LMTX crashes with source
by Pablo Rodriguez 11 Jul '21

11 Jul '21

Dear list, I have the following source: \definefontfamily [malayalam] [rm] [RIT Rachana] %~ [features=malayalam-two] \setupbodyfont [malayalam] \starttext \startTEXpage \tf അദ്ധ്യായം\\ \em അദ്ധ്യായം\\ \em\bf അദ്ധ്യായം\\ \em അദ്ധ്യായം \stopTEXpage \stoptext Using latest from 2021.07.06 18:49 and the following fonts: http://rachana.org.in/downloads/RIT-Rachana-Regular.ttf http://rachana.org.in/downloads/RIT-Rachana-Italic.ttf http://rachana.org.in/downloads/RIT-Rachana-Bold.ttf http://rachana.org.in/downloads/RIT-Rachana-BoldItalic.ttf I get a crash when using LMTX, but not with MkIV (in both Windows and Linux). I’m afraid it might be a bug. Could anyone confirm the issue? Many thanks for your help, Pablo -- http://www.ousia.tk

Ampersand in \unprotect fails in LMTX
by Marco Patzer 09 Jul '21

09 Jul '21

Hi! the following example compiles with MkIV but fails in LMTX: \unprotect \setupinteraction [\c!author={Foo & Bar}] %% {Foo \& Bar} works for MkIV and LMTX \protect \starttext\null\stoptext LMTX: 1 \unprotect 2 \setupinteraction 3 [\c!author={Foo & Bar}] 4 >> \protect 5 6 \starttext\null\stoptext 7 I can't figure out why you would want to use a tab mark here. If some right brace up above has ended a previous alignment prematurely, you're probably due for more error messages. mtx-context | fatal error: return code: 256 As \& works for MkIV as well as LMTX, there's an easy workaround. But maybe this isn't intended behaviour and needs checking. ConTeXt ver: 2021.07.06 18:49 LMTX Marco

Initial caps with short paragraph
by Thangalin 09 Jul '21

09 Jul '21

This has come up before on the mailing list, but I was wondering if LMTX has a more elegant solution than using a transparent/invisible capture of the drop-cap. Consider: \setupinitial[n=2, style=\tfd, location=text]\setuphead[chapter][after={\placeinitial}] \starttext \chapter Hello world! \input ward\stoptext The output shows that the second paragraph is not indented beyond the bounding box of the drop-cap, resulting in an overlap. This isn't a problem when the first paragraph spans two or more lines. Any ideas for how to resolve this without changing the content? Thank you!

font feature
by Thomas A. Schmitz 09 Jul '21

09 Jul '21

Hi all, is it possible to subtract a featureset that has been applied to a fontfamily? MWE: \definefontfeature [f:frac] [frac=yes,onum=no,pnum=no] \definefontfeature [f:onum] [onum=yes,pnum=yes] \definefontfamily [test] [serif] [AntykwaTorunska] [features=f:onum] \definefontfamily [test] [sans] [Myriad Pro] \definefontfamily [test] [mono] [DejaVu Sans Mono] \definefontfamily [test] [math] [Xits Math] \setupbodyfont[test,12pt] \starttext Mozarts erster Satz ist ein {\subtractfeature[f:test]\addfeature[f:frac]4/4}-Takt, Beethoven wählt einen Dreiertakt, Mozarts Romanze ist ein 3/8-Takt, Beethoven wählt einen 2/4, Mozarts Rondo ist eine Gavotte im 2/2-Takt, Beethoven schreibt ein Jagdrondo im 6/8-Takt. \stoptext If I comment out the part [features=f:onum], I get the fractions that I'm looking for, but it seems that I can't get the same effect with \subtractfeature and \addfeature. I'm confused... Thanks and all best Thomas

[OT] TeXShop v4.66 adds support for new ConTeXt's syncing method
by Nicola 09 Jul '21

09 Jul '21

For those who are interested, the latest TeXShop release provides support for ConTeXt's own syncing method (by invoking mtxrun --script synctex). This supersedes the old syncing method based on Laurens' SyncTeX, which should not be used any more. I have brought TeXShop's page in the wiki up to date (I haven't touched what are currently §1.4 and §1.5), with instructions to get synchronisation to work: https://wiki.contextgarden.net/TeXShop Make sure to read it carefully! I have tested the feature for some time now, and I'd say that it works pretty well (with some caveats, which I have annotated in the wiki). I take the opportunity to thank Hans for being so responsive with the changes in mtxrun necessary to provide this feature, and for patiently bear with my sometimes unclear requests or feedback. Kudos also to Richard Koch (TeXShop's author) for his relentless support of the macOS TeX community and, in this case, of the ConTeXt community! Happy ConTeXt'ing! Nicola

LMTX: different output if dots are used in the file name
by Marco Patzer 09 Jul '21

09 Jul '21

Hi! LMTX and MkIV behave differently if dots are used in the file name. Example: printf '%s\n' '\starttext\null\stoptext' > foo.10.tex && context foo.10.tex MkIV: → foo.10.pdf LMTX: → foo.pdf Is this intentional? This is LuaMetaTeX, Version 2.06.05 current version: 2020.05.25 23:39 Marco

xmldisplayverbatim
by Hans van der Meer 08 Jul '21

08 Jul '21

I get the impression that \xmldisplayverbatim changes ' (apostroph) into ' and " (quotation mark) into " etc. How can I get rid of this translation? I would prefer to have typeset ' and " instead of the entity representations. dr. Hans van der Meer

nuts.setfield is nil in generic code
by Michal Vlasák 08 Jul '21

08 Jul '21

Hello, in the generic font loader code `nuts.setfield` is `nil`. This is because in `luatex-basics-nod.lua` there is a wrong assignment for `nuts.setfield` on line 121 (there is no `setfield` at that scope, it should be `direct.setfield`). This is the required patch: ```diff --- a/luatex-basics-nod.lua +++ b/luatex-basics-nod.lua @@ -118,7 +118,7 @@ nuts.setcomponents = direct.setcomponents nuts.setdirection = direct.setdirection nuts.setdisc = direct.setdisc nuts.setreplace = direct.setreplace -nuts.setfield = setfield +nuts.setfield = direct.setfield nuts.setkern = direct.setkern nuts.setlink = direct.setlink nuts.setlist = direct.setlist ``` This surfaced because `nuts.setreplace` in the generic code is defined in terms of `nuts.setfield`. Previously `nuts.setreplace` wasn't used anywhere (I think), but since 20th May 2021 it is used when injecting kerns into discretionaries (font-otj.lua): See also https://www.mail-archive.com/ntg-context@ntg.nl/msg98463.html. Minimal not working example is: ``` \font\f=file:{./BaskervilleF-BoldItalic.otf}:mode=node;script=latn;kern=yes; at10pt \f B\-C \bye ``` Fails with: "warning (node filter): error: ./luatex-fonts-merged.lua:5166: attempt to call a nil value (upvalue 'setfield')". Interestingly I can't reproduce the issue with Latin Modern, although it seems to have a similar kern: ``` \font\f=file:lmroman10-regular.otf:mode=node;script=latn;kern=yes; at10pt \f V\-a \bye ``` Originally reported at https://github.com/latex3/luaotfload/issues/194.

hang error
by Hans van der Meer 08 Jul '21

08 Jul '21

Why this: normal plain TeX macro \hang giving an Undefined control sequence error in ConTeXt? This MWE shows it: \starttext \hang \stoptext I would not expect basic plain macro's to crash. If it is intended behaviour I do not think that is the road to go, because this invalidates older documents. But maybe it is just an error in the distribution. dr. Hans van der Meer
