[IronPython] Modules available for IronPython?

[Dino Viehland]

To answer your 2nd question:  What mapping are you referring to in particular?  Our List class does implement both IList and IList<object> so it should pass through to anything that takes one of those.

Okay, thanks. I have experience in both Python and .NET, so IronPython seems like a natural extension. My concern is that common Pythonic solutions and patterns that I'm familiar with will not work based on lack of support for built-in libraries. Specifically, I'm referring to modules like os and string which fail to import. Are you saying that I can drop in the CPython implementations of these and they will work?

On a separate thread, I was surprised that there is no direct mapping between a Python list and the IList interface, even though such a mapping exists for string. In general, what is the logic behind the mappings and is the complete list documented?

That's a pretty good explanation, but when speaking of standard modules a distinction needs to be made between the built-in modules and the standard modules that are written in Python.

For the built-in modules we typically write these, and if you let us know which owes you need it'll help us prioritize them for the future.  Sometimes it takes us a while (e.g. socket was very popular, and Seo wrote his own socket module rather than wait for us).

For the standard library modules our goal is actually to support it on IronPython.  If you download CPython you can copy it's lib directory to IronPython's and start using all of those standard modules.  We test IronPython against the CPython regression suite and modules so we try and make sure these work.  This page http://www.codeplex.com/Wiki/View.aspx?ProjectName=IronPython&title=Regression%20Tests on CodePlex captures the state of the regression suite and is fairly up to date.

If you add the Python standard library to your sys.path, you will find that the vast majority of it works.

If you find modules (or parts of modules) that don't work, and aren't recorded on the codeplex bug tracker, then report them here and they will be scheduled to be fixed 'some time'.

I *think* that is a basically correct summation of the situation. Some parts of the standard library are implemented in C and *may* never work with IronPython, although Seo has (had ?) something in progress that may resolve that.

All the best,
