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

mathcal generates error in ConTeXt
by A A 26 Mar '22

26 Mar '22

Dear All, I am using pandoc to covert a file called test.tex from LaTeX to ConTeXt. Here are the contents of test.tex: *\documentclass{article}* *\begin{document}* *\mathcal{A}* *\end{document}* The file compiles OK with the following command and I see a resulting pdf: *latexmk -pdflatex test.tex* Then I try to convert with pandoc: *pandoc -f latex -t context -o test_context.tex test.tex* Pandoc appears to successfully generate a file test_context.tex containing the following: *\mathcal{A}* Then I try to compile the test_context.tex file: *context test_context.tex* Which unfortunately results in an error: *resolvers | formats | executing runner 'run luametatex format': C:/context/tex/texmf-win64/bin/luametatex --jobname="./test_context.tex" --fmt=C:/context/tex/texmf-cache/luametatex-cache/context/5fe67e0bfe781ce0dde776fb1556f32e/formats/luametatex/cont-en.fmt --lua=C:/context/tex/texmf-cache/luametatex-cache/context/5fe67e0bfe781ce0dde776fb1556f32e/formats/luametatex/cont-en.lui --c:currentrun=1 --c:fulljobname="./test_context.tex" --c:input="./test_context.tex" --c:kindofrun=1 --c:maxnofruns=9 --c:texmfbinpath="C:/context/tex/texmf-win64/bin"* *system > callbacks > not registering frozen 'local_box_filter'* *system >* *system > ConTeXt ver: 2021.11.02 10:03 LMTX fmt: 2021.11.4 int: english/english* *system >* *system > 'cont-new.mkxl' loaded* *open source > level 1, order 1, name 'C:/context/tex/texmf-context/tex/context/base/mkxl/cont-new.mkxl'* *system > beware: some patches loaded from cont-new.mkiv* *close source > level 1, order 1, name 'C:/context/tex/texmf-context/tex/context/base/mkxl/cont-new.mkxl'* *system > files > jobname './test_context', input './test_context.tex', result './test_context'* *fonts > latin modern fonts are not preloaded* *languages > language 'en' is active* *open source > level 1, order 2, name './test_context.tex'* *tex error > tex error on line 1 in file ./test_context.tex: \textfont0 is undefined in (text) char, font id 0, character 63)* *<line 3.1>* * $\mathcal{A}$* *1 >> $\mathcal{A}$* *2* *Somewhere in the math formula just ended, you used the stated character from an* *undefined font family.

zint module on LMTX
by Pablo Rodriguez 25 Mar '22

25 Mar '22

Dear list, using latest LMTX and following the steps from https://wiki.contextgarden.net/Barcodes#Zint_module, I’m afraid I don’t get any barcode either in Linux or Windows. Minimal sample: \starttext \usemodule[zint] \barcode[alternative=isbnx, text=9783865419026, width=4cm] \stoptext Error message is rather weird on Linux: optional > using library '/home/ousia/context/tex/texmf-linux- 64/bin/lib/luametatex/zint/libzint.so' zint > unknown barcode alternative 'isbnx' zint > zint > valid barcode alternatives: zint > [...] zint > isbn zint > isbnx [...] It seems that a valid barcode alternative ends up being unknown to the library. What am I missing here? Many thanks for your help, Pablo

redefining xmlsetups inside a XML document
by mf 24 Mar '22

24 Mar '22

Hello, I'm trying to add new templates (xmlsetups) from the XML document itself. See the attached MWE. - the XML document is a simple XHTML file - in the "head" element there's a "script" element with the "type" attribute set to "text/vnd.context", whose contents are then passed to \xmlcontext - the "body" element has a "data-xmlsetups" attribute whose value should tell which xmlsetups is to be applied on the body contents (it's defined in the "script" element above) If it worked, the resulting PDF should show the body element, followed by a "Hello world!" paragraph written in red. But it does not work, because there's something I'm missing in the redefinition and application of xmlsetups. To try the MWE, type: context --environment=nested-xmlsetup.tex --forcexml nested-xmlsetup.xhtml Massi

Chapter number retrieval
by Willi Egger 23 Mar '22

23 Mar '22

Hello everybody! I would like to typeset the chapter title without number in the text. — However I still would need to retrieve the number for a calculation in a MetaFun graphic. I assume, that even though this number is not typeset, it is kept in the background. How to retrieve it? Kind regards Willi
