mathdigits no longer works
by Mohammad Hossein Bateni 15 May '17

15 May '17

Hi, The example for replacing Arabic numerals by Indic digits inside math used to work (at least) until version 2017.01.17 17:37. tex/texmf-context/tex/context/fonts/mkiv/type-imp-mathdigits.mkiv Now in version 2017.04.27 01:00, this does not produce the desired output: it's all "Latin" digits. Has something changed regarding fontfallback definitions? Thanks, MHB

\xmlload not understood
by dr. Hans van der Meer 15 May '17

I did load an xml data file containing <nodes><subnode>...</subnode></nodes> with: \xmlload{Data}{data.xml} Then correctly find the number of data from \xmlcount{Data}{subnode} however \xmlflush{Data} is not giving me the processed nodes from \startxmlsetups do:subnode doing something with xmlflysh{#1} \stopxmlsetups but only the raw input <nodes><subnode>...</subnode></nodes> Do I err in my understanding? And if so, how to do it better? Below a minimal example and its output. \startxmlsetups load:setups \xmlsetsetup{#1}{root|nodes|subnode}{load:*} \stopxmlsetups \xmlregistersetup{load:setups} \startxmlsetups load:root \xmlloadbuffer{Data}{dataset} Number of <subnodes> = \xmlcount{Data}{subnode}\blank \xmlflush{Data} \stopxmlsetups \startxmlsetups load:subnode Content <subnode> \xmlflush{#1}\par \stopxmlsetups \startbuffer[test] <?xml version="1.0" encoding="UTF-8"?> <root></root> \stopbuffer \startbuffer[dataset] <?xml version="1.0" encoding="UTF-8"?> <nodes> <subnode>this is subnode-1</subnode> <subnode>this is subnode-2</subnode> <subnode>this is subnode-3</subnode> </nodes> \stopbuffer \starttext \xmlprocessbuffer{root}{test}{} \hairline \stoptext

\definenamespace and the list option
by Henri Menke 15 May '17

15 May '17

Dear list, Motivated by this question on TeX.SX https://tex.stackexchange.com/questions/369778 I took a look at the \definenamespace mechanism in ConTeXt. It seems that it permits a syntax like \define<NAMESPACE>[...,...][...=...,...=...] where you can provide a list of instances to define in the first argument. I don't know about any \define command in ConTeXt that would permit that and the implementation in mult-aux.mkiv does not even support that properly. My approach would actually be to remove the list option from \definenamespace completely. Cheers, Henri

Location of primes and strange latin modern font
by Akira Kakuto 14 May '17

> Will the primes also get fixed? In the latest standalone (I downloaded > it minutes ago), I get the attached result running the same test file. It seems that the primes are not yet fixed in mtx-context | current version: 2017.05.14 19:09 It requires, for example: \starttext Compare ${u_p}\hskip-.5em''$ and $u''_{\hskip-.63em p}$ with $u''$ \stoptext Best, Akira

Bug with Enumeration and \dfrac{}{} with Standalone ?
by Fabrice Couvreur 14 May '17

14 May '17

Hello, I am posting again on the same subject but with more precision. I use Standalone Context in its latest version. We can observe that the alignment is not correct with \dfrac{}{} but it is with {}\ over{}. But if I use Texlive 2016 there are no problems. Thank you Fabrice ######################################################### \starttext \startitemize[n][stopper={.},style=bold,color=darkred] \item Soit \math{f} la fonction définie pour tout réel \m{x} différent de \m{-1} par \math{f(x)=\dfrac{x+2}{x+1}} et \math{\cal C} sa courbe représentative dans un repère du plan. \startitemize[a][stopper={.},style=bold,color=darkred] \item L'image de 3 par la fonction \math{f} est : \startitemize[i,columns,joinedup,three] [stopper={.},style=bold,color=darkred,grid=line] \item \math{{14}\over {3}} \item \math{{5}\over {4}} \item \math{2} \stopitemize \startitemize[i,columns,joinedup,three] [stopper={.},style=bold,color=darkred,grid=line] \item \math{\dfrac{14}{3}} \item \math{\dfrac{5}{4}} \item \math{2} \stopitemize \stopitemize \stopitemize #########################################################

definefallbackfamily and utfchar, something changed?
by Mikael P. Sundqvist 13 May '17

13 May '17

Hi, the Lucida font does not have all variants of \heartsuit, \varheartsuit and so on (see for example http://mirror.unl.edu/ctan/macros/latex/contrib/unicode-math/unimath-symbol… for their unicode slots). For this reason I borrow these symbols from Xits. The code below used to work, but not anymore (I updated to latest standalone today, not sure when it stopped work). I don't get Xits symbols at all, but only a filled diamondsuit from vardiamondsuit. That one belongs to the Lucida font. Any ideas on how to fix this issue? Best regards, Mikael PS: I'm sorry for using a commercial font in an example. If requested, I gladly change that. %% Test file \definefallbackfamily [lucidaopentype][mm][Xits Math][range={2660,2661,2662,2663,2664,2665,2666,2667}] \definefontfamily[lucidaopentype][rm][Lucida Bright OT] \definefontfamily[lucidaopentype][ss][Lucida Sans OT] \definefontfamily[lucidaopentype][tt][Lucida Sans Typewriter OT] \definefontfamily[lucidaopentype][mm][Lucida Bright Math OT] \setupbodyfont[lucidaopentype] \def\diamondsuit{\utfchar{"02662}} \def\varspadesuit{\utfchar{"02664}} \def\varheartsuit{\utfchar{"02665}} \def\vardiamondsuit{\utfchar{"02666}} \def\varclubsuit{\utfchar{"02667}} \starttext Test: $\vardiamondsuit$ and $\diamondsuit$ \stoptext

Location of primes and strange latin modern font
by Mikael P. Sundqvist 13 May '17

13 May '17

Dear list, I posted this question on stack exchange (https://tex.stackexchange.com/q/369226/52406) and got the suggestion that it might be a bug, and therefore I post it here as well: I have a problem with typesetting derivatives (and latin modern) in ConTeXt in latest standalone. Minimal example: \starttext Compare $u_p''$ and $u''_p$ with $u''$ \stoptext Please see the attached image for the output (here I have also included the corresponding output, compiling a similar simple document in LaTeX, where things look as I expect.) Basically, I have two questions: 1) How should I write derivatives (say second derivatives) in ConTeXt? I think that the primes are too far away from each other. In particular when the subscript $p$ is there (the first formula). 2) The math font looks strange (or should I say different) in the ConTeXt example. (Wrong size, scaled?) For a while I thought that the second problem might be because I define no font. But the following example gives a similar result. \definefontfamily[myface][rm][Latin Modern Roman] \definefontfamily[myface][mm][Latin Modern Math] \setupbodyfont[myface] \starttext Compare $u_p''$ and $u''_p$ with $u''$ \stoptext Any ideas? /Mikael

Table of content in presentation example
by cryo shock 13 May '17

13 May '17

Hi guys, I downloaded a sample presentation with component and example presentation from a link off of ctxwiki. I will attach both files and a premade PDF that shows what I mean. So far I edited the component a little in display style, yet I don't know why I can't get a simple table of content on the second slide. In the component I found the following code: \definehead [slide] [subject] [ style=\ssbfc, color=foreground:contrast, alternative=middle, page=yes ] So I understand that the head called slide comes from the head subject, which by default isn't shown in the table of content. So I searched ctxwiki for table of content and modified the above setup to \definehead [slide] [subject] % default: subject [ style=\ssbfc, color=foreground:contrast, alternative=middle, page=yes, * incrementnumber=yes, % keep track of the number* * number=no % but don't show it* ] I also added the following line: \setuplist[subject][width=2cm] The example .tex then starts with \starttext \setvariables ... \startslide ... \stopslide ... \stoptext So I inserted another \startslide \stopslide with \placecontent in between: \startslide[title={T.o.c.}] \placecontent \stopslide Yet the rendered PDF shows only a blank page where the TOC is supposed to be. Can anybody tell me what I am doing wrong? Thanks in advance, Sebastian
