ConTeXt LMTX 2024, \setupalign: Is the "Nicer justification and microtypography" list of options listed in ConTeXt Garden now obselete?
by Felix 14 Sep '24

14 Sep '24

When I try to use a combination (example = \setupalign[normal,extremestretch,verytolerant,hangingboth,fullhz,hyphenated,] ) and just normal I seem to be getting the same result when I try to load in a big paragraph. However, there is an obvious difference between me entering (just) flushleft, normal, flushright. Have those options become obsolete? how am I supposed to know? I use the latest version of LMTX

Validation of pdf/A-2a
by Thomas Meyer 14 Sep '24

14 Sep '24

Hello, I would like to use pdf/A-2a for my documents and was wondering whether the documents will stand up to validation. I used veraPDF for the validation check. Unfortunately the a-variants (pdf/A1-a and pdf/A-2a) fail. Here the Validation Information: Validation information *Rule* *Status* Specification: ISO 19005-2:2011, Clause: 6.7.3.3, Test number: 1 <https://github.com/veraPDF/veraPDF-validation-profiles/wiki/PDFA-Parts-2-an…> The logical structure of the conforming file shall be described by a structure hierarchy rooted in the StructTreeRoot entry of the document's Catalog dictionary, as described in ISO 32000-1:2008, 14.7 **Failed** 1 occurrences Hide PDDocument StructTreeRoot_size == 1 root/document[0] StructTreeRoot entry is not present in the document catalog Specification: ISO 19005-2:2011, Clause: 6.7.2.2, Test number: 1 <https://github.com/veraPDF/veraPDF-validation-profiles/wiki/PDFA-Parts-2-an…> The document catalog dictionary shall include a MarkInfo dictionary containing an entry, Marked, whose value shall be true **Failed** 1 occurrences Hide CosDocument Marked == true root MarkInfo dictionary is not present in the document catalog, or Marked entry is set to false or is not present in the MarkInfo dictionary (MarkInfo = null, Marked = null) See the (shortened) minimal example taken from the wiki below. Does anyone have any experience or advice on how to make pdf/A-2a valid?

Indentation in headings
by Kirill Davidov 14 Sep '24

14 Sep '24

Greetings, As per Russian GOST standards, numbered section headings are flush left and start with the paragraph indent. Is there a proper way to indent a section heading? The code simulates what I want visually, but it unfortunately causes the heading to poke out into the margins. That can be troublesome if the title is long enough. Example code to tinker with: \setupindenting[yes, 2.5em, first] \setuphead[section][ style=\bf, align=flushleft, distance=1em, indentnext=yes, ] \showframe \startdocument \startsection[title=Foo] \input dijkstra \stopsection \startsection[title=Very long section title that makes you question the author's writing capabilities] \input dijkstra \stopsection \setuphead[section][ style=\bf, align=flushleft, distance=1em, indentnext=yes, before=\blank[2*big]\indentation, ] \startsection[title=Foo] \input dijkstra \stopsection \startsection[title=Very long section title that makes you question the author's writing capabilities] \input dijkstra \stopsection \stopdocument

ConTeXt beginner, What should I enable within font features? And how do I see all the options possible?
by Felix 13 Sep '24

13 Sep '24

https://pastebin.com/245uwYj4 I have this setup for my fonts, called myfonts. I assume that `\definefontfeature [default] [default] [trep=yes,dlig=yes,itlc=yes]` will affect every single font that goes into my preamble (Forgive me if I seem incompetent, I am a beginner at ConTeXt) I have dlig and trep on so that works with single quotations like don't have a directional quote, and so that I get the Times New Roman ligatures via dlig and not just liga. itlc is enabled since I read some documentation and they sometimes mention enabling it is there some stuff like the extrafeatures option or anything that you would recommend i enable? might there be options for extrakerns that would be seen as something that one should enable? also, how can I see all the options available? dlig is something I discovered by accident that was not in the options list in the documentation. i use the latest version of ConTeXt LMTX on Windows

collector advice
by jbf 12 Sep '24

12 Sep '24

Using the example in the ConTexT wiki for "collectors", I have as follows, to credit the person who took the photo: \setupcaption[number=no] \definecollector[example] \setcollector [example] {\leftaligned{\externalfigure[bird.jpg][width=5cm,frame=off]}} \setcollector [example] [corner={right,bottom},location={left,top}] {\rotate[rotation=90]{\framed[frame=off]{\tfx Taken by Kathy Luck, used with permission}}} \placefigure [] [] {} {\composedcollector{example}} The pic goes beneath a poem which is left aligned, so I want the photo to be left aligned, and relatively small, hence the 5cm width. Problem is that that vertical label (Taken by...) is on the right hand side of the page, and I can't seem to adjust that with various offset attempts to bring it across to the right of the pic. How do I now get it to do so? Julian

\m vs $ for math mode
by Shiv Shankar Dayal 12 Sep '24

12 Sep '24

Hi all, I had been using $ for math mode. Then I read the new manual that \m is better for math mode. Can you please give some examples to see this in action? BTW, I have started using \m but changing all existing formulas is very tedious. -- Respect, Shiv Shankar Dayal

how do I get the correct page numbers and do the calculations with it?
by ai2472206007＠yeah.net 11 Sep '24

11 Sep '24

Thank to all who answered my questions before. As the title suggests, how do I get the correct page numbers? For example, in the example below, the first line on the 2nd page, but the page number showed is 1, In the meantime, I tried using \definepagestate, but it didn't seem to work either. What I can think of is to use citations to get the correct page number. But it seems that what is obtained is not a pure number, and it cannot do the calculations. so ,how do I get the correct page numbers and do the calculations with it? thanks. %%%%%% start example \starttext %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% %%% try page state \definepagestate[test][delay=yes] \newcount\test \let\testfloatrealpage\realpageno \def\testsavedata {\setpagestate[test][\number\test]} \def\testloaddata % precedes save ! {\global\advance\test\plusone \xdef\testfloatrealpage{\pagestaterealpage{test}{\number\test}} \ifx\testfloatrealpage\empty \glet\testfloatrealpage\realpageno \fi} \testsavedata% %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% \dorecurse{10}{% \testloaddata% \input knuth \pagereference[XX:#1] {\ssd\color[red]{\the\pageno}}% on page 2 and show page 1 {\ssd\color[red]{\the\testfloatrealpage}}%on page 2 and show page 1 {\ssd\color[red]{\ref[page][XX:#1]}}% on page 2 and show page 2 } \stoptext % stop example Muyik

Inmargin labels fail to be placed on makeup pages
by Rik Kabel 11 Sep '24

11 Sep '24

Hello all, As the subject says, labels (\definelabel) with alternative=inmargin are not placed on makeup pages. (Left and right placement works.) The following example demonstrates this. (ConTeXt ver: 2024.08.16 15:49 LMTX fmt: 2024.8.16 int: english/english) \showframe \definemakeup [epigraphs][pagestate=start] \definelabel [ipe][alternative=inmargin] \definelabel [epi][alternative=right] \starttext \epi[top]This is a numbered page.\ipe[TOP] \startmakeup[epigraphs] The thing about quotes on the internet is that you cannot confirm their validity. -- Abraham Lincoln\epi[epigraph]\ipe[EPIGRAPH] This page is numbered, but the number is not displayed. \stopmakeup Label TOP is on page \at[TOP]. Label top is on page \at[top]. Label epigraph is on page \at[epigraph]. Label EPIGRAPH is on page \at[EPIGRAPH]. \stoptext Unfortunately, enumerations cannot take the place of labels for my use case, as discussed a number of years ago <https://www.mail-archive.com/ntg-context@ntg.nl/msg86880.html>. -- Rik

Oops, I nearly forgot: You’re invited to our regular online meet-up, this upcoming Wednesday, September 11, 19:00 CEST (UTC+2) at https://lecture.senfcall.de/hen-rbr-rku-oke (same, but shorter: https://u.mtxrun.eu/ctxmtg) ConTeXt users of all levels are welcome! Looking forward to seeing you, Hraban (Same blurb as always:) [Howto] * No special software installation required; most modern browsers should work (WebRTC required). * Open the URL above, accept the privacy statement, * enter your name, * click "join" (or "start" if you’re the first), * click "with microphone", allow your browser to access it, check the audio. * Your microphone is muted if you join. Activate microphone and/or camera with the buttons at the bottom. * Minimize the default presentation with the "screen" button, bottom right. * If you’d like to share your screen or upload a file, you can make yourself the presenter: Click on your user name, change the setting, then you’ll see the "screen sharing" button beside the camera button; also there’s now "manage presentations" behind the "plus" button. Beware there is only one presenter at a time, so don’t kill someone else’s presentation. [Technical hints] * Sound is usually better if you use a headset (less noise for everyone). * Connection problems are mostly due to low bandwidth or high latency on your side, e.g. with mobile connections. * Sometimes leaving and re-entering helps. * If audio/video doesn’t work for you, you can still use the text chat. * Screen sharing needs a lot of bandwidth. * BigBlueButton documentation applies: https://bigbluebutton.org/teachers/tutorials/ [Netiquette] * Please use a name that we recognize from here. Some feel uncomfortable with anonymous lurkers. * Mute your microphone while you’re not talking. * It’s nice to show your face at least when you join. * If there are connection problems, stop camera sharing. * The room is set to “everyone’s a moderator“, I trust you...

How to use Adobe Acrobat Reader (free) as the pdf viewer when compiling file in Windows Terminal (Windows)
by Felix 10 Sep '24

10 Sep '24

I want to use Adobe Acrobat Reader (free) and I always get this message when I have my Windows Terminal, vs code and acrobat setup backend > quitting because file 'Chapter 4 Assignment.pdf' cannot be opened for writing I run into no problems with using sumatra or okular, but Adobe Acrobat free seems to have this problem. Is there a way to fix this? The way I run context on windows is by making the doc in vscode (no extension, just plain vscode), compiling in Windows Terminal and using a pdf viewer to then view stuff.
