How to set section title based on section content?

How to set section title based on section content? I have a document that has some structures like this: \starttext \startsection[title={Animals}] \event{\input knuth } \stopsection \startsection[title={Books}] \event{\input knuth } \stopsection \stoptext The event macro runs a bunch of conditionals, deciding which content to place inside the section. It places any one of neary 200 possible different types of content there. Sadly when I wrote the code, I thought generic titles would be okay. Now I realize I need to be more specific, giving titles that match the content inside. I could move the section titles inside the \event macro, but it means rewriting ~200 other macros. In other words, how do I define a section title by defining it somewhere in the content of the \event macro? \starttext \startsection[\whatistitle] %<-- would display "Neon Tetras" \event{\thetitleis{Neon Tetras}\input knuth } \stopsection \startsection[\whatistitle] %<-- would display "Detective Stories" \event{\thetitleis{Detective Stories}\input knuth } \stopsection \stoptext

additional font faces

Hi, if I need an additional pair of upright and italic font faces, e.g. a Medium or Light version, would it make sense to define them like this: % adapted from font-pre.mkxl \definefontalternative[md] \definefontalternative[mi] \definefontalternative[ms] \definealternativestyle [medium] [\md] [] \definealternativestyle [mediumitalic,italicmedium] [\mi] [] \definealternativestyle [mediumslanted,slantedmedium][\ms] [] \definealternativestyle [sansmedium] [\ss\md] [] \definealternativestyle [serifmedium] [\rm\md] [] \definealternativestyle [monomedium] [\tt\md] [] %\definealternativestyle [mediumface] [\mediumface] [] \unexpanded\def\normalmd{\let\fontalternative\md\font_helpers_synchronize_font} \unexpanded\def\normalmi{\let\fontalternative\mi\font_helpers_synchronize_font} \unexpanded\def\normalms{\let\fontalternative\ms\font_helpers_synchronize_font} \let\md\normalmd \let\mi\normalmi \let\ms\normalms \definehighlight[medium ] [command=no,style=medium] \definehighlight[mediumitalic ] [command=no,style=mediumitalic] \definehighlight[mediumslanted] [command=no,style=mediumslanted] Is that necessary?

Log entries about confusing level change
by Rik Kabel 08 Mar '24

08 Mar '24

Hello all, The following example produces two log entries that seem a bit odd. The log entries are: backend > bookmarks > confusing level change at level 3 around '1 body1' backend > bookmarks > confusing level change at level 3 around 'back1' and they refer to the first chapter of the bodymatter and the first chapter of the backmatter, respectively. The example: \setupinteraction [state=start] \placebookmarks [chapter] \starttext \startfrontmatter \startchapter [title=front1] \samplefile {knuth-gpt} \stopchapter \stopfrontmatter \startbodymatter \startchapter [title=body1] \samplefile {knuth-gpt} \stopchapter \stopbodymatter \startbackmatter \startchapter [title=back1] \samplefile {knuth-gpt} \stopchapter \stopbackmatter \stoptext Does the level change message suggest that something is missing in the document? -- Rik

Font version parse question
by Rik Kabel 07 Mar '24

07 Mar '24

Hello all, The font tweak file libertinus_math.lfg tests for a font version of *7.040*, but the result of the version parse is *7.040;RELEASE*, resulting in an error message. I do not know if this is the fault of the parser or of the font metadata. Changing the test in the .lfg file fixes the error, but that is not a long-term solution. The exact message I get in the log is: mathematics > tweak > 'LibertinusMath-Regular', size 10, math size 0, version 'Version, 7.040;RELEASE' found, version 'Version 7.040' expected This is not a high-priority issue for me -- I have nothing in this document that would benefit -- but others may appreciate a fix. -- Rik

imposition: getting to the last page of a booklet
by Michael Guravage 07 Mar '24

07 Mar '24

Greetings, I would like to use the nextquadruple and beforequadruple pagebreakhandlers described at the bottom of the wiki's imposition page. However, the examples complain of an error invoking the \installpagebreakhandler command. The wiki page was last updated nearly four years ago. Is anyone using updated versions of these? -- With kind regards, Michael

multicolumn title and abstact (bachotex) using tugboat.mkxl
by damien＠thiriet.web4me.fr 07 Mar '24

07 Mar '24

Hello, I am currently writing my paper for last year's BachoTeX proceedings. I am using tugboat.mkxl module to design the layout. In bachotex proceedings, the author's data and abstract are on a single column and the article is usually typeset on two columns. Comments in tugboat.mkxl states: %D We have several column mechanisms and they all serve a different purpose. Here we %D use pagecolumns. They support much of what we can do in single columns, but of %D course there are exceptions. Floats can go into columns of aremoved to the top or %D bottom when there is no room. We don't span mid column. Notes can go in columns %D or at the end. We can start with a single column (for titles and such). I can't figure out which part of the file should be used/adapted to start with a single column. What I did is to put datas and abstract in a frame and use \placefigure. As stated in pagecolumns manual, everything is put on the top of next page. (BTW, there is a typo: «of aremoved») I don't know, whether this MWE helps is relevant, but just in case, here is what I did: * copy tugboat.mkxl to a new file p-bachotex.mkxl * changed p-bachotex.mkxl like this: \startsetups bachotex:naglowek:columns \defineframedtext [Dane] \setupframedtext [Dane] [width=18cm , align=normal, frame=no] \definenarrower [Streszczenia] [2*middle] \startplacefigure [location={here,none}] {\startDane {\tfa\getvariable{tugboat}{author}}\par \getvariable{tugboat}{address}\par {\tt\getvariable{tugboat}{email}}\par \startStreszczenia \doifelsebufferempty {abstract} { % no abstract } { \blank[line] \enforced\let\\\endgraf \setups[tugboat:abstract:setup] \startAbstracts[title={Abstract}] \stopAbstracts } \stopStreszczenia \stopDane} \stopplacefigure \stopsetups \startsetups tugboat:article:start \starttext \setups{tugboat:columns:presets} \setups{tugboat:banner:setup:\getvariable{tugboat}{type}} \setupheadertexts [\setups{tugboat:banner:text:article}] [pagenumber] \setuppagenumber [number=\getvariable{tugboat}{page}] \startmode[columns] \startpagecolumns \stopmode \setups[tugboat:introduction:article] \doifmodeelse{columns}{ \setups{bachotex:naglowek:columns} } { \setups{bachotex:naglowek:nocolumns} } \stopsetups My article begins so: \enablemode [columns] \usemodule [bachotex] % skipped tugboat variables for this MWE \StartAbstract \input tufte \StopAbstract \StartArticle \input knuth \StopArticle Thank you for your help Damien T

\showsymbolset is noop
by Henning Hraban Ramm 06 Mar '24

The \showsymbolset has no output any more, apparently already for some time. I checked on COW (ConTeXt ver: 2022.12.22 22:17 LMTX fmt: 2022.12.23) and my local installation (ConTeXt ver: 2024.02.22 18:31 LMTX fmt: 2024.2.22). Can someone try on MkIV?

.jpx and .jxl
by Jim 05 Mar '24

05 Mar '24

Recently I've been trying to make some PDFs smaller by using better compression of JPEG pictures. I was happy to see that \externalfigure cheerfully accepts .jp2 (JPEG 2000) files. However, my understanding (and I could well be wrong, but I've seen it multiple places) is that JPEG 2000 *Part 2* files should have extension .jpx, not .jp2. By default, ConTeXt does not recognize .jpx. But if I rename a .jpx file to have a .jp2 extension, then ConTeXt properly processes the file and I see the picture in the PDF. Q: are there any plans to make ConTeXt recognize the .jpx extension? If not, can anyone suggest some ConTeXt code which allows me to tell ConTeXt to process a .jpx file as a .jp2 file? I have also been investigating the use to JPEG-XL files (.jxl). One of the interesting aspects of JXL files is that .jpg files can be **losslessly** compressed into .jxl files. (That is, you can recover the exact .jpg from the .jxl file if you want, so there is no further degradation of the image by doing this lossless compression.) I have been seeing 20% to 30% reduction in file sizes by converting JPGs into JXLs, which I would be happy to make use of in my PDFs, if possible. Bonus question: is there any plan to support JXL files in ConTeXt? Thanks. Jim
