\framed[backgroundcolor=x] might imply \framed[background=color]
by Johan Sandblom 02 Sep '08

02 Sep '08

What would be the drawback of allowing backgroundcolor=n imply background=color and backgroundscreen=x imply background=screen in the setup to \framed. Background compatibility should not be an issue and I am failing to imagine cases where it would not be desirable.

images as background
by Thomas A. Schmitz 02 Sep '08

02 Sep '08

Hi all, for a presentation, I would like to have a series of images as backgrounds for my slides, and I want to use them in a randomized order. The images are named "1.jpg" through "20.jpg." So I was thinking of using this code: \externalfigure[\directlua0{print(math.random(20))}][width=\paperwidth] epecting that this should But that doesn't work, ConTeXt doesn't find my pictures (I get "name: dummy" texts). Any idea what is going wrong? Thomas

Perfect. Thank you! Michael

bug with numeral conversion function
by Khaled Hosny 02 Sep '08

02 Sep '08

It seems that there is a bug in converters.alphabetic function, converters.alphabetic(0,"arabic") returns the western 0 (no matter what is the selected language) while converters.alphabetic(1,"arabic") gives the Arabic 0 not 1 and so one i.e. it looks like as if it starts counting from zero. This has been reported few weeks ago, but I think it got missed. Regards, Khaled -- Khaled Hosny Arabic localizer and member of Arabeyes.org team

"Float within a frame" challenge
by B. Tommy Jensen 02 Sep '08

02 Sep '08

Hi, I am trying to accomplish the following layout with ConTeXt: - An icon and a descriptive text should be contained together in a separate frame - The frame should be centered and have a special background color - Within the frame, the icon should be placed to the upper left. - A descriptive text should "flow" around the icon within the frame, first part to the right and then below the icon. I have tried the following construct: %---------------------- \startframedtext \placefigure[left]{none}{\externalfigure[danger]} The textual description of the icon comes here. It should ideally flow to the right of the figure within the frame, but the figure actually becomes behind the text. \stopframedtext %---------------------- The problem here is that the icon and text is placed on top of each other. When removing the frame (\startframedtext command), the placement of the figure and the text works OK, but I don't get a frame then of course. I have studied the "It's in the details" document which explains a great deal about float's, but I haven't found anything covering the frame issue. Is the "startframedtext" the wrong command to use? All hints or suggestions (like references to other tutorials) are very welcome. Best regards, Tommy Jensen

How does MPinclusions work in mkiv?
by Mojca Miklavec 02 Sep '08

02 Sep '08

Hello (Hans), this "minimal" example worked OK in mkiv back in May (most of settings in the code below are just unimportant cosmetics, but otherwise it's difficult to explain the idea behind); now it still works in mkii, but not in mkiv. \def\mynextmpgraphic{\startMPinclusions erase_picture := 1; \stopMPinclusions} \startusableMPgraphic{bubble} if erase_picture = 0: draw last_picture; else: % draw a new picture; in mkiv this code is only reached once, % \mynextgraphic does not reset erase_picture fi; \stopusableMPgraphic The code is ugly anyway, I know, but how should I reset variables to redraw the picture once more?

Installing ConTeXt Minimals on a Mac ... and using bibtex
by Michael Green 02 Sep '08

02 Sep '08

I have the minimals installed in ~/Applications/context/ Context works great. However, I'm having trouble with bibtex. [1] I export the following variables before using context. . ~/Applications/context/tex/setuptex ~/Applications/context/tex export TEXMFHOME='$HOME/Library/texmf' export TEXMF='{$TEXMFHOME,!!$TEXMFPROJECT,!!$TEXMFFONTS,!! $TEXMFLOCAL,!!$TEXMFCONTEXT,!!$TEXMFEXTRA,!!$TEXMFMAIN}'; (I added export PATH=/Applications/ConTeXtMinimals/tex/texmf-osx-intel/ bin:$PATH but that didn't seem to make a difference in a couple of quick trials) [2] The problem is that the minimal's bibtex can't find the bib file that I have stored in ~/Library/texmf/bibtex/bib/ It reports: "I couldn't open database file bib-name.bib" and "I found no database files---while reading file file-name.aux" [3] "which bibtex" yields the path to the bibtex installed with the minimals: /path-to-my-user-account/Applications/context/tex/texmf-osx-intel/bin/ bibtex [4] When I open a new shell session, "which bibtex" points to /usr/ texbin/bibtex. In this new shell, bibtex finds the bib file. It's a small thing, but if there's some other setting to make bibtex work in the same shell session that context does, that would be nice. Thanks!

cont-de help for context with MK IV
by Martin Scholz 02 Sep '08

02 Sep '08

Hi for all of you who want to compile documents with context under MK IV you can use luatools --make --compile cont-xx to compile your language, hereby you must replace xx by the country-code of your desired language and with luatools --run cont-xx myfile you can compile your document. If you are using the chemic-modul you should add the following to your preamble to let it compile correctly: \unprotect \def\MPdivten[#1]% {\@EA\@EA\@EA\doMPdivten\@EA\@EA\@EA[\@EA#1]} \def\doMPdivten[#1]% {\ifnum#1> 9999 \dodoMPdivtenB#1\else \ifnum#1> 999 \dodoMPdivtenC#1\else \ifnum#1> 99 \dodoMPdivtenD#1\else \ifnum#1> 9 \dodoMPdivtenE#1\else \ifnum#1> 0 \dodoMPdivtenF#1\else \ifnum#1<-9999 \dodoMPdivtenA#1\else \ifnum#1< -999 \dodoMPdivtenB#1\else \ifnum#1< -99 \dodoMPdivtenC#1\else \ifnum#1< -9 \dodoMPdivtenD#1\else \ifnum#1< 0 \dodoMPdivtenE#1\else 0 \fi\fi\fi\fi\fi\fi\fi\fi\fi\fi} \def\dodoMPdivtenA#1#2#3#4#5#6{#1#2#3#4#5.#6} \def\dodoMPdivtenB #1#2#3#4#5{#1#2#3#4.#5} \def\dodoMPdivtenC #1#2#3#4{#1#2#3.#4} \def\dodoMPdivtenD #1#2#3{#1#2.#3} \def\dodoMPdivtenE #1#2{#1.#2} \def\dodoMPdivtenF #1{.#1} \protect Thanks here to Wolfgang Schuster you just helped to figure out this howto. The question is now how could one give the language-option over to context by the context command or by edit the sourcefile with a command so that the command has the following input: context myfile with the language-option in a context-command in the source-file or like context --lang=de myfile where the --lang option refers to the above luatools option so that default luatools --run cont-en myfile is invoken and if --lang=xx is set the command is invoken in the following way luatools --run cont-xx myfile. Would be nice if one of the programmers could just implement the following option in MK IV. Greetings Martin

Color in math in MkIV
by Aditya Mahajan 02 Sep '08

02 Sep '08

Hi, The color commands do not work inside math mode in MKIV. For example $f(\color[blue]{A}) = b$ $f({\blue A}) = b$ come out black and $f(\blue{A}) = b$ colors everything blue. I have an easy work around for the moment: \unprotected\def\mathcolor[#1]#2% {\preparebinrel{#2} \currentbinrel{\text{\color[#1]$\m@th #2$}}} and then use \mathcolor. Aditya
