starttexdefinition error in standalone, works in TL2013
by Rik Kabel 12 Mar '14

12 Mar '14

The following code processes cleanly under TL2013 and fails with ConTeXt ver: 2014.02.14 17:07 MKIV beta fmt: 2014.2.16 int: english/english. I suspect a regression, but I am also open to being told that I am doing things incorrectly. I also notice that it fails (even under TL2013) if a space is inserted after [#SETUP] in the doTrans intro. I thought that spaces should be allowed in \starttexdefinition -- is this only in the body and not the parameter description? % macros=mkvi \showframe \let\EndTranslation\relax \starttexdefinition Trans \dosingleempty\doTrans \stoptexdefinition % The following should work, but fails with current beta \starttexdefinition doTrans [#SETUP]#TRANSLATION\EndTranslation \language[en] \doifsomething{#1}{\getparameters[TR][setup=,#SETUP]\TRsetup} \noindentation\blank[halfline] (\,\ignorespaces#TRANSLATION\removeunwantedspaces\,) \stoptexdefinition \starttexdefinition Translation \dosingleempty\doTranslation \stoptexdefinition % This version works with both Texlive and current standalone beta \def\doTranslation[#SETUP]#TRANSLATION\EndTranslation% {\language[en]% \doifsomething{#SETUP}% {\getparameters[TR][setup=,#SETUP]\TRsetup}% \noindentation\blank[halfline]% (\,\ignorespaces#TRANSLATION\removeunwantedspaces\,)% } \starttext Translation using \tex{def}{\tex{doTranslation}} works both with TL2013 and current beta. \Translation[language=en] It betrays a slow-witted mentality to pursue the streams, but not to see the sources of things. \EndTranslation \blank Translation using \tex{starttexdef doTrans} fails with current beta. \Trans[language=en] It betrays a slow-witted mentality to pursue the streams, but not to see the sources of things. \EndTranslation \stoptext -- Rik Kabel

MP bounding box

confusion about expansion
by Lars Huttar 12 Mar '14

12 Mar '14

Hello, I've got a running page head like this in my document: \def\CurrentUser{\cldcontext{os.resultof"whoami"}} \def\Markname { Compiled \date by \CurrentUser \LUATEX +\ConTeXt\ \contextversion } and later: \setlayer[cropmark][preset=lefttop,x=3cm,y=-1.5\lineheight]{\Markname} But when I run this, I get a UCS error that seems to indicate that the *result* of \CurrentUser ("waxhaw\huttar") is getting parsed as a command sequence. Here's the error: ! Undefined control sequence. 1 >> % see ConTeXt wiki http://wiki.contextgarden.net/Imposition#Cut_marks 2 3 %% TODO: make sure this doesn't reevaluate every time 4 %% the command sequence is used! 5 \define\CurrentUser{\cldcontext{os.resultof"whoami"}} 6 7 \def\Markname { Compiled \date by \CurrentUser \LUATEX +\ConTeXt\ \conte xtversion.

I tried (somewhat blindly) changing \def to \define, but it didn't make any difference. At the same time, I want to make sure that the processor won't be making an OS system call to "whoami" every time \CurrentUser is evaluated: I want it to happen only once, when \CurrentUser is defined. Here is my complete working example: \def\CurrentUser{\cldcontext{os.resultof"whoami"}} \def\Markname { Compiled \date by \CurrentUser \LUATEX +\ConTeXt\ \contextversion. } \setuplayout[location=middle,marking=on] \definelayer[cropmark][state=repeat,width=\paperwidth,height=\paperheight] \setupbackgrounds[page][background=cropmark] \setlayer[cropmark][preset=lefttop,x=3cm,y=-1.5\lineheight]{\Markname} \starttext Foo \stoptext Thanks for any help.

Bugs in XML export (for ePub)
by Henning Hraban Ramm 12 Mar '14

12 Mar '14

Hi again. I understand you don’t want to export some arbitrary (X)HTML. That’s fine, I can make my own XSLT. And I’m glad that \setupexport doesn’t kill hyphenation any more. But there are serious errors in export, that have nothing to do with „there’s no usable standard“. [1] root node First, the exported XML file lacks a root node! Just call it <export> or <context> or whatever you like, but it MUST be there, otherwise it’s no wellformed XML. If I enable xhtml mode like \setupbackend[export=export.xml,xhtml=yes] the exported file stops after a few lines. If I set xhtml=somefile.xhtml, I get the broken export.xml and the complete somefile.xhtml, so I guess xhtml=yes causes overwriting the complete file with the incomplete one. As far as I remember previous discussions, this incomplete content is caused by the project structure (using project, product, environment); from single file it seemed to work, at least at that time, I didn’t check. Since xhtml mode doesn’t do anything useful anyway, I can just drop the setting. [2] metadata The metadata from \setupexport is completely ignored. The metadata from \settaggedmetadata is exported just fine, but it ends up within the first block of the first page, if that’s not empty. e.g. my text starts with \startlines Title etc. \stoplines, then <metadata><metavariable> etc. is exported within <lines>. If I add something like \startparagraph \stopparagraph to contain the metadata, it disappears. Of course I don’t want to add something visible (then it works again). [3] cover picture The firstpage key of setupexport is supposed to define a cover picture for the ePub, but it doesn’t do anything, as far as I can tell. Or is something wrong in: \setupexport[firstpage={img/cover.jpg}] ? [4] delimited If \quotation{} contains more than one paragraph (in my case it’s a quote), the <delimited detail="quotation“> is ended after the first paragraph. (As always, working with latest MkIV beta on OSX.) Greetlings, Hraban --- http://www.fiee.net/texnique/ http://wiki.contextgarden.net https://www.cacert.org (I'm an assurer)

\about disables \setupnote[footnote][split=strict]
by Pablo Rodriguez 11 Mar '14

11 Mar '14

Dear list, I have just accidentally noted that \about disables the option [split=strict] in \setupnote. Here is a sample: \mainlanguage[es] \setuppapersize[A6] \setupnote[footnote][split=strict] \starttext \section[espacios]{Espacios} \section[parrafos]{Párrafos} \dorecurse{5}{Esta es una frase.\par} En el preámbulo sólo existen órdenes. Antes de \tex{starttext}, no debe haber texto, únicamente órdenes de configuración. Cada orden puede formar un parrafo, esto es, puede contener saltos de línea, pero no una línea en blanco. Y no debemos mezclar órdenes distintas en la misma línea. En el preámbulo se aplica también lo dicho en las secciones %~ «Espacios» y «Párrafos». \about[espacios] y \about[parrafos]. Entre diferentes órdenes, puede haber tantos saltos de línea como queramos\footnote{En este caso, ni siquiera tiene que haber una línea en blanco. La única regla es la legibilidad de nuestro código. Es especialmente importante, porque las órdenes de configuración del preámbulo son más difíciles de leer que el texto mezclado con órdenes.}. Esta es otra frase. \stoptext If you comment the \about line and uncomment the previous line, you will see the different behavior. Note reference in body shouldn’t have the footnote in a different page. I’m afraid this is a bug. Would anyone be so kind to confirm it? Many thanks for your help, Pablo -- http://www.ousia.tk

struggling with section headers
by Henning Hraban Ramm 11 Mar '14

11 Mar '14

Hi again, I got a few different problems related to my section headers. I use \startsection[title={Something}] … \stopsection, but not \startparagraph, in case that matters. (Latest MkIV beta on OSX.) I need grid typesetting and use the same line spacing for body text and section headers (body text is 9pt, section headers are 11pt, interlinespace is 12pt). But as soon as I enable grid typesetting, there’s at least one line of space after the header - doesn’t hurt, but my setup says: \setupheads[ align={right,nothyphenated}, tolerance=verytolerant, grid=line, number=no] \setuphead[section][ page=no, style={\SectionFont}, before={\blank\vfil}, after={\relax}, interlinespace=12pt] Headers should stick with their (following) paragraph, but they tend to stick with the previous line. I.e. there are several pages that end somewhere in the middle, but their last line is on the next page above the section title. I don’t want page=yes, but the section should start on a new page rather than with just the title at the foot. If a page starts with a header, there should be no additional space above it. Did I miss some obvious setup? Greetlings, Hraban --- http://www.fiee.net/texnique/ http://wiki.contextgarden.net https://www.cacert.org (I'm an assurer)
