does \setuplayout[grid=yes] require \startformula[split=line] ?
by garulfo＠azules.eu 29 Jan '25

29 Jan '25

Hi, sorry for the potentially puzzling title. I try to figure out why \setuplayout[grid=yes] seems to insert a line break in a short formula. Is there a way of ensuring regular vertical alignment of the formula number without ‘split=line’ ? Many thanks for your help. %%% START \setuppapersize[A6,landscape] \enabletrackers[math.showmargins.less] \startsetups[math:penalties:mathincontext] \shapingpenaltiesmode \zerocount \widowpenalties 3 5000 250 100 \clubpenalties 3 5000 250 100 \stopsetups \setupformula [split=mathincontext] \starttext Text \startplaceformula \startformula c^2 = a^2 + b^2 \stopformula \stopplaceformula \setuplayout[grid=yes] \page Text \startplaceformula \startformula c^2 = a^2 + b^2 \stopformula \stopplaceformula \page Text \startplaceformula \startformula[split=line,numberlocation=overlay] c^2 = a^2 + b^2 \stopformula \stopplaceformula \disabletrackers[math.showmargins.less] \stoptext %%% END

What would be the simple preferred way to define a document having not just odd and even pages but also alternating width is sets of two. e.g. two pages with width 118 mm followed by two pages of 178 mm followed by two pages with width 118 mm, ... all hints appreciated .Floris

How to load external lua library
by krulis.tomas＠seznam.cz 25 Jan '25

25 Jan '25

Dear ConTeXt mailing list, I've been struggling with loading the sqlite external lua library. I tried the following: 1. Instaling the system package and running ConTeXt with the `--permitloadlib` option (I am running Manjaro, an arch-linux derivative: https://archlinux.org/packages/core/x86_64/sqlite/) 2. Installing the luarocks package (https://luarocks.org/modules/dougcurrie/lsqlite3) for the 5.1, 5.3 and 5.4 lua versions. I also tried to symlink the files in $HOME/.luarocks/lib/lua/{version}/lsqlite3.so to the project directory 3. I tried also setting the relevant lua paths with `eval $(luarocks path)`. The compilation always fails with an error that context can't locate the sqlite3 library. How can I load data from sqlite database during context compilation? As an MWE, I am adding the example in the documentation for the interaction with sqlite from the context garden (https://www.pragma-ade.nl/general/manuals/sql-mkiv.pdf) ```tex \starttext \startluacode require("util-sql") utilities.sql.setmethod("sqlite") require("util-sql-loggers") local loggers = utilities.sql.loggers local presets = { -- method = "sqlite", database = "loggertest", datatable = "loggers", id = "loggers", } os.remove("loggertest.db") -- start fresh local db = loggers.createdb(presets) loggers.save(db, { -- variant 1: data subtable type = "error", action = "process", data = { filename = "test-1", message = "whatever a" } } ) loggers.save(db, { -- variant 2: flat table type = "warning", action = "process", filename = "test-2", message = "whatever b" } ) local result = loggers.collect(db, { start = { day = 1, month = 1, year = 2016, }, stop = { day = 31, month = 12, year = 2116, }, limit = 1000000, -- type = "error", action = "process" }) context.starttabulate { "||||||" } for i=1,#result do local r = result[i] context.NC() context(r.time) context.NC() context(r.type) context.NC() context(r.action) if r.data then context.NC() context(r.data.filename) context.NC() context(r.data.message) else context.NC() context.NC() end context.NC() context.NR() end context.stoptabulate() -- local result = loggers.cleanup(db, { -- before = { -- day = 1, -- month = 1, -- year = 2117, -- }, -- }) \stopluacode \stoptext ``` I am sorry for the poor quality of the example, but I don't know how to add an attachment to a message in a mailing list. I have found a few references on the web and on this mailing list (https://mailman.ntg.nl/archives/list/ntg-context@ntg.nl/message/IDZBJQIXG3J…) but I wasn't able to figure out what I could be doing wrong. I found a reference that the issue might be a version mismatch, so I tested multiple lua versions. My project is about using multiple data sources in multiple formats and creating reports from them. I know I will definitely need to load YAML as well (with the `lyaml` luarocks package I guess). There's always the alternative of trying to use other programs to get the data, but I was wondering if I could leverage ConTeXt to do that directly. Thank you for any guidance on this, and I hope this message is not too long ...

Decreasing size of the section number according to its level
by garulfo＠azules.eu 24 Jan '25

24 Jan '25

Hi, in setuphead, I try to get a decreasing size of the section number according to its level with \defineconversion and \definestructureconversionset. It works as expected for the first levels, but between 6th and 7th, the variation doesn't occur. Any clue about what is happening ? For the MVE, I've added a visual check in dark red to show the discrepancy. \setuppapersize[A5] \define[1]\NivA{\tfc #1} \defineconversion[NA][\NivA] \define[1]\NivB{\tfb #1} \defineconversion[NB][\NivB] \define[1]\NivC{\tfa #1} \defineconversion[NC][\NivC] \define[1]\NivD{\tf #1} \defineconversion[ND][\NivD] \define[1]\NivE{\tfx #1} \defineconversion[ND][\NivE] \definestructureconversionset [mysectionnumbers] [N,N,NA,NB,NC,ND,NE] [N] \definestructureconversionset [mysectionnumbersforlist] [N] [N] \setupheads [sectionconversionset=mysectionnumbers] \setuplist [section, subsection, subsubsection, subsubsubsection, subsubsubsubsection] [numberconversionset=mysectionnumbersforlist] \starttext \placecontent \startsection [title={Section}] \startsubsection [title={SubSection}] \startsubsubsection [title={SubSubSection}] \startsubsubsubsection [title={SubSubSubSection}] \startsubsubsubsubsection [title={SubSubSubSubSection}] \stopsubsubsubsubsection \stopsubsubsubsection \stopsubsubsection \stopsubsection \stopsection \color[darkred]{{\tfc 1.}{\tfb 1.}{\tfa 1.}{\tf 1.}{\tfx 1}} \stoptext

wiki update
by garulfo＠azules.eu 19 Jan '25

19 Jan '25

Hi all, for your information, many significant changes have been done on the wiki pages and their structure. Many pages are now nested by theme to make it easier for new ConTeXt users to navigate (by giving them a better overview of the material available on a given subject) and for wiki users to identify duplicates and old content. Of course, there are still “duplicates”, “aging content” and “unclear tutorials”, but the changes are significant and should be noted here. - Summary of changes - https://wiki.contextgarden.net/Talk:Main_Page#January_2025.2C_improving_wik… - Before / After illustrations - https://wiki.contextgarden.net/User:Garulfoo#January_2025_Wiki_before_.2F_a… Hoping that these improvements will compensate for the disruption to your habits and the inconveniences of recent weeks.

New module to typeset Pandoc JSON files (as XML) in ConTeXt
by mf 18 Jan '25

18 Jan '25

Hello, I just uploaded a module for ConTeXt to typeset Pandoc JSON files (as XML) with ConTeXt. You can find it here: https://github.com/massifrg/t-pandocxml I made a script to create a t-pandocxml-YYYY-MM-DD.zip file (see the devhelpers directory). But I don't know how to install it, starting from the zip file. This is what I did: - cd [context_installation_dir]/tex/texmf-context - unzip .../t-pandocxml-YYYY-MM-DD.zip - rm LICENSE README.md VERSION - mtxrun --generate It works, but I'm sure there's a better way to install it.

defining macros
by Henning Hraban Ramm 14 Jan '25

14 Jan '25

Hi, I just recognized that I’m not sure how to define a macro with optional and mandatory arguments the best way. E.g. (oldfashioned) \def\doMyMacro[#1]#2% {Do something ... \iffirstargument #1\fi #2} \def\MyMacro% {\dosingleargument\doMyMacro} Is this still the way to do it? Does it also work with \define? I have more questions like that: From Wolfgang’s presentation (article in progress…) I know all the cool stuff for modules (namespaces, setup helpers…), I also know the Lua way of interface.implement, but how to combine those? When should I use brackets or other characters in a definition, when not? Which docs should I read? Hraban

Weird date output
by autumnus 14 Jan '25

14 Jan '25

hi, When I try to output the Chinese date with the command below, I find that it doesn't process the month at all. No matter how I try any of the "month,month:cn-a,month:cn-c,month:cn-d" conversions Unless I pre-set the labeltext for the Chinese month. %%%% \definedfont[name:adobesongstdlight] \currentdate[year:cn-d,年,month:cn-a,day:cn,号] %output : 二〇二五年January 十一号 \setuplabeltext [en][january={一月},] \currentdate[year:cn-d,年,month:cn-a,day:cn,号] %output : 二〇二五年一月十一号 %%%% If so, then when should I use those conversion method ? (At present, the output of "month:cn-d" is only suitable for the year, not the month and day. Its naming is somewhat misleading) What's more, there seems to be a strange space here between the month and the day. It should output 二〇二五年一月十一号 instead 二〇二五年一月十一号 autumnus

OT: Tetris & Doom ported to PDF

Apparently, the PDF engines of Firefox and Chrome support enough JavaScript to play Doom (in 6 grayscales): https://github.com/ading2210/doompdf or (much easier) Tetris: https://github.com/ThomasRinsma/pdftris That might mean we could check support for presentations fetures (OCGs?) again. “C code can be compiled to run within a PDF using and old version of Emscripten that targets asm.js instead of WebAssembly.” Hraban

Spacing between Chapter title and first paragraph sometimes changes
by Keith McKay 13 Jan '25

13 Jan '25

H, I'm typesetting a memoir for a friend and I've come across a strange problem which I'm trying to solve. The memoir will be A5 format and has quite a few chapters which are less than a page long. I noticed that for some chapters the distance between the the chapter head and the first paragraph were not aligned in double page view. You can see this quite clearly in the attached screenshot. I was given a docx file consisting of 80 chapters and and appendices which I converted to individual xhtml files. The resulting xhtml files are very simple and the format is as follows: <?xml version="1.0" encoding="utf-8"?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <link rel="stylesheet" href="../styles/style001.css" type="text/css" /> <title></title> </head> <body> <h2 id="heading_id_no>Chapter Number</h2> <p>Some text</p> <p>Some text</p> <p>And so on...</p> </body> </html> In some of the xhtml files I have added <div>...</div> for layout purposes and also inserted images. I use xmlsetups to typeset the tags as follows: \startxmlsetups xml:html \xmlflush{#1} \stopxmlsetups \startxmlsetups xml:body \xmlflush{#1} \stopxmlsetups \startxmlsetups xml:h2 \page \chapter{\xmlflush{#1}} \stopxmlsetups \startxmlsetups xml:p \xmlflush{#1}\par \stopxmlsetups along with a few others for divs, images and some other tags. For the chapters setup I use: \setuphead[chapter][page=no, number=no, header=empty, align=middle, after={\blank[3cm]}] I would expect that using this \setuphead, there should be a gap of three cm between the head text and the first paragraph, however in a few chapters this does not happen and an extra blank line is either added or subtracted to the gap. I'm obviously missing something simple and struggling to find a solution to correct this problem so I would be grateful for any hints on how to go about it. Best Wishes Keith McKay

How hard should something get \smash-ed ?

Fwd: Call for Papers / BachoTeX 2025
by Henning Hraban Ramm 12 Jan '25

12 Jan '25

The 30th GUST TeX conference - call for papers ***TeX in education*** The jubilee, thirtieth BachoTeX conference is dedicated to using TeX in and for education. Though TeX is known and used in Poland at academia, especially in STEM, for more than thirty years it still is a niche tool at lower levels of education. The aim of this year’s conference is to look at how TeX may be used to support education processes in different contexts: pupils at various levels, teachers, authors of curricula, school management or persons less obvious in this context such as carers of special interest groups and others involved in school’s life. Those who contribute to education processes should be able to see the value of and potential offered by the TeX system – be it for preparing teaching materials or creating tools to support everyday school activities – TeX’s advantages over other software systems or packages should be obvious. Authors are invited to submit papers not only directly on the conference theme, we encourage you also to relate to the 30th BachoTeX jubilee. We look forward to receiving inspirations and hearing of your experiences as impulses for further research and developments. * Papers/presentations Of course we also look forward to the normal mix of TeX, Metafont / Metapost (please, do not forget the fonts!), ConTeXt, LaTeX, and friends related presentations. We also do upkeep the BachoTeX trend in which we try to bring together programmers and designers of typographic systems, typographers and other users of such systems. The normal channel of offering papers is the emailing of proposals to the Program Committee, but before rushing off to the mailer, please consult the info for authors at https://bachotex.gust.org.pl/2025/auth_en.html. * Workshops and tutorials We look forward to proposals for TeX-related tutorials or introductions. If you have suggestions for tutorials or workshops by others than yourself or about specific topics, please let us know. * Poster sessions As always at BachoTeX participants will be given the opportunity to present their TeX and typographic results in the form of posters for which we provide exhibition space. * Deadlines and addresses The deadline for “regular” abstracts and other proposals is March 31th 2025. The deadline for final versions to appear in the conference materials is April 14th. Contributions should be sent by email using the address prog-2025(a)gust.org.pl.

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.

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

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.

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

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.

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

Wiki update
by Taco Hoekwater 06 Jan '25

06 Jan '25

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.

[ 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.

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

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

Hi, It's about end of the year, so I updated lmtx. The most significant "change" is that columnsets are in the processed of being replaced which involves a "change in approach". As a consequence, when you use that mechanism - we're not sure how many actually do - and want the old code to kick in you need to load the "oldcolumnsets" module. Mikael S and I have been working on the new implementation but are not finished. We plan to have a reasonable stable version around may 2025 and a release at the ctx 2025 meeting when we also hope to have a new (additional) manual ready. We also test on real (complex) documents which triggers new challenges and solutions. The current code works ok but can best not be used for production (and some new features are undocumented anyway). Teaser: deep down the approach is quite different from the previous one but more reliable and it produced better quality output. Columnsets are also the mechanism that parallel document(stream)s will use. Like upgraded math and (multipass) paragraph optimization the mechanisms used are also a quite fundamental extensions that will be documented independently and likely used elsewhere.

Issues with included images on some epub readers
by Florent Michel 28 Dec '24

28 Dec '24

Hi, I'm not sure whether the following is an issue with ConTeXt or with the epub readers I'm using; my apologies for the noise if it's not relevant to this list! I was experimenting creating ebooks with ConTeXt, and found it works very well on most epub readers (except with Calibre, as was previously reported on this list) as far as text is concerned, although I am having issues displaying images. Images appear correctly in the exported html file when opened with Firefox or Chromium, so I suspect the issue may either come from difference in specs for the epub and html formats or from bugs in the epub readers I have tried (Mupdf, Koodo, and Foliate). Example showing the issue: _____________________________________ % test.tex \setupbackend [export=yes] \setupinteraction [title={\documentvariable{title}}] \startdocument[title=Test EPUB] % Some text \samplefile{tufte} % Include a simple MetaPost image \starttextdisplay \startimage \startMPcode fill fullcircle scaled 3cm withcolor darkred ; \stopMPcode \stopimage \stoptextdisplay % Some text again \samplefile{tufte} % Include an equation as SVG image \starttextdisplay \startimage \startformula e = \frac{m c^2}{\sqrt{1 - v^2 / c^2}} \stopformula \stopimage \stoptextdisplay \stopdocument _____________________________________ I compile it using _____________________________________ mtxrun --script epub --images test.tex context test.tex mtxrun --script epub --make test.tex _____________________________________ Render from Koodo 1.5.1 (correct): https://pasteboard.co/4bUcUdaJim9m.png Render from Koodo's latest version (1.7.2): https://pasteboard.co/xRfDCYx9zki4.png All recent epub readers I have tried (Mupdf, Foliate, Okular) produce a similar incorrect rendering. I am not very familiar with the epub format specs so I don't have a good feel for where the issue may come from. It seems that manually adding <img alt="image-1" src="../images/test-exported-1.svg"> in the .html file makes it appear with recent epub readers, though. Is it possible to have the html output generated by ConTeXt include images in this way (or tune the way images are included in another way which may work better with recent epub readers)? Cheers, Florent

playing with dates
by Pablo Rodriguez 23 Dec '24

23 Dec '24

Dear list, I would like to be able to design some calendars. Is there any way to have a command (Lua or ConTeXt) that can increase or decrease a given date by days (something like \nextday or \previousday). I have tried \date and \increment or \decrement, as shown in the wiki: \starttext Today is \currentdate. \dorecurse{25} {\increment\normalday} Tomorrow will be \currentdate. \decrement\normalday %\increment\normalmonth% -- gives an error \increment\normalyear And today in a year will be \currentdate. \stoptext But the main problem is that I end up having the improbable day of December 41st, 2024 (with \decrement\normalday, it would read -9th). Besides, \normalmonth cannot be incremented or decremented (although this would be useless for me). Is there any way to get a command that can increment or decrement by days a given date? Many thanks for your help, Pablo

Hi, I use the following code to make a class material. When I use \startcolumns … \stopcolumns, the vertical space between section title and subsection title so big. 1. Is there a way to reduce the vertical space between them? 2. Is there a way to make section command simpler? Thank you for reading.

[ pdf images upside down in firefox ]
by vm 19 Dec '24

19 Dec '24

This is most likely an issue with firefox, but i noticed that when i create a file with z serie of images, the pdf shows correct in my local gnome document viewer (42.3) but when I vew the same file in firefox, for some unknow reasom the images are upside down. When I download the pdf, then view it with the local document viewer, the images are correct. When I drag the pdf into firefox, the turn upside down again. Is it related to the orientation option in the \externalfigure command that is not recognized by firefox? this is the code I use to place the images on the page: 8<--- \def\zzz#1{ \startTEXpage \externalfigure[2024/12/small/#1.JPG][width=\textwidth,orientation=180] \blank[10mm] \startcombination[3*1] {\externalfigure[2024/12/thumbs/#1a.JPG][width=0.316\textwidth,orientation=90]}{} {\externalfigure[2024/12/thumbs/#1b.JPG][width=0.316\textwidth,orientation=90]}{} {\externalfigure[2024/12/thumbs/#1c.JPG][width=0.316\textwidth,orientation=90]}{} \stopcombination \setcounter[userpage][\pagenumber+1] \stopTEXpage } \starttext \zzz{IMG_8616} \zzz{IMG_8617} ... \stoptext --->8

On the use of btx datasets to manage images and plots
by marco.riggirello.98＠gmail.com 19 Dec '24

19 Dec '24

Dear all, since this is my first post on the mailing lists, let me make a small preamble: after years of LaTeX experience I decided in May to give ConTeXt a try. The journey has been extremely pleasant up to now, so I want to thank all the contributors to this project for making such a great piece of software. Now, let's dig into the topic: I'm a PhD student in High Energy Physics (HEP) and my typical work include producing lot of plots and then presenting them in various meetings, comparing my results with existing ones present in the literature. Tipically, many plots and figures are re-used in different meetings and they might end up in the final thesis. My current workflow is just copying in different directories these (mostly vector) images and copying the caption between different tex sources. This workflow clearly scales very bad, and I would like to exploit all the goodies of the ConTeXt dataset machinery. In the Bibliografies manual it is mentioned that one can use datasets to manage images as well [1]. My case however is (slightly) more complicated than the one showed in the manual. What I would like to have is four databases: - a bibliography dataset; - an "others' figure" dataset, with all the images I took from the references. This means that in some way in the caption I would like to cite the references included in the bibliography dataset; - a "own figures" dataset, with the plots I produced with external programs; - a "metafun figures" dataset, pointing at the metafun code corresponding to some diagram. In my idea, for each figure dataset the \placebtxrendering should plot the figure with the right label to refer to in the main text and the right caption. (Clearly for the metafun dataset it should not include the pdf of the diagrams but instead compile the metafun code). In this way, I could create a single ConTeXt project with different products for different presentations, posters and other documents. Do you think this workflow can be implemented in ConTeXt? If so, how? Is btx the right tool for the job? I hope I was clear, and sorry if I was not. Thanks in advance for the help. Cheers MR [1] https://www.pragma-ade.nl/general/manuals/mkiv-publications.pdf#%5B%7B%22nu…

Strange character output when mixing different fonts
by autumnus 18 Dec '24

18 Dec '24

hi, When I mix the four fonts below, only the serif (mincho) outputs my characters correctly. However, if I only use any of these fonts for output, I will get normal characters. It's not clear to me if this is a bug with the font itself or what. If it's an issue with the fonts themselves, I'll report the bug to the designers of those fonts. But I'm not a programmer, so I'll only ask questions here. font: https://drive.google.com/drive/folders/1uk6fLzn8ZD0MeHSv78cFbQo4cclkOuly?us… 汇文明朝 -- huiwenmincho 汇文港黑 -- huiwenhkheiregular 汇文仿宋 -- huiwenfangsongregular 汇文正楷 -- huiwenzhengkairegular %%%%% \starttext { {\definedfont[name:huiwenmincho] Lorem Ipsum , 也称乱数假文}\par% normal {\definedfont[name:huiwenhkheiregular] Lorem Ipsum , 也称乱数假文}\par% normal {\definedfont[name:huiwenfangsongregular]Lorem Ipsum , 也称乱数假文}\par% abnormal {\definedfont[name:huiwenzhengkairegular]Lorem Ipsum , 也称乱数假文}% abnormal } \stoptext autumnus

Issue loading an otf variable font

understanding \writetolist and \writebetweenlist
by Henning Hraban Ramm 17 Dec '24

17 Dec '24

Hi, I’m trying to understand the ordering of list entries and find it really hard. Below is the content of "inbetween-01.tex" from the test suite, more or less the same was in https://wiki.contextgarden.ne/Command/writebetweenlist; I tried to enhance it but probably messed it up. Looking at the examples, I only partly understand what’s going on. * What’s the difference of \writetolist and \writebetweenlist WRT their connection to the place where they occur? This seems to be important. (\writetolist has a section number, \writebetweenlist hasn’t …) * What’s the difference between location="here", "none" or nothing with \writetolist? * In my notes, I found the remark that "between" items should be anchored to a paragraph (not being their own par) to avoid inserting whitespace. * The order of \placelist can be normal, command, all or title. The latter isn’t mentioned in the file below, but in the interface. I don’t understand the effect for "normal" or "all" in the example. - normal: there’s some reordering. - command: "only the commands": does this mean, sort the "between" entries by macro name or how? - all: everything in the order of occurrence (that’s clear) - title: sorted by title; how does this affect "between" entries? Hraban """ % inbetween-01.tex \definelist[testlist][criterium=all] \starttext Regular list entries are bound to a specific location in order to get the right pagenumber etc.\ associated. When pushing something inbetween (in mkiv) it ends up directly in the list. This is the default because otherwise users will wonder why spacing might get messed up (due to an unseen but present node). It is possible to force a location by explicitly setting \type {location} to \type {here}. Another way to force a certain order is to set the \type {order} variable when placing a list. The \type {command} option only pushes commands into the right order, and \type {all} orders all entries (which might be too much). In this case no specific location is needed with the inbetween method. Maybe additional mechanisms show up some day. \subject{normal} \placelist[testlist] \subject{command} \placelist[testlist][order=command] \subject{all} \placelist[testlist][order=all] \page \input tufte \writetolist [testlist] {1} {One} \writebetweenlist[testlist] {\blackrule[color=red,width=\hsize]} \writebetweenlist[testlist][location=here]{\blackrule[color=blue,width=\hsize]} \writetolist [testlist] {2} {Second} \writetolist [testlist][location=none]{W} {Whatever} \writebetweenlist[testlist] {\blackrule[color=green,width=\hsize]} \stoptext """

Would it possible to freeze the formula number? Thanks, Aditya

Including SVG manipulating color or rewrite in MP
by juh+ntg-context＠mailbox.org 14 Dec '24

14 Dec '24

Dear all, I have near to zero knowledge about MPgraphics, so I always use SVG files from various sources. I do something like this: \defineoverlay[pic][\externalfigure[form.svg][width=14em]] \defineframed [textcircledA] [ frame=off, strut=yes, rulethickness=0.0pt, background=pic, location=top,] \textcircledA{\externalfigure[icon.svg][width=280px]} The form.svg appears as background of icon.svg. Now I want to change the stroke color in the svg. It is very simple: <?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="#99bcdb" stroke-linecap="round" stroke-width="2"/> </g> </svg> I can simply open it in inkscape set the color an save it under a meaningful filename, but I would like to set the color in the context file. I tried to define the overlay pic with \includesvgbuffer but I can't get it to work. \startbuffer[svg] <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="MyColor" stroke-linecap="round" stroke-width="2"/> </g> </svg> \stopbuffer \defineoverlay[pic][\includesvgbuffer[svg][offset=1bp]] Nothing happens, no form appears in the overlay. I saw an example with \startstopuseMPgraphic in the Wiki. \startuseMPgraphic{MPtextcircle} path p; p := fullcircle xscaled OverlayWidth yscaled OverlayWidth; setbounds currentpicture to p ; % p:= p shifted (0,StrutDepth/2.7); draw p withpen pencircle scaled 25pt withcolor OverlayLineColor; \stopuseMPgraphic \defineoverlay[OLtextcircle][\useMPgraphic{MPtextcircle}] This works for me. Is it possible to use a svgbuffer in a overlay definition? Or do I have to convert the SVG code to MP? Is there a converter? TIA juh

How to make this Metapost diagram adjust to the width of text?
by Joel 09 Dec '24

09 Dec '24

I am using this to create a simple branched diagram, with one item, branches into two, and each of those two further branch into two. I'm running into two problems: (1) The lines cut right through the word "apple" and "banana", I need to place a node at the right of apple and banana that connects to sub-branches. In other words, I'd rather it have a broken line, ending at left of apple and then continuing at right of apple. (2) If you put longer text in the top category, it adjusts. And if you put longer text in the lowest branches, it adjusts, but I can't find a way to get the branches to adjust length to accommodate longer text in the middle, where apple and banana are. I tried using different code to find textwidth, but it isn't working: numeric text_width; text_width = width(textext("#2")); How can I make the diagram adjust if the words in the middle branches are longer? --Joel \starttext % Define the macro outside the Metapost code block \def\macroXa#1#2#3#4#5#6#7 { \startMPcode u := 1.5cm; % Reduced unit size for compact spacing % Main node positions z0 = (0, 0); % Fruit position z1 = (1u, 0); % Horizontal segment from Fruit z2 = (1u, 0.6u); % Apple position z3 = (1u, -0.6u); % Banana position z4 = (3u, 0.9u); % Fuji branch z5 = (3u, 0.3u); % Gala branch z6 = (3u, -0.3u);% Cavendish branch z7 = (3u, -0.9u);% Plantain branch z8 = (4u, 0.9u); % Fuji z9 = (4u, 0.3u); % Gala z10 = (4u, -0.3u); % Cavendish z11 = (4u, -0.9u); % Plantain % Main paths draw z0 -- z1; % Horizontal from Fruit draw z1 -- z2; % Line to Apple (90-degree angle) draw z1 -- z3; % Line to Banana (90-degree angle) % Apple sub-branches draw z2 -- (3u, 0.6u) -- z4; % Right angle to Fuji draw z2 -- (3u, 0.6u) -- z5; % Right angle to Gala % Banana sub-branches draw z3 -- (3u, -0.6u) -- z6; % Right angle to Cavendish draw z3 -- (3u, -0.6u) -- z7; % Right angle to Plantain % Final horizontal branches draw z4 -- z8; % Fuji draw z5 -- z9; % Gala draw z6 -- z10; % Cavendish draw z7 -- z11; % Plantain % Add labels using macro arguments label.lft(btex #1 etex, z0); % Fruit label.rt(btex #2 etex, z2); % Apple label.rt(btex #3 etex, z3); % Banana label.rt(btex #4 etex, z8); % Fuji label.rt(btex #5 etex, z9); % Gala label.rt(btex #6 etex, z10); % Cavendish label.rt(btex #7 etex, z11); % Plantain \stopMPcode } % Call the macro with labels \macroXa{Fruit}{Apple}{Banana}{Fuji}{Gala}{Cavendish}{Plantain} \macroXa{This text is longer}{Apple}{Banana}{Fuji}{Gala}{Cavendish}{Plantain} \macroXa{This text is longer}{Apple}{it needs to accomodate longer text here}{Fuji}{Gala}{Cavendish}{Plantain} \stoptext

Roman numerals typography
by damien＠thiriet.web4me.fr 07 Dec '24

07 Dec '24

Hello, In French typography, roman numerals are usually typeset being connected with a top bar and a lower bar, at least when it comes to century numbers (should be also small caps, something I discovered today). Since I am not sure my vocabulary suits to this reality, you can see a sample looking at photos displayed in this online article https://fr.cultura10.com/r%C3%A8gles-d%27%C3%A9criture-des-nombres-romains/ I have been simulating this with kerning for several years, but I recently switched from Latin Modern Sans to Luciole (both 24pt) for my presentations and I have to redesign this issue. So it is a good opportunity to find some a better alternative than stuff like \def\III{{\rm I\kern -1.3pt I\kern -1.3pt I}}, working at the font level or with a ConTeXt built-in macro. Several questions: 1) Is this already implemented in ConTeXt (I don't have time to reinvent the wheel once more)? The sample I looked at in the \Romannumeral wiki page doesn't implement this, but they may be alternative I am not aware of. 2) If it isn't, I think the best way would be to add a font extension, using hits given by Hans in the 11th meeting proceedings. However, what would be the best idea: playing with kerning, or with ligatures? Thanks for your advices, Damien Thiriet

Transition from ConTeXt mark II to mark IV
by Michal Kvasnička 06 Dec '24

06 Dec '24

Hallo. I need some help. I have all my teaching materials (slides, worksheets, and everything, including many MetaPost figures) in ConTeXt mark II. After the transition to Ubuntu 24.10, I found that the texexec is not a part of the ConTeXt distribution anymore. I tried to compile my stuff with context instead and failed. This is probably because the macros in my old modules (created by myself many years ago) are not compatible with mark IV. Hence my question: Is there any document on the transition from mark II to mark IV? Many thanks for your kind help. Best wishes, Michal

Dear all, I’d like to hide a part of a path. I can do that after changing it into an image, but it is not clearly erased. Is there a way to do that not changing it into an image? Thank you for reading. Best regards, Dalyoung \startMPcode path p,q; picture pic; numeric u; u:= 1cm; p := origin--(2u,0)--(3u,u)--(3u,0)--(4u,0); q := (3u,u)--(3u,0); pic := image(draw p; draw q withcolor white;); draw pic; \stopMPcode

Metapost lines with fancy line endings and connections
by Wolfgang Schuster 01 Dec '24

01 Dec '24

Hi, I have a bunch of similar graphics on a 7x7 where some lines have exceptions for the endings and connections. - When a line ends in one of the four corners the line end has an angle of 45 degrees. - When a line takes a turn the outer corner results also in a 45 degree angle. - Single points always use straight endings. - Lines which end outside of a corner end with a straight line. While I can get the desired result which a filled path I'm looking for a solution where I have to set fewer control points. The example below shows the simpler draw alternative where I need only a start and end point versus the outline alternative where I need at least twice as many points to get the desired output. \starttext \startuseMPgraphic{draw} draw hlingrid(0, 7, 1, 7, 7) withpen pencircle scaled 1/20 shifted (0.5,0.5) withcolor "darkgray" ; draw vlingrid(0, 7, 1, 7, 7) withpen pencircle scaled 1/20 shifted (0.5,0.5) withcolor "darkgray" ; pickup pensquare scaled 1; drawoptions(withcolor "red"); draw (1,7) -- (7,7) ; draw (1,1) -- (3,1) -- (3,5) ; draw (7,3) -- (5,3) -- (5,5) -- (7,5) ; draw (7,1) ; \stopuseMPgraphic \startuseMPgraphic{fill} draw hlingrid(0, 7, 1, 7, 7) withpen pencircle scaled 1/20 withcolor "darkgray" ; draw vlingrid(0, 7, 1, 7, 7) withpen pencircle scaled 1/20 withcolor "darkgray" ; drawoptions(withcolor "green"); fill (0,6) -- (7,6) -- (6,7) -- (1,7) -- cycle ; fill (1,0) -- (2,0) -- (3,1) -- (3,5) -- (2,5) -- (2,1) -- (0,1) -- cycle ; fill (7,2) -- (5,2) -- (4,3) -- (4,4) -- (5,5) -- (7,5) -- (7,4) -- (5,4) -- (5,3) -- (7,3) -- cycle ; fill (6,0) -- (7,0) -- (7,1) -- (6,1) -- cycle ; \stopuseMPgraphic \startcombination[2*1] {\scale[s=10]{\useMPgraphic{draw}}}{draw option} {\scale[s=10]{\useMPgraphic{fill}}}{fill option} \stopcombination \startoverlay {\scale[s=10]{\useMPgraphic{draw}}} {\scale[s=10]{\useMPgraphic{fill}}} \stopoverlay \stoptext Wolfgang

Line break after a Metapost picture at start of paragraph
by Florent Michel 29 Nov '24

29 Nov '24

Hi, I have just encountered a (to me) slightly surprising behaviour in ConTeXt LMTX 2024.10.31: there seems to be an automatic line break after a Metapost picture if it is at the start of a paragraph. Here is a simple example showing this behaviour: ------------------------------------------------------------------ \starttext % Two different lines \startMPcode fill fullcircle scaled 10pt; \stopMPcode text % Single line text \startMPcode fill fullcircle scaled 10pt; \stopMPcode \stoptext ------------------------------------------------------------------ I'm not sure whether this is a bug or intended behaviour, though - maybe this is the expected output for users more familiar with TeX and/or ConTeXt than I am. I would have two question, though: 1) Is there a canonical way to get the second behaviour (multiple Metapost pictures and text on the same line) if the first Metapost picture starts the paragraph? One workaround seems to be to add \noindent (plus \hskip if I do want indentation) before the first Metapost picture, but maybe there is a better way. 2) If this is intended behaviour, is there already a description of it in the Wiki or would it make sense for me to add it? Cheers, Florent

Why are my images floating away even though I used "here" and "force" settings?
by Joel 28 Nov '24

28 Nov '24

I have a textbook that includes images--and I don't care that they are placed wherever. But for the workbook, its confusing for the readers if the images float to another location. If the items don't appear in this order, it really gets confusing, as basically there is an activity that says "color the map" and students can't find the map--even if its just a page later. TitleInstructionsImageRequirements In other words, I can't have it float somewhere else, though if a page break is needed before it or after it, then that is okay, if that is what is needed to get it to appear. I thought "here" and "force" were supposed to be the commands to achieve this, but its still resulting in the image appearing after requirements or sometimes, after the next activity, which is too confusing to readers. \placefigure[here, force]{Map of New Mexico}{\externalfigure[map1a][width=.8\textwidth]} What more is needed to make it appear exactly as the next item after instructions, and before requirements, without floating away, even if that means a lot of empty space is going to be added to the page? --Joel

Why is framed text crashing into and overlapping other text?
by Joel 28 Nov '24

28 Nov '24

I have a simple enumeration structure like this: 1. word a. _________ b. _________ c. _________ The students will write three properties of each word. The problem I had is it was putting some items on a next page, which confused students. For instance, maybe it shows 1. word(pagebreak) a. _________ b. _________ c. _________ This confused students where to write their answers. (see Attempt 1 code below). So I used a frame to keep the itemized text together. (see Attempt 2 code below). Though in my minimum working example below, it works just fine, somehow in my document it creates weird problems putting frames around the items. Sometimes it puts item 10 on top of 9, so its like the text is written on top of the other text. Sometimes the frames make the text crash over the items after it. Is frame the write tool to use to keep the itemized items together as a group without allowing column and page breaks to separate them? How do I stop the strange behavior of the frames seemingly floating to weird locations and appearing over other text? I'm afraid I couldn't find any way to recreate this affect in my minimum working example. --Joel \starttext \subject{Attempt 1} \startcolumns[n=2] \startitemize[n] \dorecurse{30}{ \item word \startitemize[a] \item \thinrule \item \thinrule \item \thinrule \stopitemize } \stopitemize \stopcolumns \input knuth \subject{Attempt 2} \startcolumns[n=2] \startitemize[n] \dorecurse{30}{ \startframedtext[frame=off] \item word \startitemize[a] \item \thinrule \item \thinrule \item \thinrule \stopitemize \stopframedtext } \stopitemize \stopcolumns \input knuth \stoptext

I have found some situations in which I have content that interferes with footnotes. Can I tell ConText to delay showing the footnote for a page or two? And then when its safe again, all the footnotes that weren't displayed would be displayed on a later page? --Joel

Tikz CD
by Aditya Mahajan 26 Nov '24

26 Nov '24

Hi, There was a recent question about what appeared to be commutative diagrams, and I wanted to reply saying that one option is to use tikzcd module. However, testing showed that it fails. This is what tikzlibrarycd.code.tex does: % ConTeXt-specific stuff \pgfutil@IfUndefined{starttikzpicture}{}{% \def\starttikzcd{\tikzcd} \def\stoptikzcd{\endtikzcd} \tikzcdset{ every matrix/.append code={% \def\NC{\pgfmatrixnextcell}% \def\NR{\pgfmatrixendrow}}} } where \def\tikzcd@[#1]{% \tikzpicture[/tikz/commutative diagrams/.cd,every diagram,#1]% ...} So, it fails because \tikzpicture is being called with wrong catcodes. It can be fixed in the same manner as we patched tikzpicture as shown by the following MWE: \usemodule[tikz] \usetikzlibrary[cd] \permanent\protected\def\starttikzcd% {\starttikzinput \hcontainer\bgroup \tikzcd} \permanent\protected\def\stoptikzcd {\endtikzcd \egroup \stoptikzinput} \starttext \startformula \starttikzcd x \arrow[d] \NC A \arrow[d] \NC D \NR y \NC B \NC D \NR \stoptikzcd \stopformula \stoptext What is the best way to go about this? I can try to ask the Should we include a wrapper for tikzcd (as we do for circuitikz) or should I try to push a patch upstream. BTW, why do we need a \hcontainer in the above code? Aditya

How to put a ___ before enumerations in ConTeXt?

The problem I find it is looks really messy putting the ___ between the numbering and text, such when you get to numbers that are wider, like 10., the ___ doesn't line up right. I also think its too confusing this way for students to know what to write. Is there a way to move the ___ bit out front of the number? It would look like this: ____ 1. this is some text ____ 2. this is some text --Joel

Zigzag left margin with italics
by Rik Kabel 25 Nov '24

25 Nov '24

In a paper I recently wrote I noticed some ugly zigzag alignment on the left margin of one paragraph (set with Libertinus) where a couple of book titles appeared at the start of the second and fourth lines. The following example demonstrates the issue. \definefontfeature [default] [default] [protrusion=quality,expansion=quality] \setupalign [hz,hanging] \startbuffer Here is a line of text, the first sentence in the demonstration.\\ {\em Then} the next sentence in the paragraph follows.\\ You can see that the italic {\em T} appears to be a bit indented.\\ {\em There } might be a way to shift it to the left that little bit.\\ Perhaps a protrusion setting.\\ {\em This} does appear to depend to on the font used. With Modern and\\ Libertinus it is worse, with Times a bit better. \blank \stopbuffer \starttext Modern\\ \getbuffer Times\\ \setupbodyfont[times] \getbuffer Libertinus\\ \setupbodyfont[libertinus] \getbuffer \stoptext How can one set a small left-margin protrusion for the italic T and possibly other characters? I know it is a small issue, but once seen it is hard to un-see. -- Rik

A few question about defining symbols and creating downarrow to illustrate function rules

Hello, I have a few questions. 1. What is the best way to get a symbol from a font you are not using as your main? %% start MWE \starttext \definesymbol[cedis][\utfchar{“20B5}] \def\cedis{ \switchtobodyfont[dejavu]\tf\symbol[cedis] } I have GH\cedis 10.00 in my pocket \stoptext %% end MWE I tried to use \getglyph because I saw it being used in a similar way (but not with unicode characters) like this: \definesymbol[cedis][\getglyph{dejavu}{\utfchar{"20B5}}] It didn't work. 2. I would like a more robust method to create a diagram (ie., a series of input and outputs where you are then required to tell the rule of the mapping). The inputs will be up with the outputs below and a downward pointing arrow between them. %% start MWE \starttext \define[2]\xdownarrow{ \startframed[frame=off,offset=0pt,width=0.8cm] \startMPcode numeric u, w; u := .3cm; w := 2pt; pair pointX, pointY; path pointXY; pointX := origin; pointY := pointX shifted (0,-3u); draw pointX -- pointY withpen pencircle scaled .6w; drawarrow pointX -- pointY withpen pencircle scaled .6w; labeloffset := u; label.top (textext("\dm{#1}"), pointX); label.bot (textext("\dm{ #2 }"), pointY); \stopMPcode \stopframed } \startitemize[n] \item Find the rule of the mapping: \startplacefigure[location=none] \startframed[frame=off,offset=0pt,] \xdownarrow{x}{y} \hspace[big] \xdownarrow{1}{3} \hspace[big] \xdownarrow{2}{1} \hspace[big] \xdownarrow{3}{-1} \hspace[big] \xdownarrow{4}{-3} \hspace[big] \xdownarrow{5}{-5} \stopframed \stopplacefigure \startitemize[a] \item \im{y = 2x + 2} \item \im{y = -2x + 2} \item \im{y = 4x} \item \im{y = -2x + 5} \stopitemize \stopitemize %% stop MWR How can I achieve this more elegantly with better spacing and the arrow pointing to the number instead (-) for negative numbers?
