Strange behavior of framed text
by Aditya Mahajan 21 Feb '08

21 Feb '08

Hi, In core-rul.tex we have %D We define the general (and original) case by just saying: \defineframedtext[\v!framedtext] This gives strange user behavior. Consider the following \defineframedtext[test][width=broad] \showframe \starttext \starttest \input tufte \stoptest \startframedtext[test] \input tufte \stopframedtext \stoptext The two framedtext have different widths. Why not say \def\startframedtext {\dosingleempty\dostartframedtext} \def\stopframedtext{\dostopframedtext} Aditya

Adobe Reader, PNG transparency and colors
by Michal Kvasnička 21 Feb '08

21 Feb '08

Hallo you all. I found a strange problem. I create my slides with ConTeXt. Everything was all right before I included pictures in PNG with transparent background. Adobe Reader 8.1.2 under Linux (at least this one) changes colors on every page where such a PNG is included. Xpdf shows it all right. I wonder what could be the reason, and how to solve it. Can you hint me? You can see the behavior here: http://www.econ.muni.cz/~qasar/vyuka/inst/inst-slide01.pdf Notice difference in colors between the 2nd and 3rd page (the 3rd one includes PNG). PNG are created with Gimp. My ConTeXt is ver: 2008.01.28 21:28 MKII pdfTeX is 3.141592-1.40.3 (Web2C 7.5.6) TeXExec is version 6.2.0 All under openSuSE Linux 10.3. When I start TeXExec, I got this warning: /usr/bin/texmfstart:1838: warning: Insecure world writable dir /home/qasar/bin in PATH, mode 040777 /usr/share/texmf/scripts/context/ruby/base/system.rb:16: warning: Insecure world writable dir /home/qasar/bin in PATH, mode 040777 But I guess it has nothing to do with the color problem. Many greetings to all of you, and thanks to those answering me. ;-) Have a nice day. M.K.

crash with \attributedbox

Hi, I updated my binaries today (minimals) and got some crashes using luatex v0.22. No probs with the prior version. I was able to make a minimal example by simplifying my original code.

As it stands, it seems safe to > say that, if colors don't work, then PGF is quite crippled in ConTeXt. No, the reason for the error is more subtle. PGF does try its best to work with ConTeXt colors. However, there is a difference between latex and context color usage, that gives rise to the error. The culprit in this case is: {$\displaystyle \tan \alpha \color{black}= \frac{{\color[red]\sin \alpha}}{{\color[blue]\cos \alpha}}$} Try this in a standalong context file (no pgf) and you will get an error. First you need to change \color{black} to \color[black]. Even then you will get an error. You need to use {$\displaystyle \tan \alpha {\color[black]= \frac{{\color[red]\sin \alpha}}{{\color[blue]\cos \alpha}}}$} (Notice the {...} around \color[black]). Then everything works fine. Here is a working example (latest pgf from cvs, but should also work with 1.18). \usemodule[tikz] \setupcolors[state=start] \starttext \starttikzpicture[scale=3] \clip (-2,-0.2) rectangle (2,0.8); \draw[step=.5cm,gray,very thin] (-1.4,-1.4) grid (1.4,1.4); \filldraw[fill=green!20,draw=green!50!black] (0,0) -- (3mm,0mm) arc (0:30:3mm) -- cycle; \draw[->] (-1.5,0) -- (1.5,0) coordinate (x axis); \draw[->] (0,-1.5) -- (0,1.5) coordinate (y axis); \draw (0,0) circle (1cm); \draw[very thick,red] (30:1cm) -- node[left=1pt,fill=white] {$\sin \alpha$} (30:1cm |- x axis); \draw[very thick,blue] (30:1cm |- x axis) -- node[below=2pt,fill=white] {$\cos \alpha$} (0,0); \draw[very thick,orange] (1,0) -- node [right=1pt,fill=white] {$\displaystyle \tan \alpha {\color[black]= \frac{{\color[red]\sin \alpha}}{{\color[blue]\cos \alpha}}}$} (intersection of 0,0--30:1cm and 1,0--1,1) coordinate (t); \draw (0,0) -- (t); \foreach \x/\xtext in {-1, -0.5/-\frac{1}{2}, 1} \draw (\x cm,1pt) -- (\x cm,-1pt) node[anchor=north,fill=white] {$\xtext$}; \foreach \y/\ytext in {-1, -0.5/-\frac{1}{2}, 0.5/\frac{1}{2}, 1} \draw (1pt,\y cm) -- (-1pt,\y cm) node[anchor=east,fill=white] {$\ytext$}; \stoptikzpicture \stoptext Aditya

Bug? Cross referencing and \setuparranging
by Jeff Smith 18 Feb '08

18 Feb '08

Hi, There seems to be a bug with the current ConTeXt (2008.01.28). When using \setuparranging (I've tried more than one setup), cross-referencing doesn't work. You get ?? instead of whatever number you should get. It happens to me with this simple dummy document: \setuppapersize[A5][A3] \setuparranging[2UP,doublesided] \starttext \chapter[chap1]{Chapter One} \dorecurse{4}{\input knuth \par} \chapter[chap2]{Chapter Two} \dorecurse{4}{\input knuth \par} \chapter[chap3]{Chapter Three} In chapter \in[chap1] of this document, there was something to read. \stoptext If you comment out the \setuparranging command, the \in command will work. If you don't, the log shows the following: chapter : 3 Chapter Three references : unknown reference [][chap1] This looks like a bug? Jeff

latest release doesn't "make"
by Henning Hraban Ramm 17 Feb '08

Ahoi, just tried to update via ctxtools, but making formats stops at Greek hyphenation patterns: (/usr/local/texlive/2007/../texmf-local/tex/context/patterns/lang- agr.pat ! Nonletter. l.234 ᾿ 2ρ1῾2ρ If I press "r" to continue I get a long list of more Greek "nonletters". Is that caused by the known LM change? Greetlings from Lake Constance!

trouble with indices
by Jesse Alama 17 Feb '08

17 Feb '08

I've noticed that with the most recent ConTeXt release I'm unable to make indices. This example fails: \starttext Hello, this \index{copula}is an index. \completeindex \stoptext The error I get is: chapter : 1 \headtext {index} ! Extra }, or forgotten \endgroup. \stoppacked ->\par \ifvmode \egroup \ifdim \lastskip =\noparskipsignal \rela... \doutilities ...protectutilities \unprotect \fi #4 \the \everybeforeutilityre... \doplaceregister ...ster \stoppacked \stopcolumns \endgroup \fi \docompleteregister ...ter [\currentregister ][#2] \page [\v!yes ]\endgroup \fi <to be read again> \par l.6 ? The error arises both with pdftex or xetex. I think that some recent change must be responsible for this, because I didn't notice any problems with indices, say, a couple months ago. What might be going on? Thanks, Jesse -- Jesse Alama (alama(a)stanford.edu)

setupreferenceformat questions
by Santy, Michael 17 Feb '08

17 Feb '08

Due to some fairly unique customer requirements for bibliography, we're using the simple bibliography discussed in the wiki (http://wiki.contextgarden.net/Simple_Bibliography) While this approach gives us more flexibility, I'm having trouble with a couple of things... 1) The code below wraps the reference number in brackets. How would I make the reference number superscript (like an endnote)? 2) The references in the text are numbered in the order the bibitems are defined in the bibliography, not the order on which they are cited in the text. How would I order them according to the order in which they occur in the text? Thanks, Mike Santy \setupinteraction[state=start] \definereferenceformat[cite][left={[},right={]}] \defineitemgroup [bibliography] [levels=1] \setupitemgroup [bibliography] [symbol=n, left={[}, right={]}, width=1.5em, stopper=, itemalign=flushright, inbetween={\blank[4pt]}] \appendtoks \let \bibitem \itemgroupitem \to \itemgroupcommands \starttext Now is the time\cite[ref2] for all good men\cite[ref1]. I would like the citations to be numbered based on the order in which they occur in the document, not in the bibliography. \section{References} \startbibliography \bibitem[ref1] This is my first reference \bibitem[ref2] This is the second reference \stopbibliography \stoptext
