\setupbackend[space=yes] and hz
by Pablo Rodriguez 22 May '21

22 May '21

Hi Hans, I have the following sample: \definefontfeature [default] [default] [expansion=quality] \setupalign [hz] \setuppapersize[A6] \setupbodyfont[pagella] \setupbackend [space=yes] \starttext \input zapf \stoptext Using SumatraPDF-3.1.2 and current latest (from 2021.05.21 15:07), spacing is only right when I disable font expansion. Would it be possible that spacing be the same with and without font expansion? Many thanks for your help, Pablo -- http://www.ousia.tk

Re: [NTG-context] mathfun (Hans Hagen)

Dear Hans, Thank you for your new module for math. If possible, I prefer to use $ \sqrt(x) = \compute\sqrt[.3N] {2} $ $ \pi = \mathexpr[.40N]{pi} $ It is more direct to use and good to write a text in which we need some math calculation. It is another good news for me. I hope it covers at least all the functions in metafun and in lua. Best regards, Dalyoung

Hand Style Sketching in Metapost
by Jeroen 21 May '21

21 May '21

I have the following working example with hatching. This works fine, but when I uncomment the sketching commands, no figure is rendered. Is the mp-sketch macro still working? \starttext \startMPcode input hatching; %input mp-sketch; %sketchypaths; %sketch_amount := 2bp; u := 1cm; path circle; circle = fullcircle scaled 4u; hatchfill circle withcolor (45, 5mm, -.5bp); draw circle; \stopMPcode \stoptext

definelabel and TEXpage
by Rik Kabel 21 May '21

21 May '21

In the following example: \definelabel[BB][alternative=inright,headcolor=red,text=] \startTEXpage Where is the label?\BB \stopTEXpage The label is not displayed if a TEXpage is used, but if the start/stop is changed to starttext/stoptext, all is well. Is this expected? -- Rik

Color problem
by Rik Kabel 21 May '21

21 May '21

Consider the following example: \define \HighlightColor {red} \definehighlight[RED][color=\HighlightColor] \definelabel[AA][alternative=inright,headcolor=\HighlightColor,text=] \definelabel[BB][alternative=inright,headcolor=red,text=] \noheaderandfooterlines \starttext \hsize3cm Is the label red?\AA Is the label red?\BB \RED{Is this line red?} \stoptext When run with --luatex, I get the colors I expect, as: When run as lmtx, I get this: All test were run with ConTeXt ver: 2021.05.20 11:08 MKIV fmt: 2021.5.20. This worked very well for a long time, then became a problem a while ago, then it resolved, and once more it is a problem. -- Rik

No kerning across discretionary nodes in latest ConTeXt upload
by Marcel Fabian Krüger 20 May '21

20 May '21

Hi, since the latest upload, ConTeXt no longer applies kerning across discretionary nodes: \starttext \setbox0\hbox{V\-a} \showboxdepth\maxdimen \showboxbreadth\maxdimen \tracingonline1 \showbox0 \stoptext used to show > \box0= \hbox(8.1915+0.25186)x13.69647, direction TLT .<1: lmroman12-regular @ 12.0pt> V .\discretionary (penalty 50) ..< <1: lmroman12-regular @ 12.0pt> - ..= \kern-0.98346 (font) .<1: lmroman12-regular @ 12.0pt> a but now changed to > \box0= \hbox(8.1915+0.25186)x14.67993, direction TLT .<1: lmroman12-regular @ 12.0pt> V .\discretionary (penalty 50) ..< <1: lmroman12-regular @ 12.0pt> - .<1: lmroman12-regular @ 12.0pt> a This seems like a regression. Best regards, Marcel

\setscript[hanzi] seems broken.
by Li Yanrui 20 May '21

20 May '21

Hi, After updating ConTeXt lmtx 2021.05.19 18:22, the line breaking with chinese characters does not work. The following is a simple example: ``` % This font can be downloaded from % https://github.com/adobe-fonts/source-han-serif/raw/release/OTF/SourceHanSe… \definefontfamily[myfont][serif][sourcehanserifcn] \setscript[hanzi] \setupbodyfont[myfont,11pt] \setuppapersize[A6][A6] \starttext 北冥有鱼，其名为鲲。鲲之大，不知其几千里也；化而为鸟，其名为鹏。鹏之背，不知其几千里也；怒而飞，其翼若垂天之云。是鸟也，海运则将徙于南冥。南冥者，天池也。 \stoptext ``` The command `context` gives the following output: Overfull \hbox (633.72849pt too wide) in paragraph at lines 7--1 <2: SourceHanSerifCN-Regular @ 11.0pt> 北冥有鱼，其名为鲲。鲲之大，不知其几千里也；化而为鸟，其名为鹏。鹏之背，不知其几千里也；怒而飞，其翼若垂天之云。是鸟也，海运则将徙于南冥。南冥者，天池也。

updating luametatex
by Alan Bowen 19 May '21

I seem to be stuck at ver. 209.08 (context ver. 2021.04.29). I downloaded context-osx-64.zip and made a clean install following the instructions for macOS on the wiki. context—version showed v. 2021.04.29 So I removed texmf cache and ran mtxrun —generate context —make context —version still showed ver. 2021.04.29 when I ran sh install.sh again, the result was the same. The version installed was still 2021.04.29 But this time the log showed an error mtx-install | running: /Users/bowen1/Desktop/LuaMetaTeX/tex/texmf-osx-64/bin/mtxrun --generate lua error : startup file: ...owen1/Desktop/LuaMetaTeX/tex/texmf-osx-64/bin/mtxrun.lua:13845: ')' expected near <eof> mtx-install | running: /Users/bowen1/Desktop/LuaMetaTeX/tex/texmf-osx-64/bin/mtxrun --script cache --erase lua error : startup file: ...owen1/Desktop/LuaMetaTeX/tex/texmf-osx-64/bin/mtxrun.lua:13845: ')' expected near <eof> mtx-install | running: /Users/bowen1/Desktop/LuaMetaTeX/tex/texmf-osx-64/bin/mtxrun --generate lua error : startup file: ...owen1/Desktop/LuaMetaTeX/tex/texmf-osx-64/bin/mtxrun.lua:13845: ')' expected near <eof> mtx-install | running: /Users/bowen1/Desktop/LuaMetaTeX/tex/texmf-osx-64/bin/context --make en lua error : function call: ...owen1/Desktop/LuaMetaTeX/tex/texmf-osx-64/bin/mtxrun.lua:13845: ')' expected near <eof> There is a problem with ver 04.21.29 that I am hoping will be fixed in a later version. So staying at ver 2021.04.29 is not ideal. Any suggestion to fix this? Alan
