picklecachefun

Cache the results of function calls to disk, using pickle, similarly to functools.cache in the standard library.

Example usage

Basic use:

import picklecachefun

@picklecachefun.cache('/path/to/filename.pkl')
def some_function(some_arg):
    ....
    return stuff

A default cache root can be set too:

picklecachefun.set_cache_root('/path/to/cache')

@picklecachefun.cache('filename.pkl')
...

The cache can be invalidated through setting a min_time. In short, set the min_time to the timestamp of when you most recently changed the function definition and need to invalidate the cache.

@picklecachefun.cache('filename.pkl', min_time="2023-12-04T20:56:48")
...
