issue when the encapsulation ‘startitem stopitem’ command is in another self-defined command
by autumnus 29 Dec '24

hi, I'm creating a command that can format multiple choice questions on my own. I've done most of it at the moment. But I want more, so I'm trying to create more versions of this command that is already nearing completion. So I'm using the following command to create a command with more possibilities. I've noticed that ‘startitem stopitem’ isn't working. Their location and serial number are anomalous. %%%% Removed some unnecessary commands to show what the problem was. % macros=mkvi \starttext \unprotect \installnamespace {chitem} \installcommandhandler \????chitem {chitem} \????chitem \appendtoks \setuevalue{\e!start\currentchitem}{\startnamedchitem [\currentchitem]}% \setuevalue{\e!stop \currentchitem}{\stopnamedchitem}% \to \everydefinechitem \tolerant\protected\def\markedchoice#1{{\sym{@} \red sym : #1}} \tolerant\protected\def\normalchoice#1{\startitem normal : #1\stopitem} \tolerant\protected\def\\calc_maxwidth#1{} %The longest option text is calculated by comparison to % determine the number of columns that can be typeset \tolerant\protected\def\startnamedchitem[#chitem]#*[#mark]#*[#option]#*#choice\stopnamedchitem% {\begingroup % \ifarguments 0\or :1\or +2\or =3\or !4\fi \def\currentchitem{#chitem}% \edef\p_correctmark{*}\edef\p_paramark{#mark}% \calc_maxwidth{#choice}% \ifx\p_paramark\p_correctmark \markedchoice{#choice}% \else \normalchoice{#choice}% \fi\endgroup} \def\stopnamedchitem{} \definechitem[chitem] \protect \startitemize[n,horizontal,two]% % The process of calculating the number of formattable columns % has been removed and the results of the calculations are used directly. \startchitem xxx\stopchitem \startchitem[*]correct choice\stopchitem \startchitem xxx\stopchitem \startchitem xxx\stopchitem \stopitemize \stoptext %%%%% thanks for any help, autumnus

No problems with this versions: current version: 2023.02.07 19:06 current version: 2024.04.01 08:59 Were there changes how we have to treat environment files? The error only occurs when I use "--mode=trimsize" but I cannot track down the error by removing environments with mode-specific definitions. The first environment file does not contain any mode-specific definitions. Any hints? TIA juh

Hi, I am making a table using \starttabulate … I want row expansion last 3 columns and put a title “q” at the center of last 3 clolumns. I \NS[3][c] following the example in the wiki. However, it doesn’t work. The following code run without error message, but “[3][c]” appeared at the beginning of the first row in the output. How can I do that? Thank you. Best regards, Dalyoung

Issues with included images on some epub readers
by Florent Michel 28 Dec '24

28 Dec '24

Hi, I'm not sure whether the following is an issue with ConTeXt or with the epub readers I'm using; my apologies for the noise if it's not relevant to this list! I was experimenting creating ebooks with ConTeXt, and found it works very well on most epub readers (except with Calibre, as was previously reported on this list) as far as text is concerned, although I am having issues displaying images. Images appear correctly in the exported html file when opened with Firefox or Chromium, so I suspect the issue may either come from difference in specs for the epub and html formats or from bugs in the epub readers I have tried (Mupdf, Koodo, and Foliate). Example showing the issue: _____________________________________ % test.tex \setupbackend [export=yes] \setupinteraction [title={\documentvariable{title}}] \startdocument[title=Test EPUB] % Some text \samplefile{tufte} % Include a simple MetaPost image \starttextdisplay \startimage \startMPcode fill fullcircle scaled 3cm withcolor darkred ; \stopMPcode \stopimage \stoptextdisplay % Some text again \samplefile{tufte} % Include an equation as SVG image \starttextdisplay \startimage \startformula e = \frac{m c^2}{\sqrt{1 - v^2 / c^2}} \stopformula \stopimage \stoptextdisplay \stopdocument _____________________________________ I compile it using _____________________________________ mtxrun --script epub --images test.tex context test.tex mtxrun --script epub --make test.tex _____________________________________ Render from Koodo 1.5.1 (correct): https://pasteboard.co/4bUcUdaJim9m.png Render from Koodo's latest version (1.7.2): https://pasteboard.co/xRfDCYx9zki4.png All recent epub readers I have tried (Mupdf, Foliate, Okular) produce a similar incorrect rendering. I am not very familiar with the epub format specs so I don't have a good feel for where the issue may come from. It seems that manually adding <img alt="image-1" src="../images/test-exported-1.svg"> in the .html file makes it appear with recent epub readers, though. Is it possible to have the html output generated by ConTeXt include images in this way (or tune the way images are included in another way which may work better with recent epub readers)? Cheers, Florent

Run-in heading problem with \startparagraph and empty lines
by Rik Kabel 27 Dec '24

27 Dec '24

Hello list, Why is an empty after \startparagraph treated differently when the \startparagraph directly follows a heading with alternative=text than when there is no heading before, or a different type of heading, as shown in the following example? \setuphead[section] [alternative=text, style=\it] \starttext \startsection[title=Run-in heading] \startparagraph Works with no blank after \tex{startparagraph} \stopparagraph \stopsection \startsection[title=Run-in heading] \startparagraph Fails with a blank after \tex{startparagraph} \stopparagraph \stopsection \stoptext With every other heading alternative there appears to be no difference in the output. -- Rik

How to get enumerated tables to line up with the left edge of text?
by Joel 27 Dec '24

27 Dec '24

I created this simple example to show, when I add enumerations to my tables, its indenting the content. How can I stop this indentation from happening? I want the numbering to be consistent with the other numbers in my document, not indented. --Joel Example below: \starttext \input knuth % notice that the numbers line up with the text to the left \startitemize[n] \startitem test\stopitem \startitem test2\stopitem \stopitemize \input knuth % notice that the text in this table lines up with the text to the left \starttabulate[|p|p|p|] \NC test \NC info \NC details \NC\NR \NC test 2 \NC info \NC details \NC\NR \stoptabulate \input knuth % notice the numbering is indented from the left, no longer lines up \startitemize[n] \starttabulate[|p|p|p|] \NI test \NC info \NC details \NC\NR \NI test 2 \NC info \NC details \NC\NR \stoptabulate \stopitemize \input knuth \stoptext

Why isn't font changing inside tabulate environment?
by Joel 27 Dec '24

27 Dec '24

I need to make a symbol, checkmark, appear inside a table. It is from a different font. If I use this, it displays the checkmark in the document: {\switchtobodyfont[garamondsymbols, 12 pt]✔} But inside a tabulate environment, it stops displaying the checkmark. Is there any solution for this? \starttabulate[|p|p|]\NC{\switchtobodyfont[garamondsymbols, 12 pt]✔} \NC \NC\NR\stoptabulate --Joel

[ extra line in last tabulate column ]
by vm 24 Dec '24

24 Dec '24

if the last column of a tabulate table is a paragraph, an extra blank line is added at the top, making the last column not align. adding data in the last (non) paragraph column, will make them top align correctly. 8<--- \starttext \starttabulate[|p|p|p|l|][width=\textwidth, split=yes,margin=2mm, align=right] \dorecurse{3}{ \dorecurse{3}{ \NC Lorem ipsum dolor sit amet, consectetur adip iscing elit. Curabitur massa turpis, semper quis fringilla ut, viverra nec risus. }% <<< no data here \AR } \stoptabulate \page \starttabulate[|p|p|p|l|][width=\textwidth, split=yes,margin=2mm, align=right] \dorecurse{3}{ \dorecurse{3}{ \NC Lorem ipsum dolor sit amet, consectetur adip iscing elit.

playing with dates
by Pablo Rodriguez 23 Dec '24

23 Dec '24

Dear list, I would like to be able to design some calendars. Is there any way to have a command (Lua or ConTeXt) that can increase or decrease a given date by days (something like \nextday or \previousday). I have tried \date and \increment or \decrement, as shown in the wiki: \starttext Today is \currentdate. \dorecurse{25} {\increment\normalday} Tomorrow will be \currentdate. \decrement\normalday %\increment\normalmonth% -- gives an error \increment\normalyear And today in a year will be \currentdate. \stoptext But the main problem is that I end up having the improbable day of December 41st, 2024 (with \decrement\normalday, it would read -9th). Besides, \normalmonth cannot be incremented or decremented (although this would be useless for me). Is there any way to get a command that can increment or decrement by days a given date? Many thanks for your help, Pablo
