context --luatex does not redirect to LuaTeX
by Jairo A. del Rio 08 Aug '20

08 Aug '20

Hi again! When context --luatex is used with current version: 2020.08.07 23:37 LuaMetaTeX is still used. --engine=luatex has no effect, either. Is that a bug? Thanks Cordially, Jairo :)

Hi Hans, Thanks for the hint which consists in adding an \ifmmode to the definition of \qed. However, as you suggest, one needs some other mechanism in math mode, since with your new definition of \qed the alignment of the formula changes when one adds this close symbol: %%%% begin-example-qed.tex \definesymbol[Fin][\mathematics{\square}] \def\qed{\ifmmode\quad\symbol[Fin]\else\strut\wordright{\symbol[Fin]}\fi} \starttext \startformula a^2 + b^2 = c^2. \stopformula \startformula a^2 + b^2 = c^2. \qed \stopformula One sees that\type{\qed} in the formula changes the alignment of the formula. \qed \stoptext %%%% end-example-qed.tex Thanks a lot for everything: Otared > On 4 Aug 2020, at 13:24, Hans Hagen <j.hagen(a)xs4all.nl> wrote: > > On 8/4/2020 11:17 AM, Otared Kavian wrote: >> Thanks Hans for your explanations. >> The problem I encountered is that, the command \qed is used dozens of time in my text without any issue because it was preceded by something on th eline, but the only place where it was alone after a formula resulted in the error and it was not easy for me to isolate the issue… >> By the way, in mkii it was possible to add \qed on the last line of a math formula, but that does not work anymore: >> \definesymbol[Fin][\mathematics{\square}] >> \def\qed{\strut\wordright{\symbol[Fin]}} >> \starttext >> \startformula >> a^2 + b^2 = c^2. \qed >> \stopformula >> The above formula does not show the close symbol.\qed >> \stoptext >> Is there a way to have something like \qed work in math formulas? > because that's now hwpo wordright works ... > > \def\qed{\ifmmode\quad\symbol[Fin]\else\strut\wordright{\symbol[Fin]}\fi} > > but we probably need something different, something that hooks into display math > > Hans > > > ----------------------------------------------------------------- > Hans Hagen | PRAGMA ADE > Ridderstraat 27 | 8061 GH Hasselt | The Netherlands > tel: 038 477 53 69 | www.pragma-ade.nl | www.pragma-pod.nl > -----------------------------------------------------------------

About the numbering of theorems

Hello, I have a little problem with the numbering of theorems when there is no subsection.

Hi, I uploaded a new lmtx version ... it has a new mechanism for manipulating boxes: http://www.pragma-ade.com/general/magazines/mag-1105-mkiv.pdf (also in distribution) Of course experimental but I bet that some can think of usage.

Registration for 14th ConTeXt Meeting, September 6–12, 2020
by Jano Kula 07 Aug '20

07 Aug '20

Dear all! The 14th ConTeXt Meeting <https://meeting.contextgarden.net/2020/> is in preparation as originally planned. All pre-registered participants are still planning to attend the meeting. The situation is changing every day (mainly travel restrictions), so we have decided to hold the meeting in case the Czech Republic doesn't have red light in most of the countries in September and the number of participants doesn't drop below the critical number. We will not charge a cancellation fee to attendees, if their individual situation changes. In case the meeting is cancelled as a whole in the end, we will ask everybody registered (except students) to donate 20 € minimum to the ConTeXt Group <https://group.contextgarden.net> as sort of collective insurance. The collected money will be used as the cancellation payment to the hosting property. Abstracts <https://meeting.contextgarden.net/2020/abstracts.shtml> have been updated and registration <https://meeting.contextgarden.net/2020/register.shtml> is open until we reach full capacity. See you in Sibřina! Jano

This MWE is an example of strange font behaviour according to the log and I do not understand what is causing it. ConTeXt complains "check count_components with mkiv" when the word 'suffi' is present (see log message below). Now comes the most strange: remove 'suffi' or shorten to 'suff' and the message goes away. I have put the full set of files inside the zip. dr.

Header bottom line vanishing after 87 pages
by Willi Egger 06 Aug '20

06 Aug '20

Hello good morning, I encounter a strange problem when compiling my project. The book has 252 pages, compilation runs without errors. But after 87 pages the bottom frame of the header is turned off. The \setupbackgrounds command is given only once in the preamble. — So I am curious what that can be. I tried to reproduce the problem by a simple 255 page loop, but there the issue does not appear. There is no difference between MKIV and LMTX, no difference in older version and yesteray evening’s version of ConTeXt. My question is whether anybody has an idea how to track down this issue. Kind regards Willi

Placing a section ending depending on odd/even sectionnumber
by Willi Egger 05 Aug '20

05 Aug '20

Hi, now I have another hurdle to be taken :-) — Depending on the odd or even number of the section I have to place an ornament at the end of the section. I have sofar the following setup: \define\stopmysection {\setups{endsection}} \startsetups endsection \doifelse {\currentheadnumber} %{\headnumber[section][current]}{odd} {even} {\vfil {\bf End of even numbered section} \stopsection% } {\vfil {\bf End of odd numbered section} \stopsection% } \stopsetups \starttext \startsection[title=Ward] \setuppagenumbering[conversion=romannumerals] \input ward \stopmysection \startsection[title=Knuth] \setuppagenumbering[conversion=numbers] \input knuth \stopmysection \stoptext However the the evaluation of the sectionnumber results always in “false”, having therefore always odd as a sectionending. What to change in order to get the desired result? Kind regards Willi

Re: [NTG-context] About vertical typesetting in ConTeXt
by Jairo A. del Rio 04 Aug '20

Thank you a lot, Hans. Indeed, the second solution seems to correctly put text into a vertical flow. However, a serious issue with Mongolian script is the horizontal direction: unlike CJK vertical typesetting, the text columns go from left to right, and the following almost works (\definefont gives no ligatures in my computer so I've used \definefontfamily instead) %\definefont does not work as expected \definefontfamily[main][serif][mongolianwhite][features=mongolian] \setupbodyfont[main,24pt] \defineframed [vertical] [ offset=none, align=flushleft, anchoring=left, foregroundstyle={\setupinterlinespace[40pt]}] \starttext %\MyFont \startframed[vertical] ᠣᠢᠷ᠎ᠠ ᠵᠢᠨ ᠡᠳᠦᠷ᠂ ᠦᠪᠦᠷ ᠮᠣᠩᠭᠣᠯ ᠦᠨ ᠰᠢᠯᠢ ᠵᠢᠨ ᠭᠣᠣᠯ ᠠᠢᠮᠠᠭ ᠦᠨ ᠰᠢᠯᠣᠭᠣᠨ ᠬᠦᠬᠡ ᠬᠣᠰᠢᠭᠣᠨ ᠦ ᠰᠢᠭᠦᠬᠦ ᠬᠣᠷᠢᠶ᠎ᠠ ᠨᠢᠭᠡᠨ ᠬᠦᠴᠦᠷᠬᠡᠭᠯᠡᠨ ᠨᠦᠵᠢᠳᠯᠡᠭᠰᠡᠨ ᠶᠠᠯᠠᠲᠣ ᠬᠡᠷᠡᠭ ᠲᠦ ᠰᠢᠭᠦᠯᠲᠡ ᠬᠢᠪᠡ᠃ ᠰᠢᠭᠦᠨ ᠲᠠᠰᠣᠯᠣᠯᠳᠠ ᠪᠠᠷ᠂ ᠵᠠᠭᠠᠯᠳᠣᠭᠳᠠᠭᠴᠢ ᠡᠷᠬᠢᠮᠲᠦ ᠵᠢ ᠬᠦᠴᠦᠷᠭᠡᠭᠯᠡᠨ᠂ ᠨᠦᠵᠢᠳᠯᠡᠭᠰᠡᠨ ᠶᠡᠯ᠎ᠡ ᠪᠡᠷ ᠭᠣᠷᠪᠠᠨ ᠵᠢᠯ ᠦᠨ ᠬᠣᠭᠣᠴᠠᠭ᠎ᠠ ᠲᠠᠢ ᠬᠣᠷᠢᠬᠣ ᠡᠷᠡᠭᠦᠦ ᠪᠡᠷ ᠰᠢᠳᠬᠡᠭᠰᠡᠨ ᠪᠠᠢᠨ᠎ᠠ᠃ \stopframed \stoptext I've attached two files: the ConTeXt output (results so far) and the expected result (done via LuaLaTeX).

Hi, list. I've found a (sort of) way to do LTL typesetting in Lua(La)TeX based on "chickenize", a LuaTeX package. The font used is available here; http://www.mongolfont.com/en/font/mnglwhiteotf.html %Just for testing in LaTeX \documentclass{article} \usepackage{luacode} \usepackage{fontspec} \setmainfont{Mongolian White}[Renderer=Harfbuzz,Script=Mongolian] \begin{luacode*} -- How do I do this in ConTeXt? userdata = userdata or {} userdata.mongolian = function(head) --Ugly hackish line rotation rot = node.new(node.id("whatsit"),node.subtype("pdf_literal")) rot2 = node.new(node.id("whatsit"),node.subtype("pdf_literal")) for line in node.traverse_id(0,head) do w = line.width/65536*0.99625 rot.data = "-1 0 0 -1 "..w.." 0 cm" rot2.data = "-1 0 0 -1 "..-w.." 0 cm" line.head = node.insert_before(line.head,line.head,node.copy(rot)) node.insert_after(line.head,node.tail(line.head),node.copy(rot2)) end return head end \end{luacode*} \def\startmongolian{\directlua{luatexbase.add_to_callback("post_linebreak_filter", userdata.mongolian, "mongolian")}} \def\stopmongolian{% \par\directlua{luatexbase.remove_from_callback("post_linebreak_filter", "mongolian")}% } \usepackage{graphicx} \begin{document} \rotatebox{90}{% \parbox{8cm}{% \startmongolian \begin{flushleft} ᠣᠢᠷ᠎ᠠ ᠵᠢᠨ ᠡᠳᠦᠷ᠂ ᠦᠪᠦᠷ ᠮᠣᠩᠭᠣᠯ ᠦᠨ ᠰᠢᠯᠢ ᠵᠢᠨ ᠭᠣᠣᠯ ᠠᠢᠮᠠᠭ ᠦᠨ ᠰᠢᠯᠣᠭᠣᠨ ᠬᠦᠬᠡ ᠬᠣᠰᠢᠭᠣᠨ ᠦ ᠰᠢᠭᠦᠬᠦ ᠬᠣᠷᠢᠶ᠎ᠠ ᠨᠢᠭᠡᠨ ᠬᠦᠴᠦᠷᠬᠡᠭᠯᠡᠨ ᠨᠦᠵᠢᠳᠯᠡᠭᠰᠡᠨ ᠶᠠᠯᠠᠲᠣ ᠬᠡᠷᠡᠭ ᠲᠦ ᠰᠢᠭᠦᠯᠲᠡ ᠬᠢᠪᠡ᠃ ᠰᠢᠭᠦᠨ ᠲᠠᠰᠣᠯᠣᠯᠳᠠ ᠪᠠᠷ᠂ ᠵᠠᠭᠠᠯᠳᠣᠭᠳᠠᠭᠴᠢ ᠡᠷᠬᠢᠮᠲᠦ ᠵᠢ ᠬᠦᠴᠦᠷᠭᠡᠭᠯᠡᠨ᠂ ᠨᠦᠵᠢᠳᠯᠡᠭᠰᠡᠨ ᠶᠡᠯ᠎ᠡ ᠪᠡᠷ ᠭᠣᠷᠪᠠᠨ ᠵᠢᠯ ᠦᠨ ᠬᠣᠭᠣᠴᠠᠭ᠎ᠠ ᠲᠠᠢ ᠬᠣᠷᠢᠬᠣ ᠡᠷᠡᠭᠦᠦ ᠪᠡᠷ ᠰᠢᠳᠬᠡᠭᠰᠡᠨ ᠪᠠᠢᠨ᠎ᠠ᠃ \end{flushleft} \stopmongolian } } \end{document} I can rotate boxes in ConTeXt using other methods than those used in LaTeX. However, my main concern is about "translating" the Lua(La)TeX piece to be used in ConTeXt. I've read about "finalizers" in the CLD manual and somewhere online, but I don't know how to access to node.subtype("pdf_literal"). I'll be happy to know about a better solution if ConTeXt offers it so it is accessible to other users. Thank you in advance.
