I had a look at this a few months ago. Both numarray and Numeric use an amorphous char array for storage. A simple wrapper would mean a lot of unmanaged memory moving around... not a desirable situation. It seems to me that a rewrite using generics is most appropriate. The CLR generics should take a lot of the hard work out of the code, since the current C code spends a lot of time bookkeeping and converting to and from the element type. There are some special cases currently handled by numarray, like misaligned data and byte-swapped data. IMO these should be handled at I/O time, if possible. The biggest part of numpy is the large library of legacy code (mostly in FORTRAN) for which numpy provides interfaces. I don't know enough about Python's interop mechanisms to know the best way to port these. Jeffrey Sax Extreme Optimization http://www.extremeoptimization.com _____
From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Thane Sent: August 27, 2005 6:24 PM To: 'Discussion of IronPython' Subject: [IronPython] RE: Numpy port There are two approaches: 1) wrap the unmanaged API in managed C++, or, 2) rewrite the library in managed code (IronPython?). Also, I think the Numeric library would be preferable to Numpy, although I'd bet Numpy has a larger user base. Option 1 could be done fairly quickly, but option 2 is the best long-term solution. Several years ago I wrote a COM wrapper for many of the Numpy functions without too much pain. Wait, it was MFC. There must have been a lot of pain; I've just forgotten about it :-) Math: Do you (does anyone?) have an idea of what it would take to port Numpy, etc, to .NET? I'm not much of a C programmer (I can do it, but I can't really do big, UNIX-y projects), and have never studied the problems of porting it to MC++ or C++/CLI. _____ From: [EMAIL PROTECTED] on behalf of Martin Maly Sent: Fri 8/26/2005 11:11 AM The bug ... I assume it is in the "-X:TabCompletion" console, correct? I am going to look into it.
