Problem with Google Font 'Vollkorn'
by Michael Urban 12 Nov '21

12 Nov '21

I downloaded the Google free font ‘Vollkorn’ (https://fonts.google.com/specimen/Vollkorn) into an appropriate directory and ran mtxrun --script font --reload all went well, and the Vollkorn truetype fonts show up in the output of mtxrun --script font --list --all . However, the following input: \starttext \definedfont[name:vollkornregular*default at 14pt] \input tufte \stoptext fails, with the following output: system > ConTeXt ver: 2020.03.10 14:44 MKIV beta fmt: 2020.6.8 int: english/english fonts > otf loading > loading 'MYPATH/texmf/fonts/truetype/google/Vollkorn-Regular.ttf', hash 'vollkorn-regular' fonts > otf loading > loading failed due to read error fonts > defining > forced type 'ttf' of 'Vollkorn-Regular' not found fonts > defining > font with asked name 'Vollkorn-Regular' is not found using lookup 'name' fonts > defining > unknown font 'Vollkorn-Regular', loading aborted This is on Mac OSX. I don't recall this problem coming up before. Evidently the difficulty is that it is expecting an otf font and is confounded by the truetype file. The ConTeXt font system always bewilders me, but this time it's pretty specific. Help?

rule beneath chapter number
by jbf 12 Nov '21

12 Nov '21

The following MWE deliberately shows two ways of getting a short rule beneath a chapter number, but neither achieve what I want. \underbar is too close to the number and \crlf\blackrule too far below. So basically my question is: is there a way of adjusting the position of a brief rule beneath the number? It probably involves neither of the approaches I have used here, but I am not sure just what approach to take, other than using a background layer... and maybe that is what I need to do. Julian \define[2]\MyChapterCommand% {\framed[frame=on,bottomframe=off,leftframe=off,rightframe=off,topframe=off,align=middle] {\vbox{\headtext{chapter} \underbar{#1}\crlf\blackrule[height=.1\exheight]\crlf#2}}} \setuphead[chapter][ header=empty, alternative=middle, style={\ssb}, number=yes, command=\MyChapterCommand, after={\blank[big]}, ] \setuplabeltext[chapter= ] \starttext \chapter[title={Chapter title}] \stoptext

spreadsheet product of two cells in current row
by juh 12 Nov '21

12 Nov '21

Dear all, I thought I could find my way through the spreadsheet documentation to make my invoices. While it is simple to calculate the sum or the product of two cells if you know that they are A[2] and B[2] I can't find the solution to access cell A and B *on the same row*. Amount | Single | Sum 2 | 5 | 10 <-- A[currentrow] * B[currentrow] does not work 3 | 4 | 12 ==================== Sum 22 The rows come from a script and there might be several items. Any hints? juh -- Autoren-Homepage: ......... http://literatur.hasecke.com Satiren & Essays: ......... http://www.sudelbuch.de Privater Blog: ............ http://www.hasecke.eu Netzliteratur-Projekt: .... http://www.generationenprojekt.de

Synonyms feature request
by Rik Kabel 12 Nov '21

12 Nov '21

Hello developers, Is it possible to get a mechanism to reset and setup synonyms by way (page, part, chapter, section, ...)? This is not a high-priority request. I currently accomplish this in the after key of chapter setuphead definitions. However, it seems cleaner to define it when the synonym list is defined instead of adding a resetshownsynonyms and setsynonyms to the chapter definition for every new synonym list. -- Rik

Achieving the effect of \overset outside math mode
by kauśika 11 Nov '21

11 Nov '21

Dear list, I don't have a MWE per se, but as the title suggests, I want to be able to achieve the effect of \overset outside math mode. As I understand, \overset itself is implemented using \mathop and \limits. Currently to achieve this I have defined some macros using \offset thus : \define[1]\pabv{\dontleavehmode\offset[width=0em,y=-16pt,x=3pt]{#1}} Unfortunately, I have to hard code the x values. So I have define several such macros with different offsets. Not an elegant solution, but it is what I could muster. So, my objective is to place a smaller piece of text above another larger piece of text so that the text above is centered w.r.t the text below. Please advise. Thanks, kauśika

Math font tips and tricks
by Alexandre Christe 11 Nov '21

11 Nov '21

Dear all, I'd like to know how best to work with font features regarding adaptations of math fonts. For example, let's assume I'd like to use Minion Pro also for math typesetting. I've referred myself to this page of the Wiki https://wiki.contextgarden.net/Command/definefontfallback. I have tried the following, but it fails for greek letters in math mode. \definefallbackfamily [mainface] [math] [Minion Pro] [range={math:lowercaseitalic,math:uppercaseitalic,math:lowercasenormal,math:uppercasenormal},force=yes] \definefallbackfamily [mainface] [math] [Minion Pro] [range={math:lowercasegreekitalic,math:uppercasegreekitalic,math:lowercasegreeknormal,math:uppercasegreeknormal},force=yes] \definefallbackfamily [mainface] [math] [Minion Pro] [range=math:digitsnormal,features=f:lining,force=yes] \definefontfamily [mainface] [math] [Libertinus Math] Thanks in advance for your support.

repeat layer recto pages
by jbf 10 Nov '21

10 Nov '21

I want a particular layer to repeat on recto pages only, but I don't want this to happen in frontmatter, only in bodymatter. This is what I have done, just before the first chapter after \startbodymatter (but unsuccessfully; the layer repeats for every page at the moment. I must have omitted something). \startbodymatter \setupbackgrounds [rightpage] [background=butterfly] \startchapter[title={Chapter title}] \definelayer[butterfly] [x=0mm, y=0mm,repeat=yes,width=\paperwidth, height=\paperheight] \setlayer[butterfly] [hoffset=.99\textwidth, voffset=1cm] {\externalfigure[bfly.jpg][width=1.5cm]} \setupbackgrounds[page][background=butterfly] etc. Any thoughts?

Concerning \installparameterhashhandler and family
by Jairo A. del Rio 10 Nov '21

10 Nov '21

Hi. Reading at mult-aux.mkxl, I've seen command handlers define, among others, \installparameterhashhandler, However, in files such as those related with symbol management, only \installparameterhandler and \installsetuphandler are. When writing basic modules, sometimes only the "raw" macros above are actually needed. So, what are "parameterset", "hashhander", "rootparameterhandler", etc. for? Where would they ease module writing? Thank you a lot and sorry for the long question. Best regards, Jairo
