Unwanted blank page before page figures when using non-placed (hidden) heads
by cryo shock 29 Jul '22

29 Jul '22

Hey there, I am having trouble understanding some basic blank page behavior. I hope that somebody of you can point me in the right direction. My primary goal is to create application documents consisting of various .tex components and with external PDF pages inserted as well. The second part of that goal is to use multiple-level bookmarking as well. Bookmarking should look like this: - Letter - Resume - Testimonies -- Testimony A -- Testimony B -- Testimony C In the following MWE you can see my progress along with some notes to help understanding. There are two questions, I'd wish could be answered: 1. Why does TeX insert a blank page before a pagefigure I enclose within a (hidden) head? 2. Can the \bookmark[list]{text} command be somehow used for multi-level bookmarking? While the first question would make up for a more consistent solution, the second question would do the job as well. I hope some of you can enlighten me. Cheers, k %%% START of MWE \definehead[VisiSection][section] \setuphead[VisiSection][number=no] \definehead[InvisiSection][VisiSection] \setuphead[InvisiSection][placehead=no] \definelist[CustomBMarks] \setupinteraction[state=start] \placebookmarks[VisiSection,InvisiSection,CustomBMarks] \startcomponent * % not a product, no \startVisiSection[title={Custom Section A}] Text of Custom Section A \stopVisiSection \page \startVisiSection[title={Custom Section B}] Text of Custom Section B \stopVisiSection \startInvisiSection[title={Hidden Custom Section A}] Text of Hidden Custom Section A \stopInvisiSection \page \startInvisiSection[title={Hidden Custom Section B}] Text of Hidden Custom Section B \stopInvisiSection \page TEST\bookmark[CustomBMarks]{Start of Teststack} \dorecurse{800}{TEST }NEEDLE\bookmark[CustomBMarks]{Needle in the Teststack} \dorecurse{400}{TEST }TEST.\bookmark[CustomBMarks]{End of Teststack} %%% %%% So far no problems. %%% The following combination does the job, but I see no possibility %%% to arrange the "CustomBMarks"-list in multi-levels. %%% \page \startstandardmakeup \filterpages[{test.pdf}][1]\bookmark[CustomBMarks]{Pagefigure} \stopstandardmakeup %%% %%% So the following method would be the best choice to work with %%% multi-level bookmarks.

The numbered page before is the unwanted one. %%% \startInvisiSection[title={External Testpage A}] \startstandardmakeup \filterpages[{test.pdf}][1] \stopstandardmakeup \stopInvisiSection \stopcomponent %%% END of MWE

Can't no break between a close punctuation and a open punctuation
by 黄复雄 29 Jul '22

29 Jul '22

Dear Hans, I found that ConTeXt injected two infinity penalties between a close punctuation and a open punctuation, for example between `”“`, or `：“`, as showed in the following Chinese document. But actually, we need to break between them sometime. Please note that there is no space around full width punctuations in Chinese document. ```lmtx \setscript[hanzi] \usetypescriptfile[mscore] \usebodyfont [mschinese,20pt] \showframe % just for watching node list % \startluacode % local watch = require("watch_sys_actions.lua") % watch.register() % \stopluacode \starttext \dorecurse{5}{“好？！；”“：，。”} % linebreak sutck \dorecurse{30}{“我”} % linebreak sutck \dorecurse{30}{我} % linebreak work \dorecurse{30}{我。} % linebreak work \stoptext ``` What I see between any two consecutive punctuations is <penalty userpenalty> 10000 <glue userskip> 0 0 655500 <penalty userpenalty> 10000 <glue userskip> 0 655500 0 so nowhere to linebreak.

linebreak error: no leftinit or rightinit or leftfill or rigthfill expected
by 黄复雄 29 Jul '22

29 Jul '22

I mistakenly sent the following letter to luatex(a)tug.org yesterday. I hope it won't cause anyone any trouble. Thanks to luigi for pointing out the error. ------------------------------------------------- Hi all, I just updated my ConTeXt to system > ConTeXt ver: 2022.07.06 21:42 LMTX fmt: 2022.7.12 int: english/english yesterday and got a error message in using tex.linebreak(head) as follow: luatex warning > linebreak: no [ leftinit | rightinit | leftfill | rigthfill] expected I can't get any information about them. The head and the list going to tex.linebreak() like: <node : nil <= 2371 => 2873 : par vmodepar> <node : 2371 <= 2873 => 2879 : glue indentskip> <node : 2873 <= 2879 => 2891 : glyph unset> <node : 2879 <= 2891 => 2897 : glue userskip> ... <node : 636 <= 3077 => 639 : glyph unset> <node : 3077 <= 639 => 3089 : kern userkern> <node : 639 <= 3089 => 2334 : glue userskip> <node : 3089 <= 2334 => 3095 : rule normal> <node : 2334 <= 3095 => 3101 : glue spaceskip> <node : 3095 <= 3101 => 642 : glue spaceskip> <node : 3101 <= 642 => 3107 : penalty userpenalty> <node : 642 <= 3107 => nil : glue userskip> My question is: Which of them is necessary, and How can I node.new() one and Where should it go in the list? Any hint would be appreciated, Huang Fusyong(黄复雄)

barring changes
by Henning Hraban Ramm 28 Jul '22

28 Jul '22

Please consider the attached example – some of the “barring” macros are defunct already for a while, some more within a TABLE: \underbar works, but not in TABLE \underbars works \underdot doesn’t work \underdots doesn’t work \underdash doesn’t work \underdashes doesn’t work \underrandom doesn’t work \underrandoms doesn’t work \overbar works, but not in TABLE \overbars works \overstrike works, but not in TABLE \overstrikes works \understrike works, but not in TABLE \understrikes works The nested example \overbar{Über} \underbar{Unterstrich \underbar{steigt \overbar{auf} den \underdot{Unterberg}}}. works only once, afterwards all the underbars are missing.

Can't manipulate glue added by tex.preparelinebreak
by Max Chernoff 28 Jul '22

28 Jul '22

Hi Hans, The new tex.preparelinebreak is great (thanks again), but I can't seem to figure out how to manipulate the parfillskip nodes that it adds. MWE: \newbox\testbox \startluacode function test(head) if head.id ~= node.id "par" then return head end new_head = node.copylist(head) tex.preparelinebreak(new_head) local parfillskip = node.tail(new_head) inspect(parfillskip) -- Confirm that this really is a parfillskip parfillskip.stretchorder = 0 parfillskip.stretch = 0 local broken = tex.linebreak(new_head) tex.setbox("global", "testbox", broken) return head end \stopluacode \starttext {\dorecurse{209}{Hello }\par}\page {\parfillskip=0pt\dorecurse{209}{Hello }\par}\page {\ctxlua{nodes.tasks.appendaction("processors", "after", "test")} \dorecurse{209}{Hello }\par}\page \box\testbox \stoptext I would expect that pages 1 and 3 would be identical, and that pages 2 and 4 would be identical. However, page 4 is the same as pages 1 and 3, which isn't what I'd expect. I can do a similar idea in LuaTeX/MkIV and get the expected results, so I'm not too sure what I'm doing wrong here. I'm probably just missing something obvious, but I'm not too sure what. Any ideas? Thanks, -- Max

I may have misunderstood...
by jbf 27 Jul '22

27 Jul '22

Bruce, This is off-list because I see you already had an answer, but I'm wondering if I have misunderstood your problem. I thought there was a simple way to do this (or at least it is how I do it): |\setuphead [chapter] [page={yes,header,footer,right}] | Which * Finishes the last page of the previous chapter * Disables the header and footer for the next (empty) page * Adds an empty page when necessary to start the new chapter on a right page I see, too, that you have added in Wolfgang's elegant solution to an earlier issue I had with placing images on that blank page before a chapter title. That was kind of you. I've never ventured into adding to/correcting aspects of the wiki. I've often wanted to... even just to quietly fix up some of the English. It is a no-no to mention that sort of thing in the public forum, and the best way around it, I think, is to simply make adjustments here and there when it would help. Julian

french quotation marks
by Henning Hraban Ramm 26 Jul '22

26 Jul '22

Hi, according to my knowledge (and also Wikipedia), French uses « … » as double (\quotation) and ‹ … › as single (\quote) quotation marks. The current setting in ConTeXt however is « … » for both, just with less spacing for \quote. If no francophone user objects I’d suggest to fix this. Hraban \mainlanguage[fr] \starttext \quotation{\quote{Wikipédia} est un projet d’encyclopédie collective en ligne, universelle, multilingue et fonctionnant sur le principe du \quotation{wiki}.} \stoptext

Count (and limit) glyphs per line?
by Benjamin Buchmuller 26 Jul '22

26 Jul '22

Dear list, I've been confronted with the following 'intriguing' formatting requirement for a document: " • Type density: Must be no more than 15 characters per linear inch (including characters and spaces). • Line spacing: Must be no more than six lines per vertical inch. " While the line spacing resolves in ConTeXt to \setupinterlinespace[line=\dimexpr(1in / 6)] I was wondering if one can limit "type density" as the number of glyphs per inch in TeX too? I thought, it is more convenient to rephrase this request (for a 7 in textwidth) to limit the number of glyphs per line to 112. (Font must be sans or serif, of course ...) I've tried \setuplayout[width=112\averagecharwidth] which, however, results in ~120–130 characters and spaces per line. Pragmatically, I'm narrowing the text width to empirically match the requirement, but I'm nevertheless curious if there is a Lua/TeX solution to this "problem"? Thank you! Benjamin
