Hi, Is it possible to put side by side text and a figure created in a TikZ environment ? Thank you, Fabrice \usemodule[tikz] \usetikzlibrary[calc] \starttext \def\smiley{% \starttikzpicture[baseline=-0.75ex,black] \filldraw[fill=orange] circle (2mm); \node[fill,circle,inner sep=0.5pt] (left eye) at (135:0.8mm) {}; \node[fill,circle,inner sep=0.5pt] (right eye) at (45:0.8mm) {}; \draw (-145:0.9mm) arc (-120:-60:1.5mm); \stoptikzpicture} \placefigure[right,none]{}{ \starttikzpicture \coordinate (c1) at (0,0); \draw[thick,fill=darkgreen] ($(c1) + (0:30mm)$) arc (0:360:30mm) ($(c1) + (360:35mm)$) arc (360:0:35mm); \draw[thick,fill=gray] ($(c1) + (0:3mm)$) arc (0:360:3mm); \foreach \x in {0,36,...,180} \draw[fill=red, draw=black](c1)--(\x:30mm) arc (\x:\x+36:30mm)--(c1); \foreach \x in {216,252,...,324} \draw[fill=blue, draw=black](c1)--(\x:30mm) arc (\x:\x+36:30mm)--(c1); \foreach \x in {3,12,...,360} \draw[fill=lightgray] (\x:28mm) circle (2pt); \draw[thick,fill=white!30] ($(c1) + (0:3mm)$) arc (0:360:3mm) ($(c1) + (360:4mm)$) arc (360:0:4mm); \draw[thick,fill=darkgray] ($(c1) + (0:3mm)$) arc (0:360:3mm); \foreach \x in {18,54,...,198} \node [white,rotate=\x] at (\x:17.5mm){\small \bf PERDU}; \foreach \x in {234,270,306,342} \node [] at (\x:17.5mm) {\smiley}; \draw[darkgray,-latex,line width=4pt, line cap=round] (90:37mm) -- (90:26mm); \stoptikzpicture} \input knuth \stoptext

Line number in "tex error"
by Mikael P. Sundqvist 25 Apr '14

25 Apr '14

Hi, When running the five lines long file \starttext Bla bla \blank[foo] Bla bla \stoptext through context I get the error below (the foo in the blank is there to get an error, see the attached log file for the full log file). My question is why is context first telling me that the error is on line 8 and not 3? (In this particular example this is not a problem, but I'd like to grep for errors in the log file when running through the editor). I see that the error is later said to be at line 3... /Mikael ====== STARTERROR ====== tex error > error on line 8 in file /home/mickep/tmp/err.tex: ! Missing number, treated as zero <to be read again> f <argument> f oo \addaskedblankskip ..._vspacing_temp #1\dimexpr #2 \relax l.8 } \ctxcommand #12-\directlua {commands.#1} \spac_vspacing_yes_indeed ...mand {vspacing("#1")} \fi l.3 \blank[foo] 1 \starttext 2 Bla bla 3 \blank[foo] 4 Bla bla 5 \stoptext 6 ? ====== STOPERROR ======

Dear all, The following example doesn't work for me: \setupbodyfont[xits] \starttext \math{x\mathextensible{"2194}{hello}{}y} \math{x\mathextensible{"21FE}{hello}{}y} \math{\char"21FE} \stoptext I found the symbol which I needed there: http://en.wikipedia.org/wiki/Arrow_%28symbol%29#Arrows_in_Unicode and there: http://milde.users.sourceforge.net/LUCR/Math/unimathcmds.pdf Kind regards, Chris

https://stripe.com/blog/stripe-open-source-retreat Grant of $7500 per month, plus food, for working on OSS projects. If there's something that could use three months of F/T work that would be massively helpful for ConTeXt, it might be worthwhile submitting a proposal.

textcolor not working with MPinstance
by Aditya Mahajan 24 Apr '14

24 Apr '14

Hi, textcolor does not work any longer with MPinstance. Consider the following example from the wiki: http://wiki.contextgarden.net/Command/defineMPinstance \defineMPinstance [important] [metafun] % needs to be inherited from the global metafun instance [textcolor=red] \defineMPinstance [veryimportant] [important] [textstyle=bold] \starttext % normal black text \startMPcode draw textext("some text") ; \stopMPcode % red text \startMPcode{important} draw textext("some text") ; \stopMPcode % red bold text \startMPcode{veryimportant} draw textext("some text") ; \stopMPcode % a graphic that uses a custom instance % This does not work with the current stable version \startuseMPgraphic{veryimportant::mygraphic} draw textext("some text") ; \stopuseMPgraphic \useMPgraphic{veryimportant::mygraphic} \stoptext Thanks, Aditya

Attributes
by Stéphane Goujet 24 Apr '14

24 Apr '14

Hello, I would like to know what is the recommended way to use attributes in Context. I manage to use use them with numbers, i.e. : in Context : \attribute123=1 in Lua : has_attribute(my_node, 123) But I would like to make that cleaner and use named attributes. What is the Context way to declare and set attributes? Is it something like this? \defineattribute[myattr] \dosetattribute{myattr}{1} And how do I then access them from Lua? Should it look like has_attribute(mynode, attributes.myattr) or has_attribute(mynode, attributes.xxxxx("myattr")) or something else? Goodbye, Stéphane.

\setupmathradical[sqrt] crunches denominator in an \over fraction
by Sanjoy Mahajan 24 Apr '14

24 Apr '14

I have been trying out the newish \setupmathradical[sqrt][alternative=mp], which has been very nice because of the fine control over the radical sign. I've noticed that it crunches the denominator in \sqrt{a\over b} For example: \starttext \placeformula\startformula \sqrt{k\over m}\quad \sqrt{\displaystyle{k\over m}} \stopformula \setupmathradical[sqrt][alternative=mp] \placeformula\startformula \sqrt{k\over m}\quad \sqrt{\displaystyle{k\over m}} \stopformula \stoptext In the first line, the fractions come out fine. In the second line, the first k\over m has a small, inline-math m in the denominator but a display-math k in the numerator. The second sqrt is fine. Is the problem that my plain-TeX habits, from decades using \over, should be over, and that \frac is the recommended way? (This is with the 2014.03.27 beta.) -Sanjoy
