Hello, In http://wiki.contextgarden.net/Bibliography_mkiv, it's little talked about bibliography support on MKIV. Does yet exist a documentation about how to use it? -- Wagner Macedo

Command \thanks from LaTeX
by Wagner Macedo 21 Jan '12

21 Jan '12

Hello, Searching for a \thanks equivalent command on ConTeXt, I ended up on http://wiki.contextgarden.net/LaTeX_Thanks. But I didn't like that solution, because the author footnote is placed on a new area instead the same as text footnotes. So I made a simple solution, that the author footnotes is placed in the same area and doesn't interfere on real counter. I want here to share my solution, below you can see it. \definestartstop[author] [before={\savenumber[footnote] \resetnumber[footnote] \start \let\thanks\footnote \setupfootnotes[numberconversion=set 2]}, after={\stop \restorenumber[footnote]}] It can be used as that: \startauthor Wagner Macedo\thanks{Brazilian citizen} \stopauthor Of course, I could did a \author command, but I generally prefer to use start/stop blocks. What do you think? This could be improved?

But why should there be any implicit DPI specified with a vector graphic?

checking attributes
by Meer, H. van der 20 Jan '12

20 Jan '12

Is the following impossible? The aim is checking the value of an attribute on a node: \xmlfilter{#1}{/content[@type ==\whatever]/command(xmlcommon:content)} It seems the \whatever macro is not expanded. How to? Hans van der Meer

endnotes, imposition and recurselevel
by Michael Guravage 20 Jan '12

20 Jan '12

I am typesetting an article where the footnotes should be collected as endnotes. I am also using imposition to arrange the article as a booklet. When using the default location 'page', footnotes work as expected. But when I change the location to 'text' and use \placefootnotes to produce the endnotes, the compilation fails. Here is an example document that attempts the same thing. Note that the paragraph/footnote loop is performed nine times. If you compile as is, i.e., no imposition, everything works as expected. But add --mode=imposition to apply imposition and the compilation fails. Now decrease the number of iterations from nine to eight and the behaviour is reversed. The imposition will succeed and the straight compile will fail. Stranger yet, If you remove the subject structure, compiling with eight iterations succeeds with or without imposition, and compiling with nine iterations fails with or without imposition. This all happens in the ConTeXt from 2011.07.26. Switching to the ConTeXt from 2012.01.16 everything compiles, but the runs using imposition produce only blank pages. Regardless of what I try, I cannot get endnotes and imposition to cooperate. Any help would be greatly appreciated. \showframe \doifmode{imposition} {\setuppapersize[A5,portrait][A4,landscape] \setuparranging[2UP,doublesided]} \setupfootnotes[location={text,none}] \starttext \startsubject[title=First] \dorecurse{9}{\input tufte\footnote{The quick brown fox jumps over the lazy dog.}\par} \stopsubject \startsubject[title=Second] \placefootnotes \stopsubject \stoptext -- With kind regards, Michael Guravage

include file in xml processing
by Hans van der Meer 20 Jan '12

20 Jan '12

I have the following setup for use of ConTeXt code in an xml-processing setup: % Usage: <tex> ... </tex> \startxmlsetups xmlcommon:tex \ignorespaces \xmlstripnolines{#1}{.} % need to strip sufficient space characters \xmlcontext{#1}{.} \stopxmlsetups Since I need some MetaPost drawings repeatedly I thought to include those from a separate file: <tex> \input thedirectory/thefile \useMPgraphic{lfsr}{stages=285} </tex> The file is read, but typeset as is, MetaPost processing does not occur. By the way, inserting the MetaPost code in place of the \input works ok. I also tried \usemodule[thedirectory/thefile] instead, but then nearly everything MetaPost encounters is undefined. Does someone know how to get the file inclusion right? Hans van der Meer

typesetting verbatim code snippets in xml mkiv
by Michael Guravage 20 Jan '12

20 Jan '12

In attempting to use Thomas's xml presentation style he presented at C5M, I would like to add the ability to typeset verbatim code snippets. In the xml:code setup example below, using commands like \startlinenumbering-\stoplinenumbering work fine, but using \starttyping-\stoptyping breaks. Can someone please enlighten me as to the correct way to accomplish this sort of thing? \startxmlsetups xml:codesetups \xmlsetsetup{#1}{*}{-} \xmlsetsetup{#1}{document|code}{xml:*} \stopxmlsetups \xmlregistersetup{xml:codesetups} % document \startxmlsetups xml:document \xmlflush{#1} \stopxmlsetups % xml code \startxmlsetups xml:code \starttyping \xmlflush{#1} \stoptyping \stopxmlsetups <?xml version="1.0" encoding="UTF-8" standalone="yes"?> <document> <code> int x; x = 42; </code> </document> -- With kind regards, Michael Guravage

≙ is not shown correctly
by Xenia 20 Jan '12

20 Jan '12

Dear context-folks, the unicode-character ≙ is not shown in the normal text-mode and in math-mode the hat is too big in comparison to `\mathrel{\widehat{=}}`. Is that a font problem? Thanks, Xenia
