[IronPython] IronPython 2.0 Errors...

[António Piteira]

Those classes probably won’t be triggered unless I execute the code.

 

Consider this sample code:

 

import sys,clr

clr.AddReference(“System.Windows.Forms”)

from System.Windows.Forms import *

 

frm = Form()

frm.Show()

 


#some error here, after the show

 

If I execute the code the form will still be shown and only then I would be
able to catch the error.

What I want is to catch the errors without showing the form (considering
this code).

 

Thanks for your cooperation

 

 

 

 

Don't you think PythonException or related classes would be sufficient?

I get it, I'm not really surprised
 I was hoping that maybe there was a way
to use scriptSource.Compile(options,errorTracker), or something like that,
and get the errors from errorTracker or some kind of sink.

 

Very much apreciated for your time.

Are you familiar with "the halting problem"? :) (

The only reliable way to find if a particular program returns a runtime
error is to execute the program.  For limited, targeted cases, (such as
importing modules) you could write an analyzer program which would be
*often* right -- but I could create a program  that tricks your analyzer
into reporting a problem where none exists.  Consider this:

 

import sys

sys.modules['foo'] = type(sys)('foo')

import foo

 

Your static analyzer would have a tough time recognizing that this program
would not raise a runtime error.

Those things are run-time errors (failed imports et al). You would

possibly look at the parse tree for any imports and determine if the

modules to be imported exist, but that sounds like a lot of trouble :)

Hi,

 

I'm trying get all runtime errors without actually executing the code. I can
get all syntax errors using the parser, but runtime errors like "import ys"
and stuff like that I', not able to.

Is there any way to do this?

 

Thanks,

Vision
