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

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).

Re: [NTG-context] About vertical typesetting in ConTeXt

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.

check if inside footnote
by Henning Hraban Ramm 04 Aug '20

04 Aug '20

Hi, me again... Is there a check if a macro is called from inside of a footnote, like a system mode *footnote? (Same with captions?) In my current project, index entries should get italic page numbers if they occurr inside of a footnote (or a caption, but that is rare). I’m using different shortcuts for both cases (that call \index with or without processor), but some paragraphs are very confusing (many long footnotes, or footnotes within footnotes), and I could avoid manually analyzing the structure if my macro could determine on its own if it’s called from a footnote. Not-working example: \setupinteraction[state=start] \defineprocessor[kursiv][style=italicface] \define[1]\Idx{\doifmodeelse{*footnote}{\index{#1}}{\index[kursiv->]{kursiv->#1}}#1} \starttext Text --- \index[C]{A}{B}\footnote{Inside\index{FN}}\index{BF} --- \placeregister[index][criterium=all] \stoptext This also shows the text-running-into-footnotes problem with both of my ConTeXt versions: ConTeXt ver: 2020.01.30 14:13 MKIV beta fmt: 2020.4.12 ConTeXt ver: 2020.07.27 16:30 LMTX fmt: 2020.7.28 Hraban

\fontdimen in LuaMetaTeX
by Marcel Fabian Krüger 04 Aug '20

04 Aug '20

Hi, recent LuaMetaTeX versions no longer automatically resize the fontdimen arrays on assignments. Is there a way to manually resize them or is it necessary to reload a patched font you want more fontdimens? Also, there is an issue with the error message (I guess) for font.setfontdimen: \starttext \directlua{font.setfontdimen(0, 8, 0)} \stoptext gives token call, execute: invalid option '%i' to 'lua_pushfstring' stack traceback: [C]: in function 'font.setfontdimen' [ctxlua]:1: in main chunk 1 \starttext 2 >> \directlua{font.setfontdimen(0, 8, 0)} 3 \stoptext 4 Best regards, Marcel

Bug with \wordright in LMTX version 2020-08-03 14:25
by Otared Kavian 04 Aug '20

04 Aug '20

Hi Hans, A file which used to be typeset correctly with the previous versions of lmtx, now produces an error. Despite the error message being extremely cryptic: Error ! Missing number, treated as zero I could guess the origin of the bug, which seems to be \wordright, but although the following minimal example shows a bug it does not produce the same ERROR output page: %%%% the square ''end of proof'' \definesymbol[Fin][\mathematics{\square}] \def\qed{\wordright{\symbol[Fin]}} \starttext \startformula a^2 + b^2 = c^2 \stopformula \qed % the problem is here \stoptext In the above example if one adds something before \qed, then the square end-of-proof appears. However in my real file ConTeXt ouputs an error page and says: Error ! Missing number, treated as zero. Best regards: Otared
