sasmodels.exception

Utility to add annotations to python exceptions.

exception sasmodels.exception.WindowsError

Bases: exceptions.Exception

Fake WindowsException when not on Windows.

args
message
sasmodels.exception.annotate_exception(msg, exc=None)

Add an annotation to the current exception, which can then be forwarded to the caller using a bare “raise” statement to raise the annotated exception. If the exception exc is provided, then that exception is the one that is annotated, otherwise sys.exc_info is used.

Example:

>>> D = {}
>>> try:
...    print(D['hello'])
... except:
...    annotate_exception("while accessing 'D'")
...    raise
Traceback (most recent call last):
    ...
KeyError: "hello while accessing 'D'"
