Hi all, This is a reminder that the registration for the upcoming ConTeXt meeting in Sibrina, Czech Republic is still open. The meeting will take place from Sept 10 to Sept 16. You can go to https://meeting.contextgarden.net for more information. You will also find the registration form there. You can (of course) attend in person, but registration for online only attendance is also possible! We hope to see you next month! NOTE: There have recently been problems with the delivery of the filled-in registration form to the organisers. If you have registered sometime *in the last month* but have not heard from Jano or me yet, please re-register (the form emailer is fixed) or at least drop us a message! Best wishes, Taco

your opinion about list structures
by Henning Hraban Ramm 22 Aug '23

22 Aug '23

Hi, this is about my ConTeXt book again… [ToC] At the moment, my table of contents has chapters and sections and is 8 pages long. I would probably hardly use it. Maybe it would be better to show only chapters (29 content + 12 appendix = 2 pages) and include a list of sections after the chapter title (or not at all). [Registers] I split between command and topic index (9 pages each), because I find it annoying to have the commands between the topics. I also include the topics that are mentioned in titles in the index, because I hate it if I must look in two places. (Otherwise I wouldn’t think about omitting the sections from the ToC.) At the moment there‘s also an index of todo items, but that will disappear before print. [Glossary] There’s a short dictionary of technical terms in the appendix (8.5 p.). Each lemma is also included in the index. Should I add a list of abbreviations? (TDS, TEI, OCG, RAL, PDF, SVG…?) They’re in the index and explained where they matter – I don’t think the meaning of many abbreviations like file types is important. [Other lists] Should I include a list of colors, like the output of \showcolor[crayola]? (I think it would only bloat the book, and everyone can create the list themselves.) I have lists of supported languages (should get checked), fonts in the distribution and all math fonts, because these are not easily reproducible (AFAIK). So, what do you think, and how do you like to work with technical books? What kind of information (about ConTeXt or documents/printing in general) do you find hard to find? Hraban

Equivalent of the \cancel command with conTeXt
by Fabrice Couvreur 22 Aug '23

22 Aug '23

Hi, In an algebraic expression, it is sometimes interesting to cross out terms. With LaTeX, there is the \cancel command from the package cancel. Is there an equivalent with conTeXt ? Thanks Fabrice

Nested itemize
by Alexandre Christe 22 Aug '23

22 Aug '23

Dear all, I'm struggling to setup a nested itemize with no blank line and several columns. What I mean is something like 1. a) bla c) bla b) bla d) bla The following MWE is my starting point \starttext \startitemize[n] \item \blank[-line] \startitemize[a,horizontal,two] [margin=2cm] \item First \item Second \item Third \item Fourth \stopitemize \item \blank[-line] \startitemize[a,horizontal,columns,two] \item First \item Second \item Third \item Fourth \stopitemize \stopitemize \stoptext Thanks in advance

Disable continued captions for table parts
by Alexey Kryukov 22 Aug '23

22 Aug '23

Dear list, probably a stupid question, but is it possible to have a table splitted across pages without adding labels to all subsequent table parts except the first one? In my book I have captions above tables (\setupcaption[table][location=top]), so they are expected to behave like normal heading. With this type of formatting any "continued" marks would look weird. -- Regards, Alexey Kryukov <anagnost at yandex dot ru> Moscow State University Faculty of History

hyphenation inside quotation
by Thomas A. Schmitz 22 Aug '23

22 Aug '23

Hi, is this a limitation or a bug? Text inside \quotation{} is not hyphenated. It appears to be like this for a couple of versions, but I'm not sure if it has always been the case. Silly example to test: \mainlanguage [de] \setuppapersize [A6] \setupbodyfont [14pt] \starttext „Originalgenie“ „Originalgenie“ „Originalgenie“ \quotation{Originalgenie} \quotation{Originalgenie} \quotation{Originalgenie} \stoptext All best Thomas

XML processing beginner's question
by Michael Löscher 22 Aug '23

22 Aug '23

Hello list, having the xml data at the bottom, I would like to process it so that the result is like this: --- What it is (e.g. bold formatted) date: 2023-08-01 (italic) Description (small font size) Another text (small font size) hd1 - Header 1 § 1 First (A first short description) AAAAAAAAAA BBBBBBBBBB § 2 Second (A second short description) CCCCCCCCCC DDDDDDDDDD § 3 Third (A third short description) EEEEEEEEEE FFFFFFFFFF --- How can I process the <element>s differently? The first element contains a <date> tag and so it differs from the other ones. The second element's <name> tag contains the word "Header" which makes it different again. The other elements contain a <shortdescription> tag that they all have in common. What could be the appropriate xml setups to generate the above output? Michael --- xml data: \startbuffer[xmlcontent] <?xml version="1.0" encoding="UTF-8" ?> <document> <element> <mdata> <name>What it is</name> <date>2023-08-01</date> </mdata> <tdata> <content> Description Another text </content> </tdata> </element> <element> <mdata> <num>hd1</num> <name>Header 1</name> </mdata> <tdata> <content> Text of Header 1 </content> </tdata> </element> <element> <mdata> <num>1</num> <name>First</name> <shortdescription>A first short description</shortdescription> </mdata> <tdata> <content> AAAAAAAAAA BBBBBBBBBB </content> </tdata> </element> <element> <mdata> <num>2</num> <name>Second</name> <shortdescription>A second short description</shortdescription> </mdata> <tdata> <content> CCCCCCCCCC DDDDDDDDDD </content> </tdata> </element> <element> <mdata> <num>3</num> <name>Third</name> <shortdescription>A third short description</shortdescription> </mdata> <tdata> <content> EEEEEEEEEE FFFFFFFFFF </content> </tdata> </element> </document> \stopbuffer

Low res output possible?

Hi Julian, I had the same question a couple of days ago and I found a thread on the mailing list, which I'm reposting here.
