Nested itemize
by Alexandre Christe 22 Aug '23

22 Aug '23

Dear all, I'm struggling to setup a nested itemize with no blank line and several columns. What I mean is something like 1. a) bla c) bla b) bla d) bla The following MWE is my starting point \starttext \startitemize[n] \item \blank[-line] \startitemize[a,horizontal,two] [margin=2cm] \item First \item Second \item Third \item Fourth \stopitemize \item \blank[-line] \startitemize[a,horizontal,columns,two] \item First \item Second \item Third \item Fourth \stopitemize \stopitemize \stoptext Thanks in advance

Non-standard font alternatives
by Matthew McCabe 20 Apr '23

20 Apr '23

Hi list, I'm looking to import a font with medium and light weights (in this case Roboto) and define font alternatives so one can quickly switch to light text just as one would switch to bold text. There is a stackexchange answer from Wolfgang (https://tex.stackexchange.com/questions/303648/context-font-weights) which details a solution to this problem for ConTeXt MkIV but despite my best efforts I haven't been able to get things to work for me. There is the Roboto typescript example on ConTeXt garden but it isn't exactly what I'm looking for as for the document I'm making I would prefer to be able to treat the font weights as alternatives rather than separate families since I will be switching often. One can download the exact set of fonts I am using from https://fonts.google.com/specimen/Roboto Here is my code: \definefontalternative[lf] % light \definefontalternative[li] % lightitalic \definefontalternative[md] % medium \definefontalternative[mi] % mediumitalic \starttypescript [sans] [roboto] \definefontsynonym [SansLight] [file:Roboto-Light] [features=default] \definefontsynonym [SansLightItalic] [file:Roboto-LightItalic] [features=default] \definefontsynonym [Sans] [file:Roboto-Regular] [features=default] \definefontsynonym [SansItalic] [file:Roboto-Italic] [features=default] \definefontsynonym [SansMedium] [file:Roboto-Medium] [features=default] \definefontsynonym [SansMediumItalic] [file:Roboto-MediumItalic] [features=default] \definefontsynonym [SansBold] [file:Roboto-Bold] [features=default] \definefontsynonym [SansBoldItalic] [file:Roboto-BoldItalic] [features=default] \definefontsynonym [SansCaps] [file:Roboto-Sans] [features=smallcaps] \stoptypescript \starttypescript [sans] [roboto] \definebodyfont [default] [rm] [lf=SansLight sa 1, li=SansLightItalic sa 1, tf=Sans sa 1, it=SansItalic sa 1, md=SansMedium sa 1, mi=SansMediumItalic sa 1, bf=SansBold sa 1, bi=SansBoldItalic sa 1, sc=SansCaps sa 1] \stoptypescript \definetypeface[roboto][rm][sans][roboto][default] \setupbodyfont[roboto] \starttext \lf Light \li LightItalic \tf Regular \it Italic \md Medium \mi MediumItalic \bf Bold \bi BoldItalic \sc SmallCaps \stoptext - The result is entirely in the regular weight default font: What I've tried: 1. I've tried a great deal of alternative \definefontsynonym arguments such as specifying by name, including the full path to each ttf file 2. I played around with different two character \definefontalternative arguments to ensure there was no overlap with existing commands (as far as I am aware the existing set are otherwise undefined) A few things to note: 1. My current version of ConTeXt is 2022.12.09 16:34 2. For portability I have included the ttf files for Roboto in a directory within my project directory and while setting things up I set OSFONTDIR to include this directory and run `mtxrun --script fonts --reload --force` 3. `mtxrun --script fonts --list --all --pattern=Robo` yields: identifier familyname fontname filename subfont instances roboto roboto robotoregular ./fonts/Roboto/Roboto-Regular.ttf robotoblack roboto robotoblack ./fonts/Roboto/Roboto-Black.ttf robotoblackitalic roboto robotoblackitalic ./fonts/Roboto/Roboto-BlackItalic.ttf robotobold roboto robotobold ./fonts/Roboto/Roboto-Bold.ttf robotobolditalic roboto robotobolditalic ./fonts/Roboto/Roboto-BoldItalic.ttf robotoitalic roboto robotoitalic ./fonts/Roboto/Roboto-Italic.ttf robotolight roboto robotolight ./fonts/Roboto/Roboto-Light.ttf robotolightitalic roboto robotolightitalic ./fonts/Roboto/Roboto-LightItalic.ttf robotomedium roboto robotomedium ./fonts/Roboto/Roboto-Medium.ttf robotomediumitalic roboto robotomediumitalic ./fonts/Roboto/Roboto-MediumItalic.ttf robotonormal roboto robotoregular ./fonts/Roboto/Roboto-Regular.ttf robotoregular roboto robotoregular ./fonts/Roboto/Roboto-Regular.ttf robotothin roboto robotothin ./fonts/Roboto/Roboto-Thin.ttf robotothinitalic roboto robotothinitalic ./fonts/Roboto/Roboto-ThinItalic.ttf 4. Using `\definedfont[name:robotomedium*default] hello` and `\definedfont[file:Roboto-Thin*default] hello` (for example) work exactly as expected I hope this isn't a silly question, I'm very new to ConTeXt and have been struggling for a while so thought I may as well ask in case there's something I'm missing, would appreciate any guidance :) Regards, Matt

new uplaod
by Hans Hagen 17 Apr '23

17 Apr '23

Hi, I uploaded a new lmtx. Again some updated math of which details will be revealed later. Apart from some details we added suport for fourier notations. There are no high level definitions yet as we have to invent names but this is how it works (private unicode slots might change): \setupbodyfont[pagella] \starttext \setupmathdelimited [topoffset=.2\exheight] \definemathdelimited [fourier] [rule=no, left=\zerocount, right="FE944] \definemathdelimited [courier] [rule=no, left=\zerocount, right="FE946] \definemathdelimited [xourier] [rule=no, left=\zerocount, right="FE948] $ \fourier{(z+1)} $ $ \fourier{(z+1)} + \sqrt[2]{1}$ $ \fourier{(z+1)} + \courier{(z+1)} + \xourier{(z+1)} $ $ \fourier{\left(z+\frac12\right)} + \courier{\left(z+\frac12\right)} + \xourier{\left(z+\frac12\right)} $ $ \autofences \fourier{(z+\frac12)} + \courier{(z+\frac12)} + \xourier{(z+\frac12)} $ $ \widehat{x^2 + 2x + 2} $ \stoptext This example also shows a new \autofences feature and widehats (widetilde and widecheck also work that way) that overcome limitations in fonts, so \def\CrappyHack#1{\im{#1{a} + #1{a+b} + #1{a+b+c} + #1{a+b+c+d} + #1{a+b+c+d+e} + #1{a+b+c+d+e+f}}\par} \CrappyHack\widehat \CrappyHack\widetilde \CrappyHack\wideacute \CrappyHack\widecheck will work. For thise in finance we now have $ \annuity{x + 1} + \lannuity{x + 1} + \rannuity{x + 1} + \lrannuity{x + 1} $ these are basically radicals (like sqrt) with two sided symbols.

Re: [NTG-context] \typefile not including file and returning success

It's a workaround at least. But context returning success when it clearly doesn't include the file is unfortunate. The missing file might go completely unnoticed. I'd expect an error there. Marco

pgfplots module wrecks in latest
by Gavin 24 Jan '23

24 Jan '23

Hi List, The TikZ related module “pgfplots” is causing a fatal error in the latest ConTeXt. Here is a MWE: \usemodule[tikz] \usemodule[pgfplots] % PGFPlots module for graphs \starttext \starttikzpicture \draw (0, 0) circle (3cm); \stoptikzpicture \stoptext Without loading the pgfplots module, this draws a circle. With the \usemodule[pgfplots] line, this has the error below before doing anything. I don’t know when this started happening, because I don’t use pgfplots often, but it was probably in the last couple months. Thanks for all the great updates! Gavin tex error > tex error on line 521 in file pgfplots.code.tex: Use of \pgfplots@command@to@string@@ doesn't match its definition <inserted text> m acro:colormap <argument> \pgfplots@colormap@catcodemagic <macro> \pgfplots@command@to@string #1#2->\expandafter \pgfplots@command@to@string@@ \meaning #1 \pgfplots@EOI {#2} <line 6.521> \pgfplots@command@to@string\pgfplots@colormap@catcodemagic\pgfplots@colormap@catcodemagic <empty file> If you say, e.g., '\def\a1{...}', then you must always put '1' after '\a', since control sequence names are made up of letters only. The macro here has not been followed by the required stuff, so I'm ignoring it.

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

\autoinsertedspace fails
by Rik Kabel 06 Jan '23

06 Jan '23

Happy New Year all! Following up on the problem with \autoinsertnextspace (https://mailman.ntg.nl/pipermail/ntg-context/2022/107111.html) and the new \autoinsertedspace that came from that report, I see that there is still a problem, or perhaps a problem again after it was previously repaired. The following code, run under the latest (and recent previous) version, produces an incorrect result, with no space inserted where expected in many cases. As the first examples after \starttext show, the problem appears to be with \autoinsertedspace, but perhaps I am using it incorrectly in the macro as well. \starttexdefinition unexpanded BD \dodoublegroupempty \doBD \stoptexdefinition \starttexdefinition doBD #1#2 \removeunwantedspaces\ % insert a space ( \ifsecondargument #1|–|#2 \else\iffirstargument #1– \else {\red I NEED A DATE OR DATES!} \fi\fi ) \autoinsertedspace \stoptexdefinition \tt \starttext This\autoinsertedspace fails unexpectedly with autoinsertedspace.\par This\autoinsertedspace \emph{fails unexpectedly} with autoinsertedspace.\par This\autoinsertnextspace works with autoinsertnextspace.\par This\autoinsertnextspace \emph{fails} as expected with autoinsertnextspace.\par Saussure\BD{1857}{1913} works.\par Saussure \BD{1857}{1913} \emph{works}.\par Saussure \BD{1857}{1913}.

Ajami script

I just read this: https://www.bu.edu/articles/2022/fallou-ngom-discovers-ajami-african-writin… And now I’d like to know if ConTeXt is capable of typesetting this variant of Arabic. (Just out of curiosity, I can’t read any Arabic and don’t know any African language.) Hraban

numbering questions
by Henning Hraban Ramm 01 Jan '23

01 Jan '23

A happy new year to everyone! I’m playing with some examples of section numbering. * Is there a setup to influence the order of number segments? I.e. can I have “section.chapter.part“ instead of “part.chapter.section”? * How can I format the segments, e.g. to get two or three digits each (leading zeros)? * I can force a section number with “ownnumber”, but the next one is back in the previous scheme. Itemize has “start”. How can I start section chapter numbering at 3 (or -1 or whatever; I know I can start at 0 with “zero”) and let ConTeXt continue from there? My example tries to (ab)use the section numbering for a date (e.g. for a diary): ----- \definestructureconversionset[default][n,n,month,n][n] \definestructureseparatorset [default][-,-,-,-] \definehead[Year][chapter] \definehead[Month][section] \definehead[Day][subsection] \define[2]\TitleCmd{#1} % number only \setuphead[Year,Month,Day][number=yes,page=no,command=\TitleCmd] \setuphead[Year][page=yes] %\setuphead[Month][] \setuphead[Day][style={\ss\bf}] \def\Dummycontent{ \dorecurse{12}{ \startMonth New Month. \dorecurse{5}{ \startDay Another day. \stopDay } \stopMonth }} \starttext \startYear[ownnumber=2023,title=This] A new year begins. \Dummycontent \stopYear \startYear Next year. \Dummycontent \stopYear \stoptext ----- Hraban
