[IronPython] Line numbers in snippets...

[Alex Henderson]

Not quite... my problem is I don't have a PythonSyntaxError thrown, I
believe that's because I'm actually receiving a python generated exception,
for instance I might catch a PythonNameError when someone incorrectly spells
a variable name... and that doesn't contain any information I can use the
locate where in the snippet string the error occurred... Is there a way to
get this information out of the PythonEngine itself perhaps?

The reason I ask that I just want to implement a feature where by a user can
look at a log "view" in our product, see an error has occurred in their
script, and be able to double click the entry and navigate to our code
editor and be on the right line for fixing the problem - for this to happen
we need to be able to extract some details of where the error occurred when
using PythonEngine.Execute...

Any ideas I would be greatly appreciated... :)

Chez,
