Find function name in function

[Sean Ross]

Here's something that gets you a little bit closer to what you're looking
for, however, you will notice that it does not resolve the issue presented
in my previous posting. I.e., if you have two (or more) aliases to a
function and you call them in the same line of code, WhoMightIBe() cannot
determine which of the aliases was used, it can only tell you that the list
of possible aliases.


def WhoMightIBe():
    "returns name and/or possible alias' of called calling function"
    import inspect, re
    stack = inspect.stack()
    # get name of function as listed in def statement
    defname = eval(stack[1][-3])
    # get the source line where function is called
    srcline = stack[2][-2][0].strip()
    # extract function names from source line (robust? ...doubtful)
    pattern = re.compile(r'[a-z,A-Z,0-9,_]+\(')
    matches = [txt.replace('(','') for txt in pattern.findall(srcline)]
    # see which function name(s) alias(es) our target function
    possibles = [funcname for funcname in matches if eval(funcname) is
defname]
    return possibles

def XXX():
    print WhoMightIBe()

XXX()
yy=XXX
a= yy()
zz=XXX
zz()

print "%s %s"%(yy(), zz())

#outputs:
['XXX']
['yy']
['zz']
['yy', 'zz']
['yy', 'zz']
None None
