aligning \placetable with bidi
by Idris Samawi Hamid ادريس سماوي ح امد 17 Nov '14

Dear gang, In the following, we middle align both \placetable's: ================ \setupbodyfont[tt] \definefont[ALM][file:almfixed.otf*arabic at 12pt] \setupdirections[bidi=global] \setupxtable[width=1in] \showframe \starttext \startalignment[middle] \ALM \placetable[middle,none]{} {\startxtable \startxrow \startxcell Text 1 \stopxcell \startxcell[align=r2l] النص ١ \stopxcell \stopxrow \stopxtable} \placetable[middle,none]{} {\righttoleft \startxtable \startxrow \startxcell[align=r2l] النص ١ \stopxcell \startxcell Text 1 \stopxcell \stopxrow \stopxtable} \stopalignment \stoptext ================ Only the first \placetable is aligned correctly; how do we get the second one -- \righttoleft table -- middle aligned? See attached. Best wishes Idris -- Idris Samawi Hamid Professor of Philosophy Colorado State University Fort Collins, CO 80523

Is there any way to construct "Set-OCG-State Actions" with ConTeXt? (See Section 8.5 Actions in the PDF Reference.) I admit that this is an advanced feature of PDF and that most viewers apart from the Adobe Reader are not capable of handling OCGs correctly. Kind Regards, Christoph

Use of a layer for a letterhead
by jdh 17 Nov '14

17 Nov '14

I have created a letterhead layer, which works well for the first page of a multi-page document. I want it to be repeated for each page of a document. How can that be done or does anyone have any pointers or tips on how I can do that? Thank You

Support of PDF Optional Content Groups (Layers)
by Christoph Reller 16 Nov '14

16 Nov '14

Hi, Has ConTeXt any support for producing a PDF with "optional content groups" (OCGs)? In Adobe's jargon OCGs are also known as "layers" (not to confuse with layers in ConTeXt). See Section "4.10.2 Making Graphical Content Optional" in the PDF Reference 1.7 available at http://wwwimages.adobe.com/content/dam/Adobe/en/devnet/pdf/pdfs/pdf_referen… I cannot find anything on the Wiki nor in the ntg-context emails and grepping through the source code for "ocg" does not give reasonable results. Cheers, Christoph

extra unwanted interline space in list
by Pablo Rodriguez 16 Nov '14

16 Nov '14

Dear list, I have the following sample: \starttext \startitemize[n] \item \input zapf \item \startitemize[a] \item \input knuth \stopitemize \stopitemize \stoptext For some strange reason, the first line from 2.a. has an extra interline space after it. Is this a bug or am I missing something? Many thanks for your help, Pablo -- http://www.ousia.tk

Macros in \start-stopTABLE
by Idris Samawi Hamid ادريس سماوي ح امد 16 Nov '14

16 Nov '14

Dear gang, In the following, the first table works and the second one does not: ===================== \setupbodyfont[tt] \definefont[ALM][file:almfixed.otf*arabic at 12pt] \setupdirections[bidi=global] \define\NCR{\NC \righttoleft \ } \define\NCL{\NC \lefttoright \ } \setupTABLE[c][each][width=1in] \starttext \ALM \placetable[right,none]{} {\startTABLE \NC Text 1 \NC \righttoleft النص 1 \NC\NR \stopTABLE} \placetable[right,none]{} {\startTABLE \NC Text 2 \NCR النص 2 \NC\NR \stopTABLE} \stopalignment ===================== gives "I've run across a `}' that doesn't seem to match anything." What do I need to do to get this macro right here? Best wishes Idris -- Idris Samawi Hamid Professor of Philosophy Colorado State University Fort Collins, CO 80523

IMHO there is a bug in itemgrops
by Vasiliy Chirkov 16 Nov '14

16 Nov '14

Minimal example: \starttext \defineitemgroup[Enum][levels=3] \setupitemgroup[Enum][each][fit][symbol=n] \setupitemgroup[Enum][1][stopper={}] \setupitemgroup[Enum][2][stopper={***}] \setupitemgroup[Enum][3][stopper={******}] \startEnum \item item 1 \startEnum \item item 1.1 \startEnum \item item 1.1.1 \item item 1.1.2 \stopEnum \item item 1.2 \stopEnum \item item 2 \stopEnum \stoptext When option 'fit' is used with nested lists, calculated max item widths are saved in reverse order. Maxitemwidths are saved at first pass in \stopitemgrup in reverse order, while are read at second pass in \startitem grpoup in sequental order. Am i right? Best regards, Vasiliy

\xmlinlineverbatim and \xmldisplayverbatim
by Pablo Rodriguez 16 Nov '14

16 Nov '14

Dear list, I’m totally new to processing XML with MkIV. I have read some examples and documents from Thomas. And I have started “Dealing with XML in ConTeXt MkIV” from Hans. >From the documentation, one could state that the (X)HTML tags <code> and <pre> are to be handled with \xmlinlineverbatim and \xmldisplayverbatim. Well, this works fine (although with an undersired output): \startxmlsetups xml:code \xmldisplayverbatim{#1} \stopxmlsetups But replacing \xmldisplayverbatim with \xmlinlineverbatim gives an error. According to the information from http://pragma-ade.com/general/manuals/xml-mkiv.pdf#page=19, it should work. What am I doing wrong here? Many thanks for your help, Pablo XML file: <code>code</code> Environment file: \startxmlsetups xml:test \xmlsetsetup{\xmldocument}{*}{-} \xmlsetsetup{\xmldocument}{code|}{xml:*} \stopxmlsetups \xmlregistersetup{xml:test} \startxmlsetups xml:code \xmlinlineerbatim{#1} \stopxmlsetups -- http://www.ousia.tk

Contents again
by Gerben Wierda 15 Nov '14

15 Nov '14

I’ve got \start \switchtobodyfont[9pt] \completecontent[level=chapter] \stop to keep the Table of Contents on one page. But with one more chapter, it is now again spread over two. There is however a lot of whitespace between entries. Can I make the vertical whitespace between entries smaller? G
