Typesetting unicode characters
by Thangalin 31 Mar '22

31 Mar '22

Hi list, An XML document includes the 👍 emoji, as shown in the following snippet: <html> <head><meta charset="utf8"/></head> <body> <div class="bubblerx"> <p>Thumbs up emoji: &#55357;&#56397;</p> </div> </body </html> The document is typeset using ConTeXt, but the thumbs up emoji isn't in the PDF. Neither Noto Emoji nor Open Sans Emoji fonts will render. Does anyone have a minimal example that shows how to typeset such escaped entities? When the emoji is added directly to a document, it works fine: \definefont [TextFontEmoji] [opensansemoji] \starttext \TextFontEmoji{Thumbs up emoji: 👍} \stoptext Is there something special that needs to be set for ConTeXt to interpret the escaped unicode values as an emoji? Thank you!

How to group list of figures and list of tables by chapter?
by Werner Schmidt 31 Mar '22

31 Mar '22

Hi, How can I set up \placelistoffigures and \placelistoftables that figures and tables are grouped by chapter, i.e. separated by a blank line between chapters (see example below)? Thanks in advance for your help! Best Werner (Default:) Figures 1.1 Caption Chapter01-Section01-01 . . . . . . . . . . . . . . . . . 2 2.1 Caption Chapter02-Section01-01 . . . . . . . . . . . . . . . . . 3 2.2 Caption Chapter02-Section01-02 . . . . . . . . . . . . . . . . . 3 3.1 Caption Chapter03-Section01-01 . . . . . . . . . . . . . . . . . 4 3.2 Caption Chapter03-Section01-02 . . . . . . . . . . . . . . . . . 4 3.3 Caption Chapter03-Section02-03 . . . . . . . . . . . . . . . . . 4 (Wanted:) Figures 1.1 Caption Chapter01-Section01-01 . . . . . . . . . . . . . . . . . 2 2.1 Caption Chapter02-Section01-01 . . . . . . . . . . . . . . . . . 3 2.2 Caption Chapter02-Section01-02 . . . . . . . . . . . . . . . . . 3 3.1 Caption Chapter03-Section01-01 . . . . . . . . . . . . . . . . . 4 3.2 Caption Chapter03-Section01-02 . . . . . . . . . . . . . . . . . 4 3.3 Caption Chapter03-Section02-03 . . . . . . . . . . . . . . . . . 4

command line arguments to specify output directory
by A A 30 Mar '22

30 Mar '22

Dear All, I would like to ask whether there exists a command line option to the context executable which would allow me to specify the directory in which I would like my output to be dumped. I have noticed that if I call the executable outside the directory in which the .tex file resides, my supporting files (and resulting pdf) are dumped outside the directory in which the .tex file is located. Any help would be most welcome. Thanks for your consideration. Regards, Amine

Xml - Lua - context
by Thomas A. Schmitz 30 Mar '22

30 Mar '22

And here comes question 2, a very basic one: on A4 landscape pages, I want to place two images next to each other (like the spread pages of a book). What would be the preferred way of the really competent users to do this, again keeping in mind that I want to loop over page numbers in a pdf file and thus am coding in Lua. So far, I have tried or thought about: 1. Embedded xtable This is what I’m using now, an xtable of two columns for every A4 page. It works, but I wonder if it’s a good method. 2. combinations This appeared to be the most natural approach (because it’s what combinations are for), but I ran into expansion problems, added a few “function () end” in my code, but couldn’t make it compile. Combinations, combined with framed and externalfigure, are difficult to write in Lua - or am I too stupid to find the winning combination (sorry for the puns). 3. columns Again, this would seen like a natural approach, having every A4 page set up as two columns, but maybe that’s overkill? I’d be curious to know what you think! All best Thomas

Trying to get a simple bibliography
by A A 29 Mar '22

29 Mar '22

Hi All, I'm trying to get a simple bibliography to work with ConTeXt. Here's what I have so far: *test.tex* \usebtxdataset[bibliography.bib] \starttext \startbodymatter See \cite[proofwiki] \stopbodymatter \startbackmatter \startsection[title=Bibliography] \stopsection \stopbackmatter \stoptext *bibliography.bib* @misc{ proofwiki, title={{Definition:Collation - ProofWiki}}, author={{ProofWiki}}, howpublished={ \href{https://proofwiki.org/wiki/Definition:Collation}{link} }, journal={{ProofWiki}}, year={2021} } When I compile test.tex it generates a pdf, but the citation is not included in the body matter. Also the actual reference is not present in Bibliography. What am I doing wrong? Regards, Amine

Fwd: documentation for \cite and \setupcite commands
by A A 28 Mar '22

28 Mar '22

Another question, *Bibliographies, the ConTeXt way *by Hans Hagen and Alan Braslau introduces a parameter not shown in the \cite doc in ConTeXt garden, namely "righttext". Moreover, this answer <https://tex.stackexchange.com/questions/73131/how-to-add-page-numbers-to-ap…> introduces an "extras" parameter, also not included in ConTeXt garden. Am I missing something here? ---------- Forwarded message --------- From: A A <amine.aboufirass(a)gmail.com> Date: Sun, 27 Mar 2022 at 20:16 Subject: Fwd: documentation for \cite and \setupcite commands To: <ntg-context-request(a)ntg.nl> Nevermind, for \cite there is detailed documentation here <https://wiki.contextgarden.net/Command/cite> Can I safely assume that \setupcite uses the same arguments? Can I generalize this assumption to all \command and \setupcommand in ConTeXt? ---------- Forwarded message --------- From: A A <amine.aboufirass(a)gmail.com> Date: Sun, 27 Mar 2022 at 20:09 Subject: documentation for \cite and \setupcite commands To: <ntg-context-request(a)ntg.nl> Dear All, Does anyone know where I can find more or less detailed information about the \cite and \setupcite commands? I checked ConTeXt garden and the book "ConTeXt: An excursion". I also checked the mailing list search engine and did a couple of generic google searches but found nothing to the level of detail I'm looking for. Thanks in advance for your help. Regards, Amine

Xml - lua - context
by Thomas A. Schmitz 28 Mar '22

28 Mar '22

Dear all, For a small project, I have two questions (without MWE…) on processing xml via Lua and context. I’ll write two messages so eager volunteers can reply more easily! So question one: given an xml structure like this <section> <sectiontitle> Introduction: the <em>Iliad</em> </sectiontitle> <sectionlist> Introduction: the <em>Iliad</em> </sectionlist> </section> I want to typeset the section title with some added information. Since I’m processing in a loop, I thought this would be easier in Lua, so I have something like this: local i = 0 local sessions = { “April 2”, “April 9”, “April 16” } -- etc. function xml.functions.section(t) i = i + 1 local raw_section = xml.text (t, "/sectiontitle") local section_head = i .. ". session, " .. sessions [i] .. ": " .. raw_section context.startsection { title=section_head } lxml.flush (t) context.stopsection () end However, this means that the section_head is serialized as a string and not processed according to the xml setups, so I have “the <em>Iliad</em>” in my typeset document. How can this be avoided? How can I have the <em>...</em> processed instead of serialized in the section title? Thanks for looking at my code! Thomas

Line numbering inside display math with mathalign and splitformula
by śrīrāma 28 Mar '22

28 Mar '22

Hi everyone, I have a document with lots of maths. I am using \start...\stoplinenumbering to place line numbers in the inner margins with \setuplinenumbering [location=inner, style=\ttx] The weird thing is I have many display math blocks that break across page(s) using \start...\stopsplitformula with \start...\stopmathalignment. Curiously, the line numbering does not appear in these splitformula blocks alone. (It works for \start...\stopformula) blocks[*]. Below is a MWE: %%% start example \starttext \startlinenumbering \input knuth \startformula\startmathalignment \NC {\mathcal H}_0 \NC : \text { the null hypothesis } \NR \NC {\mathcal H}_1 \NC : \text { the alternate hypothesis } \NR \stopmathalignment \stopformula \startsplitformula\startmathalignment \NC t \NC = f_t(x) \NR \NC m_t \NC = f_m(x) \NR \stopmathalignment\stopsplitformula \stoplinenumbering \stoptext %%% stop example Further, [*]when \start...\stopmathalignment is used, only one (vertically centered) line number appears for the entire block. Is there a way to have the 'usual' line numbering inside the math blocks also? It is not a big problem as such: I can do without it since important equations are numbered anyway in the document (and I can use that to refer to them) but I was just curious if it is possible and/or I have missed something. Many thanks, Sreeram
