memoi 0.1.0

provides generic methods to memoize function and method calls

Memoi

Description

A generic caching mechanism for memoizing function or method calls.

Prerequisites

• Python >= 3.10

Installation

python -m pip install memoi

Example

from datetime import datetime as dt
from memoi import cached, TextFileRepo

@cached(TextFileRepo('.'))
def f(*args, **kwargs):
    return f"this is the result of the first f() call at {dt.now().isoformat()}"

print(f())
print(f())

This will create a a sqlite database memo.sqlite, keeping track of function calls, and a text file 50/506f353d3ef92d51f3e57bae99367caf directory, containing the result of the first f() call. Obviously the timestamp from the first function call is preserved.

Changelog

Release 0.0.1

Description

Minimum Viable Product of a result caching function decorator.

Added

• decorator cached: providing a caching mechanism for return values, so the function is not executed the next time when it is called with the same arguments.

• class TextFileRepo: for caching return values of functions returning strings as text files in a configurable directory.

Release 0.1.0

Description

Multi-String support.

Changed

• cached: returns a pair of datetime and original result, the former indicating the date of first submission; can handle functions/methods that return iterables.
