[IronPython] Ironclad v0.2 released

Hi all Please enjoy Ironclad v0.2, which is now available from: http://code.google.com/p/ironclad/downloads/list Major changes are as follows: * Ironclad now uses IronPython 2.0b1 for everything. * It is now possible to use all the functions and types -- and their methods -- from the bz2 modul

(Cross-posted from the c-extensions-for-ironpython google group -- I thought a few people here might be interested too :)) Hi all Our original goal for 0.5 was to import numpy, from IronPython, and do something with it. With one monstrous caveat, we have reached that goal; the problem is that

Hi all I'm about to file this on Codeplex, but I think I've tracked down a subtle and nasty bug, which is blocking Ironclad with numpy (it fatally breaks matrices and masked arrays), and I feel compelled to shout loudly about it to ensure it doesn't get lost in the noise of the impending 2.0

[IronPython] (ironclad) is it possible to get the current ScriptEngine?

Hi all At the moment, when a user types 'import ironclad', I create a new ScriptEngine and set that up to allow .pyd imports; I then abuse path_hooks to use the new engine to do the imports, and copy them into the original engine's sys.modules. Clearly, this is evil and wrong on any number of

I should point out ahead of time that there's no mmap module in IronPython at the moment, and so memory-mapped ndarrays don't work yet -- although most of the usual numpy save/load bits do work, so you'll probably be fine (unless they're too big to fit in memory). Dan Shechter wrote: Here! I

Re: [IronPython] .exe is not pre-compiled

Generally, CPython modules have the .pyd extension -- and, in fact, Ironclad will only detect and handle attempts to import .pyd files. So, sadly, it won't help you here. It wouldn't be hard to make Ironclad handle .exe files, but the likelihood of it doing anything useful with them is minimal.
