balance=yes eats up footnote in one-line column
by Joey McCollum 22 Apr '20

22 Apr '20

I noticed some unexpected behavior while putting together a minimal working example for a different issue. In a multi-column layout with column balancing turned on, if the first column contains a single line and that line contains a footnote, then the footnote will not be typeset. A minimal example demonstrating this follows: \starttext \startcolumns[n=2] A single line of text with balancing.\footnote{Footnote dropped in column balancing.} \stopcolumns \stoptext I typeset this using ConTeXt version 2020.03.10 (from the TeXLive 2020 distribution). Clearly, the situation I described is an exceptional one, but it could happen in some real cases (e.g., if the last page of a two-column text consists of a widowed line with a footnote), and in any event, this seems like unintended behavior, so I thought I should bring it to the mailing list's attention.

TOC- removing Contents 0
by jbf 22 Apr '20

22 Apr '20

A simple question, but I have not found an answer to it as yet: \completecontent does everything it is supposed to, including providing the title 'Contents' on the ToC page, but it also gives me as the first line in the ToC: Contents 0 In fact the ToC appears on page 1, but regardless of the page it is appearing on, is there a way I can prevent that line from being produced as part of the ToC? I assume it would be something I need to do in the following setup: \setupcombinedlist [content] [list={chapter,section,title,subject,subsection}] \setuplist[chapter][style=normal,alternative=b, before=] Grateful for any help with this, Julian

Re: [NTG-context] animation using \startuseMPgraphic

Dear Hans, Of course, it runs so fast that it is meaningless to shorten the runtime. It is my old habit to check the algorithmic efficiency. It is just my interest. Thank you for your concern. Best regards, Dalyoung

conditional not working in \setuphead

Dear list, I have the following sample: \startbuffer[demo] <doc> <section id="section-i1"> <text>first</text> </section> <section id="section-i2"> <text>second</text> </section> </doc> \stopbuffer \startxmlsetups xml:initialize \xmlsetsetup{#1}{doc|section}{xml:*} \stopxmlsetups \xmlregistersetup{xml:initialize} \startxmlsetups xml:doc \xmlflush{#1} \stopxmlsetups \startxmlsetups xml:section \startsection[title={\xmlatt{#1}{id}}, beforesection={\doif{\xmlatt{#1}{id}}{\selectedtopic} {conditional}}] \xmlflush{#1} \doif{\xmlatt{#1}{id}}{\selectedtopic}{conditional} \stopsection \stopxmlsetups \def\selectedtopic{section-i1} \starttext \xmlprocessbuffer{main}{demo}{} \stoptext How can I make the conditional in the beforesection option work? Many thanks for your help, Pablo -- http://www.ousia.tk

animation using \startuseMPgraphic
by Jeong Dal 19 Apr '20

19 Apr '20

Dear all, I am trying to make an animation using the animation module. But it draws 10 figures instead of creating animation. Is there anything I have to do more? Or, is there a better way to do this? Thank you for reading. Best regards, Dalyoung \startuseMPgraphic{inversionPoint}{n} vardef findPointD(expr C, Q, r) = numeric dist, ang; pair X, Y; dist := r**2/sqrt((xpart Q - xpart C)**2 + (ypart Q - ypart C)**2); ang := angle(Q - C); Y := C + dir(ang)*dist; Y enddef; numeric radius, now, move; pair A,B,C,P,Q; path p,q; radius := 2cm; C := origin; p := fullcircle scaled (2*radius); z[1] = point 6 of p; z[2] = point .8 of p; q := (1.5*z1 - .5*z2) -- (-.5z1 + 1.5*z2); %q := fullcircle scaled radius shifted (2cm, 1cm); draw p; draw q; %for i := 0 step 0.1 until 1: move := 0.1; now := move*\MPvar{n}; P := point now along q; Q := findPointD(C, P, radius); drawdot P; drawdot Q withcolor .625red; dotlabel.lft(textext("P"),P); dotlabel.rt(textext("Q"),Q) withcolor .625red; %endfor; \stopuseMPgraphic \usemodule[animation] \setupinteraction[state=start] \starttext %\startplacefigure[] \startanimation[menu=yes] \dorecurse{10}{ \useMPgraphic{inversionPoint}{n=\recurselevel} } \stopanimation %\stopplacefigure \stoptext

Cannot build plain format
by Henri Menke 19 Apr '20

19 Apr '20

Dear list, I'm trying to build the plain format but it fails with $ mtxrun --script plain --make [...] ! I can't find file `luatex-plain.tex'. but mtxrun can find the file. $ mtxrun --find-file "luatex-plain.tex" /opt/context/tex/texmf-context/tex/generic/context/luatex/luatex-plain.tex What am I doing wrong? Also another question: Does LMTX come with a plain format? Cheers, Henri

Use a counter in a reference?
by Kevin Kenan 19 Apr '20

19 Apr '20

I have a need to tag elements in a text in a way that they are sequentially numbered and can have references to refer to them. Something like: Here is some \tag[tagref]{\bf text} that is tagged. . . . Refer to tag \tagnumber[tagref] on page \at[tagref]. What is the best way to do this in ConTeXt? I’ve got a counter for tag number, but I’m not sure how to use \reference so that it uses my tag number. For instance: \definecounter[myTagCounter] . . . \reference[tagref]{\rawcountervalue[myTagCounter]} Doesn’t work. But perhaps I’m going about this incorrectly? Thanks in advance! -kk

Unexpected result when using PaperHeight and MetaFUun
by Keith McKay 19 Apr '20

19 Apr '20

Dear All I have problem understanding what is happening in the MWE below which is different from what I expected. I have created a shaded background using MetaFun with dimensions PaperWidth by PaperHeight which mimics \setuppapersize[A4,landscape} as expected. I then within \starttext \startMPpage... \stopMPpage \stoptext created a stripe of the shaded background, xscaled 2cm y scaled PaperHeight, but reversed, expecting it to cover the background top to bottom. However the top of the stripe seems to start at 10.5cm which is suspiciously half the height of A4, Landscape i.e. 21cm. I confirmed this by changing the shifted command to, shifted (19cm,10.5cm), and the stripe is positioned as expected. Am I missing something obvious in how MetaFun handles coordinates? I have asumed that in MetaFun, (0,0) is the bottom left corner. Or is it how I applied the shifted command? I'm using LuaMetaTex Version 2.05.01 ConTeXt ver: 2020.04.03 10:31 MKIV beta fmt: 2020.4.6 int: english/english Thanks and stay safe. Best Wishes Keith McKay %%%%%%%%%%% MWE %%%%%%%%%%%%%%% \setuppapersize[A4,landscape] \definelayer[mybg] [x=0mm, y=0mm, width=\paperwidth, height=\paperheight] % let the layer cover the full paper \startuniqueMPgraphic{blueShade} draw lmt_shade [ path = fullsquare xyscaled(PaperWidth,PaperHeight), direction = "up", alternative = "linear", colors = { "red", "blue" }, ]; \stopuniqueMPgraphic \setlayer[mybg]{\uniqueMPgraphic{blueShade}} \setupbackgrounds[page][background={mybg}] \starttext \startMPpage StartPage ; %Result Left draw lmt_shade [ path = fullsquare xscaled 2cm yscaled PaperHeight, direction = "down", alternative = "linear", colors = { "red", "blue" }, ]shifted (12cm,0cm); %Result Right draw lmt_shade [ path = fullsquare xscaled 2cm yscaled PaperHeight, direction = "down", alternative = "linear", colors = { "red", "blue" }, ] shifted (19cm,10.5cm); StopPage ; \stopMPpage \stoptext

Question: Are there any ConTeXt aware scientific pulishers yet
by Christoph Hintermüller 19 Apr '20

19 Apr '20

Hi Jet a completely different question just out of curiosity? 1) Does anybody know of any scientific publisher or single journals which accept papers/book chapters typeset in ConTeXt yet 2) If there are any is any of them convinced enought about ConTeXt to recommend use of ConTeXt or even provide template? 3) What would be needed and what could help to make them aware? (difficult to properly formulate, if unclear dont bother) Best Xristoph -- Christoph Hintermueller Eisenhandstraße 33/23 4020 Linz Austria Tel.: +43 650 8827347 mail: christoph(a)out-world.com www: http://www.out-world.com
