Suppress chapter title marking on blank page after chapter
by Rik Kabel 14 Oct '17

14 Oct '17

In a doublesided document, how can I suppress the chapter title marking in the header of the blank page that follows a chapter in which the text ends on a recto page? I do not want to suppress the header. The following example shows the problem on pages 4 and 6. I notice that the Contents chapter does not exhibit this problem (page 2). But checking the source for /completecontent/ provides no useful information. Indeed, when I use /title/ instead of /chapter/, as done in strc-lis.mkvi, page 2 gets the marking as well! \setuppagenumbering [alternative=doublesided,location=] \setupheadertexts [][{\it\getmarking[section]}] [{\it\getmarking[chapter]}][] \setupheadertexts [margin] [] [{\inframed[frame=off,leftframe=on,loffset=1em] {\userpage}}] [{\inframed[frame=off,rightframe=on,roffset=1em] {\userpage}}] [] \setuphead [chapter] [header=nomarking] \startbuffer[testt] \startchapter[title=Chapter] \startparagraph \input ward \stopparagraph \dorecurse{\numexpr2*\recurselevel\relax} {\startsection[title=Section] \startparagraph \input ward \stopparagraph \stopsection} \stopchapter \stopbuffer \starttext \completecontent \dorecurse{3}{\getbuffer[testt]} \startchapter[title={Chapter Last}] \input knuth \stopchapter \stoptext -- Rik

up and down arrows
by Wim 13 Oct '17

13 Oct '17

Dear all, Can anybody explain me why I can't use TeX constructs like: \left\downarrow \vcenter to 1.5cm{}\right. \Big\downarrow in mathmode in Context. It doesn't work with other downward or upward arrows either. Or are there alternatives in Context? Thank you, Wim W. Wilhelm

changed behavior in --result
by Pablo Rodriguez 12 Oct '17

Dear list, invoking latest beta (2017.10.10 12:00) with --result="/home/ousia/%e-2UP.pdf" gives the following error message: results are to be on the running path, not on '/home/ousia', ignoring --result This worked fine untill recently. Is there another way to specify the directory for the output file? Many thanks for your help, Pablo -- http://www.ousia.tk

issue with external image and PDF/A-3a
by Pablo Rodriguez 10 Oct '17

10 Oct '17

Dear list, I have this minimal sample: \setupbackend [format=PDF/A-3a, intent=sRGB IEC61966-2.1, profile={sRGB.icc,default_gray.icc}, level=0] \setuptagging[state=start] \setupcolors[cmyk=no] \startTEXpage[offset=1em] \externalfigure[transparent] \stopTEXpage \stoptext The external figure is available from http://pdf.ousia.tk/transparent.pdf (and output file at http://pdf.ousia.tk/transparent-pdf-a-3a.pdf) Using veraPDF (http://verapdf.org/) the output document doesn’t comply with the validation profile requirements. As Luigi wisely predicted, external images may be problematic. I get one error, because of the color of the external figure: https://github.com/veraPDF/veraPDF-validation-profiles/wiki/PDFA-Parts-2-an…. The PDF object in question is the following: 12 0 obj << /Type /XObject /Subtype /Form /FormType 1 /BBox [ 0 0 316.896 215.5669 ] /Group << /Type /Group /S /Transparency /I true /CS /DeviceRGB >> /Resources 21 0 R /Length 71 >> stream q 0.188235 0.392157 0 rg /a0 gs 28.348 187.219 260.203 -158.871 re f Q endstream endobj Well, this is a minimal sample, but my real document is much bigger. Is there any way to convert the stream to something that ConTeXt can handle directly? Many thanks for your help, Pablo -- http://www.ousia.tk

ICC profiles for \externalfigure
by Pablo Rodriguez 10 Oct '17

10 Oct '17

Dear Luigi and Hans, I have the following sample: \setupbackend [format=PDF/A-3a, intent=sRGB IEC61966-2.1, profile={sRGB.icc,default_gray.icc}, level=0] \setuptagging[state=start] \setupcolors[cmyk=no, pagecolormodel=auto] \setupexternalfigure[location=default] \startTEXpage[offset=1em, align=center] \dontleavehmode \externalfigure[cow-black] \dontleavehmode \externalfigure[cow-brown] \dontleavehmode \externalfigure[basic-figures.pdf][scale=200] \stopTEXpage \stoptext The third external figure is found at http://pdf.ousia.tk/basic-figures.pdf. I included it, since it adds a transparency group (and I guess this might be relevant). PDF/A-3a validation (http://verapdf.org) warns about XObjects not having any ICC profile. Would it be possible to add the "profile" key to \externalfigure, so that each figure may have its own profile (or the reference to the profile) added? Many thanks for your help, Pablo -- http://www.ousia.tk

How to add a font folder with local fonts?
by Ulrike Fischer 10 Oct '17

10 Oct '17

How can I add a simple folder (not a texmf tree) with opentype or truetype fonts to the search path of context? I have tried with a local texmfcnf.lua and return { content = { variables = { OPENTYPEFONTS = ".;D:/myfonts//;$TEXMF/fonts/{data,opentype}//;$OSFONTDIR", }, }, } but while `mtxrun --expand-var` reports the new value the folder is ignored when I run `mtxrun --script fonts --reload`. (Side remark: I found some small problems in mtxrun while testing: mtxrun and also the wiki give as an example mtxrun --script font --list somename but correct would imho be mtxrun --script fonts --list somename Also I would have expected that "mtxrun --script base --expand-var VAR" works, but actually I needed "mtxrun --expand-var VAR".) -- Ulrike Fischer http://www.troubleshooting-tex.de/

Dear all, I have something like \defineenumeration [test] [text={Test:}, headstyle=bold, number=no, before={\startcolor[red]}, after={\stopcolor}, style=normal, title=no ] \starttext \input{knuth} \starttest \input{tufte} \stoptest \input{knuth} \stoptext When I comment out the before/after, I get paragraph breaks before and after the enumeration. How can I have them with the before/after? Thanks, Matthias

Lua problem with tagging or setups
by Rik Kabel 09 Oct '17

09 Oct '17

Consider the following almost-minimal example: \setuptagging [state=start] \setuppapersize [A6] \setupexternalfigures[location=default] \definemakeup [cover4][page=left,doublesided=no] \definelayer [isbn][width=\pagewidth,height=\pageheight] \define \Title {A Primer on Omphaloskepsis} \startsetups [placeisbn] \setlayer [isbn][preset=rightbottom,hoffset=5mm,voffset=5mm] {\externalfigure[cow.pdf][width=3cm]} \stopsetups \starttext \setupbackgrounds [page][setups=placeisbn,background=isbn] \startmakeup [cover4] \scale [width=\textwidth] {\red \Title} \stopmakeup \stoptext For me (Win64, current standalone beta), compilation halts with: lua error > lua error on line 4 in file C://Users/rik/Desktop/xxx.tex: ...ext/tex/texmf-context/tex/context/base/mkiv/back-exp.lua:823: attempt to index local 'spec' (a nil value) stack traceback: ...ext/tex/texmf-context/tex/context/base/mkiv/back-exp.lua:823: in function <...ext/tex/texmf-context/tex/conte xt/base/mkiv/back-exp.lua:818> (It always points to line 4 of the file, no matter the file.) When the halt is answered with a CR, the processing runs to completion with no apparent errors. When the first line is removed, or the state set to stop, compilation completes normally. When the content of the setup (the two-line \setlayer) is moved out of the setup, compilation completes normally (without regard to tagging). (I use a setup here because, in the real work on which this is based, there are other items in the layer that cannot be properly handled until after \starttext processing. -- Rik

abbreviations: \infull always in small caps
by Henning Hraban Ramm 09 Oct '17

09 Oct '17

Ahoi, I’m trying to employ the synonyms mechanism for abbreviations, as documented: \setupsynonyms [style=italic, headstyle=bold, titlestyle=normal, synonymstyle=normal] \abbreviation{Abt.}{Abteilung} \abbreviation{ADN}{Allgemeiner Deutscher Nachrichtendienst} \abbreviation{AFL}{American Federation of Labor} \abbreviation{ANC}{African National Congress} \abbreviation{AV}{Auslandsvertretung} \abbreviation{BArch}{Bundesarchiv} \starttext \placelistofabbreviations[criterium=all] \infull{AV} \infull{AFL} \stoptext The result of \infull is always in small caps, and I don’t like that. I couldn’t find its definition in the source* nor a setup command. * http://source.contextgarden.net/tex/context/base/mkiv/strc-syn.mkiv?search=… Greetlings, Hraban --- http://www.fiee.net http://wiki.contextgarden.net GPG Key ID 1C9B22FD
