Regular online meet-up
by Henning Hraban Ramm 11 Apr '22

11 Apr '22

You’re invited to join next Tuesday, February 8th, 15:00 CET (UTC+1) at https://lecture.senfcall.de/hen-rbr-rku-oke ConTeXt users of all levels are welcome! Hans offered to give a Q&A session again – please announce subjects you’d like to discuss ASAP, so that he can prepare. Regarding the date: Denis, who originally suggested Tuesday afternoon, can’t take part due to other obligations. I could also offer Wednesday or Thursday. We could also change the weekday every time, but that might be confusing. I would keep the European afternoon time, since that makes participation possible for people from America and Asia. What do you think? Vote here: https://nuudel.digitalcourage.de/tB1MHH4jx6M5uwPg (Same blurb as last 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.

[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. * You can also join with a regular telephone (audio only, of course), call +49-6151-86275-22 (German landline); then you must enter a PIN that changes every time – if you need it, ask me for it via email.

Re: [NTG-context] Problems with itemize with several columns
by Xavier B. 25 Feb '22

It seems that putting \column before itemize of 'c', forces 'c' together with this content. Repeating this step produces what I want: \startexercici[exercici:operacions-amb-fraccions-2]{multiplicació i divisió} Opereu: \startitemize[a, columns, three] \item \startformula 3 \cdot \frac{5}{3} \stopformula \item \startformula \frac{3}{4} \cdot \frac{2}{5} \stopformula \column \item \startformula \frac{1}{3} \cdot \frac{3}{4} \div \frac{1}{5} \stopformula \item \startformula 5 \div \frac{7}{10} \cdot 7 \div \frac{2}{5} \stopformula \column \item \startformula \frac{1}{2} \cdot \frac{1}{2} \stopformula \item \startformula \frac{3}{2} \div \frac{2}{3} \div \frac{5}{4} \stopformula \column \item \startformula \frac{2}{3} \colon \frac{2}{5} \stopformula \item \startformula \frac{3}{4} \colon \frac{1}{2} \cdot 6 \stopformula \item \startformula \frac{2}{3} \colon \frac{3}{4} \cdot \frac{1}{2} \stopformula \stopitemize \stopexercici @fv leung said I have to replace frac for dfrac, but it mess up the following content in my book.

Item (c) will need the same amount of space, shown by the red line.

Thanks, Bruce, for clarifying this. But can we put 'c' character in the second column. So 'c' and its math content were together. The annoying thing is that the letter is in one column and its content in another.

Problems with itemize with several columns
by Xavier B. 25 Feb '22

25 Feb '22

Hi, I try to solve this, but I could not. Can you please help me. I make a math problem sheet. In "Exercici 1.2", I put a itemize with three columns, but the 'c' exercise jumps to second column. I want that a, b, c remains in the first column, d, e, f in the second and g, h, i in the third. I tried \column command but it's worse. I attached the source and generated pdf. My version of context is: context --version mtx-context | ConTeXt Process Management 1.04 mtx-context | mtx-context | main context file: /usr/share/texmf-dist/tex/context/base/mkiv/context.mkiv mtx-context | current version: 2021.03.05 19:11 mtx-context | main context file: /usr/share/texmf-dist/tex/context/base/mkxl/context.mkxl mtx-context | current version: 2021.03.05 19:11 Thanks in advance, Xavier PS: Please CCme

Cyrillic alternate form in Neacademia
by Stefan Nedeljkovic 23 Feb '22

23 Feb '22

Dear list, I'm using the typeface Neacademia Text, and I'm trying to configure it to the specifics of the Serbian language. I want to replace the usual form of the lowercase cyrillic letter BE with the traditional Serbian form. I opened the font file in Font Forge and looked up the glyph info. Here is what I tried and what failed: \startluacode fonts.handlers.otf.addfeature { name = "besub", type = "substitution", data = { ["uni0431"] = "uni0431.SRB.alt" } } \stopluacode \definefontfeature[default] [mode=node,kern=yes, liga=yes,dlig=yes, calt=yes,ss03=yes, case=yes,ccmp=yes, locl=yes,script=cyrl,language=srb, besub=yes] No luck using hex codes either: \startluacode fonts.handlers.otf.addfeature { name = "besub", type = "substitution", data = { [0x1ab] = 0x3f8 } } \stopluacode"uni0431" Interestingly the single substitutions from page 175 of the fonts manual seem to work just fine. Any help is appreciated. Sincerely, Stefan

Bibliography
by Willi Egger 22 Feb '22

Hi all, I have a rather old project which involves a bibbliography of about 60 entries. — Now I tried to use the publications environment after reading the manual. — I must say environment this is impressive! However I struggle with getting it working. 1. When using my dataset, which is encoded as a ‘bbl’ type file I get a list of publications but the entries are uncomplete. enclosed files: publist-test.tex, test-literaturliste.bbl, publist-test.pdf 2. When I use a buffer for testing, I do not get \cite reference nor a publication list: publist-buffer-test,tex Can someone advise? Kind regards Willi

Disable reuse of figures
by Aditya Mahajan 21 Feb '22

21 Feb '22

Hi, This is related to a bug report for the filter module: https://github.com/adityam/filter/issues/60 Normally, when the same figure is included twice, context only includes the figure once and refers to the included figure the second time. The option `object=no` to externalfigure is supposed to prevent that, but it doesn't work. For example, consider the following example the bug-report uses graphviz as the external program, but I have changed that to context to keep things self contained) \usemodule[filter] \defineexternalfilter [graphviz] [ filter=context --purge, output=\externalfilterbasefile.pdf, readcommand=\ReadPDF, ] \def\ReadPDF#1% {\externalfigure[#1][object=no]} \starttext Circle: \startgraphviz \startMPpage draw fullcircle scaled 1cm; \stopMPpage \stopgraphviz Square: \startgraphviz \startMPpage draw fullsquare scaled 1cm; \stopMPpage \stopgraphviz \stoptext Behind the scenes, the first \startgraphviz ... \stopgraphviz environment writes the content to an external file (\jobname-temp-graphviz.tmp), runs `context --purge \jobname-temp-graphviz.tmp`, which creates `\jobname-temp-graphviz.pdf`. The `\ReadPDF` macro then includees the file (with object=no). At the next \startgraphviz .. \stopgraphviz, the same process is repeated. The `\jobname-temp-graphviz.pdf` file is overwritten and the new file should have been included. But it is not. The output contains the first image twice. I thought that object=no should have prevented the reuse. In fact, if I compile the file with luatex, I get an error message: ! error: (pdf inclusion): file has changed '12-two-outputs-temp-graphviz.pdf' mtx-context | fatal error: return code: 256 Any idea why object=no is not working? Thanks, Aditya

footnote width in specific paragraph instance
by jbf 20 Feb '22

20 Feb '22

I need to typeset a document that contains many poetry/verse examples, and am using \defineparagraphs[mypar][n=2] for the purpose. In one specific case a footnote is required. All good except that the footnote is the width of one of those two 'columns', not the usual textarea width. Here is the current setup (the 'poem' environment is previously defined and not relevant here for my problem): \startmypar \startpoem red desert dust invades every crevice – vast deserts that we inhabit inhabit us\footnote{The ‘reddesert dust...’ is adapted from Matthew diNevop. 103.} \stoppoem \nextmypar \startpoem {\emI will lead you into the wilderness, speak fondly to you of my everlasting love my unfailing kindness} \stoppoem \stopmypar The resulting footnote: 1. The ‘red desert dust...’ verse overleaf is adapted from Matthew di Nevo p. 103 Is there a way I can get the footnote not to break after 'overleaf' and be normal textarea width instead? I did try \setupfootnotes[width=broad] but that did not help. Julian
