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.

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

Any way to configure \setuphead to run a setups on the stop command?
by Bruce Horrocks 26 Jul '22

26 Jul '22

If I use \definehead [Chapter] [chapter] and then \setuphead[Chapter][...] I can specify setups to run before and after \startChapter. Is there any way to specify setups that are run before & after \stopChapter? My real problem is that I have a double-sided book with new chapters starting on a right hand page. If an extra left-hand page gets added then that extra page is blank except for the header which continues from the previous chapter. This makes the page look a bit odd and I'd rather the header was blank. I can fix this by ensuring each chapter emits a final page (to ensure the headers on the last text-bearing page of the chapter are shown) and then clearing the header temporarily using: \stopChapter\page\setupheader[state=empty] This works so I wondered if there was a way of adding it to \stopChapter ? I can edit each individual chapter file easily enough so no need to add it as a feature if it's not already available in some way. — Bruce Horrocks Hampshire, UK
