filespy

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.
