Re: [IronPython] Resolver One 1.4 beta - with IronPython 2.0

I beg to differ...

Ultimately all undelying clr's (ms/mono) rely heavily on p/invoking soit really boils down to who maintains the "low-level" bindings...Ultimately, without pinvokes you wouldn't be able to accomplishanything...

If I was able to get mmap working on Linux/windows/macosx x86/x64 inone day then I'm sure it can't be that much of a problem...

Beside managed runtimes like python/.net/java were never about beingplatform agnostic, just about being "less" platform specific...


I believe the official term is:
"write once, debug everywhere"...

I think that is a great plan. Having no P/Invokes makes it much more

Current thinking is that IronPython 3k will be the 1st version thatwilltake a dependency on .NET 4.0 so we'll have to wait until then.Having to

rely on P/Invoke is one of the main reasons we don't have this yet

(IronPython doesn't have any p/invokes today and we'd like to avoidthem if

at possible).

I know :)

I have my own C# Assembly that does mmap() on Windows/Linux withPInvoke.

I did notice though that .NET 4.0 WIll have "native" support formmap()

through System.IO.MemoryMappedFiles...
So perhaps IP 2.X will add that as well...

I should point out ahead of time that there's no mmap module inIronPythonat 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).

Here!

I can't wait to use it with NumPy.

I actually have a .NET C# assembly that does some really nasty low-level

stuff like loading data from memory mapped
files and wrapping them with IList<T> :)

I can't wait to make Ironclad/Numpy blow up :)

  Hi all,

  Version 1.4 of Resolver One, our Pythonic spreadsheet, is based on
  IronPython 2.0, and includes (alpha-level) support for numpy using
  our Ironclad project.
  We're releasing the beta tomorrow: this has a few performance
  problems (which are being addressed - many thanks to Dino Viehland
  for helping with this!) but is otherwise functionally complete.
   If you're interested in trying it out, drop me a line!


  Best regards,

  Giles
