I would like to change the width of the margins on the page. In the MWE here, the pagelayout does not seem to obey the \setuplayout command. Why are the margins shown uneffected by \setuplayout? yours sincerely dr. Hans van der Meer

unwanted blank page
by Hans van der Meer 03 Dec '23

03 Dec '23

I should have a first page without pagenumber and pagenumbers on the subsequent ones. However the MWE here introduces an unwanted blank page from the call to \setuppagenumbering[state=start]. And the \setuppagenumbering has to come after the \page, of course. Should I program otherwise? yours sincerely dr. Hans van der Meer % test pagenumbering start-stop \setuppapersize[A5][A5] \starttext \setuppagenumbering[state=stop] \ConTeXt\space\contextversion\blank This is page 1 without pagenumber.\crlf \page \setuppagenumbering[state=start] This should be a page with pagenumber 2.\crlf But the pagenumber is 3 instead after blank page 2. \stoptext

mathalignment; alignment of columns
by wolfgangbackes＠mail.de 28 Nov '23

28 Nov '23

Something as elementary as "mathenvironment" can't really be faulty, can it? According to my recent tests, a mathalignment environment does not seem to react (any more) to the values of the "align" option. The source code hab been rendered correctly a few years ago, Minimal example 1: \starttext \startformula \startmathalignment[n=2,align={left, right}] \NC always aligned to the right \NC = u + at, \NR \NC d \NC = ut + \frac12 at^2. \NR \stopmathalignment \stopformula \stoptext Despite "align={left, right}", the first column is aligned to the right and the second to the left. This does not change, no matter which values I assign to "align", for example align={middle, middle}. The align option is also ignored in the case of other column numbers., for example: \starttext \startformula \startmathalignment[n=1,align=left] \NC This single column should \NR \NC be left-aligned, \NR \NC but it is centered. \NR \stopmathalignment \stopformula \stoptext What am I missing here? Where is my mistake? Regards Wolfgang

Converting XHTML captions to ConTeXt captions
by Thangalin 26 Nov '23

26 Nov '23

I'd like to capture a caption and apply it to the block-level element that immediately follows. In the MWE, is there a more "ConTeXt way" to accomplish the task of adding captions to tables, figures, blockquotes, etc? % SOT \startbuffer[demo] <body> <p><span class="caption">Caption 1 <a data-type="tbl" name="lbl-1"/></span></p> <table>table 1 with caption</table> <table>table 2 without caption</table> <p><span class="caption">Caption 3 <a data-type="tbl" name="lbl-2"/></span></p> <table>table 3 with caption</table> </body> \stopbuffer \startxmlsetups xml:demo \xmlsetsetup{\xmldocument}{*}{-} \xmlsetsetup{\xmldocument}{a|p|body|table}{xml:*} \xmlsetsetup{\xmldocument}{span[@class='caption']}{xml:span} \define\CaptionText{} \define\AnchorXref{} \stopxmlsetups \startxmlsetups xml:span \define\CaptionText{\xmlflush{#1}} \stopxmlsetups \startxmlsetups xml:a \define\AnchorXref{\xmlatt{#1}{data-type}-\xmlatt{#1}{name}} \stopxmlsetups \startxmlsetups xml:body \xmlflush{#1} \stopxmlsetups \startxmlsetups xml:p \xmlflush{#1}\par \stopxmlsetups \startxmlsetups xml:table \blank \doifelsetext{\CaptionText}{% \startplacetable[ title={\ignorespaces\CaptionText{}\removeunwantedspaces.}, reference={\AnchorXref} ] \define\CaptionText{} \define\AnchorXref{} }{ \startplacetable } \startembeddedxtable \startxtablebody[body] \startxrow \startxcell \xmlflush{#1} \stopxcell \stopxrow \stopxtablebody \stopembeddedxtable \stopplacetable \blank \stopxmlsetups \xmlregistersetup{xml:demo} \starttext \xmlprocessbuffer{demo}{demo}{} \stoptext % EOT

Compatibility Issue with TikZ/Spy Library in ConTeXt: Seeking Solutions
by wolfgangbackes＠mail.de 24 Nov '23

24 Nov '23

Hello, I am reaching out to seek assistance regarding a compatibility issue I have encountered after installing ConTeXt on a new computer. The problem arises when attempting to compile documents that utilize the spy library; the LuaTeX engine returns the following error message: "error (luacall): invalid number mtx-context | fatal error: return code: 1" Unfortunately, the error message provides no additional clues. To investigate further, I created a minimal example, which you can easily verify at https://context-on-web.eu/. The example employs the spy library within a TikZ environment. Surprisingly, the same example runs without error on my local LaTeX engine, indicating a potential compatibility issue between ConTeXt and the spy library. Here is the minimal example for your reference: \starttext \usemodule[tikz] \usetikzlibrary {spy} \starttikzpicture[spy using overlays={size=12mm}] \draw (0,0) -- (1,1) -- (2,-1); \spy [blue,magnification=5] on (1,1) in node at (3,0); \stoptikzpicture \stoptext I am curious if anyone else has encountered a similar problem with the spy library and ConTeXt and, if so, if there is a known solution. Any insights or guidance would be greatly appreciated. Thank you for your time and assistance. Best regards, Wolfgang Backes

It works after a few changes but ..
by Ursula Hermann 23 Nov '23

23 Nov '23

Dear List, After a few changes i have here an example: It works, but what I wanted to know is why are there round brackets after writing \starttheroem if i compile it. Should be without round brackets. I have the following example, the text was in a PDF from 2008, called: Theorems in ConTeXt, and also my text with the margin: \definemargindata [MyInMargin][inright] \definemarginframed[MyInMargin][topframe=on,bottomframe=on,rulethickness=1pt,width=1cm] \margintext{\blackrule[color=black, height=0.25ex, width=1cm]\\}\blackrule[color=black, height=0.25ex, width=7cm] \setupenumerations [ before={\blank[big]}, after={\blank[big]}, location=serried, width=broad, distance=0.5em, headstyle=bold, titlestyle=normal, way=bytext, conversion=numbers] \defineenumeration [theorem] [ text=Theorem, title=yes, style=italic, list=all, listtext={Theorem }] \starttext \margintext{2.1.1}{\starttheorem {The square on the hypotenuse is equal to the sum of the squares on the other two sides. Ach is das schön, dass du da bist} \stoptheorem \stoptext Maybe someone can help me.

externalfigure crashed
by Hans van der Meer 22 Nov '23

22 Nov '23

When \externalfigure could not find the file it used to graciously place a rectangle kindly telling the user that the file has not been found. But now, however, it seems the default in this case is a crash. Very annoying in comparison with the earlier behaviour. I might make a mistake, but the MWE is as simple as can be. The filename is test.jpeg, then this runs ok: \starttext \externalfigure[test.jpeg][] \stoptext But this crashes, see the log: \starttext \externalfigure[test.jpg][] \stoptext yours sincerely dr. Hans van der Meer
