Problem with embedding code TikZ code

In the code below, I do not understand why the label "Arbre 2" does not have the color you want, that is to say the same as the label "Arbre 1".

Hi all, I updated ConTeXt today (version 29-08-2014) I need to compile a document with page impositioning. But it seems that arranging is not working i.e. the command is just ignored. What to do? Kind regards Willi

Chapter precis
by Werner Hintze 30 Aug '14

30 Aug '14

Some old fashioned novels have a chapter précis in the table of contents. In Latex exists the command \chapterprecis to put the text at the beginning of the chapter and in the able of contents. I thought, I can realize this in ConTeXt with \writebetweenlist[chapter]{XYZ} or with \weitetolist[chapter]{XYZ} But both produce only a fatal error. What’s wrong here? Thanks für help! WH

E-books and XML.
by john Culleton 30 Aug '14

30 Aug '14

Context is moving toward accepting XML input, although the filtering process is necessarily complex. But what is also needed is a version of Context that produces well formed XML as an output. That would be a step toward producing a dual purpose document with Context, for print and for e-book use. Context users have invested time, often years, in learning how to write Context code. Writing XML is a whole other skillset, comparable to writing xhtml. So is writing a Context to XML converter a possibility? A probability? The commercial program InDesign already has such a capability. -- John Culleton Wexford Press Free list of books for self-publishers: http://wexfordpress.net/shortlist.html PDF e-book: "Create Book Covers with Scribus" available at http://www.booklocker.com/books/4055.html

hyperlinks with special characters
by Prashanth N Rao 29 Aug '14

29 Aug '14

I have already asked this question on Stackexchange. It appears that no one who has seen the question knows an answer. I figure I'll ask here too, just to cover all bases. I need to link to some online resources in my PDF file. Based on the official documentation, I have written: > \useURL[dbdk] [http://dbpedia.org/page/The_Dark_Knight_(film)] [] [it's link to DBPedia] > > Lorem ipsum \goto{the LinkedMDB.org entry on The Dark Knight}[url(http://data.linkedmdb.org/page/film/6224)], and \from[dbdk] dolor sit amet. Note my code for the link to DBpedia: I had to write it in this convoluted way, instead of using my preferred \goto, because the link has the special characters, `(` and `)`. These characters interfered with `url()`. I can't use HTML's URL encoding scheme because the `%`s interfere with TeX. Is there another escape code format in ConTeXt for use within `\goto{...}[url(...)]`? Using the suggestion by @phg, I tried the following: > \startasciimode > Lorem ipsum \goto{the LinkedMDB.org entry on The Dark Knight}[url(http://data.linkedmdb.org/page/film/6224)], and \goto{it's link to DBPedia}[url(http://dbpedia.org/page/The_Dark_Knight_%28film%29)] dolor sit amet. > \stopasciimode I still had to use escape codes, `%28` and `%29`, to keep it from interfering with url(). It turns out that DBpedia does not like these codes, and requires the actual characters. Is there another way I put them in `\goto{...}[url(...)]`? Thanks! Prash

Startparagraph oddities
by Rik Kabel 29 Aug '14

29 Aug '14

There appears to be an inconsistency in the implementation of \startparagraph. When it is used with one argument (or two by my reading of the source) it defines \stopparagraph with a terminal \endgraf, yet with no arguments this is not done. Strangely (to me) it also appears to insert a line-break before \startparagraph[]. The example below demonstrates these issues. I would expect to have \endgraf inserted with each \stopparagraph regardless of the argument count. There is also a wiki issue with overloading of the command name \startparagraph. The existing command entry points to the paragraphs mechanism for setting up parallel paragraphs in columns. There is also a \startParagraph command described for the t-pararef module. There is no mention of \startparagraph in the \startsection page, which might be an appropriate place. Perhaps some Wikipedia-style disambiguation mechanism is needed. \starttext \startparagraph One \stopparagraph \startparagraph Twee \stopparagraph \startparagraph Drie \stopparagraph \startparagraph[] One \stopparagraph \startparagraph Twee \stopparagraph \startparagraph Drie \stopparagraph \stoptext -- Rik Kabel

XML, XHTML, and HTML export issue with & in URL
by Rik Kabel 28 Aug '14

28 Aug '14

With the following example, the output xml writer fails to properly transform & to the html entity & in some urls; \hyphenatedurl works fine. The generated xhtml and html files have this problem as well as more issues with the transformation, including what appears to be mistaken transformation of < and > to html entities and unbalanced <link> tags. When a URL without & is used, the problems do not appear. I used the default export-example.css file, and I assume that the lack of interaction in the result reflects the lack of coding for links in that file. This was tested with the 2014-08-27 standalone. \setupbackend[export=xmltest.xml,xhtml=xmltest.xhtml,css=export-example.css] \setupinteraction[state=start] \useURL[avecAmpersand] [http://www.mail-archive.com/search?l=ntg-context@ntg.nl&q=Epub] [][klik hier] \starttext \startsubject[title=Fails in xml] \startparagraph \tex{from}: \from[avecAmpersand] \stopparagraph \startparagraph \tex{goto&[url]}: \goto{klik hier}[url(http://www.mail-archive.com/search?l=ntg-context@ntg.nl&q=Epub)] \stopparagraph \stopsubject \startsubject[title=Okay in xml] \startparagraph \tex{url}: \url[avecAmpersand] \stopparagraph \startparagraph \tex{hyphenatedurl}: \hyphenatedurl{http://www.mail-archive.com/search?l=ntg-context@ntg.nl&q=Epub} \stopparagraph \stopsubject \stoptext -- Rik Kabel
