grid+formulas: bug or expected behavior?
by Luca Donetti 26 Jul '19

26 Jul '19

Dear all, I'm typesetting a document with grid layout and some formulas, like in the minimal example below: %%%%%%%%%%%%%%%%%%%%%%%%%%%% \setuplayout[grid=yes] \showgrid \starttext \input knuth %\blank \startformula a = b + c \stopformula \input knuth \stoptext %%%%%%%%%%%%%%%%%%%%%%%%%%%% I don't have any specific need for the alignment of the formula with respect to the grid, but I expect the text below the formula to be on the grid. However, I've not been able to achieve that with any of the layout options described in the latest "details.pdf" manual: in all cases I've tried the text below the formula doesn't "sit" on the grid. While I do not understand this behavior, I've thought that it could be the intended one, because this is what happens in chapter 4 of the "details" manual. Then, I noticed that in older versions of the same manual (for example the one included in texlive 2017) the behavior shown in chapter 4 is the one I expect: the text after formulas is aligned to the grid. So I'm a bit puzzled: should the text after formulas be aligned to the grid or not? Is this a (known?) bug or intended behavior? If this is the expected behavior, I can live with that because by trial and error I found a workaround. If I employ a \blank command before the formula (as in the commented line in the above example), the text after the formula is "correctly" aligned. Thank you in advance. LD

Well, I mentioned 'makeindex' in the context of the tool which cannot properly handle Unicode, afaik. Mojca> What features exactly do you miss? I'm not sure if indexing-feature in ConTeXt allow me to use English, Croatian and Sanskrit diacritics (not Devanagari) all in one document and define that I want e.g. that \'{s}, \d{s} has to be sorted under 'Š' ? In short, xindy allows one to define his own sort-rules. Mojca> It makes no sense to discuss distributing something before it can Mojca> be used with ConTeXt.) Right, that's why also asked "Now I'm interested how is support for Xindy in ConTeXt" hoping that the context-distribution list has enough knowledgeable people able to answer it. Excuse me for the noise...redirecting to other list... Sincerely, Gour -- Gour | Zagreb, Croatia | GPG key: D19DB797 ----------------------------------------------------------------

Dear sirs, Is there a way to make crosswords or word puzzles in context? In my hippocampus I have a vague idea that this has already been tried, but I can't find this code anymore. Have a great day Jorge

mkiv MathML bug?
by Duncan Hothersall 27 Jun '19

27 Jun '19

I'm not sure this is something more general in the MathML module or if it's specific to the vertical bar in this particular context, but here is a minimal example showing that the "=0" at the end of the equation is disappearing: \usemodule[mathml] \starttext \xmlprocessdata{}{<imath> <math xmlns='http://www.w3.org/1998/Math/MathML'> <mi>A</mi> <mfenced open="(" close=")" separators=""> <mi>B</mi> <mo>|</mo> <mi>C</mi> </mfenced> <mo>=</mo> <mn>0</mn> </math> </imath>}{} \stoptext And here is a workaround using <mtext> instead of <mo> for the vertical bar which makes the "=0" magically reappear again: \usemodule[mathml] \starttext \xmlprocessdata{}{<imath> <math xmlns='http://www.w3.org/1998/Math/MathML'> <mi>A</mi> <mfenced open="(" close=")" separators=""> <mi>B</mi> <mtext>|</mtext> <mi>C</mi> </mfenced> <mo>=</mo> <mn>0</mn> </math> </imath>}{} \stoptext Flagged up mainly in case it is a bigger problem than just vertical bars in this specific context. Thanks, Duncan

Strange behavior in somewhat complex layout
by Andres Conrado Montoya 27 Jun '19

27 Jun '19

Hello list, I'm trying to make something using bits and examples found here and elsewhere, but I'm hitting a wall. I know there's a flawed logic in my approach, but I can't figure it out. Any help is appreciated. Expected behavior of the following MWE: When starting a new chapter, check if the page is even (left page), if so, fill it with color, and start the chapter in the next odd page (right page), removing the header but leaving the footer in that start-chapter page; and if this is a start-chapter page, use a specific graphic overlay for the page, but if if not (if its a regular page), use another graphic. Result: The header still appears in the start-chapter page, if it comes after the color filled page. But, if the start-chapter page comes after a regular (even) page, everything works as expected (no color-filled page, no header in the start-chapter page). MWE: %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% START MWE \definecolor[rojo][h=ED553B] \definehighlight[rojo][color=rojo] \startMPinclusions numeric u ; u := 1.125pt ; numeric i ; i := 0.125in ; string prevChapterTitle, currentChapterTitle; prevChapterTitle := ""; currentChapterTitle := ""; \stopMPinclusions \startuseMPgraphic{page:background} StartPage; currentChapterTitle := "\namedstructurevariable{chapter}{title}"; if currentChapterTitle <> prevChapterTitle : fill (topboundary Page -- cycle) enlarged(0,8i) shifted (0,-4i) withcolor transparent(4, 0.2, \MPcolor{rojo}) ; fill (bottomboundary Page -- cycle) enlarged(0,1u) shifted (0,6i) withcolor \MPcolor{rojo} ; prevChapterTitle := currentChapterTitle ; else: fill (topboundary Page -- cycle) enlarged(0,0.25u) shifted (0,-7i+3u) withcolor \MPcolor{rojo} ; fill (bottomboundary Page -- cycle) enlarged(0,0.25u) shifted (0,6i) withcolor \MPcolor{rojo} ; fi; StopPage; \stopuseMPgraphic \defineoverlay [chapter:background] [\useMPgraphic{page:background}] \setupbackgrounds[page][background=chapter:background] \definepagebreak[firstpagebreak][yes,header] \startsetups [chapter:before] \doifoddpageelse {} {\pushbackground[page] \setupbackgrounds[page][background=color,backgroundcolor=rojo] \page[yes,right] \popbackground} \stopsetups \setuphead[chapter] [width=20em, before=\directsetup{chapter:before}, align={flushleft,nothyphenated,verytolerant}, style={\tfd\sansbold}, header=empty, page=yes, commandbefore={\blank[1.75in]}, after={\blackrule[color=rojo,height=4pt,width=6em]\blank[1.25in]}] \setuppagenumbering[alternative=doublesided,location=] \setupheadertexts [] [{{\small\sans\getmarking[chapter]}}] [{{\small\sans\getmarking[chapter]}}] [] \setupfootertexts [] [{\rojo{\small\sansbold\pagenumber}}] [{\rojo{\small\sansbold\pagenumber}}] [] \starttext \dorecurse{4}{% \startchapter[title={A chapter with a really long, long title}] \dorecurse{9}{\input{tufte}} \stopchapter \startchapter[title={A different chapter with a really long, long title}] \dorecurse{6}{\input{tufte}} \stopchapter} \stoptext %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% STOP MWE Thank you for your time.

IEEE Citation Style
by Julian Gompper 27 Jun '19

27 Jun '19

Hello everyone, I am fairly new on the mailing list, so I apologize if this topic has already been talked about in the past. I am currently writing a technical documentation with ConTeXt, and I would like to use the IEEE citation style. As I have read on the wiki ( https://wiki.contextgarden.net/Bibliography_mkiv#rendering ) and in Chapter 4.2 of "BIBLIOGRAPHIES THE CONTEXT WAY" ( http://pragma-ade.nl/general/manuals/mkiv-publications.pdf ), only apa and aps styles are available as of now. I have found this file on github, although it does not seem to work and it was last created in July 2017 ( https://gist.github.com/adityam/afda949f76676055e7906679599ec937 ). Is there a more up-to-date version available, or should I try to make my own? Best regards, Julian

issue with italic correction (again)
by Pablo Rodriguez 27 Jun '19

27 Jun '19

Dear list, [sorry for insisting, but I have the impression that the previous version of this message went unnoticed.] I have the following sample: \def\DesiredFont{TeX Gyre Termes} \definefontfeature[italic][itlc=yes,textitalics=yes] \setupitaliccorrection[global, always] \definefontfamily [mainface] [rm] [\DesiredFont] \definefontfamily [mainface_corrected] [rm] [\DesiredFont] [features={italic}] \setupbodyfont[mainface] \setupitaliccorrection[global,always] \starttext \startbuffer[chars] \startTEXpage[offset=1em] \dorecurse{26} {\setupbodyfont[mainface]% [{\em \recurselevel}] [{\em \characters{\recurselevel}}] [{\em \Characters{\recurselevel}}] ({\em \characters{\recurselevel}}) ({\em \Characters{\recurselevel}}) \hfill \setupbodyfont[mainface_corrected] [{\em \recurselevel}] [{\em \characters{\recurselevel}}] [{\em \Characters{\recurselevel}}] ({\em \characters{\recurselevel}}) ({\em \Characters{\recurselevel}}) \par} \stopTEXpage \stopbuffer \getbuffer[chars] \def\DesiredFont{TeX Gyre Pagella} \getbuffer[chars] \stoptext This shows that sequences such as ({\em f}) are corrected with the closing parenthesis, but not with the opening one. Wouldn’t it be possible that italic correction could be enabled also before the italic glyph(s)? BTW, I wonder why the second definition of \DesiredFont doesn’t change the font for the buffer used after it. Many thanks for your help, Pablo -- http://www.ousia.tk

inline fractions
by Alan Bowen 26 Jun '19

26 Jun '19

The following mwe \definefontfeature[fraction][frac=yes] \definehighlight[textfraction][style={\feature[+][fraction]}] \starttext a fraction \m{\frac{1}{n}}, \textfraction{1/n}, \vulgarfraction{1}{n} in the text \stoptext works for all but \textfraction in the latest beta (luatex, luametatex). Has something changed or have I missed something? Alan
