what happend to \writeline?
by Werner Hennrich 31 May '21

31 May '21

Hello everyone, I'm looking into my environment's logging to trace a problem and realize that \writeline is gone mute - that is, the output of subsequent logging lines now gets joined up in the same line, very hard to read... I observe this in version: 2021.05.27 14:15, as well as in version: 2021.05.27 14:15 the last one I used where \writeline did write (and end) the logging line was version: 2021.03.17 17:46. \def\log#1{ \message{ logging: #1} \writeline logging #1\par } \starttext \log{the} \log{quick} \log{brown} \log{fox} \stoptext used to log like this: logging: the logging: quick logging: brown logging: fox but now: logging: the logging: quick logging: brown logging: fox Any idea how I can switch back the old behavior (on the new lmtx)? Thanks you, Werner

new page before xtable with repeated headers
by Werner Hennrich 31 May '21

31 May '21

Hello everyone, I'm having an xtable spanning several pages and need to have its headers repeated. For this I've set "split=repeat", but unfortunately this causes the table to start with a new new page leaving the rest of the preceding page empty. Having "split=yes" makes the tabe continue on the previous page as a need it to, but then the header isn't repeated any longer. I realize that there has been a very similar question already in https://www.mail-archive.com/ntg-context@ntg.nl/msg93775.html, but my problem happens isolated in a very clean situation w/o any header, floats or the like - and I don't see yet how I can get this working in my situation. Any help is highly appreciated, here is a MWE of my problem: \definextable[mytable] \setupxtable[mytable] [ option=max, split=repeat, %split=yes, header=repeat, width=\textwidth ] \definextable[mytable:header] \setupxtable[mytable:header] [ foregroundstyle=\bf, foregroundcolor=darkred, ] % ================================================== \startdocument \dorecurse{2} { \input tufte \vskip7mm } \startxtable[mytable] \startxtablehead \startxrow[mytable:header] \startxcell Some Header \stopxcell \startxcell More Header \stopxcell \stopxrow \stopxtablehead \startxtablebody \dorecurse{10} { \startxrow \startxcell {\bf (\recurselevel) some tale:} \startitemize \item a quick \item brown fox \item jumps over \item the lazy dog \stopitemize \stopxcell \startxcell {\bf and a fact:} \startitemize \item the vodka \item is good \item but the meat \item is rotten \stopitemize \stopxcell \stopxrow } \stopxtablebody \stopxtable \stopdocument Thank you very much i.a., Werner

Side-by-side environment
by Tommaso Gordini 31 May '21

31 May '21

Hello everybody. Some time ago, Wolfgang helped me write an environment to have code above and typeset output below. I'll glue you a MWE below. \mainlanguage [it] \setupbodyfont [modern] \defineuserdata [example] [alternative=example] \defineuserdataalternative [example] [renderingsetup=userdata:example] \startsetups [userdata:example] \blank \startembeddedxtable [width=\textwidth,strut=no,offset=1ex,framecolor=black,rulethickness=0.5pt] \startxrow [corner=03,align=normal] \startxcell \typebuffer [userdata] [option=tex] \stopxcell \stopxrow \startxrow [corner=01,align=normal] \startxcell \getuserdata \stopxcell \stopxrow \stopembeddedxtable \blank \stopsetups \starttext \startuserdata [example] \starttext C’era una volta un re\dots \stoptext \stopuserdata \stoptext Now, the question: Can the code to be improved? How can I modify the code to have the example typeset to the right of the box? I would like the box to be 0.5\textwidth wide. Thanks in advance Tommy

\startstaticMPfigure not producing .pdf or .mp.md5 files
by Gavin 30 May '21

30 May '21

Hello colleagues, I’m writing a physics textbook with lots of figures, some quite complex. I’ve been using TikZ, but I’m experimenting with MetaPost. Consulting the ConTeXt wiki, I found that \startstaticMPfigure and friends are designed exactly for this sort of use. However, I’m not seeing the documented behavior. In particular, I’m not seeing .pdf and .mp.md5 files being produced. Perhaps I don’t know where to look. I thought they would be in the same directory as the document. The example from the wiki is this: \startstaticMPfigure{center} draw fullcircle scaled 2cm ; dotlabel.bot(textext("(0,0)"),origin) ; \stopstaticMPfigure \startstaticMPfigure{radius} draw fullcircle scaled 2cm ; drawarrow (0,0)--(1cm,0) ; label.bot(textext("$r$"),(5mm,0)) ; \stopstaticMPfigure \starttext Circle centered \usestaticMPfigure[center][width=1cm] at origin with radius \usestaticMPfigure[radius][width=1cm] $r=1\,\text{cm}$. \stoptext I would expect this to produce files center.pdf, radius.pdf, center.mp.md5, radius.md.mp5, and perhaps other logs, etc. I don’t see them anywhere. I’m running on MacOS with a current LMTX from TeXShop with the script: #!/bin/bash export PATH=/Users/Gavin/context-osx-64/tex/texmf-osx-64/bin:$PATH ~/context-osx-64/tex/texmf-osx-64/bin/mtxrun --autogenerate --script context --directives="system.showerror" --autopdf "$1” I’ve also tried MkIV and the TeXLive 2021 versions with the same results. I don’t actually need the separate pdf, but I do want the diagrams to be redrawn only when something has changed. Without a .mp.md5, I’m not sure what to expect. If the behavior has changed, I can update the wiki. I’m also curious about why \staticMPfigure is not mentioned in the MetaFun manual. Thanks Gavin

chapter number sought
by Hans van der Meer 30 May '21

30 May '21

With \pagenumber I can call up the current pagenumber and typeset it. But \chapternumber is not defined. How can I typeset the current chapternumber or even the current chapternumber.sectionnumber.subsectionnumber, for example? dr. Hans van der Meer

How to write readable source files?
by Jan U. Hasecke 30 May '21

30 May '21

Hi all, how do you format your ConTeXt source files? I recently discovered prettier which reformats source files for different markup and programming languages such as html, markdown, json etc. There are some other tools around but I don't find anything for ConTeXt. Do you know of any prettifying tool? Is there a best practice for ConTeXt source files, at all? Ciao! Jan Ulrich Hasecke

Synctex broken in LMTX ?
by Otared Kavian 29 May '21

29 May '21

Hi Hans, I have been noticing for some time that \setupsynctex does not work properly, at least in TeXShop on MacOS. A « filename.synctex » file is created but on most occasions it does not contain many lines, and one cannot go from the PDF file to the right location in the source file. Has something changed in the way synctex used to work ? Below I am sending you a test file with its PDF and .synctex files, for you to see for yourself. Sorry for the disturbance… Best regards: Otared

ctxlua percentage format escape
by Adam Reviczky 29 May '21

29 May '21

Hi, I was trying to use a quick calculation like the new mathfun in lmtx for an older mkiv document. MWE from the wiki: https://wiki.contextgarden.net/Programming_in_LuaTeX#Examples \starttext $\pi = \ctxlua{context("\%.6f", math.pi)}$ \stoptext But that gives an error (actually for both lmtx and mkiv): token call, syntax: [ctxlua]:1: invalid escape sequence near '"\%' Whereas \starttext $\pi = \startluacode context("%.6f", math.pi) \stopluacode$ \stoptext Works fine as expected. Is there a way to escape the percentage sign in ctxlua as a format value? Adam

Fwd: --luatex option failing
by jbf 29 May '21

29 May '21

Pablo, thanks for the assistance you gave me... it made me look at the cache inside the lmtx folders and I could see that the entire luatex folder was missing. I did try your --erase and --generate moves, but that did nothing to resolve things, so I installed the latest 2021.05.27 14:15 and the problem is resolved.

BibTeX inproceedings entries not rendered correctly in APA style
by Nicola 29 May '21

29 May '21

I don't know if this is restricted to inproceedings entries, but consider the following test.bib: @inproceedings{Foo:1983, author = {Foo, Bar}, booktitle = {Booktitle}, pages = {34--39}, title = {Title of the paper}, year = {1983} } When this is typeset: \usebtxdataset[test.bib] \usebtxdefinitions[apa] \starttext \cite[Foo:1983] \placelistofpublications \stoptext the result is: (Foo, 1983) Foo, B. (1983). Title of the paper. In Title of the paper., Booktitle. Author. I would expect: (Foo, 1983) Foo, B. (1983). Title of the paper. In Booktitle, p. 34–39. or something similar. I can reproduce it with ConTeXt from TeX Live 2021 and the current LMTX. Is it a bug? Nicola
