No! On page 3 there should be a difference between figure 1/2 and figure 2/3, if I understand it right. But there is nothing. page-flt.tex is changed at 2006.09.24 There is also a file core-pos.tex and core-pos.mkii from 2006.09.24 both. > Wolfgang (the younger one?) passports are not allways up-to-date! :-) Wolfgang

## in \def in \sometxt fails with static MP figure
by Sanjoy Mahajan 30 Sep '06

30 Sep '06

Now that \sometxt works with static figures (thanks!), I'm converting from using btex..etex to using \sometxt, to avoid MPenvironments (instead put it in the general .tex environment). But I ran into an error with macro arguments and static figures. Let me know if it's not worth fixing in view of the Mk IV cleanup, and I'll switch to reusable figures (and eventually Linux will support dual core CPUs + suspend to ram, and then I won't notice the processing time much). Here is a small example file: ================= y.tex ======================== \def\2#1#2{\vbox{\halign{##\hfil\cr#1\cr#2\cr}}} \starttext \startstaticMPfigure{fig} label(\sometxt{\2{h}{x}}, origin); \stopstaticMPfigure \usestaticMPfigure[fig] \stoptext ================= y.tex ======================== It produces this texexec.tex (2006.09.28 22:43 beta): ================ texexec.tex ===================== \setupoutput[pdftex] \setupcolors[state=start] \global \loadfontfileoncetrue \starttext \startMPpage beginfig(1); label(\sometxt{\vbox {\halign {##\hfil \cr h\cr x\cr }}}, origin); endfig; \stopMPpage \stoptext ================ texexec.tex ===================== The ## in the expanded argument to \sometxt causes a problem: =================== texexec.log ============== ! Only one # is allowed per tab. l.1 \vbox {\halign {## \hfil \cr h\cr x\cr }} \doTeXtext ... \startcurrentcolor \scantokens {#3} \stopcurrentcolor }\global... \dodofiltersometxt ...er \TeXtext \txtcounter {#1} \expandafter \filtersometx... <argument> ...halign {##\hfil \cr h\cr x\cr }}}, o rigin); endfig; \flushTeXtexts ...llectedmptexts \filtersometxt #1 \sometxt {}\empty \relax \... \writecheckedMPgraphic ...phic \flushTeXtexts {#1} \writeMPgraphic {#1} ... l.9 endfig; \stopMPpage ? =================== texexec.log ============== Alas using \def\2#1#2{\vbox{\halign{#\hfil\cr#1\cr#2\cr}}} leads to a different error (illegal parameter number). But using a reusable graphic works: ==================== yy.tex ===================== \def\2#1#2{\vbox{\halign{##\hfil\cr#1\cr#2\cr}}} \starttext \startreusableMPgraphic{fig} label(\sometxt{\2{h}{x}}, origin); \stopreusableMPgraphic \reuseMPgraphic{fig} \stoptext ==================== yy.tex ===================== -Sanjoy `A society of sheep must in time beget a government of wolves.' -- Bertrand de Jouvenal

btex..etex fails in reusableMPgraphic (2006.09.28 beta)
by Sanjoy Mahajan 30 Sep '06

30 Sep '06

Unless I'm doing something very silly, the following should and I am almost certain did work, but it fails with the 2006.09.28 beta: ================ btex.tex =================== \starttext \startreusableMPgraphic{fig} label(btex in b/e tex etex, origin); \stopreusableMPgraphic outside btex..etex\quad \reuseMPgraphic{fig} \stoptext ============================================ The output says systems : begin file btex-mpgraph-temp at line 42 ! Missing $ inserted. <inserted text> $ <to be read again> _ l.48 _ special_div_ := 10000; ? Here's a snippet from btex-mpgraph-temp.tex: \starttext \startMPXpage " mpgraph:=1; randomseed:=33; _special_div_ := 10000; The underscores in the variable name are upsetting to tex. I haven't tracked down the chain of influence that put them there. Meanwhile the same btex..etex test on a static MP figure works fine: ==================== btex-static.tex ================ \starttext \startstaticMPfigure{fig} label(btex in b/e tex etex, origin); \stopstaticMPfigure outside btex..etex\quad \usestaticMPfigure[fig] \stoptext ==================================================== -Sanjoy `A society of sheep must in time beget a government of wolves.' -- Bertrand de Jouvenal

run a ruby script and use the standard output ???
by Renaud AUBIN 30 Sep '06

30 Sep '06

Hi all, Is it possible to run a ruby script from a context document during its processing (I already know how to do that using \write18 but there is maybe a better way...) then get the output of the script to display or use it into the document. It's a little bit hard to describe so I have a simple example: \starttext \def\vartest{3.124325234543523452435} \write18{ruby ./myscript.rb \vartest XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX} \stoptext with myscript.rb: temp = ARGV[0] puts "\nXXXXXXXXXXXXX " + (Math::sqrt(temp.to_f)).to_s + " XXXXXXXXXXXXX\n" I would store the result of puts into a variable usable within ConTeXt...

3D Artwork with ConTeXt
by Renaud AUBIN 29 Sep '06

29 Sep '06

Hi all, I'm now playing with u3d and since I'm at rookie level in ConTeXt dev, I have (a lot?) of questions for you. First, download http://www.nibua-r.org/ConTeXt/devel/3dartwork.tgz and "texexec test-3dartwork". Since I use \externalfigure and u3d mean nothing to ConTeXt, I obtain TeXUtil | running texmfstart rlxtools --identify ./context.u3d identify: no decode delegate for this image format `./context.u3d'. RlxTools | unable to identify ./context.u3d Ok, this is normal... I used \placefigure and \externalfigure for convenience for the moment since I found natural to use them... How to bypass RlxTools ? Now, see t-3dartwork. There is a lot of work. The main idea is to split \doPDFinsertiiidartwork into several macros ;) . I need help on: 1. What's the best way to define the following macro \defineiiidartworkprojection[name][type=perspective|orthographic , nf=automatic|explicit , near=number, far=number, fov=number.....] You're welcome to give your opinion on naming convention ;) 2. Same question for \defineiiidartworkview[name][bgr=number, bgg=number, bgb=number (or 3 floats for bgcol), projection=name, camera= 3 floats (but how?), target= idem, up=idem] I'll use ruby and a magic | (see [NTG-context] run a ruby script and use the standard output ???) to calculate C2W and CO... 3. ... I need to define a macro to setup the 3D annot before to use it by \externalfigure or with another brand new macro... That's it for the moment... Renaud

transparent metafun colors turn nearly black
by Sanjoy Mahajan 29 Sep '06

29 Sep '06

Just for (meta)fun, I tried a few experiments with transparent colors. The example below gives a black circle instead of a red one. Is it that transparent colors aren't part of metafun -- which I can easily live with since color printing is too expensive still, alas -- or have I omitted an essential command? ==================== cut here ==================== \runMPgraphicstrue \setupcolors[state=start] \starttext \startreusableMPgraphic{a} % _inline_specials_ := true; % had hopes for this line, but no luck % next line taken as an example from mp-spec.mp fill fullcircle scaled 10cm withcolor transparent(8,.3,red); \stopreusableMPgraphic \placefigure[force,none]{}{\reuseMPgraphic{a}} \stoptext ==================== cut here ==================== The metapost output (testfile-mpgraph.1) always contains the following color setting, no matter what arguments I pass to transparent() : 0.123 0.003 0.001 setrgbcolor Which is close to black. (This is all with ConTeXt 2006.08.08. The live ConTeXt gives a square saying "undefined".) -Sanjoy `A society of sheep must in time beget a government of wolves.' -- Bertrand de Jouvenal

The other day I was just searching for Context books on Amazon and all over the web. I have bought 5 LaTeX books a few years ago and I was expecting to find some Context books. Also, some of the Context manuals are still unfinished. Specially the ones about style and layout. I liked those manuals very much, but too bad they are incomplete. I was looking for some book about that. Fidel.

MPenvironment ignored for btex..etex (or should I use sometxt)?
by Sanjoy Mahajan 29 Sep '06

29 Sep '06

I'm not sure what's going on here, but this file fails (2006.09.28 beta): [well I have a better idea now after writing out the whole email, see the end...] =================== 3.tex ================= \starttext \startMPenvironment \def\2{hello} \stopMPenvironment \startreusableMPgraphic{fig} label(btex \2 etex, origin); \stopreusableMPgraphic \reuseMPgraphic{fig} \stoptext ========================================= The error is (from 3.log): ============== error snippet =============== systems : begin file 3 at line 1 color : currentcolor (def) is not defined \openout7 = `3-mpgraph.mp'. !

So am I supposed to use the global option to \startMPenvironment? If it's needed in this case, I think it would be needed in every case (ConTeXt would see all the metapost uses of the definition). Or is btex deprecated and I should use \sometxt (except in loops)? Or am I just confused?! -Sanjoy `A society of sheep must in time beget a government of wolves.' -- Bertrand de Jouvenal

Texts after typing environment
by Zhichu Chen 29 Sep '06

29 Sep '06

Hello everybody, If I type: ------------------------------------------- \starttyping some verbatim texts \stoptyping -------------------------------------------- does ConTeXt treat it as a complete paragraph? In LaTeX, when I type: -------------------------------------- \begin{verbatim} some texts here \end{verbatim} some other texts \begin{verbatim} some texts here \end{verbatim} other materials --------------------------------------- The output will be --------------------------------------- some texts here some other texts some texts here other meterials -----> This line is indented !! ---------------------------------------- What should I do in ConTeXt? I really want to control this. but whether I leave a blank line after \stoptyping or not, nothing changed. Have I expressed my problem clearly? yours, chen
