Re: [IronPython] -X:EnableProfiler and DLR hosting API
Thank you for the answer :) I found this article which tells me that a script can now enable the profiler from within itself: http://blogs.msdn.com/curth/archive/2009/04/11/profiler-part-ii-poor-man-s-code-coverage.aspx http://blogs.msdn.com/curth/archive/2009/04/11/profiler-part-ii-poor-man-s-code-coverage.aspxSo I used that method instead, like this: def begin_profiler(): import clr clr.EnableProfiler(True) clr.ClearProfilerData() def end_profiler(): ticks_to_ms = 0.1 clr.EnableProfiler(False) # show top 20 sorted by exclusive time for p in itertools.islice(sorted(filter(lambda item: item.Calls != 0, clr.GetProfilerData(True)), key=lambda item: -item.InclusiveTime), 20): print '%s\n%f\t%f\t%d' % (p.Name, p.InclusiveTime * ticks_to_ms, p.ExclusiveTime * ticks_to_ms, p.Calls) Seems to work very well :) /Mads ___ Users mailing list Users@lists.ironpython.com http://lists.ironpython.com/listinfo.cgi/users-ironpython.com
Re: [IronPython] FW: App_Script Problem in latest IronPython for ASP.Net
I've reproduced this issue. Microsoft.Web.Scripting seems to be doing the right thing ... detecting changes in App_Script and calling runtime.ExecuteFile(path) for the files that changed. However, that's not having any effect. This definitely works stand-alone, so I'll drill into this more.

Re: [IronPython] Accessing scope variables
The only way I can think of doing this today would be to use our Parser
And PythonWalker classes to parse the func def and then walk it and look
for NameExpressions.
You'd also need to look for GlobalStatement's, AssignmentStatement,
and AugmentedAssignmentStatement to know if it was a global or not.
OTOH if we fixed this bug (which you can vote on):
http://ironpython.codeplex.com/WorkItem/View.aspx?WorkItemId=15398
you could walk the function objects, get their func_code, and then
look at co_names:
x = 42
def f():
print x
y = 42
c = f.func_code
c.co_varnames
('y',)
c.co_names
('x',)
Which looks like it has the global names which would be resolved against
your scope. I've slowly been fixing more and more of function code but
haven't gotten to this one yet :(

Subject: [IronPython] Accessing scope variables
Hello,
We are hosting IronPython in our Windows forms-based application to
allow our customers to write scripts. We allow customers to use our own
variables within the script.
public class Variable
{
string Name;
int Value;
..
}
..
Variable v1 = new Variable(Length, 10); // Create a variable with
Name=Length and Value=10
vars.Add(v1);
Variable v2 = new Variable(Width, 10);
vars.Add(v1);
vars.Add(v2);
We set custom variables in scriptScope like this.
..
foreach (IVariable aVariable in vars)
{
scriptScope.SetVariable(aVariable.Name, aVariable);
}
..
With this, user can write a function like this
def CalcArea() :
return Length * Width
In our application, we are dealing with hundreds of variables and
functions. As the user deletes or modifies a Variable (here Length and
Width), they would like to know where the variables are used. In this
example, the variable Length and Width are used in CalcArea function. I
can't find a way to identify the list of custom variables used within a
function using the API.
Any suggestions? Thanks a lot.

[IronPython] Reflection.Emit from IronPython: What is the equivalent of typeof() in C# ?
Hello,
I'm attempting to drive the Reflection.Emit API from IronPython. In C#
typical Reflection.Emit use makes use typeof(...) facility in C#, to enable
the determination of types without needing an instance of that type.
For example, to create an array of .NET CTS Strings in IL from C# one might
do:
generator.Emit(OpCodes.Newarr, typeof(string));
where the second argument to Emit is the element type of the array.
I've tried various alternatives from IronPython, including
generator.Emit(OpCodes.Newarr, System.Type.GetType('System.String'))
generator.Emit(OpCodes.Newarr, str().GetType())
generator.Emit(OpCodes.Newarr, System.String().GetType())
generator.Emit(OpCodes.Newarr, clr.GetClrType(System.String))
however, all of these result in RuntimeType[] rather than String[] in the
generated CIL.
How do I get typeof(System.String) from IronPython?

You can also just use the type like System.String to avoid having to create
an instance of the type.

import clr
clr.GetClrType(System.String)
System.RuntimeType object at 0x002B [System.String]
