Hello, I do not answer the question, but I'm interested because I also use Asymptote. The following code works with context in texlive 2016 but does not work with standalone context. thank you,

it probably depends on what you want to pass as info (i don't have asymptote installed nor time to check it) but if the code you pass gets expanded then you can add expandable macros or \the\foo kind of code to it Hans

Fabrice % macros=mkvi

\usemodule[filter]

\defineexternalfilter [ASY] [ filter={asy -tex "context" -outformat pdf -outname \externalfilteroutputfile}, output=\externalfilterbasefile.pdf, cache=yes, readcommand=\ReadImage, ]

\define[1]\ReadImage{\externalfigure[#1]}

\starttext Testing if we can include an asymptote image \startplacefigure[location={here}, title={An Asymptote figure}] \startASY import three; size(8cm,0); currentlight.background=black;

material White(real x, real y){ return material(diffusepen=gray(.05+.1x+.3y), emissivepen=gray(.05+.1x+.3y)); }

for(int y=0; y<=2; ++y) for(int x=0; x<3; ++x) draw(shift(2x,2y,0)*unitsphere,White(x,y)); \stopASY \stopplacefigure \stoptext

Hello ConTeXtist,____

I saw the opportunity to insert an Asymptote picture into Context source code (due filter).____

For example here: https://mailman.ntg.nl/pipermail/ntg-context/2015/080581.html https://mailman.ntg.nl/pipermail/ntg-context/2015/080581.html____

Is there a way to pass the ConTeXt parameter which influenced the creation of the Asymptote image? My point eg. the ability to define macros, which gave its parameters to Asymptote procedure or function and depending on these parameters, the image created by Asymptote looked differently.____

__ __

Before starting work on an illustrative example I am asking, whether it makes sense to deal with such a thing ... I suppose the impossibility of combining asymptote code and such Lua code (or not?).____

__ __

There is a similar possibility, at least in Metapost? For simpler pictures it would probably suffice ....____

Thanx ____
