Hey folks -
I am pretty new to PDL but I'm having a lot of fun learning the language.
I'm working on a graphics module that allows me to interface with Asymptote,
a vector graphics scripting language. Asymptote has no interface to its
internals so instead I open a pipe to the interpreter and send commands
directly to the interpreter.
My question is this. I would like to send piddles to Asymptote and have it
read them in as arrays. This way, I could use PDL for my file handling and
data processing and then easily send the data to be plotted to Asymptote. I
could almost do this with pdl's print function, simply printing the pdl
straight to the pipe, except that Asymptote expects braces and comma
delimiters, so in PDL I would get
[
[ 1 2 3 ]
[ 4 5 6 ]
[ 7 8 9 ]
]
but for Asymptote I would want to have, preferably without the newlines,
{
{1, 2, 3},
{4, 5, 6},
{7, 8, 9}
}
I think I could implement this with PDL::PP (though I'm not sure how to
handle the output with C code and I've not played around with PP yet), but
I'd rather just find the original code for pdl's print statement and hijack
it for my command.
Presently, by the way, I'm accomplishing this by opening a filehandle to a
perl *string*, using pdl's print statment to print to that, processing it
using regexp's, and then sending that along to the Asymptote pipe. It works
but I'm sure it's memory inefficient and slow; there's gotta be a better
way.
Thanks!
David
