[OT] Mini-keypad for typing math symbols
by Bruce Horrocks 21 Jul '25

21 Jul '25

<https://www.crowdsupply.com/summa-cogni/mathpad> This might be of interest to some. I have no affiliation with the developer. It's a specialised keypad that sits alongside your normal keyboard and provides rapid access to 112 mathematical symbols and Greek letters, saving the need to hunt around in fiddly character viewers. It's switchable between Word, OpenOffice and LaTeX — Bruce Horrocks Hampshire, UK

linebreak in setupheadertexts
by Thomas Meyer 21 Jul '25

21 Jul '25

Hi folks, once again I have a problem that I can't solve: I would like to have a linebreak for \setupheadertexts. \setupheadertexts [{\bf Johnson}, Uwe][{\sl Mutmassungen über Jakob}] \starttext Freiheit ist die Einsicht in die Notwendigkeit. \stoptext *Johnson,* Uwe should be the result. Unfortunately, what I have tried (\\, \crlf, \break) does not work. Thanks for any help Tómas

upload
by Hans Hagen 21 Jul '25

21 Jul '25

Hi, I uploaded lmtx, with a few fixes (like size in math fences) and additions (like a language key in highlights). However, the most intrusive change is that we also do some overload protection (currently configured as warning) on values, so for instance some (primitive) token lists and parameters are now protected against overloads. So, we already had protection at the \cs level, now we also have at the value level (\count<n> etc). Think: \permanent\def\foo{...} % \foo can't be redefined \newcount\mycounter % \mycounter is defined permanent by default \immutable\mycounter 123 % \mycounter can't be changed (@ user level) and alike. This second feature is mostly for deep-down definitions and usage. In the future some more quantities might get that level of protection. Just for the record, this is also supposed to be active at the lua level. In a similar fashion we have (already) some protection for callback abuse in place. The additional overhead can be neglected. It can be that we have some unforeseen side effects but the test suite runs ok as do some of mikaels more complex and demanding documents (that we use to test this).

Problem with the second \HL in the matrix
by Ursula Hermann 21 Jul '25

21 Jul '25

Dear List, After some work I have this example. \starttext \startformula \startmathmatrix [fences=parenthesis] \VL\NR \HL \NC \NC \NC \NC \NC \NC \VL \NR \stopmathmatrix \stopformula \stoptext My problem is, that after the second \VL the \HL goes on the left side, and is too long, and not on the right side. Should be as the first one, but shorter. Many thanks Uschi

Animation using MetaFun
by Jeong Dal 20 Jul '25

20 Jul '25

Dear all, I tried to make an animation which draws Cardioid curve. I found a code which draws Cardioid using circles. Since I’d like to draw it differently, I modified it a little. 1. Define the z[] values in the \startMPdefinitions block 2. Modified the drawing method in \startMPbuffer When I run it, it doesn’t recognize the z[] values defined already. I think that the z[] values are not delivered to \startbuffer. I tried \startMPinclusions, \startMPinitialization, but I couldn’t succeed. 1. How can I deliver the z[] values into the buffer? 2. What is wrong in the following code? Thank you for reading. Best regards, Dalyoung \usemodule[animation] \setupinteraction[state=start] \startMPdefinitions%{Cardioid} path p,q; numeric u, ang,j,num; picture pict; u := 1cm; ang := 360/52; p := fullcircle scaled 5u; for i=0 upto 51: z[i] = 2.5*dir(ang*i)*u; endfor; pict := image ( draw p withpen pencircle scaled 1; ); \stopMPdefinitions \startbuffer[Cardioid][s] draw pict; num := \MPrawvar{Cardioid}{s}; for i = 0 upto num: j := 2i mod 52; draw z[i] -- z[j]; endfor; setbounds currentpicture to boundingbox currentpicture enlarged 2mm ; \stopbuffer \startdocument \startanimation[menu=yes, framerate=7] \dorecurse{52} {\startexpanded \startframe \setupMPvariables[Cardioid][s=\recurselevel] \processMPbuffer[Cardioid] \stopframe \stopexpanded} \stopanimation \stopdocument

language in tagging and export
by Hans Hagen 18 Jul '25

18 Jul '25

Hi, A while ago there was some demand for language support in tagging and export (which already has some). One approach is to do it automatically, so test {\nl test} test would then be split in pieces but also error prone and maybe non-intentional. But then one can actually wonder about structure there anywaym so this makes more sense: \definehighlight[isdutch] [language=nl,color=darkred] \definehighlight[isgerman] [language=de,color=darkblue] \definestartstop[someczech] [language=cz,color=darkgreen] \definestartstop[somefrench][language=fr,color=darkyellow] % pablo will check the other languages and also the % kind of language tags we want to end up in the pdf % as he will check how viewers 'speak' - yesterday i % suddenly got some english youtube video where the % normally low pitch male voice (that i knew) became % high pitch female dutch for no reason ... and i % never asked for that ... so I fear future pdf % viewers test \isdutch {test} test test \isgerman {test} test test \someczech {test} test test \somefrench{test} test so that is what i added. Now, the question is, what commands (environments) need support for the language key; we have some 70 potential places and 270 possible edits .. oneliners, but kind of boring as we need to expliclty check where it kicks in (probably needs some distracting music on the speaker to get it done) Concerning impact on performance, I tested with 10000 * 2 of the above highlights and got this: % 20K no support : 2.52 % 20K language not set : 2.55 % 20K language set : 3.12 % needs to be compensated so we loose some performance which means i have to gain in back someplace else (kind of regular challenge when adding something) so, the question is 'selective' or 'everywhere' (this is independent of tagging etc ... assuming some structure it's trivial to add there; a general {\nl test} is more tricky as then we need to do more consistency testing, which i got kind of working and then removed again because in the end we then reward sloppy code which is bad and we should stay away from that) Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | www.pragma-ade.nl | www.pragma-pod.nl -----------------------------------------------------------------

weird issue with latest win64 binaries
by Pablo Rodriguez 18 Jul '25

18 Jul '25

Dear list, I‘m afraid that after updating to current latest (2025.07.08 17:48) at work in Win10, the win64 binaries didn’t work at all. Both `context --version` and `luametatex --version` gave the following message (and no more than that): Access denied Since I make a backup before updating, using the previous version is totally fine. Is there anything changed in the compilation that could affect binary execution? Many thanks for your help, Pablo

Frame/hrules around column content
by Florent Michel 16 Jul '25

16 Jul '25

Hi, I have encountered another issue with columns: it seems that in some cases the height of the content is not entirely accounted for. From the small experiments I made, the problem seems to only occur when the content of the left column is larger than the content of the right one by a fraction of the line height. The example below demonstrates the issue. The same issue seems to occur with \startboxedcolumns ... \stopboxedcolumns but not with \startsimplecolumns ... \stopsimplecolumns. Is there a way to have a frame or hrules around the full content of \startcolumns ... \stopcolumns? _______________________________________________________________________ \starttext % The left frame is slightly too small \startcolumns[n=2,frame=on] Line \par \blank[1.5ex] Line \par Line \par Line \stopcolumns \blank[big] % Same issue with hrules: the lower one overlaps with the content of the left column \hrule \startcolumns[n=2] Line \par \blank[1.5ex] Line \par Line \par Line \stopcolumns \hrule \blank[big] % Same issue with \startframed ... \stopframed \startframed[offset=none] \startcolumns[n=2] Line \par \blank[1.5ex] Line \par Line \par Line \stopcolumns \stopframed \blank[big] % Using strut=local seems to fix the issue in this case... \startframed[offset=none,strut=local] \startcolumns[n=2] Line \par \blank[1.5ex] Line \par Line \par Line \stopcolumns \stopframed \blank[big] % ... but becomes a problem on this example... \startframed[offset=none,strut=local] \startcolumns[n=2] A longer phrase which does not fit on one single line \par Line \par \stopcolumns \stopframed \blank[big] % ... which works fine without strut=local \startframed[offset=none] \startcolumns[n=2] A longer phrase which does not fit on one single line \par Line \par \stopcolumns \stopframed \blank[big] % Using \startsimplecolumns ... \stopsimplecolumns seems to consistently give a good enough frame % (although with maybe a bit too much white space at the bottom in this case) \startframed[offset=none] \startsimplecolumns[n=2] Line \par \blank[1.5ex] Line \par Line \par Line \stopsimplecolumns \stopframed \stoptext _______________________________________________________________________ Cheers, Florent

Vertical alignment and columns
by Florent Michel 15 Jul '25

15 Jul '25

Hi! I've encountered a (to me) unexpected behaviour with the columns environment: the vertical alignment looks slightly different depending on whether the text fits on a single column or not. The following example demonstrates this behaviour (ConTeXt LMTX version 2025.07.08 17:48 on a 64-bits Linux machine): the first line looks slightly higher than the second one. \starttext \startframed[offset=0pt] \startcolumns This is a test \stopcolumns \stopframed \blank[medium] \startframed[offset=0pt] \startcolumns This is a slightly longer test using two columns \stopcolumns \stopframed \stoptext If this is intended, is there a way to get the same vertical alignment independently of whether the text fits on one or two columns? Cheers, Florent
