Dear ConTeXt users, Last time, this is what I wanted, and Hans provided me an example: https://www.mail-archive.com/ntg-context@ntg.nl/msg78079.html However, the example given in that e-mail does not work with my Debian context 2016.05.17.20160523-1. Could you please help me out again? I get: /usr/share/texmf/tex/context/base/mkiv/core-uti.lua:165: attempt to index upvalue 'tobesavedmacros' (a nil value) Thanks. Kumar -- Kumar Appaiah

\Umathquad\displaystyle not set
by Kumar Appaiah 09 Feb '17

09 Feb '17

Dear ConTeXt users, I have a custom slide template that I borrowed from another source years ago. It works well on my Debian machine, but when I try to build the PDF on a docker vm on Gitlab, I run into the \Umathquad\displaystyle not set error. Surprisingly, that error doesn't crop up on my machine. Here is the complete (working) repository: https://gitlab.com/kumanna/context-slides/tree/master Here is the commit that causes the error online. Notice that I am adding the {\bf \nabla} character: https://gitlab.com/kumanna/context-slides/commit/b723c15dff6d7312605947f8bf… Here is the failed build log: https://gitlab.com/kumanna/context-slides/builds/9972477 Is there something I am missing? Thanks. Kumar

Bibliography sorting order by Czech alphabet in Context
by Petra Janouchová 08 Feb '17

08 Feb '17

Hello, I am fairly new to the ConTeXt community and I am trying to sort bibliographical references for my thesis. I need to be able to set the sorting order of the bibliographical references by Czech alphabet (e.g., C,Č,D,....Ch,...etc.). English sorting puts Ch before C or Č, but in Czech it needs to be after D. Any ideas? http://tex.stackexchange.com/questions/352496/bibliography-sorting-order-by… Here is the minimal example \mainlanguage[cz] \usebtxdataset[bibliotest.bib] \usebtxdefinitions[apa] \unprotect %here I substitute the annoying ampersand with czech a \def\textampersand{a} \protect \setupbtx [apa:cite] [left=, right=, separator:2={\btxsemicolon}, % :0 and :1 - between items of a list separator:3={\btxsemicolon}, separator:4={\btxsemicolon}, separator:names:2={\btxcomma}, separator:names:3={\btxcomma}, separator:names:4={\btxcomma}, etaldisplay=3, etallimit=3 ] \starttext \cite[righttext={{123},{116-156}}][Danton2004, Cicikova2011]. \cite[Cicikova2011] \cite[Chichikova1978] \startchapter[title=Bibliografie] \placelistofpublications \stopchapter \stoptext and the database bibliotest.bib @book{Danton2004, address = {Oxford}, author = {Danton, Gocha R. and {De Angelis}, Franco}, publisher = {Oxford University School of Archaeology}, title = {{The archaeology of Greek colonisation: essays dedicated to Sir John Boardman}}, year = {2004} } @article{Cicikova2011, address = {Kazanlak}, annote = {PDF}, author = {{\v{C}}i{\v{c}}ikova, M}, pages = {116--121}, journal = {{Varia Thracica}}, title = {{Article Title}}, year = {2011} } @book{Chichikova1978, address = {Oxford}, author = {Chichikova, Maria and Dimitrov, Dimitur P. and Alexieva, Marguerite and Author, Name}, isbn = {0-86054-003-0}, keywords = {Seuthopolis,Thracians}, language = {eng}, publisher = {BAR Supplementary Series 38}, title = {{The Thracian city of Seuthopolis}}, year = {1978} } Thanks in advance, Petra -- *Petra Janouchová* Doctoral candidate of Ancient history, Faculty of Arts, Charles University in Prague https://cuni.academia.edu/PetraJanouchova petra.janouchova(a)gmail.com

Overriding a font face in a typescript
by Rik Kabel 07 Feb '17

07 Feb '17

ConTeXters, How can I override one or two faces in a typescript? I prefer to use the semibold face in my document wherever an emboldened face is used. I would prefer to refer to it as \bf, or style=bold. (Similarly for semibolditalic.) I currently reproduce the existing typescript in my document, substituting the semibold variants for the bold. Is it possible to use the standard typescript by reference (\usetypescript) and then override those two faces? -- Rik

Encoding reserved characters in URI query strings
by Rogers, Michael K 07 Feb '17

07 Feb '17

Let's say I want a link to plot x+2 in Wolfram|Alpha. I need to catenate "http://www.wolframalpha.com/input/?i=" and "plot+x%2B2". Is there any way already available in ConTeXt to translate reserved characters like "+" to the percent-hexcode "%2B"? Something like \encode[plot x+2] would become plot+x%2B2 Or more generally, some languages have a query constructor like this \queryURI [http://www.wolframalpha.com/input] [i=plot x+2] which would construct the URI http://www.wolframalpha.com/input/?i=plot+x%2B2 I could write my own, of course. But no need to reinvent the wheel.

issue with xtables

Dear list, I have the following sample: \setupindenting[yes, always, big] \setupfloatcaption[table][location=none] \setupfloat[table][indentnext=no, spacebefore=5em] \starttext \input zapf \placetable{}{ \startembeddedxtable \startxrow \startxcell knuth \stopxcell \startxcell \input knuth \stopxcell \stopxrow \stopembeddedxtable } \input zapf \stoptext I would like to configure a different spacing before and after the embeddedxtable, but all options for \setupfloat in strc-flt.mkiv and related to spacing don’t seem to work. What am I missing in float spacing? Many thanks for your help, Pablo -- http://www.ousia.tk

How to use \setupitemgroup?
by Csikos Bela 04 Feb '17

04 Feb '17

Dear context users: I have troubles using \setupitemgroup. I tried to use it based on the contextgarden wiki page (http://wiki.contextgarden.net/Command/setupitemgroup) description, but either my understanding how to use it is not correct or the command doesn't behave as described on the wiki page. In the following example I want the items to be in a numbered, packed list, where the item numbers are followed by ), like 1) 2) etc. If I don't add stopper=) option, I get a numbered list, but it's not packed. If I add stopper=), the list becomes an unnumbered list, but packed. I use context standalone ConTeXt ver: 2016.09.24 12:40 MKIV beta. I attach the resulted pdfs. What do I do wrong? Thanks, bcsikos example code: \definefontfamily[docu][rm][Tex Gyre Heros] % I want to use ss fonts only \setupbodyfont[docu,12pt] \setuppagenumbering[state=stop] \setupitemgroup[itemize][each][packed,joinedup][n] % or use this: %\setupitemgroup[itemize][each][packed,joinedup][n,stopper=)] \starttext \startalignment[middle] {\tfa PINK FLOYD} {\tfa The Wall} \stopalignment \blank {\bf Compact Disc 1} \startitemize \item In The Flesh? 3:19 \item The Thin Ice 2:29 \item Another Brick In The Wall (Part 1) 3:09 \item The Happiest Days Of Our Lives 1:50 \item Another Brick In The Wall (Part 2) 3:59 \item Mother 5:33 \item Goodbye Blue Sky 2:47 \item Empty Spaces 2:08 \item Young Lust 3:31 \item One Of My Turns 3:36 \item Don't Leave Me Now 4:16 \item Another Brick In The Wall (Part 3) 1:14 \item Goodbye Cruel World 1:15 \stopitemize \blank {\bf Compact Disc 2} \startitemize \item Hey You 4:41 \item Is There Anybody Out There? 2:40 \item Nobody Home 3:24 \item Vera 1:33 \item Bring The Boys Back Home 1:27 \item Comfortably Numb 6:21 \item The Show Must Go On 1:36 \item In The Flesh 4:16 \item Run Like Hell 4:23 \item Waiting For The Worms 3:58 \item Stop 0:30 \item The Trial 5:19 \item Outside The Wall 1:43 \stopitemize \stoptext

URL styling in btx bibliography
by Rik Kabel 04 Feb '17

04 Feb '17

ConTeXters, Is there a user-level control for the styling of urls in the new bibliography system? I use \setupurl[style=\addff{f:ns}\ss] (where f:ns is a fontfeature definition for lining/new style numerals) for the rest of the document. The bibliography honors this formatting for urls present in bibtex note entries, but persists in serif and oldstyle (the document defaults) for urls provided by bibtex url entries. -- Rik

[Far out subproject proposal] ---Have ConTeXt generate html math inaddition to pdf/dvi ?
by Federer Fanatic 02 Feb '17

02 Feb '17

Hi, I was wondering if: -------------------------------- Basically have complete mathml markup or some other kind of html math output that is completely capable of doing what is now done for pdf output. This would elminate the need for the clumsy workarounds that mathjax, for example, provides---there appears to be no easy way to convert arbitarilly/personally written latex packages/classes into something that mathjax can understand. Obviously the original latex code could still remain in the resulting html/mathhtml output so that people would still have access to the "original" source code. One of my motivations is to allow for google translate to work on html math documents... it WORKS provided you add 'notranslate' to the spans: <span class="math inline">, <class="math display">latex math commands/span> etc environments. However LaTeX commands that mathjax is not familiar with are not rendered.... I realize this may be a better question on mathjax but I regard that project, while laudable, wrong headed as the real problem should be solved by a proper TeX-like engine like ConTeXt can solve this problem(s)? -------------------------------------------------------------- Roger Federer Fanatic Extraordinaire :-)
