Bug with \startnarrow?
by denis.maier＠unibe.ch 04 Mar '23

04 Mar '23

Hi, While doing some more tests with my example from yesterday (tables in \startnarrow), I've realized that the example from the wiki doesn't seem to quite work as expected: %%%%%%%%%%%%%%%%%% \starttext Some text before \startnarrow[left=2cm,right=1cm,before={\blank[2*line]},after={\blank[halfline]}] narrower text \stopnarrow some text after \stoptext %%%%%%%%%%%%%%%%%% Already here, the extra margins on both sides seem to be equal. Changing the size of the left extra margin has no effect at all. %%%%%%%%%%%%%%%%%% \starttext \startnarrow[left=10cm,right=2cm] \input ward \stopnarrow but: \setupnarrower[left=5cm, right=2cm] \startnarrower[left,right] \input ward \stopnarrower \stoptext %%%%%%%%%%%%%%%%%% Is this a bug or intended behaviour ? Best, Denis

Disappearing footnote in figure / tabulate
by denis.maier＠unibe.ch 02 Mar '23

02 Mar '23

Hi, I have a strange case where a footnote in a tabulate disappears. Strangely, I *cannot* reproduce the behaviour in the MWE below. At first, I thought it must have something to do with \startpostponingnotes, but it seems that this currently isnt't necessary anymore, or at least only for extreme tables. Is that correct? I'll try to narrow it down. Any hints how I could debug that issue? As I'm again working with XML files: Is it possible that this behaviour is caused by some sort of nested setups which makes the footnotes not bubble up? Best, Denis \startbuffer[test] <?xml version='1.0' standalone='yes?> <document> <figure> <table> <tr> <td>a<footnote>2</footnote></td> <td>b</td> </tr> </table> </figure> <figure> <table-wrap> <table> <tr> <td>a<footnote>2</footnote></td> <td>b</td> </tr> </table> </table-wrap> </figure> </document> \stopbuffer \startxmlsetups xml:test \xmlsetsetup{\xmldocument}{document|table-wrap|table|figure|p|footnote}{xml:*} \stopxmlsetups \xmlregistersetup{xml:test} \startxmlsetups xml:document \xmlflush{#1} \stopxmlsetups \startxmlsetups xml:p \xmlflush{#1}\par \stopxmlsetups \startxmlsetups xml:footnote \footnote{\xmlflush{#1}} \stopxmlsetups \startxmlsetups xml:figure \startplacefigure[title={Test},location={force,split}] \xmlflush{#1} \stopplacefigure \stopxmlsetups \startxmlsetups xml:table-wrap \startpostponingnotes \xmlflush{#1} \stoppostponingnotes \stopxmlsetups \startxmlsetups xml:table \startpostponingnotes \starttabulate[|p|p|] \xmlfilter{#1}{/tr/command(xml:table:tr)} \stoptabulate \stoppostponingnotes \stopxmlsetups \startxmlsetups xml:table:tr \xmlfilter{#1}{/td/command(xml:table:tr:td)}\NC\NR \stopxmlsetups \startxmlsetups xml:table:tr:td \NC \xmlflush{#1} \stopxmlsetups \starttext \xmlprocessbuffer{test}{test}{} \startplacetable \starttabulate[|p|p|] \NC a\footnote{3}\NC b\NC\NR \stoptabulate \stopplacetable \startplacetable \bTABLE \bTR \bTD One\footnote{4} \eTD \bTD two \eTD \eTR \bTR \bTD One \eTD \bTD two \eTD \eTR \eTABLE \stopplacetable % \startpostponingnotes \startplacetable \startxtable \startxrow \startxcell a\footnote{5}\stopxcell \startxcell b\footnote{6}\stopxcell \stopxrow \stopxtable \stopplacetable % \stoppostponingnotes \stoptext

Float control
by denis.maier＠unibe.ch 02 Mar '23

02 Mar '23

Hi everyone, I've recently had to typeset a document that gave me some headaches with the floats. The floats where jumping around, appearing in a different order than in the source file, tables ended up split up at weird points, some positioning keys had not the intended effect (e.g. top), <page> moved the float more than seemed necessary for me... I know, TeX's float positioning algorithm should be rather reliable and stable, and it's quite possible that I'm messing things up in my setups-especially since my source files are XML. Anyway, I'd like to learn more about the whole float issue. Is there anything particular I could read to learn more about the whole thing? Maybe I'm missing out on something fundamental... Best, Denis

How to place a page reference multiple times?
by Joel 02 Mar '23

02 Mar '23

I need to report every chapter that a particular macro appeared. I would do this by placing `\pagereference[sample]` inside the macro definition, so whenever it is called, it marks the reference info. But I can't seem to get references to work with multiple reference locations marked, example: \starttext You can find it at \at{page}[sample] in \at{chapter}[sample]. \chapter{Fish} \pagereference[sample] \input knuth \input knuth \pagebreak \chapter{Whales} \input knuth \pagereference[sample] \stoptext (you can see in this example, it only finds `\pagereference[sample]` on page 1 and ignores the second appearance. Ideally, I need to be able to output something like, "See examples in Chapter 3, 8, 19" (because those chapters contain a particular macro that I marked with \pagereference. Or, if even possible, see chapters 3 (p. 22), 8 (p. 40), and 20 (though the first example is fine. Is there a way to place a page reference multiple times, so multiple pages or chapter details will appear? --Joel

/CropBox overflows /MediaBox
by Pablo Rodriguez 01 Mar '23

01 Mar '23

Dear list, I have the following source: \nopdfcompression \setupinteractionscreen [width=max] \setuplayout [standard] [backspace=.7\textwidth, cutspace=\cutspace, width=middle] \starttext \startmakeup[page] \null \stopmakeup \startmakeup[standard] \null \stopmakeup \stoptext Boxes are defined in the following objects: 3 0 obj [ 0 0 595.275590072 841.88975789 ] endobj 5 0 obj [ 0 0 595.27559 841.889758 ] endobj 8 0 obj [ 0 0 968.199847 841.889758 ] endobj Page 1 has /MediaBox redirected to object 3 and /CropBox redirected to object 5. Page 2 has /MediaBox redirected to object 3 and /CropBox redirected to object 8. I’m not sure whether the oversized /CropBox in the sample above is a bug triggered by the use of "\setupinteractionscreen[width=fit]". >From the PDF–1.7 specification (https://opensource.adobe.com/dc-acrobat-sdk-docs/standards/pdfstandards/pdf…) The crop, bleed, trim, and art boxes shall not ordinarily extend beyond the boundaries of the media box. If they do, they are effectively reduced to their intersection with the media box. https://wiki.contextgarden.net/PDF_Boxes displays an image of (what I guess) the ordinary case: /CropBox fits inside /MediaBox. Could anyone be so kind to confirm the issue or to explain the rationale behind the oversized /CropBox? Many thanks for your help, Pablo

\setupparagraphs - can they run over two pages?
by jbf 27 Feb '23

27 Feb '23

I have the following setup for side-by-side paras. \defineparagraphs[Two][n=2] \setupparagraphs[Two][1][width=.1\textwidth,style=\bfx,align=tolerant] \setupparagraphs[Two][2][width=.9\textwidth,style=normal,align=tolerant] My difficulty is that while there is only ever just a couple of numbers in the left-hand 'column', the right-hand 'column' may have several lengthy paragraphs. If I have one relatively short \startTwo followed by one that is much longer, it will be forced to start on the next page, leaving too much empty space on the previous page. It is probable that getting this environment to split across pages is not possible. I can try very different approaches (columns, tables) to solve my problem, but I thought I would at least ask first. Julian

Aaligned numbers in a matrix?
by Bruce Horrocks 27 Feb '23

27 Feb '23

I'm using the following MWE to produce a matrix: \definemathmatrix[bmatrix] [matrix:brackets] [simplecommand=bmatrix] \starttext $ a \rightarrow \bmatrix{1, 2, 3, 4; 2, 1, 4, 3; 3,-4, 1,-2; 4,-3, 2,-1} $ \stoptext The columns with negative numbers in are centred and I would rather have them right-aligned so that the digits stack up above each other and the negative signs stick out to the left, so to speak. Is there an easy way to achieve this? — Bruce Horrocks Hampshire, UK

How to add data from another PDF in index?
by Joel 26 Feb '23

26 Feb '23

I am making a textbook and workbook set. I have this custom index using this code, in both the textbook and workbook: % \defineregister[learnedshort][compress=yes] \setupregister[learnedshort][style=sansbold, textstyle=slanted, n=2, pagenumber=yes, indicator=no] % \defineregister[learnedlong][compress=yes] \setupregister[learnedlong][style=sansbold, textstyle=slanted, n=2, pagenumber=yes, indicator=no] % \define[1]\learnedis{% \txt{} \getvalue{#1} \learnedshort{#1} \learnedlong{#1} } \define[1]\learned{% \learnedshort{#1} \learnedlong{\getvalue{#1}} } \starttext \learnedis{blah blah} \input knuth \learnedis{some more} \startchapter[title=Standards] \placelearnedshort \stopchapter \stoptext My question is, can I have references to the Workbook page numbers in the textbook? And visa-versa? For instance, the Textbook index currently looks like this: ------------- Standards blah blah 1 some more 2 -------------- With the data in the Workbook it might look like this: Standards blah blah 1, WB: 1, 3-8 some more 2, WB: 8-9 yet more WB: 10, 12 -------------- Is this possible to merge index information like this? --Joel
