Quickly invoke a self-defined index sorting file?
by autumnus 12 Jan '25

12 Jan '25

hi, I defined an index file for sorting Chinese. (a bit large with almost 4MB) https://github.com/Soanguy/ConTeXt-Chinese-Example/blob/master/sorting/sort… But I have to pre-reference this file with input every time to enable it. How do I fuse these files with my local context system and use setup to enable it directly. I want directly use %%% \setupregister[index][n=4,language=cn-alpha,] %%% instead of %%%% \input sort-alpha.lua \setupregister[index][ n=4, language={cn-alpha},] %%% In addition to this, I found that the following notification appeared on the tex terminal, probably because there are too many characters in the index file (tens of thousands of characters). Can I avoid this notification? tex memory > bumping category 'token' succeeded, details: all=16000000 | ext=0 | ini=568315 | itm=8 | max=10000000 | mem=2000000 | min=2000000 | ptr=1999080 | set=10000000 | stp=1000000 | top=2000000 tex memory > bumping category 'token' succeeded, details: all=24000000 | ext=0 | ini=568315 | itm=8 | max=10000000 | mem=3000000 | min=2000000 | ptr=2999080 | set=10000000 | stp=1000000 | top=3000000 tex memory > bumping category 'token' succeeded, details: all=32000000 | ext=0 | ini=568315 | itm=8 | max=10000000 | mem=4000000 | min=2000000 | ptr=3999080 | set=10000000 | stp=1000000 | top=4000000 tex memory > bumping category 'token' succeeded, details: all=40000000 | ext=0 | ini=568315 | itm=8 | max=10000000 | mem=5000000 | min=2000000 | ptr=4999080 | set=10000000 | stp=1000000 | top=5000000 tex memory > bumping category 'token' succeeded, details: all=48000000 | ext=0 | ini=568315 | itm=8 | max=10000000 | mem=6000000 | min=2000000 | ptr=5999080 | set=10000000 | stp=1000000 | top=6000000 tex memory > bumping category 'token' succeeded, details: all=56000000 | ext=0 | ini=568315 | itm=8 | max=10000000 | mem=7000000 | min=2000000 | ptr=6999080 | set=10000000 | stp=1000000 | top=7000000 autumnus

tree-sitter-context
by Henning Hraban Ramm 12 Jan '25

12 Jan '25

Hi Paul, I tried again to get your code running for me. If I replace tree-sitter-context.pc by tree-sitter.json (attached), then the tree-sitter CLI recognizes the parser. The npm module (to be called as "npx tree-sitter") doesn’t care about the .pc file, but the cli package binary seems to expect a directory by that name. Now I can call the parser with a .tex file, and the process hogs 99% CPU and all RAM (>20GB) quickly. I needed several attempts to even kill it. That doesn’t look right. Hraban

Lua question - table.save, table.load
by Jeong Dal 12 Jan '25

12 Jan '25

Dear all, I save a table “tfList” using table.save in Lua: \startluacode ... table.save(“tempList.lua”,tfList) ... \stopluacode And I call it in MetaFun using a method explained in the MetaFun book. \startMPcode lua("MP = { } MP.data = table.load('tempList.lua')") ; … \stopMPcode However, I found that whenever I save “tfList”, table contents are appended to the file “tempList.lua” at the end which cause a trouble. I want the tempList.lua contains the new table only. I search the method to do that, but I can’t find it. The only way is to change the file name each time which is not good to make a macro. Is there a way to clear the contents in the tempList.lua before I save another table? Thank you for reading. Best regards, Dalyoung

JPEG 2000 extensions
by Jim 11 Jan '25

11 Jan '25

Hi, in .../tex/texmf-context/tex/context/base/mkiv/grph-inc.lua I see (at line 333) ["jp2"] = { list = { "jp2" } }, That is (AIUI) the proper extension for JPEG2000 (Part 1) images. The JPEG2000 (Part 2) images I looked at have the same magic bytes as listed in line 349 of that file. AIUI, JPEG2000 (Part 2) images should have the extension .jpx. Is it possible to change line 333 to read ["jp2"] = { list = { "jp2", "jpx" } }, ? (I hope this is the only change needed.) I may be the only (vocal) person using .JPX files right now, but in the years to come, who knows how many people will use it? Thanks. Jim P.S. I know that I can use \definegraphictypesynonym [jpx] [jp2] but in the interest of helping others who may run into this issue in the future, ...

Functional shading with MetaPost / MetaFun
by Florent Michel 10 Jan '25

10 Jan '25

Hi, I was trying to see if I could use MetaFun / MetaPost as my main tool for generating figures. I really like its close integration with ConTeXt, speed, and expressivity making it, even for a beginner like me, a pleasure to work with. One difficulty I encountered is for generating 2D functional shadings. For instance, I am not sure what is the best way to reproduce the following pgfplots picture in MetaPost: ____________________________________________________________ \usemodule[pgfplots] \pgfplotsset{width=10cm,compat=1.18} \usepgfplotslibrary{patchplots} \starttext \startTEXpage \starttikzpicture \startaxis[ hide axis=true, axis lines=none,hide axis, enlargelimits=false, scale only axis, clip bounding box=upper bound, clip=true, ] \addplot[ patch, shader=interp, mesh/color input=explicit, data cs=polar, ] coordinates { (90,4) [color=red] (210,4) [color=green] (-30,4) [color=blue] }; \stopaxis \stoptikzpicture \stopTEXpage \stoptext ____________________________________________________________ One idea is to draw a sequence of triangles, each with a linear gradient: ____________________________________________________________ \startMPpage def LinearIntTriangle(expr pa, pb, pc, cola, colb, colc, n_iter) = for i = n_iter step -1 until 1 : path p; x := i / n_iter; y := (i - 0.5) / n_iter; p := pa -- (pa + x * (pb - pa)) -- (pa + x * (pc - pa)) -- cycle; sh := define_linear_shade(pa + y * (pb - pa), pa + y * (pc - pa), (1 - y) * cola + y * colb, (1 - y) * cola + y * colc); fill p withshade sh; endfor enddef; color cola, colb, colc; cola := (0,1,0); colb := (1,0,0); colc := (0,0,1); LinearIntTriangle((0,0), (50,50*(3**0.5)), (100,0), cola, colb, colc, 30); \stopMPpage ____________________________________________________________ or to use a slight variation (decomposing the triangle in three so that the color is ‘right’) along each edge: ____________________________________________________________ \startMPpage def LinearIntTriangleB(expr pa, pb, pc, cola, colb, colc, n_iter) = color centre_color; centre_color := (cola + colb + colc) / 3; LinearIntTriangle((pa + pb + pc) / 3, pa, pb, centre_color, cola, colb, n_iter); LinearIntTriangle((pa + pb + pc) / 3, pb, pc, centre_color, colb, colc, n_iter); LinearIntTriangle((pa + pb + pc) / 3, pc, pa, centre_color, colc, cola, n_iter); enddef; color cola, colb, colc; cola := (0,1,0); colb := (1,0,0); colc := (0,0,1); LinearIntTriangleB((0,0), (50,50*(3**0.5)), (100,0), cola, colb, colc, 10); \stopMPpage ____________________________________________________________ This approach gives ‘good enough’ results for large values of n_iter. However, the size of the generated pdf is somewhat larger than the pgfplots version: for instance, the first version above generates a 5KiB pdf versus 3.8KiB for the pgfplots version, while being somewhat less accurate. Increasing n_iter to 100 gives a result which is (to my not-very-good eyes) very close to the pgfplots version but the pdf size increases to about 20KiB, and takes significantly longer to render using MuPDF. I'd be grateful if someone could point me to a better way to generate such shadings in MetaFun / MetaPost. Cheers, Florent

TeXShop macro to open PDF in thumbnail view
by Bruce Horrocks 10 Jan '25

10 Jan '25

If you are using TeXShop on a Mac, you may have noticed that it has a "View pdf with Preview" macro in the Macros->AppleScript menu. As well as showing full pages, Preview also has the ability to view a PDF as a series of thumbnails which I find useful for seeing the impact of a change across the whole document. Modifying the existing macro to open in thumbnail view is simple if you want to do the same. <https://wiki.contextgarden.net/TeXShop#Viewing_the_PDF_in_Preview_using_thu…> Regards, — Bruce Horrocks Hampshire, UK

Touch my cow: Overlaying a picture with links to text
by Axel Kielhorn 09 Jan '25

Hello, I’m trying to make our documentation more interactive. So far I managed to turn the labels in the picture into links. The next step would be to mark certain areas in the picture. When the reader clicks on these areas, they will follow the link. This is where I am so far: % !TEX TS-program = ConTeXt (LMTX) \setupinteraction[state=start, color=middleblue] \placebookmarks[section] \setupexternalfigures[location=default] \starttext \startMPinclusions color mycolor; def gridscaled = pair ur; ur = urcorner currentpicture; width := xpart ur; height := ypart ur; xstep := ceiling(width / 10); ystep := ceiling(height / 10); enddef; % Bottom: The annotation is at the bottom of the start point def annotb (expr a, b, c, d) (text t) = label.bot ("\framed[background=color,backgroundcolor=transparentwhite,align=normal,corner=00,frame=no]{" & t &"}", (a * xstep, b * ystep)); drawarrow (a * xstep, b * ystep) -- ( c * xstep, d * ystep) withpen pencircle scaled .8mm withcolor white; drawarrow (a * xstep, b * ystep) -- ( c * xstep, d * ystep) withpen pencircle scaled .5mm withcolor mycolor; enddef ; % Top: The annotation is on top of the start point def annott (expr a, b, c, d) (text t) = label.top ("\framed[background=color,backgroundcolor=transparentwhite,align=normal,corner=00,frame=no]{" & t &"}", (a * xstep, b * ystep)); drawarrow (a * xstep, b * ystep) -- ( c * xstep, d * ystep) withpen pencircle scaled .8mm withcolor white; drawarrow (a * xstep, b * ystep) -- ( c * xstep, d * ystep) withpen pencircle scaled .5mm withcolor mycolor; enddef ; % Right: The annotation is on the right of the start point def annotr (expr a, b, c, d) (text t) = label.rt (t, (a * xstep, b * ystep)); drawarrow (a * xstep, b * ystep) -- ( c * xstep, d * ystep) withpen pencircle scaled .8mm withcolor white; drawarrow (a * xstep, b * ystep) -- ( c * xstep, d * ystep) withpen pencircle scaled .5mm withcolor mycolor; enddef ; % Left: The annotation is on the left of the start point def annotl (expr a, b, c, d) (text t) = label.lft (t, (a * xstep, b * ystep)); drawarrow (a * xstep, b * ystep) -- ( c * xstep, d * ystep) withpen pencircle scaled .8mm withcolor white; drawarrow (a * xstep, b * ystep) -- ( c * xstep, d * ystep) withpen pencircle scaled .5mm withcolor mycolor; enddef ; % touchtolink def touchtolink (expr a, b) (text t) = label ("\framed[background=color,backgroundcolor=transparentwhite,align=normal,corner=00,frame=no]{" & t &"}", (a * xstep, b * ystep)); enddef ; \stopMPinclusions \startMPpage % Picture draw externalfigure "cow.pdf" xsized 16cm; % Grid gridscaled; % Text annotb (1, 5, .8, 7.3, "\goto{Maul}[Maul]"); touchtolink (.8, 7.3, "\goto{\blackrule[height=2cm, width=4cm, color=transparentwhite]}[Maul]"); annotb (6, 2, 7, 3.2, "\goto{Euter}[Euter]"); annott (9.2, 9.5, 9.6, 3, "Schwanz"); annotb (3, -.5, 3.1, .9, "\goto{Huf}[Huf]"); annotb (3, -.5, 3.9, 1.1, ""); \stopMPpage \startsection[ title={Das Maul}, reference=Maul, bookmark={Maul}, ] Lorem ipsum dolor \stopsection \startsection[ title={Die Hufe}, reference=Huf, bookmark={Huf}, ] Lorem ipsum dolor \stopsection \startsection[ title={Das Euter}, reference=Euter, bookmark={Euter}, ] Lorem ipsum dolor \stopsection \stoptext %%%% I filled the area with a \blackrule, which is transparent and the link works.

Yet Another itemize question
by Jim 08 Jan '25

08 Jan '25

Hi everyone, I am using the following sort of structure: Latest news: \startitemize[distance=7.5em,leftmargindistance=2em,] \sym {Bob Loblaw} blah blah blah \sym {Sally Smithers} yada yada yada \stopitemize However, I wanted to achieve a "packed" list, so I tried Latest news: \startitemize[packed,distance=7.5em,leftmargindistance=2em,] \sym {Bob Loblaw} blah blah blah \sym {Sally Smithers} yada yada yada \stopitemize and, as you can see if you try it, the "packed" is completely ignored. I discovered that using either the distance= or the leftmargindistance= parameters "cancels" the "packed". I looked at the documentation I could (relatively easily) find, and I have not discovered either (1) why distance and leftmargindistance "cancel" packed, nor (2) how to uncancel this cancellation. I can work around this in a number of ways (including setting \setupitemize[1][width=<some suitable amount>] ) but I'd prefer to avoid kludgy work-arounds if at all possible. Can anyone tell me The Right Way to do this? Thanks. Jim

You’re invited to this year’s first regular online meet-up, this upcoming Wednesday, January 8th, 19:00 CET (UTC+1) at https://lecture.senfcall.de/hen-rbr-rku-oke (same, but shorter: https://u.mtxrun.eu/ctxmtg) ConTeXt users of all levels are welcome! Looking forward to seeing you, Hraban (I’m really looking forward to check out the new column features, but at the moment I’m in songbook mode – I’m helping my former scouts-like youth association to make a new songbook instead of still singing from the booklets I made ~30 years ago.) (Same blurb as always:) [Howto] * No special software installation required; most modern browsers should work (WebRTC required). * Open the URL above, 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. * Sometimes leaving and re-entering helps. * 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...

The newest ConTeXt but with Lua 5.4?
by LPr Pontex 07 Jan '25

07 Jan '25

Hello community, I'm looking for someone with the newest ConTeXt installed: - with ConTeXt which still uses Lua 5.4 - should not originate after 24.1.2024 - that's the time of the latest ConTeXt-with-Lua-5.4 was released, (newer, including the newest/beta ConTeXt versions use Lua 5.5 which is under developpement) - 32b platform, Windows. I need this due to some 3rd party library dependencies. I also downloaded the whole ConTeXt (and LuaMetaTeX and so) sources from the desired date but I'm not able to build them... You can write me to the (private) LPr.pontex(a)gmail.com to prevent polluting this mailing list. If I find someone, I'd like to get his ConTeXt installation tree via temporary cloud upload... Thank you! Best regards, Lukas

VIM typing vs. Context environments
by Ryszard Kubiak 07 Jan '25

07 Jan '25

Hi, I don't know whether the audience of this mailing list can help me with a problem concerning the VIM module or I should personally ask Aditya for help. The problem is that when I define an environment based on VIM's mechanisms and use this environment surrounded with ConTeXt's narrowing commands then these commands are ignored. You can see this effect in the PDF obtained by contexting the script given below. Best Regards Ryszard \setupbodyfont[12pt] \setuppagenumbering[state=stop] \parindent=0pt\parskip=2ex \usemodule[vim] \definevimtyping[PY][syntax=python, before={\bgroup\switchtobodyfont[9pt]}, after={\egroup}] \starttext Text before a narrowed block. \startnarrower[left] Text starting a narrowed block. \startPY #: The bonds file is absolutely vital for Fontplant to work. That's why we #: define a function to verify its existence on disk. \stopPY Text finishing a narrowed block. \stopnarrower Text after a narrowed block. \stoptext

Bug in recent math parsing (?)
by Jim 06 Jan '25

06 Jan '25

Hi, I was perusing an update to https://wiki.contextgarden.net/index.php?title=Framed&diff=next&oldid=35583 and noticed that the grey math was not properly aligned on the wiki page. But then I tried it on my system, and, worse yet, I found out that \setuppapersize[A5] \setupcolors[state=start] \def\graymath{\mframed[frame=off, background=color, backgroundcolor=gray, backgroundoffset=3pt]} \starttext \startformula {x^3\over3} - 2 \stopformula \stoptext creates a fraction that I would expect from {x^3\over3 - 2} Is this just my (newly updated) context, or has the year 2025 started off with a \over problem? Thanks. Jim

Hi, Some of you may have noticed that Garulfoo is very busy working on improving the ConTeXt wiki. One of the areas that could be improved: the bitmap images that are generated from <context> tags in the wiki pages. To optimize the effect of the improved image generation, I deleted all the old tex-generated images and cleared the page cache, but clearing the mediawiki page cache does behave a bit erratic at times. Sometimes pages will refuse to auto-regenerate without manual intervention and need a bit of help. If/when you run into a page with "broken image" links, see if ”edit & save” the page without making changes fixes it. Doing so should trigger the regeneration thanks to the code that executes during the “save” step. If the page is still broken after that, please send us a warning at wiki(a)contextgarden.net Best wishes, Taco

[ layout templates ]
by vm 06 Jan '25

06 Jan '25

I missed the first part of the presentation on the new features in lmtx that seem to provide support for layout templates. Is it possible to define page layouts containing shapes where text can flow into? And can you connect chains of shapes / templates? e.g. define a section to start with a particular template to be continued with a different template for following pages? Where can I find documentation? .Floris

Clip an image with a svg
by juh+ntg-context＠mailbox.org 03 Jan '25

03 Jan '25

Dear all, I found this example in the garden. \startMPclip{circleclip} clip currentpicture to fullcircle shifted (.5,.5) xscaled \width yscaled \height ; \stopMPclip \clip[nx=1,ny=1,mp=circleclip]{\externalfigure[hacker.png]} Aside from the fact that I failed to understand the shifted argument by playing around with values, I wonder if it is possible to use a SVG as clip for an image. The SVG is something like this: <?xml version="1.0" encoding="UTF-8"?>  <svg width="20.887mm" height="17.613mm" version="1.1" viewBox="0 0 20.887 17.613" xmlns="http://www.w3.org/2000/svg"> <g transform="translate(152.66 -101.94)"> <path d="m-150.94 114.93c-0.5424-1.3121-0.58209-2.9382 0.18256-5.2163 2.3566-7.0175 11.139-8.7098 15.878-3.0594 7.6978 8.7032-11.506 16.052-16.06 8.2756" fill="none" stroke="#dd4901" stroke-linecap="round" stroke-width="2"/> </g> </svg> I guess that there might be a way to translate this to Metafun or Metapost, if I can't use SVG directly. In my real life use case I want to have a bleeding image at the top or the bottom of the page which can be clipped by the form while size and position of the form relative to the image and relative to the page shall be set by parameters either in \clip or in the definition of the MPclip. TIA juh

How to control specific cells in setupTABLE?
by Joel 02 Jan '25

02 Jan '25

I used this code to create a "logic grid puzzle". See this picture (https://en.wikipedia.org/wiki/Logic_puzzle#/media/File:Logic_grid.png) for how it should appear. I'm having trouble getting the grid to show up right, I made a thicker grid (1pt) to the right of cols 1, 6, 11, and 16, but when rendering the other thinner rules, it creates strange problems, with some cell having thick rules on the bottom too. Additionally, I can't figure how to make the stair-step effect by turning off the borders of some cells. I can't find any instructions in the manual fro how to specify specific cells or a range of cells that won't be getting borders. Any suggestions how to make it look like the table in the picture? --Joel \starttext \startsetups[logicGrid] \setupTABLE[topframe=off, bottomframe=off, leftframe=off, rightframe=off] \setupTABLE[r][1][height=1in] \setupTABLE[c][1][leftframe=off,rightframe=off,width=1in,align={middle,right}] \setupTABLE[c][each][align={middle,center},height=0.25in,width=0.25in] \setupTABLE[c][2:16][align={middle,center}] \setupTABLE[r][each][align={middle,center}] \setupTABLE[c][1,6,11,16][rightframe=on, rulethickness=1pt] \setupTABLE[c][2,3,4,5,7,8,9,10,12,13,14,15][rightframe=on, rulethickness=.5pt] \setupTABLE[r][1,6,11,16][bottomframe=on, rulethickness=1pt] \setupTABLE[r][2,3,4,5,7,8,9,10,12,13,14,15][bottomframe=on, rulethickness=.5pt] \stopsetups \setvalue{topLabel1}{Red} \setvalue{topLabel2}{Yellow} \setvalue{topLabel3}{Green} \setvalue{topLabel4}{Blue} \setvalue{topLabel5}{12} \setvalue{topLabel6}{15} \setvalue{topLabel7}{18} \setvalue{topLabel8}{21} \setvalue{topLabel9}{Marmite} \setvalue{topLabel10}{Honey} \setvalue{topLabel11}{Jam} \setvalue{topLabel12}{Marmalade} \setvalue{topLabel13}{Extra1} \setvalue{topLabel14}{Extra2} \setvalue{topLabel15}{Extra3} \setvalue{sideLabel1}{Peter} \setvalue{sideLabel2}{Jane} \setvalue{sideLabel3}{Simon} \setvalue{sideLabel4}{Alice} \setvalue{sideLabel5}{Marmite} \setvalue{sideLabel6}{Honey} \setvalue{sideLabel7}{Marmalade} \setvalue{sideLabel8}{Jam} \setvalue{sideLabel9}{Label9} \setvalue{sideLabel10}{Label10} \setvalue{sideLabel11}{Label11} \setvalue{sideLabel12}{Label12} \setvalue{sideLabel13}{Label13} \setvalue{sideLabel14}{Label14} \setvalue{sideLabel15}{Label15} \bTABLE[setups=logicGrid] % Top labels \bTR \bTD \eTD \bTD \rotate[rotation=-90]{\getvalue{topLabel1}} \eTD \bTD \rotate[rotation=-90]{\getvalue{topLabel2}} \eTD \bTD \rotate[rotation=-90]{\getvalue{topLabel3}} \eTD \bTD \rotate[rotation=-90]{\getvalue{topLabel4}} \eTD \bTD \rotate[rotation=-90]{\getvalue{topLabel5}} \eTD \bTD \rotate[rotation=-90]{\getvalue{topLabel6}} \eTD \bTD \rotate[rotation=-90]{\getvalue{topLabel7}} \eTD \bTD \rotate[rotation=-90]{\getvalue{topLabel8}} \eTD \bTD \rotate[rotation=-90]{\getvalue{topLabel9}} \eTD \bTD \rotate[rotation=-90]{\getvalue{topLabel10}} \eTD \bTD \rotate[rotation=-90]{\getvalue{topLabel11}} \eTD \bTD \rotate[rotation=-90]{\getvalue{topLabel12}} \eTD \bTD \rotate[rotation=-90]{\getvalue{topLabel13}} \eTD \bTD \rotate[rotation=-90]{\getvalue{topLabel14}} \eTD \bTD \rotate[rotation=-90]{\getvalue{topLabel15}} \eTD \eTR % Side labels and grid rows \bTR \bTD[left] \getvalue{sideLabel1} \eTD \dorecurse{15}{\bTD \emptylines[1] \eTD} \eTR \bTR \bTD[left] \getvalue{sideLabel2} \eTD \dorecurse{15}{\bTD \emptylines[1] \eTD} \eTR \bTR \bTD[left] \getvalue{sideLabel3} \eTD \dorecurse{15}{\bTD \emptylines[1] \eTD} \eTR \bTR \bTD[left] \getvalue{sideLabel4} \eTD \dorecurse{15}{\bTD \emptylines[1] \eTD} \eTR \bTR \bTD[left] \getvalue{sideLabel5} \eTD \dorecurse{15}{\bTD \emptylines[1] \eTD} \eTR \bTR \bTD[left] \getvalue{sideLabel6} \eTD \dorecurse{15}{\bTD \emptylines[1] \eTD} \eTR \bTR \bTD[left] \getvalue{sideLabel7} \eTD \dorecurse{15}{\bTD \emptylines[1] \eTD} \eTR \bTR \bTD[left] \getvalue{sideLabel8} \eTD \dorecurse{15}{\bTD \emptylines[1] \eTD} \eTR \bTR \bTD[left] \getvalue{sideLabel9} \eTD \dorecurse{15}{\bTD \emptylines[1] \eTD} \eTR \bTR \bTD[left] \getvalue{sideLabel10} \eTD \dorecurse{15}{\bTD \emptylines[1] \eTD} \eTR \bTR \bTD[left] \getvalue{sideLabel11} \eTD \dorecurse{15}{\bTD \emptylines[1] \eTD} \eTR \bTR \bTD[left] \getvalue{sideLabel12} \eTD \dorecurse{15}{\bTD \emptylines[1] \eTD} \eTR \bTR \bTD[left] \getvalue{sideLabel13} \eTD \dorecurse{15}{\bTD \emptylines[1] \eTD} \eTR \bTR \bTD[left] \getvalue{sideLabel14} \eTD \dorecurse{15}{\bTD \emptylines[1] \eTD} \eTR \bTR \bTD[left] \getvalue{sideLabel15} \eTD \dorecurse{15}{\bTD \emptylines[1] \eTD} \eTR \eTABLE \stoptext

whitespace inside synonym
by damien＠thiriet.web4me.fr 02 Jan '25

02 Jan '25

Hello, I am using the synonym mechanizm to design a glossary for my pupils. I am stuck with this: how can I insert a whitespace inside a synonym definition? What I achieved yet is: \definesynonyms [vocabulaire] [vocabulaire] [\LaDef] \starttext \vocabulaire{Unionpersonnelle}{Deux États sont en union personnelle lorsqu’ils ont le même souverain} \Unionpersonnelle\ \placelistofvocabulaire \stoptext I would like to typeset Union personnelle, without inserting a UTF-8 non breakable space. I tried {{Union personnelle}}, but don't know how may I escape the space in the macro. The answer may lay in lowlevel-macro, but I couldn't find it. Happy new year everyone! Damien Thiriet
