debug-cache 0.0.1

A way to speed up debugging and testing.

Note. This is Alpha software, use with caution.

A cache meant to speed up debugging and testing process. Stores intermediate results in files.

Installation

pip install debug-cache

Usage

from debug_cache import DebugCache
cache = DebugCache(path='/path/to/debug_cache')

# or just use default
from debug_cache import cache

First debug_cache usage is to fasten repeated and heavy calls to tighten edit/rerun loop:

@cache.cached
def some_function(x, y):
    # do something
    return res

Second debug_cache usage is to check that function results didn’t change. Useful when refactoring or optimizing:

# Check that function results didn't change, they need to be cached first
@cache.checked
def some_function(x, y):
    # ...

# Same, but cache first time, check all subsequent ones
@cache.checked(strict=False)
def some_function(x, y):
    # ...

This will stop and start debugger if function results don’t match ones saved earlier. Strict version also stops if no cached results are found.
