issue with custom hyphenator
by Pablo Rodriguez 10 Feb '23

10 Feb '23

Dear list, I have just copied this from https://www.pragma-ade.com/general/manuals/languages-mkiv.pdf#page=23: \startluacode local subset = { a = true, e = true, i = true, o = true, u = true, y = true, } languages.hyphenators.traditional.installmethod("test", function(dictionary,word,n) local t = { } for i=1,#word do local w = word[i] if subset[w] then t[i] = { before = "<" .. w, after = w .. ">", left = false, right = false, } else t[i] = false end end return t end ) \stopluacode \definehyphenationfeatures [demo] [alternative=test] \setuphyphenation[method=traditional] \starttext %\righthyphenmin=-1 \sethyphenationfeatures[demo] \hsize\zeropoint coming anaback \stoptext Using current latest (from 2023.02.07 19:06), I get: c<o o>ing an<a a>ack I’m missing m and b in the hyphenated words. I’m afraid that the hyphenator is all Greek to me. Is there any reason why letters are lost in hyphenation? I’m afraid (I think) I might have hit a bug. Many thanks for your help, Pablo

setupregister/placeregister
by Alan Braslau 10 Feb '23

10 Feb '23

Hello, The criterium key in setupregister (so placeregister, placeindex, ...) takes the following values: criterium local text current previous all section all: places all entries of the document section: (part, chapter, section, ...) places entries associated with that structure element. Can someone explain local, text, current, previous for their scope and perhaps subtle differences are not entirely obvious to me. Thank you Alan

Chapter title in MetaFun manual.
by Jeong Dal 10 Feb '23

10 Feb '23

Dear all, I copied the code of defining chapter command from metafun-000.tex, and run it. But the result is different from that in MetaFun Manual. There is a big spaces between the number and the title which yields the number cannot be seen. I commented out several lines which seems to be not-related with chapter title. And, I changed \def\ChapterCommand#1#2% —> \define[2]\ChapterCommand Would you please test the following code to find out what is wrong? Thank you for reading. Best regards, Dalyoung \startuseMPgraphic{circled} pickup pencircle scaled 1mm ; drawoptions(withcolor (.6+uniformdeviate.35)*white) ; fill fullcircle xscaled 1.5cm yscaled 1cm ; drawoptions(withcolor .625yellow) ; draw fullcircle xscaled 1.5cm yscaled 1cm ; \stopuseMPgraphic %\startnotmode[proof] % \defineoverlay[circled][\useMPgraphic{circled}] %\stopnotmode \define[1]\Circled% {\framed [background=circled,frame=off,offset=overlay] {\color[darkred]{#1}}} \setuppagenumbering[location=] \setupheadertexts[margin][][\hbox to \hsize{\hss\Circled\pagenumber\hss}] \startuniqueMPgraphic{titled} path p ; p := unitsquare xscaled \overlaywidth yscaled \overlayheight ; pickup pencircle scaled 1mm ; drawoptions(withcolor .625yellow) ; draw llcorner p -- lrcorner p ; setbounds currentpicture to p ; \stopuniqueMPgraphic \defineoverlay[titled][\uniqueMPgraphic{titled}] \define[2]\ChapterCommand% {\setbox0=\hbox to \leftmarginwidth{#1\hss}% \hskip-\leftmarginwidth \hskip-\leftmargindistance \framed [background=titled,frame=off,offset=0pt] {\box0 \hskip\leftmargindistance #2}} \define[2]\TitleCommand% {\framed [background=titled,frame=off,offset=0pt] {#2}} \setuphead [chapter]%,section,subsection] [command=\ChapterCommand, style=\ss\bf\tfd, color=darkred] \setuphead [title]%,subject,sububject] [command=\TitleCommand, style=\ss\bf\tfd, color=darkred] \setupbodyfont[bonum,rm,12pt] \showframe \starttext \startchapter[title={Introduction}] This is the chapter for introduction. \stopchapter \startchapter[title={Function}] Now, we study the function. \stopchapter \starttitle[title={References}] \startitemize[n] \item first \item second \item third \stopitemize \stoptitle \stoptext

regular online meet-up
by Henning Hraban Ramm 08 Feb '23

08 Feb '23

You’re invited to join on Wednesday, February 8th, 15:00 CET (UTC+1) 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 March 8th. (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

Iwona error
by Bruce Horrocks 06 Feb '23

06 Feb '23

Just installed today's update (ConTeXt ver: 2023.02.06 17:58 LMTX) and tried out the 3 fonts mentioned. \setupbodyfont[iwona] % \setupbodyfont[kurier] % \setupbodyfont[antykwa] \starttext Some text \stoptext I did a ./install.sh update with no obvious errors and afterwards Kurier and Antykwa worked for me on the above MWE but Iwona failed with the log entry: [snip] luatex warning > font: lua-loaded font '21' with name 'ex-iwonar' has no characters fonts > virtual math > the mapping is incomplete for 'iwonamath' at 7pt tex error > tex error on line 1 in file ./tt.tex: lua error: registered function call [1154]: ...-64/tex/texmf-context/tex/context/base/mkxl/math-vfu.lmt:677: attempt to index a nil value (local 'fci') stack traceback: ...-64/tex/texmf-context/tex/context/base/mkxl/math-vfu.lmt:677: in upvalue 'virtualize' ...-64/tex/texmf-context/tex/context/base/mkxl/math-vfu.lmt:1014: in function <...-64/tex/texmf-context/tex/context/base/mkxl/math-vfu.lmt:725> (...tail calls...) ...-64/tex/texmf-context/tex/context/base/mkxl/font-def.lmt:485: in field 'read' ...-64/tex/texmf-context/tex/context/base/mkxl/font-ctx.lmt:1377: in function <...-64/tex/texmf-context/tex/context/base/mkxl/font-ctx.lmt:1234> (...tail calls...) [snip] Not sure if that's to do with my setup or true for everyone. I've never used those fonts before if that makes a difference. — Bruce Horrocks Hampshire, UK

lmtx update
by Hans Hagen 06 Feb '23

06 Feb '23

Hi, We were considering to drop the virtual math fonts mechanism (which has served its purpose in the transition in the very early days of luatex but became obsolete as math fonts evolved) but in the end we were forced keep this feature and even upgrade it because we liked iwona, kurier and anwykwa math too much. A typical case where one needs a week for reviewing, supporting, discussing, testing a few fonts, so let's hope it wi;l be used. Iwona and Kurier are nice sansish fonts and antykwa has a rather distinctive look and feel. The current variant works okay for most of math (in most weights of the fonts) but then, these fonts are not used for complex math or math using obscure symbols anyway. It can also serve as a test case for somewhat ancient fonts but it is configured in the modern way we like more (as we might completely drop old code paths some day anyway). And so, this update is dedicated to Janusz Nowacki, a Polish font friend, who passed away some time ago. % \setupbodyfont[iwona] % \setupbodyfont[kurier] % \setupbodyfont[antykwa] Hans & Mikael ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | www.pragma-ade.nl | www.pragma-pod.nl -----------------------------------------------------------------

Fwd: BachoTeX 2023: invitation and call for papers
by Henning Hraban Ramm 05 Feb '23

05 Feb '23

-------- Weitergeleitete Nachricht -------- Betreff: BachoTeX 2023: invitation and call for papers Datum: Wed, 1 Feb 2023 20:33:11 +0100 Von: Jerzy.Ludwichowski <Jerzy.Ludwichowski(a)gust.org.pl> Dear Friends, please pass on the BachoTeX 2023 announcement to your members. With best wishes, -- Jerzy Ludwichowski =========================================== Dear TeX users and friends, good news - come what may, there will be BachoTeX 2023 as indeed I promised when announcing BachoTeX 2022 cancellation. The SARS-CoV-2 virus did not disappear but seems to have become less of a danger as far as one can tell. The war in Ukraine is raging still, but none the less we decided to organize BachoTeX 2023 at the usual dates and venue. We hope that for the fall and to make up for the lost time by keeping the same theme as the cancelled 2020 conference. Please find below the call for papers for BachoTeX 2023, with the same theme as planned for BachoTeX 2020 and 2022. The dates are from 29th of April until 3rd of May, 2023. Registrations will be announced separately as soon as possible. -- Jerzy Ludwichowski (for the Organizing Committee) The 28th GUST TeX conference A model kit. Modeling and implementing text typesetting in TeX and other systems. TeX as a program created by a scientist - Professor of The Art of Computer Programming, D. E. Knuth - stands out among other typesetting programs. Here we have not only an implementation but also a theoretical model to explain its behavior. For example the line breaking algorithm is based on the "algebra of glue and boxes". Algorithms designed for TeX became the basis for several scientific publications. TeX became a suitable environment for research in typography. We ask participants to reflect on the dependencies between theoretical models and implementation. Do they help or are they an obstacle? * Papers/presentations Of course we also look forward to the normal mix of TeX, Metafont/Metapost (please, do not forget the fonts!), ConTeXt, LaTeX, and friends related presentations. We also do upkeep the BachoTeX trend in which we try to bring together programmers and designers of typographic systems, typographers and other users of such systems. The normal channel of offering papers is the emailing of proposals to the Program Committee, but before rushing off to the mailer, please consult the info for authors. * Workshops and tutorials We look forward to proposals for TeX-related tutorials or introductions. If you have suggestions for tutorials or workshops by others than yourself or about specific topics, please let us know. * Poster sessions As always at BachoTeX participants will be given the opportunity to present their TeX and typographic results in the form of posters for which we provide exhibition space. * Deadlines and addresses The deadline for "regular" abstracts and other proposals is March 26th, 2023. The deadline for final papers to appear in the conference materials is April 16th. Contributions should be sent by email to the Program Committee: prog-2023 at gust.org.pl. The Program Committee is chaired by Bogusław Jackowski (b_jackowski at gust dot org dot pl). For other conference details see http://gust.org.pl/bachotex/2023-en.

A corner case relating to corners!
by Bruce Horrocks 05 Feb '23

05 Feb '23

In the Wiki <https://wiki.contextgarden.net/Command/setupframed> the examples for corner styles 00 - 09 no longer work and the single digit values 0 - 9 need to be used instead. (Styles 10 upwards continue to work as per the page.) Is this a deliberate change and the Wiki needs to be updated or should the change be reverted for backwards compatibility? MWE: \starttext \framed[corner=7]{Some text} \stoptext With value 07 the frame doesn't display, with value 7 the frame appears as expected. (Readers with a long-haired white cat can try corner=007) ;-) Version: ConTeXt ver: 2023.01.26 18:34 LMTX — Bruce Horrocks Hampshire, UK
