bookmarks point to page, not to section start
by Mojca Miklavec 04 Mar '10

04 Mar '10

Hello Hans, I suspect that bookmarks to sections point to pages only, not to the exact position where the sections start. I have another document generated with Word and when I click to it, the viewer (Preview.app) goes straight to section start, while when I generate the document with ConTeXt, it only goes to the page, not to exact section start. The behaviour seems to be the same in both MKII and MKIV (MKII only doesn't respect the accented characters; but I understand the pain of recoding). I'm using the following code to place the bookmarks: \setupinteraction [state=start] \setupinteractionscreen [option=bookmark] \placebookmarks [section,subsection,subsubsection] [section,subsection] \starttext \dorecurse{20}{\section{title} \input tufte} \stoptext Mojca PS: I can send a sample word-generated document off-list for comparison if needed.

Something is wrong with backgrounds
by Andreas Harder 04 Mar '10

04 Mar '10

Hi all, if I compile the following example with the actual beta, the circle is set in foreground … even if the background is not set. \startuseMPgraphic{test} fill fullcircle scaled 5cm withcolor red; \stopuseMPgraphic \defineoverlay[test]{\useMPgraphic{test}} % \setupbackgrounds[page][background=test] \starttext test \stoptext Can someone confirm this or have I overseen something? Greetings, Andreas

Hi Wolfgang, To be serious, what \setbreakpoints[] do? I want to wikify this command. Vyatcheslav

Occasional words sticking out from flush-right
by James Fisher 03 Mar '10

03 Mar '10

Hi, I'm experiencing an issue where, when the width of a block of text is small, the occasional word sticks out from the otherwise flush right. I've previously seen an example of this in an image on the contextgarden wiki, but now can't find it. To reproduce what I mean, compile this with Mark IV: \mainlanguage[en] \usetypescript[palatino] \setupbodyfont[palatino,11pt] \setuppapersize[A4][A4] \setuphead[title][header=empty] \starttext \title{Personal statement} \startcolumns[n=2] This heavily-hyphenated jauntily-formatted flush-left flush-right justified-text paragraph set in a two-column layout and subtly-quirky-but-never-offensive Palatino shouldn't produce out-of-flush sticking-out-like-a-sore-thumb words from the flush-right. \stopcolumns \stoptext In this example, the string 'sticking-out-like-a-sore-thumb' sticks out to approx 3mm from the right edge of the paper. In this situation, I would much prefer that that string is hyphenated, using one of the hyphens already in the string. Based on one other test (in which my text was far less hyphenated than the above), it seems that the hyphenation algorithm refuses to hyphenate strings of words that are already hyphenated. Is this true? If so, is it deliberate? And how do I turn it off? (And do other people agree with me that it's awfully ugly?) Best James Fisher

Using XeTeX results in: ! Undefined control sequence. \PDFversion ->1.\the \pdfminorversion
by James Fisher 03 Mar '10

03 Mar '10

Somewhere in my twists and turns to get Mark IV working today, it appears XeTeX has been broken. Running `texexec --xtx' on any ConTeXt file results in: ! Undefined control sequence. \PDFversion ->1.\the \pdfminorversion All I've been able to find out is that these macros are something to do with PDFTeX. I really don't know where to turn now. I'm running: XeTeX 3.1415926-2.2-0.9995.2 (Web2C 7.5.6) TeXExec | version 6.2.1 - 1997-2009 - PRAGMA ADE/POD MTXrun | current version: 2010.03.02 12:34

no protrusion for hyphen ??
by Steffen Wolfrum 03 Mar '10

03 Mar '10

Hi, I have read there were troubles with |-| in MkIV last year. I found another one: the hyphen set by |-| doesn't get protruded. See example below, please: \startluacode fonts.protrusions.vectors['stpure'] = { [0x002D] = { 0, 0.50 }, -- hyphen } fonts.protrusions.classes['stwpure'] = { vector = 'stpure', factor = 1 } \stopluacode \definefontfeature[default][default] [mode=node,protrusion=stwpure,script=latn]% extend=2,slant=.2, \usetypescript[postscript] \definetypeface[postscript][rm][serif][times][default] \setupbodyfont[postscript,18pt] \setupalign[line,block,hanging] \showframe \starttext \dorecurse{13}{test } test|-|text test \dorecurse{13}{test } test- text test \stoptext Steffen

doifnumberelse
by Hans van der Meer 03 Mar '10

03 Mar '10

The macro \doifnumberelse is not behaving as I would have expected from the description in Taco Hoekwater's article "Context System Macros: part 1: General macros". There I read: The next macro executesa command depending of the outcome of a test on numerals. \doifnumberelse {string} {then ...} {else ...} This text suggest that the the test is on whether "string" as a whole is a number (taken as having digits 0123456789 only, I presume) of contains nondigits and thus isn't a number. However, it seems the macro tests on the first character only. Below follows a minimal example, the context version is: ConTeXt ver: 2010.02.18 14:48 MKIV fmt: 2010.2.20 int: english/ english % test result of \doifnumberelse \def\test#1{#1 is \doifnumberelse{#1}{a number}{not a number}\crlf} \starttext \test{1} % result: 1 is a number \test{a} % result: a is not a number \test{1a} % result: 1a is a number \test{a1} % result: a1 is not a number \stoptext Hans van der Meer

Blank page at end of chapter
by Tom 02 Mar '10

02 Mar '10

I can't figure out how to turn off running headers on the blank pages that are inserted into a document to make the first page of the next chapter start on a right page. I'm probably overlooking something. Tom Benjey 717-258-9733 voice 717-243-0074 fax Twitter: @TomBenjey

METAPOST's superellipse with superness<0.5 does not give a superellipse
by James Fisher 02 Mar '10

02 Mar '10

Hi again, Another METAPOST problem. For the sake of curiosity, I've been looking at and playing with the superellipse() function in plain METAPOST. This is all fine and dandy until I try values of 'superness' less than 0.5, in which case it generates shapes that are seemingly not superellipses. At s=0.5, the function generates a diamond shape -- which, AFAIK, is correct. However, s<0.5, the points of the diamond immediately turn to curves. (My knowledge of superellipses here is just from http://en.wikipedia.org/wiki/Superellipse -- try the image at http://en.wikipedia.org/wiki/File:Lame_anima.gif to see how I expect the shape to change with varying values of superness). Some code follows -- perhaps someone could run it and tell me if, for starters, they get the same as me. (See http://i49.tinypic.com/2ijqatl.jpgfor superellipse() with s=0.3). Best, James % The following is a superellipse function at < http://lists.foundry.supelec.fr/pipermail/metapost-commits/2008-June/000340… >; % I think it's the superellipse function in my copy of METAPOST; it at least has the same behaviour. % It seems to calculate the vertices correctly, but not the way they join (try changing all ... to --). % %def superellipse(expr r,t,l,b,s)= % r ...
