cachalot 0.1.0

Minimal persistent memoization cache

[](https://badge.fury.io/py/cachalot)

# Cachalot
Cachalot is a minimal persistent memoization cache. It provides a decorator, that stores function result for future use. Perfect for heavy computations and I/O operation (such as web requests). On backend, it uses TinyDB for storage.

## Features
- Simple usage via decorator
- Persistent caching
- Key expiration
- Maximum cache size, to prevent bloat

## Installation
Cachalot requires Python 3.5 or newer to run.

**Python package**

You can easily install Cachalot using pip:

`pip3 install cachalot`

**Manual**

Alternatively, to get the latest development version, you can clone this repository and then manually install it:

```
git clone [e-mail]:radek-sprta/cachalot.git
cd cachalot
python3 setup.py install
```

## Usage
```python
from cachalot import Cache

@Cache()
def expensive_function():
return expensive_calculation()
```

### Advanced usage
```python
from cachalot import Cache

@Cache(path='cache.json', timeout=3600, size=5000)
def expensive_function():
return expensive_calculation()
```

`path`: Path to the database file. Defaults to .cache.json.
`timeout`: How long should the data be cached in seconds. Defaults to 86400 (1 day).
`size`: Maximum number of keys cached. Defaults to 10000.
