Description: # cachepot
Yet another Python cache library. This has Python 3 typing hints.
## Usage
```python
>>> from cachepot.store import CacheStore
>>> from cachepot.backend.filesystem import FileSystemCacheBackend
>>> from cachepot.serializer.pickle import PickleSerializer
>>> store = CacheStore(
... namespace='testing',
... key_serializer=PickleSerializer(),
... value_serializer=PickleSerializer(),
... backend=FileSystemCacheBackend('/tmp'),
... default_expire_seconds=3600,
... )
>>> store.put({'some': 'key'}, {'some': 'value'})
>>> store.get({'some': 'key'})
{'some': 'value'}
>>> store.put({'some': 'short expiring key'}, {'some': 'value'}, expire_seconds=10)
```
### Proxy interface
```python
result = store.proxy(some_func)(some_args)
```
is same as
```python
result = store.get(some_arg)
if result is None:
result = some_func(some_args)
store.set(result)
```
In short, this works as proxy. This helps to make codes straight forward.
proxy method can be passed two arguments `cache_key` and `expire_seconds`.
## Core Idea
- Typing supports
- Generic serializers ... [pickle](https://docs.python.org/3/library/pickle.html), [JSON](https://tools.ietf.org/html/rfc8259), and more serializers you can define.
- Generic backends ... Currently supports only filesystem backend. But it is not so difficult to add Redis or the other KVS backends. And of course you can define own backend.
- Proxy interface
## Development
You can install requirements with pipenv
```shell
$ pipenv install
```
### Test
```shell
$ flake8
$ mypy .
$ python3 -m unittest discover
```
