Typescripts
by Tommaso Gordini 06 Feb '25

06 Feb '25

Hello everyone. Some time ago, I found a web page that contained dozens of ready-to-use typescripts. Some were signed by Hans. I realize that my request is very imprecise, but I ask you anyway if you could point me to it. Many thanks. Ciao Tommaso

images with alt text
by Steffen Wolfrum 06 Feb '25

06 Feb '25

Hi, as publishing houses (at least in Germany) are forced to provide «alt text» with their PDF-publications (from June 2025 on), I need to know how «images with alternate text» (https://en.wikipedia.org/wiki/Alt_attribute) are typeset with ConTeXt LMTX. In HTML it looks like this: <img src="example.jpg" alt="Example text"> What is the equivalent in ConTeXt LMTX? Yours, Steffen

New Mac Mini Font Issue
by Mike Urban 06 Feb '25

06 Feb '25

I have re-installed texlive 2024 and context on my Mac Mini. Things are generally working OK; but I am seeing these error messages: mathematics > initializing > font 'LatinModernMath-Companion.otf' doesn't exist mathematics > initializing > font 'LatinModernMath-Companion.otf*tweakreplacealphabets1' doesn't exist What needs to be installed or rebuilt for this?

Re: Kerning ignored on some macOS TTC fonts
by Paul Schalck 05 Feb '25

> Why do you think these fonts have kern tables at all? > I looked at Optima.ttc with Fontforge and can’t find one. On my system, they do have kerning values. 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

Dear List, I have a little example. \setuppapersize[A4] \setupinteraction[state=start] \setcounter[userpage][100] \setupbodyfont[modern, 12.50pt] \starttext Das bin ich \footnote[Das auch]{Hier bin ich} \stoptext I would like to have footnumber 4 on this page. How can I do that? Many thanks Uschi
