Problem with LMTX on macOS: no format file given, quitting
by Tommaso Gordini 13 Feb '23

13 Feb '23

Hello list, I am writing to you about a problem with ConTeXt LMTX and TeXShop 5.11 on macOS 12.6.3 (MacBook Air M2). Yesterday I installed LMTX on my computer following the instructions here: https://wiki.contextgarden.net/Installing_ConTeXt_LMTX_on_MacOS The LMTX tree is correctly installed in the directory I've chosen: charlie@Air-di-Tommaso ~ % which luametatex /Users/charlie/Documents/ConTeXt/ConTeXt-LMTX/tex/texmf-osx-arm64/bin/luametatex charlie@Air-di-Tommaso ~ % type luametatex luametatex is /Users/charlie/Documents/ConTeXt/ConTeXt-LMTX/tex/texmf-osx-arm64/bin/luametatex charlie@Air-di-Tommaso ~ % luametatex --version This is LuaMetaTeX, Version 2.10.06 Execute 'luametatex --credits' for credits and version details.

Functionality : level 20230126 Support : context(a)ntg.nl Copyright : The Lua(Meta)TeX Team(s) (2005-2022+) The LuaMetaTeX project is related to ConTeXt development. This macro package tightly integrates TeX and MetaPost in close cooperation with Lua. Updates will happen in sync with ConTeXt and when needed. Don't be fooled by unchanged dates: long-term stability is the objective. However, I also get this: charlie@Air-di-Tommaso ~ % luametatex startup error : no format file given, quitting Also, I created the TeXShop engine as indicated on the page (I've done it before with no problems). However, now when I run LMTX from editor to compose a source, the source is compiled with MkIV Standalone, which I have in another folder ( /Users/charlie/Documents/ConTeXt/ConTeXt-MkIV). LMTX doesn't even work from a terminal, of course. The curious thing is that even by launching the ConTeXt present in TeX Live, what really works is always MkIV Standalone. Do you have any idea where I might have gone wrong? Thank you very much Tommaso

Problem using \scale
by Bruce Horrocks 10 Feb '23

10 Feb '23

I'm printing address labels. Sometimes an address has a long line that is too long to fit on the label with the result that it wraps. Instead of wrapping, I thought it would be nice to try and auto-scale the label and shrink it so that the long line just fits. I'm using \crlf to break the address into lines and this doesn't play well with the \scale command, see MWE below, where the second frame is just one long line as the \crlf's seem to be ignored. Is there a simple solution that allows \crlf and also scale? \starttext \startbuffer[address] Name \crlf Address 1 \crlf A long line that wraps \crlf Town \crlf Postcode \stopbuffer \framed[width=3cm,align=flushleft]{\getbuffer[address]} \framed[width=3cm,align=flushleft]{\scale[factor=fit]{\getbuffer[address]}} \stoptext — Bruce Horrocks Hampshire, UK

issue with custom hyphenator

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 ..

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.

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

[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 -----------------------------------------------------------------
