find changes in a directory
Project description
FileSpy is a simple library that helps you detect filesystem changes.
API
CHANGE_TYPE
CREATED = 0
DELETED = 1
MODIFIED = 2
make_snapshot
make_snapshot(path, followlinks=False) -> dict()
path - directory path
followlinks=False - follow links when traversing through directory
Creates a directory snapshot. Snapshot doesn’t hold any information about directory in which this snapshot was done, so you can easily compare directories in a different locations.
It returns a simple dictionary, where keys is a file path and value is os.stat() of this file. It is done in a such way to make serialization of this data as simple as possible.
snapshot_diff
snapshot_diff(s1, s2) -> tuple(CHANGE_TYPE, path)
Generator that yields changes between two snapshots.
Example
s1 = filespy.make_snapshot('/dir')
time.sleep(3)
s2 = filespy.make_snapshot('/dir')
for t, path in filespy.snapshot_diff(s1, s2):
if t == filespy.CREATED:
on_create(path)
elif t == filespy.DELETED:
on_delete(path)Here we are taking snapshot of the directory /dir, then sleep for 3 seconds, take another snapshot, and finally looking at the changes.
