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

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

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!

can't accent/fake characters in euler font
by a badin 19 May '22

19 May '22

Hello all, typesetting accented characters in eulernova font does not seem possible to me. Is it really impossible? The other math fonts (stix/xits) do it. I'm using Context LMTX 2022.01.21 20:13 \starttext \switchtobodyfont[eulernova] \startlines euler: 1 - č 2 - \ccaron 3 - \v{c} \stoplines \switchtobodyfont[stixtwo] \startlines stix: 1 - č 2 - \ccaron 3 - \v{c} \stoplines \stoptext In the end I'd like to be able to make more custom characters, e.g. Ĺ, ô, ä, ... therefore I wanted to read about how those could be made, but the wiki points to missing files: http://source.contextgarden.net/enco-acc.tex http://source.contextgarden.net/tex/context/base/enco-def.tex Any help appreciated, Andrej Badin

overthinking overprinting
by Henning Hraban Ramm 19 May '22

19 May '22

A question on TeX-D-L reminded me to look into this subject. At the moment, there is \setupcolors[intent=overprint|knockout] with \startoverprint|knockout, as defined in colo-ext.mkxl|mkiv. I’m not sure what that does as a general setting – usually you need overprinting for black text and lines in CMYK documents. There are special cases where you want other (spot) colors to overprint, but that’s quite rare, and I can use transparency features to achieve the same (a=multiply) in an even more flexible way – as long as I don’t need a format like PDF/X-3 that doesn’t allow transparencies. If I declare such a format, ConTeXt just switches off transparencies and doesn’t try to emulate (“flatten”) them as e.g. InDesign does. So it would be nice if I could e.g. \definecolor[OPred][m=1,y=1,intent=overprint] OTOH there are cases where I want a black area or text to knockout the background, these might work with \startknockout etc. When I try my example: \useMPlibrary[dum] \setupcolors[ rgb=no,cmyk=yes, intent=overprint,% or knockout ] \setupbodyfont[modern,ss,18pt] \starttext \definecollector[Test] \setcollector [Test] {\externalfigure[none][width=8cm,height=6cm,frame=on]} \setcollector [Test] [corner=middle,location=middle] {{\bf Toast}} \setcollector [Test] [corner={left,top},location={right,bottom}] {\framed{LT}} \setcollector [Test] [corner={left,bottom},location={right,top}] {\framed{LB}} \composedcollector{Test} \stoptext ... then the text is “knocked out” regardless how set the intent. It also doesn’t help to use \startoverprint for the Text. The attached screenshot shows the color separation preview from Acrobat Pro 9. Is this broken or intended to be used differently? Hraban
