ambush

Example:

I would like to how does this Popular Package use my function.

test.py
1from main import Popular
2
3def foo():
4  print("In foo()")
5
6p = Popular()
7p.register(foo)
8p.run()
main.py
 1from run import Runner
 2
 3
 4class Popular:
 5
 6  def register(self, cb):
 7    self.callback = cb
 8
 9  def run(self):
10    # some work
11    r = Runner(self.callback)
12    # some other work
run.py
1class Runner:
2
3  def __init__(self, cb):
4    cb()
test.py
 1from main import Popular
 2
 3def foo():
 4  print("In foo()")
 5  from ambush import detector
 6  detector()
 7
 8p = Popular()
 9p.register(foo)
10p.run()

python test.py

Output:

Who is calling current function
==========================================================
In file:
/Users/tmp/run.py

class Runner:
    # by caller function:
    def __init__ in line 3
        ...
        # actually call:
    cb() # in line 4
        ...

Peek:

  def __init__(self, cb):
    cb()
