\rotate[rotation=270] adds extra vertical space
by Pablo Rodriguez 22 Oct '21

Dear list, I have the following imposition sample: \startbuffer[newbuff] \showframe\showgrid \setuppapersize[A3, landscape] \setuplayout[width=middle] \starttext \dorecurse{4}{\null\page} \stoptext \stopbuffer \startmode[*first] \savebuffer[newbuff][A3page.tex, prefix=no] \executesystemcommand{context --purgeall A3page.tex} \stopmode \showframe \setuplayout[page] \setuppapersize[A5][A4, landscape] \setuparranging [2UP] \setupinteractionscreen[option={landscape, paper}] \starttext \doiffile{A3page.pdf} {\def\Doc{A3page.pdf} \getfiguredimensions[\Doc] \dorecurse{\noffigurepages} {\ifodd\recurselevel \rotate[rotation=90] {\externalfigure[\Doc][page=\recurselevel, width=\textheight]} \else\rotate[rotation=270] {\externalfigure[\Doc][page=\recurselevel, width=\textheight]} \fi}} \stoptext I’m afraid that if rotation values are 270 or 180, the imposed page has an extra vertical space before. I think this might be a bug. Or I don’t know what I might be missing. Many thanks for your help, Pablo -- http://www.ousia.tk

mp-geo Metapost package with ConTeXt
by Gavin 22 Oct '21

22 Oct '21

Hello ConTeXters, I’d like to use the mp-geo Metapost package with ConTeXt to draw simple globes viewed from various directions. The package is here: https://melusine.eu.org/syracuse/poulecl/mp-geo/ It looks like the last update was 2008 and I don’t read French, so I though my chances of getting anything to work were pretty small. However, I was pleasantly surprised that this MWE found the mp-geo package, the necessary Metapost files in the ConTeXt installation, and the data files. \starttext \startMPcode input mp-geo; figure(-10u,-10u,10u,10u); Mercator(3,48,30); fin; end \stopMPcode \stoptext While all of the files were found, it did not produce a globe. Instead I got an error complaining about an invalid character in the data files. This error is repeated for about 20 files (a small fraction of the total). I put the first error and its data file below. All the others are identical with different .dat files. Maybe it’s just an encoding mismatch or a hidden character I can easily delete or replace. On the other hand, maybe I shouldn't even be attempting this? 2008 is a long time ago in ConTeXt time. Feel free to tell me this project is crazy, but if you have an idea how I can make this work, I’d really appreciate it! It looks like a fun package. Thanks! Gavin Error Log: (This error log below is actually from running Metapost directly on just the .mp file with the metapost code above. This error log is slightly more clear in its formatting than the ConTeXt log, but contains the same information.) !

Indentation inside \framed won't go away
by Ramkumar KB 21 Oct '21

21 Oct '21

Hello, I have this nagging issue of indentation (in the 1st line) showing up inside \framed in spite of all the commands to skip indentation (see attached PDF). It appears that *\setupindenting[no]* is not playing any role here and some other parameter is overriding this. Any tips would be appreciated. best regards, Ramkumar \definepapersize[a4-portrait][A4][A4] \setuppapersize[a4-portrait] \setuplayout [topspace=10mm,backspace=15mm,header=50pt,footer=50pt,textwidth=165mm,height=middle,width=middle] \starttext \offset[x=\dimexpr11mm\relax,y=\dimexpr23mm\relax] {\framed[frame=on,offset=none,align=flushleft] { % \startparagraph[align=high] \setupindenting[no] Chief Vitalstatistix\\ Getafix\\ Dogmatix\\ Asterix\\ Obelix\\ } } \stoptext

precedence of texmf trees
by Henning Hraban Ramm 20 Oct '21

20 Oct '21

Hi wizards, if I have files with the same name in several texmf trees (e.g. texmf-context, texmf-local, texmf-project, ~/texmf or TeX Live’s texmf-dist, texmf-var), which one will be used? I guess “local” trees or “local” directories take precedence over “distribution”, but which is “the localest” of ~/texmf/..., texmf-dist/.../local, texmf-local/... ? Where is the order defined? (Not in TDS.) Hraban

Add ssty to libertinus
by Mikael Sundqvist 20 Oct '21

Hi, looking at the output of \setupbodyfont[libertinus] %\setupmathematics[stylealternative={ssty}] \starttext %\addff{ssty} $y'=f'$ \switchtobodyfont[newcomputermodern-book] $y'=f'$ \stoptext I think that the primes in libertinus are too small. Indeed, looking in the font, they look like the output. In lualatex* I get larger primes, and as far as I understand it is because unicode-math enables ssty. I was not able to do so with \addff{ssty} or with \setupmathematics[stylealternative={ssty}]. What do I miss? Best regards, Mikael *The file I used in lualatex was this: \documentclass{article} \usepackage{fontspec} \usepackage{unicode-math} \setmathfont{LibertinusMath-Regular.otf} \begin{document} $u'f'$ \end{document}

marginals from footnotes

20 Oct '21

Hi, this is an edge case, but I tried to replicate a feature from DANTE’s LaTeX DTK style where links in the text (and also in footnotes) get a QR code in the margin. It works for me (using zint) in the running text, but not in footnotes. Actually, marginals in footnotes are never displayed. Maybe I shouldn’t expect it to work, but I’d like to have this... Is it possible? \starttext \samplefile{tufte}\inmargin{margin note} bla\footnote{footnote\inmargin{margin note from footnote}} bla \stoptext Hraban

upload
by Hans Hagen 20 Oct '21

20 Oct '21

Hi, I uploaded a new lmtx. This one is a little experimental because I removed so redundant / intermediate code still present from teh transition from mkiv to lmtx (mostly backend related). I might have missed something (not all is in the test suite) but nothing that can't be fixed easy, most has to do with the timing of definitions. But I assume users save their stable trees anyway ... (rpi bins should be in sync too.)

Reading ConTeXt metadata values into Lua
by Ramkumar KB 17 Oct '21

17 Oct '21

Hello All, I was trying to read the value of '\totalnumberofpages' into lua to do something with it. As an example, see below. Now, as I understand it, my example would not work as TeX gets the first go at this and therefore the variable 'pages' is the string '\totalnumberofpages' and not the actual value itself. And Lua cannot process this "calculation". I tried to go thru the manual - *cld-mkiv.pdf *- in the distro but could not catch on how to read a metadata value (not print). I am sure that I am missing a small trick somewhere (or is it something more involved?). \startluacode function myFancyCalculations(pages) -- some fancy stuff but as an example local myCal = tonumber(pages) + 1 return myCal \stopluacode \starttext \blah \ctxlua{context(myFancyCalculations("\\totalnumberofpages"))} \stoptext Thank you in advance for any tips. best regards, Ramkumar

new upload
by Hans Hagen 14 Oct '21

14 Oct '21

Hi, This midweek upload has something new. There has been some discussion about footnotes and one thing I noticed when playing with some new possibilities is that the stretch in topskip (we use a default amount that long ago was derived from plain tex and is relative to the body font size) influences the pagebreaks in relation to inserts (footnotes) in a more significant way than one would expect. I also noticed that this stretch component is one of the reasons why sometimes a side float shape will carry over to a next page in spite of there being room. This relates to \brokenpenalty. At the end of this mail are some tests that demonstrate this. As a consequence we now have a "ntop" parameter as well as a shaping related penalty primitives (parameters): \shapingpenaltiesmode"FF % set all (future) bits (currently 4) \shapingpenalty\plushundred % don't go too high which is currently not enabled by default but might be in upcoming versions; this also depends on user feedback. It's a non intrusive extension the LuaMetaTeX engine. I have this setting in my local preferences file. Hans % test code (for Massimiliano and Hraban to play with) \starttext \showframe % this is the current default behaviour; we have a topskip with % quite some stretch and that stretch is taken into account % when tex calculates the badness; watch the next page \dorecurse{4}{ \bgroup \shapingpenaltiesmode\zerocount \showmakeup[penalty] \placefigure[left]{}{} \input tufte \par \egroup } \page EMPTY \page % the ntop is new and when >= 0 it is a multiplier for the number % of lines stretch, here we have one line; watch the next page \dorecurse{4}{ \bgroup \shapingpenaltiesmode\zerocount \setupinterlinespace[ntop=1] \showmakeup[penalty] \placefigure[left]{}{} \input tufte \par \egroup } \page EMPTY \page % these shaping parameters will discourage a linebreak within a % shape; the placement macro checked available space but that % doesn't mean that there can be no linebreak \dorecurse{4}{ \bgroup \showmakeup[penalty] \shapingpenaltiesmode"FF\relax \shapingpenalty\plushundred \placefigure[left]{}{} \input tufte \par \egroup } \page EMPTY \page % the next pages show the effect of changed topskip on page breaks % with footnotes \dorecurse{10}{ [#1] \input tufte \footnote{\input{tufte}} \par } \page EMPTY \page \setupinterlinespace[ntop=2] \dorecurse{10}{ [#1] \input tufte \footnote{\input{tufte}} \par } \page EMPTY \page \setupinterlinespace[ntop=0] \dorecurse{10}{ [#1] \input tufte \footnote{\input{tufte}} \par } \stoptext ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | www.pragma-ade.nl | www.pragma-pod.nl -----------------------------------------------------------------

setuplocalinterlinespace not affecting the whole group?

Hi, I have this MWE: %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% \definebodyfontenvironment [9bp] [ normal=9bp, b=24bp, ] \setupbodyfont[9bp] \startTEXpage { \setuplocalinterlinespace[line=25.5bp] %\setupinterlinespace[line=25.5bp] \tfb One\crlf Two Three } \stopTEXpage %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% For some reason \setuplocalinterlinespace[line=25.5bp] seems to affect only the first paragraph in the group, but not the distance between the two paragraphs. Using \setupinterlinespace instead of \setuplocalinterlinespace gives the same result. (Adding a \crlf between Two and Three gives the correct visual appearance. But that's an ugly hack of course...)

Now is a good time to update your LMTX installation, since the current version (October 10th) works well in many regards (esp. footnotes).

Thank you, Hans! That doesn’t mean I’ll stop complaining about stuff I would like to behave differently, of course ;) Hraban

Converting LaTeX math to ConTeXt
by Jason Ross 13 Oct '21

13 Oct '21

Hello, I'm trying to provide more support for LaTeX math for an Org Mode exporter for ConTeXt. LaTeX is the de facto standard for mathematics in Org Mode. However, the syntax is quite different between LaTeX and ConTeXt. I have a few ideas, but none that I'm happy about. 1. Export LaTeX to MathML then import that into ConTeXt. I don't know how to get this to work. latexmlmath only returns the first row of `align` environments (for me anyway). Also, this would require users to install another program. 2. Typeset equations with LaTeX as standalone pages and then include them as images. This will typeset everything with LaTeX defaults. Also, either equation alignment or equation numbering will break. 3. Hack every math environment I can think of to accept LaTeX syntax (see https://wiki.contextgarden.net/LaTeX_Math_in_ConTeXt) Lots of work, lots of problems as described in the article. End-users could add their own hacks to the template preamble for cases I don't get to. 4. Manually parse and convert every LaTeX math environment to ConTeXt before exporting. Basically a non-starter. I'm wondering what's the best way to go about this. Surely others have run into the same problem? Thanks, Jason

body text and footnote space
by jbf 12 Oct '21

12 Oct '21

Dear list, I note previous discussions on the matter of body text invading footnote space (as late as last year). As I am currently typesetting a 400 plus page academic text with hundreds of footnotes, and do not have the option of making them endnotes, I am facing this issue page after page. The only solution I have for now is to make per page layout adjustments to reduce a line or two, so there is a way to handle it, but given ConTeXt's 'perfection' generally, I would be very interested to know if there is any other solution forthcoming. I've tried various options in \setupfootnotes and \setuptolerance', but to no avail. Julian

Outlined text (from MP) inline in ConText has incorrect baseline (i.e. no depth)
by Rudd, Kevin 12 Oct '21

12 Oct '21

Hey--- I'm trying to insert outlined text (derived from MetaFun example code) into a document and it seems to work up to the point that the text has depth (descenders). There's a previous post that mentions using textcommand for titles to ensure that the appropriate baseline is used but I haven't figured out why that would work; for my purposes, I'm insert the text inline so that solution wouldn't work here. I have included a MWE that demonstrates the problem; I've tried putting both the text and the outlined text in a box, then adjusting the outlined text by the depth of the text itself but that doesn't seem to work. I expect that there's an easy way either in MP or ConTeXt, but I haven't found it yet. %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% % \OutlinedText[glyph][outline]{text} \def\OutlinedText{\dodoubleempty\doOutlinedText} \def\doOutlinedText[#1][#2]#3% {% % ((((\type{#1}::\type{#2}::\type{#3})))) \ifsecondargument \makeOutlinedText{#1}{#2}{#3}% \else\iffirstargument \makeOutlinedText{#1}{black}{#3}% \else \makeOutlinedText{white}{black}{#3}% \fi\fi } \def\makeOutlinedText#1#2#3% {% \startMPcode draw outlinetext.b("#3") (withcolor "#1") (withcolor "#2" withpen pencircle scaled 1/16); \stopMPcode \autoinsertnextspace } \starttext start \OutlinedText{aaa} and \OutlinedText{Bbb} and \OutlinedText{ggg} and \OutlinedText{Yyy} finish \stoptext %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% (Here is the code with my attemps to shift the baseline; the \dp & \wd approach seems to do nothing, and the \lower doesn't compile and I haven't pursued why yet.) %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% % \def\makeOutlinedText#1#2#3% % {% % \newbox\tBox % \newbox\uBox % \setbox\tBox\hbox{#3} % \setbox\uBox % \hbox{% % \startMPcode % draw outlinetext.b("#3") % (withcolor "#1") % (withcolor "#2" withpen pencircle scaled 1/16); % \stopMPcode % }% % % \lower\uBox\dp\tBox % \ht\uBox=\ht\tBox % \dp\uBox=\dp\tBox % \unbox\uBox % \autoinsertnextspace } %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% Any feedback or suggestions would be appreciated. ---K Kevin W.

combination with lua
by Adam Reviczky 12 Oct '21

12 Oct '21

Hi, I am trying to use a combination figure with luacode (both with latest MKIV and LMTX). However, the figures do not line up in the grid of the combination. I get the correct result with examples 1 and 2 below, but example 3 using lua functions for combination and externalfigure is what I wanted to use in the first place. MWE: \starttext \startluacode -- Combination 1 context.startplacefigure({title = "Figure"}) context.startcombination({nx = "2", ny = "2"}, "\\externalfigure[cow][width=50mm]","Caption 1", "\\externalfigure[cow][width=50mm]","Caption 2", "\\externalfigure[cow][width=50mm]","Caption 3", "\\externalfigure[cow][width=50mm]","Caption 4" ) context.stopcombination() context.stopplacefigure() -- Combination 2 context.startplacefigure({title = "Figure"}) context.startcombination({nx = "2", ny = "2"}, "Picture 1","Caption 1", "Picture 2","Caption 2", "Picture 3","Caption 3", "Picture 4","Caption 4" ) context.stopcombination() context.stopplacefigure() -- Combination 3 context.startplacefigure({title = "Figure"}) context.startcombination({nx = "2", ny = "2"}, context.externalfigure({"cow"},{width = "50mm"}),"Caption 1", context.externalfigure({"cow"},{width = "50mm"}),"Caption 2", context.externalfigure({"cow"},{width = "50mm"}),"Caption 3", context.externalfigure({"cow"},{width = "50mm"}),"Caption 4" ) context.stopcombination() context.stopplacefigure() \stopluacode \stoptext Any hints on what I am doing wrong in example 3?

Clickable url problem with \useurl and \url
by Rik Kabel 12 Oct '21

12 Oct '21

Hello List, I notice an inconsistency in the clickable area when using \useurl. With the following example, both the \from and the \url are clickable in some lines (as noted iin the value of \from) but in others, the \from is clickable but not the \url. It does seem sensitive to the urlL, but I cannot see a pattern. Example: \setupinteraction [state=start] \useurl[earlBA] [https://www.bartleby.com/sv/welcome.html] [] [Not clickable] \useurl[earlPD] [https://www.perseus.tufts.edu/hopper/] [] [Not clickable] \useurl[earlWC] [https://www.worldcat.org/] [] [Not clickable] \useurl[earlFC] [https://www.futilitycloset.com/] [] [Not clickable] \useurl[earlQU] [http://www.quote-unquote.org.uk/] [] [Not clickable] \useurl[earlAL] [https://www.aldaily.com/] [] [Not clickable] \useurl[earlTL] [http://stephanus.tlg.uci.edu/] [] [Not clickable] \useurl[earlQI] [https://quoteinvestigator.com/] [] [Clickable] \useurl[earlLH] [https://languagehat.com/] [] [Clickable] \useurl[earlSF] [https://stancarey.wordpress.com/] [] [Clickable] \starttext \from[earlLH] (\url[earlLH]) \par \from[earlQI] (\url[earlQI]) \par \from[earlFC] (\url[earlFC]) \par \from[earlWC] (\url[earlWC]) \par \from[earlQU] (\url[earlQU]) \par \from[earlAL] (\url[earlAL]) \par \from[earlSF] (\url[earlSF]) \par \from[earlBA] (\url[earlBA]) \par \from[earlPD] (\url[earlPD]) \par \from[earlTL] (\url[earlTL]) \par \stoptext Should I use something other than \url[earlXX] here to get the clickable literal url from useurl? -- Rik Kabel

Unusual error with \doifinstring in \startbtxrenderingdefinitions ... \stopbtxrenderingdefinitions
by Joey McCollum 12 Oct '21

12 Oct '21

Hi, I'm trying to define concise biblatex-style citation macros for a custom bibliographic style specification with support for intelligent placement of trailing punctuation, and I've encountered an unusual error. If I try to define the macros within the btxrenderingdefinitions environment, then the code for handling trailing punctuation with the \doifinstring and \doifnotinstring macros fails in some cases. Specifically, it correctly detects when the trailing punctuation is a period, comma, or semicolon, but not when it is a colon, exclamation point, or question mark. The following MWE reproduces the error: ``` \startbtxrenderingdefinitions[myspec] \def\autopuncttest#1#2{% \removeunwantedspaces% \doifinstring{#2}{,.!?;:}{#2}% \footnote{#1}% \doifnotinstring{#2}{,.!?;:}{#2}% } \stopbtxrenderingdefinitions \usebtxdefinitions[myspec] \starttext This works \autopuncttest{Footnote 1}, as does this \autopuncttest{Footnote 2}; and so does this \autopuncttest{Footnote 3}.\blank But this one fails if defined in the bib spec \autopuncttest{Footnote 4}!\blank And why does this one fail in the bib spec too \autopuncttest{Footnote 5}?\blank \stoptext ``` Everything works as expected if the macro definition is outside of the btxrenderingdefinitions environment. But within the environment, do certain punctuation marks need to be escaped in the second argument of \doifinstring? Or is this a bug? Joey

Re: [NTG-context] Making metafun pictures fainter (shading, uncolored clash)
by Gavin 11 Oct '21

11 Oct '21

Hi List, I made good progress producing fainter pictures in metafun. Here is a uniformly accelerated cow in the style of my book. I abandoned transparency, since I actually don’t want to see through anything. I am using uncolored to get the fade. It works great with a picture that is made with fill and draw, but it doesn’t work with shading. The example below has a flat disk and a round ball. The disk looks fine, but the shaded ball is not surviving the application of inverted / uncolored. \startMPinclusions picture disk, ball; disk := image( fill fullcircle scaled 1cm withcolor .4white; draw fullcircle scaled 1cm withpen pencircle scaled 0.8pt ;); ball := image( fill fullcircle scaled 1cm withshademethod "circular" withshadecenter (.25,.25) withshadecolors (.8white, black); draw fullcircle scaled 1cm withpen pencircle scaled 0.8pt ;); \stopMPinclusions \startMPpage draw inverted (disk uncolored .1white) ; draw inverted (disk uncolored .2white) shifted (0.25cm,0) ; draw inverted (disk uncolored .5white) shifted (1cm,0) ; draw disk shifted (2.25cm,0) ; draw inverted (ball uncolored .1white) shifted (0, -2cm) ; draw inverted (ball uncolored .2white) shifted (0.25cm, -2cm) ; draw inverted (ball uncolored .5white) shifted (1cm, -2cm) ; draw ball shifted (2.25cm, -2cm) ; \stopMPpage Same result in LMTX and MkIV. (ConTeXt ver: 2021.09.17 10:01 LMTX fmt: 2021.9.21 int: english/english) I’m pretty happy with this uncolored trick, and will be even happier if I can get it to work with the shadings. Any suggestions? Gavin

Short forms and abbreviations in bibliography
by Joey McCollum 11 Oct '21

11 Oct '21

Hi, It is a common practice to use short forms of titles for bibliographic entries after they are cited the first time. Another practice is to use abbreviations for journal names and book series (generally for citations in the text, but possibly also in the references list), with a separate "List of Abbreviations" provided to cross-reference the abbreviations and full names. I think that these practices could be accommodated with multiple bibliographies that contain short and long forms for corresponding entries, but I wanted to ask: is there a simpler or preferred way to do this in ConTeXt? To illustrate what I mean, the biblatex-sbl package ( https://github.com/dcpurton/biblatex-sbl) which implements the SBL citation style for (Xe)LaTeX, handles this using additional fields like "shorttitle," "shortjournal," and "shortseries," so for the BibTeX-style bibliographic entry @book{Blau2010, author = {Joshua Blau}, title = {Phonology and Morphology of Biblical Hebrew}, shorttitle = {Phonology}, series = {Linguistic Studies in Ancient West Semitic}, shortseries = {LSAWS}, volume = {2}, location = {Winona Lake, IN}, publisher = {Eisenbrauns}, year = {2010} } the initial in-text citation (in SBL style) would look something like Joshua Blau, *Phonology and Morphology of Biblical Hebrew*, LSAWS 2 (Winona Lake, IN: Eisenbrauns, 2010), while subsequent in-text citations would look like Blau, *Phonology*. A separate list of abbreviations would then list "LSAWS" alongside "Linguistic Studies in Ancient West Semitic" (and likewise for other journal/series abbreviations). Thank you! Joey

SyncTeX does not work with Zathura
by Cezary Drożak 11 Oct '21

11 Oct '21

Hello, I have been trying to get SyncTeX to work with ConTeXt and Zathura, but nothing seems to work. I created a simple `hello.mklx` file and ran `context --synctex=-1 hello.mklx`. Then I launched Zathura with `zathura -x "nvr -cc \"call vimtex#view#reverse_goto(%{line}, '%{input}')\" --nostart" hello.pdf`. When I clicked "Hello, world!" while holding a control key it printed the following error to console: ``` (org.pwmt.zathura:80241): GLib-CRITICAL **: 15:49:12.359: g_variant_new_string: assertion 'string != NULL' failed warning: Failed to obtain data via SyncTeX or data is incomplete. ``` I am attaching the `hello.mklx`, `hello.pdf` files and the generated `hello.synctex` file. I am getting the same result with `--synctex=1`. Regards, Cezary Drożak

Making metafun pictures fainter
by Gavin 10 Oct '21

10 Oct '21

Hi list, I’m trying to produce figures like this, showing motion as a series of snap-shots, with the earlier moments more faint. Here are three examples of metafun code using transparency and “decorated". \startMPinclusions picture ball; ball := image( draw fullcircle scaled 1cm withshademethod "circular" withshadecenter (.25,.25) withcolor "lightgray" shadedinto black; draw fullcircle scaled 1cm withpen pencircle scaled 0.8pt;); \stopMPinclusions \starttext \startMPpage draw decorated (draw ball) withtransparency (1,.2); draw decorated (draw ball shifted (1cm, 0cm)) withtransparency (1,.4); draw decorated (draw ball shifted (4cm, 0cm)) withtransparency (1,.6); draw ball shifted (9cm, 0cm); \stopMPpage \startMPpage draw decorated (draw ball) withtransparency (1,.2); draw decorated (draw ball shifted (0.25cm, 0cm)) withtransparency (1,.4); draw decorated (draw ball shifted (1cm, 0cm)) withtransparency (1,.6); draw ball shifted (2.25cm, 0cm); \stopMPpage \startMPpage draw decorated (draw ball) withtransparency (1,.2); filldraw fullcircle scaled 1cm withcolor white withpen pencircle scaled 0.8pt shifted (0.25cm, 0cm); draw decorated (draw ball shifted (0.25cm, 0cm)) withtransparency (1,.4); filldraw fullcircle scaled 1cm withcolor white withpen pencircle scaled 0.8pt shifted (1cm, 0cm); draw decorated (draw ball shifted (1cm, 0cm)) withtransparency (1,.6); draw ball shifted (2.25cm, 0cm); \stopMPpage \stoptext Transparency alone does a good job if the objects don’t overlap (first example). If they do overlap, it’s kind of a mess (second example). I get a much better result if I put a white circle behind each transparent ball so that they look lighter without showing the earlier objects through them (third example). However, that solution is going to be difficult for more complex shapes. I tried drawing the shape using “redecorated () withcolor white", to draw the white background object, but only the outline appears white. The circular shading disappears altogether, leaving the ball fill area transparent. I also tried to use something like “softened .8” but could not get that to produce any output. Any ideas? Thanks!

Default values for key-value macros
by noib3 10 Oct '21

10 Oct '21

The way I've been defining key-value macros is to first pass them to Lua, handle the parsing there thanks to `utilities.parsers.settings_to_hash` and then assign the resulting Lua table to ConTeXt variables. This worked fine up to now, but I'm having problems with the following MWE: ``` \def\style#1[#2] { \ctxlua{userdata.style([==[#2]==])} \placestyle } \startluacode userdata = userdata or {} userdata.style = function(keyvals) local style = { color = nil, text = nil, } args = utilities.parsers.settings_to_hash(keyvals) for k, v in pairs(args) do style[k] = v end context.setvariables({'style'}, style) end \stopluacode \define\placestyle{ \doiftext {\getvariable{style}{text}} {\color[\getvariable{style}{color}]{\getvariable{style}{text}}} } \starttext \style[ text={Some red text}, color=red, ] \style[ color=blue, ] \stoptext ``` Here I assign a default value of `nil` to every key, and then check if the `text` variable is empty before printing it. I would expect the second macro not to print anything since its `text` should be nil, instead both macros print 'Some red text', the first one in red and the second one in blue. I have attached a screenshot of the output. What am I doing wrong?

Hi all, I have a document here for one of my classes: xml processed via context, some layers, some two column paragraphs, a bibliography, nothing out of the ordinary. With mkiv, it compiles cleanly: mkiv lua stats > used engine: luatex version: 1.13, functionality level: 7420, banner: this is luatex, version 1.13.0 (tex live 2021) mkiv lua stats > used hash slots: 48846 of 65536 + 250000 mkiv lua stats > lua properties: engine: lua 5.3, used memory: 212 MB, ctx: 210 MB, max: unknown MB, hash chars: min(64,40), symbol mask: utf (τεχ) mkiv lua stats > runtime: 2.775 seconds, 119 processed pages, 119 shipped pages, 42.883 pages/second system | total runtime: 5.996 seconds When I compile the same document with luametatex, things slow down to a crawl: mkiv lua stats > used engine: luametatex version: 2.0921, functionality level: 20210903, format id: 594, compiler: gcc mkiv lua stats > tex properties: 740039 hash slots used of 2097152, 48372 control sequences, approximate memory usage: 36 MB mkiv lua stats > lua properties: engine: lua 5.4, used memory: 100 MB, ctx: 93 MB, max: 138 MB, symbol mask: utf (τεχ) mkiv lua stats > runtime: 27.509 seconds, 119 processed pages, 119 shipped pages, 4.326 pages/second system | total runtime: 139.458 seconds of 139.493 seconds So, it takes more than 20 times as long... The CPU of my computer goes up to 100 %, and the entire machine sometimes becomes unresponsive during the run. Obviously, I can't provide a MWE, but this seems bizarre.

But that may be a red herring. Anyway, I just wanted to report this; maybe some bigger problem (with the binary or the format?) is lurking somewhere. All best Thomas

The big problem: for the next followtext, I need the circular arc between points z[23] and z[20]. But however I place the cutbefore and cutafter, I don't get the proper part of the circle. I'm looking at the right intersection points, as the red line shows, but the blue line shows that I'm not getting the right section of the circle. How can I get this section into the path S[20]? 2. Math... :-) Is there a better way to define three circles that are at exactly the same distance than my naive "scaled 1.3" and "scaled 1.5"? 3. TeX and metafun: is there a better way to have the followtext exactly centered between the two circles rather than just fiddle with the scale factor? 4. Or is there a better approach to my problem altogether? I'm trying to reproduce an illustration from a book, so I'm very open to suggestions here. I looked at the example in the metafun manual chapter 10.4, but I'm not sure if using an overlay and multiple \followtokens would be easier. Especially since there is the scary remark "This definition is not the right one!" in this chapter without any further explanation. I hope you all had a wonderful meeting last week. I was sad I couldn't come, I was in Paris for a conference, the first after 18 months, so I couldn't skip this one. Thanks and best wishes Thomas

Addition of authortitle sorttype for bibliographies
by Joey McCollum 05 Oct '21

05 Oct '21

Hi, I've had to make another update to the general publications support code in order to implement a feature of the SBL rendering. Denis Maier has opened some issues on the context-sbl GitHub repo ( https://github.com/jjmccollum/context-sbl) to offer some helpful suggestions about needed features and bug fixes. One issue was that SBL should order list entries by author and title. Thankfully, there is already an authordate sortmethod defined in publ-aut.lua (probably to support the Chicago rendering), so I was able to use it as a template for the following authortitle sort sequence: ``` publications.sortmethods.authortitle = { sequence = { { field = "author", default = "", unknown = "" }, { field = "title", default = "", unknown = "" }, { field = "date", default = "9998-13-32", unknown = "9999-14-33" }, -- some specifications allow date instead of year, month, day { field = "year", default = "9998", unknown = "9999" }, { field = "month", default = "13", unknown = "14" }, { field = "day", default = "32", unknown = "33" }, { field = "index", default = "", unknown = "" }, }, } ``` I added this to publ-aut.lua because publications.sortmethods.authoryear is defined in that file, but if another location is more appropriate, then feel free to let me know, and I can move it! Otherwise, if this looks okay to include in a future update, then feel free to incorporate it! Joey

Dumb question about ligatures
by Bruce Horrocks 03 Oct '21

03 Oct '21

I'm using a TTF file that has no ligature capability as a built-in feature. It does however have glyphs for fi and fl but ConTeXt isn't substituting them. So the question is: what do I need to do to persuade ConTeXt to do fi & fl ligature substitution? — Bruce Horrocks Hampshire, UK

ConTeXt's equivalent of standalone class
by noib3 02 Oct '21

02 Oct '21

Coming from LaTeX, when I had some TikZ pictures I wanted to add in my document I would usually keep them on a separate file, I would compile them with the standalone class so that the resulting PDF's size would be limited to exactly the dimensions of the figure. I would then import the compiled PDF in my main document. All this to not slow down compilation times. What's the ConTeXt equivalent of this workflow? How can I keep the PDF dimensions limited to the figure?

Blank line after \item: MkIV vs LMTX and how to properly get rid of it
by Vladimir Lomov 30 Sep '21

30 Sep '21

Hello. Consider the following small example: ------------------------------------ 8< -------------------------------------- \starttext \startitemize[n] \item \input tufte \item \placefigure[right,none]{}{\externalfigure[cow]}% \input tufte \item \blank[overlay]% \placefigure[right,none]{}{\externalfigure[cow]}% \input tufte \stopitemize \startitemize[n,intext] \item \input tufte \item \placefigure[right,none]{}{\externalfigure[cow]}% \input tufte \item \blank[overlay]% \placefigure[right,none]{}{\externalfigure[cow]}% \input tufte \stopitemize \stoptext ------------------------------------ 8< -------------------------------------- I see a difference in MkIV and LMTX work: - MkIV always put a blank line despite '\blank[overlay]' command; - with \blank[overlay] and 'intext' option LMTX clutters item label (number in this case). Q1: is this the expected behavior for MkIV and LMTX? I found a recipe with \blank[overlay] in the mailing list. Q2: is it expected that LMTX will clutter item label when I use \blank[overlay]? I suspect the answer is "yes" due to the option name. Q3: how to prevent blank line insertion in such case: an item with text framing a picture (on right side or on left side but the picture is below the item label)? --- WBR, Vladimir Lomov -- Without freedom of choice there is no creativity. -- Kirk, "The return of the Archons", stardate 3157.4

At the moment \hyphenatedurl is not working for me in the latest LMTX but is in MkIV. Am I the only one experiencing this? I am aware that I am using a rather special typeface (Atkinson Hyperlegible) but am not sure if that would cause a problem... it doesn't for MkIV. Julian

special case of hskip...?
by jbf 29 Sep '21

29 Sep '21

In just one instance I would like the following to work differently: \startchapter[title={Introduction\\Disability and marginalisation},list={Introduction:\crlf Disability and marginalisation}]. That gives me: Introduction: Disability and marginalisation But I would like to have: Introduction: Disability and marginalisation Is there some way I can provide a space (whose amount I can determine specifically) after the \crlf in list={}? Effectively I am trying to provide a space at the beginning of a line, and I know I can't use \indentation or similar here. I may have to do it back at the preamble level by setting up a different kind of \setuphead, but I was hoping that in just this one case I could do it inside the existing setup. Julian

flushlayer
by Bruce Horrocks 28 Sep '21

28 Sep '21

Latest LMTX. I noticed the following \flushlayer behaviour and wondered if it was a bug or something I've misunderstood? \showframe \setuppapersize [A5][A5] \setuplayout[marking=on, location=middle] \definelayer[coverlayer] [width=\paperwidth, height=\paperheight] \setupbackgrounds [paper] [background=coverlayer,state=start ] \starttext \setlayerframed [coverlayer] [width=60mm,height=60mm,hoffset=0mm,voffset=0mm] [frame=on] {Some framed text top left of paper}% Hello world. %\flushlayer[coverlayer] \stoptext The above works as expected: the framed text is at the top left of the paper. But if I change the last three lines to: %Hello world. \flushlayer[coverlayer] \stoptext (i.e. swap around the 'commenting out') then the framed text moves to the top left of the text area not the paper. Is this intended? — Bruce Horrocks Hampshire, UK

manual hyphenation LMTX
by jbf 28 Sep '21

28 Sep '21

I may have seen a response to this at some stage in the list, but I cannot find it. \- works for manual hyphenation in Mkiv but not (for me at least) in LMTX. My general setting is \setupalign [hz, nothyphenated,stretched,verytolerant] because I am typesetting a book for visually-impaired readers using Atkinson Hyperlegible, especially developed by the Braille Foundation. In general, hyphenation is not recommended for the visually-impaired, but just occasionally it becomes necessary. Is there a reason for LMTX is not accepting \- or is there another way to achieve it in LMTX? Julian

Getting Textadept to open pdf?
by jbf 27 Sep '21

The occasional response to a similar question can be found, e.g. on stackexchange, but none of the responses work for me. Textadept is very fast at compiling (and does compile correctly). I can certainly open the pdf independently in various pdf viewers, but I cannot get Textadept to automatically open, say, Okular (installed on Linux Mint), at the end of the process. The last part of the log reads: mkiv lua stats > runtime: 0.640 seconds, 8 processed pages, 8 shipped pages, 12.492 pages/second mtx-context | pdfview methods: auto default okular pdfxcview sumatra, current method: okular (directives_pdfview_method) pdfview | command: okular --unique "test1.pdf" 1>/dev/null 2>/dev/null & mtx-context | pdfview overhead: 0.001 seconds system | total runtime: 0.649 seconds of 0.701 seconds > exit status: 0 Have tried setting up a custom text editor on okular with: /home/me/.textadept "%f" -e textadept.editing.goto_line(%l-1), as suggested by one response, but to no avail. Current version of ConTeXt is 2021.09.17 10:01 Anyone tried Textadept successfully and might have a suggestion? Julian

Hi list, The following example shows a lettrine that stylizes a quotation mark: \setuphead[chapter][ after={\placeinitial}, page=no, ] \starttext\chapter{Harriet Tubman} "Every great dream begins with a dreamer. Always remember, you have within you the strength, the patience, and the passion to reach for the stars to change the world.\chapter{Eleanor Roosevelt} Great minds discuss ideas; average minds discuss events; small minds discuss people.\stoptext Without changing the text itself, how would you make the lettrine stylize the E in Every while making the quotation mark retain the body font (i.e., much smaller and hang to the left, possibly protruding into the margin)? For reference: https://tex.stackexchange.com/q/609544/2148 Thank you!

new upload: --secure and 'dk' unit
by Hans Hagen 26 Sep '21

26 Sep '21

Hi, I uploaded a new version. The lmtx installer should now accept --secure (but one has to update the installation script) in which case curl is used when available on the system. There are no other chnages apart from the outrcome of an 'extension evening session' we had last week: /*tex We support the Knuthian Potrzebie cf.\ \url {https://en.wikipedia.org/wiki/Potrzebie} as |dk| unit. It was added 2021-09-22 exactly when we crossed the season during a evening session at the 15th \CONTEXT\ meeting in Bassenge (Boirs) Belgium. It took a few iterations to find the best numerator and denominator, but Taco Hoekwater, Harald Koenig and Mikael Sundqvist figured it out in this interactive session. The error messages have been adapted accordingly and the scanner in the |tex| library also handle it. One |dk| is 6.43985pt. There is no need to make \METAPOST\ aware of this unit because there it is just a numeric multiplier in a macro package. From Wikipedia: In issue 33, Mad published a partial table of the \quotation {Potrzebie System of Weights and Measures}, developed by 19-year-old Donald E. Knuth, later a famed computer scientist. According to Knuth, the basis of this new revolutionary system is the potrzebie, which equals the thickness of Mad issue 26, or 2.2633484517438173216473 mm [...]. */ This is a follow up of a suggestion by Hraban (on the meeting attendents list): a new unit. We have 'sp' for an unscaled unit (kind of the internal one, also used at the lua end), 'ex', 'em', 'px' as relative units (the handy ones), 'mu' for math (sort of relative and adaptive too), which leaves 'cm', 'mm' (popular and valid SI), 'pt' (natural to typesetting), 'bp' (related to postscript and pdf, the unit that competing-to-tex programs use), 'dd' and 'cc' (for Tomas Hala), 'in' (for stubborn non SI users) and now also 'dk' (for Don Knuth fans). So, Hraban (who organizes next year meeting) can now do: \setupbodyfont[dejavu,1dk] \starttext 1dk = \the\dimexpr1dk = \the\dimexpr2.2633484mm {\definedfont[Mono*none @ 6pt]test} {\definedfont[Mono*none @ 1dk]test} \stoptext And in case one wonders: this few line addition doesn't harm performance.

Ibid. and idem support for bibliographies (and variable scope more generally)
by Joey McCollum 21 Sep '21

21 Sep '21

Hi, I've found a way to implement ibid. and idem support in the SBL specification under development at https://github.com/jjmccollum/context-sbl (this e-mail essentially repeats my comments in https://github.com/jjmccollum/context-sbl/issues/5) but I'm not sure if my solution is a recommended way to solve the problem, and I'm curious about why the more straightforward approach doesn't work. I've added useibid and useidem options for the \definebtx command (making them language-dependent by adding them to mult-def.lua, which seems to be how the other options have been implemented). Ideally, I'd like to follow the pattern of the chicago:list:sameauthor setup and use a macro similar to \btxdoifsameaspreviouselse. But since \btxdoifsameaspreviouselse relies on the indexed structure of the bibliographic list to determine what the "previous" entry is, it won't work for my purposes; I need to retrieve the tag of the last entry passed to the \cite command. I ended up making this work by initializing a global variable via ``` \setxvariables[btx:sbl][previousinlinetag=\empty] ``` in the publ-imp-sbl.mkvi file, resetting it at the end of each citation via ``` \setxvariables[btx:sbl][previousinlinetag=\currentbtxtag] ``` and checking it in the appropriate places via ``` getvariable{btx:sbl}{previousinlinetag} ``` I initially tried to do this with a simple macro \btx_sbl_previousinlinetag defined in publ-imp-sbl.mkvi (in the same scope as the rest of the specification), but attempting to reset it in the cite setups with \let or \def didn't work. Why doesn't this work? Is the setup for a cite alternative executed in its own scope in a way that would prevent me from updating a variable defined in the scope of the rendering specification? And is there a way to do this that is preferable to using global variables? Thanks! Joey

Placing pagenumer with coordinates (layers)
by Huseyin Özoguz 21 Sep '21

21 Sep '21

Hello dear context-enthusiasts, I want to place the pagenumber on a double-sided project with coordinates. I tried the layer-mechanism: \setuppagenumbering[location=] \definelayer [pagenumber] [width=\paperwidth, height=\paperheight, location={left,top}, x=120mm,y=220mm, doublesided=yes] \startsetups layer \setlayer[pagenumber][even]{\pagenumber} \stopsetups \setupbackgrounds[page][setups=layer,background={pagenumber}] \starttext ~\page~\page~\page \stoptext And it works, but only for the left (even) page. On the right page I want to place the pagenumber on different coordinates. I tried to copy the layer and then change [even] to [odd] with different coordinates, but that did not work (no pagenumber printed). What do you suggest? Thank you. Huseyin

I hope it’s again only me being stupid, but when I try to update my LMTX installation or make a new one, the install script always fails with the above warning. ~/lmtx_2021-09-19 $ . install.sh mtxrun | forcing cache reload resolvers | resolving | looking for regular 'texmfcnf.lua' on given path '/Users/hraban/texmf/web2c' from specification 'home:texmf/web2c' resolvers | resolving | looking for regular 'texmfcnf.lua' on given path '/Users/hraban/texmf-local/web2c' from specification 'selfautoparent:/texmf-local/web2c' resolvers | resolving | looking for regular 'texmfcnf.lua' on given path '/Users/hraban/texmf-context/web2c' from specification 'selfautoparent:/texmf-context/web2c' resolvers | resolving | looking for regular 'texmfcnf.lua' on given path '/Users/hraban/texmf-dist/web2c' from specification 'selfautoparent:/texmf-dist/web2c' resolvers | resolving | looking for regular 'texmfcnf.lua' on given path '/Users/hraban/texmf/web2c' from specification 'selfautoparent:/texmf/web2c' resolvers | resolving | looking for fallback 'contextcnf.lua' on given path '/Users/hraban/texmf/web2c' from specification 'home:texmf/web2c' resolvers | resolving | looking for fallback 'contextcnf.lua' on given path '/Users/hraban/texmf-local/web2c' from specification 'selfautoparent:/texmf-local/web2c' resolvers | resolving | looking for fallback 'contextcnf.lua' on given path '/Users/hraban/texmf-context/web2c' from specification 'selfautoparent:/texmf-context/web2c' resolvers | resolving | looking for fallback 'contextcnf.lua' on given path '/Users/hraban/texmf-dist/web2c' from specification 'selfautoparent:/texmf-dist/web2c' resolvers | resolving | looking for fallback 'contextcnf.lua' on given path '/Users/hraban/texmf/web2c' from specification 'selfautoparent:/texmf/web2c' resolvers | resolving | resolvers | resolving | warning: no lua configuration files found resolvers | resolving | no texmf paths are defined (using TEXMF) resolvers | resolving | mtxrun | the resolver databases are not present or outdated mtx-install | provide valid server and instance cp: /Users/hraban/lmtx_2021-09-19/tex/texmf-osx-64/bin/mtxrun: No such file or directory cp: /Users/hraban/lmtx_2021-09-19/tex/texmf-context/scripts/context/lua/mtxrun.lua: No such file or directory cp: /Users/hraban/lmtx_2021-09-19/tex/texmf-context/scripts/context/lua/mtx-install.lua: No such file or directory If you want to run ConTeXt everywhere, you need to adapt the path, like: export PATH=/Users/hraban/lmtx_2021-09-19/tex/texmf-osx-64/bin:$PATH If you run from an editor you can specify the full path to mtxrun: /Users/hraban/lmtx_2021-09-19/tex/texmf-osx-64/bin/mtxrun --autogenerate --script context --autopdf ...

tabulate with lp columns
by Henning Hraban Ramm 19 Sep '21

19 Sep '21

There are some problems in the following MWEs. First example looks the same with MkIV and LMTX, second uses \NS that is only in LMTX. The first column is justified even if it’s defined as left aligned; this happens also with a simple "l" column. With "p" the width is ignored. With \NS the alignment is also wrong in the same way. \starttext \starttabulate[|lp(.2\textwidth)|lp(.2\textwidth)|lp(.2\textwidth)|lp(.2\textwidth)|] Default \NC Linux \NC MacOS \NC Windows \NC\NR \HL Text Proc \NC LibreOffice \NC Apple Pages \NC MS Office (Word) \NC\NR PDF Viewer\NC Evince \NC Preview \NC Edge \NC\NR \stoptabulate \starttabulate[|lp(.2\textwidth)|lp(.2\textwidth)|lp(.2\textwidth)|lp(.2\textwidth)|] Default \NC Linux \NC MacOS \NC Windows \NC\NR \HL Text processor \NS[3][l] LibreOffice or else \NC\NR Drawing \NS[2][lp(.4\textwidth)] Inkscape \NC Corel Draw \NC\NR Simple Editor \NC Nano \NC TextEdit \NC Notepad \NC\NR \stoptabulate \stoptext Additional question: How would I define those columns to use the whole \textwidth ?

Acrobat doesn’t display some imported metadata

improve bad habits deduplicate redundant defined values
by juh 18 Sep '21

18 Sep '21

Dear all, these are quite general questions but here they come. I defined modular styles for an organisation so that we can use different layouts with the same look and feel but still have many options to change things in a special document. I have styles for colors, fonts which are used everywhere but also styles for heads that are only used in legal context and other heads-styles used in other contexts. This works brilliant. I can even overwrite styles for one document only. I'd like to name this a cascading approach. While doing this I learned a lot and changed the way the style files are organised from time to time. Currently I start with colors and fonts. Then comes the page dimension definitions, makeups, headers and footers, headlines, the toc styles, lists and tables. Does anyone has a similar approach with a strong opinion how to organise the cascade? While working on this I often found that I defined something twice, because I forgot to delete a setup-command in a newly structured file. Is there a way to test this? Can I grep for a warning in the log files to find these duplicates?

Exclude bibliographic entries from list even when cited with \cite
by Joey McCollum 16 Sep '21

16 Sep '21

Hi, It's taken a couple weeks, but I nearly have a working bibliographic rendering for SBL style ready. I'm hosting the .lua and .mkvi files I have so far, as well as a test .bib and .tex file, on GitHub at https://github.com/jjmccollum/context-sbl. The look of the rendering seems to be correct for all of the examples, so the last remaining tasks mostly concern some lower-level technical issues. Because of the way that SBL style renders entries that are contained in other works (e.g., a chapter in a book that is part of a multivolume collection), it seemed natural to accommodate this by allowing entries to have cross-references to other entries. The rendering process can then be handled through recursive subcitations with different alternatives. In general, I handle these subcitations with the \textcite command, so that "higher-level" entries are not added to the list when they are only subcited. An important guideline that I still have to implement works in the opposite direction: it says that entries in certain categories should not be added to the list, but the books or collections containing them should be. I think I could make this work for the subcitation using the \listcite or \cite command recursively. But is there a way to conditionally handle whether or not to add the entry to the list after I invoke the \cite command, or is this built into the \cite command at a low level? If I had to, I could define an \autocite command that does all of these checks first, but if it's possible to keep the common \cite command instead of forcing users to use a different command, that would be preferable. Thanks! Joey

Number conversion in btxlist and citations
by kauśika cittūr 16 Sep '21

16 Sep '21

Dear all, I have a simple btx definition 'mylist' for which I have written a simple publ-imp-mylist.lua and publ-imp-mylist-mkvi. In that latter I have ⋮ \definebtx [mylist] [default=default,specification=mylist] \definebtxrendering [mylist] [specification=mylist] \setupbtxlist [mylist] [numberconversion=myconv] ⋮ I have define the required setups for every category entry as well. I have verified that this btxrendering works. I have also verified that my conversion set 'myconv' is functional (I am using it for page numbers and section headings). However, the numbers used in the citation are not converted. That is, 'numberconversion=myconv' seems to have no effect. What am I doing wrong? Please advise. Thanks, kauśika

Implementing a custom authorconversion for bibliographies
by Joey McCollum 15 Sep '21

15 Sep '21

Hi, I mentioned this in an earlier e-mail but thought that now might be a good time to describe this issue in detail. I'd like to define a new authorconversion that renders the first author in a list differently than the remaining authors in the list. Specifically, I'd like to use the "inverted" authorconversion for the first author and the "normal" authorconversion for the rest. In the newer bibl-bib.lua file, I can see what I might have to modify to accomplish this (I added the if combiner == "invertedfirst" block): ``` function authors.concat(author,combiner,what,settings) if type(combiner) == "string" then combiner = authors[combiner or "normal"] or authors.normal end local split = splitauthors(author) local setting = settings[what] local etallimit, etaldisplay, etaltext = 1000, 1000, "" if setting then etallimit = settings.etallimit or 1000 etaldisplay = settings.etaldisplay or etallimit etalltext = settings.etaltext or "" end local max = #split if max > etallimit and etaldisplay < max then max = etaldisplay end if combiner == "invertedfirst" then for i=1,max do if i == 1 then split[i] = authors.inverted(split[i],settings) else split[i] = authors.normal(split[i],settings) end end else for i=1,max do split[i] = combiner(split[i],settings) end end local result = bibtexconcat(split,settings) if max < #split then return result else return result .. etaltext end end ``` Unfortunately, this doesn't seem to do anything. It's not clear to me how bibl-bib.lua and bibl-bib.mkiv are being used by the other publication support modules, if they're being used at all (publ-ini.mkiv doesn't appear to register it, anyway). Is there another file I'd have to change to make "invertedfirst" a working authorconversion? Is there a similar block of code in publ-ini.lua where I should be implementing this change instead? Thanks! Joey

Changing the style of author’s surname in a custom bibliographical style
by Tomáš V 15 Sep '21

15 Sep '21

Greetings, I am trying to make a bibliographical style that would comply to the ISO 690 standard and I have a few questions: 1) The name of the author need to be written in the inverted format (e.g. Knuth, Donald). It is also customary to write the surname either in uppercase or in small caps (e.g. KNUTH, Donald). If I wanted to change the whole name to small caps I’d do something like this: \btxdoif {author} { {\sc \btxflush{author}} \btxperiod } How do I change the “font” of the surname only? Can this be done by redefining a TeX macro (like in BibLaTeX’s \mkbibnamefamily) or is this done by changing some Lua code? 2) As I have said, the name has to be inverted. This is done by setting authorconversion to inverted. I’ve tried doing this like this: \setupbtx[iso690:list][authorconversion=inverted,] and this: \setupbtxlist[iso690][authorconversion=inverted,] Neither of these options work, but this works: \setupbtx[default:list][authorconversion=inverted,] I’m confused—why does changing the default option work and changing the option for my style doesn’t? Here's a MWE for both of my problems: % publ-imp-iso690.mkiv \startbtxrenderingdefinitions[iso690] \definebtx [iso690] [ default=default, specification=iso690, ] \definebtxrendering [iso690] [ specification=iso690, numbering=yes, ] \setupbtx[default:list] [ authorconversion=inverted, ] % field definitions \starttexdefinition btx:iso690:author \btxdoif {author} { \btxflush{author} \btxperiod } \stoptexdefinition % book definition \startsetups btx:iso690:list:book \texdefinition{btx:iso690:author} \removeunwantedspaces \stopsetups % publ-imp-iso690.lua local specification = { name = "iso690", categories = { }, } local categories = specification.categories categories.book = { required = { "title" }, optional = {"author"}, } return specification Thanks for your help, Tomáš

PDF metadata and pdfx keys
by kauśika cittūr 15 Sep '21

15 Sep '21

Dear all, In my documents I use \setupinteraction [ author={AuthorName}, title={MyTitle}, subtitle={MySubtitle}, ] to set the document metadata. I also use \startluacode local metadata = lpdf.getmetadata(); metadata['producer']='author'; metadata['creator']='author'; \stopluacode to set the creator and producer. However, the document produced by ConTeXt still has the user defined keys (pdfx:) written in the metadata. I have gone through lpdf-xmp.lua, lpdf-ini.lua and back-ini.lua. Yet, I am not able to figure out how to prevent the pdfx: tags from being written. Is it possible to prevent them from being written? I prefer not to tamper with any of the ConTeXt distribution files. In this case, is there something I can do per-document to prevent these tags from being written? Please advise. Thanks, kauśika

Headline with numbers in margin doubleside layout
by juh 14 Sep '21

14 Sep '21

Hi all, I have a doubleside layout with a big outer margin. When I set alternative=margin in setuphead the chapter numbers appear in the left margin which is the outer margin on left pages, but the inner margin on right pages. While this looks good on left pages, there is much free space on right pages. I would like to use this space for headlines to balance the impression. Is it possible to assign headlines to the textarea+margin somehow only on right pages so that headlines would run into the outermargin o right pages??

update
by Hans Hagen 14 Sep '21

14 Sep '21

Hi, I uploaded a new lmtx (had forgotten to to it friday) . There are not that many visible changes but on is that i'm playing with some 'improvements' to inserts. Hopefully there are no side effects but the idea is to have somewhat better (more robust and predictable) support for e.g. footnotes in situations that are not natural to tex (like columns). The first mechanism to benefit from that is page columns but all that is a stepwise process. I keep track of that in yet another lowlevel manual. These column things are on the agenda for next month and beyond. (In a next upload the new marking and tabulate optimization might become default but for now i test that locally.)

Setting up the double pages of part beginnings
by Christian Dekant 13 Sep '21

13 Sep '21

Dear List, I am trying to set up double pages at the beginning of a new part in such a way that: - on an odd/right-hand page there will be number and the title typeset in some fashion, and - on the even/left-hand page there should be a full (printpaper)size image. If the part title ends up on an even page then there is no additional page break (but then image and title are not on the same double-page obviously). But there is a page break (and an empty left page) when the part title ends up on an odd page (when you put page=right e.g.) as in the following example: % % How to get rid of the empty page preceding a part title? % \setuppagenumbering [alternative=doublesided] \setupexternalfigures[location=default] % cow % startTEXpage does not increase page number => incrementpagenumber % trimming in the print shop => printpaperwidth/height \define[1]\FullScreen{\startTEXpage\externalfigure[#1][width=\printpaperwidth,height=\printpaperheight]\stopTEXpage\incrementpagenumber} % tried page=yes/no/right/odd \setuphead [part] [placehead=yes, page=right, before={\nowhitespace}, % ??? ] \starttext \completecontent \FullScreen{cow} \startpart[title={A nice part}] Some text ... \stoppart \FullScreen{cow} \startpart[title={A nice part}] Some text ... \stoppart \stoptext On an additional note: I would love to utilise the XML capabilities of context, so ... is the usage of \startTEpage XML-export-friendly? Anyway, best regards, thank you for your patience in advance and a happy weekend for everybody! Cheers Christian

Weird error when using \startformula inside lua
by Aditya Mahajan 12 Sep '21

12 Sep '21

I sometimes define lua functions for showing out worked out calculations. The following minimal example shows that context([[\startformula ... \stopformula]]) fails in LMTX with an error message: tex error > tex error on line 3 in file ./test.tex: Undefined control sequence \undefined MWE: \startluacode thirddata = thirddata or {} local comment = [[ This is a famous formula \startformula a^2 + b^2 = c^2 \stopformula ]] function thirddata.explanation() context(comment) end \stopluacode \starttext \ctxlua{thirddata.explanation()} \stoptext The actual use case is more complicated (where I use templates, so I don't want to convert everything to context.startformula() etc.). The example compiles with MkIV but not LMTX. Any idea what is going on? Thanks, Aditya

ConTeXt inserts additional dots for Iosevka font
by Marcel Fabian Krüger 12 Sep '21

12 Sep '21

Hi, ConTeXt has some issues with the character variant features of the Iosevka font available at https://github.com/be5invis/Iosevka/releases/download/v10.1.1/super-ttc-ios… E.g. the following document \definefontfeature [default:test] [default] [cv36=2,cv26=6] \definefont [SomeFont] [name:iosevka*default:test] \starttext \SomeFont I live in a dot-heavy world. \stoptext has six dots instead of one dot over each "i". Tests with multiple other font shapers and inspection of the font file confirmed that this is not intentional behavior. Could you take a look at that? (Based on a luotfload bug report at https://github.com/latex3/luaotfload/issues/202) Best regards, Marcel

Axis macro in MetaFun
by kauśika cittūr 12 Sep '21

12 Sep '21

Dear All, I am truly grateful for the new additions to MetaFun. It has greatly helped me in producing neat drawings for my academic work. In this connection, I have a few queries. Currently I am using PGFPlots (with ConTeXt) to draw simple plots from CSV data. I was wondering if there is any way to do the same in MetaFuns. That is, is it possible to do something like the following in order to obtain a line plot of the values in the 'data.csv' file? Also is it possible to have the 'labels' be the identical for all points in a given list? \startMPcode draw lmt_axis [ sx = 2mm, sy = 2mm, nx = 80, ny = 40, tx = 15, ty = 15, list = { [ connect = true, color = "darkblue", close = true, points = {data.csv}, labels = {"•"}, ] }, ] withpen pencircle scaled 0.5mm; \stopMPcode My final query: is it possible to specify a co-ordinate transform for any/all of the axes? For instance in my work, I would like to plot the y-axis in the log-scale. Thanks, kauśika
