Hi Hans, here is my minimal sample: \starttext \input zapf \stoptext And here the error I get: lua error > lua error on line 1 in file a.tex: ...ce0dde776fb1556f32e/formats/luajittex/lpdf-ini-macro.lua:1029: attempt to call upvalue 'pdfsetpageresources' (a nil value) 1 >> \starttext 2 \input zapf 3 \stoptext Just in case it helps, Pablo -- http://www.ousia.tk

two (2) questions about footnotes
by Thomas A. Schmitz 27 May '19

27 May '19

Hi all, I have two questions/problems about footnotes. Here is a minimal example, which does not compile in this form: \unexpanded\def\MyRule{\blackrule[width=\textwidth,height=3pt]} \setupfootnotes[rule=\MyRule] \starttext Test1: \index{Adam}Adam.\footnote{Test2: \index{Eve}Eve.} \page \placeregister [index] \stoptext (1) In my current project, the publisher wants the rule separating text and notes to extend across the entire text width. I found the \blackrule command and its use in the setup on the mailing list, many years ago, proposed by Steffen Wolfrum, but it doesn't work (anymore?); I get "tex error on line 3 in file /tmp/test.tex: ! Missing \endcsname inserted." Any hints? (2) Again, something that has been asked on the mailing list, but not received any replies: would it be possible to have the index report that "Eve" occurs inside a footnote? So it says "Eve 1 n. 1" or something like that? Thanks a lot, and all best Thomas

Fontloader
by Herbert Voss 26 May '19

26 May '19

I had a problem with the fontloader and luatex. I tried to run my test document with context (latest minimal) to compare the output, but I failed. The font LibertinusKeyboard-Regular.otf https://ctan.org/tex-archive/fonts/libertinus-fonts/ uses ligatures especially for the keys above 0xFFFF However, I cannot get it run with latest mkiv. It is no problem with xetex. It should print only the five keys and not the ones for every single letter. Herbert \font\keyboard=LibertinusKeyboard-Regular.otf \starttext \keyboard Tab Entf Enter Capslock Windows \stoptext

Typesetting Markdown
by Thangalin 26 May '19

26 May '19

Hi folks! I'm thinking about writing a series of blog posts about how to typeset Markdown using ConTeXt. I've written the first part and am wondering if anyone would be interested in reading more: https://dave.autonoma.ca/blog/2019/05/22/typesetting-markdown-part-1/ Thank you!

serial letters
by Henning Hraban Ramm 24 May '19

24 May '19

How would you approach serial letters, e.g. to all members of a club? (Actually I need to send out donation receipts.) I’d like to use the letter module, since my usual letter design is using it. I can export the addresses to CSV, JSON, Lua tables or whatever or transfer them to a SQLite db. Would it make more sense to read them in Lua and combine this data with a buffer, or to write a single tex file for every letter? I know how to do the latter, but I’d like to learn a more ConTeXt-ish way. Would it make sense to use the bibliographies module?

no bookmark prerollling in bookmark option
by Pablo Rodriguez 23 May '19

23 May '19

Dear list, I have the following sample: \def\MyContent{This is expanded content} \enabledirectives[references.bookmarks.preroll] \setupinteraction[state=start, title={\MyContent}] \placebookmarks[section] \starttext \section{\MyContent} \startsection[title=\MyContent] \stopsection \startsection[title=\MyContent, bookmark=\MyContent] \stopsection \stoptext Bookmarks aren’t prerolled when the bookmark option from \startSECTION is used. I think it may be a bug. Could anyone confirm it? Many thanks for your help, Pablo -- http://www.ousia.tk

Hello All, I wrote the wiki page "https://wiki.contextgarden.net/Fraktur_fonts" on my experiences of ConTeXt and three Fraktur fonts. 4 result images are still missing. I didn't succeed in uploading them to the server in reasonable time. Could somebody, who has already uploaded images, please, do it for me? The 4 images are appended here. Best wishes, Rudolf

Strange behavior concerning pdf-output of .png-externalfigures

Even with my scanner software I produce always .jpg-images though it is capable to produce .pdf-output too. The only .pdf-files I'm doing are made by ConTeXt-LMTX! I shall append another, interesting MWE. There is a .png-image which is, as it occasionally happens, represented as it should, by ConTeXt. And then the same .png-image to which I added a red frame by GIMP2.10. This one shows artefacts in ConTeXt! I'm adding the .log-file too. There again is a luatex-warning, as I could observe them often in ConTeXt-LMTX: ------------------------------------------------------------- luatex warning > pdfe: invalid 11 0 R object at offset 41603 ------------------------------------------------------------- Please, what does mean it? I fear there is something wrong with the .png-handling of ConTeXt/luatex. The outputs of feh image----red-frame.png gm display image----red-frame.png are looking ok. And GIMP2.10 has produced all image-files.

XML export: basic questions
by Procházka Lukáš Ing. 22 May '19

22 May '19

Hello, suppose having "Main.mkiv": ---- \setupbackend[export=yes] \starttext \startsection[title={Sec},MyPar=MyVal] \input knuth \stopsection \stoptext ---- Some questions concerning XML export: 1. Normally, with \setupbackend[export=yes], Ctx creates "Main-export" directory containing (among others) Main-raw.xml, and Main-tag.xhtml and some subdirs. Is there a way to tell Ctx to produce just one XML file with a prescribed name which wouldn't be placed in any subdir? In my case - to produce "Main.xml" (instead of "Main-export/Main-raw.xml"), other files to be omitted? 2. Is there a way to export user parameters used in \section? In my case: \startsection[title={Sec},MyPar=MyVal] uses user parameter "MyPar" with value "MyVal", but "MyPar" is not transmitted into XML; the goal is to have <section detail="section" chain="section" implicit="1" level="3" MyPar="MyVal" > which would allow some filtering when reprocessing that XML. - Or is there another way, like enclosing into a user tag: \starttag[MyTag] \startsection[title={Sec},MyPar=MyVal] \input knuth \stopsection \stoptag which would export into: <MyTag> <section detail="section" chain="section" implicit="1" level="3" MyPar="MyVal"> ... </section> </MyTag> Best regards, Lukas -- Ing.

section to have different conversion in body part and appendices
by Procházka Lukáš Ing. 22 May '19

22 May '19

Hello, is there a way to tell \section (or other heads) to be "number-converted" differently in bodypart and appendices? Something like: ---- \setuphead[section][] % e.g. "appendices:numberconversion=A"? \starttext \starbodyamtter \section{In body} % To produce "1. In body" \stopbodymatter \startappendices \section{In apps} % To produce "A In apps" \stopappendices \stoptext ---- Best regards, Lukas -- Ing.
