schrodinger.models.diffy module¶

Need a diff in a jiffy? Use diffy!

schrodinger.models.diffy.get_diff(new_state, old_state)¶: Given two states of an object, calculate what changed between them.

class schrodinger.models.diffy.ListDiff(added, removed, moved)¶

Bases: tuple

schrodinger.models.diffy.get_diff_list(new_state, old_state)¶

Calculate what was added, removed, and moved between two states of a list.

Note that items are compared by identity not equality (ie is rather than ==).

Returns:	A namedtuple describing what was added, removed, and moved between two lists. See `get_added`, `get_removed`, and `get_moved` more details.
Return type:	ListDiff(set, set, set)

class schrodinger.models.diffy.SetDiff(added, removed)¶

Bases: tuple

schrodinger.models.diffy.get_diff_set(new_state, old_state)¶

Calculate what was added and removed between two states of a set.

Returns:	A namedtuple describing what was added and removed.
Return type:	SetDiff(set, set)

schrodinger.models.diffy.get_removed_set(new_state, old_state)¶

Calculate what was removed between two states of a set.

Return type:	set

schrodinger.models.diffy.get_removed_list(new_state, old_state)¶

Returns:	A set of tuples, each describing an item that was removed and and its index in `old_state`
Return type:	set((object, int))

schrodinger.models.diffy.get_added_list(new_state, old_state)¶

Returns:	A set of tuples, each describing an item that was added and and its index in `new_state`.
Return type:	set((object, int))

schrodinger.models.diffy.get_added_set(new_state, old_state)¶

Calculate what was removed between two states of a set.

Return type:	set

schrodinger.models.diffy.get_added_dict(new_state, old_state)¶

Returns:	A dictionary with items in `new_state` but not in `old_state`.

schrodinger.models.diffy.get_moved_list(new_state, old_state)¶

Returns:	A set of tuples, each describing an item that was moved and and its index in `new_state`
Return type:	set((object, int))
