Hi, A week ago we had the (nice and pleasant) annual context meeting and as usual some new stuff has been presented there which was not yet in the distribution at that moment. Some pending code is now being moved into the distribution. Part is font related (lmtx only, not relevant for most users), most is metafun (luametafun or metafun xl or whatever name suits) related (including a new preliminary manual) which uses some new interfaces and therefore (currently) is lmtx only. At the meeting Mojca and Harald did some experiments with the whole range of raspberry pi's (as part of upgrading the compile farm with a pi 4). The outcomes can be found at https://meeting.contextgarden.net/2019/talks/2019-09-20-harald-pi/to_pi_or_… (There are some more slides there.) Because running tex on a 4 (with plenty of memory and an external ssd) is more reasonable than on the older models, I've added an lmtx installer for the pi. Some measurements with (really) simple runs show that performance is 3-4 times less than my laptop, which is not that bad (it helps that the 4 has a decent ethernet and usb3 bus); I don't know about more complex tests.

circuitikz meters
by Martin Althoff 01 Oct '19

01 Oct '19

Hello ... I am drawing some simple circuits for an electro-physics class I am teaching using circuitikz. Using meters gives some effects I don't quite understand. The MWE works as shown. The commented lines fail with "Undefined control sequence". If I put the same 3 lines into Latex (via Texstudio on Linux), just the opposite happens. The line with rmeter fails, the other two work. Why the difference? Some version issue? The "circuitikz manual version 0.9.4.pdf" shows all 3 types of meters as choice. Actually I would prefer to use the "ammeter" and "voltmeter" within Context. Thanks for any pointers. Greetings, Martin \usemodule[circuitikz] \starttext \starttikzpicture %\draw (0,0)to[ammeter, t=A, i=$i$] ++(3,0); \draw (0,4) to[rmeter, t=V, v>=$v$] ++(3,0) ; %\draw (0,2) to[voltmeter, l=$U$] (++3,2); \stoptikzpicture \stoptext Latex MWE, works as shown \documentclass{article} \usepackage{circuitikz} \begin{document} \begin{circuitikz} \draw (0,0) to[ammeter, t=A, i=$i$] ++(3,0); %\draw (0,4) to[rmeter, t=V, v>=$v$] ++(3,0) ; \draw (0,2) to[voltmeter, l=$U$] (++3,2); \end{circuitikz} \end{document}

Mkiv, fonts in text and math mode, with \definebodyfont
by Stefano Sanguinetti 01 Oct '19

01 Oct '19

Hello, I am trying to understand something more about fonts in text and math mode, in Mkiv Context. I would like to be able to change things at the "define body fonts" level. I tried the following, in order to have rsfs fonts : \setupbodyfont[12pt] \definebodyfont[12pt][rm][tf=rsfs10 sa *] \starttext \tf ABCD \tfa ABCD \stoptext The \tfa ABCD is displayed as rsfs as I wanted, but the \tf ABCD is displayed as default fonts. Why ? What could I change in order to have \tf ABCD in rsfs ? In math mode, I am not able to have rsfs fonts : \setupbodyfont[12pt] \definebodyfont[12pt][mm][mr=rsfs10 sa *,ex=rsfs10 sa *,mi=rsfs10 sa *,sy=rsfs10 sa *,ma=rsfs10 sa *,mb=rsfs10 sa *] \starttext $ABCD$ \stoptext That gives ABCD in default math mode fonts. Is there a simple way to do it with the \definebodyfont command ? Thank you in advance for your comments.

ConTeXt on current Debian
by Jan U. Hasecke 30 Sep '19

30 Sep '19

Dear all, todays upgrade broke my context installation (context and lmtx) as context now uses GLIBC_2.29 which is not available in Debian 10 buster. After using my backup I now wonder if from now on ConTeXt won't support Debian stable anymore? juh

Custom Footertext
by Jeroen 30 Sep '19

30 Sep '19

Dear list members, I am using the following environment file. The document itself is made-up of sections only. Instead of the section as footer, I would like to add a custom footer text throughout the document, starting at the second page as is the page numbering. I just don't seem to be able to adjust it. Who can help me out? Best Regards, Jeroen \startenvironment mkivcnotesenv \setuppapersize[A4,portrait] [A4,portrait] \setuplayout[backspace=20mm, width=175mm, topspace=20mm, header=0mm, footer=2mm, height=263mm, bottomheight=1mm, footerdistance=10mm] \usetypescript[pagella] \setupbodyfont[pagella,12pt] \setupcolors[state=start] \setuptype[style={\switchtobodyfont[11pt,tt]}] \setuptyping[style={\switchtobodyfont[11pt,tt]}] \setupfootertexts[section][] \setupfooter[alternative=,style=\bf\em] \setuppagenumbering[alternative=,location={footer,right},style=\bf\em] \setcounter[userpage][0] \setupcombinedlist[content][level=1] \setupexternalfigures[directory={images}] \stopenvironment

Multi-letter words/identifiers in math
by Shuxian Wang 30 Sep '19

30 Sep '19

Dear list, I am trying to typeset some multi-letter words/identifiers in mathematical formulas. Currently, doing things like `{\it variable}` or `{\mathit variable}` under math mode will cause the engine to shift all characters into the corresponding unicode mathematical alphanumeric block position. However, most OpenType fonts that have good support for unicode math are optimized for single-character usage. Therefore, the outcome of such method is non-ideal, as no kerning or ligatures will be enabled. Especially, this gives bad output when typesetting variable names with combinations like “ffi”. Looking through some past discussions on the list, I am aware of the usage of `\mathword` and `\mathtext`. Using those command will keep all the characters “as is” and typeset them under text mode (as far as I can tell). But those commands switch to the main body fonts temporarily to accomplish this. Sometime when using a different math font than the main font (like Palatino with Latin Modern Math), I wish my variable names can also be in the math font (or at least very similar, such as Latin Modern vs. Latin Modern Math) to better merge with the formula. The way I am currently doing is to introduce some “math text fonts” that is different from the main text font but close to the math font. And with custom font switchers like `\mwrm` and `\mwit` to help me define things like ``` \def\wordrm#1{\mbox{\mwrm #1}} \def\wordit#1{\mbox{\mwit #1}} ``` Am I missing some builtin functionalities or easier ways to do this? If not, would it be a good idea to extend the functionality of `\mathword` so it lifts out the restriction of only using the main text font? Thanks! Shuxian Wang

Hello there, I recently upgraded to ConTeXt ver: 2018.04.04 00:51 MKIV and found that the following simple code gives an error, where as it compiled without complaining in ver: 2017.05.15 21:48. \setupexternalfigures[location={local,default}] \starttext \input ward \placefigure[left,none]{}{\externalfigure[cow][width=3cm]} \input ward \stoptext The error happens when the location of placefigure is left or right, but not with center.
