Hello,
I'm trying to get some commercial code for a simple object database we have
written for Python 2.6 to work with IronPython 2.6. In Python 2.6 the return
type of pickle.dumps() is str, which is of course a byte string. In
IronPython 2.6 it is also str, which is of course a unicode string.

Hi everyone!
I would like you ask this question that I seem not to get an answer
for anywhere.
What is the advantage of using ironpython compared to using only
powershell? Or is it just a personal choice which one you like the best?
Taste comes into it a lot. For example

Is this a theoretical problem at this stage or an actual problem?
Its an actual problem with SQLiteParameter.Value from the SQLite ADO.NET
provider. I think our original CPython code is a bit sloppy with respect to
the distinction between text strings

Hi Michael,
[snip]
My opening paragraph may be ambiguously worded - by
'interoperability'
I didn't mean the ability to run the same code unchanged on CPython
and IronPython (I have to change the code anyway to use a different
database
adapter) - I meant interoperability between
Hello,
Lets create a bytes instance from a str, and convert it back to a str.
a = bytes(ord(c) for c in Hello World)
a
b'Hello World'
str(a)
b'Hello World'
As you can see, the leading b and the quotes become part of the string,
which is unexpected. I guess the conversion is using __repr__
I would humbly suggest that if you were to use adodbapi for your database
access, the adapter would take care of all of this for you, and will also
work in Python 3.0. Unfortunatly, the last remaining bug in adodbapi (caused
by a bug in the IronPython COM interface) is in this exact area --

Unfortunately there's probably going to continue to be a bunch of corner
cases related to bytes/str/unicode until we move to 3.0. But hopefully
we can come up w/ reasonable workarounds for most of them.
In this case it seems like we should define __str__ on bytes and make
it return a Unicode

Because in IronPython str is just an alias for Unicode. I think it would
be extremely broken for us to alias all 3 to unicode especially when bytes
clearly has a different meaning.

Robert:
Thanks for documenting this. I am contemplating a new fork of adodbapi
based on ADO.NET rather than COM (my target is Linux/mono so COM is out of
the question.) I will very likely run into this problem
I prefer to use powershell if I'm dealing with files, registry
entries, AD, and (especially!) external programs - your classic shell
scripting tasks, essentially. It's what it was designed for.
Python, on the other hand, is a fantastic language for building and
extending applications.

Hello everybody,
Could somebody help to setup simple delegate in IronPython.
I just need to generate event when list structure gets filled with data,
and update GUI element.
thanks a lot,

Hi all,
Are there plans to release versions of 2.6 for both .NET 2.0 .NET
4.0, or are the 4.0 previews just for demonstration?
Also, (as nobody noticed my earlier mail :)), are there plans to
support adding 2.6 to the GAC? When I asked for 2.0, it was mentioned
that there are more stringent
24 matches
