Invalid href in ToC in exported html
by Florent Michel 16 Feb '25

16 Feb '25

Hi, It seems (unless I am missing something) that hyperlinks in the table of contents for the exported html are incorrect when `reference` is set. Minimal(-ish) working example: _________________________________ \setupbackend[export=yes] \setupinteraction[state=start] \starttext \placecontent \startchapter[title=Chapter 1] Blahblah \stopchapter \startchapter[title=Chapter 2, reference=chapter_2] Blahblahblah \stopchapter \stoptext _________________________________ Annotated relevant part of the generated `.html`: ... <div> <div class="list"> <div class="listitem chapter" href="#aut-1" onclick="location.href='#aut-1'">  <div class="listtag">1</div> <div class="listcontent">Chapter 1</div> <div class="listpage">2</div> </div> <div class="listitem chapter" href="#aut-2" onclick="location.href='#aut-2'">  <div class="listtag">2</div> <div class="listcontent">Chapter 2</div> <div class="listpage">3</div> </div> </div> <div class="section chapter level-2" id="aut-1"> <div class="sectioncaption"> <div class="sectionnumber">1</div> <div class="sectiontitle">Chapter 1</div> </div> <div class="sectioncontent"> Blahblah </div> </div> <div class="section chapter level-2" id="chapter_2"> <div class="sectioncaption"> <div class="sectionnumber">2</div> <div class="sectiontitle">Chapter 2</div> </div> <div class="sectioncontent"> Blahblahblah </div> </div> </div> ... Would someone be aware of a workaround (apart from using ‘aut-2’ as reference in this case) or other solution? Best regards, Florent

extending protrusion values for Greek characters
by Pablo Rodriguez 16 Feb '25

16 Feb '25

Dear list, as I’m playing with column sets for parallel texts, I have noticed that some Greek characters lack protrusion values. Is there a way to add them (as an extension to "protrusion=quality" values) to a single document? This would be great to test them (to consider their addition to main ConTeXt in the future). Many thanks for your help, Pablo

cutting pages for booklet
by Pablo Rodriguez 15 Feb '25

15 Feb '25

Dear list, the way to have a booklet is straightforward: \setuppapersize[A4][A3, landscape] \setuparranging[2UP] \setupbodyfont[128pt] \setupmakeup[page] [pagestate=start, align=center, style=\ssbfd] \starttext \dorecurse{24} {\startmakeup[page]\recurselevel\stopmakeup} \stoptext But what happens if I already have landscape A3 that I need to print as an A4 booklet? I mean, which is the way to instruct ConTeXt to cut each A3 page in half and arrange each half in its proper position in the booklet? Many thanks for your help, Pablo

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