odd behaviour of mp odd function in lmtx
by Damien Thiriet 07 Jan '21

07 Jan '21

Hi, I may have found the bug that broke my metafun file. Looks like it is connected to odd function. This snippet of code: \starttext \startMPpage path p;p:=origin--(20,20); draw p; draw p reflectedabout ((10,10),(10,-10)) withcolor red; for i=1 upto 2: if odd i: draw p yshifted 20 withcolor green; else: draw p xshifted 20 withcolor blue; fi; endfor; \stopMPpage \stoptext does not compile as I would expect (no green line drawn). I noticed such behaviour in 2020.12.30 16:45 version. I updated a few minutes ago and have the same output. I hope I didn't miss anything. Best regards, Damien Thiriet

odd seems to be broken in lmtx-metafun
by Damien Thiriet 07 Jan '21

Hi, I think I found the bug that made me send a "false positive" a few days ago. Looks like something messes up with metafun odd function. This snippet of code: \starttext \startMPpage path p;p:=origin--(20,20); draw p; draw p reflectedabout ((10,10),(10,-10)) withcolor red; for i=1 upto 2: if odd i: draw p yshifted 20 withcolor green; else: draw p xshifted 20 withcolor blue; fi; endfor; %draw (0,0)--(20,20) withcolor red; \stopMPpage \stoptext does not compile as I would expect it: no green line is drawn (but there is an output). I hope I did not miss something and won't waste your time. This appeared at least in 2020.12.30 16:45 version (I don't update often enough to give better hints) Best regards, Damien Thiriet

Problem with show command in MetaFun
by Keith McKay 07 Jan '21

07 Jan '21

In the MWE below I would expect the "show" command to print the value of p in the console output (I use Texworks), however this does not seem to be happening. I haven't used "show" in MetaFun for a while, am I implementing it correctly? Best Wishes Keith McKay %%%%%%%% MWE %%%%%%%%% \setuppapersize[A4, portrait] \starttext \startMPpage StartPage; width := PaperWidth ; height := PaperHeight ; unit := cm ; numeric p; p := 0; for q = 0 step 1 until 10: show p; p := p + 1; fill fullcircle xyscaled(3cm,4cm) shifted ((p +2)*cm, (p + 2)*cm) withcolor red ; endfor; StopPage; \stopMPpage \stoptext

Re: [NTG-context] Continued chapter numbers
by jbf 07 Jan '21

\defineresetset [jbfreset] [] [0] \setuphead [chapter] [sectionresetset=jbfreset] That does indeed work for me. I had searched everywhere on the wiki and in the manuals for something like this, based on 'reset' but could not find it. While it is clearly something you knew (and I now know!), do you know where this is mentioned in any ConTeXt documentation? Grateful for the solution! Julian

Randomize order of blocks
by Jairo A. del Rio 07 Jan '21

07 Jan '21

Hi, list. Some time ago I realized ConTeXt has "blocks" which allow one to make quizzes, exams and related with ease. However, I want to know if there's an option to randomize their order when printed. Thank you in advance. Jairo

Display reference number as Roman number
by Rik Kabel 06 Jan '21

06 Jan '21

Hello all, What I thought should be a simple conversion escapes me. I have a reference (created originally via a label defined by \definelabel) that, when referenced as *\in[label]* or *\ref[number][label]* displays a number, and that is how I normally use it. However, I want to display it in one instance as a Roman numeral. *\**Romannumerals{\in[label]}* complains that it is not being fed a number. How can I display the label number in Roman number format in this one instance? -- Rik

Continued chapter numbers
by jbf 06 Jan '21

06 Jan '21

I need chapter numbers to continue sequentially across several parts. At the moment, when Part 2 begins, it begins with Chapter 1 once more, while it should be (in continued sequence) Chapter 4. I know that I can achieve the desired result by including ownnumber=4, so: \startchapter[title={My chapter title},ownnumber=4] will do that for me. But this means I have to do it for every chapter that follows (there are 11 more!). Perhaps there is a single way to get the result I want in the preamble with \setuphead[chapter] or similar. I have searched the wiki but it is not easy to find an answer to this. Can anyone point me to where, in the wiki, I can find a simple way to ensure sequential chapter numbers? Julian

\definefontfeature and script
by Pablo Rodriguez 06 Jan '21

06 Jan '21

Hans, this sample shows an issue with script: \definefontfeature [default] [default] [script=latn] \definefontfeature [onumsmcp] [onum=yes, smcp=yes, c2sc=yes] \setupbodyfont [pagella] \starttext \feature[+][onumsmcp]\tfb abc123ABC \stoptext If script=auto, current latest (2021.01.05 10:45) works fine. If it is set to Latin (as above), I don’t get small caps. Besides the potential issue in ConTeXt, I think that "script=auto" may be safer than "script=latn". Or am I taking too much for granted? Many thanks for your help, Pablo -- http://www.ousia.tk

lmtx upload
by Hans Hagen 05 Jan '21

05 Jan '21

Hi, A new version has been uploaded. This one has: \enableexperiments[fonts.compact] for the brave to test. As a reminder, as this has been around for a while now, if you really want to stress your test, run with (top of file): \overloadmode 4 % error \overloadmode 3 % warning in order to see if you (re)define primitives, core functionality, instances and whatever can lead to conflicts. There are still some commands to be tagged (and for some the category might change) but it's a bit of a tedious job. Btw, for metafun the warnings are enabled by default (for now), but users might have noticed that already.
