Could anybody explain how to use Asymptote in ConTeXt with the filter
module.

Thanks

Can you post a minimal asymptote file and how it shoud be processed via 
the command line?

I have no time to create a nice minimal example, but here's an ugly
non-minimal example which should at least enable you to test the
interaction with the filter module.

I also added one ConTeXt-specific command while trying to make math
fonts work properly, just replace "lucidaot" with another font in case
you don't have that one installed.

You can run the example with
    asy -tex context cylinder.asy

(Maybe it's possible to set the tex engine inside the file as well.)


Bonus points if you can get PRC to work properly before TL 2015. Or if
you can make the file print properly from OS X without using Acrobat
or ghostscript/CUPS. Preview.app "forgets" to print the (smoothly
shaded) cylinder for example.

Sorry, but I fail to see what the 3D aspect of this drawing brings to
anything, other than to impress the gallery and look spiffy.

I guess that we belong now to a society without any imagination,
requiring lots of colors, shadowing (and even animation) in order to
get an idea across...

(At least make use of the third dimension to describe SOMETHING if you
are going to include it.)

(who is being chastised by Hans for attempting to plot 100k data
points.)


P.S. the green y-axis looks really odd in your example.

Just to make it clear: this wasn't an example for the gallery, but
more or less the only asymptote example on my hard drive (excluding
examples from the manual), just to help Aditya and Jeroen play with
something.

Well, if you want to be a purist: why do you need figures at all? One
can easily represent all the data in tables and describe images like
this one in pure mathematical formulation.

> P.S. the green y-axis looks really odd in your example.

I know, but I don't know the reason for that "weirdness". I added the
axis just because I kept forgetting orientation of axes – the axes
themselves weren't part of the drawing, so I didn't try to search for
solution to make it look better.

I guess that "impress the gallery" is a translation of an expression in
French referring to the upper, low-price, standing room only balcony in
theaters, populated by an audience that is easily impressed...

Sorry, but I insurge against the frequent, abusive misuse of 3d-like
illustrations common in PowerPoint and other MSWord documents.

Sometimes, it is useful to illustrate something in perspective; in most
cases this turns out to be very marginal - nothing more than "eye
candy" - makes life sweeter!

  Actually, it's "amuser la galerie" - amuse / entertain the gallery,
rather than impress it.

Here is an Asymptote example

unitsize(1cm);
draw((-.1,0) -- (2,0),
arrow=Arrow(TeXHead));
draw((0,-.1) -- (0,2), arrow =
Arrow(TeXHead));
draw((0,0) .. (1,1) .. (2,sqrt(2)));


Below is how I have started setting this up in Context. This creates a pdf
file with the drawing, but it is not included in the final docuement.


\defineexternalfilter
[ASY]
[filtercommand={asy -tex "context" -View -outformat pdf -outname
\externalfilteroutputfile\space \externalfilterinputfile},
output=\externalfilterbasefile.out,
readcommand=\typefile,
cache=force,
location=text,
continue=yes]

\starttext
\startASY[myplot]
unitsize(1cm);
draw((-.1,0) -- (2,0),
arrow=Arrow(TeXHead));
draw((0,-.1) -- (0,2), arrow =
Arrow(TeXHead));
draw((0,0) .. (1,1) .. (2,sqrt(2)));

\stopASY
\externalfigure[myplot]
\stoptext

Sorry for the late reply. You just need to change a few options:

\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
       unitsize(1cm);
       draw((-.1,0) -- (2,0), arrow=Arrow(TeXHead));
       draw((0,-.1) -- (0,2), arrow=Arrow(TeXHead));
       draw((0,0) .. (1,1) .. (2,sqrt(2)));
     \stopASY
   \stopplacefigure
\stoptext

Here \startASY behaves similar to \startMPcode. To get something similar 
to \startMPenvironment in mkii, you can use beforebuffer.
