Analyzing an IronPython Scope
- by Vercinegetorix
I'm trying to write C# code with an embedded IronPython script. Then want to analyze the contents of the script, i.e. list all variables, functions, class and their members/methods.
There's an easy way to start, assuming I've got a scope defined and code executed in it already:
dynamic variables=pyScope.GetVariables();
foreach (string v in variables)
{
dynamic dynamicV=pyScope.GetVariable(); /*seems to return everything. variables, functions, classes, instances of classes*/
}
But how do I figure out what the type of a variable is? For the following python 'objects',
dynamicV.GetType()
will return different values:
x=5 --system.Int32
y="asdf" --system.String
def func():... --IronPython.Runtime.PythonFunction
z=class() -- IronPython.Runtime.Types.OldInstance, how can I identify what the actual python class is?
class NewClass -- throws an error, GetType() is unavailable.
This is almost what I'm looking for. I could capture the exception thrown when unavailable and assume it's a class declaration, but that seems unclean. Is there a better approach?
To discover the members/methods of a class it looks like I can use:
ObjectOperations op = pyEngine.Operations;
object instance = op.Call("className");
foreach (string j in op.GetMemberNames("className"))
{
object member=op.GetMember(instance, j);
Console.WriteLine(member.GetType());
/*once again, GetType() provides some info about the type of the member, but returns null sometimes*/
}
Also, how do I get the parameters to a method?
Thanks!
