Hi,
I've found that the from __future__ import ... works in .py file run by
ipy.exe but not when I create an engine in C#.
test.py:
from __future__ import division
print 'done'
test.cs:
using Microsoft.Scripting;
using Microsoft.Scripting.Hosting;
using IronPython.Hosting;
namespace TestDuture
{
public class Test
{
static void Main(string[] args)
{
ScriptEngine engine = Python.CreateEngine();
ScriptRuntime runtime = engine.Runtime;
ScriptScope scope = runtime.CreateScope();
ScriptSource source =
engine.CreateScriptSourceFromFile("test.py");
source.Execute(scope);
}
}
}
build command:
csc /r:Microsoft.Dynamic.dll /r:Microsoft.Scripting.core.dll
/r:Microsoft.Scripting.dll /r:IronPython.dll /r:IronPython.Modules.dll
test.cs
Running test.exe throws exception:
C:\Users\dev\Documents\FutureTest>test.exe

Am I missing something? It works ok when I add __future__.py from Python
2.6.
