Acrobat doesn’t display some imported metadata
by Pablo Rodriguez 19 Sep '21

19 Sep '21

Dear list, I have the following sample to import metadata (title, author, subject, keywords and dates). \starttext \startluacode function document.transfer_metadata(name) local main_doc = lpdf.epdf.load(name) lpdf.addtocatalog("Lang", lpdf.unicode(main_doc.Catalog.Lang), main_doc.Catalog.Lang) lpdf.addtoinfo("Title", lpdf.unicode(main_doc.Info.Title), lpdf.string(main_doc.Info.Title)) lpdf.addtoinfo("Subject", lpdf.unicode(main_doc.Info.Subject), lpdf.string(main_doc.Info.Subject)) lpdf.addtoinfo("Keywords", lpdf.unicode(main_doc.Info.Keywords), lpdf.string(main_doc.Info.Keywords)) lpdf.addtoinfo("Author", lpdf.unicode(main_doc.Info.Author), lpdf.string(main_doc.Info.Author)) lpdf.addtoinfo("CreationDate", lpdf.string(main_doc.Info.CreationDate)) lpdf.addtoinfo("ModDate", lpdf.string(main_doc.Info.ModDate), main_doc.Info.ModDate) lpdf.epdf.unload(name) end \stopluacode \unexpanded\def\TransferMetadata#1% {\ctxlua{document.transfer_metadata("#1")}} \startTEXpage[offset=1em, align=center] \ssbf metadatos\\importados \TransferMetadata{metadata.pdf} \stopTEXpage \stoptext Importing from https://pdf.ousia.tk/metadata.pdf gives https://pdf.ousia.tk/imported-metadata.pdf. Imported metadata from title, creation and modification dates are not displayed right in Acrobat. Other PDF viewers display these metadata fine. How can I get that Acrobat displays the metadata from the imported document? Many thanks for your help, Pablo -- http://www.ousia.tk

improve bad habits deduplicate redundant defined values
by juh 18 Sep '21

18 Sep '21

Dear all, these are quite general questions but here they come. I defined modular styles for an organisation so that we can use different layouts with the same look and feel but still have many options to change things in a special document. I have styles for colors, fonts which are used everywhere but also styles for heads that are only used in legal context and other heads-styles used in other contexts. This works brilliant. I can even overwrite styles for one document only. I'd like to name this a cascading approach. While doing this I learned a lot and changed the way the style files are organised from time to time. Currently I start with colors and fonts. Then comes the page dimension definitions, makeups, headers and footers, headlines, the toc styles, lists and tables. Does anyone has a similar approach with a strong opinion how to organise the cascade? While working on this I often found that I defined something twice, because I forgot to delete a setup-command in a newly structured file. Is there a way to test this? Can I grep for a warning in the log files to find these duplicates?

Exclude bibliographic entries from list even when cited with \cite
by Joey McCollum 16 Sep '21

16 Sep '21

Hi, It's taken a couple weeks, but I nearly have a working bibliographic rendering for SBL style ready. I'm hosting the .lua and .mkvi files I have so far, as well as a test .bib and .tex file, on GitHub at https://github.com/jjmccollum/context-sbl. The look of the rendering seems to be correct for all of the examples, so the last remaining tasks mostly concern some lower-level technical issues. Because of the way that SBL style renders entries that are contained in other works (e.g., a chapter in a book that is part of a multivolume collection), it seemed natural to accommodate this by allowing entries to have cross-references to other entries. The rendering process can then be handled through recursive subcitations with different alternatives. In general, I handle these subcitations with the \textcite command, so that "higher-level" entries are not added to the list when they are only subcited. An important guideline that I still have to implement works in the opposite direction: it says that entries in certain categories should not be added to the list, but the books or collections containing them should be. I think I could make this work for the subcitation using the \listcite or \cite command recursively. But is there a way to conditionally handle whether or not to add the entry to the list after I invoke the \cite command, or is this built into the \cite command at a low level? If I had to, I could define an \autocite command that does all of these checks first, but if it's possible to keep the common \cite command instead of forcing users to use a different command, that would be preferable. Thanks! Joey

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

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
