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
by Henning Hraban Ramm 13 Jan '25

13 Jan '25

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 ?
by Jim 13 Jan '25

13 Jan '25

Hi, In plain TeX, $$\smash{\sum_0^n}$$ is set in \displaystyle, just like $$\smash{\sum_0^n}$$ However, ConTeXt \starttext $$\smash{\sum^0_n}$$ \stoptext outputs the above in \textstyle, whereas \starttext $$\sum^0_n$$ \stoptext is in (of course(?)) \displaystyle. Is this difference intentional? Thanks. Jim
