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

new uplaod
by Hans Hagen 17 Apr '23

17 Apr '23

Hi, I uploaded a new lmtx. Again some updated math of which details will be revealed later. Apart from some details we added suport for fourier notations. There are no high level definitions yet as we have to invent names but this is how it works (private unicode slots might change): \setupbodyfont[pagella] \starttext \setupmathdelimited [topoffset=.2\exheight] \definemathdelimited [fourier] [rule=no, left=\zerocount, right="FE944] \definemathdelimited [courier] [rule=no, left=\zerocount, right="FE946] \definemathdelimited [xourier] [rule=no, left=\zerocount, right="FE948] $ \fourier{(z+1)} $ $ \fourier{(z+1)} + \sqrt[2]{1}$ $ \fourier{(z+1)} + \courier{(z+1)} + \xourier{(z+1)} $ $ \fourier{\left(z+\frac12\right)} + \courier{\left(z+\frac12\right)} + \xourier{\left(z+\frac12\right)} $ $ \autofences \fourier{(z+\frac12)} + \courier{(z+\frac12)} + \xourier{(z+\frac12)} $ $ \widehat{x^2 + 2x + 2} $ \stoptext This example also shows a new \autofences feature and widehats (widetilde and widecheck also work that way) that overcome limitations in fonts, so \def\CrappyHack#1{\im{#1{a} + #1{a+b} + #1{a+b+c} + #1{a+b+c+d} + #1{a+b+c+d+e} + #1{a+b+c+d+e+f}}\par} \CrappyHack\widehat \CrappyHack\widetilde \CrappyHack\wideacute \CrappyHack\widecheck will work. For thise in finance we now have $ \annuity{x + 1} + \lannuity{x + 1} + \rannuity{x + 1} + \lrannuity{x + 1} $ these are basically radicals (like sqrt) with two sided symbols.

Adding support for German language to the Words conversion
by Marcus Christopher Ludl 31 Dec '22

31 Dec '22

Hello all, this is my first contribution to this mailing list. 😄 Recently, when I posted a question on StackExchange.com regarding adding support for another language (German) to the "Words" conversion in ConTeXt (see here: https://tex.stackexchange.com/questions/657534/how-to-add-support-for-anoth…), @mickep suggested that I post the patched file (core-con.lua) to the mailing list, once I have it finished, so that it can be added for all to use. So, now that I'm confident my code works well, I would like to do just that. 😄 How should I proceed? Should I just send the file including my new code as an attachement to the mailing list? Or would it be preferrable to paste only the new parts of the code inline into an e-mail? Is that even the correct mailing list or would it be better to send this to dev-context(a)ntg.nl? Best, Marcus

regular online meet-up
by Henning Hraban Ramm 12 Dec '22

12 Dec '22

You’re invited to join on Wednesday, November 9th, 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 December 14th. (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

Convertnumber with \ref[number] fails in MkIV, works in LMTX
by Rik Kabel 06 Dec '22

06 Dec '22

Hello list, The following fails with ConTeXt ver: 2021.10.24 21:45 MKIV but works with the companion LMTX. The error message is:tex error > tex error on line 6 in file G:/TestConTeXt/convert.tex: ! Incompatible glue units , pointing to the second \convertnumber line. \definelabel[XX]%[text=,before=,after=,alternative=inright] \startTEXpage[offset=2em] abc\XX[xx]\par \ref[number][xx] · \convertnumber{r}{1} · \convertnumber{R}{\ref[number][xx]} \stopTEXpage In this case I am trying to display with roman numerals the number generated in the label created through \definelabel. Suggestions welcomed. -- Rik

filling buffers in cld documents
by damien＠thiriet.web4me.fr 27 Nov '22

27 Nov '22

Hi, I am used to giving very extensive feedbacks to my pupils. These are buffers with xtables flushing lua vectors. Here is their basic structures: * an environment that stores xtables. Turned into MWE, look like: \startenvironment env_corrige.mkiv \startluacode userdata = userdata or {} function userdata.Critere (commentaire,note,notemax) context.startxcell {"width=11cm","height=2.75cm"} context(Eleve[commentaire]) context.stopxcell () context.startxcell {"width=1.5cm","align=flushright"} context(Eleve[note]) context("/") context(notemax) context.stopxcell () end \stopluacode \startbuffer [grille] \startxtable \startxrow \startxcell \ctxlua {userdata.Critere ("structure","NoteStructure",2)} \stopxcell \stopxrow \stopxtable \stopbuffer \stopenvironment * The main file is divided in subjects, each one of them being the feedback to one pupil. In a MWE fashion \useenvironment [env_corrige] \starttext \startsubject[title={Astérix}] \startluacode Eleve = { structure = "analyse très fine", NoteStructure = 2, } \stopluacode \getbuffer [grille] \stopsubject \startsubject[title={Obélix}] Eleve = { structure = "le détail doit être travaillé. Pensez à la finesse de vos menhirs…" NoteStructure = 1, } \stopsubject \getbuffer [grille] \stoptext Since whatever I fill in those files is written inside luacode environment, I tried to switch to cld documents. Here is my main file in cld version context.useenvironment({"env_corrige"}) context.starttext() context.startsubject({title="Asterix"}) Eleve = { structure = "analyse très fine", NoteStructure = 2, } context.getbuffer({"ExoCorrection"}) context.stopsubsubject() context.startsubject({title="Obélix"}) Eleve = { structure = "le détail doit être travaillé. Pensez à la finesse de vos menhirs…" NoteStructure = 1, } context.getbuffer({"ExoCorrection"}) context.stopsubsubject() context.stoptext() The troubles is that buffers are filled with the last version of Eleve table. I guess this is because the whole file is parsed and then filled in buffers. My understanding of the cld manuel is that context.tobuffer() and context.direct() should be used, but couldn't figure out how. Tried several times, also with context.step but all failed. I think I didn't properly understand the "temp" and str of context.tobuffer description in manual. What changes should I introduce to my cld files? Best regards, Damien Thiriet

Why are my captions overlapping next text in combinations?
by Joel 26 Nov '22

26 Nov '22

I have some combinations used throughout my document like this: \starttext \startcombination[4*2] {% \framed[width=.25\textwidth, height=.25\textwidth]{}% }{% \strut word \\ \thinrule\hairline\hairline% }% \stopcombination \input knuth \stoptext This makes a box, then displays a word underneath, and then some blank lines. The problem I'm having is many times the caption text is covering up whatever appears after. In this minimal example, I tried showing the problem, but somehow this is rendering find, not covering the \input knuth text. Also, if I add more more items to the combination, the second row appears above the first row! My document is rather complex, so I couldn't find a way to simplify it enough to get a minimal example to reveal the problem that is appearing. Any ideas what might be causing the caption text to overlap and cover whatever appears after it? --Joel
