by Bruce Horrocks 18 Jan '23

18 Jan '23

ConTeXt ver: 2023.01.04 The following MWE won't compile because of the \dummycommand line even though it is a comment. Not sure whether it's a minor bug or an unavoidable aspect of allowing embedded Lua. \startluacode -- \dummycommand \stopluacode \starttext Hello \stoptext — Bruce Horrocks Hampshire, UK

question about multimedia renderings
by Pablo Rodriguez 16 Jan '23

16 Jan '23

Dear list, I’m planning to add an explanation about multimedia inclusion to the wiki, but first I wanted to discuss an issue I have found. I have the following sample (adapted from scrn-wid.mklx): \setupinteraction[state=start] \starttext \null\page \definerenderingwindow[myrenderingwindow] [width=\textwidth, height=\textwidth, %openpageaction=StartCurrentRendering, %closepageaction=StopCurrentRendering, openpageaction=StartRendering{\currentrendering}, closepageaction=StopRendering{\currentrendering}, framecolor=red] \startTEXpage[offset=1em, pagestate=start] \userendering[key-name][video/mp4][video.mp4] [embed=yes, auto, ] \placerenderingwindow[myrenderingwindow][key-name] \stopTEXpage \null\page \stoptext \userendering[][][auto] would enable automatic play or stop when the page with the rendering is reached or left (respectively). I cannot get it working. Neither do work the commented lines in \definerenderingwindow. Inspecting the PDF code, the screen annotation only gets an additional actions dictionary (https://opensource.adobe.com/dc-acrobat-sdk-docs/standards/pdfstandards/pdf…) with /PO and /PC entries, when open and close page actions are set to StartRendering{\currentrendering} and StopRendering{\currentrendering}. Just for reference, this is the screen annotation object with the additional actions dictionary: 13 0 obj << /Type /Annot /A << /AN 13 0 R /OP 0 /R 12 0 R /S /Rendition >> /AA << /PC << /AN 13 0 R /OP 1 /R 12 0 R /S /Rendition >> /PO << /AN 13 0 R /OP 0 /R 12 0 R /S /Rendition >> >> /Border [ 0 0 0 ] /P 14 0 R /Subtype /Screen /T <FEFF006B00650079002D006E0061006D0065> /Rect [ 12.353668 12.353668 437.54664 437.54664 ] >> endobj And this is what I get with \userendering[][][auto]: 13 0 obj << /Type /Annot /A << /AN 13 0 R /OP 0 /R 12 0 R /S /Rendition >> /Border [ 0 0 0 ] /P 14 0 R /Subtype /Screen /T <FEFF006B00650079002D006E0061006D0065> /Rect [ 12.353668 12.353668 437.54664 437.54664 ] >> endobj Could anyone be so kind to confirm the issue? Many thanks for your help, Pablo

Is the Society of Biblical Literature (SBL) style files for ConTeXt incompatible with \setupinteraction[state=start]?
by Joel 15 Jan '23

15 Jan '23

When I am using the SBL ConTeXt files for citations, if I add a line `\setupinteraction[state=start` my code starts complaining: Undefined control sequence \currentbtxloctext <macro> \16>:btx:sbl:cite:inline #1->\fastsetup {\s!btx :\s!cite :concat}\fastsetup {btx:sbl:cite:lefttext}\begingroup \letbtxparameter {punct}\empty \def \currentbtxcitealternative {inline}\def \currentbtxcategory {\btxfield {category}}\def \currentbtxloctext {\btxparameter {loctex <macro> \normalexpanded \Word {\fastsetup {btx:sbl:cite:inline} }\doif {\btxparameter {righttext}}{\empty } {\btxperiod } <macro> \strc_constructions_register_yes ... Is this package incompatible with interaction? --Joel

Why does \doifsomething think there is content?
by Joel 15 Jan '23

15 Jan '23

I am creating a book that presents readers with a list of recommended materials. If materials are listed, then its displayed under the \subject{Materials} heading in a simple itemized list. I'm using \doifsomething{} to check if any items are listed. The problem I'm having is, when fed a blank macro, `\define\needsoven{}` it thinks there is content, so it displays the "Materials" heading, but an empty list. I have a custom macro that determins "if oven is needed" independent of these other items. So I need `\define\needsoven{}` to be regarded as nothing. How can I get \doifsomething{} to think \define\needsoven{} is an empty value? --Joel My minimal working example is below: \define\needsoven{} \define[1]\materialsneeded{% \doifsomething{#1}{ \subject{Materials} \startitemize #1 \stopitemize } } \starttext \chapter{Recipe 1} \materialsneeded{\needsoven} \subject{Instructions} Spread peanut butter on sandwich. \chapter{Recipe 2} \materialsneeded{\item pizza cutter \item stove} \subject{Instructions} Preheat oven to 450 degrees F. \stoptext

by Willi Egger 12 Jan '23

Good morning! Last night I updated LMTX on my Raspberry Pi4. — After this action it appeared, that I could no-more compile tex-files: error no format found. I tried to generate a format manually., however this did not work out. In the log-file the following error is placed: …/anch-pgr.lmt:901: unexpected symbol near ‘0” ... error loading file: anch-pgr.lmt (aborting). Kind regards Willi

binaries in latest
by Pablo Rodriguez 12 Jan '23

12 Jan '23

Dear list, as already reported in another thread, bimaries (for Linux64) weren’t updated with current latest (2023.01.04 11:35), Just in case it might help others (and to fix the issue), deleting the file tex/texmf-linux-64.tma allows the download of newer binaries (although the name for your platform should be different in other OS). Just in case it might help, Pablo

regular online meet-up
by Henning Hraban Ramm 11 Jan '23

11 Jan '23

You’re invited to join on Wednesday, January 11th, 15:00 CET (UTC+1) at https://lecture.senfcall.de/hen-rbr-rku-oke (same, but shorter: https://v34h.de/ctxmtg) ConTeXt users of all levels are welcome! Next meeting will be on February 8th. (Same blurb as every time:) [Howto] * No special software installation required; most modern browsers should work (WebRTC required). * Open the above URL, 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. * 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... See you, Hraban
