ironpython exception line number

[Troels Thomsen]

Hello ,

When an exeption occurs in a IronPython executet script, and I print the
sys.exc , i get something ugly like the example below.
How can I get the fileName and line number?

Thx in advance

RE: ironpython exception line number

Given a file foo.py:

def f():

You should get these results:

IronPython 1.0.60816 on .NET 2.0.50727.312
Copyright (c) Microsoft Corporation. All rights reserved.

>>try:

.... execfile('foo.p y')
.... except IndentationErro r, e:
.... import sys
.... x = sys.exc_info()
....

>>print x[1].filename, x[1].lineno, x[1].msg, x[1].offset, x[1].text, x[1].args

foo.py 2 unexpected token <eof1 ('unexpected token <eof>', ('foo.py', 2,1, ''))

>>>
>>>

Which is very similar to the result you get from CPython although we seem to disagree about what we expect next.

Python 2.5 (r25:51908, Sep 19 2006, 09:52:17) [MSC v.1310 32 bit (Intel)] on win32
Type "help", "copyright" , "credits" or "license" for more information.

>>try:

.... execfile('foo.p y')
.... except IndentationErro r, e:
.... import sys
.... x = sys.exc_info()
....

>>print x[1].filename, x[1].lineno, x[1].msg, x[1].offset, x[1].text, x[1].args

foo.py 2 expected an indented block 9 ('expected an indented block', ('foo..py', 2, 9, ''))

If you're hosting IronPython and catching this from a .NET language then you'll be catching the .NET exception. In that case you can access the original Python exception from ex.Data["PythonExceptio nInfo"]. Alternately you could catch PythonSyntaxErr orException and access its properties (Line, Column, FileName, LineText, Severity, and ErrorCode).
