Hello, I have a "conversion" defined in the following way: \usesymbols[jmn] \defineconversion [gnuplot] [$\bullet$, $\circ$, $\star$, x, {\symbol[navigation 1][NextJump]}] I would like to use these symbols in a macro draw_symbol(x,y,number) so that draw_symbol(0,0,3) would draw a star in the origin. The problem is that I don't know: - how to use symbol sets inside MetaFun (verbatimtex \usesymbols[jmn] etex doesn't work here) - how to enable label(btex \convertnumber{gnuplot}{5} etex, (x,y)) to work properly in metafun (no luck with verbatimtex ... etex again) Any hints would be appreciated. Thanks, Mojca

I am very much a beginner at metafun, so the following is probably garbage, but to its defence I can say that it actually achieves the goal :) There are two files: % myenv.tex: contains the symbol definition \usesymbols[jmn] \defineconversion [gnuplot] [$\bullet$, $\circ$, $\star$, x, {\symbol[navigation 1][NextJump]}] % end % sym.tex: the main file \environment myenv \startMPinclusions def draw_symbol(expr X, Y, Number) = label(textext(char 92 & "input myenv " & char 92 & "convertnumber{gnuplot}{" & decimal Number & "}"),(X,Y)) enddef \stopMPinclusions \starttext \startuseMPgraphic draw_symbol(0,0,3); \stopuseMPgraphic \useMPgraphic \stoptext % end I could not figure out how to use a 'verbatimtex' preamble either, so this loads the myenv definition file for each label. Ugly, but the best I can manage with my current knowledge. Cheers, Taco

ha, we reached similar solutions -) the solution for the inclusion is in \startMPenvironment \stopMPenvironment when this becomes a module, one can best append the code loading to \everyMPTEXgraphic as in \appendtoks \usemodule[...]% \to \everyMPTEXgraphic so that it will not clash with user defined environments and/or inclusions Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | fax: 038 477 53 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------

Thank you very much to both of you! This works perfectly and just the way I wanted. I have some other questions, but I have to write exact specification(s) first. (The whole documentation for implementing 3D features is approximately "read the cryptic implementation in PostScript, figure out what it does and implement it that way in your terminal". I hate that, but I'll try to come through it. I'll report as soon as there will be something functional available.) Thanks a lot for all the help, Mojca On 2/13/06, Hans Hagen wrote:
