:) [Howto] * No special software installation required; most modern browsers should work (WebRTC required). * Open the above URL, 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, e.g. 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/teachers/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...

Width of captions and notes in outer margin not correct on even pages
by Milan cel Mare 09 Jan '24

09 Jan '24

Hi, I have observed that the widths of captions and also notes on even pages is not as I would expect them to be. Reading through the documentation I figured out that the width for captions has to be set manually when they are placed in the outer margin. I did so by setting it to width=\outermarginwidth. But it seems that for captions the width is derived from the inner margin width on even pages. The width of notes in the outer margin placed with \inouter is also off on even pages. They are too narrow and do not "fill" the available space (things seems to work for notes in inner margins though). Here is an example: \setuppapersize[A4] \setuplayout[backspace=40mm, width=100mm, leftmargindistance=5mm, leftmargin=30mm, rightmargindistance=5mm, rightmargin=50mm, topspace=10mm] \setuppagenumbering[alternative=doublesided] \setupcaptions[location={outermargin, low}, width=\outermarginwidth, headcolor=red, color=green, style={\tfx\setupinterlinespace}, align=width] \setupexternalfigures[location=default] \setupmargindata[style={\tfx}, stack=yes] \setupmargindata[inouter][color=orange] \setupmargindata[ininner][color=blue] \showframe \starttext \section{Margin Tests} \input knuth Some more stuff\inouter{Some multi-line text to be placed in the outer margin to check whether it is positioned correctly.} to read\inouter{Another multi-line text to be placed in the outer margin to check whether it is positioned correctly.}. \startplacefigure[title={A lengthy caption perfectly suited to perform some tests, which cause lines to wrap.}] {\externalfigure[cow][maxwidth=80mm]} \stopplacefigure More stuff\ininner{A1, A2, A3, A4 are well-known paper formats used in Europe and in some other places.}. \input zapf Some more stuff\inouter{Some multi-line text to be placed in the outer margin to check whether it is positioned correctly.} to read. \startplacefigure[title=A SVG test with a long caption to cause line wraps.] {\externalfigure[cow][maxwidth=70mm]} \stopplacefigure More stuff\ininner{A1, A2, A3, A4 are well-known paper formats used in Europe and in some other places.} to read. \input knuth \stoptext As a workaround the width for captions can be set to width=\rightmarginwidth, but how can I solve the issue with the notes? I am running ConteXt 2023.09.26 18:19 on Windows 10. Thanks and best regards Milan
