walk(tree, path=`[]`)

source code

This function returns a branch of a dictionary tree by walking using the attribute names specified with `path`.

Parameters:

tree - A dictionary tree
path - A list of keys to be iterated until the final location

Returns:

Value of `tree` at `path` or None if such path does not exist

compare_trees(a, b)

source code

This function does an in-depth comparison of 2 dictionary trees and produces another tree of their differences. This function calls itself recursively to produce the final result.

Changed and newly set attribute values are present in the result as their new values. Removed values and branches appear as None.

Parameters:

a - Dictionary tree A
b - Dictionary tree B

Returns:

Differences between A and B

diff_type(a, b, path)

source code

This function reports which is the type of difference that was detected in `a` and `b` at `path`.

Parameters:

a - Dictionary tree A
b - Dictionary tree B
path - Location of the difference

Returns:

If the value at `path` was added in A, return CONFIG_ADDED. When it was removed in A, return CONFIG_REMOVED. Otherwise, return CONFIG_CHANGED.
