Efficiently cache calls to functions

cacholote

Efficiently cache calls to functions

Quick Start

>>> import cacholote
>>> cacholote.config.set(cache_db_urlpath="sqlite://")
<cacholote.config.set ...

>>> @cacholote.cacheable
... def now():
...     import datetime
...     return datetime.datetime.now()

>>> with cacholote.config.set(use_cache=True):
...     now() == now()
True

>>> with cacholote.config.set(use_cache=False):
...     now() == now()
False

Configuration

Configuration settings can be accessed using cacholote.config.get() and modified using cacholote.config.set(**kwargs). It is possible to use cacholote.config.set either as a context manager, or to configure global settings. See help(cacholote.config.set).

Defaults are controlled by environment variables and dotenv files. See help(cacholote.config.reset).

Workflow for developers/contributors

For best experience create a new conda environment (e.g. DEVELOP) with Python 3.10:

conda create -n DEVELOP -c conda-forge python=3.10
conda activate DEVELOP

Before pushing to GitHub, run the following commands:

1. Update conda environment: make conda-env-update
2. Install this package: pip install -e .
3. Sync with the latest template (optional): make template-update
4. Run quality assurance checks: make qa
5. Run tests: make unit-tests
6. Run the static type checker: make type-check
7. Build the documentation (see Sphinx tutorial): make docs-build
