Does settrace work? I've seen two questions about it in as many days
that are as yet unanswered.
The short answer is no. The Wing debugger is written in C. The
SharpDevelop debugger (written in C#) does work with IronPython though.

Vincent:
I will try the first part of an answer to your question. It is a long
question, so you will probably get lots of different answers...
There are several different implementations of Python. I will talk
about the two which are most common on Windows systems. I use both.
CPython is implemented in the C++ language and uses the traditional
(or OLD, depending on your point of view) method of operating a
Windows program. It is much more mature, starts up much faster, and
has lots of available modules, including numpy, scipy and countless
others. You find it at http://python.org. <http://python.org%20> To do
Windows specific things with it, you also need pywin32
<http://sourceforge.net/projects/pywin32> . It can be used on a web
server, and several web engines such as django, are written using it.
It cannot be used as a client script on a web page.
IronPython is new, written by Microsoft in the C# language, and uses
the new .NET way of hooking things together. It is a VERY good
implementation of standard Python, but since many of the add-on
libraries were written in C++, not C#, you cannot link to them. There
is a package called IronClad which seeks to make this happen, often
successfully. ( http://www.resolversystems.com/products/ironclad/ .)
IronPython also suffers from the frustrating habit of ALL .NET
implementations of taking several seconds (which at times feels like
several minutes) to start a new process running. So while it may often
be FASTER than CPython after it finally gets going, don't even THINK
about using it for a quick command-line script. On the other hand, if
you are trying to interface with a new .NET project, it is only
reasonable way to go. It also runs on the Silverlight platform, so
can be used as a scripting language for a web client page, not only a
server page.
I have heard nothing but BAD reports about using Iron Python Studio.
However, there are several Integrated Development Environments which
work with CPython, IronPython, or both. I, personally, use Wing for
debugging, and the IDE which is built in to pywin32 for rough work.
Will Python code run as fast as C, or C++, or C# code? No. (or
almost never.) Will it run fast enough that a human user will never
notice the difference? Almost always. So what you do is prototype in
Python, where you are most productive, then if you find that some part
of your system actually needs the performance boost, you recode that
piece in C++ (or C#). I find that design changes usually do much more
to boost perceived speed than compiler changes do. Python excels at that.
So welcome aboard. You have discovered a great tool.

Hello to all.
This is my first message to the list. I would like to ask you some
basic questions about IronPython. First of all, sorry for my English.
I've just discovered IronPython, and I am actually a new-by in Python,
not an expert programmer. So maybe you'll find my questions quite
simple or naive.
I read the first chapter of the classic book for IronPython
(http://www.manning.com/foord/SampleChapter1.pdf), and in pages 7-8
the author says:
"Visual Studio 2008 integration exists in the form of IronPython
Studio, which is implemented through the Visual Studio Shell
extensibility framework. IronPython Studio can either be run
standalone (without requiring Visual Studio to be installed) or
integrated into Visual Studio. It includes Windows Forms and WPF
designers and is capable of producing binary executables from Python
projects."
I am very interested in fully understanding this sentence above,
because I currently use C++ in MS Visual Studio 2008, but I like
Python more.
So, with IronPython + Visual Studio 2008:
(1) Can I obtain compiled code from Python source, as
efficient/fast/etc. as if it was made from C++?
(2) Can I obtain executables (programs that people can install and
use, in the "normal user" language) as good/fast/efficient as I would
obtain using Visual C++?
(3) Can I easily link my Python code with existing external C/C++
libraries?
(4) (Similar to the previous one) Can I easily link my Python code
with some C/C++ source code (I mean, mixing up Python and C in the
same project, in a transparent way)?
(5) Can I use NumPy, SciPy and other key (scientific) Python libraries
in a transparent way?
(or am I just dreaming??)
Any answer will be appreciated. Thank you in advance.
