update
by Hans Hagen 28 Apr '23

28 Apr '23

Hi, I uploaded a new version with some new features discussed at the end of this mail. - A next version of luatex will break context (format making etc) but the change is unavoidable because of other macro package demands wrt security (context does that differently). The low level start up command has been adapted so unless you update indepdently thinsg should work ok. Of course this has no consequences for lmtx. - I've done a bit of callback cleanup (like getting rid of some mkiv luatex left-overs). It should have no effect on regular usage. - There again a few improvements wrt math (this time dealing with accents artifacts in some fonts). We check all the free math fonts for potential issues and then try to fix it (read: deal with it). It's a lot of work but we're getting there. - A few reported buglets have been fixed. - The biggest addition is however a new number model. In metapost one can now use 'posit' (positfun instance) as number mode which will use (currently 32 bit but at some point 64 bit) posit unums. It's also bit of a playground because 32 bit posits are not more accurate than 64 bit doubles. It anyhow exposed some potential issues that we'll look into. - There's also a (again currently 32 bit) posit library at the Lua end as playground. - However, 32 bit posits come in handy at the tex end because they pack better accuracy in 32 bits than floats and it makes it possible to have native floats, so we have: \newfloat (uses \floatdef, register like \dimendef is used in \newdimen) \newposit (uses \positdef, like \dimensiondef etc) \floatexpr (like \numexpr) \iffloat (like \ifnum) (also \ifabsfloat and i'll add the others too) Actually it adds an extra range of registers so it bumps memory usage a bit. I'm considering lowering the number of registers (currently 64K per category) because after all, if 64K is not enough then we can as well stick to 32K or 16K (for some even less). There's always Lua for unlimited storage of quantities. So, \newfloat\fooA \scratchdimen=123.456pt\relax [\type{dim:} \the\scratchdimen==123.456pt]\par \fooA =123.456\relax [\type{pos:} \the\fooA ==123.456] \par \fooA =\scratchdimen\relax [\type{pos:} \the\fooA ==123.456] \par \scratchdimen=\fooA\relax [\type{dim:} \the\scratchdimen==123.456pt]\par \scratchdimen\dimexpr\fooA+10pt\relax[\type{dim:} \the\scratchdimen==133.456pt]\par produces [dim: 123.456pt==123.456pt] [pos: 123.45600128173828==123.456] [pos: 123.45599365234375==123.456] [dim: 123.456pt==123.456pt] [dim: 133.456pt==133.456pt] As you can see dimens will get mapped onto floats not as integers (scaled points) but in pt units. Counts stay numbers. I need to handle glue too (not yet done). In the future I might use this for fractions but there might be some rough ends so for now it's experimental.

Hi, I uploaded the last of series 2.10.07 as prelude for bachotex. That one also can do this: \newfloat \MyFloat \MyFloat \pfsin \floatexpr 1.25 * \pfpi \relax \the\MyFloat \the \pfsin \floatexpr 1.25 * \pfpi \relax The syntax is like \numexpr and \dimexpr but the \pfsin (and other functions) are (as usual with these things) not real primitives but (\untraced) luacalls. Of course it is all still somewhat experimental but likely to stay ...

Font error in PDF using ConTeXt and Kepler typeface
by Werner Schmidt 26 Apr '23

26 Apr '23

Hi all, I'd like to use the commercial Adobe Kepler typeface (Kepler Std - version 2.020) in conTeXt (v2023-04-15) as text (serif) font. Although the font files are loaded correctly (see log below), the generated PDF is unreadable (see attached image). Notes: - Only serif font (keplerstd-light.otf) is not working. It's not embedded in the generated PDF. - italics and bold fonts are embedded and are rendered well - Can't provide font files because Kepler is a commercial typeface Do you have any ideas how to debug this issue? Thanks Werner log file: mkiv lua stats > loaded fonts: 10 files: fontawesome6freesolid900.otf, frutigernextpro-bold.otf, frutigernextpro-regular.otf, iosevka-term-ss09-light.ttf, keplerstd-light.otf, keplerstd-lightcapt.otf, keplerstd-lightit.otf, keplerstd-semibold.otf, latinmodern-math.otf, lmroman10-regular.otf mkiv lua stats > font engine: otf 3.133, afm 1.513, tfm 1.000, 30 instances, 18 shared in backend, 3 common vectors, 15 common hashes, load time 0.449 seconds Example: This text can't be read in PDF.par {it However, italics are working.}par {bold Also Bold and bfem BoldItalics!}par input{zapf}

Filter Module with Openscad
by Jeroen 26 Apr '23

26 Apr '23

I am using OpenSCAD to create drawings with the filter module with the following MWE: \usemodule[filter] \defineexternalfilter[openscad] [filtercommand={/context/openscad/openscad -o \externalfilteroutputfile}, output={\externalfilterbasefile.png}, cache=force, readcommand=\ReadImage] \define[1]\ReadImage{\externalfigure[#1]} \starttext \startopenscad square(4,2); \stopopenscad \stoptext This works fine. I now want to use the following options added to the command line: --view axes,edges,scales --viewall When I create an Openscad file test.scad, I can run it fine with the following command line at a CLI window: openscad.com test.scad -o test.png --view axes,edges,scales --viewall When I add this to the filtercommand as following [filtercommand={/context/openscad/openscad -o \externalfilteroutputfile --view axes,edges,scales --viewall} I cannot get it to run. Is there anything I am missing? Thanks Jeroen

Numbered Itemlist With Interruption
by Michael Urban 26 Apr '23

26 Apr '23

I am trying to have two numbered itemizations, with a paragraph in between, such that the second list starts where the first left off, without having to manually calculate the new start point. The following does not work, and I do not understand why. Mike \starttext \definecounter[mynumber][] \startitemize[n] \item The first item. \item The second item \item Item number \currentitemnumber{}, the last one. \setcounter[mynumber][\currentitemnumber] \stopitemize The \type{\getnumber[mynumber]} value is \getnumber[mynumber]. \incrementcounter[mynumber] And now the big finish, start at \getnumber[mynumber]: \startitemize[n][start=\getnumber[mynumber]] % WHY DOES THIS FAIL? \item Picking up where we left off. \item And all is well. \stopitemize Done! \stoptext

Idea for a shared repository.
by Pawel Urbanski 25 Apr '23

25 Apr '23

Dear Everyone, We currently have the Context Garden site, wiki and htis list for documentation and resources. There is a Github contextgarden organization that can host repositories. What about creating a repository called: 'templates' or 'resources' - we can figure out the exact name later. The idea behind it is to collect templates and examples that are scattered all over the web or in the list threads. The first example that comes to my mind is the type definition for a Roboto font I needed and other type scripts that can be useful for the community. Then there are templates for books, slides or documents. The Repository has a wiki where we could add some notes about more complex items. It is not about duplicating the Context garden site but to collect code in a place where we could gradually fix possible errors or introduce improvements. All the best, Pawel

fallbacks
by Thomas A. Schmitz 25 Apr '23

25 Apr '23

Hi all, today, I was struggling with a fallback font I had defined, and I discovered that the key "check" doesn't work as I expected. Here's a small example: \definefallbackfamily [presentation] [serif] [TeXGyreTermes] [range=0x2329-0x232A,check=yes] \definefontfamily [presentation] [serif] [AntykwaTorunska] \setupbodyfont [presentation,12pt] \starttext (〈P〉) \stoptext With this input, the two characters 〈 and 〉 are not typeset; in the log, I find fonts > checking > char 〈 (U+02329) in font 'AntykwaTorunska-Regular' with id 1: missing fonts > checking > char 〉 (U+0232A) in font 'AntykwaTorunska-Regular' with id 1: missing If I have "check=no," the characters are taken from termes and replaced. I was under the impression that "check" should, well, check if the characters are not in the main font and fall back to the fallback font if they are not, but this doesn't appear to be the case. So what does "check" do? Or is this a bug? Have a great weekend Thomas

adjustment to my local footnotes problem
by jbf 24 Apr '23

24 Apr '23

I realise that I should have been talking about the space between local footnotes, rather than interlinespace (previous email on this issue), but my basic problem still stands. My efforts to influence the space between footnotes placed locally is to no avail so far. I assume it is \setupnote (rather than \setupnotation, my earlier mistake) where I would need to somehow influence distance between footnotes which is currently too large. I have tried \setupnote[before={\blank[small]}, after={\blank[small]}]. It appears to be reducing the space before the entire block of local footnotes but not between the footnotes themselves, which is what I am trying to do. Am I correct in assuming that the \setupnote should influence my \placelocalfootnotes? Or is there something else I should do in the case of local footnotes as distinct from general footnotes (my document contains ONLY local footnotes, however). It seems a simple enough issue, but I just can't get it right. Julian

current Unicode blocks

This is probably for Hans: The list of Unicode blocks in char-ini.lua is not complete, compared with ftp://www.unicode.org/Public/UNIDATA/Blocks.txt (I was looking for Kaktovik numerals, of course ;)) I’d offer to make an updated list, but maybe you already have a script for that? Hraban

interlines space for local footnotes
by jbf 23 Apr '23

23 Apr '23

I am using only local footnotes in a document, but am having difficulty influencing the interlines space between these notes. Since I am only using local footnotes, I thought initially that the following would work for them \startsetups[footnote:interlinespace] \setupinterlinespace[line=2.4ex] \stopsetups \setupnote[footnote][setups=footnote:interlinespace] but it doesn't. I had hoped there might be something like \setuplocalfootnotes but there is not. I also tried placing the setups locally, either with \startlocalfootnotes[setups=footnote:interlinespace] or \placelocalfootnotes[setups=footnote:interlinespace]. Any idea how I can successfully influence my local footnotes globally? Julian

missing xml call
by Hans van der Meer 21 Apr '23

21 Apr '23

\xmlatt{}{} has a counterpart \xmlattribute{}{LPATH}{} where one can start the search for the attribute at LPATH. for \xmlchainatt{}{} I am missing such a counterpart \xmlchainattribute{}{LPATH}{} where one can do the same. The problem now is that \xmlchainatt{#1}{att} always finds attribute att when it is defined on the node itself. But consider the case where att="true" exists with the intention to trigger a search higher up in the call chain for that same attribute att. Of course \xmlattribute{#1}{..}{att} is not exactly the same as \xmlchainattribute{#1}{..}{att} would be . yours sincerely dr. Hans van der Meer

Non-standard font alternatives
by Matthew McCabe 20 Apr '23

20 Apr '23

Hi list, I'm looking to import a font with medium and light weights (in this case Roboto) and define font alternatives so one can quickly switch to light text just as one would switch to bold text. There is a stackexchange answer from Wolfgang (https://tex.stackexchange.com/questions/303648/context-font-weights) which details a solution to this problem for ConTeXt MkIV but despite my best efforts I haven't been able to get things to work for me. There is the Roboto typescript example on ConTeXt garden but it isn't exactly what I'm looking for as for the document I'm making I would prefer to be able to treat the font weights as alternatives rather than separate families since I will be switching often. One can download the exact set of fonts I am using from https://fonts.google.com/specimen/Roboto Here is my code: \definefontalternative[lf] % light \definefontalternative[li] % lightitalic \definefontalternative[md] % medium \definefontalternative[mi] % mediumitalic \starttypescript [sans] [roboto] \definefontsynonym [SansLight] [file:Roboto-Light] [features=default] \definefontsynonym [SansLightItalic] [file:Roboto-LightItalic] [features=default] \definefontsynonym [Sans] [file:Roboto-Regular] [features=default] \definefontsynonym [SansItalic] [file:Roboto-Italic] [features=default] \definefontsynonym [SansMedium] [file:Roboto-Medium] [features=default] \definefontsynonym [SansMediumItalic] [file:Roboto-MediumItalic] [features=default] \definefontsynonym [SansBold] [file:Roboto-Bold] [features=default] \definefontsynonym [SansBoldItalic] [file:Roboto-BoldItalic] [features=default] \definefontsynonym [SansCaps] [file:Roboto-Sans] [features=smallcaps] \stoptypescript \starttypescript [sans] [roboto] \definebodyfont [default] [rm] [lf=SansLight sa 1, li=SansLightItalic sa 1, tf=Sans sa 1, it=SansItalic sa 1, md=SansMedium sa 1, mi=SansMediumItalic sa 1, bf=SansBold sa 1, bi=SansBoldItalic sa 1, sc=SansCaps sa 1] \stoptypescript \definetypeface[roboto][rm][sans][roboto][default] \setupbodyfont[roboto] \starttext \lf Light \li LightItalic \tf Regular \it Italic \md Medium \mi MediumItalic \bf Bold \bi BoldItalic \sc SmallCaps \stoptext - The result is entirely in the regular weight default font: What I've tried: 1. I've tried a great deal of alternative \definefontsynonym arguments such as specifying by name, including the full path to each ttf file 2. I played around with different two character \definefontalternative arguments to ensure there was no overlap with existing commands (as far as I am aware the existing set are otherwise undefined) A few things to note: 1. My current version of ConTeXt is 2022.12.09 16:34 2. For portability I have included the ttf files for Roboto in a directory within my project directory and while setting things up I set OSFONTDIR to include this directory and run `mtxrun --script fonts --reload --force` 3. `mtxrun --script fonts --list --all --pattern=Robo` yields: identifier familyname fontname filename subfont instances roboto roboto robotoregular ./fonts/Roboto/Roboto-Regular.ttf robotoblack roboto robotoblack ./fonts/Roboto/Roboto-Black.ttf robotoblackitalic roboto robotoblackitalic ./fonts/Roboto/Roboto-BlackItalic.ttf robotobold roboto robotobold ./fonts/Roboto/Roboto-Bold.ttf robotobolditalic roboto robotobolditalic ./fonts/Roboto/Roboto-BoldItalic.ttf robotoitalic roboto robotoitalic ./fonts/Roboto/Roboto-Italic.ttf robotolight roboto robotolight ./fonts/Roboto/Roboto-Light.ttf robotolightitalic roboto robotolightitalic ./fonts/Roboto/Roboto-LightItalic.ttf robotomedium roboto robotomedium ./fonts/Roboto/Roboto-Medium.ttf robotomediumitalic roboto robotomediumitalic ./fonts/Roboto/Roboto-MediumItalic.ttf robotonormal roboto robotoregular ./fonts/Roboto/Roboto-Regular.ttf robotoregular roboto robotoregular ./fonts/Roboto/Roboto-Regular.ttf robotothin roboto robotothin ./fonts/Roboto/Roboto-Thin.ttf robotothinitalic roboto robotothinitalic ./fonts/Roboto/Roboto-ThinItalic.ttf 4. Using `\definedfont[name:robotomedium*default] hello` and `\definedfont[file:Roboto-Thin*default] hello` (for example) work exactly as expected I hope this isn't a silly question, I'm very new to ConTeXt and have been struggling for a while so thought I may as well ask in case there's something I'm missing, would appreciate any guidance :) Regards, Matt

Google's Roboto Flex font typescript and goodies definition.
by Pawel Urbanski 19 Apr '23

19 Apr '23

Dear Everyone, Following my attempts to create and learn Context's ways to manage fonts, I would like to ask about the following: I've created the structure for fonts in texmf-local folder and after running scripts they are listed. The output for Roboto Flex is as follows: identifier familyname fontname filename subfont instances robotoflex robotoflex robotoflexregular robotoflex.ttf thin extralight light regular medium semibold bold extrabold black extrablack thinitalic extralightitalic lightitalic italic mediumitalic semibolditalic bolditalic extrabolditalic blackitalic extrablackitalic What is the proper way to use family name or font name to create a typescript file and a goodies file to take advantage of optical sizes. Google's Roboto Flex is an upgraded Roboto as a variable font. I know that this topic has been discussed many times and I've read the fonts manual but still have these questions. Most of the examples are rather ready solutions or templates but not always cover ways how to figure out values from scratch and how they correspond. Thanks for help, Pawel

regular online meet-up
by Henning Hraban Ramm 19 Apr '23

19 Apr '23

You’re invited to join on Wednesday, April 12th, 15:00 CEST (UTC+2) at https://lecture.senfcall.de/hen-rbr-rku-oke (same, but shorter: https://v34h.de/ctxmtg) ConTeXt users of all levels are welcome! Next meeting will be on May 10th. (Same blurb as every time:) [Howto] * No special software installation required; most modern browsers should work (WebRTC required). * Open the above URL, accept the privacy statement, * enter your name, * click "join" (or "start" if you’re the first), * click "with microphone", allow your browser to access it, check the audio. * Your microphone is muted if you join. Activate microphone and/or camera with the buttons at the bottom. * Minimize the default presentation with the "screen" button, bottom right. * If you’d like to share your screen or upload a file, you can make yourself the presenter: Click on your user name, change the setting, then you’ll see the "screen sharing" button beside the camera button; also there’s now "manage presentations" behind the "plus" button. Beware there is only one presenter at a time, so don’t kill someone else’s presentation. [Technical hints] * Sound is usually better if you use a headset (less noise for everyone). * Connection problems are mostly due to low bandwidth or high latency on your side, e.g. with mobile connections. * If audio/video doesn’t work for you, you can still use the text chat. * Screen sharing needs a lot of bandwidth. * BigBlueButton documentation applies: https://bigbluebutton.org/teachers/tutorials/ [Netiquette] * Please use a name that we recognize from here. Some feel uncomfortable with anonymous lurkers. * Mute your microphone while you’re not talking. * It’s nice to show your face at least when you join. * If there are connection problems, stop camera sharing. * The room is set to “everyone’s a moderator“, I trust you... See you, Hraban

\setupitemize[indentnext=auto] broken?
by Jim 19 Apr '23

19 Apr '23

In the wiki page https://wiki.contextgarden.net/Indentation there is the following example: %------------------------------------------------------------------------ \setupindenting[medium,yes] \setupitemize[indentnext=auto] \startitemize \item One \stopitemize This paragraph should be indented - due to the blank line after \type{\stopitemize}. \startitemize \item Two \stopitemize This paragraph should not be indented. %------------------------------------------------------------------------ Tragically, the paragraph which claims it should be indented is not, in both my test and the wiki page itself. Is this a documentation bug, a ConTeXt bug, or something else yet? Cheers. Jim

Table of contents in the middle of a document

Hi, I was trying to have my "Acknowledgements" section/chapter before the table of contents but be contained within it. Is it normal that the table of contents is empty if there is a chapter that begins before it? ``` \starttext \chapter{Acknowledgements} Thank you \completecontent \chapter{Intro} \chapter{Problem} \chapter{Solution} \stoptext ``` I'm mostly looking for an explanation rather than a direct solution, I'd like to understand why it's empty. It works when using sections instead of chapters. Best regards, -- Kalouguine Andre

There are no high level definitions yet as we have to invent names but this is how it works (private unicode slots might change): \setupbodyfont[pagella] \starttext \setupmathdelimited [topoffset=.2\exheight] \definemathdelimited [fourier] [rule=no, left=\zerocount, right="FE944] \definemathdelimited [courier] [rule=no, left=\zerocount, right="FE946] \definemathdelimited [xourier] [rule=no, left=\zerocount, right="FE948] $ \fourier{(z+1)} $ $ \fourier{(z+1)} + \sqrt[2]{1}$ $ \fourier{(z+1)} + \courier{(z+1)} + \xourier{(z+1)} $ $ \fourier{\left(z+\frac12\right)} + \courier{\left(z+\frac12\right)} + \xourier{\left(z+\frac12\right)} $ $ \autofences \fourier{(z+\frac12)} + \courier{(z+\frac12)} + \xourier{(z+\frac12)} $ $ \widehat{x^2 + 2x + 2} $ \stoptext This example also shows a new \autofences feature and widehats (widetilde and widecheck also work that way) that overcome limitations in fonts, so \def\CrappyHack#1{\im{#1{a} + #1{a+b} + #1{a+b+c} + #1{a+b+c+d} + #1{a+b+c+d+e} + #1{a+b+c+d+e+f}}\par} \CrappyHack\widehat \CrappyHack\widetilde \CrappyHack\wideacute \CrappyHack\widecheck will work. For thise in finance we now have $ \annuity{x + 1} + \lannuity{x + 1} + \rannuity{x + 1} + \lrannuity{x + 1} $ these are basically radicals (like sqrt) with two sided symbols.

help wanted: English native speaker as co-editor
by Henning Hraban Ramm 16 Apr '23

Hi, as most of you know, I’m the editor of context journal, the annual magazine for all members of context group, AKA “proceedings of the [previous] ConTeXt meeting”. While I have some experience as an editor in German, my English is far from perfect, so I need to rely on a native speaker for proofreading. In the least years, Clyde was filling that role very diligently, but he just moved and can’t make the time again. Deadline for the current issue is only in August, but we’re already at ~100 pages with the articles I got (by Willi, Willi, Willi, Taco, Taco, Götz, and me) and I’d like to spread the work a bit. * Would you like to help with that? * – You don’t need to understand the code. – I want the text to be correct and understandable, we don’t need to reach literary quality. – You can work in PDF or in the sources, as you like. – More than one person is welcome. BTW I never thought of offering “our” articles to TUG and NTG, while I sometimes got articles that were published in TUGboat or MAPS first. (And I’m writing/translating for DANTE’s DTK regularly.) I’ll start to do that, since “recycling” makes sense, and it also can’t hurt to spread the word. This is also a reminder to hand in your talks from Dreifelden – or new articles! Hraban
