A tiny MWE: \starttext \startMPcode draw textext("\m{\max_i x_i}"); \stopMPcode \stoptext Could trace it down to '\math_function_handle_label' [math-ini] but not sure what MP is doing. Also looked into mp-mlib, mlib-pps but could not figure it out. I request you to kindly look into it.

[NTG-context] $\sin \theta$ behave differently in metafun
Dear all, I use $\sin \theta$ and $\cos \theta$ behave differently in text and in metafun. It works well sometime before but it doesn’t in metafun now. What is wrong in my example? Thank you for reading. Best regards, Dalyoung Here is a MWE. \startbuffer[pointCircle] numeric u; u:=1cm; pair A,B,C; draw fullcircle scaled 4u; A := dir(25)*2u; label.top(textext("$P=(\cos\theta, \sin\theta)$"), A); B := dir(-25)*2u; label.bot(textext("$Q=(\cos(-\theta), \sin(-\theta))$"), B); C := (xpart A, 0); label.lrt(textext("$A$"), C); label(textext("$O$"), origin); \stopbuffer \starttext I'd like use $\sin$ and $\cos$ in the metafun. But it shows strange text instead of $\sin$ and $\cos$. \processMPbuffer[pointCircle] \stoptext > 2022. 4. 13. 오전 11:09, ntg-context-requ...@ntg.nl 작성: > > Send ntg-context mailing list submissions to > ntg-context@ntg.nl > > To subscribe or unsubscribe via the World Wide Web, visit > https://mailman.ntg.nl/mailman/listinfo/ntg-context > or, via email, send a message with subject or body 'help' to > ntg-context-requ...@ntg.nl > > You can reach the person managing the list at > ntg-context-ow...@ntg.nl > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of ntg-context digest..." > > > Today's Topics: > > 1.

[NTG-context] placing (on) layers
Hi again, I’m always struggling with putting stuff on layers, since these just never start where I’d expect them to, and the offsets changed a few times within the last years. Please explain how I should define a layer that covers the whole page, since the following MWE is wrong (the layer always starts below the first line): \useMPlibrary[dum] \setuppapersize[A5][A4] \setuplayout[ marking=on, location=middle, ] \definemeasure[Bleed][3mm] \definemeasure[MaxHeight][{\dimexpr\paperheight + 2\measure{Bleed}\relax}] \definemeasure[MaxWidth][{\dimexpr\paperwidth + 2\measure{Bleed}\relax}] \definelayer[papier][ preset=lefttop, %x=0mm,y=0mm, width=\paperwidth, height=\paperheight, ] \setupbackgrounds[paper][background=cover,state=start] \starttext \showframe TEST \setlayerframed[papier][ preset=lefttop, %x=-\measure{Bleed}, %y=-\measure{Bleed}, offset=overlay, %frame=off, width=\measure{MaxWidth}, height=\measure{MaxHeight}, ]{\externalfigure[dummy][ width=\measure{MaxWidth},height=\measure{MaxHeight} ]} \flushlayer[papier] \stoptext ___ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://context.aanhet.net archive : https://bitbucket.org/phg/context-mirror/commits/ wiki : http://contextgarden.net ___
[NTG-context] cropoffset reduces paper size
Hi, at least in the current and previous LMTX beta, the paper size gets reduced if I use cropoffset as well as \setupinteractionscreen. (It is known that the PDF box settings only work with the latter.) In the MWE below, paper size gets reduced by cropoffset: \setuppapersize[A4] \setuplayout[ cropoffset=10mm, ] \setupinteractionscreen[ width=max,height=max, ] \starttext \showframe \samplefile{knuth} \stoptext If I set: \setuppapersize[A4][A4,oversized] \setuplayout[ marking=on, location=middle, cropoffset=7.5mm, ] Then the resulting paper size is A4, because the "oversized" factor is nulled by the crop offset. While I can work around this "feature", the behaviour is different from earlier versions. Can’t check with MkIV, since that doesn’t work any more, as reported by Pablo et al.

[NTG-context] new upload
Hi, I uploaded a new lmtx. Apart from a experimental intersection feature in the mp library (and metafun, more will be revealed when MS an I are okay with it) there is not that much news. I decided to turn some test code into a mechanism which is illustrated below. Adaptive boxes are hboxes that act a bit like glue which means that when we hook in e.g. a graphic it can be made to adapt. We can add some more methods if needed so maybe you see other usage. The interface is rather lightweight and the overhead is quite resonable.

Re: [NTG-context] right item marks for associative questions?

One more question: I am typesetting those questions in lua, because lua vectors were more convenient for reading the whole but I am not sure how should I pass the righttoleft option.
