overset in ConTeXt
by Jean Magnan de Bornier 19 Feb '07

19 Feb '07

Hi all, I cannot find how to type a bar over a letter in math mode; in LaTeX the command is something like \overset{-}{q}; but ConTeXt doesn't like it: ! Undefined control sequence. l.1869 p(q_1 + \overset {-}{q_2})+q_1 \frac{dp}{dQ} - Cm_1(q_1) = 0 ? X I have this: \usemodule[amsl] \usemodule[newmat] \usemodule[nath] doesn't seem enough, and I'm sure the solution is right there :-( tia -- Jean Magnan de Bornier | Cours Victor Hugo e-mots: jean at bornier.net | 13980 Alleins France T 09 50 39 34 03 | P 06 09 17 35 87

header on last missing when processing xml
by Ulf Martin 18 Feb '07

18 Feb '07

Hi Mighty ConTeXters! I have a problem: when I process the XML file 'headertest.xml' below, using 'headertest.tex' (below) with: texmfstart texexec --xtx headertest.tex I get four pages of output (as expected) but on the last page (page 4 in this case) the headline is missing (not expected). Why? And how can this be fixed (i.e. header on all pages)? I experienced this problem with other XML processing tasks, it is always the header on the last page that is missing (one can test this by changing the times parameter of the repeat tag in the XML file). Thank you & Cheers! Ulf Martin === XML === <?xml version="1.0" encoding="utf-8"?>  <document> <header text="Header Test Document" /> <repeat times="10"> <sectiontitle>Header Test section</sectiontitle> <knuth /> </repeat> </document>  === TeX === %% FILE(headertest.tex) \defineXMLargument [repeat] {\dorecurse{\XMLpar{repeat}{times}{}}} \defineXMLargument [sectiontitle] {\section} \defineXMLsingular [knuth] {\input knuth\par\ } \defineXMLsingular [header] {\setupheadertexts[\XMLpar{header}{text}{}]} \setuppagenumbering[location={footer,middle}] \starttext \processXMLfilegrouped {headertest.xml} \stoptext %% ENDFILE(headertest.tex)

So I have to be more careful with space. Thank you for clue. Zulkifli

replacing symbols
by Vyatcheslav Yatskovsky 17 Feb '07

17 Feb '07

Hi, Let me restate my question. If I get some text from an XML file using \XMLflush, is there a command in PLAIN TeX to replace some symbols (say, “&“ -> \letterampersand), on-a-fly without invoking perl, ruby, or lisp or ...? Why is there need in external script to do such an easy thing? And what I have to do to use Lua scripts, if possible? Cheers, Vyatcheslav

Newbie questions: integrating ruby/perl scripts into a document; changing line spacing for typed text only
by Vyatcheslav Yatskovsky 17 Feb '07

17 Feb '07

Hello, I want to ask a few questions that I cannot resolve by myself so far. 1) How can I integrate ruby/perl scripts into a .tex document? (I want to create a CD cataloguing tool and gonna use script for reading CD file list). 2) How to change line spacing for typed text only? (I use medium space for the whole document but want minimal spacing inside \starttyping)? With beat regards, Vyatcheslav Yatskovsky

Re: [NTG-context] vertical stretch for TABLE ?
by luigi scarso 16 Feb '07

16 Feb '07

Sorry, no news (but I re-discover \traceTABLEtrue...) Hint: look into cont-ntb.tex . There are some examples that aren't show even if you create the documentation with --modules switch.

Enabling PDF comments with ConTeXt
by Jan Mikkelsen 16 Feb '07

16 Feb '07

Hi, In early 2005 there was a thread "ConTeXt tool for enabling comments in PDF ?" which discussed the ways in which the output from ConTeXt/pdftex could be commented on by an Acrobat user using the PDF commenting feature. Has anyone done anything more on this? Is there some magic "--enable-commenting" switch that I can't see? Thanks, Jan Mikkelsen

CD cover tool -- handling unusual symbols in folder names
by Vyatcheslav Yatskovsky 16 Feb '07

16 Feb '07

Hello, I try to implement a script that will typeset covers for CD/DVD's that contain music compilations. Now I have script that follows. It scans the root directory of a CD for folders and outputs them a list. The major problem is that I have " & " and " ' " symbols in folder names on which script fails complaining (D:\context\xmldir-1.xml subject : - Music ! Argument of & has an extra }. <inserted text> \par <to be read again> } \next1 #1,->\dosetups {#1} \doprocesscommaitem \doprocesscommalist ...item \gobbleoneargument #1, ]\relax \global \advance \... \XML:ele:/file ->\setups [xmldir:file] \endgraf \egroup l.8 </file> ? !

\start-\stop footnotes
by Idris Samawi Hamid 16 Feb '07

16 Feb '07

Dear syndicate, For looong footnotes it would be nice to have \start-\stop footnotes for easier editing, but these are not defined in ConTeXt. So I tried ============================ \definestartstop [footnote] [before=\footnote\bgroup, after=\egroup] \startbuffer[footnote]% test test test test test test test test \footnote{This is a basic footnote.} test test test test test test test test \footnote{This is another basic footnote.} test test test test test test test test test test test test test. \startfootnote Here is a footnote environment. \stopfootnote \stopbuffer {\typebuffer[footnote] \getbuffer[footnote]} \page ============================ But this does nothing. [before=\footnote{, after=}] does not work either (and is not equivalent to (b/e}group). Please advise!
