Re: [NTG-context] problem with Segoe Ui Symbol as fallback font
by Jacob Kauffmann 04 Jan '23

Hi Hraban, I had a similar problem with math fallbacks (no errors, fallbacks not used) and just found a solution. Please find a small example below. I don't understand why we need the line \definefontfamily, but it's necessary for the fallbacks to work. Also, it stops working when I do \setupbodyfont[mainface,rm]. Cheers, Jacob \definefontfallback[cal-fallback][name:modern][uppercasescript,lowercasescript] \starttypescript[mainface] \definetypeface[mainface][rm][serif][palatino][default] \definetypeface[mainface][ss][sans] [modern] [default][rscale=1.075] \definetypeface[mainface][tt][mono] [modern] [default][rscale=1.075] \definetypeface[mainface][mm][math] [palatino][default][fallbacks=cal-fallback] \stoptypescript \definefontfamily[mainface][math][] \usetypescript[mainface] \setupbodyfont[mainface] \starttext {\rm \input ward } {\ss \input ward } {\tt \input ward } Should be Palatino: $x + y$ Should be Latin Modern: ${\cal I}$ $\mathcal{I}$ $\mathscr{I}$ \stoptext

lmtx upload
by Hans Hagen 04 Jan '23

04 Jan '23

Hi, I uploaded the first 2023 lmtx. There are not that many changes, most relate to updating manuals. Currently we're looking at the metafun / luametafun and lowlevel manuals - adding some accumulated todo's. Keep in mind that when we update manuals that is is not automatically reflected in new pdf's (processing happens outside the tree on temporary paths) and only occasionally I push back a pdf (when it looks ok). So, manual sources can be more up to date than manual pdfs. If you feel something (fundamental and stable) is missing you can let us know here. We gained some performance over the last month, mostly due to using different low level mechanisms (there are some more not yet widely used ones). The gain depends on (extreme) usage so quite likely most goes unnoticed unless one has many runs. After all, there are no fundamental changes in context, which is already reasonable optimized for ages (it's kind of a game to make it faster without obscuring the code, which is a criterium for rejection). As usual, (new and old) bugs will be fixed, Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | www.pragma-ade.nl | www.pragma-pod.nl -----------------------------------------------------------------

Dear List, The following example is from the mailing list: I would like to have double vertical Lines with $\Vert instead of \VL, and also \HL. How can I do this with an Math Modus? \setupcolors[state=start] \starttext \null\vskip15ex \hskip1em\framed[orientation=90,frame=off]{\bf Region}\blank\vskip-25.5ex \starttable[|c|l|r|r|r|r|r|r|r|] \DC \DC \DL[7] \DR \NC \NC \VL \use{7}\ReFormat[cB]{Years} \VL \AR \DC \DC \DL[7] \DR \NC \NC \VL \ReFormat[cB]{$<1$} \VL \ReFormat[cB]{$1-2$} \VL \ReFormat[cB]{$3-4$} \VL \ReFormat[cB]{$5-9$} \VL \ReFormat[cB]{$10-14$} \VL \ReFormat[cB]{$15+$} \VL \ReFormat[cB]{Total} \VL \AR \HL % \VL \offset[y=8ex]{\framed[orientation=90,frame=off]{\bf Region}} \VL East \VL 32 \VL 54 \VL 59 \VL 112 \VL 77 \VL 118 \VL 452 \VL \AR \VL \null\hskip2em\null \VL {\bf East} \VL 32 \VL 54 \VL 59 \VL 112 \VL 77 \VL 118 \VL 452 \VL \AR \VL \VL {\bf Midwest} \VL 31 \VL 68 \VL 68 \VL 120 \VL 63 \VL 173 \VL 523 \VL \AR \VL \VL {\bf South} \VL 53 \VL 92 \VL 93 \VL 158 \VL 106 \VL 158 \VL 660 \VL \AR \VL \VL {\bf West} \VL 41 \VL 56 \VL 67 \VL 78 \VL 45 \VL 86 \VL 373 \VL \AR \DC \DL[8] \DR \VL \VL {\bf Total} \VL 157 \VL 270 \VL 287 \VL 468 \VL 291 \VL 535 \VL 2008 \VL \AR \HL \stoptable \stoptext Many Thanks Uschi

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

issue with font
by Pablo Rodriguez 01 Jan '23

01 Jan '23

Hans, I have the following sample. \starttext \definedfont[TruetypewriterPolyglott-mELa.ttf] \input zapf \stoptext I get a fatal error in the font file (both LMTX and MkIV). Font is https://www.fontspace.com/truetypewriter-polyglott-font-f14955 (direct donwnload from https://www.fontspace.com/get/family/zmmx1) I don’t know what is wrong in the font, but it would be great to be able to use it with ConTeXt. Many thanks for your help, Pablo
