Hi, Please find attached a new version of the module, with some ideas from Marco. Later, I'll upload it to modules.contextgarden.net. Here a usage example: \usemodule[downsample] \setupexternalfigures[ location=default, % find hacker.jpg and mill.png cache=/tmp, % where to put the low resolution images resolution=50, % resolution in DPI conversion=downsample.pdf] % use this module \starttext \externalfigure[hacker][width=0.4\textwidth] \setupexternalfigures[resolution=20] \externalfigure[mill][width=4in, height=3in] \setupexternalfigures[resolution=200] \externalfigure[mill][width=4in, height=3in] \stoptext Hans, it would be nice, to apply this patch, to trigger new conversion, when figure dimensions change: --- grph-inc.lua~ 2019-02-14 17:04:12.000000000 +0100 +++ grph-inc.lua 2019-02-17 08:45:38.129971581 +0100 @@ -864,6 +864,14 @@ newbase = prefix .. newbase end local hash = "" + local width = figures.current().request.width + local height = figures.current().request.height + if width then + hash = hash ..

PDF/UA-2, WTPDF
by Henning Hraban Ramm 20 Sep '24

20 Sep '24

Quoting a post by Philipp Kiff, https://mastodon.social/@pkiff/112219488889350928: In amongst the release of PDF/UA-2 (PDF for Universal Accessibility) and the new Well-Tagged PDF (WTPDF) standard last month, some PDF professionals may have missed two other new resources that may help explain and view them: 1. Questions and Answers about Tagged PDF from PDF association 2. Acrobat Custom File Info Panels by Peter Wyatt Last month saw the release of PDF/UA-2 and the new Well-Tagged PDF (WTPDF) standard - neither of which revokes PDF/UA-1. And none of those are the same as PDF 1.7 vs 2.0. To many, the landscape of PDF specs may now seem littered with confusing acronyms and versions! For some help disentangling it all, the PDF association has a Questions and Answers about Tagged PDF: https://pdfa.org/resource/tagged-pdf-q-a/ In related news, Peter Wyatt released Acrobat Custom File Info Panels. This is a free extension for Acrobat that adds new panels to the XMP metadata shown when you view File > Properties in Acrobat Pro. The new panels allow you to view the additional conformance claims and dated revisions of ISO standards that can now be included in PDFs, but that aren't currently visible in the standard Acrobat panels. https://pdfa.org/discovering-pdf-metadata/ One thing I realized in reading through the new standards and looking at various sample files this week is that I should probably spend some time learning LaTeX! Both LaTeX and LibreOffice are already capable of producing PDF/UA-2 files, and with some tweaking, LaTeX can produce what appear to be really good WTPDF files. Kudos to both those development teams! https://github.com/latex3/tagging-project/discussions/72 Finally, in case you missed earlier posts from last month, here are links to the official sources for the two new PDF standards that these other resources relate to: 1. PDF/UA-2 https://pdfa.org/iso-14289-2-pdfua-2/ 2. Well-Tagged PDF (WTPDF) https://pdfa.org/wtpdf/

x mark symbol and general symbol guide
by Gerion Entrup 16 Jun '24

16 Jun '24

Hi, I recently tried to typeset a table with checkmarks and x marks. \checkmark exists but is there a predefined x mark symbol (\xmark does not work)? In general: For LaTeX there exists the very helpful comprehensive LaTeX symbol list [1]. Is there a similar documentation for ConTeXt somewhere? Best, Gerion [1] https://www.ctan.org/pkg/comprehensive

Wiki - test/proposal to further clarify documentation
by garulfo＠azules.eu 19 May '24

19 May '24

Hi all, I just discover the Diátaxis documentation framework : - https://www.diataxis.fr/ - 30min video : "What nobody tells you about documentation", https://www.youtube.com/watch?v=t4vKPhjcMZg , from Daniele Procida at PyCon 2017 As I understand it, it can help both readers and writers of the documentation by clarifying the purpose of each element. So I started a potential new "welcome page" : https://wiki.contextgarden.net/Main_Page2 The main lines would be : - Tutorials: installation pages, step by step examples - How-to guides: most of the existing wiki pages which are not https://wiki.contextgarden.net/Commands/ ... - Discussions and manuals: most of the existing manuals - Reference : the pages dedicated to commands which already include link to mailing list, stack exchange, ConTeXt's source - https://wiki.contextgarden.net/Category:Commands - https://wiki.contextgarden.net/Special:PrefixIndex?prefix=Command%2F To match the logic of Diátaxis, maybe some material from command pages should be moved from "Reference" to "How-to guides", for example, when the examples go beyond "pure description" and begin to deal with "how-to" cases, e.g. : - Reference for setuphead: https://wiki.contextgarden.net/Command/setuphead - How-to guides for headings: https://wiki.contextgarden.net/Titles If it make sense, and according to your feedbacks, I can continue to reallocate existing contents. Thanks for your feedback and thoughts. Garulfo

Hbox error with itemized list on second page
by Ross Schulman 14 May '24

14 May '24

Hello, I'm attempting to format a resume in Context building off of a template I found online. I'm having an odd error with some bullets on the second page, however. I'm guessing it has something to do with my \definelayout for the second (and subsequent) pages, but I can't figure it out for sure. What is happening is that whichever bullets are at the top of the second page are being wrapped as if they were appearing on the first page, which has a different layout structure. I've pasted a sanitized version of the tex file below. Any assistance would be greatly appreciated!

\par and \startlines
by denis.maier＠unibe.ch 01 May '24

01 May '24

Hi, I'm trying to typeset a poem from XML, but I can't figure out how to make the inbetween key working here. As the source is XML, I cannot just add an empty line to start a new group of lines inside \startlines...\stoplines. I guess, there must be a command to do that, but \par seems to have no effect here. How can this be done? Best, Denis %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% \setuplines[before={\blank},after={\blank},inbetween={ARE WE INBETWEEN?\blank}] % XML Nodes auswählen \startxmlsetups xml:test \xmlsetsetup{#1}{*}{-} \xmlsetsetup{#1}{doc|poem|stanza|line}{xml:*} \stopxmlsetups \xmlregistersetup{xml:test} \startxmlsetups xml:doc \xmlflush{#1} \stopxmlsetups \startxmlsetups xml:poem \startlines \xmlflush{#1} \stoplines \stopxmlsetups \startxmlsetups xml:stanza \xmlflushlinewise{#1}\par %this has no effect \stopxmlsetups \startxmlsetups xml:line \xmlflush{#1} \stopxmlsetups \startbuffer[test] <?xml version='1.0' standalone='yes?> <doc> <poem> <stanza> <line>The</line> <line>lines</line> <line>are</line> <line>there!</line> </stanza> <stanza> <line>The</line> <line>lines</line> <line>are</line> <line>there!</line> </stanza> </poem> </doc> \stopbuffer \starttext This works: \startlines The lines are there!

Font switching for titles and subtitle not working as expected ?
by denis.maier＠unibe.ch 30 Apr '24

30 Apr '24

Hi, I just jumbled upon this question on tex stackexchange : https://tex.stackexchange.com/questions/715799/context-switching-font-for-b… Using the style key as suggested in the accepted answer works, but I've had a look in to this, and I don't understand why the original code does not work. I've also tried to find a solution using textcommand instead of command, but that makes no difference. Only one setting will be accepted. As soon as both, titles and subjects, are changed only the first change will be accepted. Is this a bug, or am I missing something? Best, Denis %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% % Original MWE \define[2]\mytitle{% \switchtobodyfont[chorus]% #2 } \define[2]\mysubject{% \switchtobodyfont[chorus]% #2 } \setuphead[title][command=\mytitle] \setuphead[subject][command=\mysubject] \starttext \title{In Zapf Chancery} \subject{Apparently the default font. Why?} And in the default font, just as expected. \stoptext %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% % Adapted MWE %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% \define[1]\mytitleformat{% \switchtobodyfont[chorus]% #1 } %\setuphead[subject,title][textcommand=\mytitleformat] %\setuphead[title][textcommand=\mytitleformat] \setuphead[subject][textcommand=\mytitleformat] % this will adapt the format for subjects, as long as titles are not changed \starttext \title{In Zapf Chancery} \subject{Apparently the default font.

Hi Hraban, Downgrading zint to 2.12.0 worked for me. Many thanks! In case someone is experiencing similar issues, I ran: brew remove zint curl https://raw.githubusercontent.com/Homebrew/homebrew-core/962d789d26c9d8f760… > zint.rb brew install zint.rb zint --version (should be 2.12.0) [follow the instructions to symlink zint to tex/texmf-osx-64/bin/lib/luametatex/zint] mtxrun --generate

Re: ConteXt commands in an rtl environment

I tested a few text editors with better RTL support and all of them show the text in the same way as TeXShop. Support for RTL in Visual Studio Code seems to be limited because the editor doesn't use the Unicode Bidi Algorithm [1]. [1] https://wiki.archlinux.org/title/Bidirectional_text#Editors Wolfgang

unprotecting when defining in Lua
by Pablo Rodriguez 29 Apr '24

29 Apr '24

Dear list, I have the following sample: \starttext \startluacode function document.test(str) context(str) end interfaces.definecommand { name = "testing", protected = false, macro = document.test, } \stopluacode \meaningfull\testing \def\test#1{#1} \meaningfull\test \stoptext Which is the right way to use "interfaces.definecommand" to get a simple command as in standard TeX? I mean, no a non \permanent or non \protected command. Many thanks for your help, Pablo
