overbraces in concrete mathematics - bug?

Hi, With the below, the overbraces appear too high (the underbraces are in the right position) \starttext \switchtobodyfont[concrete] \startformula \overbrace{a+a} \underbrace{a+a} \stopformula \stoptext Would appreciate if somebody can tell me if they see the same, or if this is a bug. The version of ConTeXt I use is below. Thanks!

Problem with Metapost

Hi, I think I have never encountered this problem. Recently, I can no longer have a succession of figures with Metapost; only the first one appears. Thanks. Fabrice \starttext \dorecurse{3}{\startMPcode numeric u; u = 0.5cm; ymax = xmax = 7; xmin = ymin = -1; interim ahangle := 30; z0 = (1u,1u); z1 = (2u,3u); z2 = (0,5u); path xx, yy; xx = ((xmin,0) -- (xmax,0)) scaled u; yy = ((0,ymin) -- (0,ymax)) scaled u; drawoptions(scaled .5 withcolor .7 white); for i = ceiling ymin upto floor ymax: draw xx shifted (0,i*u); endfor for i = ceiling xmin upto floor xmax: draw yy shifted (i*u,0); endfor drawoptions(); path fuzz; fuzz = z0 -- z1 -- z2 -- cycle; fill fuzz withcolor 0.7[blue,white]; draw fuzz withcolor blue; fill fuzz shifted(4u,1u) withcolor 0.7[blue,white]; draw fuzz shifted(4u,1u) withcolor blue; drawoptions(withpen pencircle scaled 1pt); drawarrow z0 -- z0 shifted (4u,1u); drawarrow z1 -- z1 shifted (4u,1u); drawarrow z2 -- z2 shifted (4u,1u); drawoptions(); label("\im{\vec{v}}", (3.5u,3u)); label.llft("\im{A}",z0); label.lrt("\im{B}",z0 shifted (4u,1u)); \stopMPcode} \stoptext

How to force section title to be on same page as some of the content?
by Joel 03 Nov '24

\define[9]\event{% \staged{#9} \startsubsection[title={\recurselevel.\getvalue{activitynumber}~~~#9}, reference={activity_\activitynumber_\recurselevel}]% \activitytype{#9}% #2% \doifsomething{#4}{% \FrameTitle{\strut \bf Suggested Materials}% \StartFrame% \startitemize[columns,two,2]% #4% student's materials% \stopitemize% \StopFrame% }% \doifsomething{#6}{% {\boldface #6}% student's directions% }% \doifsomething{#7}{% #7 % student's task% }% \doifsomething{#8}{% %\color[white]{...}% \FrameTitle{\strut \bf Requirements}% \StartFrame% \startitemize[9]% #8 % requirements% \stopitemize% \StopFrame% }% \stopsubsection%}% I have a macro above. Basically it quite simply is used to define a classroom activity for students to do. Each classroom activity contains: - A subsection title. - A list of recommended materials (like scissors, glue). - Instructions directed at the student. - Where student write their answers. - A list of requirements, how it will be graded. In testing, I found students are ALWAYS very confused by page breaks: If the assignment title, supplies, and instructions appear on one page, but the area they write/body is on the next page, split there by a page break, the students think the activity is missing. They cannot find the activity. So basically, I need to make it such that items 1, 2, and 3 must appear with at least the start of 4, even if its just the first problem in 10, and even if this means leaving a blank area on the page in front of it. How can I be so precise making sure the page break doesn't seperate the title from the start of the area where students write their answers? Adding page breaks before every activity isn't a good solution, it wastes paper. --Joel

Hi Hans, hi all, yesterday I tried to freshly install the recent lmtx version on 64 Linux arm. It crashes with the appended cont-en-error.log Is this only my (minor) problem? Greetings Lutz
