update and meeting
by Hans Hagen 15 Sep '20

15 Sep '20

Hi, I uploaded a new version. It is a follow up on the ctx meeting of last week (in a country side compound in czech with also some remote attendants, daily infrared health scans, an excursion, talks, breaks, food, and the usual have fun with context friends moments). There are a few changes that can affect users numbered 1 and 2 below. (1) During one of the coffebreak discussions we agreed to drop the two units that were never official and are kind of meaningless: 'nc' (new cicero) and 'nd' (new didot). Arthur made some stroing arguments and only Tomas remembered ever entering one of them so there was no resistance. We also considered that in order to enforce the use of si units the 'in' should go away but that has been postponed (it is anyway last in the checked keywords so has no overhead). At some point the "true" prefix might go too (never really used, but no overhead either). (2) Another change is in the \startdocument mechanism. This (already old and rusted) wrapper runs on top of variables but we think no one knows (or uses) that. So, it now is a real wrapper with inheritance and such. It is dedicated to Tomas Hala who had to struggle with the old one but still gave a presentation using it. Here's an example: \definedocument[thesis] \setupdocument[a=b,e=f] \setupdocument[thesis][a=x,c=d] % \startsetups[thesis:start] \startsetups[document:start] START \stopsetups \startsetups[thesis:stop] % \startsetups[document:stop] STOP \stopsetups % \startdocument[thesis] \startthesis (\currentdocument/a): \documentvariable{a}\par (\currentdocument/c): \documentvariable{c}\par (\currentdocument/e): \documentvariable{e}\par \stopthesis % \stopdocument There's also a user mode set with the document enviroments name. (3) Some other additions are for Taco so will not be disclosed here (yet). (4) There are some summaries of my presentations added to the distribution (the wiki will collect more at some point). 1 context-2020-mkii-mkiv-mkxl.pdf 2 context-2020-luametatex.pdf 3 context-2020-concepts.pdf 4 context-2020-tokens.pdf 5 context-2020-implementers.pdf 6 context-2020-datatypes.pdf 7 context-2020-ecmascript.pdf 8 context-2020-svg.pdf 9 context-2020-mp.pdf They use the new 'boring' presentation style and most are probably useless without demos and discussion but anyway ... The first one is an overview of the three successive context versions. The second one is about the state of luametatex and the third discusses a couple of things introduced last year (luametatex and lmtx). The tokens talk is for low level tex lovers (or those who need to impress other texies with token speak), and the talk about implementers was probably only useful for wolfgang and me, but who knows. The datatypes are an overview over what is standard in tex and in lua as well as what we have extra on top of that. The seventh talk fits in the 'we also need to have some fun talks', and the eigths one was for a large part a discussion and accompanied by a demo by Hraban. The last one is (of course) also a fun one and (of course) discusses Don Knuths latest font which (of course) is kind of special Anyway, it's all part of the 'we keep going' story, which is why they are in the distribution. (5) We had several talks / discussions about the greatly improved wiki and users are invited to participate in completing the pages that need to be filled in, but I leave that to Taco to summarize.

footnotes in captions in floatcombinations
by Henning Hraban Ramm 14 Sep '20

14 Sep '20

Hi, I got a problem with current LMTX as well as with other versions – while I’m sure it used to work at some point: As soon as there’s a footnote in the caption of a placefigure within a floatcombination, the figure won’t get placed. There’s no problem outside of floatcombinations or with floatcombinations without footnotes. Please let there be an easy fix... Hraban \useMPlibrary[dum] \automigrateinserts \showframe \starttext \input knuth %\startplacefigure[location=none] %\startfloatcombination[2*1] \startplacefigure[title={Image with footnote\footnote[f:1]{foo bar baz}}] \externalfigure[001][width=.48\textwidth] \stopplacefigure \startplacefigure[title={Another image with footnote\footnote[f:2]{Something}}] \externalfigure[002][width=.48\textwidth] \stopplacefigure %\stopfloatcombination %\stopplacefigure \input lorem \startplacefigure[location=none] \startfloatcombination[2*1] \startplacefigure[title={Left Image\footnote[f:3]{doo be doo}}] \externalfigure[003][width=.48\textwidth] \stopplacefigure \startplacefigure[title={Right Image%\footnote[f:4]{Anything} }] \externalfigure[004][width=.48\textwidth] \stopplacefigure \stopfloatcombination \stopplacefigure \startplacefigure[location=none] \startfloatcombination[2*1] \startplacefigure[title={Left Image}] \externalfigure[005][width=.48\textwidth] \stopplacefigure \startplacefigure[title={Right Image}] \externalfigure[006][width=.48\textwidth] \stopplacefigure \stopfloatcombination \stopplacefigure \input tufte \stoptext

Force bottom float to be at the bottom
by Mikael Sundqvist 13 Sep '20

13 Sep '20

Hi, I'm defining a bottomfigure with default=bottom, but it does not always seem to work (example below). If the float does not fit on the page, it appears instead in the top of the next page. Can I force it to be in the bottom of the next page? That is, can I setup a float that is always at the bottom of the page? I hope what I ask makes sense. /Mikael \useMPlibrary[dum] \definefloat[bottomfigure][bottomfigures][figure] \setupfloat[bottomfigure][default=bottom] \starttext \dorecurse{4}{\samplefile{knuth}} \startplacebottomfigure \externalfigure[dummy][width=\textwidth] \stopplacebottomfigure \samplefile{knuth} \stoptext

How do I specify a fallback to Symbola for the playing card range?
by T. Kurt Bond 11 Sep '20

11 Sep '20

I want to use the Unicode Character PLAYING CARD ACE OF SPADES in a ConTeXt document. Because of the way the source document is created it has to be as the actual unicode character itself, rather than a reference to a specific character in a specific font. Here's what I've tried, but it doesn't work: \definefontfallback[mainface][rm][Symbola][preset=range:playingcards,force=yes] \definefontfamily[mainface][rm][LibertinusSerif] \enabletrackers[fonts.missing] \setupbodyfont[mainface] \starttext 🂡 Testing! \stoptext The PLAYING CARD ACE OF SPADES character does not show up in the output PDF. Can anyone tell me how to do this? Thanks! -- T. Kurt Bond, tkurtbond(a)gmail.com, https://tkurtbond.github.io

Access violation
by Christoph Reller 10 Sep '20

10 Sep '20

Dear developers, I am using ConTeXt LMTX version 2020.09.05 21:18 on Windows 46bit. I have a large project for which I can reproduce an access violation: mtx-context | fatal error: return code: -1073741819 Unfortunately, the error vanishes as soon as I alter any detail in the project's source code. The access violation happens always at the same location. I have produced a log file for which I have enabled \tracingall just before the error happens. I suspect that the error is triggered due to tagging information written to the PDF (\setuptagging[state=start]), because disabling tagging prevents the error. The log file (as a ZIP archive) is here <https://drive.google.com/file/d/1xv5ZxQi4IfyS50HD60z-Nk-FOW_-afU-/view?usp=…>. Does this help or do you really need a MWE? Kind regards Christoph

\definefontfamily not finding fonts
by Aditya Mahajan 10 Sep '20

10 Sep '20

Did something change with regard to \definefontfamily recently. I have an old document where I use: \starttypescript[mainface] \definefontfamily[mainface][rm][Libertinus Serif][features=default] \definefontfamily[mainface][ss] [heros] [features=default] \definefontfamily[mainface][tt] [dejavu] [features=none, rscale=0.85] \definefontfamily[mainface][mm] [LibertinusMath] \stoptypescript \setupbodyfont[mainface,12pt] On the recent LMTX (2020.09.05) I get selectfont > the requested font 'Libertinus Serif' has no files for the 'tf' alternative, Latin Modern is used instead. selectfont > the requested font 'heros' has no files for the 'tf' alternative, Latin Modern is used instead. selectfont > the requested font 'dejavu' has no files for the 'tf' alternative, Latin Modern is used instead. selectfont > the requested font 'LibertinusMath' has no files for the 'tf' alternative, Latin Modern is used instead. I can find the fonts using mtxrun --script fonts. For example: $mtxrun --script fonts --list --pattern="LibertinusSerif" --all identifier familyname fontname filename subfont instances libertinusserif libertinusserif libertinusserif libertinusserif-regular.otf libertinusserifdisplaynormal libertinusserifdisplay libertinusserifdisplay libertinusserifdisplay-regular.otf libertinusserifdisplayregular libertinusserifdisplay libertinusserifdisplay libertinusserifdisplay-regular.otf libertinusserifinitialsnormal libertinusserifinitials libertinusserifinitials libertinusserifinitials-regular.otf libertinusserifinitialsregular libertinusserifinitials libertinusserifinitials libertinusserifinitials-regular.otf libertinusserifnormal libertinusserif libertinusserifitalic libertinusserif-italic.otf libertinusserifregular libertinusserif libertinusserif libertinusserif-regular.otf and similar for the other fonts. Any idea on what is going on and how to debug. Thanks, Aditya

problem embedding TABLE macros within wrapper macros "to reduce repetitive complexity")
by Rudd, Kevin 10 Sep '20

10 Sep '20

I have a number of slides using \...framedtext blocks to break the slides into panes within a TABLE environment (TMI: not in MWE; merely my justification for writing the wrapper macros). When the TABLE macros are invoked explicitly it all works fine and produces a suitable single-cell table with "quux blech baz bar foo" framed; when embedded in macros (whether defined by \def, \unexpanded\def, \define) then it fails with the error "The file ended when scanning an argument. => fatal error: return code: 256. A previous question on the topic seemed to indicate that TABLE was suitable, so I figure that something subtle is wrong as I've invoked the embedded TABLE macros. Any suggestions? Many thanks, ---K MWE: this code fails if the \...PaneSlide block is uncommented, succeeds if commented out. \define\startPaneSlide{\bTABLE} \define\startPaneRow{bTR\bTD} \define\stopPaneRow{\eTD\eTR} \define\stopPaneSlide{\eTABLE} \starttext \bTABLE \bTR\bTD quux blech baz bar foo \eTD\eTR \eTABLE \startPaneSlide \startPaneRow foo bar baz blech quux \stopPaneRow \stopPaneSlide \stoptext Kevin W.

Hi, The certificate for *.contextgarden.net expired this morning. I installed a new certificate just now, but it is possible that I missed one of the uses of the old certificate. If you find that you get an error about ‘Connection is not private’ still, even after a hard reload, please send me message as I likely forgot to update some file. Best wishes, Taco
