Seems to be a bug with \definelayout
by peter.hopcroft＠icloud.com 10 Dec '22

10 Dec '22

I’ve rewritten my last email. The context below produces the pdf in the screenshot below. I expect the layout[short] to be applied to pages 2 and 3. It is. But there seem to be 2 bugs: 1 - Pages 4, 5 and 6 have the [short] layout. They should have the default layout. 2 - On pages 5 and 6, the text flows beyond the bottom of the frame. It should stop at the bottom of the frame. Why do I think these are bugs? If I change the page number in \definelayout[3][short] to \definelayout[4][short], then it behaves differently and as I expect: only pages 2 and 4 have the [short] layout and the text flows within the frames.

extra hyphen in underscore hyphenation
by Pablo Rodriguez 10 Dec '22

10 Dec '22

Dear list, I have the following sample: \startluacode function document.addfunnyhyphen(tfmdata) local underscore = utf.byte("_") local char = tfmdata.characters[underscore] if not char then return end tfmdata.characters[0xFE000] = { width = 0, height = 0, depth = 0, commands = { { "right", -char.width }, { "down", char.depth }, { "slot", 1, underscore }, } } end utilities.sequencers.appendaction("aftercopyingcharacters", "after","document.addfunnyhyphen") \stopluacode \definehyphenationfeatures [underscore] [righthyphenchar="FE000] \sethyphenationfeatures[underscore]% \setuphyphenation[method=traditional]% \starttext \startTEXpage[offset=1em, width=4em] \hsize\zeropoint\tt \hyphenatedword{legibility-legible} \stopTEXpage \stoptext In current latest (and in many versions before), I get an extra hyphen in the next line after the hyphen, such as: ity- -leg As far as I can remember, I would say this used to work before (no extra hyphen was added in the next line. What am I missing here? Many thanks for your help, Pablo

two issues with variable fonts
by Pablo Rodriguez 09 Dec '22

09 Dec '22

Hi Hans, I have two issues with variable fonts (using current latest from yesterday): 1. Using the following sample: \usemodule[fonts-variable] \starttext \showfontvariations[font=file:grenze.ttf] \stoptext With the fonts from https://github.com/Omnibus-Type/Grenze/tree/master/fonts-/gx, I get the following error message: lua error: run callback [6]: ...ext/tex/texmf-context/tex/context/base/mkxl/lpdf-emb.lmt:84: number (local 'n') has no integer representation stack traceback: ...base/mkxl/lpdf-emb.lmt:84: in upvalue 'tocardinal2' ...base/mkxl/lpdf-emb.lmt:771: in local 'writer' ...base/mkxl/lpdf-emb.lmt:2358: in field 'integer index' ...base/mkxl/lpdf-ini.lmt:828: in upvalue 'run' ...base/mkxl/lpdf-ini.lmt:859: in field 'finalizedocument' ...base/mkxl/lpdf-lmt.lmt:3413: in field '?' ...base/mkxl/luat-run.lmt:58: in function <...ext/tex/texmf-context/tex/context/base/mkxl/luat-run.lmt:56> <empty file> mtx-context | fatal error: return code: 1 This crashes LuaMetaTeX but not LuaTeX. 2. The other font is Recursive (https://github.com/arrowtype/recursive/tree/main/fonts/recursive_for_google…) \usemodule[fonts-variable] \starttext \showfontvariations[font=file:recursive.ttf] \stoptext There are some some instances (in pages 4 to 14) that don’t have the font (only Latin Modern Roman). Also in the last instances (at least, pages 19 to 25), kerning or interletter spacing clearly needs to be improved. Many thanks for your help, Pablo

\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.

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]

Convertnumber with \ref[number] fails in MkIV, works in LMTX
by Rik Kabel 06 Dec '22

06 Dec '22

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: ! Incompatible glue units , pointing to the second \convertnumber line. \definelabel[XX]%[text=,before=,after=,alternative=inright] \startTEXpage[offset=2em] abc\XX[xx]\par \ref[number][xx] · \convertnumber{r}{1} · \convertnumber{R}{\ref[number][xx]} \stopTEXpage In this case I am trying to display with roman numerals the number generated in the label created through \definelabel. Suggestions welcomed. -- Rik
