Python getrwatch Examples

Example #1

File: test.py Project: dutc/rwatch

def debug_demo(x='some data'):
    from inspect import getframeinfo
    def view(frame, obj):
        info = getframeinfo(frame)
        msg = 'Access to {!r} (@{}) at {}:{}:{}'
        print(msg.format(obj, hex(id(obj)), info.filename, info.lineno, info.function))
        return obj

    setrwatch({id(x): view})
    print(getrwatch())

    def f(x):
        x # ← here
    f(x) # ← here

    def f(x):
        def g():
            x # ← here
        return g
    f(x)() # ← here

    class Foo:
        def __init__(self, x):
            self.x = x # ← here
        def __call__(self):
            return self.x # ← here
        @property
        def value(self):
            return self.x # ← here

    foo = Foo(x) # ← here
    foo()
    foo.value

    x = 10 # not here (rebind, no push)

Example #3

def f():

    setrwatch({id(x): view})
    print({hex(k): v for k, v in (getrwatch() or {}).items()})
    print('x =', x)

    x = object()
    setrwatch({id(x): view})
    print({hex(k): v for k,v in (getrwatch() or {}).items()})

# Anyhow, if `rwatch` is installed, we can import it, and it enables two new functions in the `sys` module:

# In[6]:


import rwatch
from sys import setrwatch, getrwatch

setrwatch({})  # clean any previously installed rwatch
getrwatch()


# Finally, we need the [`collections`](https://docs.python.org/3/library/collections.html) module and its [`defaultdict`](https://docs.python.org/3/library/collections.html#collections.defaultdict) magical datastructure.
