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

hi,list Thank you to all of you who have answered my questions in the past. I've recently basically finished my first macro package at ConTeXt, which can write exam papers. If anyone is interested in this feature, feel free to experience it. There may still be some problems with it, please let me know if you can. (I'm working on writing its description and use cases.) You can download it from the address below. 1. https://modules.contextgarden.net/cgi-bin/module.cgi/action=view/id=157 2. https://github.com/Soanguy/t-basicexam autumnus

whitespace inside synonym
by damien＠thiriet.web4me.fr 02 Jan '25

02 Jan '25

Hello, I am using the synonym mechanizm to design a glossary for my pupils. I am stuck with this: how can I insert a whitespace inside a synonym definition? What I achieved yet is: \definesynonyms [vocabulaire] [vocabulaire] [\LaDef] \starttext \vocabulaire{Unionpersonnelle}{Deux États sont en union personnelle lorsqu’ils ont le même souverain} \Unionpersonnelle\ \placelistofvocabulaire \stoptext I would like to typeset Union personnelle, without inserting a UTF-8 non breakable space. I tried {{Union personnelle}}, but don't know how may I escape the space in the macro. The answer may lay in lowlevel-macro, but I couldn't find it. Happy new year everyone! Damien Thiriet

Hi, It's about end of the year, so I updated lmtx. The most significant "change" is that columnsets are in the processed of being replaced which involves a "change in approach". As a consequence, when you use that mechanism - we're not sure how many actually do - and want the old code to kick in you need to load the "oldcolumnsets" module. Mikael S and I have been working on the new implementation but are not finished. We plan to have a reasonable stable version around may 2025 and a release at the ctx 2025 meeting when we also hope to have a new (additional) manual ready. We also test on real (complex) documents which triggers new challenges and solutions. The current code works ok but can best not be used for production (and some new features are undocumented anyway). Teaser: deep down the approach is quite different from the previous one but more reliable and it produced better quality output. Columnsets are also the mechanism that parallel document(stream)s will use. Like upgraded math and (multipass) paragraph optimization the mechanisms used are also a quite fundamental extensions that will be documented independently and likely used elsewhere.

issue when the encapsulation ‘startitem stopitem’ command is in another self-defined command
by autumnus 29 Dec '24

29 Dec '24

hi, I'm creating a command that can format multiple choice questions on my own. I've done most of it at the moment. But I want more, so I'm trying to create more versions of this command that is already nearing completion. So I'm using the following command to create a command with more possibilities. I've noticed that ‘startitem stopitem’ isn't working. Their location and serial number are anomalous. %%%% Removed some unnecessary commands to show what the problem was. % macros=mkvi \starttext \unprotect \installnamespace {chitem} \installcommandhandler \????chitem {chitem} \????chitem \appendtoks \setuevalue{\e!start\currentchitem}{\startnamedchitem [\currentchitem]}% \setuevalue{\e!stop \currentchitem}{\stopnamedchitem}% \to \everydefinechitem \tolerant\protected\def\markedchoice#1{{\sym{@} \red sym : #1}} \tolerant\protected\def\normalchoice#1{\startitem normal : #1\stopitem} \tolerant\protected\def\\calc_maxwidth#1{} %The longest option text is calculated by comparison to % determine the number of columns that can be typeset \tolerant\protected\def\startnamedchitem[#chitem]#*[#mark]#*[#option]#*#choice\stopnamedchitem% {\begingroup % \ifarguments 0\or :1\or +2\or =3\or !4\fi \def\currentchitem{#chitem}% \edef\p_correctmark{*}\edef\p_paramark{#mark}% \calc_maxwidth{#choice}% \ifx\p_paramark\p_correctmark \markedchoice{#choice}% \else \normalchoice{#choice}% \fi\endgroup} \def\stopnamedchitem{} \definechitem[chitem] \protect \startitemize[n,horizontal,two]% % The process of calculating the number of formattable columns % has been removed and the results of the calculations are used directly. \startchitem xxx\stopchitem \startchitem[*]correct choice\stopchitem \startchitem xxx\stopchitem \startchitem xxx\stopchitem \stopitemize \stoptext %%%%% thanks for any help, autumnus

No problems with this versions: current version: 2023.02.07 19:06 current version: 2024.04.01 08:59 Were there changes how we have to treat environment files? The error only occurs when I use "--mode=trimsize" but I cannot track down the error by removing environments with mode-specific definitions. The first environment file does not contain any mode-specific definitions. Any hints? TIA juh
