accessing xml element attributes in lua, how, if you do not want to use the .at scheme?
by Gerben Wierda 09 Jun '20

09 Jun '20

I’ve been trying to find out how I can access XML node properties/attributes in lua other than via the .at syntactic scheme but using the property/attribute name as a string. E.g., currently I do: someVar = someNode.at.someProperty but I would like to do something like someVar = someNode[“someProperty”] or someNode.attribute(“someProperty”) or something where I can use the string version of the properties/attribute name. It’s probably possible (after all these are all dynamic structures that come from data), but how exactly? Thanks, G

Bug in lmtx or wrong setup?
by Jan U. Hasecke 09 Jun '20

09 Jun '20

Hi all, I encountered a very strange problem. I want to have section headlines expanding the whole textarea, but the following copy text of the section shall be typeset in columns. I have this setup and it works fine. \setuphead [section] [ insidesection=\startcolumns, aftersection=\stopcolumns, ] Except for one big problem. ConTeXt (current lmtx from 2020.05.18 16:50) sometimes has problems to make a page break. And I get the weird result shown on the attached screenshot. After the page break the text of the section does not continue. Instead a number is shown. In the log file I can't find something suspicious. When I compile the source with current context (2020.01.30 14:13) I get something like an infinite loop. ConTeXt hangs and has to be killed with kill pid, Ctrl-C in terminal does not work So, in my opinion my layout or setup causes a bad situation, where ConTeXt does not know where to make a page break. While context hangs and warns me, lmtx runs smoothly but places a number in the text, which is bad as I might overlook it. I tried to make mwe but I cannot reproduce the error. Any ideas to improve my setup? Is this a bug or the intended behaviour? juh

chapter numbers
by jbf 08 Jun '20

08 Jun '20

I am attempting to get the word 'Chapter' to appear in the Chapter title, followed by its number, and I attempted to do it simply with: \setupheadtext[chapter=Chapter] \setuphead [chapter] [header=empty] What I get is simply the number, e.g. 1 My first chapter, 2 My second chapter etc. \setupheadtext is being ignored. What am I doing wrong? Julian

use parentheses in itemize
by Mike Cooper 08 Jun '20

08 Jun '20

Hello list. Here is the first what will no doubt be many *VERY* basic questions. So far, I am having quite a difficult time finding any help in the documentation (not just this issue but pretty much anything, really). Anyway, I want to have a list like this: (a) 415,668 lb (b) 440,668 lb (c) 517,000 lb (d) 542,000 lb How do I get these parentheses with my itemization symbol? THANKS!

problem since previous versions
by Hans van der Meer 07 Jun '20

07 Jun '20

A problem has arisen up since previous versions, where code without a problem now raises an error. This is the afflicted code: % Assign values to \locationbox. \doif{top}{\placexlocation}% {\def\startlocationbox{\vtop\bgroup\vss}}% \doif{center}{\placexlocation}% {\def\startlocationbox{\vcenter\bgroup}}% \doif{bottom}{\placexlocation}% {\def\startlocationbox{\vbox\bgroup}}% And it is used here: \setbox\placexbox=\startlocationbox \ignorespaces Previously this worked without a hitch, now the error is: tex error > tex error on line 9 in file ./familie-events.tex: ! A <box> was supposed to be here <to be read again> \vcenter \startlocationbox ->\vcenter \bgroup \dostartcontentplacexinline ...ables \par \setbox \placexbox =\startlocationbox \ignorespaces <to be read again> \syst_helpers_single_empty_one_nop \xmlflush \21>:xmlplc:placexcontent ...le=\xmlatt {#1}{alttitle}]}\startcontent \xmlflush {#1}\stopcontent l.9 } I can try to make a minimal example, but not without the afflicted module of some 800 lines. So perhaps the problem will be located by the experts at first sight. It is of course the \vcenter playing havoc, because replacing it by \vtop or \vbox makes the error disappear. Thanks for looking into it, because my work more or less depends on this code working in good order. dr. Hans van der Meer

errors in margindata?
by Hans van der Meer 07 Jun '20

07 Jun '20

I gues there are errors in \margindata. See the minimal example. The contextversion is fresh loaded just before this test. (1) \margindata{test} gives an error. The log message is: tex error > tex error on line 9 in file ./margindata.tex: ! Use of \typo_margins_data_yes doesn't match its definition l.9 \margindata{ text1}% One has to use \margindata[]{test} to avoid the error. (2) \margindata[]{test} has spurious whitespace, \margindata[]{test}% must be used to avoid that. Below the minimal example and the output. met vriendelijke groet dr. Hans van der Meer

Setup left, right, between entries in custom cite of multiple references
by Mike O'Connor 07 Jun '20

07 Jun '20

I'm trying to customise \cite and unable to get inbetween= to appear between entries in a multi-ref citation. My own customisations via a copy of publ-imp-apa.mkvi and .lua have this problem, so in case it was due to my customisation I went back to solid ground — the Chemistry example, pp. 70-74 in the Publications manual (http://pragma-ade.nl/general/manuals/mkiv-publications.pdf) The cite examples on p.74 work as shown, but when I add each of the following: \cite [name][108-95-2,566-33-5]\par \cite [formula][108-95-2,566-33-5]\par \cite [chemical][108-95-2,566-33-5]\par \cite [molarvolume][108-95-2,566-33-5,24599-57-3]\par I simply get the citation details, no separator between, and no left or right. Either of the following works for left= and right=. However inbetween= does not activate, and similarly for separator:2, separator:3, separator:4. \definebtx [chemistry:cite:formula] [left={\color[blue]{(}}, % the colour to differentiate from \setupbtx below right={\color[red]{)}}, inbetween={\btxcomma\btxspace}, % no effect ] \setupbtx [chemistry:cite:formula] [left={(}, right={)}, inbetween={\btxcomma\btxspace}, ] Grateful for any guidance as to how I can remedy this issue. Regards, and thanks, Mike

Two issues with respect to sections in ConTeXt
by Jairo A. del Rio 06 Jun '20

06 Jun '20

First: I made the following question wrt swapping section labels and section numbers: https://tex.stackexchange.com/questions/547761/how-to-swap-section-labels-a… What I tried to do is the following section structure 1. Chapter (Name of chapter) 1. 2 Section (Name of section) Wolfgang Schuster offered the following solution for chapters in Spanish, thanks :) \setuplabeltext[es][chapter={, capítulo}] However, I asked if there is a way to use predefined section labels according to chapters, sections, parts, etc. e.g. Chapter (EN) or Capítulo (ES) without manually writing a \setuplabeltext for every language, so he suggested that I move my question here and there we are. Second: The TeX command \S (section mark) seems to be insensitive to font size commands. I've tried with \setuphead[section][sectionstarter=\S] And the sign is smaller than the surrounding letters. I thought it was a matter of font design, but I've tried \setuphead[section][sectionstarter=§] And it worked. My question is: why? Is it a bug or a feature with respect to \S? I'm using ConTeXt MKIV version 2020.05.25 23:39 with LuaTeX Thank you in advance Jairo :D
