Change in \vec behavior
by Jean-Philippe Rey 22 Jan '23

22 Jan '23

Hello, As I usually do at the end of each year, I upgraded my ConTeXt installation. I noticed a change in \vec behavior which doesn't extend the arrow anymore. Here is my example: \starttext Engine: \texenginename\ \texengineversion \ConTeXt: \contextversionnumber \type{$\vec{AB}$} : $\vec{AB}$ \stoptext The result with the latest ConTeXt version: and with the version from a year ago: I am aware that I could use \overrightarrow, but I prefer the shape and position of the \vec arrow, especially with single letters. What is the rationale for the change in \vec? Is there a way to get the previous behavior back? Thanks, -- Jean-Philippe Rey jean-philippe.rey(a)centralesupelec.fr 91192 Gif-sur-Yvette Cedex - France Empreinte PGP : 807A 5B2C 69E4 D4B5 783A 428A 1B5E E83E 261B BF51

Dear list, using current latest (from 2023.01.15 14:04), the just released version of Source Serif 4 Variable (https://github.com/adobe-fonts/source-serif/releases/latest) and the following sample: \usemodule[fonts-variable] \starttext \showfontvariations[font=file:SourceSerif4Variable-Roman.otf] \stoptext ConTeX outputs no text with that font. Could anyone confirm the issue? Many thanks for your help, Pablo

Why won't custom indexes work when the value comes from \getvalue?
by Joel 21 Jan '23

21 Jan '23

I setup a custom index like this (see minimum example code below): The problem is, when I try to create an index entry, using \setcoreidea, but place \getvalue inside, it won't render, ex.: \setcoreidea{\getvalue{secret1}} As you can see in this sample code, \setcoreidea will work fine, but when \getvalue{} is placed inside, it can't find the value. Any suggestions? --Joel \defineregister[coreidea][compress=yes]\setupregister[coreidea][style=sansbold, textstyle=slanted, n=2, pagenumber=yes, indicator=no] \define[1]\setcoreidea{% \coreidea{#1}% } \setvalue{secret1}{this won't work} \starttext % \setcoreidea{this works} \input knuth \input knuth \input knuth \input knuth \setcoreidea{\getvalue{secret1}} \startchapter[title=Core Ideas] \placecoreidea \stopchapter \stoptext

What's the current method for using a variable font in Context and Metapost?
by Guido Bartolucci 20 Jan '23

20 Jan '23

I haven't been able to find working examples. Here is some sample code. I would really like to be able to use the light variation of this DIN-like font. \usemodule[fonts-variable] \definefontfamily [mainface] [ss] [bahnschrift] \setupbodyfont[mainface] \starttext \ss 123456789 Wild! \medskip \startMPcode picture pic; pic := thelabel("This is in Metafont 0123456789", (0, 0)); draw pic; \stopMPcode \stoptext

A new version of the PocketDiary module and a collection of examples for creating calenders
by Willi Egger 20 Jan '23

20 Jan '23

Hi everybody, I uploaded a new version of the PocketDiary module to the ConTeXt garden. The version 2.2 is providing the calendar functionality as it is presented in PocketMods (https://pocketmod.com/) It includes day, week, month and year tables. There are two variations of the outcome. The first is that the module creates a week calendar with eahc working day on one page and the weekend on one page. The other version allows to setup an individual setup of the pages. This module also comes with a couple of templates for general information keeping. The new version includes also sun and moon data calculations. The latest version now calculates the Daylight Saving Time automatically for America and Europe or none if desired. Next to this I uploaded a collection of calendars based on the PocketDiary module’s machinery. These calendars are typeset either as A6 or A5 sized pages printed on A4 paper and impositioned for making books.. There is also a photo-calender on A4 paper. Calendar types included are: year calendar with 1 day per page, year calendar with 1 week on two facing pages, a menu calendar and a sun and moon data calendar. Also included in this collection is a so called date-driven list generator. This allows to produce lists with any kind of date interval in days for any duration. It allows to adjust the number of columns in the list as well as changing the column heads to the requirements of the list. I hope that some of you might find this helpful. Kind regards Willi

Re: [NTG-context] bug $\vec{}$
by Jacob Kauffmann 20 Jan '23

20 Jan '23

Not sure if this is related in any way, but \overset behaves weirdly with the equal sign: \startformula \overset{weird}{=} \stopformula (workaround/solution is \overset{weird}{\mathop{=}}, or \mathop{=}^{weird})

wider font effect as font feature?
by Pablo Rodriguez 20 Jan '23

20 Jan '23

Dear list, I wanted to use a font with slightly wider effect, such as in: \definetweakedfont[wider][xscale=1.075] Is there any way that it could be applied as a font feature? Or how could I apply this effect everytime a \definefontfamily is used? Many thanks for your help, Pablo

Minor bug in Lua or ConTeXt
by Bruce Horrocks 18 Jan '23

18 Jan '23

ConTeXt ver: 2023.01.04 The following MWE won't compile because of the \dummycommand line even though it is a comment. Not sure whether it's a minor bug or an unavoidable aspect of allowing embedded Lua. \startluacode -- \dummycommand \stopluacode \starttext Hello \stoptext — Bruce Horrocks Hampshire, UK
