serial letters
by Henning Hraban Ramm 11 Nov '24

11 Nov '24

How would you approach serial letters, e.g. to all members of a club? (Actually I need to send out donation receipts.) I’d like to use the letter module, since my usual letter design is using it. I can export the addresses to CSV, JSON, Lua tables or whatever or transfer them to a SQLite db. Would it make more sense to read them in Lua and combine this data with a buffer, or to write a single tex file for every letter? I know how to do the latter, but I’d like to learn a more ConTeXt-ish way. Would it make sense to use the bibliographies module?

Hi, Please find attached a new version of the module, with some ideas from Marco. Later, I'll upload it to modules.contextgarden.net. Here a usage example: \usemodule[downsample] \setupexternalfigures[ location=default, % find hacker.jpg and mill.png cache=/tmp, % where to put the low resolution images resolution=50, % resolution in DPI conversion=downsample.pdf] % use this module \starttext \externalfigure[hacker][width=0.4\textwidth] \setupexternalfigures[resolution=20] \externalfigure[mill][width=4in, height=3in] \setupexternalfigures[resolution=200] \externalfigure[mill][width=4in, height=3in] \stoptext Hans, it would be nice, to apply this patch, to trigger new conversion, when figure dimensions change: --- grph-inc.lua~ 2019-02-14 17:04:12.000000000 +0100 +++ grph-inc.lua 2019-02-17 08:45:38.129971581 +0100 @@ -864,6 +864,14 @@ newbase = prefix .. newbase end local hash = "" + local width = figures.current().request.width + local height = figures.current().request.height + if width then + hash = hash ..

x mark symbol and general symbol guide
by Gerion Entrup 15 Jun '24

15 Jun '24

Hi, I recently tried to typeset a table with checkmarks and x marks. \checkmark exists but is there a predefined x mark symbol (\xmark does not work)? In general: For LaTeX there exists the very helpful comprehensive LaTeX symbol list [1]. Is there a similar documentation for ConTeXt somewhere? Best, Gerion [1] https://www.ctan.org/pkg/comprehensive

textbackground spacing offset
by Marco Patzer 31 Jan '24

31 Jan '24

Hi! I'm having problems getting the textbackground spacing offset to work. Example: \setupframedtext [offset=overlay, width=max, depthcorrection=off] \setuptextbackground [location=paragraph, %% offset=overlay, %% does nothing %% backgroundoffset=overlay, %% does nothing %% depthcorrection=off, %% does nothing %% topoffset=3mm, %% works, but only for positive values background=, frame=on] \starttext \startframedtext \framed{Foo} \stopframedtext \starttextbackground \framed{Foo} \stoptextbackground \stoptext How do it get the same spacing as in the framedtext case? The textbackground has a small gap between the inner and outer frame at the top and a larger gab at the bottom. I'm not concerned with horizontal spacing here. Marco LMTX 2023.09.04 19:15

Status of Asymptote
by Alexandre Christe 11 Jan '24

11 Jan '24

Dear all, I'd like to know what is the status of Asymptote in Context. To my knowledge, metapost/metafun only support 2D (except with the additional libraries from Roegel, which would have to be cleaned up a bit). Otherwise, what shall be used for 3D drawings in Context? TikZ? Something else? Thanks in advance. Alex

MetaFun path joiners && and &&&& do not like single point paths
by Gavin 09 Jan '24

09 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

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

Equivalent for hdots and hdotsfor
by Shiv Shankar Dayal 30 Dec '23

30 Dec '23

In LaTeX, I can use \hdots for horizontal dots and \hdotsfor{n} to fill for several columns in a determinant. But these do not work in ConTeXt. What is the equivalent for these in ConTeXt? -- Respect, Shiv Shankar Dayal
