MP scratch counter
by Henning Hraban Ramm 13 Jul '22

13 Jul '22

Hi y’all, this is a scratch counter from the simpleslides module. It doesn’t work any more (always shows max-1), and I guess it used to. What’s wrong? Hraban """ \startuseMPgraphic{MP:ornament} StartPage ; save a,b ; numeric a,b ; a = 7mm ; b = PaperWidth/2 - NOfPages * 2.5pt ; save p,q; path p,q ; p =((0,5mm) -- (1mm,11mm)) shifted (b,0) ; q =((-8mm,5mm) -- (0,11mm) ) shifted (b,0) ; pickup pencircle scaled 3pt ; for i := NOfPages-1 downto 1: draw (if i mod 5 = 0 : q else : p fi) shifted (i*5pt, 0pt) withcolor if i < PageNumber : red else : black fi ; endfor ; StopPage ; \stopuseMPgraphic \defineoverlay[background:ornament][\useMPgraphic{MP:ornament}] \setupbackgrounds[page][background={background:ornament}] \setupbodyfont[ss,18pt] \starttext \dorecurse{10}{ \strut\par \page } \stoptext """

New math additional requirement for font definitions
by Alexandre Christe 13 Jul '22

13 Jul '22

Dear list, I've come across that the new math (which by the way looks really nice) requires some additional properties to be set in the font definition. If I take the example file provided by Mikael and add the following lines \usetypescriptfile[alegreya] \setupbodyfont[alegreya,11pt] It fails with the following error message: "tex error on line 16 in file /Users/aleks/Desktop/Test Context/someformulas.tex: Math error: parameter 'limitbelowbgap' with id 36 in style 0 is not set" Libertinus works fine by adding the following two lines \usetypescriptfile[libertinus] \setupbodyfont[libertinus,11pt] Could someone enlighten me? The font definition file is attached. BR, Alex

Bug in placeformula
by Otared Kavian 13 Jul '22

13 Jul '22

Dear Hans, dear Mikael, In my experiments with the new math engine, I noticed that there is an issue with \placeformula when one sets the location of the numbers on the left: the number is one line above the formula. Here is a minimal example: % begin bug-placeformula-left.tex \setupformulas[location=left] \starttext \placeformula \startformula a^2 + b^2 = c^2. \stopformula \stoptext % end bug-placeformula-left.tex Moreover, in some environments (such as enumerations) the bug destroys completely the flow of text but I could not set up a minimal example to send you. Best regards: Otared

regular online meet-up
by Henning Hraban Ramm 13 Jul '22

13 Jul '22

You’re invited to join this Wednesday, July 13th, 15:00 CEST (UTC+2) at https://lecture.senfcall.de/hen-rbr-rku-oke ConTeXt users of all levels are welcome! Hans will probably give a Q&A session again – please announce subjects you’d like to discuss ASAP, so that he can prepare. (I guess we’ll get to see some more math magic...) (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, 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

fullhz, kerning and glue
by Henning Hraban Ramm 12 Jul '22

12 Jul '22

Hi, I just added an explanation of "fullhz" to the options in https://wiki.contextgarden.net/Command/setupalign. but I’m actually unsure if it’s right. In the sources I found: https://source.contextgarden.net/tex/context/base/mkxl/hand-ini.mkxl %D At some point we can introduce extreme expansion, i.e. \type {\normaladjustspacing\plustwo}. 56 57% 0 = disabled 58% 1 = notused (thesis) 59% 2 = glyph + kern 60% 3 = glyph only (default) 61 62\def\font_expansion_enable {\normaladjustspacing\plusthree} 63\def\font_expansion_enable_k{\normaladjustspacing\plustwo} 64%def\font_expansion_enable_n{\normaladjustspacing\plusone} 65\def\font_expansion_disable {\normaladjustspacing\zerocount} And "fullhz" in spac-ali.mkxl calls \font_expansion_enable_k. So, apparently fullhz enables stretching of *kerning* – that sounds to me like letterspacing. OTOH in my notes (and thus in my book) I have the information that fullhz enables stretching of *glue*, and I thought that would mean whitespace outside of words. Please enlighten me? Hraban

LMTX and modules
by Axel Kielhorn 12 Jul '22

12 Jul '22

Hello, Some years ago I wrote an introduction to ConTeXt in German: https://github.com/AKielhorn/Context-Intro But that was long ago. Today LMTX is state of the art and I tried to build it with a recent LMTX. This lead to problems because LMTX does not include modules. Therefore my question is: Is the a plan to include modules into the regular LMTX installation? If not, is there a way to test for a certain module? \doiffileexists{m-module} \usemodule{module} Greetings Axel

lmtx \placeinitial with nonzero par indent?
by Michael Urban 12 Jul '22

12 Jul '22

The following produces different results in mkiv and lmtx (to which I am brand new): \setupinitial[distance=1pt,font=Serif at 36pt,n=2] \setupindenting[medium,yes] \starttext \placeinitial \input knuth \stoptext The mkiv output is the desired effect. It works fine in lmtx if I do not change to medium indentation. Is this a bug or a feature (i.e., should I change something to work properly in both environments)?

numbering sections/subsections
by Alan Bowen 11 Jul '22

11 Jul '22

I’m trying to get my sections numbered with capital letters and my subsections with Arabic numbers. So far, no joy. What am I missing? Alan Mwe: with ConText ver: 2022.01.21 20:13 LMTX fmt: 2022.2.1. (The problem persists when I run ConTeXt online) \setuphead[section][conversion=A] \setuphead[subsection][conversion=n, sectionsegements=section:subsection, stopper={.}] \starttext \startsection[title=New section] \input knuth \startsubsection[title=New subsection] \input ward \stopsubsection \stopsection \stoptext

Prolongation of the sidebar to the footnotes.
by Joaquín Ataz López 11 Jul '22

11 Jul '22

Good morning everybody, I am composing a text in which there is a sidebar environment in whose text some footnotes are included. If the environment ends before the page, the sidebar stops at the point where the environment ends, and does not reach the area where the footnotes are. On the other hand, if the environment extends to the next page, the sidebar goes all the way to the bottom of the page, crossing the footnotes, which causes an unaesthetic effect. Does anyone know how I could avoid this effect? -- --------------------- Joaquín Ataz López Derecho civil Universidad de Murcia ---------------------

Re: [NTG-context] Workshop at FrOSCon

> From: juh+ntg-context(a)mailbox.org > My main problem is that I never used Windows in my life and have no idea > how to help people with installing lmtx on this platform. > > juh I'm a beginner in context (and not a programmer by profession) and installing lmtx on windows was very easy for me. the steps are on the wiki https://wiki.contextgarden.net/Installation and it is as easy as it is written there. I've been using context thanks to these installation steps on win 7 and win 10. I'm not sure what the targetgroup at the conference is, but if the people there ever used a commandline, they should be good to go. once you install, you open the commandline using Win+R and then type "cmd". Once in the cmd, you only need to know the command "cd" (change directory) to navigate to the folder where the .tex source is, so e.g. "cd c:\users\x\documents\" and then run "context test.tex". That is the manual way. I use sublimetext as text editor and made a new build for it, that when I press Ctrl+B saves all changes in the open file/folder and runs context on the open file and previews the pdf in mupdf that is zoomed to be 1:1 paper:print on my dpi. It's a bit like TeXworks, just press button and see the pdf, because mupdf automatically overwrites the open pdf without asking. It's 4 hours by train for me to Bonn and I'm not sure whether I'm a good candidate to teach people context due to my low skill, but I can surely teach you how to install lmtx on windows if you like (we could call or sth). Best, Andrej
