Function full path

Ignition
1

Hello,

Is there a way to get the complete path of a function?
Example:
Let's say I have a function defined inside "Scripts > DB > "FunctionName".
So, When an error occurs within FunctionName, I want to log "Scripts.DB.FunctionName" as the originator of the error.

Right now I am using "inspect.currentframe()" method of inspect library but this only gives me the name of the function without the path of the script file in which the function exists.
inspect.currentframe() returns FunctionName but I want "Scripts.DB.FunctionName".

Thanks,
Ajay

I'm not sure I understand what you want...

Let's say you have a script called Foo which contains a function called bar.
bar raises an error, which you catch from some other functions.
You want to log the full path of bar from that except clause, is that it ?
you can use

func.__code__.co_filename

to get the path of the module where the function is, then append the function name to it

func.__name__

I use something like this

class errorHandler():
	''' decorator to wrap functions with a generic error handler '''
	def handleError(self, fn, values, trace):
		# Format the failed call into the same format that it would written in code
		try: fnPath = '%s.%s' % (fn.func_code.co_filename.split(':')[1].replace('>',''), fn.__name__)
		except: fnPath = fn.__name__
		
		argsFmt = ','.join(['%r' % x for x in values['args']])
		kwargsFmt = ','.join(['%s=%r' % (k,v) for k,v in values['kwargs'].items()])
	
		callString = '%s(%s)' % (fnPath, ','.join(filter(None,(argsFmt,kwargsFmt))))

        # do something with the failed function path here
	
	def __call__(self, fn):
		# returns the decorator itself, which accepts a function and returns another function
		# wraps ensures that the name and docstring of 'fn' is preserved in 'wrapper'
		@functools.wraps(fn)
		def wrapper(*args, **kwargs):
			# the wrapper passes all parameters to the function being decorated		
			try:
				return fn(*args, **kwargs)
				
			except (Throwable, Exception) as e:
				self.handleError(fn, locals(), traceback.format_exc())
				return {'ErrMsg':e}
				
		return wrapper

# decorator to apply the error handler wrapper to any function we want
@errorHandler() 
def someFunction():
    return value
