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

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. 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, ...
