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

Re: [NTG-context] is it useful to use the option "--fonts=all" when running first-setup-sh?
by Andres Conrado 26 Jun '19

26 Jun '19

Tank you very much Pablo. I'll try that. They are proper latex fonts, tho, so I'm no sure that will do. I also have a background i humanities and book design, but I'm now making math books, go figure. It's very interesting from a typographic point of view. Now I'm more interested in seeing what happens with the last code I sent here, in another message... "Strange behavior in somewhat complex layout" Maybe nobody noticed it. I hope I can figure that out.

luatex-fonts-merged.lua broken?
by Ulrike Fischer 25 Jun '19

25 Jun '19

Hans, we think that luatex-fonts-merged.lua is broken: It contains in line 8594 return characters.indicgroups (from luatex-basics-chr.lua) and such a return statement is a problem in a merged file. -- Ulrike Fischer https://www.troubleshooting-tex.de/

Re: [NTG-context] ntg-context Digest, Vol 180, Issue 23
by Andres Conrado 25 Jun '19

25 Jun '19

Thanks, Pablo. I am assuming I need to have Utopia installed in my usual font folder. I tried with Erewhon (I have otf files for that) and it works. Thank you. In a related note, is there any reasonable way to use the latex math font *Math Times Pro 2* (https://www.pctex.com/mtpro2.html)? I know a latex user who bought that font and I wonder if I can convince him to get on the ConTeXt boat.
