presence of xml-attribute
by H. van der Meer 08 Jun '10

08 Jun '10

In order to differentiate between the case of an absent or an empty attribute on an xml-element I now use the following macro to set a TeX- \if: % #1=node #2=attribute #3 defaultvalue: execute \attributetrue/false \def\setFlagToAttribute#1#2#3{% \doifnot{\xmlattdef{#1}{#2}{NOTPRESENT}}{NOTPRESENT}% {\doifelse{\xmlatt{#1}{#2}}{\empty}% {\xmlvalue{choice}{#3}{\iftrue}}% {\xmlvalue{choice}{\xmlatt{#1}{#2}}{\iftrue}}% \csname#2true\endcsname\else\csname#2false\endcsname\fi }% } I find the use of the NOTPRESENT not very elegant. Is there a path expression and function that can tell the presence or absence of an attribute, just as its value can be filtered with a/b[@option==value]? Hans van der Meer

xml path expression
by H. van der Meer 08 Jun '10

08 Jun '10

I would like to combine the xml path search of two different levels. An example, the xml can be either case #1: <main> <a> <b><c/></b> <b><c/></b> </a> </main> or case #2: <main> <b><c/></b> <b><c/></b> </main> Now I want to process the <c> elements from the <main> level and loop through them with the position function: \xmlfilter{#1}{/(a/b|b)/name/position(\the\scratchcounter)} This however does not work, I tried various path expressions, for example with * but to no avail. Is there a path expression that can select either /a/b or /b ? Hans van der Meer

\definetextbackground - problem with footnotes
by Alan BRASLAU 07 Jun '10

07 Jun '10

Hi, I use \definetextbackground to create an environment that is set-off from the main text. This (now) works correctly, except in the particular case when the backgrounded text wraps to a second page and the first page contains a footnote. In this particular case, the footnote also gets the background, which is not the desired behavior. Is this a bug or am I not using \definetextbackground correctly? Alan Minimal example (see also attached pdf): \definetextbackground [example] [location=paragraph, background=color,backgroundscreen=middlegray, leftoffset=0.5cm,rightoffset=0.5cm, topoffset=.25ex,bottomoffset=.25ex, before={\blank[small]\switchtobodyfont[script]}, after={\blank[small]}, frame=off] \starttext \input tufte\footnote{Do we ever get tired of this text?}\par \dorecurse{3} {\input tufte\par} \startexample \input knuth \stopexample \input tufte \stoptext

Clipping of text (or something equivalent)
by Erik Margraf 07 Jun '10

07 Jun '10

Hi all, I'd like to achieve in context something like I did in the attachment (context.pdf). My idea was (and that's the way how I did this in Inkscape): - Create Text - Double the text - Clip one for the upper half, clip the other for the lower half - Connect the two halves. My (probably naive) approach to clipping text in context was: ----- \starttext \startuniqueMPgraphic{context} draw btex \bf Context etex xyscaled (4.0, 4.0) withcolor .8white ; clip currentpicture to unitsquare; \stopuniqueMPgraphic \null\dontcomplain \uniqueMPgraphic{context} ----- (Without the "clip" - line, the string "Context" is displayed. With clipping, nothing is displayed.) Any hint in the right direction towards clipping or maybe a better way to achieve this is appreciated. Thanks Erik

referenceformat MkIV
by Yury G. Kudryashov 07 Jun '10

07 Jun '10

Hi! I try the following: \definereferenceformat[ineq][left=(,right=),text=Equation] \starttext \placeformula[first] \startformula 2=2 \stopformula In \in[first] ineq \ineq[first] in \in[first]. \stoptext The result is: 2 = 2 (1) In 1 ineq (1) in (1). It seems that \ineq doesn't clear some variables, and the next \in uses the previous format.

Script to automatically generate typescripts
by Michael Murphy 07 Jun '10

07 Jun '10

Hi all, after spending many hours on a typescript only to accidentally delete it, I thought that there should be a better way to write them. Hence I wrote a python script to do just that. It started out as a private project, but I thought that since it might be useful to others, I'd make it available publicly. You can get hold of it here: http://github.com/murphy-md/otftsmrk Note that it currently only works on Adobe .otf fonts (and this likely won't change), and that you need to be using LuaTeX with MkIV, since I don't do any of the encoding stuff. Please send me bug reports / feature requests if you use it! -- Michael Murphy

Cyrillic in Mark IV
by Yury G. Kudryashov 07 Jun '10

07 Jun '10

Hi! How can I typeset Russian in Mark IV? None of the examples from wiki work. I found "TeXGyre and (no) Cyrillic" thread, but there are no instructions, just "Cyrillic doesn't work with TeXGyre anymore".

You don't want Intruduction in the table of contents. Then just use > \subject{Introduction}. Thank you too! I do want Introduction to be in the contents! Maybe, its easier to setup \subject so that it will be included, then to invent new keywords? -- Best Regards, Vyatcheslav Yatskovsky
