How to hide any content?
by Joel 30 Jul '24

30 Jul '24

I have a strange issue with some macros that are creating extraspaces between paragraphs. Note these macros shouldn’t create anycontent, as they define content that will be sent to registers andcontent that is used for page references. Its more like invisibledata, perhaps the word is “metadata” and other parts of thedocument need to know it and refer to it, but nothing should berendered there. As best as I canunderstand, when ConTeXt sees one of these macros, it creates avertical space after the paragraph, draws nothing, then createsanother vertical space after that, before drawing the next paragraph,so the result is something close to three lines of space. Whenappearing after a section title, its also as if there is an emptyline, then blank space, then the first paragraph of content appears. Sample of what the rendered document looks like: ----- Section Title .<--if the macro is placed here, a huge empty space after thesection title is there .<-- I’m using these dots to represent empty lines Loremipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmodtempor incididunt ut labore et dolore magna aliqua. Ut enim ad minimveniam, quis nostrud exercitation ullamco laboris nisi ut aliquip exea commodo consequat. Duis aute irure dolor in reprehenderit involuptate velit esse cillum dolore eu fugiat nulla pariatur.Excepteur sint occaecat cupidatat non proident, sunt in culpa quiofficia deserunt mollit anim id est laborum.\mymacro{}<--even ifthe macro is placed here, still in the paragraph, it creates a break . .<--the macro appears here, there is an empty space above and before . Loremipsum odor amet, consectetuer adipiscing elit. Imperdiet suspendisseporttitor tempus arcu turpis cras posuere varius. Volutpat posueresemper nunc metus fermentum egestas? Aenean diam nisl tortor fuscefacilisis hendrerit dolor penatibus. Lectus interdum platea rhoncusat leo; ut mi duis. Nisi vehicula morbi curabitur mus urna sodalessuspendisse sodales. Viverra inceptos sem aenean ultricies congueligula condimentum maecenas. Convallis in elementum risus nec tacitibibendum faucibus ac nascetur. Nulla ligula auctor placerat dignissiminceptos. Felis nulla quam viverra augue maximus hendrerit ipsum. . <--where the macro doesn’t appear, the spacing between paragraphs isfine (here, no macro, so one line of empty space, not three) Loremipsum odor amet, consectetuer adipiscing elit. Turpis himenaeosconubia neque fringilla neque class. Elementum per fermentum nostraullamcorper lacinia tortor pellentesque facilisis. Himenaeos sociosqutellus aptent rhoncus dignissim himenaeos aliquam? Nisi sagittiseuismod tincidunt penatibus eget tristique? Sed nam elit sapientellus mus libero. Consectetur nascetur nec metus pretium hacmolestie. Convallis lacinia quam efficitur convallis; metus purusaliquet. ----- I’ve analyzed themacros carefully, even rebuilt them. Yet, no matter my attempts torecreate and rewrite the code from scratch, they always create thisvertical space. They shouldn’t create any content, nor should anyevidence of their existence be visible to readers. I’ve tried formonths to find a way to hide these macros, rewriting the code itselfmany times, as I can’t see any reason why its creating anything atall, and also trying to find ways to hide the “blank” contentthat gets rendered: \starteffect[hidden]\mymacro{}\stopeffect \color[white]{\mymacro} \setbox\scratchbox=\vbox{\mymacro} \startnointerference\mymacro\stopnointerference \inmargin{\mymacro} Thesesolutions either entirely don’t remove the extra page break, orlead to the actual content within breaking: for instance, if there’san \index{} entry inside the macro, its page number won’t renderproperly in the end-of-document index. Or if there’s a \reference,other code attempting to display the page number just shows “page,??”. Isthere a way to completely hide content, such that nothing at all isrendered on the page and nothing occupies extra blank space, but thatdoesn’t brak indexes, cross-references, registers, etc.? --Joel

How can I force ConTeXt to display my footnote on the same page as my foot note marker?
by ai2472206007＠yeah.net 29 Jul '24

29 Jul '24

Hi, I have a document that contains a lot of footnotes. Therefore, I used to separate the footnote number from the footnote text, which would make the source file look more readable. Therefore, I used a similar approach to 'CASE 1', but not 'CASE 2' , placing footnotes related to the previous paragraphs every few paragraphs. But when I was generating a PDF, I found that the footnote didn't always appear on the same page as its footnote number, even though the footnote had very little text. What can I do to get my idea to work? Thanks for any suggestions. Muyik. % The above text was translated through Bing % because I am not a native English speaker. % If there is anything unclear, whatever it is, tell me. %%%%%%%%%%%%%% \setuppapersize[A6] \starttext % case 1 \input knuthmath \note[1] \input knuthmath \note[2] \input knuthmath \input knuthmath \footnotetext[1]{\input knuthmath } \footnotetext[2]{\input knuth } % In this case, the text of footnotes 1 and 2 is placed on the same page, % but they are separated from the footnote numbers on different pages \page % case 2 \input knuthmath \note[1] \footnotetext[1]{\input knuthmath } \input knuthmath \note[2] \input knuthmath \input knuthmath \footnotetext[2]{\input knuth } % Maybe this situation might get what I wanted, but after all, % footnotes are not as important as the main text, % and working on the footnotes while writing the main text may not be the right way for me \stoptext %%%%%%%%%%%%%%

correcting Wikipedia
by Pablo Rodriguez 26 Jul '24

26 Jul '24

Dear list, just by accident, I discovered that the English Wikipedia had attributed ConTeXt to https://en.wikipedia.org/wiki/Hans_Hagen (a German computer science professor). I corrected this info and also removed the internal links to that article that belong to “our” Hans (Hagen). Just in case the wording may be improved, I wrote (reprashing a previous sentence and adding two links to pages with photo): (Prof. Dr.) Hans Hagen is not to be confused with Hans Hagen, the author of the ConTeXt macro package for the TeX typesetting system.[5] [5] ConTeXt’s author comes from the Netherlands (he is a digital typographer, no academic). In any case, German Hans Hagen and Dutch Hans Hagen are clearly not the same individual. Many thanks in advance, Pablo

About a pagination

Hi, I'm trying to get the same pagination as in the attached photos. Using the wiki and Wolfgang's codes I get something interesting but not very elegant (\ACFRAME{}).

spacing in columns
by Hans van der Meer 23 Jul '24

23 Jul '24

The first screenshot has its items neatly stacked and is made with \startsimplecolumns[n=2] \placenotes[endnote] \stopsimplecolumns The second screenshot has its items wide apart and is made with \startcolumns[n=2,blank=1pt] \placenotes[endnote] \stopcolumns Question: how do I get rid of the interline space in the last case. Whatever I fill in for blank= doesn't make a difference, the output is always the same. yours sincerely dr. Hans van der Meer

Install urbanist fonts

Hello, I was trying to install the urbanist fonts (https://github.com/coreyhu/Urbanist) but I couldn't get it to load and save the fonts in the system folder and in the ConTeXt folder without success, I could only get it to load when saving them in the current working directory but that is annoying, help me by telling me the correct way to install it...

request for talk/article on writing modules
by Henning Hraban Ramm 22 Jul '24

22 Jul '24

Hi wizards, I’d really appreciate an introduction “how to write a ConTeXt module” at the meeting and in the next journal. * How does this namespace and setup stuff work? * When does it make sense to use variables, macros or parameters? * Should I use the namespace for internally used MP graphics, environments, buffers etc.? I guess I can figure out most of it on my own, but I think we should have some easily understandable documentation. Or do we already have something and I didn’t find it? I can contribute the part about distribution. Best, Hraban

How to create a second bibliography?
by Joel 22 Jul '24

22 Jul '24

My copy editor wants me to create a second bibliography for photo/illustration references. I'm using basic code to make a bibliography: \usemodule[publ-imp-sbl] \usebtxdataset[default][~/Commons/sources.bib] \setupbtx[dataset=default] \usebtxdefinitions[sbl] \setupbtx[sbl] \starttext \input knuth \cite[authoryear] \startchapter[title=Bibliography] \placelistofpublications \stopchapter\stoptext I know how to create custom lists and indexes, but not a bibliography list. How do I point the image references to go to a different list, but still its a bibliography? \startchapter[title=Image Credits] \placelistofcredits \stopchapter --Joel
