Re: Kerning ignored on some macOS TTC fonts

FontForge > Elemente > Schriftinformationen > Nachschlagetabellen > GPOS > kern As I wrote, I can generate new TTF fonts with FontForge from Optima.ttc for example, use them instead and ConTeXt then has access to the kerning table (see attached PDF). I was just wondering if there is a way to use the TTC files directly with ConTeXt.

new upload
by Hans Hagen 04 Feb '25

04 Feb '25

Hi, NOTA BENE: The next upload is kind of special so best save the old tex tree if you update. For quite a while we have an extended expression scanner on board (in luametatex) and after recently testing it a bit more I decided to start using it. A side effect is that we can also use more clever assignments to dimensions and numbers. We already had: \scratchcounter 10 \scratchcounter = 10 \scratchcounter \numexpr 1 + 10\relax \scratchcounter \numexpression 1 + 10\relax etc but these expr have a potential lookahead problem, not so much when used liek this but when we have cases like \numexpr 1 + 10 - #1\relax because no one can predict what #1 is, maybe \numexp 1 - 10/5 which effectively is: \numexpr 1 + 10 - \numexp 1 - 10/5\relax which can run wild so in the end that is not suitable for use in key value situations. As part of our column set experiments we actually want to pass 'expressions', think \framed[height=2\lineheight-\strutdp]{...} or even \framed[height=2 * \lineheight - \strutdp]{...} or even \framed[height=2 * lh - sd]{...} etc. where the 2 * dimension is something not possibel with \dimexpr. So, to keep a long explanation short, we now also support \dimexpr{....} and also \scratchdimen{...} where in the later case we actually use \dimexpression{....} There's also \dimexperimental which has proper priority handler and can mix with integers and floats as well as limited boolean expressions (comparison) while its \numexperimental sibbling can also do bitwise operations. (Actually \dimexpression also can do some of that but one needs to use more ( ) around subexpressions; so \dimexpression conceptually sits between \dimexpr and \dimexperimental). Anyway, more about that in manuals and articles, and it's kind of old news already. The main impact is that now keys that refer to numbers and dimensions can also accept expressions without the need to be explicit, so width=3em + 2em * 4 lines=4 + (5*2 - 1) eventually will all be seen as {something} which as it is valid in assignments will trigger the right expression scanner. The \todimension and \tointeger primitives also accept {} because they scan for a dimension or number as again as side effect do all primitives and engine keyword that matter. They are serializers. Deep down context is now adapted to this: adding many {} in assignments, wrapping parameters in {} so that they can properly nest, replacing /removing redundant \dimexpr etc. All this can have introduced temporary issues but they can be fixed easily, so I think that the benefits outweight temporary issues. Think 'beta'. In case one wonders, there is no real impact on performance because expressions were already quite optimized and the (already kind of old) new scanners even more so. In due time more of the now possible features will be revealed.

Indenting the bullet in an itemize
by Kirill Davidov 04 Feb '25

04 Feb '25

Hello, I am trying to make an `intext` itemize list that has each item's first line, bullet included, indented just like the text. I can't seem to figure out which setting would allow me to do it. Is it possible? MWE: \setupindenting[yes, 2em, first] \setupitemgroup[itemize][intext] \startdocument \input lorem \startitemize \startitem \input lorem \stopitem \stopitemize \stopdocument

installing modules
by Charles Doherty 04 Feb '25

04 Feb '25

Dear all, I have installed ConTeXt standalone on a macbook pro Monterey OS 12.76 Intel machine (early 2015). I downloaded X86 and after install I get a folder context-osx-64 used sh install.sh and everything seems to work fine with TeXShop. I tried to download the modules using mtxrun --script install-modules --install —all I get a modules folder with files that are all like the first one below. 0C61CC4610D0FD8A2EBB2454500D59CBCD6936B85FC7841503E045662D0E737C.tma I am obviously doing something silly or using the incorrect syntax. Any help would be appreciated. Charlie Doherty

[t-vim] doesn't load, can't find `module-catcodes`
by Kirill Davidov 04 Feb '25

04 Feb '25

Greetings, I have been using `t-vim` more or less extensively and I have found that in some recent update it stopped loading. It fails to find and load `module-catcodes`, which apparently defines `\(un)protectmodulecatcodes`. Is there a workaround? I have tried replacing the special (un)protects with regular ones, but it didn't seem to get me further. Kirill

Kerning ignored on some macOS TTC fonts
by Paul Schalck 04 Feb '25

Hello, I'm trying to set up typescripts for a few classic TTC font collections shipped with macOS (see script below). No problems with: /System/Library/Fonts/Avenir Next Condensed.ttc /System/Library/Fonts/Avenir Next.ttc /System/Library/Fonts/Avenir.ttc /System/Library/Fonts/Supplemental/Charter.ttc /System/Library/Fonts/Supplemental/Futura.ttc /System/Library/Fonts/Supplemental/Seravek.ttc However, the kerning and the standard ligatures aren't picked up by ConTeXt on those: /System/Library/Fonts/Helvetica.ttc /System/Library/Fonts/HelveticaNeue.ttc /System/Library/Fonts/Optima.ttc /System/Library/Fonts/Palatino.ttc /System/Library/Fonts/Times.ttc /System/Library/Fonts/Supplemental/Baskerville.ttc /System/Library/Fonts/Supplemental/Bodoni 72.ttc /System/Library/Fonts/Supplemental/Didot.ttc /System/Library/Fonts/Supplemental/GillSans.ttc /System/Library/Fonts/Supplemental/Hoefler Text.ttc As an example, running mtxrun --script fonts --list --info --file Optima.ttc gives: mtx-fonts | mtx-fonts | mapping : 1 mtx-fonts | fontname : optimaextrablack mtx-fonts | fullname : optimaextrablack mtx-fonts | filename : /System/Library/Fonts/Optima.ttc mtx-fonts | family : optima mtx-fonts | weight : black mtx-fonts | style : normal mtx-fonts | width : normal mtx-fonts | variant : normal mtx-fonts | subfont : 5 fonts | otf loading | loading '/System/Library/Fonts/Optima.ttc', hash 'optima' otf reader | ignoring empty kern table of feature 'kern' fonts | otf loading | loading done fonts | otf loading | saving '/System/Library/Fonts/Optima.ttc' in cache system | lua | compiling '/Users/benutzer/.local/share/tex/texmf-cache/luametatex-cache/context/5fe67e0bfe781ce0dde776fb1556f32e/fonts/otl/optima.tma' into '/Users/benutzer/.local/share/tex/texmf-cache/luametatex-cache/context/5fe67e0bfe781ce0dde776fb1556f32e/fonts/otl/optima.tmd' system | lua | dumping '/Users/benutzer/.local/share/tex/texmf-cache/luametatex-cache/context/5fe67e0bfe781ce0dde776fb1556f32e/fonts/otl/optima.tma' into '/Users/benutzer/.local/share/tex/texmf-cache/luametatex-cache/context/5fe67e0bfe781ce0dde776fb1556f32e/fonts/otl/optima.tmd' stripped fonts | otf loading | loading, optimizing, packing and caching time 0.004 mtx-fonts | It seems that ConTeXt cannot find the kern values ("ignoring empty kern table of feature 'kern'").
