Numbering in mathalignment not working
by śrīrāma 25 May '22

25 May '22

Hi, [I am on version 2022.05.11 11:36] I think either a bug might have crept into one of the recent uploads or there is some change in behaviour – numbering of statements inside mathalignment blocks is not working: only one statement is numbered even if multiple are requested. The following example does not produce the expected result (sample attached): both the equations should be numbered when only the first one is – \starttext \placeformula \startformula \startmathalignment \NC a \NC = b \NR[eq:one] \NC c \NC = d \NR[eq:two] \stopmathalignment \stopformula \stoptext Also the [+] options and the second optional argument of \NR does not work as expected. Has its behaviour changed? I ran into this when I compiled a large maths-heavy document and while proof- reading noticed numerous missing references to statements inside mathalignment. Please advise me on how I might fix/workaround this. Thank you, Sreeram

font question re U+00336
by jbf 25 May '22

25 May '22

I wonder if someone can help me interpret this message in the log file fonts > start missing characters: /home/jbf/bin/context/tex/texmf/fonts/opentype/public/tex-gyre/texgyrepagella-regular.otf fonts > 88 U+00336 ̶ COMBINING LONG STROKE OVERLAY fonts > stop missing characters My questions are as follows: 1. What does 88 mean here? 88 instances of this missing glyph? Page 88? Or something else? or in other words, how might I discover where something is missing from the original text? 2. Tex Gyre Pagella is normally a pretty handy typeface to use for me because it has pretty much all the glyphs I normally need... except this one obviously! Isn't it really just an en rule (or very similar to such)? Or in other words, how do I best overcome the problem of this missing character? 3. And perhaps connected with the above question: is there good fallback solution one can use? Do I need to \definefontfallback something or is there an automatic one already happening? I've started to examine the log files a bit more carefully for various items and it is showing up my ignorance!! Julian

How to add margin around standalone MetaPost?
by Vincent Hennebert 24 May '22

24 May '22

Take the following MetaPost file: beginfig(0) ahlength := 20; linejoin := mitered; drawarrow origin--(40,0) withpen pencircle scaled 5; endfig; Render it into PDF with ConTeXt. Witness the cut out ends of the arrow. How to fix that? Being able to add some margin would be a solution, which may be desirable anyway in some cases. Is that possible? Thanks, Vincent

XML Namespaces and XML Setups
by Christoph Reller 24 May '22

24 May '22

Dear List, Consider the following MWE: \startxmlsetups xml:demo:base \xmlsetsetup{#1}{tag}{xml:demo:tag} \stopxmlsetups \xmlregisterdocumentsetup{demo}{xml:demo:base} \startxmlsetups xml:demo:tag %\doif{\xmlnamespace{#1}}{o}{NameSpaceO:} \xmlflush{#1} \stopxmlsetups \starttext \startbuffer[test] <?xml version="1.0"?> <root xmlns="NameSpaceA" xmlns:o="NameSpaceO"> <tag>text</tag> <o:tag>text</o:tag> </root> \stopbuffer \xmlprocessbuffer{demo}{test}{} \stoptext My questions: - Is there a good way to have a separate XML setup for each XML namespace? - Alternatively, one has to do the distinction within the same XML setup. In this case, how do we get the complete namespace? (In this example: "NameSpaceA" and "NameSpaceO") Thanks in advance for your help! Cheers, Christoph

is \version[temporary] still alive?
by Steffen Wolfrum 22 May '22

22 May '22

Hi, testing this mwe I’d expect some indicators detecting overfull lines. At least on my machine (ConTeXt ver: 2022.01.21 20:13 LMTX) nothing happens: \setuppapersize[A6] % Tell ConTeXt where the windmill picture is \setupexternalfigures[location={default}] \version[temporary] \section{Slithy toves} % Top right of page will show successful reference '< fig2' % Left margin will mention unsuccessful reference 'figNothing->' See \in{Figure}[fig2] and \in{Figure}[figNothing]. % Top right of page will show new-created anchors '> fig1' and '> fig2' % Top right of page will show successfully placed floats \placefigure[here][fig1]{First windmill}{ \externalfigure[mill][width=1cm] } \placefigure[here][fig2]{Second windmill}{ \externalfigure[mill][width=1cm] } \startcolumns[n=3] % Overfull lines will have slugs in colum margins. \input linden % Underfull hboxes get no warning x \stopcolumns Steffen

Metapost examples seems broken
by Jan-Erik Hägglöf 22 May '22

22 May '22

HI! I have issues to access the very most useful place to get inspiration to write MetaFun code. Google Chrome reports security issues Maybe this could be off topic in this forum, if so, My apologize in advance. But maybe someone knows the author of this site https://tex.loria.fr/prod-graph/zoonekynd/metapost/metapost.html <https://tex.loria.fr/prod-graph/zoonekynd/metapost/metapost.html> /Jan-Erik

HI! How do I accomplish a similar funktion like this, that is written in latex, but in context instead? LATEXCODE \documentclass{article} \usepackage{hyperref} \begin{document} \begin{Form} \CheckBox[name=mycheckbox,checkboxsymbol=\ding{53}]{This is a check box:} \end{Form} \end{document} Thanks in advance Jan-Erik

ignore not closed tags in XML input
by Pablo Rodriguez 21 May '22

21 May '22

Dear list, I would like to feed https://seumasjeltzz.github.io/LinguaeGraecaePerSeIllustrata/001.html as XML input for ConTeXt. The problem is that (as many other XML files that I haven’t generated myself) some <meta> and <link> tags aren’t closed, such as in: <meta charset="utf-8"> <link href="https://fonts/css?greek" rel="stylesheet"> <link href="style.css" rel="stylesheet"> So, all that I get is the following message: invalid xml file - parsed text Unsuccessfully I have tried the following: \xmlsetsetup{#1}{html/head/(meta|link)}{-} Is there no way to make ConTeXt more tolerant, so that it is able to ignore those tags? Many thanks for your help, Pablo

MetaFun manual's "texvar" is not working for me
by Gavin 21 May '22

21 May '22

Hello list, I’m trying to reproduce the positional graphics examples in the MetaFun manual on pp. 151-153. There are two examples of code for the mpos:box. The first example uses \MPvar to retrieve variables set using \setupMPvariables. This works fine. The second example uses texvar to retrieve variables, but it does not work in the current LMTX. However, the second example does work with my TeXLive install. I’ve put my working example below, with both versions of the mpos:box code. Log output from a failed run is below that. Any ideas where I might be going wrong? Thanks!
