ubelt.meta.dynamic_analysis module

ubelt.meta.dynamic_analysis.get_stack_frame(n=0, strict=True)

Gets the current stack frame or any of its ancestors dynamically

Parameters:

• n (int) – n=0 means the frame you called this function in. n=1 is the parent frame.
• strict (bool) – (default = True)

Returns:

frame_cur

Return type:

frame

CommandLine:

python -m dynamic_analysis get_stack_frame

Example

>>> from ubelt.meta.dynamic_analysis import *  # NOQA
>>> frame_cur = get_stack_frame(n=0)
>>> print('frame_cur = %r' % (frame_cur,))
>>> assert frame_cur.f_globals['frame_cur'] is frame_cur

ubelt.meta.dynamic_analysis.get_parent_frame(n=0)

Returns the frame of that called you. This is equivalent to get_stack_frame(n=1)

Parameters:n (int) – n=0 means the frame you called this function in. n=1 is the parent frame. Returns:parent_frame Return type:frame

CommandLine:

python -m dynamic_analysis get_parent_frame

Example

>>> from ubelt.meta.dynamic_analysis import *  # NOQA
>>> root0 = get_stack_frame(n=0)
>>> def foo():
>>>     child = get_stack_frame(n=0)
>>>     root1 = get_parent_frame(n=0)
>>>     root2 = get_stack_frame(n=1)
>>>     return child, root1, root2
>>> # Note this wont work in IPython because several
>>> # frames will be inserted between here and foo
>>> child, root1, root2 = foo()
>>> print('root0 = %r' % (root0,))
>>> print('root1 = %r' % (root1,))
>>> print('root2 = %r' % (root2,))
>>> print('child = %r' % (child,))
>>> assert root0 == root1
>>> assert root1 == root2
>>> assert child != root1
