font fallbacks
by Henning Hraban Ramm 01 Aug '22

01 Aug '22

Hi, I thought I could use more than one fallback font, but as soon as I list fallbacks, they stop working. In my example, I’d like to take all missing glyphs from Segoe UI Symbols, and what’s still missing (emojis) from EmojiOneColor, preferably without specifying the exact range. Additionally, I want to replace the tilde ~ of LM Modern: """ \definefontfallback[seguiFB] [file:seguisym.ttf] [0x00000-0xFFFFF] [check=yes,force=no] \definefontfallback[emoneFB] [name:EmojiOneColor] [0x00000-0xFFFFF] [check=yes,force=no] % replace tilde in LM \definefontfallback[tildeFB] [file:seguisym.ttf] [0x0007E-0x0007E] [force=yes] \starttypescript [start] \definetypeface [start] [rm] [serif] [cambria] [default][fallbacks={seguiFB,emoneFB}] \definetypeface [start] [ss] [sans] [modern] [default][fallbacks={seguiFB,emoneFB}] \definetypeface [start] [tt] [mono] [modern] [default][fallbacks={seguiFB,tildeFB,emoneFB}] \definetypeface [start] [mm] [math] [modern] [default][fallbacks={seguiFB,emoneFB}] \stoptypescript \setupbodyfont[start,rm,12pt] \starttext \Omega\ (Omega) and \aleph\ (Aleph) \startbuffer[example] start missing characters: lmmono10-regular.otf 7 U+00327 ̧ COMBINING CEDILLA 7 U+00335 ̵ COMBINING SHORT STROKE OVERLAY 14 U+003B7 η GREEK SMALL LETTER ETA 7 U+021A9 ↩ LEFTWARDS ARROW WITH HOOK 350 U+02500 ─ BOX DRAWINGS LIGHT HORIZONTAL 98 U+02502 │ BOX DRAWINGS LIGHT VERTICAL 42 U+02514 └ BOX DRAWINGS LIGHT UP AND RIGHT 133 U+0251C ├ BOX DRAWINGS LIGHT VERTICAL AND RIGHT 154 U+02772 ❲ LIGHT LEFT TORTOISE SHELL BRACKET ORNAMENT 154 U+02773 ❳ LIGHT RIGHT TORTOISE SHELL BRACKET ORNAMENT 14 U+0278A ➊ DINGBAT NEGATIVE CIRCLED SANS-SERIF DIGIT ONE stop missing characters start missing characters: cambria.ttc 9 U+0278A ➊ DINGBAT NEGATIVE CIRCLED SANS-SERIF DIGIT ONE 9 U+0FFFD � REPLACEMENT CHARACTER stop missing characters start missing characters: cambriai.ttf 266 U+0276C ❬ MEDIUM LEFT-POINTING ANGLE BRACKET ORNAMENT 266 U+0276D ❭ MEDIUM RIGHT-POINTING ANGLE BRACKET ORNAMENT stop missing characters \stopbuffer \typebuffer[example] \startlines \getbuffer[example] {\ss\getbuffer[example]} \stoplines \tex{abra}\arg{...} \type{kadabra} \type{~~~} \stoptext """ What’s wrong?

Set up external figure for particular image type
by Thangalin 01 Aug '22

01 Aug '22

A document has a mix of SVG and PNG images. Changing the parameters for `\setupexternalfigure` affects both SVG and PNG images. Consider the following code: \setupexternalfigures[ order={svg,pdf,png,jpg}, location={local,default,global}, directory={images}, maxwidth=\textwidth, maxheight=0.4\textheight ] I'd like to change the `maxheight` option for only PNG images, such as: \setupexternalfigure[ method=png, maxwidth=\textwidth, maxheight=\textheight, ] However, this affects SVG images as well. How do you apply different external figure setups based on image type? Thank you!

The horizontal axis label of mwe below has 0.0 (showing tenths; pdf attached; filename is mwe.tex). I expected it to show -1, 0, 1, 2, 3, (integers only). Can this be formatted? % -1 1 % 0 1 % 0 2 % 1 1 % 2 1 % 2 2 % 2 3 % 2 4 % 3 1 % 3 2 \usemodule[m-graph] \startMPpage[instance=graph, offset=5mm] labeloffset:=3mm; draw begingraph(8cm,4cm); setrange(-1.5,0.5,3.5,5); picture symbol ; symbol := image(draw fullcircle scaled 5mm withcolor red;); gdata("mwe.tex", v, clearxy; glabel(symbol,v1,v2) ; ); frame.bot shifted(0,-2mm) ; autogrid(otick.bot,) shifted(0,-2mm); endgraph; \stopMPpage Thanks!

Dear list, I would like to typeset two columns with different widths and no hyphenation. The columns in the output PDF overlap: https://live.contextgarden.net/cgi-bin/result.cgi?id=JnPVEM How to make the columns non-overlapping? My attempt is below. I do not see a solution at https://wiki.contextgarden.net/Command/setupparagraphs Best regards, Marcin Ciura \mainlanguage[pl] \defineparagraphs[proposition][n=2,align=nothyphenated] \setupparagraphs[proposition][1][width=0.56\textwidth] \setupparagraphs[proposition][2][width=0.41\textwidth] \starttext \startproposition Jeśli w trójkącie $ABC$ pole kwadratu skonstruowanego na jednym boku jest równe sumie pól kwadratów skonstruowanych na dwóch innych bokach: $BC^2 = AC^2 + AB^2$, to kąt $BAC$ między tymi dwoma bokami jest prosty. \proposition Jeśli odcinek stykający się z innym odcinkiem tworzy z~nim dwa równe kąty przyległe, to oba kąty przyległe nazywamy {\bf kątami prostymi}, a~o~obu odcinkach mówimy, że są {\bf prostopadłe}. \stopproposition \stoptext

Unwanted blank page before page figures when using non-placed (hidden) heads
by cryo shock 30 Jul '22

30 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
