\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

> 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

Horizontal adjustment of left/right floats
by Aditya Mahajan 12 May '17

Hi, Is it possible to adjust the horizontal placement of left/right floats (similar to how 2*line etc can adjust the vertical placement). Minmal example: \starttext \startplacefigure[location={left,none}] \externalfigure[cow] \stopplacefigure \input knuth \stoptext Aditya

\xmlloadfile undefined
by dr. Hans van der Meer 12 May '17

12 May '17

In the xml-mkiv.pdf manual is written on page 18: > \xmlloadfile {...} {...} {...} > > loads the file FILE and registers it under NAME and applies either given or standard XMLSETUP (alias: \xmlload) > However, \xmlloadfile gives an undefined macro TeX-error, allthough the given alias \xmlload is present (useed beta of 2017-04-16). Shouldn't macro \xmlloadfile be added? Besides \xmlloadbuffer and \xmloaddata that would appeal to my preference for systematic naming. By the way. In this document all descriptions "\macro{}{}{}" refer to arguments like FILE, NAME etc. but these are absent from the API as shown. I think presented as \xmlloadfile{NAME}{FILE}{XMLSETUP} for example, would be more informative (at least I guess I have the order right). Any way, I get confused with some of the other APIs and would be pleased if a newer version of the manual has them. Hans van der Meer
