Hi all I'm delighted to announce the release of Ironclad v0.8 -- the all-singing, all-dancing CPython API compatibility layer for IronPython -- available now from http://code.google.com/p/ironclad/ . Notable improvements over the last release include: * Ironclad is now a neatly self-contained package -- just copy to your site-packages and 'import ironclad'. * No more silly requirement to call ironclad.shutdown() when you're finished. * A few performance improvements. * Over 900 NumPy tests now pass: in fact, almost all the tests from the core, fft, lib, linalg, ma, oldnumeric and random subpackages. * Over half the .pyds distributed with CPython 2.5 now import cleanly; some of them appear to actually work, including _hashlib and _elementtree. Ironclad grows more stable and mature with every release, and I urge IronPython users to try it out and share their impressions: feedback, whether positive or negative, is always welcomed. Cheers William
Hello William,
* A few performance improvements. * Over 900 NumPy tests now pass: in fact, almost all the tests from the core, fft, lib, linalg, ma, oldnumeric and random subpackages. I have some questions here for the science interested. I hope that they are not too specific:
* Can you also use scipy with IronClad/ResolverOne (RO)? * Can you recognize arrays with datetime objects in RO? * How is datetime information handled in RO? * What about rpy? If all the above were working in RO, it would be terrific!

Hello William, once again. I just noticed that Resolver One can only import data from Excel. In science, the common low level data exchange format is ASCII text like: CSV or tab separated. You may consider adding this. I did not find any installation instructions contained in the docs for the IronClad binaries. Where am I to put the files? Can Resolver One also recognize the python installation which is already installed on the system? Thanks in advance for answering! Kind regards, Timmie
Hi Tim Thank you for your interest! To answer your various questions order of approximately increasing complexity: Most importantly: the currently available version of Resolver One does not have numpy support built in, and for various reasons I wouldn't advise trying to integrate Ironclad with v1.3; please wait for 1.4 :-). I just downloaded R and rpy2; they don't work with Ironclad at the moment, and I'm not yet sure why. Ironclad shouldn't require any special installation: just copy the ironclad package (containing __init__.py, python25.dll and ironclad.dll) to wherever you normally put packages for IronPython (I personally have my IRONPYTHONPATH pointing to the appropriate subdirectories of a standard Python 2.5 install). Clearly my documentation is currently inadequate; I'll have to work on that for the next release. RO uses .NET DateTime objects by default, but it's perfectly possible to use python datetime objects instead; I can confirm that you can put both those datatypes into numpy arrays. While RO doesn't have an explicit CSV/TSV import option, you should be able to paste data in those formats directly into your worksheets; and, as soon as we have numpy integration out in the wild, you should be able to create ndarrays directly from your data files. Scipy support is coming along surprisingly nicely; I'd sort of forgotten about it until a couple of people asked me about it earlier today, and it turns out -- to my surprise and delight -- that it took very little work to get the SVN head running over 800 of the scipy tests (even if you can't just 'import scipy' without errors). Sadly, a lot of the modules seem to use scipy.sparse, which I can't import... yet ;-). So, we haven't built any scipy support into Resolver One yet, but hopefully we'll be able to do so without too much pain. Finally, I'm glad you like my screencast :-). I hope I haven't missed anything; let me know if I have, or if I can help with anything else. William On 29 Jan 2009, at 23:46, Tim Michelsen wrote:
