header/footertexts (sectioning)
by Alan BRASLAU 08 Jun '10

08 Jun '10

Hello, I am using: \setupfootertexts [chapter] \setupheadertexts [section] \setupheadertexts [][pagenumber] [pagenumber][] % doublesided to place the chapter title in the footer and the section title in the header. (Of course, I also use \setuphead [chapter] [header=nomarking,footer=empty,page=right] \setuphead [part] [header=nomarking,footer=empty,page=right] so that \chapter{} and \part{} begin on an odd page without a text header nor a footer.) However, a \chapter{} may begin with a long introduction (several pages) before seeing a \section{}. In this case, the header gets the title of the last section of the preceeding chapter. Similarly, a \part{} may begin with a long introduction (several pages) before seeing a \chapter{}. In this case, the footer gets the title of the last chapter of the preceeding part. This is incorrect. Is there some way to have the section text reset for each \chapter and the chapter text reset for each \part? (I would expect a "way=bychapter" and "way=bypart" type of option and also suggest that this be the default behavior). Alan By the way, there appears to be a (recent) bug in that \setupheadertexts [section] \setupheadertexts [][pagenumber] [pagenumber][] % doublesided works, whereas \setupheadertexts [][pagenumber] [pagenumber][] % doublesided \setupheadertexts [section] currently is broken (no page numbers occur).

Problems using new beta
by Ivo Solnický 08 Jun '10

08 Jun '10

Hi all! I am just new to ConTeXt, I have played with it for one week. I have installed standard ConTeXt minimals installation and no other TeX distro is installed on my MS Vista computer. I use also TeXworks editor. On Sunday, after I installed new package, I realized, that my workflow is broken. I received next message in my TeXworks editor, the same for command line: MTXrun | run 1: luatex --fmt="C:/context/tex/texmf-cache/luatex-cache/context/2fea56f92e5267d7cc9662e4d5f52e1e/formats/cont-en" --lua="C:/context/tex/texmf-cache/luatex-cache/context/2fea56f92e5267d7cc9662e4d5f52e1e/formats/cont-en.lui" --backend=pdf "./dopis.tex" This is LuaTeX, Version beta-0.60.1-2010060523 (Web2C 2010) (rev 3685) \write18 enabled. ! I can't find file `./dopis.tex'. <*> ./dopis.tex Please type another input file name: I have my documents in "C:\Users\Ivo\TeX" directory and ConTeXt worked fine until the new sync. When I tried to find what is wrong, I realized strange thing. When I move my document somewhere inside my TEXMF tree (C:\context\tex), it works. For example I copied dopis.tex into c:\context\tex\texmf-project and everything was ok. Maybe it is my mistake, but I am not experienced enough to find it. But it worked before. Maybe this is related to another problem I have. When I compile ConTeXt documents from my user directory, MTXrun said: MTXrun | warning: source mismatch (luv: 768743af5acbbfb6f306763f3da964ca <> bin: a6c26bf5f4881a58ccc3eed80ae65790), forcing remake MTXrun | fileio: loading configuration file 'C:/context/tex/texmf/web2c/texmfcnf.lua' MTXrun | fileio: loading configuration file C:/context/tex/texmf/web2c/texmf.cnf MTXrun | fileio: preparing 'configuration' for 'C:/context/tex/texmf/web2c' MTXrun | fileio: 'configuration' saved in 'C:/context/tex/texmf-cache/luatex-cache/context/2fea56f92e5267d7cc9662e4d5f52e1e/trees/53ad5f8b88994bdd02baa17501789699.lua' MTXrun | fileio: 'configuration' compiled to 'C:/context/tex/texmf-cache/luatex-cache/context/2fea56f92e5267d7cc9662e4d5f52e1e/trees/53ad5f8b88994bdd02baa17501789699.luc' MTXrun | fileio: locating list of '/texmf' .... and recompiled format every time I run Context. This is very time consuming. But this is not true when I compile documents inside my TEXMF tree, for example in c:\context\tex\texmf-project directory. Any help? I still have some questions about the ConTeXt itself, but first I would like to solve these problems. If you need any additional information I am ready to send it. Thanks. Ivo Solnicky

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
