Hi all,
I'm working on a MPL build for OS-X, and I'd like to be able to write scripts that will test as much as I can. In particular, I want to have this build work with Numeric, numarray and numpy.
To script that test, I need to be able to set numerix in a script, rather than in matplotlibrc. Can that be done?
While we're at it, it would be great if ANY of the config items in matplotlibrc could, instead, be set at run time in a script. I now a number of them can, but is there a standard way to do, and will it work with ALL the items in there?
Another note: it seems that numerix is very good at taking input from any of the Num* packages, regardless of which one is being used internally. Given that, I'm thinking of aiming for the future with my OS-X package, and just using numpy, and not bothering to build in support for the other two. any thoughts.
-Chris

Yep, just do
from pylab import *
rcParams['numerix'] = 'numpy'

rcParams is the standard way and I think works for all items.

If I was developing something now, I would only bother supporting numpy.

For testing you may also take advantage of command-line arguments:
python examples/image_demo.py --Numeric
for example, runs using Numeric as the numerix setting.
The relevant code in numerix/__init__.py is:
for a in sys.argv:
if a in ["--Numeric", "--numeric", "--NUMERIC",
"--Numarray", "--numarray", "--NUMARRAY",
"--NumPy", "--numpy", "--NUMPY", "--Numpy",
]:
which = a[2:], "command line"
break
del a
If such a command-line option is found, it overrides everything else.

well, duh. sorry for being such and idiot, but I'm surprised that you can set numerix after importing pylab.

That's my thought too, but I think I'll probably build Numeric an NumPy in anyway, as it's not hard to do.

Excellent! that will make things much easier.
