marginals from footnotes
by Henning Hraban Ramm 20 Oct '21

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.)

MkIV missing?
by Henning Hraban Ramm 19 Oct '21

19 Oct '21

Hi, since a while, I can’t run MkIV any more, even after several runs of install.sh (and mtxrun --generate, of course). It’s the same on my Mac and my Linux laptop (of course the bin dir is different on the latter): $ context --version mtx-context | ConTeXt Process Management 1.04 mtx-context | mtx-context | main context file: /Users/hraban/lmtx/tex/texmf-context/tex/context/base/mkiv/context.mkiv mtx-context | current version: 2021.09.26 17:00 mtx-context | main context file: /Users/hraban/lmtx/tex/texmf-context/tex/context/base/mkxl/context.mkxl mtx-context | current version: 2021.09.26 17:00 $ context --version --luatex mtx-context | redirect luametatex -> luatex: luatex --luaonly "/Users/hraban/lmtx/tex/texmf-osx-64/bin/mtxrun.lua" --script mtx-context --version --luatex --redirected mtxrun | unknown script 'mtx-context.lua' or 'mtx-mtx-context.lua' $ which context /Users/hraban/lmtx/tex/texmf-osx-64/bin/context $ which luatex /Users/hraban/lmtx/tex/texmf-osx-64/bin/luatex $ luatex --version This is LuaTeX, Version 1.13.0 (TeX Live 2021) ... $ mtxrun --version mtxrun | ConTeXt TDS Runner Tool 1.32 mtxrun | source path I thought that was related to the server/provider move, but I guess it isn’t. It’s a bit annoying that install.sh leaves ~/lmtx/bin in the PATH, so that a call to mtxrun can’t find any configuration. Hraban

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 -----------------------------------------------------------------

Error: attempt to index a nil value
by Hans Åberg 13 Oct '21

13 Oct '21

I was suggested a long ago to hack the file /usr/local/texlive/2021/texmf-dist/tex/generic/context/luatex/luatex-math.tex and use LuaTeX directly, now using Version 1.13.2 (TeX Live 2021), but I get this error: (./luaotfload.sty (/usr/local/texlive/2021/texmf-dist/tex/latex/base/ltluatex.tex)) (./luatex-math-modified.tex[\directlua]:1: attempt to index a nil value (global 'arguments') stack traceback: [\directlua]:1: in main chunk. l.132 } ? … It is from this segment in the modified luatex-math.tex: \ifdefined\directlua \directlua { if arguments["mtx:lucidabright"] then tex.print("\string\\lucidabright") else tex.print("\string\\latinmodern") end } \fi Is there a workaround? —I may ditch this setup in favour of using 'context' directly, so it is not so important if there is no fix.
