I have some logging utilities so that when I write library code, I just use the
following.
from logutil import Logger
log = Logger(__name__)
And from then on I just use log, to do the logging of that module.
But now I would like to write a decorator trace, so that a decorated
function would log, its arguments and result.
Something like:
def trace(func):
def wrapper(*args):
log(DEBUG, "=> %s%s" % (func.__name__, args))
result = func(*args)
log(DEBUG, "%s => %s" (func.__name__, result))
return wrapper
The problem is that with this decorater, the log function
used, will be the log function defined where the decorator
is written and I would prefer it to use the log function
where it is used, so that it uses the same log function
as the function it decorates.
