externalimage alignment inside frame changed from previous context version
by chindea.daniel＠gmail.com 15 Feb '25

15 Feb '25

Hello, I need your help. I just upgraded context. The chapter def below used to produce perfect centered number, image and chapter text. Now the image is slightly moved to the right (a divider 42mm wide by 2.5mm height). What can i do? Please help. Thank you for your great great amazin job with context. \startsetups [chapter:before] \doifoddpageelse {}{\noheaderandfooterlines} \stopsetups \define[2]\mychapter {\noindentation\strut\framed[frame=off,width=\textwidth,align=middle,location=top,frameoffset=0pt] {\noindentation\startalignment[middle]\tfd{\color[lightgrey]{#1}}\\\dontleavehmode\externalfigure[divider.pdf][width=42mm]\\\tfb{#2}\stopalignment} } %----------chapter \setuphead[chapter] [% command=\mychapter, style=\tfb, align={middle,nothyphenated}, before={% \setups[chapter:before] \blank[\measure{beforeheightbig},force] }, after={\blank[3*big]\doif{\getvariable{book}{letrine}}{true}{\placeinitial}}% ]

Problem with LMTX and heading with alternative=margintext
by Rik Kabel 14 Feb '25

14 Feb '25

The following example produces the expected result under --luatex. It hyphenates the long word and positions the chapter number within the frame. Under LMTX, the long word is not hyphenated and the chapter number is shifted out of the frame. \setuphead [chapter][alternative=margintext] \starttext \chapter {Establishment} \input klein \contextversion \stoptext The problem goes back at least to version 20240621 (running on https://www.context-on-web.eu/) I did not experiment with other mechanisms that place text into the margin. -- Rik

prevent a kind of heading at the bottom of the page
by Thomas Meyer 14 Feb '25

14 Feb '25

Hi folks, once again I have a problem - I'm sure it's not one for you experts! I've set up a diary that basically looks like this: \mainlanguage[de] \definebodyfontenvironment[12pt][interlinespace=15pt] \setuppagenumbering[location={footer,middle}, alternative=onesided] \setuplayout[ lines=44, grid=yes, ] \showgrid \startluacode function userdata.Ddate(str) local year = string.sub(str,1,4) local month = string.sub(str,5,6) local day = string.sub(str,7,8) context.date({d=day,m=month,y=year},{"weekday,{, },day,{. },month,space,year"}) end \stopluacode \def\DDate#1{\blank\noindentation{\bf\ss\ctxlua{userdata.Ddate("#1")}}\\ } \starttext \DDate{20250101} \samplefile{knuth} \DDate{20250102} \samplefile{knuth} \DDate{20250103} \samplefile{knuth} ... \stoptext But if the DDate line is moved to the bottom of the page, it is not moved to the next page above the text like a heading. The date line should therefore function like a heading. If I move it via \subject{\DDate{20250101}} the font size is of course no longer correct and I have blank lines underneath. Please help me with this. Greetings Thomas

setting the space after a figure
by mf 13 Feb '25

13 Feb '25

Hello, I want to set to space between a figure (float) and the main text. I thought this worked: \setupfloat[figure][spaceafter=2cm] but it does not, while this: \setupfloat[spaceafter=2cm] works, but -- I suppose -- it does effect every float, not just figures. Here's a MWE to test it: -------------------------------------- % the next setting is consistent with my real case \setupcaption[location=top] % this works % \setupfloat[spaceafter=2cm] % this does not work \setupfloat[figure][spaceafter=2cm] \starttext \dorecurse{3}{\samplefile{lorem}\par} \placefigure[here]{}{\framed[width=\hsize,height=5cm]{}} \dorecurse{4}{\samplefile{lorem}\par} \stoptext -------------------------------------- Massi

[ drawing lines with metafun ]
by vm 12 Feb '25

12 Feb '25

is it possible when using metafun, given a path to rotate the pen orientation following a different path? e.g. rotating the pen while drawing a line? and/or changing the pen width while drawing? it probably is possible, yet how? Any hints? .Floris

regular online meet-up
by Henning Hraban Ramm 12 Feb '25

12 Feb '25

You’re invited to our regular online meet-up, this upcoming Wednesday, February 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, 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...

Example, the formular is too much in the middle, should be mor left

Dear List, I have an example, where the formula should be more left. Maybe something with \startalign? setuppapersize[A4] \setcounter[userpage][439] \setupbodyfont[modern, 12.95pt] \setuplayout[backspace=2.9cm, width=13.50cm] \defineenumeration [theorem] [ text=Theorem, title=yes, width=fit, distance=0.2em, alternative=serried, ] \definetextbackground[GrayBackground][ location=paragraph, background=color, backgroundcolor=lightgray, leftoffset=.5\bodyfontsize, rightoffset=.5\bodyfontsize, topoffset=.5\bodyfontsize, bottomoffset=.5\bodyfontsize, frame=off,] \starttext \blackrule[color=black, height=0.10ex, width=13.50cm]\dontleavehmode \inrightmargin{\blackrule[color=black, height=0.10ex, width=1.11cm]\par {\bf 7.3.53}} \usecolors[svg] \setupinteraction [state=start, contrastcolor=cornflowerblue] \reference[Abschnitt:1]{7.3.52} {\bi Beweis (von Proposition \goto{7.3.53} [Abschnitt:1]). \tf Die Eigenschaften (i)-(iii) fol-\par gen unmittelbar durch leichte Rechnung aus der Definition. \blank (iv) \space \space Wir berechnen \m u × (\m v × \m w):\nospace \startformula \m u ×(\m v × \m w )=\m u × \startmathmatrix[fences=parenthesis] \NC \m v_2w_3 \NC - \NC \m v_3w_2 \NR \NC \m v_3w_1 \NC - \NC \m v_3w_2\NR \stopmathmatrix \stopformula Many thanks Uschi
