Hi,
I get this message trying to get the modules.
Am I missing something?
Thanks

All -
It is with great pride and joy that I finally release the first alphas
of not one, not two, but three distributions to CPAN:
* PDL::Drawing::Prima - PDL bindings for many Prima::Drawable functions
* App::Prima::REPL - a first attempt at a grapical PDL workspace
* PDL::Graphics::Prima - 2D plotting library for PDL built on Prima
You can install all of these using standard CPAN methods. For example,
at your system prompt you could install PDL::Graphics::Prima like so:
cpan PDL::Graphics::Prima
The only external dependency you'll need is a C compiler. If you've
not installed Prima before and you use Linux, you'll need your X11 dev
files to compile that module, too. (On Windows and Mac, if you have a
C compiler, you already have everything you need to compile Prima.)
PDL::Drawing::Prima uses the power of PDL's threading engine to
automatically perform the same drawing operation over many different
input values. PDL-threaded drawing operations take all applicable
Prima drawing properties as *optional* arguments, so that (for
example) drawing a large set of lines with the same color is nearly as
simple as drawing a large set of lines with different colors. It also
adds a threaded symbol drawing function that makes it easy to draw
various standard N-gons like triangles, pentagons, stars, and asterisks.
App::Prima::REPL is my first attempt at a PDL workspace that uses
Prima. On the spectrum of Perl/PDL work spaces, it is more
user-friendly than the pdl and pdl2 shells, but it is not meant for
editing script files (it can, but it's not great) and it is not nearly
as sophisticated as Padre. It is lightly modeled after my experience
with Matlab and IDL, and it targets potential users who would like to
use PDL but who want the comfort of a GUI interface. Actually, it does
not require PDL::Graphics::Prima, or even PDL, but if you later
install them it will automatically load them for you.
PDL::Graphics::Prima is the root concept that spurred all these
projects and is PDL's first 2D plotting library written in Perl.
(There are external plotting libraries that have Perl/PDL bindings,
but they are written in C or FORTRAN, not Perl.) It is a highly
interactive GUI plotting library with many plotting capabilities and
many more on the way. In particular, it has capabilities to export
images in raster formats and postscript output is in progress. It is
still quite young and compared with professional plotting libraries it
will have many limitations. However, I would love new ideas and
especially help in implementing them!
I promised to release this some time in February, so here it is.
Although I intend to be very responsive to questions and requests, I
will be particularly busy this week as I am attending the American
Physical Society's March Meeting in Boston, so please be patient
waiting for me to answer any questions you may pose. Also, I really
hope that the documentation is helpful, but I know there are some
holes. I hope that it is sufficient to help you get started. If not,
please check the examples in the source tarballs for
PDL::Drawing::Prima and PDL::Graphics::Prima.
Please download, use, and let me know what you think!
David
P. S. If you're in Boston and would like to meet up, feel free to
email me. :-)
