[IronPython] Modules available for IronPython?

[Bruce Christensen]

Yes, you can drop in the CPython libraries, and they'll work (with some
exceptions, which Dino noted below). For example:

C:\Ip\IronPython>set IRONPYTHONPATH=C:\Python24\Lib

C:\Ip\IronPython>ipy
IronPython 1.0.2383 (Beta) on .NET 2.0.50727.42
Copyright (c) Microsoft Corporation. All rights reserved.
>>> import os.path
>>> import string
>>> string.join(os.path.split(os.path.realpath(os.curdir)), "****")
'C:\\Ip****IronPython'
>>>

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=Regr
ession%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,
