[Ironpython-users] How to override the __file__ path in c#?

[Markus Schaber]

Hi, Dasaratha,

As far as I can see, you will need to use a deeper layer of the API. Some of the Microsoft.Scripting.Hosting.ScriptEngine.CreateScriptSourceXXX() methods get a “path” argument which should be the one which ends up as the __file__ variable.

You could use CreateScriptSourceFromString() or the CreateScriptSource() overloads, where you pass the script contents explicitly.

To get the ScriptEngine instance, use the IronpPython.Hosting.Python.CreateEngine() methods.

Best regards

Subject: [Ironpython-users] How to override the __file__ path in c#?

Hi,

How to override the python’s __file__ variables path (with a custom path rather than the current executing script path) in c#?
I want to do this before the python script execution through c#. I am using the following code snippet for overriding the __file__ variable.
Please let me know if this is the correct approach or not

ScriptScope scope2;
scope2.SetVariable("__file__", "c:/temp");


When we execute the python script this is being overwritten by python automatically (to current executing script path) and I am not able to get the c:/temp path from the __file__ variable.

Please help me resolve this issue.



Thanks & Regards,
Dasaratha R
