generic font loader + luaotfload: 'nodepool' (a nil value)"
by Ulrike Fischer 15 Jul '17

15 Jul '17

I have been trying to use the newest generic font loader (luatex-fonts-merged.lua) in the context minimals with luaotfload in latex. This mostly worked with one exception: luaotfload-letterspace.lua reference a value that no longer exists: "...mf-dist/tex/luatex/luaotfload/luaotfload-letterspace.lua:73: attempt to index local 'nodepool' (a nil value)". luaotfload does local nodedirect = nodes.nuts local nodepool = nodedirect.pool local new_kern = nodepool.kern and uses new_kern here local kern_injector = function (fillup, kern) if fillup then local g = new_glue(kern) local s = getfield(g, "spec") setfield(s, "stretch", kern) setfield(s, "stretch_order", 1) return g end return new_kern(kern) end The error goes away when I add this to the fontloader (from an older version): nuts.new=direct.new -- new UF nuts.pool={} function nuts.pool.kern(k) local n=nuts.new("kern",1) setfield(n,"kern",k) return n end -- end UF nuts.getprop=nuts.getattr But I would prefer to change luaotfload-letterspace.lua to use whatever should be used to get the correct effect. Can someone tell me how to do it?? -- Ulrike Fischer http://www.troubleshooting-tex.de/

+ssty leads to wrong parentheses with stix2math fonts.
by Ulrike Fischer 14 Jul '17

14 Jul '17

The following is a context adaption of this tex.SX question: https://tex.stackexchange.com/questions/380262/left-right-problem-with-stix… The problem is that with the stix 2 math fonts, parentheses don't grow in a font with active +ssty feature when using luatex with the context based fontloader. (With xelatex everything is fine, harfbuzz seems to do it as wanted). Below are two examples: One a mix of plain and context, and one with a (shortened) typescript definition from a posting some weeks ago. In both cases the parenthese in the second exponent is too small (I attach an image, but don't know if it will come through). Imho the source of the problem is that the font contains parenleft.ssty, parenright.ssty, parenleft.ssty2 and parenright.ssty2 glyphs and these "wins" when the fontloader is looking for variants. The glyphs are *not* in the vvariants-list of the parentheses. Other delimiters are not affected.

confusing columns balancing results
by Floris van Manen 14 Jul '17

14 Jul '17

When i try to use five balanced columns on a landscape page, i get unexpected results. \setuppapersize[A4, landscape] \setupbodyfont[8pt] \language[fr] \setupcolumns[ n=5, distance=4mm, balance=yes, tolerance=tolerant] \setupfootertexts[][] \setuplayout[ backspace=10mm, width=277mm, height=fit, topspace=10mm, header=0mm, top=0mm, footer=0mm, bottom=0mm] \setuppagenumber[state=none] \setuppagenumber[state=stop] \definelayout[WithoutMarginnotes][ location={duplex}, grid=no, topspace=1cm, height=19cm, backspace=1cm, cutspace=0cm, leftmargin=0cm, leftmargindistance=0.4cm, width=fit, rightmargindistance=0cm, rightmargin=0cm] \setuplayout[WithoutMarginnotes] \setuphead[section][ align=normal, style=\tfa\ss, before={\blank}, after={\blank[2pt]}] When using balance=no the page is properly typeset \setupcolumns[ n=5, distance=4mm, balance=no, tolerance=tolerant] When using balance=yes It looks as if the page orientation became portrait mode, as the text disappears at the bottom of the page. \setupcolumns[ n=5, distance=4mm, balance=yes, tolerance=tolerant] Some hints as how to proceed? Thanks .Floris van Manen

whitespace between endnotes
by Meer, Hans van der 14 Jul '17

14 Jul '17

\placenotes[endnote] puts a list of endnotes spaced out with the setting of \setupwhitespace. Is there a means to keep \setupwhitespace undisturbed but changing this for the endnotes alone? Some parameter to be specified in \setupnote, \setupnotation or one of its friends perhaps? Hans van der Meer

Breaking formulas

Dear List, I am not sure if the file that I have prepared to sum up some of the problems of the actual implementation of auto breaking of formulas has reached the list. This time I will send only the context file to avoid too large files. Best Mathias

lua error when --synctex is used

When I run a minimal context file with the -synctex-switch context --synctex context-test.tex then I get a lua error: lua error > lua error on line 1 in file C:/Users/XXX/Documents/tests/contexttext/context-test.tex: ...ext/tex/texmf-context/tex/context/base/mkiv/node-syn.lua:490: attempt to call upvalue 'collect' (a nil value) stack traceback: ...ext/tex/texmf-context/tex/context/base/mkiv/node-syn.lua:490: in function 'luatex_synctex_collect' [string "local nodes_references_handler = nodes.refere..."]:14: in function <[string "local nodes_references_handler = nodes.refere..."]:7> (...tail calls...) 1 >> \starttext 2 context text 3 \stoptext Without the synctex switch there is no problem. -- Ulrike Fischer http://www.troubleshooting-tex.de/

figure numbering S3, S4, S6, ...
by Thomas Möbius 13 Jul '17

13 Jul '17

Dear list, I am compiling some figures as supplementary material and would like to have figure captions follow the convention: Figure S3 Figure S4 Figure S5 ... and I need that the numbering starts with S3 instead of S1. How can I achieve this? Minimal example: \setuppapersize[A6] \setupexternalfigures[location=default] \setupcaptions[way=bytext] \placefigure {Cow} {\externalfigure[cow][width=2cm]} \placefigure {Another Cow} {\externalfigure[cow][width=2cm]}

No cross-references in scrollmode
by Andreas Becker 13 Jul '17

13 Jul '17

Hello, when I pipe a file to context, it cannot resolve references, e. g. to figures or chapters: cat source.tex | context --pipe Instead of the number, "??" is printed in the PDF document. A minimal example is: \ref[reference] \placefigure[][reference]{}{} The command line output is like this: [...] mtx-context | entering scrollmode, end job with \endThis is LuaTeX, Version 0.95.0 (TeX Live 2016/Arch Linux) system commands enabled. [...] * * *(Please type a command or say `\end') *structure > sectioning > title @ level 2 : 0.0 -> Si(111) preparation *(Please type a command or say `\end') * * * * * * * * * *references > unknown reference '[][fig:si-oxide]' [...] Kind regards, Andreas Becker
