Number conversion in btxlist and citations
by kauśika cittūr 16 Sep '21

16 Sep '21

Dear all, I have a simple btx definition 'mylist' for which I have written a simple publ-imp-mylist.lua and publ-imp-mylist-mkvi. In that latter I have ⋮ \definebtx [mylist] [default=default,specification=mylist] \definebtxrendering [mylist] [specification=mylist] \setupbtxlist [mylist] [numberconversion=myconv] ⋮ I have define the required setups for every category entry as well. I have verified that this btxrendering works. I have also verified that my conversion set 'myconv' is functional (I am using it for page numbers and section headings). However, the numbers used in the citation are not converted. That is, 'numberconversion=myconv' seems to have no effect. What am I doing wrong? Please advise. Thanks, kauśika

Implementing a custom authorconversion for bibliographies
by Joey McCollum 15 Sep '21

15 Sep '21

Hi, I mentioned this in an earlier e-mail but thought that now might be a good time to describe this issue in detail. I'd like to define a new authorconversion that renders the first author in a list differently than the remaining authors in the list. Specifically, I'd like to use the "inverted" authorconversion for the first author and the "normal" authorconversion for the rest. In the newer bibl-bib.lua file, I can see what I might have to modify to accomplish this (I added the if combiner == "invertedfirst" block): ``` function authors.concat(author,combiner,what,settings) if type(combiner) == "string" then combiner = authors[combiner or "normal"] or authors.normal end local split = splitauthors(author) local setting = settings[what] local etallimit, etaldisplay, etaltext = 1000, 1000, "" if setting then etallimit = settings.etallimit or 1000 etaldisplay = settings.etaldisplay or etallimit etalltext = settings.etaltext or "" end local max = #split if max > etallimit and etaldisplay < max then max = etaldisplay end if combiner == "invertedfirst" then for i=1,max do if i == 1 then split[i] = authors.inverted(split[i],settings) else split[i] = authors.normal(split[i],settings) end end else for i=1,max do split[i] = combiner(split[i],settings) end end local result = bibtexconcat(split,settings) if max < #split then return result else return result .. etaltext end end ``` Unfortunately, this doesn't seem to do anything. It's not clear to me how bibl-bib.lua and bibl-bib.mkiv are being used by the other publication support modules, if they're being used at all (publ-ini.mkiv doesn't appear to register it, anyway). Is there another file I'd have to change to make "invertedfirst" a working authorconversion? Is there a similar block of code in publ-ini.lua where I should be implementing this change instead? Thanks! Joey

Changing the style of author’s surname in a custom bibliographical style
by Tomáš V 15 Sep '21

15 Sep '21

Greetings, I am trying to make a bibliographical style that would comply to the ISO 690 standard and I have a few questions: 1) The name of the author need to be written in the inverted format (e.g. Knuth, Donald). It is also customary to write the surname either in uppercase or in small caps (e.g. KNUTH, Donald). If I wanted to change the whole name to small caps I’d do something like this: \btxdoif {author} { {\sc \btxflush{author}} \btxperiod } How do I change the “font” of the surname only? Can this be done by redefining a TeX macro (like in BibLaTeX’s \mkbibnamefamily) or is this done by changing some Lua code? 2) As I have said, the name has to be inverted. This is done by setting authorconversion to inverted. I’ve tried doing this like this: \setupbtx[iso690:list][authorconversion=inverted,] and this: \setupbtxlist[iso690][authorconversion=inverted,] Neither of these options work, but this works: \setupbtx[default:list][authorconversion=inverted,] I’m confused—why does changing the default option work and changing the option for my style doesn’t? Here's a MWE for both of my problems: % publ-imp-iso690.mkiv \startbtxrenderingdefinitions[iso690] \definebtx [iso690] [ default=default, specification=iso690, ] \definebtxrendering [iso690] [ specification=iso690, numbering=yes, ] \setupbtx[default:list] [ authorconversion=inverted, ] % field definitions \starttexdefinition btx:iso690:author \btxdoif {author} { \btxflush{author} \btxperiod } \stoptexdefinition % book definition \startsetups btx:iso690:list:book \texdefinition{btx:iso690:author} \removeunwantedspaces \stopsetups % publ-imp-iso690.lua local specification = { name = "iso690", categories = { }, } local categories = specification.categories categories.book = { required = { "title" }, optional = {"author"}, } return specification Thanks for your help, Tomáš

PDF metadata and pdfx keys
by kauśika cittūr 15 Sep '21

15 Sep '21

Dear all, In my documents I use \setupinteraction [ author={AuthorName}, title={MyTitle}, subtitle={MySubtitle}, ] to set the document metadata. I also use \startluacode local metadata = lpdf.getmetadata(); metadata['producer']='author'; metadata['creator']='author'; \stopluacode to set the creator and producer. However, the document produced by ConTeXt still has the user defined keys (pdfx:) written in the metadata. I have gone through lpdf-xmp.lua, lpdf-ini.lua and back-ini.lua. Yet, I am not able to figure out how to prevent the pdfx: tags from being written. Is it possible to prevent them from being written? I prefer not to tamper with any of the ConTeXt distribution files. In this case, is there something I can do per-document to prevent these tags from being written? Please advise. Thanks, kauśika

Hi, From https://blog.tecosaur.com/tmio/2021-08-38-roaming.html " We’ve long been able to export to LaTeX files with ox-latex, but now you can export to ConTeXt too with ox-context! While only just released, a lot of work has already gone into this — with development starting almost a year ago by the commit history." Link : https://github.com/Jason-S-Ross/ox-context Great!

Roman PDF labels
by Sylvain Hubert 14 Sep '21

14 Sep '21

Dear List, Do we have something like "\pagenumbering{roman}" in latex, which sets the pdf labels (page numbers for pdf viewers, not the ones rendered in the footer) to roman numbers? Here's a MWE for latex: \documentclass{report} \usepackage{hyperref} \begin{document} \pagenumbering{roman} \tableofcontents \listoffigures \listoftables \pagenumbering{arabic} \chapter{Abc} \end{document} Thanks! Best, Sylvain

Headline with numbers in margin doubleside layout
by juh 14 Sep '21

14 Sep '21

Hi all, I have a doubleside layout with a big outer margin. When I set alternative=margin in setuphead the chapter numbers appear in the left margin which is the outer margin on left pages, but the inner margin on right pages. While this looks good on left pages, there is much free space on right pages. I would like to use this space for headlines to balance the impression. Is it possible to assign headlines to the textarea+margin somehow only on right pages so that headlines would run into the outermargin o right pages??

update
by Hans Hagen 13 Sep '21

13 Sep '21

Hi, I uploaded a new lmtx (had forgotten to to it friday) . There are not that many visible changes but on is that i'm playing with some 'improvements' to inserts. Hopefully there are no side effects but the idea is to have somewhat better (more robust and predictable) support for e.g. footnotes in situations that are not natural to tex (like columns). The first mechanism to benefit from that is page columns but all that is a stepwise process. I keep track of that in yet another lowlevel manual. These column things are on the agenda for next month and beyond. (In a next upload the new marking and tabulate optimization might become default but for now i test that locally.)

Setting up the double pages of part beginnings
by Christian Dekant 13 Sep '21

13 Sep '21

Dear List, I am trying to set up double pages at the beginning of a new part in such a way that: - on an odd/right-hand page there will be number and the title typeset in some fashion, and - on the even/left-hand page there should be a full (printpaper)size image. If the part title ends up on an even page then there is no additional page break (but then image and title are not on the same double-page obviously). But there is a page break (and an empty left page) when the part title ends up on an odd page (when you put page=right e.g.) as in the following example: % % How to get rid of the empty page preceding a part title? % \setuppagenumbering [alternative=doublesided] \setupexternalfigures[location=default] % cow % startTEXpage does not increase page number => incrementpagenumber % trimming in the print shop => printpaperwidth/height \define[1]\FullScreen{\startTEXpage\externalfigure[#1][width=\printpaperwidth,height=\printpaperheight]\stopTEXpage\incrementpagenumber} % tried page=yes/no/right/odd \setuphead [part] [placehead=yes, page=right, before={\nowhitespace}, % ??? ] \starttext \completecontent \FullScreen{cow} \startpart[title={A nice part}] Some text ... \stoppart \FullScreen{cow} \startpart[title={A nice part}] Some text ... \stoppart \stoptext On an additional note: I would love to utilise the XML capabilities of context, so ... is the usage of \startTEpage XML-export-friendly? Anyway, best regards, thank you for your patience in advance and a happy weekend for everybody! Cheers Christian
