serial letters
by Henning Hraban Ramm 11 Nov '24

11 Nov '24

How would you approach serial letters, e.g. to all members of a club? (Actually I need to send out donation receipts.) I’d like to use the letter module, since my usual letter design is using it. I can export the addresses to CSV, JSON, Lua tables or whatever or transfer them to a SQLite db. Would it make more sense to read them in Lua and combine this data with a buffer, or to write a single tex file for every letter? I know how to do the latter, but I’d like to learn a more ConTeXt-ish way. Would it make sense to use the bibliographies module?

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/

index sort order (de)
by Henning Hraban Ramm 08 Jul '24

08 Jul '24

Hi, I checked the German index sorting rules, and as far as I can tell, all of them are somewhat wrong. – de, default, or no setting (just mainlanguage de) – Duden - DIN 5007-1(:2005) - DIN 5007-2(:1996) - de-AT IMO, "Duden" is obsolete, should be the same as default; it makes no sense to have a default setting that doesn’t adhere to the official rules. If Û#m not mistaken it’s also the same as DIN 5007-1; maybe there was a difference before 2005. (DIN 5007-2 and de-AT have their uses.) The order of umlauts etc. should be ok. [ß] In tex/context/base/mkiv/sort-lan.lua, ß is replaced by s, while it should be sorted like ss in default and both DIN versions. (de-AT sorts ss after ß.) [upper-/lowercase] While casing is not mentioned in Wikipedia (https://de.wikipedia.org/wiki/Alphabetische_Sortierung) Duden „Satz und Korrektur“ says: Uppercase characters get sorted the same as lowercase (i.e. mixed), but if both appear, lowercase comes first. ATM all German settings sort lowercase behind uppercase. Generally, default method seems to be not "default" but "before". Does this make sense? If we look at the method presets, there’s none for {zm,pm,zc,zm,uc} (upper like lower, ignore diacritics – basic default for German). """ \mainlanguage[de] \setupregister[index][language=de] \starttext \index{Apfel} \index{Äpfel} \index{apfel} \index{äpfel} \index{aepfel} \index{Aepfel} \index{Ápfel} \index{ápfel} \page \completeindex \stoptext """ default order should be: aepfel Aepfel apfel Apfel äpfel Äpfel ápfel Ápfel aqua DIN 5007-2 sorts like: aepfel Aepfel äpfel Äpfel apfel Apfel ápfel Ápfel aqua de-AT sorts like: aepfel Aepfel apfel Apfel aqua äpfel Äpfel ápfel Ápfel Hraban

x mark symbol and general symbol guide
by Gerion Entrup 15 Jun '24

15 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

setuphead in connection with the command argument
by Gerion Entrup 06 Jun '24

06 Jun '24

Hi, I'm trying to adapt the format of chapters in my document and have a few questions regarding setuphead. My aim is to have the chapter (title) on a separate page with an additional intro in different text sizes for title, subtitle and the intro. I chose to use the "command=" argument in setuphead for that. However, I'm not quite sure about it's internals. Let's begin with a minimal example: ``` \define[2]\MyChapter{% #1 #2: \structureuservariable{subtitle} (\structureuservariable{intro}) } \setuphead[title, chapter][command=\MyChapter] \setupbodyfont[11pt] \starttext \startchapter[title=foo][subtitle=bar, intro={some explanation}] some text \stopchapter \stoptext ``` This produces 1.pdf. ## Font size What is the reason that that the font of the chapter is bigger? How can I reset it to normal size? This does not work at all: ``` \define[2]\MyChapter{% \setupbodyfont[11pt] #1 #2: \structureuservariable{subtitle} (\structureuservariable{intro}) } ``` However, changing to a bigger font works somehow. Is there a factor applied to the font size internally? For example: ``` \define[2]\MyChapter{% \setupbodyfont[20pt] #1 #2: \structureuservariable{subtitle} (\structureuservariable{intro}) } ``` produces 2.pdf (the chapter font is not 20pt). ## Line breaks How can I achieve line breaks? This does not work: ``` \define[2]\MyChapter{% #1 #2:\\ \structureuservariable{subtitle}\\ (\structureuservariable{intro}) } ``` (see 3.pdf) I also want to set everything except of the intro in a flushright environment but do not know how. I tried: ``` \define[2]\MyChapter{% \startalignment[flushright] #1 #2:\\ \structureuservariable{subtitle}\\ \stopalignment \structureuservariable{intro} } ``` (see 4.pdf, no change) ## Bold text I tried to get the text bold. However, `#1` and `#2` does not seem to follow this. ``` \define[2]\MyChapter{% \bold #1 #2: \structureuservariable{subtitle} (\structureuservariable{intro}) } ``` ## Makeups The best solution, I had so far, was to define a makeup, but I don't get it to work with text with mixed alignment and it does not solve the font size problem: ``` \definemakeup[chapter][align=left, top=] \define[2]\MyChapter{% \startmakeup[chapter] #1 #2:\\ \structureuservariable{subtitle}\\ \stopmakeup (\structureuservariable{intro}) } ``` (see 5.pdf) ## Framed I also have tried this but it does not bring any linebreaks: ``` \define[2]\MyChapter{% \framed[frame=off, offset=0pt]{#1\\#2:\\ \structureuservariable{subtitle}\\ (\structureuservariable{intro})} } ``` (see 6.pdf) I hope you can shed some light into setuphead with command. I search on the wiki, Stackoverflow and the manuals but didn't really find anything. Best, Gerion

Number in a circle
by Kip Warner 04 Jun '24

04 Jun '24

Hello list, I would like to typeset a number in a circle. Nothing fancy. No special colours, transforms, or complex metapost magic (which I am not familiar with). I have tried \circled{3} and \textcircled{3}, but ConTeXt does not appear to recognize these commands. Any help appreciated. -- Kip Warner OpenPGP signed/encrypted mail preferred https://www.thevertigo.com
