Re: [IronPython] Need a Good Embedded Example

2007-10-16 Thread Dino Viehland 
Yep, we've temporarily ripped out all pre-compilation support from v2.0 to make 
the refactoring work easier so pyc definitely won't work there (and there's 
really no way to make it work there w/o a rather large amount of work).

Hi Dino,

Is this why I am having trouble with the pyc.py sample? It does say
1.01 in the description so maybe I should expect issues :-)

Traceback (most recent call last):
  File pyc.py, line 35, in Initialize
  File , line 0, in _stub_##227
AttributeError: 'NamespaceTracker' object has no attribute 'CompilerSink'

Thanks,
Davy

Re: [IronPython] Need a Good Embedded Example

2007-10-16 Thread Dino Viehland 
Are you looking for samples in v1.0 or v2.0?  The code you quoted below is some 
version of v2.0 (we're still working on the final tweaks to what will become 
the new, final, hosting model).

Subject: [IronPython] Need a Good Embedded Example

I have been looking for a good example of embedding IronPython in a c# 
application. I am under the impression that there have been some major changes 
in the way this is done from version 1.1 to 2.0.

This is what I found at the Python Cookbook site:

namespace IronPythonScriptHost
{
class Program
{
static void Main(string[] args)
{
string code = "print \"Hello \" + Name";
Script.SetVariable ("Name", "Me");
Script.Execute("py", code);
}
}
}

That's nice, but doesn't really help me to know how to get variable output from 
the script back to my c# code. I also need to know how to call scripts with 
multiple statements and whether all variables need to be set on the script 
object, or can their declaration just be part of the script code.

Is there a good and simple example anywhere that shows how to host the 
IronPython engine in a c# app and let users manipulate your program objects via 
ipy scripts?

Thanks!

Re: [IronPython] Announcement: Project to get some CPython C extensions running under IronPython

2007-10-16 Thread Davy Mitchell

I was most concerned with data types (and converting) which for
statistical based computing needs to be exact. It is a great plus for
DotNet to have common types between languages. After working for years
in mixed VB6/C++ COM applications I really appreciate that :-)

Are Resolver Users looking to reuse their existing code in
spreadsheets or just have the same facilities? If the latter then SWIG
for Dotnet seems a better option than COM and is more Mono friendly.

Cheers,
Davy
