\Umathcodenum and get...dir in lmtx
by Marcel Fabian Krüger 28 May '20

28 May '20

Hi, I had two issues with luametatex: The manual documents getters and setters for the directions: The direction states can be queried and set with: tex.gettextdir() tex.getpardir() tex.setmathdir(<number>) tex.getlinedir() tex.settextdir(<number>) tex.setpardir(<number>) tex.getmathdir() tex.setlinedir(<number>) While there is no problem with the set...dir commands, the get...dir commands don't actually exists. (They can be implemented using tex.get, but it would be nice if either they were added to luametatex or if they were removed from te documentation to avoid confusion.) Additionally the scanning variant of \Umathcodenum seems broken: Take the example document \starttext \directlua{ print('gettextdir:', tex.gettextdir) } \the\Umathcodenum`a \stoptext It works in ConTeXt mkiv, but in lmtx it shown a (non-informative) error: gettextdir: nil tex error > tex error on line 5 in file ./contfail.tex: ! This can't happen (scan char) l.5 \the\Umathcodenum`a 1 \starttext 2 \directlua{ 3 print('gettextdir:', tex.gettextdir) 4 } 5 >> \the\Umathcodenum`a 6 \stoptext 7 I'm broken. Please show this to someone who can fix me. mtx-context | fatal error: return code: 256 (\Umathcodenum`a=123 seems to work though) Also especially these "This can't happen" errors a a it of pain debug without having the option to look into the source which I can't find anywhere. Has that been released? Is it still planned to make it available at some point? Best regards, Marcel Krüger

Dangerous bend metafont/post code?
by Gerben Wierda 28 May '20

28 May '20

To honour Donald Knuth, I’ve use his ‘dangerous bend’ (with attribution of course) in one of my publications. But I only had a low res image. Is the code of this symbol available somewhere so I can do it proper justice in a next edition? G

Hi! With LMTX the following example results in setup > error in line 7, namespace 'naturaltablelocal', key ',' setup > error in line 7, namespace 'naturaltablelocal', key ',' The file runs without error in MkIV. Has something changed or is it a bug? \starttext \bTABLE \bTR \bTD \samplefile{knuth} \eTD \bTD \samplefile{knuth} \eTD \eTR \eTABLE \stoptext This is LuaMetaTeX, Version 2.06.05 current version: 2020.05.25 23:39 Marco

issue with environment and Lua
by Pablo Rodriguez 27 May '20

27 May '20

Dear list, I have added an \xmlflushcontext to a non-minimal environment file and it crashes again and again. I get the following errors: lua error > lua error on line 8 in file cont-yes.mkiv: function call [560]: ...ext/tex/texmf-context/tex/context/base/mkiv/lxml-tex.lua:918: bad argument #2 to 'lpegmatch' (string expected, got table) <empty file> mtx-context | fatal error: return code: 256 Is there any way to be able to know which XML code outputs a table instead of the string ConTeXt expects and complaints about? I already spent three hours and I got nothing. In cases like that, it would be useful that ConTeXt could translate XML + environments to ConTeXt sources. This would make easier to spot errors on documents or issues in ConTeXt. Many thanks for your help, Pablo -- http://www.ousia.tk

Change hyphenation mark
by Marc Trius 27 May '20

27 May '20

Hi, I would like to use a different hyphenation mark (־, U+05be) in Yiddish, as it is the standard in that language. It's my understanding from reading the wiki that this is currently impossible—I am wondering if there is a hack that could accomplish this. Thank you, Marc Trius

Proper presentations with stepping
by Thomas Welter 26 May '20

26 May '20

The presentation examples with stepping always seem to lack page and section numbers because \incrementcounter gets fired on every stepping iteration. For that I adjusted a few lines in spresent-steps.mkiv. You can see an (scientifically-styled) example presentation here: https://github.com/WelterDevelopment/present-steps-context Also I would like to propagate the idea of removing the sectioning heads from the page content and move them to the page header. This does simplify a lot of issues in (non-javascript) stepped presentations: \setuphead[section,subsection][page=yes, placehead=empty] \setupheadertexts[{\getmarking[sectionnumber] \getmarking[section] -- \getmarking[subsectionnumber] \getmarking[subsection]}][] Maybe something like this can be added as a new example presentation in texmf-context\doc\context\presentations\examples because the current present-steps-001 is a little too minimal. If you have any ideas to automate the prevention of auto-incrementing the counters for floats and equations, please don't hesitate to commit changes. Kind regards, Thomas

\setupbackend in MkIV
by Rik Kabel 25 May '20

25 May '20

I cannot get a PDF/A document produced with the latest MkIV beta 2020.05.18 16:46 (LMTX works without issue). Using the example from the wiki (https://wiki.contextgarden.net/PDF/A) I get the error stating: <inserted text> ... \p_file {\backendparameter {xmpfile}}\ifempty \p_file \else \clf_setxmpf... \setup_backend ...end [#1]\the \everysetupbackend l.11 ...ISO coated v2 300\letterpercent\space (ECI)] mtx-context | fatal error: return code: 1 Removing either of the \setupbackend instructions still results in the same error. Same issue for PDF/X. Is it a bug, or is it me? -- Rik
