[Python.NET] How to show the Console window

[Oleksii Bidiuk]

Hi Sharon,

I haven't found a way to run a console, but I had achieved a similar effect
by redirecting the stdout and stderr from within Python (as suggested some
time ago by Guido himself in a related embedded CPython post) to a .NET
object and then show the incoming strings in a TextBlock (I am using a WPF
app that hosts Python.NET). Below is a very short description of what I have
done. Please let me know if this is indeed what you were looking for (or
perhaps somebody else), I will prepare a more detailed post then (need to
recap details from code).

To achieve having 'live' console output I have used some 'setup script' and
'clean up' scripts executed before and after the user-defined script. In the
setup script I first backup the curent value of sys.std* objects and then
assign my own (.NET) object to sys.stdout and in the clean up part I restore
the original std* values (similar to the sample for inserting certain path
to the sys.path discussed before).

To make use of the technique described above you need to have a .NET object
that implements the same interface as python stream (meaning write,
writelines, etc methods, see dir(sys.stdout) for all the details). In my
experience write() and writelines() is enough. Having that you can pass an
instance of such object to your Python code. As soon as you have the
information coming through your .NET object methods you can do things like
raising events, adding text to GUI, dump to a file, etc. It does require a
bit of additional work, (which I honestly already expected to see already in
Python.NET) and to some extend similar to the concept of console redirection
per script context in IronPython, although in IronPython it is done in a
'native' .NET way.

I am not sure this is THE best solution and other suggestions are more than
welcome!
