LMTX/MkIV difference in date handling
by Henning Hraban Ramm 14 Jan '21

14 Jan '21

ConTeXt ver: 2021.01.11 17:27 LMTX fmt: 2021.1.11 The following works in MkIV, but not in LMTX: \def\Jahr{\currentdate[year]} \settaggedmetadata[ rights={© \Jahr{} Me} ] \starttext \strut \stoptext The error message is: 1 \def\Jahr{\currentdate[year]} 2 3 \settaggedmetadata[ 4 >> rights={© \Jahr{} Me} 5 ] 6 7 \starttext 8 \strut 9 \stoptext 10 You've closed more groups than you opened. Such booboos are generally harmless, so keep going. Hraban

Extra space in align if tagging is enabled
by Mikael Sundqvist 13 Jan '21

13 Jan '21

Hi, There is an extra vertical space after displayed formulas with align if pdftagging is enabled. If I remove the last \NR it goes away (but I have got the idea that one should have that final \NR there?) /Mikael \setuptagging[state=start] \starttext \samplefile{knuth} \startformula \startalign \NC A \NC = B\NR \stopalign \stopformula \samplefile{knuth} \startformula \startalign \NC A \NC = B \stopalign \stopformula \samplefile{knuth} \stoptext

extra width in cropbox and trimbox
by Pablo Rodriguez 12 Jan '21

12 Jan '21

Dear list, I have already reported this before (https://mailman.ntg.nl/pipermail/ntg-context/2020/099636.html) I have the following sample: \setupinteractionscreen [width=fit] \starttext \null \stoptext Mediabox is fine: [ 0 0 595.2756 841.8898 ] But cropbox and trimbox contain extra width: [ 0 0 741.4331 841.8898 ] This is caused by \setupinteractionscreen[width=fit]. Generating booklets from documents with the values above leads to wrong output. Could anyone explain me what is wrong here? Sorry, but I don’t know what I may be missing. Many thanks for your help, Pablo -- http://www.ousia.tk

xtable as list item
by Pablo Rodriguez 12 Jan '21

12 Jan '21

Dear list, I have the following sample: \starttext \startitemize[n][margin=yes] \item a \item \startembeddedxtable[option={stretch, width}] \dorecurse{25}{\startxrow \startxcell \Characters{\recurselevel}\stopxcell \startxcell \characters{\recurselevel}\stopxcell \stopxrow} \stopembeddedxtable \stopitemize \stoptext I want to add the xtable as a list item. I’m experiencing two issues: 1. Item number is placed at the bottom of the xtable. 2. There is an added horizontal space, so that the xtable has a minimal indentation that the first item doesn’t have. (In my real document, this horizontal space is huge.) Is there any way to suppress both issues? Many thanks for your help, Pablo -- http://www.ousia.tk

lmtx upload
by Hans Hagen 11 Jan '21

11 Jan '21

Hi, I uploaded a new lmtx. Nothing spectacular as I'm still playign with compact font support (as explained in previous mails). Most seem to work now. New magic: \startTEXpage[offset=10pt] \vl\glyph `M\vl\quad \vl\glyph raise 3pt `M\vl\quad \vl\glyph left 3pt `M\vl\quad \vl\glyph right 2pt`M\vl\quad \vl\glyph raise -4pt right 4pt`M\vl\quad \vl\glyph left -1pt right -1pt`M\vl \stopTEXpage This is part of some experiments with manipulating glyph dimensions instead of font kerns. These extensions will stay (who knows when it comes un handy) but we will probably stick to font kerns as default. \startTEXpage[offset=10pt] \showfontkerns \showglyphs \strut average\par \vskip-2ex \enabledirectives[fonts.injections.method=advance] {\red \strut average}\par \stopTEXpage Both methods have their pros and cons.

Re: [NTG-context] A not so short introduction to ConTeXt Mark IV

One nice tool that I use for translation is https://po4a.org/index.php.en I used it to translate (and maintain) complete Vim documentation.

Math blackboard (bug?)
by Johann Birnick 09 Jan '21

09 Jan '21

To write blackboard math, the syntax was $\blackboard{N}$ , but now this also makes the rest of the text blackboard. So one has to use ${\blackboard N}$ . Is this indented? (the old way is a bit easier to use) Secondly, I want to address the blackboard font. Try out \starttext ${\blackboard NR}$ \stoptext This looks different then in the past. It doesn't have serifs. It looks like the wrong font, like sans. Is this a bug? To me it looks awful, honestly. It doesn't fit the rest of the math font at all. Best regards Johann

Math align not working
by Johann Birnick 09 Jan '21

09 Jan '21

Hi there, I noticed that Math align is not working properly. In particular I mean the alignment. For example, the following code \starttext \startformula \startalign[m=2,distance=8em,n=5, align={right,middle,middle,middle,left}] \NC 0 \NC < \NC 2x + 5y \NC < \NC 10 \NC 4 \NC < \NC 3x + y \NC < \NC 9 \NR \NC 3 \NC < \NC 2y + 3z \NC < \NC 15 \NC 10\NC < \NC 8y + 5z \NC < \NC 20 \NR \stopalign \stopformula \stoptext is copied from https://dl.contextgarden.net/myway/mathalign.pdf but doesn't produce the intended result. What's wrong? Best regards, Johann

Weekdays and others as numbers
by Jairo A. del Rio 08 Jan '21

08 Jan '21

ConTeXt has some inbuilt functions for dates. I see that the following \mainlanguage[spanish] \starttext \dayoftheweek{4}{5}{1992} \stoptext gives "lunes" (Monday). How to get a weekday number (2 in this case) instead? Sincerely, Jairo
