getting number from context.figurewidth
by Pablo Rodriguez 28 Oct '21

28 Oct '21

Dear list, I have the following sample: \starttext \startluacode document.sample = "xml-mkiv.pdf" context.getfiguredimensions({ document.sample }) context(context.figureheight) context.par() context(tex.dimen.paperheight) \stopluacode \stoptext Is there a way that I can get a number from context.figureheight, such as I get it from tex.dimen.paperheight? Many thanks for your help, Pablo -- http://www.ousia.tk

XML-processing: Error with hyphenatedurl
by denis.maier＠unibe.ch 27 Oct '21

Hi, I've receiving errors that seem to be related to hyphenatedurl. The problem is I cannot really reproduce it in a MWE. The example below works, but if I include the link in my real document, I'am getting this error message (copied from -error.log): %%%%%%%%%%%%%%%%%%%%% return { ["errortype"]=1, ["filename"]="", ["lastcontext"]="\n<to be read again> \n \n \\xdef<file://xdef> \n<macro> \\expanded<file://expanded> \n #1->\\xdef<file://xdef> \n \\m_syst_helpers_expanded<file://m_syst_helpers_expanded> {\\noexpand #1}\\m_syst_helpers_expanded \n<macro> \\22>:xml:ext-link<file://22%3e:xml:ext-link> \n #1->\\begingroup<file://begingroup> \\expandUx<file://expandUx> \\expanded<file://expanded> \n {\\goto {\\hyphenatedurl {\\xmlflush {#1}}}[url(\\xmlflush<file://xmlflush> {#1})]}\\endgroup \n<lua output> \n<macro> \\22>:xml:p<file://22%3e:xml:p> \n #1->\\begingroup<file://begingroup> \\xmlfilter<file://xmlfilter> {#1}{.[@xml:lang]/command(xml:language)}\\xmlflush {#1}\n \\endgroup<file://endgroup> \\par<file://par> \n<lua output> \n ...\n\n<initial> \n \n\n", ["lastluaerror"]="", ["lasttexerror"]="Missing number, treated as zero", ["lasttexhelp"]="A number should have been here; I inserted '0'.

Line breaks, \wordright and hyphenation
by kauśika cittūr 26 Oct '21

26 Oct '21

Dear list, In short, my question is: why does \wordright cause a line-break when the line preceding it breaks with hyphenation and does not otherwise? How to avoid it (if at all possible)? I have this delimitedtext instance called 'amnata' defined as below: \definemeasure[amnatamargin][3cm] \definedelimitedtext [amnata] \setupdelimitedtext [amnata] [ left=, right=, leftmargin={\measure{amnatamargin}}, rightmargin={\measure{amnatamargin}}, ] I am using this to quote paragraph(s) of other authors. Since, I also want to indicate where the quote is from, I use this as follows: \startamnata ⋮ \wordright{author} \stopamnata so that the author's name appears at the right-edge of the block. When the penultimate line inside the block breaks without hyphenation, then argument of \wordright is typeset as expected (i.e. in the same line). On the other hand, when the penultimate line inside this block breaks with hyphenation, the argument of \wordright is pushed to the next line even when there is enough space for it on the same line. Here is a sample illustrating this: \startamnata A quote from another author : Suppose that thereisalongwordhere. \wordright{– author} \stopamnata \startamnata A quote from another author : Here, the text does not cause hyphenation in the first line. \wordright{– author} \stopamnata [I have attached the output here as an image] How do I ensure that this does not happen, if that is possible at all? I suppose this is expected behaviour but I am not able to understand why. Thanks, kauśika

Romanization of ancient greek

Dear list, Is there anything in ConTeXt that could help me with automatic romanization of ancient greek words?

Solved: Book setup with LHS-side quotes before chapters/parts, header/footer issues, TOC, etc.
by Gerben Wierda 26 Oct '21

26 Oct '21

Thanks to Wolfgang Schuster and Bruce Horrocks I have now a working solution. I ended up following Bruce’s suggestion of doing a left hand side (LHS) page opposite the first (RHS) chapter or part page differently than using after/before modifications of the \chapter and \part setups as I had been doing years ago (but that book did not have parts and was done in mkii) The modification of \chapter and \part setups with before= and after= never worked in the \component setup in LMTX. Creating a separate command to run immediately before a \chapter or \part, as suggested by Bruce, was simpler and and turned out to be more robust. So, this single file example also works when \components are used. The only issues I have now left are very minimal. In the table of contents, the abstract for a part has some extra whitespace above, which the chapter abstracts don’t have. But that is not really a problem. And getting the part title somewhere more centred on its page is also left as an issue for later. Example file. In a project/component setup: everything before the \starttext goes into the environment file, the rest in the product file. %%% %%% Sections that have a LHS preface with a quote %%% \startsetups SectionLHSPageSetup \page[left] \setupheader[state=empty] \start \startalignment[left,nothyphenated] \startnarrower[4*left] \tf\it \stopsetups \definestartstop [SectionLHSPage] [ before={\setups{SectionLHSPageSetup}}, after={\stopnarrower \stopalignment\stop}] \define[1]\SectionPrequote{\startSectionLHSPage #1\stopSectionLHSPage} %%% %%% part is managed here %%% \defineconversionset [part] [Romannumerals] [numbers] \setuplabeltext[en][partlabel=Part~] \setuphead [part] [sectionsegments=part, bodypartlabel=partlabel, appendixlabel=, sectionconversionset=part, page=yes, header=empty, footer=empty, placehead=yes] \definelist[parttext] \setuplist[parttext][margin=1.3em,pagecommand=\gobbleoneargument] \define[1]\PartAbstract{\writetolist[parttext]{}{\start\itx#1\stop}} %%% %%% chapter is managed here %%% \definetext [chapterfooter] % name [footer] % vertical location [pagenumber] % content \setuplabeltext[en][appendixchapterlabel=Appendix~] \setuphead [chapter] [page=yes, header=empty, bodypartlabel=, appendixlabel=appendixchapterlabel, footer=chapterfooter, sectionsegments=chapter, before={\blank[force,2*big]}, after={\blank[3*big]}] \definelist[chaptertext] \setuplist[chaptertext][margin=1.3em,pagecommand=\gobbleoneargument] \define[1]\ChapterAbstract{\writetolist[chaptertext]{}{\start\itx#1\stop}} \defineresetset [default] [0,0] [1] \setupcombinedlist [content] [list={part,parttext,chapter,chaptertext}] \starttext \startfrontmatter \completecontent \SectionPrequote{If you think good architecture is expensive, try bad architecture\crlf {\tf Brian Foote and Joseph Yoder}} \startchapter[title={One}] \dorecurse{7}{\input tufte \par \input knuth} \stopchapter \stopfrontmatter \startbodymatter \dorecurse{3}{ \SectionPrequote{The world is not \rationals, it is \reals\crlf {\tf Gerben Wierda}} \part{Title title title} \PartAbstract{This is a part abstract.} \dorecurse{2}{ \SectionPrequote{If you think good architecture is expensive, try bad architecture\crlf {\tf Brian Foote and Joseph Yoder}} \startchapter[title={Two}] \ChapterAbstract{This is a chapter abstract.} \dorecurse{5}{\input tufte \par \input knuth} \stopchapter } } \stopbodymatter \startappendices \defineresetset[default][0,1][1] %% reset , chapter, but not part \setuphead[part][number=no] \SectionPrequote{The world is not \rationals, it is \reals\crlf {\tf Gerben Wierda}} \part{Title title title} \PartAbstract{This is a part abstract.} \dorecurse{2}{ \SectionPrequote{If you think good architecture is expensive, try bad architecture\crlf {\tf Brian Foote and Joseph Yoder}} \startchapter[title={Two}] \ChapterAbstract{This is a chapter abstract.} \dorecurse{5}{\input tufte \par \input knuth} \stopchapter } \stopappendices \stoptext In a component setup, a part component may look like this: \startcomponent p_partone \product prd_book \project project_book \SectionPrequote{The world is not \rationals, it is \reals\crlf {\tf Gerben Wierda}} \part{Title title title} \PartAbstract{This is a part abstract for a normal part.} \component c_chapter \component c_chapter \stopcomponent and a chapter component like this: \startcomponent c_chapter \product prd_book \project project_book \starttext \SectionPrequote{If you think good architecture is expensive, try bad architecture\crlf {\tf Brian Foote and Joseph Yoder}} \chapter{An Inconvenient Truth} \ChapterAbstract{This is a chapter abstract.} \setupindenting[next] \placeinitial I{\kap{\bf n the half}} century or so that human kind has had IT, the IT sector has increasingly wrestled with the fact that IT projects often fail in one way or another. \dorecurse{7}{\input tufte \par \input knuth} \stoptext \stopcomponent Gerben Wierda (LinkedIn <https://www.linkedin.com/in/gerbenwierda>) R&A Enterprise Architecture <https://ea.rna.nl/> (main site) Book: Chess and the Art of Enterprise Architecture <https://ea.rna.nl/the-book/> Book: Mastering ArchiMate <https://ea.rna.nl/the-book-edition-iii/>

How do I get the first page of the chapter to display the page number in the footer in this setup?
by Gerben Wierda 25 Oct '21

25 Oct '21

My double-sided layout starts each chapter on a right page with a quote on the opposing left page. I’d like to move the page number of that right page to the footer, but haven’t been able to find how to do this is the documentation. How can I do this? Example: \setuplayout[location=doublesided] \setuppagenumbering[alternative=doublesided] \setuphead[chapter] [page=, sectionsegments=chapter, before={\setups[chapter:before]}, after={\setups[chapter:after]}] \startsetups chapter:before \page[left] \noheaderandfooterlines \startalignment[left,nothyphenated] \startnarrower[4*left] \em \getbuffer[chapter:quote] \stopnarrower \stopalignment \resetsetups[quote:text] \page[right] %\noheaderandfooterlines % I want the enumber in the footer here \blank[force,2*big] \stopsetups \startsetups chapter:after \blank[3*big] \stopsetups \definelist[chaptertext] \setuplist[chaptertext][margin=1.3em,pagecommand=\gobbleoneargument] \define[1]\ChapterAbstract{\writetolist[chaptertext]{}{\start\itx#1\stop}} \starttext \startbuffer [chapter:quote] If you think good architecture is expensive, try bad architecture\crlf {\tf Brian Foote and Joseph Yoder} \stopbuffer \chapter[h:one]{One} \ChapterAbstract{This is chapter abstract 1.} \dorecurse{5}{\input tufte \par \input knuth} \chapter[h:two]{Two} \ChapterAbstract{This is chapter abstract 2.} \dorecurse{5}{\input tufte \par \input knuth} \stoptext Gerben Wierda (LinkedIn <https://www.linkedin.com/in/gerbenwierda>) R&A Enterprise Architecture <https://ea.rna.nl/> (main site) Book: Chess and the Art of Enterprise Architecture <https://ea.rna.nl/the-book/> Book: Mastering ArchiMate <https://ea.rna.nl/the-book-edition-iii/>

Hello all, The example below continues to work with MkIV, but now fails with the most recent (ConTeXt ver: 2021.10.24 21:45) LMTX: \define\DraftOf {Draft of \date} \setupinteraction [date={\DraftOf}] \starttext Fail with LMTX, works with MkIV. \stoptext If the answer is "don't do that" I can find another way to accomplish what this does -- not a big problem. But I do want to point out the difference in behavior. -- Rik

some ConTeXt distribution's Fonts don't work

Hi all, I suppose this is a bug or something unresolved, the following code renders a pdf in LMRoman (lmserif) only: \starttext \startitemize[none] \switchtobodyfont[antykwatorunska] \item font-test 123 \switchtobodyfont[kurier] \item font-test 123 \switchtobodyfont[almfixed] \item font-test 123 \switchtobodyfont[neoeuler] \item font-test 123 \switchtobodyfont[stixtwotext] \item font-test 123 \stopitemize \stoptext How to switch to these fonts? Could this be fixed by default? I'm on ConTeXt ver: 2021.10.21 19:57 LMTX. I've tested all the fonts from https://wiki.contextgarden.net/ConTeXt_distribution%27s_Fonts and these are the only one that do not work. Kind regards and thanks for the great work on context, I just updated and was able to run my previous code resulting in a slightly smaller pdf, which I find great! Andrej

Question on style-italic vs style=italicface
by Rik Kabel 24 Oct '21

24 Oct '21

Hello list mavens, What are the circumstances under which style=italicface should be used instead of style=italic. I note a difference when I define highlighting. I expected to see no difference in the line before and line after the hairline the example below, but see that italicface adapts to nesting, while italic does not: Are there other places where this makes a difference? \setupbodyfontenvironment [default] [em=italicface] %same with italic for this example \definehighlight [emIt] [style=italic] \definehighlight [emIf] [style=italicface] \definehighlight [emEm] [style=\em] \starttext {\em abc {\em def} ghi}: \type{\em} \emph{abc {\emph def} ghi}: \type{\emph} \emEm{abc {\emEm def} ghi}: \type{\emEm \definehighlight[style=\em]} \emIf{abc {\emIf def} ghi}: \type{\emIf \definehighlight[style=italicface]} \hairline \emIt{abc {\emIt def} ghi}: \type{\emIt \definehighlight[style=italic]} \stoptext -- Rik
