\definelayout[pagenumber][layout] behaving strangely
by peter.hopcroft＠icloud.com 09 Dec '22

09 Dec '22

The pdf from the tex below looks wrong to me, screenshot attached. It’s always like this when the page number in the second \definelayout is 1 more than the page number in the first. For other pairs of numbers, it behaves like I expect: the short layout is only on those 2 pages. I’m using the LMTX I updated a few days ago. ConTeXt online’s pdf is the same. %====================================================== \showframe \setuppapersize[A4][A3,landscape] \setuparranging[2SIDE] \setuplayout[backspace=80mm, width=100mm, topspace=50mm, header=0mm, footer=0mm, height=200mm, margindistance=10mm, leftmargin=40mm] \definelayout[short][backspace=80mm, width=100mm, topspace=50mm, header=0mm, footer=0mm, height=80mm, margindistance=10mm, leftmargin=40mm] \starttext \definelayout[2][short] \definelayout[3][short] \dorecurse{10}{\input{knuth} } \stoptext %====================================================== Also, https://wiki.contextgarden.net/Command/definelayout says: % different layout for first two pages \definelayout[1][wide] \definelayout[3][reset] This does not work for me. Cheers, Peter

Achieving different \cite styles
by Jethro Djan 09 Dec '22

09 Dec '22

Hello everyone I am interested in being able to cite in different ways. By analogy, I refer to the \texcite{}, \parencite{} and other options available with biblatex in LaTeX. How do I achieve something like \textcite{} in ConTeXt? Here is my MWE: \startbuffer[ref] @Article{wn:2017, author = {Who, Nobody and What, Everyone}, journal = {Good Journal}, title = {The Art of Being}, year = {2017}, } \stopbuffer \definebtxdataset[ref] \usebtxdataset[ref][ref.buffer] \setupbtx[ dataset=ref, ] \definebtxrendering [ref] [apa] [ dataset=ref, ] \usebtxdefinitions[apa] \starttext In \cite[wn:2017], they illustrated that it is impossible to not be them. \cite[wn:2017] said it was worth the discovery. \startsection[title={References}, number=no, incrementnumber=no] \placelistofpublications[ref][method=dataset] \stopsection \stoptext The first sentence is okay. In the second, I would like the parenthesis around the citation to come off because of the way I am citing it. Jethro

\hpos in math
by Gavin 08 Dec '22

08 Dec '22

Hello List, I am working on a project which combines graphics with formulas, like this: My code for creating this formula is attached. It works well, but I have a couple of questions that could make it work better. 1) Is there a mathematics version of \hpos? The contents of \hpos are set as text, even when \hpos is in mathematics, so I wrote an \mpos macro that uses \hpos but sets the contents as display-style math. This isn’t great for spacing, and it does't adapt to different math styles. \framed has a math version, \mframed, that sets the contents in the appropriate math style. If anyone know a way to accomplish that with \hpos, I’d love to know. 2) Is there a way to limit the scope of the \hpos labels to a single formula. This could turn into a book length project, with several formulas per page and several connections per formula. If every \hpos in the entire book needs a unique identifier, I could go mad. Under no circumstances will I connect one formula to another, so I’d like to be able to use something like \hpos{A}{…}…\hpos{B}{…} in each formula. Any suggestions? I’ve got to say, LMTX is an absolutely amazing tool for this project, which includes complicated networks of connections above and below many formulas. The integration of TeX, MetaPost, and Lua makes this project tremendous fun. Thanks! Gavin P.S. For the curious, I’m using a method for doing General Relativity based on spinors rather than tensors, following the methods of Penrose and Rindler in their 1985 books “Spinors and Space-time.” In the typesetting example above, the e_\alpha and e_{\dot\beta} are basis spinors (one left-handed, one right-handed). The e^\mu is the Infeld-van der Waerden symbol relating the spin basis to the coordinate basis. The connections are spinor index contractions. The formula above relates the components of the Infeld-van der Waerden symbol to the Pauli sigma matrices. This relationship only works in flat space, so this is an easy example! [Penrose and Rindler, vol 1 p. 125]

Hello list, The following fails with ConTeXt ver: 2021.10.24 21:45 MKIV but works with the companion LMTX. The error message is:tex error > tex error on line 6 in file G:/TestConTeXt/convert.tex: !

How to display the pages of a particular section in another PDF?
by Joel 06 Dec '22

06 Dec '22

I can use this code to display page 5 from a PDF:\externalfigure[filename.pdf][page=5]I am making a teacher's guide for a workbook (workbook.pdf). I need to be able to display on the page all pages of a particular section. The teacher's guide uses the same section titles as the workbook, e.g.: 17-A: Title 17-B: Title In other words, there is 1:1 pairing of section titles in the teacher's guide and the workbook. Is there any way to tell ConTeXt to display all of the pages for a particular section? \externalfigure[filename.pdf][section=17A] --Joel

\externalfigure problem with displaying external images via https://live.contextgarden.net
by Jaroslav Hajtmar 05 Dec '22

05 Dec '22

Hello. A few years ago I created a PHP application for printing filled forms with PDF background. PHP application is generating ConTeXt source code, that is subsequently translated using the online application https://live.contextgarden.net. I have now discovered that the application is not functional because the https://live.contextgarden.net application is unable to retrieve the external PDF file from our organization's URL. Oddly, this source code at https://live.contextgarden.net does not generate a PDF file with the form in the background: \starttext \externalfigure[http://gyza.cz/iapp/opisvysv/498540_SS_16_predmetu_str1_PDF.pdf] % PDF FILE ON OUR ORGANIZATION (SCHOOL) HOSTING \stoptext This is despite the fact that the PDF file exists at the URL and the browser is able to display it. On the other side the source code: \starttext \externalfigure[http://hajtmar.cz/iapp/opisvysv/498540_SS_16_predmetu_str1_PDF.pdf] % PDF FILE ON MY PRIVAT HOSTING \stoptext or source code: \starttext \externalfigure[http://www.pragma-ade.nl/show-gra.pdf] % PDF FILE ON PRAGMA-ADE.NL WEB \stoptext without any problems will generate a correct PDF file. Does anyone know what the problem might be? Why online ConTeXt is not read my PDF file and on other side read another PDF file? What does onlineConText not like? I need to get my application for printing archive certificates working again... Thanks. Jaroslav

issue with OT feature in LMTX

Dear list, I have the following sample (using current latest from 2022.12.01 13:05): \definefallbackfamily[mainface][rm][Noto Emoji] [range={0x1F004-0xFE837}, force=yes] \definefontfamily[mainface][rm][TeX Gyre Pagella] \setupbodyfont[mainface] \definestructureconversionset [sectionnumbers] [0,n,Characters,g,n] [n] \definefontfeature[section] [smcp=yes, c2sc=yes] \setupheads[sectionconversionset=sectionnumbers] \setuphead[section][style={\feature[+][section]}] \starttext \section{Just text} {\feature[+][section]Just text} \stoptext LMTX outputs no small caps and it fallbacks to Noto Emoji. LuaTeX gives the right output. Am I missing something or have I hit a bug in LMTX? Many thanks for your help, Pablo
