Hello, Happy New Year! I got into a bug in my Vim syntax highlighting version. Highlight stays in lua mode after ctxlua macro is closed. Here is a MWE, where «this should not be highlitghted as a comment indeed is. \starttext Hello! \ctxlua{context("does the parser work?")} -- this should not be highlighted as a comment \stoptext Do other Vim users come into this? Is my syntax file outdated? I am using this Vim version on OpenBSD 7.3 -stable: VIM - Vi IMproved 9.0 (2022 Jun 28, compiled Sep 6 2023 08:55:14) Included patches: 1-1876 Best regards, Damien Thiriet

Setuphead issue!
by G.C.H.M. Verhaag 09 Jan '24

09 Jan '24

Hi, I'm a bit puzzled by the mkiv /setuphead/ command of ConTeXt! The space *before* and *after* the /subject/ command can usually be set by the *before* and *after* arguments of the /setuphead/ command. Now I'd like to have _no vertical space_ before and after the header. I've tried just that by setting either *before=* and *after=* and *before=\blank[none]* and *after=\blank[none]*. But none of these seem to work. Any idea? Gerard --

Dear List, Is this the right way? I want to use linked bibliography numbers, linked Chapter, section subsection, linked margin numbers, in the text. \setupinteraction[state=start] \starttext Der Wert von \m{y = f(x)} ist unabhängig von der Wahl\par von \m{x\doubleprime} ist gleichbedeutend mit \m{∃y : ∀x : f(x) = y} \par (Beutelspacher [\hyphenatedurl {10},S.54]). \stoptext Many thanks Uschi

MetaFun path joiners && and &&&& do not like single point paths
by Gavin 08 Jan '24

08 Jan '24

Hi MetaFun fans, Following a suggestion of Hans, I experimented with && and &&& and &&&& for joining paths in MetaFun. The joiner &&& produces one long path, but && and &&&& seem to produce a disconnected path which includes all the original paths. However, if one of the paths is a single point, then it connects it. MWE below. I spotted this on my globes module, where we saw an extra line appear for a very specific orientation of the globe. I guessed that this orientation had an island right on the horizon, so that only one boundary point was visible, creating a singe point path for that island. I should probably fix my module so it doesn’t do that. However, it might be nice to have && and &&&& deal with this situation gracefully. Gavin \startMPpage path p[], q ; p1 = fullcircle scaled 3cm ; p2 = fullcircle scaled 2cm shifted (3cm,0) ; p3 = (3cm,2cm) ; q = for i = 1 upto 3 : p[i] && endfor cycle ; draw p1 withpen pencircle scaled 2pt withcolor .7 ; draw p2 withpen pencircle scaled 2pt withcolor .7 ; draw p3 withpen pencircle scaled 2pt withcolor .7 ; draw q withcolor red ; eofill q withcolor 0.9 ; draw fullcircle scaled 6cm shifted (1.25cm,0) ; \stopMPpage

Hi, With the build farm still down I now use an alternative build, that is, I run a compile script on s bunch of machines and hope for the best. In the process I decided to drop 32 bit installers (users can generate bins themselves if needed). I also drop bsd version and just use the latest. For OSX I use a retired macbook air that Hans vd Meer sent me that has an old operating system but new enough so that its xcode can make intel and arm binaries. The linux binaries have teh problem that they depend on glibc versions and I'm assuming a reasonable up to date system so I use opensuse leap (which is not even that new with it comes to glibc but we use it on servers here). texmf-win64 : laptop (linux subsystem on windows) texmf-windows-arm64 : laptop (native visual studio) texmf-linux-64 : linux-opensuse-leap (latest leap 15) texmf-linux-aarch64 : raspberrypi (latest debian) texmf-linuxmusl-64 : linux-alpine-64 (whatever) texmf-osx-64 : airbook/118/hvdm (older xcode) texmf-osx-arm64 : airbook/118/hvdm (older xcode) texmf-freebsd-amd64 : openbsd-amd64-14 (latest) texmf-openbsd-amd64 : openbsd-amd64-74 (latest) If your platform doesn't work you can download the texmf.zip, context-texmf.zip and installation.pdf and start from there: create the tree, compile from source, move the binaries and it should just work. I have no clue if the uploaded files are working but let's see ...

multipage metapost output from ConTeXt
by Emanuel Han 06 Jan '24

06 Jan '24

How can I achieve multipage metapost output from ConTeXt? The result should be a multipage pdf. It contains just a metapost graphic per page. The graphic has always the same bounding box and evolves from page to page: Some elements to be drawn are added, and some others would ideally also be removed, while keeping elements which has already been drawn on previous pages. I can manage when it is not possible to remove elements (in that case I'll just cover them with a covering element). I saw that it is possible to achieve my goal with standalone metapost, as described here: https://tex.stackexchange.com/questions/471662/mptopdf-is-multipage-output-… But I'll need to achieve this with Metapost inside ConTeXt because I use labels in Metapost which print text in Japanese, Korean , Arabic and Roman script: Thanks to ConTeXt, I can define appropriate fonts for each script. All this works already in my working example. The only unsolved problem is to ship out multiple pages. For the minimal working example, I didn't remove the font defining part, because having 4 different fonts is a condition of my use case. The graphic on the other hand is some simple dummy nonsense graphic not from my project. The graphic is in the provided example drawn as a summing up of layered drawing steps (6 steps, to be precise), so no removing is implemented here (because I don't know how that would be done). If each of the figures 1 to 6 of my mwe can be put alone on a page, I'd be already very happy. Now, they're put on top of each other all on the same single page, also on top of figure 0. The desired multipage pdf will be used in presentation mode of a pdf viewer and skipped forward and backward from page to page (that is from drawing step to drawing step). mwe: \enableregime[utf] % enable unicoded input \definefontfamily [RomanFont] [rm] [calluna] \definefontfamily [KoreanFont] [rm] [applemyungjo] \definefontfamily [JapaneseFont] [rm] [hannotatesc] \definefontfeature [fea] [mode=node,language=dflt,script=arab, init=yes, medi=yes, fina=yes, isol=yes, calt=yes, rlig=yes, tlig=yes, trep=yes, curs=yes, kern=yes, mark=yes ] \starttypescript [serif] [notonaskharabic] \definefontsynonym [notonaskharabic-Light] [name:notonaskharabic] [features=fea] \definefontsynonym [notonaskharabic-Bold] [name:notonaskharabic] [features=fea] \definefontsynonym [notonaskharabic-Italic] [name:notonaskharabic] [features=fea] \definefontsynonym [notonaskharabic-Bold-Italic] [name:notonaskharabic] [features=fea] \stoptypescript \starttypescript [serif] [notonaskharabic] \usetypescript[serif][fallback] \definefontsynonym [Serif] [notonaskharabic-Light] [features=fea] \definefontsynonym [SerifItalic] [notonaskharabic-Italic] [features=fea] \definefontsynonym [SerifBold] [notonaskharabic-Bold] [features=fea] \definefontsynonym [SerifBoldItalic] [notonaskharabic-Bold-Italic] [features=fea] \stoptypescript \starttypescript [notonaskharabic] \definetypeface [notonaskharabic] [rm] [serif] [notonaskharabic] [default] \stoptypescript \usetypescript[notonaskharabic] \setupbodyfont [RomanFont] \starttext \startMPcode picture p[]; path bb; %bounding box z0 = (0,0); z1 = (60,40); z2 = (40,90); z3 = (10,70); z4 = (30,50); z5 = (90,70); z6 = (-10,70); path A; A = z0..z1..z2..z3..z4 ; pair AStartPoint; AStartPoint = point 0 of A; pair AEndPoint; AEndPoint = point 4 of A; path B; B = z5..z6; pair BStartPoint; BStartPoint = point 0 of B; pair BEndPoint; BEndPoint = point 1 of B; path C; C = AStartPoint..AEndPoint; % drawing steps: p1:=image( draw A withcolor red; ); p2:=image( label(textext("\JapaneseFont 日本語"), AEndPoint); ); p3:=image( label(textext("\notonaskharabic \textdir TRT دانگ") scaled 1.2, AStartPoint); ); p4:=image( label(textext("\KoreanFont 한국어"), BStartPoint); ); p5:=image( label(textext("\RomanFont bāng"), BEndPoint); draw C withcolor green; ); p6:=image( draw B withcolor blue; ); beginfig(0); %% the whole picture for the common bbox for k=1 upto 6: draw p[k]; endfor bb:=bbox(currentpicture); endfig; for $=1 upto 6: beginfig($); for k=1 upto $: draw p[k]; endfor setbounds currentpicture to bb; endfig; endfor \stopMPcode \stoptext
